1 GENERAL DESCRIPTION The XJ500 is a monitoring system which is specific for the control of all data, alarms and the functioning status of refrigeration plants, in food preparation and food conservation processes and also in distribution. This device can communicate with all the Dixell instruments with serial port both DixBUS and ModBUS protocol communication. THE APPLICATION The main characteristic of the XJ500 is that the same unit can work as a “Stand alone system” or be connected to a Personal Computer so it can be easily installed both in small shops and big markets. Typical applications are: food plants, for medical use (blood banks, medicine stores, etc), industrial processes, supermarkets, cold rooms, catering, fast food or normal restaurants, gasoline stations and convenience stores. THE DATA The XJ500 unit receives input data coming from Dixell instruments provided with serial output. For each instrument the monitoring program allows the reading and storage the following information: probe values, alarm and functioning status. It can be interfaced to refrigeration instruments, step controllers, temperature humidity and pressure units with Dixell serial output. THE RECORDING Basically the XJ500 was created to record room temperature, alarm status and functioning status of instruments connected to RS485 line for a year with a sampling time of 15 minutes in order to comply with the European Community standards for food controlling processes 89/108 CEE, 92/1 CEE, 92/2 CEE and 93/43 CEE. The unit can also manage other signals like “Bar” or “Psi” for pressure or “Rh” and any other unit of measurements interfaced through 4/20mA signals. THE ALARMS The XJ manages the “General alarms” defined as probe failure, high and low alarms, digital input activation and the “System alarms” defined as data memory overflow, “no link” with an instrument, “no link” with the RS485 and “no link” with the printer. When an alarm condition is detected, the unit can manage the local print and the fax messages. PRINT The temperature and alarm reports can be printed by enabling either the Automatic print or the Manual print. The printed report shows the temperatures, the interval time of the sampling and the alarms. The special HACCP function allows the user to print automatically, at a desired interval of time, the instant measured temperature. THE FAX/MODEM XJ500 Automatically sends fax or SMS messages in case of alarm situations to a service centre or to a selected telephone number. A list of 15 numbers is programmable by the User. THE INTERACTIVE FUNCTIONS The XJ500 is provided with manual and time-based procedures to manage the synchronised defrost of instruments and execute daily or weekly cycles with the auxiliary relays such as the blind and the light controls. The programming timers of each auxiliary relay and defrost, allow the User to set 90 steps made of on/off operations, 1 operation every 10 minutes. THE SYSTEM PROTECTIONS Access to programming can be protected by activating one of the four available passwords DATA RECORDING Through the RS485 line, the information coming from DIXELL instruments are collected by the XJ500 unit, which logs them. For each instrument, the User can decide what data has to be stored, such as: probe values, probe failure, high and low alarms and output status (defrost, comp. status etc.). The recording flow is a FIFO format (First In, First out) into a Flash memory that ensures a high speed and big data capacity. Before reaching maximum storage space, the XJ500 actives alarm signals. In this case the data should be Down-loaded so it is saved.


1592010001 XJ500 v3_4 GB r1.1 16_04_2003.doc XJ500 Pag.7 / 47

MANAGEMENT OF THE RECORDED DATA It is possible to display all the data directly through the XJ500 LCD display or through the printed reports. The manual print allows the User to print the data available in the memory, the report is selectable in a range of times programmable by the User. In order to have a historical file the unit is also capable of executing daily or weekly prints. THE XView TOOL SOFTWARE Through this tool software it is possible to manage the same programming functions of the XJ500 from a local or remote Personal Computer in order to make the setup procedure easier. The tool software also allows to down load the recordings, executed by the XJ500, to display and print them in table or graph format. SERIAL OUTPUT RS232 MODBUS-RTU The XJ500 will maintain all the characteristics of the previous series, independently recording data and system diagnostics even in mixed networks in which DixBUS and ModBUS protocol instruments are used. Moreover RS232 serial output allows all system data to be transferred to a main ModBUS compatible monitoring system, in this way acting as a gateway.

