6.5 Initial commissioning/start-up

6.5.1 Relay version

The relay version can only be used and set with the UNI display.

After connection of the pressure and temperature sensor to the voltage supply or aftervoltage return, the relays are set to the respective states.

6.5.2 Current version

The current version can be manually operated and set via the potentiometers and/or withthe UNI display.

When setting without the UNI display, the desired output current can be adjustedbetween 0 and 20 mA using trimmer potentiometers, once the respective pressure(min./max.) has been reached.

Also refer to: Connection diagram, current version chapter 5.6.6, page 29

After connection of the pressure and temperature sensor to the voltage supply or aftervoltage return, the respective current is output.

6.5.3 UNI display

The UNI display is used for indicating the measured values, setting, operation/controland diagnosis. The control unit is equipped with a battery, as well as a memory card forrecording the measured data.

! When changing the battery or SD card, ensure that it is correctly inserted !

6.5.4 Operation

The unit is operated using the four buttons on the UNI display.The individual menu items are indicated on the LCD.

The module automatically returns to the measured value display approx. 2 minutes afterthe last key is pressed. Any values that have not yet been confirmed with [OK] are lost.

We recommend working through the following chapters and setting the necessaryparameters to protect your system/plant.

Also observe the factory default settings!

Initial commissioning/start-up

1. Unscrew the housing cover.

2. Place the UNI display onto the electronics and press down gently.

The unit is now ready for operation.

7. Explanation of the menu items

7.1 Basic settings

The following settings are carried out in this menu item:

7.1.1 Languages [111]

Mark the desired language from the list of languages using the arrow keys [] or []and confirm the selection with [OK].

7.1.2 Lighting [112]

• Lighting »automatic«

In the position "automatic", the lighting is switched on when the pressure value (shownas a percentage) changes by 5%.

The display is also switched on for 15 seconds if the temperature changes by 5°C / 41°F.

The display is also switched on for 15 seconds whenever a button is pressed.

• Lighting "via button"

In the position "via button", the display is switched on for at least 15 seconds whenevera button is pressed.

Lighting "ON" - "OFF"

The positions "ON" and "OFF" switch the lighting permanently to the respective state

Note: If the display is unlit, the first button press switches the display on; this first buttonpress does not change anything in the menu.

7.1.3 Integration time [113]

The integration time calculates a mean value of the pressure over the set time period. Ifshort pressure fluctuations are permitted in the system, increasing this time offers thepossibility to work with more closely spaced switching thresholds

7.1.4 Basic calibration [114]

The menu item "Basic calibration" offers the possibility to set the display to zero at aparticular pressure. This can be the ambient pressure or an existing system pressure thatis not to be displayed as an offset.

The "min. calibration" and "max. calibration" specifies the pressure range throughoutwhich the display is to be scaled from 0 - 100%.

7.1.5 Sensor [115]

The selection of the sensor is pre-set by the manufacturer and does not need to bechanged.

If a different sensor is set (not the fitted sensor), the displayed pressure values will notbe correct.

Please refer to the name plate to see which type of sensor has been fitted.

7.1.6 Output [116]

The PTM can be supplied in two versions, one with two current outputs 0/4...20 mA forpressure and temperature, or one with relay outputs.

This menu item is pre-set by the manufacturer and may not be changed.

Please refer to the name plate to see which type of printed circuit board has been fitted.

7.1.7 Clock [117]

Clock and date setting:

for example 02.07.2012 09:12

The position to be changed is marked by "^^".

The next position to be changed is marked when [OK] is pressed. The order of setting isDay -> Month -> Year -> Hour -> Minute


Document 320354 – 2014/01/23 53

-> save and return to the submenu.

Each value can be changed with [] and [].

7.2 Output, relay PCB (PTM R)

7.2.1 Switching type, pump monitoring

The switching type "Pump monitoring" combines all the necessary safety functions formonitoring a pump for dry running and excessive temperature on one relay. Pumpmonitoring is the standard menu for simple setting with minimum external wiring work.

The following parameters apply to this switching type.

7.2.1.1 Permissible pressure

Switching type "Pump monitoring" (from PTM version 2.10, UNI display version 2.01):

Setting of the desired or permissible pressure range of the pump.

7.2.1.2 Permissible temperature


Setting of the desired or permissible medium temperature.

7.2.1.3 Pump starting time


The starting time of the pump can be set here, the set values are not monitored duringthis time. Set the starting time as short as possible to avoid damage to the pump.

The starting time should be selected such that the set minimum pressure is reached afterthe Start button (IN 1) is pressed.

Tip: If the pump is not switched off as a result of brief pressure fluctuations outside the set permissible pressure range e.g. due to air bubbles, it may make sense to increase the integration time (menu 113). The pressure is then averaged over a longer time pe-riod.

7.2.2 Pressure switching type / temperature switching type

The relay is exclusively assigned to the pressure or temperature of the medium.

The minimum and maximum switching threshold is set, and the timing, the switch-ondelay and the switching logic are adapted to the operating conditions with the additionalparameters in this menu.

The following parameters apply to this switching type.

7.2.2.1 Defining switching points (switching point 1 / switching point 2)

This is where the pressure or temperature values are set at which the relays are toswitch.

Note that the set value in "Switching point 1" must always be higher than the value in"Switching point 2". If the desired value cannot be reached, it is necessary to move thethreshold of the other switching point up or down.

7.2.2.2 Switching delays (switching delay 1/ switching delay 2)

for switching point 1 or switching point 2

The relay only switches when the switching point is reached and a set delay time haselapsed.

Note: If the "Window" operating mode is selected, it makes sense to set a sufficientlylong switching delay so that the switching points of the relay do not go back and forth.

The switch delay time allows the relay to only change its status when the time of the laststatus change has elapsed.


Document 320354 – 2014/01/23 54

7.2.2.3 NC / NO

The relays can either be operated as NC (normally closed) or as NO (normally open)contacts.

NOTE

Warning of damage to assets.

When selecting NC or NO, take into consideration that the relay is always in the statusNO during the initialisation of the PTM (1.5 seconds).

7.2.2.4 Operating mode

Hysteresis or window mode can be selected depending on the application.

• "Hysteresis" operating mode

Example: Fan control

Switching point 1 is set: 30°C, switching point 2: 20°C:

The fan switches on when the temperature increases to 30°C, the fan does not switchoff until the temperature decreases to 20°C.

Also refer to the diagram Hysteresis ope
