Introduction

The m� has been developed to provide a comprehensive, yet simple-to-use means of monitoring, recording and control refrigeration temperatures and other aspects of refrigeration plant operation. It is intended for use in small to medium food storage operations (for example a small supermarket) where compliance with the Food Hygiene Regulations is to be demonstrated. A variety of ancillary control equipment may be in use in such installations, each with its own specific requirements in terms of interfacing and monitoring, and m� can be configured to work in such an environment.

Designed for operational simplicity, the system once configured can display the status of each input point in turn with the occurrence of any fault condition indicated immediately by means of audible and visual alarms. Further details on any aspect of the operation of the installation are available via the key pad. In addition there is the ability for authorised personnel to make adjustments to the control and/or monitoring settings. Historical data is stored within the system and may be viewed or printed on a regular basis. The data is accessible both on and off-site via the external modem connection and alarm calls can also be generated if required.

The following sections provide a description of m�, and the remainder of the manual provides further detail on the configuration, operation, and maintenance of the system. It is recommended that the appropriate part(s) are studied before any attempt is made to use the system.

ValidityThis manual was made in 10 - �007 and applies to m� - Dual Comms with software version 3.11.

Safety

To prevent accidents arising from improper handling, installation or operation, please read this manual carefully.

4 Manual RS.8A.N5.0� © Danfoss 10-�007 m� Version 3.11

System Overview The m� consists of a central monitoring unit which can monitor up to 16 local sensors or inputs which are usually located adjacent to the equipment in question for example specific refrigerated areas (chiller cabinets, freezers, cold rooms), plant rooms or gas detectors, up to 99 EKC - controllers and 3� standard RS485 connections (1�8 1/4 loads) via the third party bus. The precise layout and configuration of these sensors and controllers is specific to each installation, and it is not necessary for a typical operator to be familiar with the operation of the sensors.

The m� provides audio and visual alarms whenever an input exceeds its pre-set alarm levels. For night operation, the system can be pre-set to dial-out using a digital dialler or via a modem whenever an alarm occurs.

Security is provided by having passcode access to the protected settings. In the case of mains failure, an alarm is triggered after a delay. The system can be pre-set to dial-out to an external telephone number if required. The m� will always FAIL SAFE (except for modem dailout).

The unit is provided with battery backup to continue historical logging during a power failure. In this case, the display backlight will switch off but the display will keep running. When an alarm occurs, the alarm siren and the red flashing backlight will still operate. The backlight will flash red, once every 5 seconds until the alarm is muted.

Note: When a mains failure lasts longer than 1 hour, the unit will cease historical logging and stop alarm checking. However, all existing historical readings remain in memory and are not lost.

The m� can monitor up to a maximum of 99 points, including up to 99 EKC - controllers, and or an additional 3� standard RS485 connections (1�8 1/4 loads) via the third party protocol.

If hard copy details of the monitor readings is required, a parallel printer port is provided which can be connected to an Epson compatible parallel printer.

An RS�3� serial interface via a 9-way ‘D’ type connector is provided which allows either a directly connected IBM compatible Personal Computer (PC) or a Minitel to be connected for operational and configuration purposes or to allow connection to a modem.

If a PC is connected either directly or via the modem, the alarms and monitor readings can be read and the set-up details can be changed remotely, using Danfoss Central Station software (refer to manual RS.8C.G for more information).

This manual will simply cover the configuration and use of the m� in monitoring and controlling a refrigeration installation.

Operation via the Key Pad

Point Overview To view the status of all the points at the same time, select the Point Overview option from the Main Menu. The Point Overview screen is displayed. This screen shows each activated point as one of the following icons, depending on the point condition.

- active point in normal condition - an inhibited point

- active point in an alarm condition - a point in defrost

- a point in defrost pulldown

Note: If there are more than �0 points in the system extra lines of points will be displayed underneath the first �0 points (up to a maximum of 99 points).

To select a point, the cursor box can be positioned around a point symbol by using the ‘ ‘ or ‘ ‘ keys. As each point is selected the point number and its current status/temperature is displayed in the window on the right hand side of the screen.When the Overview Scan mode is selected, the cursor will cycle round all the activated points in turn, pausing for 3 seconds on each one so that the current status may be read.

To display more details of a particular point, position the cursor box around the point required and press ‘↵’. The Point Detail screen will be displayed.