2 THINGS TO KNOW BEFORE THE INSTALLATION THE UNIT As default the unit is based on 2 Mbyte of memory suitable for recording the data of the first probe (usually the room probe) of 12 instruments for a year. The interval time is defined in 15 minutes. The User can modify this default parameter programming or expand the memory up to 10 Mb of memory. THE PACKAGING Inside the packaging you will find: 1) the XJ500 unit. 2) the instruction manual. 3) 3 disks with the “XVIEW” software

PART FUNCTION CODE NUMBER Memory card of 8Mb Expansion flash memory J0VZZZZ100 RS232 LAP LINK cable Connection cable for PC, 1.8mt, 9 pin, female DD300000 10 Centronic Cable Connection cable for printer DD400000 10

OPTIONAL You can require: A) the LAP LINK cable for the connection to the Personal Computer (not suitable to connect the modem); B) the printer XJ50PR with 40 columns; C) the card memory of 8 Mb. THE FAX MODEM DEVICE Be sure that the modem type is CLASS 1 compatible, V21/V29, G3. THE GMS MODEM DEVICE The SMS modem to be used with XJ500 is the SIEMENS TC35 terminal. Dixell offer a kit, named TC35-KIT, which includes the modem, the power supply unit, the aerial with relevant cable and the connection cable to XJ500. THE PRINTER We suggest the use of a FX EPSON emulation, IMB emulation and HP emulation printers. THE TOOL PROGRAM The “XVIEW” runs under Windows 95/98 and Windows NT platforms.


1592010001 XJ500 v3_4 GB r1.1 16_04_2003.doc XJ500 Pag.8 / 47

3 THINGS REQUIRED FOR THE SYSTEM The XJ500 can be connected in three different configurations: - Without modem and without the PC; - With a modem via RS232 to send data and alarm messages; - With a local PC to manage big systems with lots of instruments.

Assure that all the Dixell instruments that have to be connected to the XJ500 supervisor system are provided with the serial output.

BEFORE STARTING THE SUPERVISOR To run the XJ500 unit read these important information: 1) A shielded cable with 3 wires must reach all the places where the instruments are fitted (eg BELDEN 8772); 2) The wires of the RS485 line must be connected with the interface modules XJRS485; 3) Each XJRS485 interface module must be connected with the corresponding instrument through the 5 pins TTL cable

supplied with the instrument itself; 4) Each instrument must be addressed with its unique number, by programming the parameters Ad2 or Adr ;(Ad1 must be

equal to 0)

THE RS485 SERIAL LINE - The cable of the RS485 line can be a three wires plus shield starting from a minimum of 0,5mm2. (e.g. BELDEN 8772) - From the office where the XJ will be installed, the cable must reach all the instruments controlled by the supervisor. - If possible keep this cable away from power lines or contactors. - It is really important not connect the cable shield to the plant electrical ground. - Draw a map of the followed path can be useful when a line check is necessary. - Do not make loops or other type of connections.

To keep balanced the RS485 the beginning and the end of line must be closed with a resistor. This resistor is already mounted inside the instruments and it can be activated by following these two different applications schemes. The XJ500 is connected at the beginning of the line:

In this case close the Jumper inside the monitoring unit and set the end of the line with a jumper on the terminals 18 - 19. These terminals are indicated on the label of XJRS485. 2) The XJ500 is connected in the middle of the line:

The jumper of the XJ500 must be removed, but to set the beginning and the end of the line it necessary to close the jumper (terminals 18 - 19) of the first and the last instrument connected.


