Problem Description
Recommended Actions
Open circuit detected on CH1
Check output wiring, ensure all
connections are present and secure,
there are no breaks in the wires, and
there is no exposed conductors that
can cause short circuits .
Ensure that the end measurement
device (DCS, DAQ, PLC, multimeter,
etc .) is correctly configured to read
the signal conditioner’s output signal
(current for 0-20/4-20 mA, voltage for
0-5/0-10 V
dc
) .
If a resistive load is being used for
measurement, ensure it is properly
valued .
Load should be 1k Ω minimum for
voltage configurations .
For current configurations, load must
be configured so that compliance
voltage (voltage powering the device)
is not exceeded (1k Ω maximum
recommended for a compliance
voltage of 24 V
dc
) .
Short circuit detected on CH1
Open circuit detected on CH2
Short circuit detected on CH2
CH1 overheat detected
The signal conditioner detected a
temperature outside of its operating
range while running . Ensure operating
environment/enclosure does not
exceed 80 °C .
CH2 overheat detected
Hardware configuration error
Power cycle the device .
Check wiring for correctness/
robustness; ensure signal conditioner
common is NOT tied to earth/chassis
ground .
Try re-programming .
Try setting to ISO .
Internal communication bus fault