Note: If a point has a local offset applied to it, this will be indicated by the

presence of the offset icon at the left of the Point Readout window.

To continuously view the status of a single point, either select the Point Detail option from the Main Menu or select a point on the Point Overview and press ‘↵’. The Point Detail screen is displayed.Use the ‘ ’ key to select the next point or the ‘ ’ key to select the previous point. The point number is displayed in the upper left-hand corner of the screen and the current status is displayed in large text in the centre of the screen. The text and symbols displayed in the window on the right hand side of the screen are as follows:

Indicates the upper alarm limit setting. When the of the symbol is scrolling, it indicates that the upper alarm limit has been exceeded.

Indicates the alarm delay in minutes. When the hand of the clock rotates, it indicates that the point is in the alarm condition and the delay has not yet expired.

Indicates the lower alarm limit setting. When the part of the symbol is scrolling, it indicates that the lower alarm limit has been exceeded.

Indicates the input point type.

this indicates whether the point has been setup for 'Local' or 'Remote' alarms.

- Local - alarms are raised based on m� alarm settings.

- Remote - alarms are raised based on controller alarm settings.

Point Detail


Inhibiting a Point

Point Offset

This area also displays 'inhibit', 'defrost' and 'pulldown' icons, if the point has been setup for 'Local'.

- an inhibited point.

- a point in inhibit pulldown.

- a point in defrost.

- a point in defrost pulldown.

Note: If a point has a local offset applied to it, this will be indicated by the

presence of the offset icon located under the units indicator.When the Detail Scan mode is selected, the display will cycle through all the activated points in turn pausing for 3 seconds on each one so that the current status may be read.Press either the ‘ ’ key or the ‘ ’ key to return to the Main Menu or the ‘ ’ key to display the historical graph data.

To inhibit a point so that it cannot create an alarm, select the required point and press ‘↵’. The Confirm Inhibit Yes/No message is displayed. Use the ‘ ’ or ‘ ’ key to toggle the answer and press ‘↵’. When a point is inhibited a symbol is displayed alongside the point type. To uninhibit a point repeat the operation.

If the alarm condition is exceeded on an inhibited point (i.e. Pull-down), then the animated pull-down arrows will be displayed next to the inhibit symbol .The inhibit function can be password protected. This can be configured by accessing the 'Passcode Setup' screen.

Any points on the m� can have an offset applied to the displayed readings to compensate for cable runs loss etc. These offsets are point specific and may only be defined from the m� keypad, although their value is readable when accessing the unit remotely. Under normal circumstances these offsets (if required) will be entered at installation and should only be modified by Danfoss

personnel. Any point which has an offset active will display the offset icon on both the Point Detail and Point Overview screens.

In the Point Detail screen, pressing the ‘ ’ key displays the Print Range option box. Use the ‘ ’, ‘ , ‘ ’ and ‘ ’ keys to enter the required value and the ‘↵’ key

to move through each field. Press the ‘ ’ key and the Printing in Operation screen is displayed and the data is sent to the printer.

Single Point Log Printout


The format of the printout will be as shown:

To display an instant graph of the currently selected point, from the Point Detail screen, press the ‘ ’ key. The chart is then displayed.The default time scale for the data displayed depends on the sample rate set. For example, a sample rate of 15 minutes will give a default time scale of 1 day.

To view historic data, press the ‘ ’ or ‘ ’ keys to page the graphic screens (with no overlap). Pressing the ‘ ’ or ' ' keys scroll through each of the points displaying the data graphs. Press the ‘↵’ to bring up the cursor, this can then be moved along left or right displaying the reading and time for the cursor position in the top right hand corner of the screen. In addition the screen will page left or right when the cursor reaches the end of the display. To zoom in or out press the ' ' or ' ' keys, this will display the following time spans:

45 mins 1� hours 4 weeks 1.5 hours 1 day 1� weeks 3 hours 3.5 days 11 months 6 hours 1 week

To exit the zoom facility, remove the graph cursor by pressing '↵' again. Pressing the ' ' key will then take you back to the Point Detail screen.

When a graph is displayed on the screen, pressing the ' ' key dumps the graph to a directly connected printer (cursor must be removed first).