1592010001 XJ500 v3_4 GB r1.1 16_04_2003.doc XJ500 Pag.9 / 47

3) When the last instrument in the net is with built in RS485 with 2 cables (XR100, XJA, XJP etc.) if there are problems in the serial communication it could be necessary to connect an 100ohm resistor in parallel to the serial line to keep balanced the RS485. Do not make loops in the connections

CONNECTING THE INSTRUMENT 1. Each XJRS485 interface module is provided with 3 terminals for the input / output data. 2. Decide which of the 3 wires must be connected to the “+” terminal, to the “-“ terminal and to the “Gnd”, proceed always

respecting the polarity. 3. Some series (XR100, XJA, XJP, XT/XH/XP “R” format) with serial output do not need the XJRS485.

THE TTL CONNECTION 1. Each instrument must be connected to its RS485 interface through a 5 pins TTL cable. 2. If powered with 12Vac, the instrument can be supplied directly from the terminals 7 and 8 of the XJRS485, with a

maximum power of 5VA. 3. In any case keep the TTL cable away from any power lines or any contactors. 4. The series ordered with serial output RS485, does not use the interface XJRS485 and the TTL cable. 5. In the instruments with built in RS485 with two cables must be connected the “+” and the “-“. The GND doesn’t have to

be connected.


1592010001 XJ500 v3_4 GB r1.1 16_04_2003.doc XJ500 Pag.10 / 47

SERIAL ADDRESSING OF THE INSTRUMENTS 1. Each instrument needs a unique address in order to be recognised by the XJ500. 2. This address can be programmed by the Adr parameter in the ModBUS instruments and by Ad2 parameter in the

DixBUS instrument. Ad1 must be set equal to 0 in the instruments with DixBUS protocol communication. Refer to the Installing and Operating Manual of the instrument.

3. To make the description procedure easier, it is better divide the installed instruments in categories having progressive number Adr (Ad2) for each device.

N.B. NOT USE THE 16TH INDEX

CALLING GROUPS define the allocation of the phone book number to one of the 4 calling groups. GROUP 1..4 To each groups is possible to assign up to 4 different numbers selected from the phone book. XJ500 will

send a message to all the numbers present in group 1. If none of them is available (for example they are not allowed for that particular day), it will go to group 2 and so on.

FAX AT INTERVAL Enable the sending of a Fax/SMS about the working status of XJ500; INTERVAL (OFF…24) defines the interval (in hours) between the sending of the fax/SMS. Ik set as OFF the function is

disabled. STARTING TIME (00:00…23:50) defines the hour when to send the first fax/SMS about XJ500 status. Starting from this

time, the fax/sms will be sent following the interval selected in the previous parameter. GENERAL defines the general modem features: RING NUMBER before answering (1-15); TIME DELAY BETWEEN TWO CALLS (1..15 min); NUM RETRY (0 - 3) number of retries if the line is not free. SPEED is the modem transmission speed (2400, 4800, 9600, 19200, 38400 baud).

< RECOGNISING > CHECK ADDRESS 1 DEVICE FOUND 1

Please Wait…. 6. Check the “Device Found” parameter:

The number of devices should be the same as the number of instruments connected to the RS485. If it is not equal, probably the line is interrupted or some Adr (Ad2) parameters are not properly programmed.

6. At the end of the searching each instrument has to be confirmed, an indicator shows the device progressive number

1/11:

< CONFIRMATION > ADDRESS 01 NEW MODEL XR570C PROBE(s) 2

7. The “NEW” label indicates that the instrument found is not present in the actual setup therefore push the ENTER key

to confirm it. If the “NEW” label does not appear, the instrument is still present therefore push DELETE otherwise it overwrites the existing instrument.

By pushing the EXIT key during this procedure only the confirmed devices will be saved into the memory.

If no key buttons are pressed within 40 seconds, the XJ500 exits from the programming. Only the confirmed devices will be saved into the memory.

If you need to restart a new and complete configuration, remember to REMOVE all the devices to avoid having conflicts between old and new devices.

7.3 MANUAL SEARCH OF THE INSTRUMENT This procedure allows the User to add a single instrument to the existing set-up. In this case it is necessary to know the Adr (Ad2) parameter of the instrument in order to set the Family and Device with the right values.

