Table 7: Troubleshooting

Problem

Possible cause and correction Verification

Configurable output - analog

mode is invalid

:

0–10 V output is set to 10–

100%, but 0 V is at output

terminals.

Output is in protection mode

,

a state the analog portion of

the configurable output goes

into when it detects a wiring

problem. The analog output

is set to 0% regardless of the

command whenever a wiring

fault is detected.

Cause:

There is a power polarity

mismatch between the

connected device and the

configurable output.

Correction:

Ensure polarities of ~24 V COM/

OCOM match and that the

connected end device uses the

same polarity.

1. Measure the output and

verify that it matches the

command.

2. Disconnect the connected

device and verify the

commanded value is

present.

Configurable output - analog

mode is invalid

:

0–10V output has an

undesirable offset of up to 1 V.

The Common Reference is

incorrect.

Cause:

The OCOM terminal is not

connected.

Correction:

Connect the OCOM terminal of

the configurable output to the

common of the connected end

device.

1. Measure the output and

verify that it matches the

command.

2. Disconnect the connected

device and verify the

commanded value is

present.