A pulsed input function is available for accepting pulses from a power meter. The pulsed input is displayed as shown which includes two values. The large value is the ‘Rate’ and indicates either current kW usage (Const) once per minute or the ‘Peak’ kW usage within the current sample period.If the ‘Rate’ current usage is displayed, this value will vary with the actual energy consumed within the last minute. If the ‘Peak’ usage is displayed, this will only change if the usage in the last minute was greater than any other minute in the sample period - hence it will show the highest or ‘Peak’ value. The ‘Rate’ value is stored by the m� and will be displayed in the graph associated with this point.

The second smaller value will show the accumulated kWh used within the current sample period. This value will increase over the sample period then reset to zero at the end.

The ‘Pulsed Icon’ to the left of the display will change from to each time a pulse is being received.

Pulsed Input


In normal operation if no scan mode is selected, the m� will revert to the Point Overview screen.When one or more alarms have been raised, the built-in siren will sound, the backlight will flash red and the point(s) in alarm will pulse. If a parallel printer is connected, the time, status and point details of the alarm will be printed.If the ‘ ’ key is not pressed within the programmed time setting, the dial-out relay can be programmed to automatically activate, sending a signal to the dial-out equipment/security system if it is connected.

To stop the siren sounding and the red backlight flashing, press the ‘ ’ key. Check what the problem is by selecting the Point Detail screen for the point in alarm and noting its present status and alarm settings. The fault will need to be found and rectified before the alarm can be successfully cleared.If there appears to be no problem, it could be that the fault has ‘cleared itself’ (e.g. the temperature has since returned to an acceptable level). In this case, the point will stop pulsing. If there are no further faults on other points, the alarm status will be cleared.

To display the Main Menu, press the ‘ ’ key (repeat if necessary). To select an option from the Main Menu, use the ‘ ’ or ‘ ’ key to position the highlight over the required option and press ‘↵’ or ‘ ’.

Configuring the System via the Key Pad

Entering Characters in Edit Fields There are two types of character sets that are used in the m� depending on which edit field has been selected:

Full Character Set This is used in most of the edit fields. When the edit field has been selected, the characters within the set can be cycled through using the ‘ ’ or ‘ ’ keys. If the ‘ ’ key is pressed first, it will start at ‘A’ and go forward through the character set. If the ‘ ’ key is pressed first, it will start at ‘z’ and go backwards through the character set.

When a character has been selected, press either ‘ ’ to move to the next space or ‘↵’ to move to the next edit field.

Alphanumeric Character Set If the ‘ ’ key is pressed first, it will start at ‘0’ and go forward through the character set. If the ‘ key is pressed first, it will start at ‘z’ and go backwards through the character set.

By pressing the ‘ ’ or ‘ ’ keys, the field is incremented or decremented. By pressing the ‘ ’ or ‘ ’ keys you can skip across the unit fields to make entering larger numbers easier.

If your language uses Diacritics (accented characters), the m� provides the facility to enter these both from the local keypad and remotely via PC. This facility is language sensitive such that only Diacritics which are relevant to the language active on the unit are available. The method of entry is to select a base character as normal and then add the required accent, e.g. in French if an ‘é’ is required the procedure is to first select ‘e’ as described above, then enter Diacritic mode and select the acute accent ´. To enter a Diacritic mode on a

suitable character, hold down the ‘ ’ like a shift key and press the ‘ ’ key once. This will add the first available accent to your character, any more which are available can then be selected by pressing the ‘ and ‘ ’ keys together. When the required accent is displayed, simply moving on to the next character stores this and cancels the Diacritic mode. If you move the cursor onto an already accented character, the unit will automatically enter Diacritic mode allowing you to change the accent. Diacritic mode may be manually cancelled by pressing the

‘ ’ and ‘ ’ once more.

To configure the system via the key pad, select the Setup Menu option from the Main Menu.

To change any of the configuration information via the keypad, you must first enter the correct password. The default passcode is �91. However, this may have been changed to a passcode which is site specific.

Use the ‘ ’ or ‘ ’ keys to cycle through the character list to the required value and the ‘ ’ or ‘ ’ key to move the cursor left or right respectively. Press the ‘↵’ key to move onto the next field.

This field refers to the overall size of the graph temperature range. Entering zero selects the auto-scale option. Alternatively, enter the required range. The range goes from the lowest graph point (Y Base value) to the highest graph point. Use the ‘ ’, ‘ ’, ‘ ’ or '‘ ’ keys to enter the required value.