< DEVICE SETUP > ADR 00

set the two values and then push ENTER to start the search.

7.3.1 DELETE THE INSTRUMENT To remove the instruments, enter the USER MENU - SETUP - DEVICES - REMOVE menu select SINGLE and push ENTER. If you select SINGLE (it removes only one device at time), you will be required to select it from the list of available devices actually in the setup. By selecting ALL, be careful because you will remove the complete setup.

PRINT SYSTEM STATUS REC

The XJ500 unit is now recording all the data read by the RS485 line.

REMEMBER that the XJ records the data which have been enabled under the CONFIGURE menu and under the ACQUISITION menu. The XJ500 records the data only if the SYSTEM STATUS parameter is set to “REC”.


1592010001 XJ500 v3_4 GB r1.1 16_04_2003.doc XJ500 Pag.24 / 47

7.6 RECORDING STOP

7.6.1 POWER FAILURE In case of power failure the unit stops immediately the recording. However before turning completely off, the XJ500 records the “Black-Out” alarm message. After the power supply restarts, the recording file is verified; the time passed between the last and the new recordings is considered as Black-out duration time. During the black-out event the unit does not record any data and when the power supply is restored, the recordings restart automatically. In this situation both the instrument and the modem are switched off. During this situation the Alarm Relay contacts are closed to signal the alarm event.

REMEMBER that the internal battery of the clock lasts maximum 12 hours without power supply. After this time the unit needs to set the clock parameters.

If you intend to extend the time duration of the clock battery, it is possible to connect a 12Vdc external battery to the back-up terminals (see chapter 4). To avoid turning off the unit, it is necessary to connect an external Back-up system which supplies both the XJ500 and the modem when the supply fails.

7.6.2 WHEN THE RECORDINGS ARE MANUALLY STOPPED When somebody stops manually the recordings by means the parameter SYSTEM STATUS = OFF, the XJ500 saves the date, the time and the “STOP” warning message. This same message will be recorded even in the case that the recordings are stopped from a remote connection executed by the XVIEW program.

8 VIEW This menu allows the User to display and verify the data and the alarms which are available instantaneously on the RS485 line (ACTUAL), or those that have already been recorded (FROM ARCHIVE). The ACTUAL menu is enabled only if SYSTEM STATUS parameter is not set to OFF.

10 ALARM MANAGEMENT

10.1 ALARM DEFINITIONS The Historical Alarm Archive contains the recordings executed with the TIME INTERVAL parameter. This file can be consulted in any time by entering the VIEW – ALARM – FROM ARCHIVE menu. The information contained in this archive can be used also several months after the date of the recording. The Event Alarm Archive contains the last 100 alarms with the full description of the event such as: start and stop dates, origin of the alarm, probe temperature, setpoint of the instrument. This alarm information can be showed at any time just pushing ENTER directly of the keyboard when the XJ500 is not under the key MENU activity. This is a FIFO file format and, after 100 alarm events, the first recording will be pushed out from the archive. The information contained in this archive are the same used to send the fax alarm message and to print alarm report.

THINGS YOU MUST KNOW Enable the whole alarm management under: USER MENU –SETUP - ALARM - ALARM CONTROL (default not enabled). Check the alarm management of a single instrument under USER MENU – SETUP - DEVICE(S) – CONFIGURE - SAVE ALARM.

The alarm print out can be enabled under USER MENU –SETUP - ALARM – PRINT ENABLE.

Enable the alarm fax transmission under: USER MENU –SETUP - ALARM - TX FAX ENABLE. After activating the SYSTEM STATUS parameter (ACQ or REC), no alarms are detected for the time set in TIME ESC PO parameter value. During an alarm situation with the "DATA" led turned on, do not overload the unit with manual prints or other operations (the XJ500 is trying to print or send a fax).

The alarm relay stays on for all the alarm duration time and it can never be stopped.

10.2 SHOW ALARM EVENTS When an alarm occurs the XJ500 displays a warning message, the buzzer is on and the alarm relay contacts are closed.

