11 "Tam" Position Feedback Transmitter - Bernard Controls SQX TOTAL N31272 Manuel De Mise En Service

Setting of potentiometer zero is achieved thanks to the «0% postion»
screw.
Drive the actuator to the closed position.
Resistance value is measured between terminals 16 and 17.
Hold the pinion located just under the plate with the «0% position»
marking while driving the potentiometer screw. Adjust the potentiometer
so that the resistance
value exceeds 0 Ohm and regularly increases then turn backwards to reach
a value as close to 0 Ohm as possible.
Drive the actuator to the open position and write down the resistance value corresponding to the
100% position.
Come back to the closed position and check that, for the 0% position, the resistance shows a close
to zero repeatable value.
Note: If actuator is equipped with 2 potentiometers, each potentiometer is set independently of
the other.
Signal inversion:
To inverse the signal variation direction, invert potentiometer wires on the actuator terminal board
(e.g. for a connection on 16/17/18, invert 16 and 18).
11 "TAM" POSITION FEEDBACK TRANSMITTER (OPTION)
The TAM transmitter delivers a 0/4 to 20 mA signal linearly proportional to the position of the valve.
Electric connections
Refer to the wiring diagram supplied with the actuator.See also some
typical wiring examples below.
Filtered or stabilised power supply should be provided within the 12 to
32 VDC range.
Maximum admissible ohmic load values are given in the table :