This field refers to the lowest value the graph will show. This value should be slightly lower than you expect the temperature to drop to. If auto scale in the Y axis is selected this value is not used. Use the ‘ ’, ‘ ’, ‘ ’ or '‘ ’ keys to enter the required value.

These values are used exclusively in conjunction with a standard 4-�0 mA input which can represent pressure, humidity, level, flow rate, or any other variable which can produce a 4-�0 mA output.

The value for the upper and lower limits can therefore represent % (RH), PPM, bar or psi etc., depending on the medium being measured. A numerical value for 4 mA (lower limit) and �0 mA (higher limit) is entered, and the m� automatically scales the input for a figure proportional to the measurement. Use the ‘ ’, ‘ ’, ‘ ’ and ‘ ’ keys to enter the required value.

Finally, press ‘ ’ to return to the Setup Menu.

To setup the pulsed input, from the Point Setup menu select ‘PLS’ in the Point Type field. All the remaining fields in ‘Screen 1’ of the Point Setup are the same as normal.

In ‘Screen �’ of the Point Setup there are a couple of extra fields added. These are as explained below:

This field is to set either the ‘Constant’ or ‘Peak’ value to be used as explained previously.

This field is to set the amount of pulses that is to be recieved from the power meter per kWh.

If the Pulsed Input is being setup via Danfoss Central Station software, there is an extra field named ‘Export’ that can be used.This field is set if the points data is to be exported to AKM format for analysis by Power Focus or similar software.

The m� Pulsed Input requires a volt free contact or an open collector and the pusle width must be a minimum of 80 mS.

The Pulsed Input will operate with either PT1000 or Thermistor m� input boards.

The resolution of the pulse data depends on the sample rate of the m� – the longer the sample rate, the greater the resolution, as well as the resolution of the power meter being used.

For example: If the power meter outputs five pulses for every Kilo Watt Hour (KWh) and with a current usage of 6 KW.

With an m� sample rate of 3 minutes:

1or2pulsesreceivedper3minuteinterval((5pulsesx6KWh)/60minutes)x3minutes=1.51pulsex0.2KWx20(for1hour)=4KW2pulsesx0.2KWx20(for1hour)=8KW

Resolutionis0.8.Valuescouldbe0,0.8,1.6,2.4,3.2,4.0,4.8,5.6,6.4etc.

With the Peak option, the sample rate is 1 minute (though the storage rate is whatever the m� is set for) which gives a very poor graph resolution, this makes the Peak value very inaccurate unless the power meter outputs many pulses per KWh.

This option allows the coordinated defrost setup of a network of EKC controllers. From the Setup Menu, select the Defrost Schedule option.

Use the ‘↵’ to highlight the field to be modified. Use the ‘ ’ and ‘ ’ keys to scroll through the character or options list and the ‘ ’ and ‘ ’ keys to move the cursor left or right respectively.

Set the values as follows:

Number Set this to the point number required for the defrost schedule.

Name Enter the name required for this defrost schedule (this is the point name).

Mode Select either ‘Master’ or ‘Follows’ depending on whether the controller being setup is a ‘Main’ or ‘Secondary’ controller. If ‘Master’ has been set, then the next field becomes active in which the controllers address needs to be entered.Coordinate This field only becomes active if ‘Master’ is selected in the previous field. Select either ‘Yes’ or ‘No’ depending on if the ‘Secondary’ controllers information is to be used for end of defrost control.

For example, on the Alarm Action Setup screen illustrated, Alarm Actions 1, � and 7 will always trigger Relay 1.Note: The alarm action number is set for each point in turn so that pre-determined actions occur when that point is in alarm.

Use this field to specify the delay time in seconds before the device is activated by an alarm. For example, if the site is manned, a delay of say 10 minutes could be entered giving the staff time to respond to the alarm before the dial-out operation occurs. Use ‘ ’ or ‘ ’ keys to cycle through the character list and the ‘ ‘ or ‘ ‘ key to move the cursor left or right respectively.

For RelaysUse this field to specify the time in seconds that the relay will be activated.

Note:-Entering “999” will activate the relay until the ‘clear on’ condition occurs.