10.2.1 HOW TO VIEW THE ALARM EVENTS When there is an alarm condition, press the ENTER button to show the list of the last 100 alarm events. If you are working under the MENU key activity, push the EXIT key to return to the main display. 1. Push ENTER key to show the last 100 events:

10.4 VIEW THE ACTUAL ALARMS Under USER MENU – VIEW – ALARM – ACTUAL the User can verify the exact origin of the problem and the number of devices in alarm:

< ACTUAL ALARM > No Name 1/11

Pb1: HIGH Pb2: -14.3

If no alarm is present this menu does not shows any device.

10.5 HOW TO SHOW THE ALARM EVENTS AFTER SOME MONTHS FROM THE BEGIN OF THE RECORDINGS

See the VIEW – ALARM – FROM ARCHIVE cap 8.3. IMPORTANT NOTE

During a Manual or Automatic print the alarm warning procedure will be postponed until the previous printing or fax queue is finished. In any case the alarm information is stored.

If the alarm duration is lower than the sampling interval time STORE INTERVAL, It will be not recorded because it is not considered a dangerous alarm.

10.6 ALARM REPORT When a new alarm event intervenes, the User can decide the type of print with the PRINT ENABLE parameter: if PRINT ENABLE = NO the alarm print is not enabled. if PRINT ENABLE = CON each alarm event correspond to an immediate print out of the event itself. if PRINT ENABLE = INT the print is delayed for the time set in TIME CONFIRM parameter. Therefore if e.g. TIME CONFIRM = 60 minutes, the local print out will be executed ONLY if there have been changes in the alarm conditions during the last hour. Remember that the print and the fax have the same report.

With PRINT ENABLE = CON it is possible that you fill find one report page for each alarm event. This can happen because some printers gives automatically the form feed command (eg laser and desk jet).

If the alarm print report can not be printed, after two minutes the printing queue will be erased after two minutes. In this case the message PRINTER ERROR will appear on the display.

10.7 ALARM FAX MESSAGE If the fax device is enabled under USER MENU - SETUP - ALARM - TX FAX ENABLE, the XJ500 will provide to send a warning message to the selected priority phone numbers (see the CALLING NUMBER list). The XJ unit sends the alarm report every interval time defined in “TIME CONFIRM”. Therefore if e.g. TIME CONFIRM = 60 minutes, the fax will be sent ONLY if there have been changes in the alarm conditions during the last hour. When it is necessary to send a fax message, the XJ500 unit selects the first phone number programmed in “CALLING NUMBER” . If the line is not free, the unit will attempt the connection for the NUMBER OF RETRY, the interval time is defined by TIME DELAY BETWEEN TWO CALLS. If no connection has been established, the unit selects the second number of and tries again.


1592010001 XJ500 v3_4 GB r1.1 16_04_2003.doc XJ500 Pag.35 / 47

If the alarm fax message can not be sent for any reason, the fax will be cancel after the last retry and the FAX ERROR message will appear on the display.

13 SPECIAL FUNCTION 13.1 TIMER 1 AND TIMER 2 The XJ500 unit is provided with two auxiliary relays which can be related to a daily or a weekly cycle. Two different timers are programmable in order to define the cycle executed by the relays. Possible applications for this function are the light and the blind controls.

HOW PROCEED 1) Define the ON/OFF cycle for Timer 1 and Timer 2 2) Select the relation between the relay outputs and the timers.

