Instrument Faults
When using your own power supply, make sure that the voltage is
regulated to 24 VDC ± 0.5 Volts. A voltage that is too low or too high
will activate a Supply Voltage Out of Range fault and disable
the OMS.
The OMS incorporates a number of self-checking features to ensure reliable
operation. If a fault condition is detected, the analog output signal is altered as
follows:
All system faults are displayed on the front panel. Each fault has a
unique code to identify the specific problem. Contact ETS-Lindgren if
a fault is displayed.