For ModemsUse this field to specify the time in seconds between an unsuccessful call and the next attempt.

Use this field to specify the clear alarm operation as follows:

NoACK Clears the alarm condition when no new or no acknowledged alarms are present.

Mute Clear the alarm when the Mute key is pressed.

Time Clear the alarm when the time specified under Duration has expired.

MuteR When in alarm, if the 'Mute' key is pressed then the relay will open. If after the 'Duration Time' the alarm is still present, then the relay will close again. If the 'Mute' key is not pressed, then the relay will open after the 'Duration Time' for 10 seconds. This will continue until the input triggering the alarm has been reset.

ClrR Same as above except for pressing the 'Mute' key will not open the relay.

Note: It is not recommended that ‘999’ is specified with ‘Time’ as the system would have to be switched off to clear the alarm.


Use this option to set the modem dialout settings. From the Setup Menu, select Modem Dialout Options.

When connected to a modem, the m� is able to make telephone calls to up to five pre-programmed numbers whenever an alarm is detected. Alternatively, individual alarms detected for a particular point can be routed to a particular telephone number. It can also call a radio pager to alert a duty engineer. Three types of pager can be supported - Tone only, Numeric and Alphanumeric. The message that is sent can also be defined.

Note: Support for the TAP pager protocol is available in UK, France, Switzerland and Scandinavia.

Use the ‘ ’ or ‘ ’ keys to cycle through the dialout numbers and complete the fields for each device as described below:

Use this field to specify the type of device which is connected to the specified telephone number. The options are as follows:

NO DIAL Inhibits the output.

GSM SMS Indicates that a RS�3�/GSM modem device is connected. Sends text messages to a GSM mobile phone and receives messages. For information on this feature refer to document Functional Description RC.8A.M.

DOWNLOAD Indicates that a computer is connected (directly or remotely). Sends the alarm message using Woodley Xmodem Alarm protocol. If the line is busy, the telephone number will be dialled up to four times (8 bit, No Parity, 1 Stop Bit).

AKM Same as above, except that dialout attempts will continue; after every 10 attempts will reset the alarm relay. Note:Modem must be wired in conjunction with the alarm relay (refer to appendix A). BEEPER Indicates that a beeper type pager is connected. The system dials the appropriate telephone number and then disconnects. As there is no security associated with this option, the telephone number is always dialled twice unless the busy tone is received. MESSAGE7 Indicates that a 7 bit modem is connected with a printer attached. (7 bit, Even Parity, 1 Stop Bit) (normally used in France). MESSAGE8 Indicates that an 8 bit modem is connected with a printer attached. (8 bit, No Parity, 1 Stop Bit) (normally used in UK). PAGER7S Indicates that a TAP 7 bit protocol pager is connected which can display a message. The message sent is defined on the Pager Info line (7 bit, Even Parity, 1 Stop Bit).

PAGER7M Identical to PAGER7S but sends message up to 4 times.

PAGER8S Indicates that a TAP 8 bit protocol pager is connected which can display a message. The message sent is defined on the Pager Info line (8 bit, No Parity, 1 Stop Bit).

PAGER8M Identical to PAGER8S but sends message multiple times.

Enter the appropriate telephone numbers for each of the devices used. If a comma ‘,’ is inserted before the number, a delay of between � and 4 seconds will be inserted between the modem picking up the line and dialling. If a ‘w’ is inserted before the number, the modem will wait for the secondary tone before dialling.

Probe curves can be used to define the relationship between input Resistance or Current values and engineering units (e.g. Temperature, Pressure etc.). For example, probe curves could be used for a gas detection sensor.

This option allows you to define such a relationship for 4 separate curve types using information about Resistance/Current to Output Value transfer characteristic of a given probe, supplied by probe manufacturers. From the Set-up Menu, select the Define Probe Curves option. The Curve Table Set-up screen is displayed. There are 4 curve tables available - Cf1, Cf�, Cf3 and Cf4. Use the ‘ ’ or ‘ ’ keys to cycle through the curves until the correct type is displayed.

The table can have up to 1� break points to define the Curve Table relationship. Each of these break points will have a corresponding Input and Output value which must be entered by the user. The Output value will be the reading which should be displayed on the Point Detail /Overview Screen for a given Resistance/Current value. The Input Value will be an Internally Scaled version of that Resistance/Current Input value.