DEFINE THE TIMER FOR THE CYCLE TIMER 1 and TIMER 2 are daily cycles made of 144 On/Off operations with a step of 10 minutes. Each timer can be program independently and used during the week both for Aux 1 and Aux 2 relays. Example:


1592010001 XJ500 v3_4 GB r1.1 16_04_2003.doc XJ500 Pag.40 / 47

INTERVAL TIME RELAY STATUS from 8:00 to 12:30 on from 12:30 to 16:00 off from 16:00 to 20:00 on

Under SETUP-SYSTEM-SPECIAL FUNCTION-TIMER: with the o key select TIME = 08:00; push > and keep it pushed: the STATUS label changes from OFF to ON; by keeping the > pushed, push also < until the TIME reaches 12:20; release all keys; push o to set TIME = 12:30; select OFF with < and keep it pushed; by keeping < pushed, push also the o until the TIME = 16:00; release all the keys; push > and keep it pushed: the STATUS = ON; by keeping the > pushed, push also the o until TIME = 20:00; press ENTER to confirm the programming:

13.1.1 SET THE RELATION BETWEEN THE TIMER AND THE RELAY OUTPUT Under the parameters WORKING MODE, the User is allowed to define day by day the operations of the relay output:

WORKING MODE STATUS Selectable Function OFF the relay will not execute any operation. TIMER 1 the relay will execute the cycle set in Timer 1. TIMER 2 the relay will execute the cycle set in Timer 2. MANUAL the relay can be switched ON and OFF by mean of the AUX key button

Next example shows the procedure to define a weekly cycle executed by the auxiliary relay 1:

WORKING MODE Day Relay AUX 1 Sunday OFF Monday Timer 1 Tuesday Timer 1 Wednesday Timer 2 Thursday Timer 1 Friday Timer 1 Saturday MANUAL


1592010001 XJ500 v3_4 GB r1.1 16_04_2003.doc XJ500 Pag.41 / 47

Under SETUP - SYSTEM - SPECIAL FUNCTION - AUX1 WORKING MODE; select Sunday = OFF; push one time n for Monday then push > to select TIMER 1; push one time n for Tuesday then push > to select TIMER 1; push one time n for Wednesday then push > to select TIMER 2; push one time n for Thursday then push > to select TIMER 1; push one time n for Friday then push > to select TIMER 1; push one time n for Saturday then push > to select MANUAL; push ENTER to confirm the new data. The same method is used to set the AUX2 weekly cycle. Remember that Timer 1 and Timer 2 are independent and they can be used for both the relays.

13.1.2 SET THE MANUAL CONTROL FROM THE XJ500 KEYBOARD Suppose that every Saturday the AUX1 relay must be manually turned on and off by the user. To make this operation set under SETUP - SYSTEM - SPECIAL FUNCTION - AUX1 WORKING MODE = MANUAL (Saturday). When the instrument is not in programming mode, by pushing the AUX key the User can check which is the active function selected for the auxiliary relay. If no function is selected the DISABLE message will be showed:

< AUX STATUS > AUX1: OFF AUX2: MANUAL

If for that day the MANUAL option is selected, it is possible without entering the programming to manage the ON/OFF status: Select the AUX1 with o or n; Push < or > to change the status; Push ENTER to confirm. By repeating this operation you can switch manually the relay.

13.2 SYNCHRONISED DEFROST This function allows to set a synchronised defrost cycle both for one instrument and groups of instruments. The synchronised defrost is based on a daily timer which is programmable with a step of 10 minutes for a total of 144 possible defrosts, and moreover the User can select from 1 to 10 instruments for each defrost operation. The defrost timer follows the Real Time Clock of the XJ500 which send the defrost command to the selected instruments. Each instrument will carry out the defrost by following the local evaporator condition and the parameter programming. For example: if the evaporator temperature is too high the defrost will not be executed.

If the XJ500 loses the clock synchronism, each instrument will automatically restart working with its parameter programming defrost cycle.

13.2.1 THE PARAMETER OF THE DEVICE TIMER TIME sets the hour and the minutes of each defrost with a step of 10 minutes; FUNCTION enables the defrost function at the selected TIME; ADD adds to a list up to 10 devices to one defrost command; ERASE deletes the instruments from a list; VIEW allows to show the defrost setting.


1592010001 XJ500 v3_4 GB r1.1 16_04_2003.doc XJ500 Pag.42 / 47
