Electrical Troubleshooting Guide
Analog Input
If the Analog Input is not functioning properly, verify the following:

Measure the input voltage. It should be in the correct range based on
configuration and wiring [e.g., (0 to 5) V (dc), (4 to 20) mA, or (0 to 200) mA.

Verify that Jumpers JPR3 and JPR5 are in the correct positions, note that
they both need to be set the same.

Check the values seen by the P-Series FL driver using the Service Tool and
verify that it matches the input signal.

Verify that there are no or minimal ac components to the Analog Input
signal. AC components can be caused by improper shielding.

Check the wiring. If the inputs are reading 0 or the engineering units that
correspond to 0 V, look for loose connections and disconnected /
misconnected cables/connections.

Check the software configuration to ensure that the input is configured
properly as the Demand Source.
PWM Input
If the PWM input is not functioning properly, verify the following:

Measure the input voltage, frequency, and duty cycle.

Check the values seen by the ProAct P-Series FL actuator using the Service
Tool and verify that is matches the input signal.

Check the wiring. Look for loose connections and disconnected /
misconnected cables/connections.

Check the software configuration to ensure that the input is configured
properly as the demand source.
CAN Input
If the CAN connection is not functioning properly, verify the following:

Check faults indicated on Service Tool.

Check the values seen by the ProAct P-Series FL actuator, if any, using the
Service Tool and verify that it matches the sent signal and/or received
signal.

Check the wiring. Look for loose connections and disconnected /
misconnected cables/connections. Verify 120 Ohm resistor at ends of
transmission lines.

Check the software configuration to ensure that the signal is configured
properly (Device ID, fail timeout, etc).

Check active device number. This is based on the CAN ID Hi and Low
inputs and their configurations.
Run Enable Discrete Input
If the run enable discrete input is not functioning properly, verify the following:

Measure the input voltage at the connector.

Check the status of the input from the Overview screen of the Service Tool.

Check the wiring, looking for loose connections or misconnected cables.

Verify the input is properly configured.
