Configuration
To configure the transmitter, please unscrew the 2 screws from the housing,
and then open it.
!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.

Power the transmitter up : it will then display its current configuration.
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.

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.

When the transmitter is powered up, it initializes and displays the digits and then its configuration including :
,
- 1 - the measuring range - 3 - action of the alarm (rising, falling or regulation action)
- 2 - the status of the alarm - 4 - the set point
- 5 - time-delay (dead band temporisation)
1- The measuring range
The following message is displayed : . This is the low value of the measuring range, and its digit value : ex : .
The following message is displayed : . This is the high value of the measuring range and its digit value : ex : .
The arrow displayed (at the bottom or on the right of the screen) is relative to the unit of measurement : ex : from -500 to 1000 Pa.
2 - The status of the alarm
When the alarm is off, the following message is displayed : .
When the alarm is on, the following message is displayed : .
• When the alarm is off, the transmitter displays which confirms
,
the end of initialization and that you can start the measurements .
• When the alarm is on, the transmitter displays the parameters relative to
the relay (set point, program of the alarm, time-delay).
3 - Action of the alarm (rising or falling action)
.
If the relay is programmed in rising action, the following message is displayed :
If the relay is programmed in falling action, the following message is displayed :
This message is displayed : ex : , which means that the alarm

!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.
