Troubleshooting

Description of fault

Measures

Actuator moves too slowly.

Check the supply pressure.

Check the cross-section of the piping and

screw fittings.

Check the configuration of the mounting parts.

Actuator moves in the wrong direction.

Check piping.

Check the configuration of the mounting parts.

Air leaks from the positioner.

Check the seals in the connecting plate.

The set point span is not reached at a 100 % sig

nal.

Check whether the correct range spring has

been selected.

Check the adjusted air output and proportional

band.

Check the adjusted span.

Zero is not reached at a 0 % signal.

Check the adjusted zero.

Limit switch does not work properly

Check the limit switch setting.

Check the wiring and polarity of signal wires.

The solenoid valve frequently switches.

Check the supply voltage.

The position transmitter does not work.

Check zero and span at the position transmit

ter.

Check the wiring.
