TAM position transmitter (OPTION)
The TAM transmitter delivers a 4 to 20 mA signal linearly proportional
to the angular position of the valve.
Electrical connections
To connect TAM, refer to the wiring diagram supplied.
Filtered or stabilized power supply should be provided within the 12
to 32 VDC range. Maximum admissible resistance values are given
in the following table:

Signal direction inversion
The TAM transmitter, when supplied with a clockwise closing
actuator, provides a signal that rise from close position to open
position.
If an opposite signal variation is required, simply move 2 jumpers on
the board near the potentiometer:
•
direct signal: jumpers on 1-3 and 2-4
•
reversed signal: jumpers on 1-2 and 3-4
