Caution ! Please follow carefully the combinations beside with the DIP switch. If the combination is wrongly done, the following message will appear on the display of the transmitter “CONF ERROR”. In that case, you will have to unplug the transmitter, replace the DIP switches correctly, and then power the transmitter up. To configure the transmitter, it must not be energized. Then, you can make the settings required, thanks to the DIP switches (as shown on the drawing beside). When the transmitter is configured, you can power it up.

To modify the configuration, please proceed as follows : Remove the 2 screws from the housing and open it. The settings are done with the button located on the electronic board (see photo beside). Principle : - By pressing on this button for more than 3 seconds, you can validate the setting and go to the next setting. - By pressing quickly on this button, you can increment a value and scroll down the different options or values. This button enables : 1- to activate/deactivate an alarm (set point) 2- to program the action of the alarm (rising/falling/regulation action) 3- to set the set point value 4- to set the time-delay (temporisation) • Setting of units To set the measuring unit, please set the on-off switches 2, 3 and 4 of the units, as shown beside. mmH2O inWG mmHG PSI Configurations Pa mbar KPa 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 Combinations PST-1 and PST-2 X X X X X PST-3 and PST-4 X X X X X To set the different options : 1- Activating/deactivating the alarm : After pressing the set point configuration button for more than 3 seconds, will be displayed, then or (depending on the last configuration of the transmitter). Afterwards, by briefly pressing on this button, you can switch between (alarm on) and (alarm off). To validate your choice, press again for 3 seconds. If you chose , then you will exit the configuration mode and switch back to the measurement mode. If you chose , you will move to the next parameter. 2- Programming the action of the alarm (rising/falling/regulation action) : Rising action (1 set point) : the alarm will activate when the measure exceeds the set point and will stop when the measure goes below the set point. Falling action (1 set point) : the alarm will activate when the measure goes below the set point and will stop when the measure goes above the set point. Regulation mode (2 set points) : the set point values will determine the action type. Two possibilities are available: Press the button for 3 seconds to confirm your choice. You will then move on to the last parameter. 3- Programming the set point value : The set point is a limit which, when being reached and/or exceeded, activates the relay and the visual red LED alarm. The first digit will start to blink, by briefly pressing on the button, you can choose if the set point will be either positive (0) or negative (-). Then press the button during 3 seconds to confirm your choice. The second digit will start to blink. Press the button briefly to change the value. Then press the button during 3 seconds to confirm your choice. Repeat this sequence until you have reached the last digit and then confirm the set point. If you selected regulation mode , you will program the second set point. 4- Setting of the time-delay (dead band temporisation 60 sec max) : When the set point is reached and/or exceeded, the time-delay will wait the specified time before energizing the relay, if the set point is still reached and/or exceeded. When the first digit starts blinking, press briefly on the button to change the value. Then press the button during 3 seconds to confirm your choice. Repeat the process until all digits have the desired value and press the button for 3 seconds to confirm your choice. The programming is now done and the display switches back to the measurement mode.

Caution ! Once the transmitter is installed and energized, please proceed to an autozero to guarantee the correct working of the transmitter, whatever the position of the transmitter is. An easy and friendly way to configure! You can configure the measuring units, the set point, the time-delay.... Installation : mount the ABS plate on the wall (this plate is supplied with the transmitter). Drilling : Ø 6 mm, with the screws and pins supplied with the transmitter. Insert the transmitter into the plate (see points A of the drawing beside), by tilting it at 30°. Rotate the housing in clockwise direction until you hear a “click” which confirms that the transmitter is correctly installed. Please avoid any aggressive solvent. Please protect the transmitter and its probes from any cleaning product containing formol, that may be used for cleaning rooms or ducts. ! Caution ! The configuration can be made either by switch, or by software (you can not combine both solutions) Initialization of the transmitter 4- The set point (alarm on) This message is displayed : ex : , which means that the alarm will be activated as soon as the measurement exceeds this value. 5 - The time-delay (alarm on) This message is displayed : . The temporisation is in seconds (from 0 to 60 sec.). , After having displayed the configuration, the transmitter displays which confirms that the nitialization is finished and you can start the measurements. 250 . . i.sec . .
