Potentiometer
If there is no output signal, check electrical connec-
tions and for open circuit, check that potentio-
meter is not out of it´s mechanical range.
If output deflection is wrong reverse connection
terminals 7 and 9.
4-20 mA position transmitter
If there is no output signal, check electrical
connections, polarity, loop power supply, and
that the potentiometer is within its range.
If full output signal cannot be achieved by
adjustment, check supply voltage and jumper X
settings.
If output signal increases and decreases in the
wrong direction, move connector from A to B or
vice versa.
If the 4 mA fine adjustment P2 does not have
enough span, zero must be mechanically reali-
gned as follows: Turn P2 20 revolutions counter
clockwise, then repeat the transmitter calibration
procedure.