Below are explanations of each fields displayed for defining the curve tables:

Con 1 as This field is for selecting either 'RESISTOR' or 'CURRENT' depending on the type of probe being used.

To use = This field displays the Internally Scaled version of a Resistance/Current connected across the unit's Input 1 and COM terminals. This value will be in the range of 0 to 9999. This readout is used to determine what to put in the Input field when setting up the Curve Table.

Converted = This field displays the result of applying the selected Curve table function to the 'To use =' value being displayed. Thus when no Break Input & Output values have been entered, this will give an out of range reading (SC/OC). As a Curve Table is built up, however, it will start to show the Output value corresponding to whatever the Resistance/Current connected across Input 1.

Defining the Probe Curves

Pager Info


Curve This field is used to select 1 of the 4 curve tables (Cf1 - Cf4).

Break This field is used to select the break point being set up on the curve (1 - 1�).

Input This field is for the Internally Scaled input value to be used at the break point selected. The 'To use =' value can be copied into this field by pressing ' ' and ' ' together. This field has a range of between 0 and 9999.

Output This field is for the Output value at the Break Point/ Input value selected. This has a range of between -999.9 and 999.9.

The table should be completed so that the Input readings increase in value. Any reading below the first value or above the last value will return out of range Output Values (OC/SC).In order to set up a Table you will require either a Resistance box (for resistance probes) or a Current Source (for Current Probes) plus the manufacturer's data defining the Input/Output relationship of the probe. The method is described for a Resistance probe, but it is the same for the Current case except that it is necessary to put the Input 1 link in the 4-�0 mA position before starting.

1. Select (up to) 1� Output (Resistance) values from the manufacturer's data sheet which correspond to Input (e.g. Temperature) values in the range you wish to measure. For maximum accuracy these points should be distributed evenly across the required range.

�. Connect the Resistance Box across the Input No. 1 and C terminals of the unit and set it to the lowest of your selected Output values. When you do this you should see a value appear in the 'To use =' field. This is the Internally Scaled version of the resistance you have connected. Set the Break field to 1 and then go to the Input field.

3. Next either manually enter the value displayed in the 'To use =' field, or press the ‘ ‘ and ‘ ‘ keys together to copy it to the Input field.

4. Move to the Output field and enter the Output (e.g. Temperature) value from your probe data corresponding to the Resistance value you set.

5. Move the Edit Box to the Break field again and increase its value by 1, which will clear the Input and Output fields.

6. Set your next chosen Resistance value from the probe data and, when the 'To use =' value has stabilised, repeat from step 3 until all your points have been entered.

Once all points have been entered, you can vary the resistance connected to Input 1 and observe the effect in the Converted field. For a given resistance, this value should now be the same as that shown in the manufacturer's probe data.

For 4-�0 mA inputs the 'Input type' must be set to 'CURRENT', then the Input/Output fields will change to 4 mA/�0 mA. The curve table can now be set up. For example, if a pressure sensor was being used which produced 4 mA at 0.1 bar and �0 mA at 30 bar, then simply add 0.1 to the 4 mA field and 30 to the �0 mA filed. Ensure the point set-up and jumper link on the input terminal is set to 4-�0 mA.

'AKM' Call Type

Background The Danfoss AKM has been updated to allow it to receive alarms from m� units. However the m� alarm dialout procedure differs from the Danfoss Gateway in that it is not as tolerant of faulty telecommunication equipment. The m� would make repeated calls to try to transmit the alarm message up to a maximum of 8. This conformed to the current telecommunication regulations when the procedure as defined.AKM will continue to try to transmit the alarm indefinitely. It can also control the power to the modem using one of it relays. It does this after ten failed attempts to dial-out and every 6 hours.The 'AKM' call type has been created to mimmic the same dialout as the AKM.

The m� has two relays that are normally used for alarm indication. The Relay � (REP ALARM) can be used to control the modem power. The Relay is rated at �4V 1A max, so the low voltage power after the mains transformer must be switched. Mains voltage MUST NOT be connected to this relay.

Set this field to either 'RTD' (for temperature monitoring) or '4�0' (for 4-�0mA inputs).

With the 'Type' field highlighted, press the ' ' key to display the second point setup screen.

Set this field to 'T-PARTY'.

Set this field to the same address that has been set on the m�+.

Set this field to the type of input being used by the m�+ unit.Use the ‘ ’and ‘ ’ keys to cycle through the valid options as follows: · RESISTOR Resistor input.· CURRENT 4 - �0 mA input. · DIGITAL Normally open or normally closed contacts (Contact).· PT1000 PT1000

Set this field to the input number being used on the m�+ unit for monitoring.

EKC measurements and setup

ConceptThe m� display can display data from individual controllers. Data is uploaded to m� via data com-munication.The following can be displayed, depending on the type of controller and what is being regulated:

The point number w

Supplementary text that can be added to the point number

Indicates the upper alarm limit setting. When the of the symbol is scrolling, it indicates that the upper alarm limit has been exceeded.

A waveIndicates the set point for the EKC controller

Indicates the lower alarm limit setting. When the part of the symbol is scrolling, it indicates that the lower alarm limit has been exceeded.

Primary meas-urement from the controller. This shows the air temperature.

For a pack con-trol it could be: P0bar

- Remote - alarms are based on controller settings. Alarm limits will be determined by the external controller.

Some alarm limits are set as absolute values, others as a difference to the set point. See controller data.

Regulation status is shown by means of icons, e.g.:

- cooling

- defrost

- fans on

- compressors on

Secondary measure-ment from the controller. This shows the de-frost temperature.

For a pack control it could be: Pcbar

Each controller must have an address set using the controller’s menu system.

Network address o03 1-99

Service-pin message o04 ON

Setup EKC controllersm� can receive signals from up to 99 EKC controllers. (Although max. 99 measurements in all to one m�.)The data communication cable on RS485 (LON) must fulfil the requirements described in the separate document: RC8AC.

AddressesEach EKC controller must have an address set in its menu system. This address must then be sent via data communication to the m� unit. This is done us-ing a setting in the EKC controller. When m� receives the address, it will first use the address number as a point number, so that the two numbers are the same. BUT this is only the case if the point has not already been defined for the other side (another EKC controller or a direct point). If it has already been used, the existing setting will be retained and the last one entered will not be used.

The following controllers can be connected to an m� unit:EKC �01, �01C, �01 dbl. thermostat, EKC 301EKC �0� version A, B, C, DEKC 331EKC 331TEKC 531D1 version 1.36 application 1 (1.361)AK-PC 530 version 1.36 application 1 (1.361)

Do not use the same address for several EKC controllers and do not use an address number that has already been used as a point number.

Sequence:1. Connect m� and the EKC controllers using a data communication cable�. Switch on m�3. Switch on the first EKC controller

a. Set the menu “o03” b. Set the menu “o04”

4. Repeat point 3 for all controllers on the data communication5. Continue setup in m�. See page 33.

Shown in the table below is the operation for logging a EKC controller onto a m� system.

The symbols for pushing of buttons have the following meanings:

Push the upper button Push the lower button

Push both buttons simultaneously

When a EKC controller is logged on to a m� system, whatever the controllers address is parameter (o03) will automatically be assigned as the point number on the m�. This will include overwriting any previous settings set to that point number.Ensure before logging a EKC controller onto a m� system, that the address set is available in the m�. If not available then change the address on the controller.

Choice of measurements to be displayed as pri-mary and secondary:

Select the menu: Setup Menu \ Point Setup

Number: Select the point number (i.e. address number of EKC)

Type: Select “EKC”Alarms: Will always be “Remote”. The alarm limits

for the controller will be used.

Other settings are those normally used for m�.

Next menu

Press and hold down the ‘Enter’ key until the second Point Setup screen is displayed or press the ' ' in the point type field.

Input Source: Select “ECHELON” (= data communication)Primary Temp: Used to select the parameter to be displayed as primary Secndary Temp: Used to select the parameter to be displayed as secondary

Other settings are those normally used for m�.


Alarm Action Setup

When an alarm occurs, a number of settings will determine which func-tions are to be activated. The definition of each point includes assigning an action number from 1 to 15.The latter menu display is used to determine which functions will be activated by the action number in question.

Pressing “Mute” results in alarm reset 1 2 3 4 5 6 7 8

Pressing “Mute” results in alarm reset and alarm reset for AKM 9 10 11

As above, but also transmits alarm status 0 to AKM, if the alarm turns itself off
