The circuitry for the IGDPS is encapsulated in epoxy. As a result the
module can not be field repaired and there are no test points or
adjustments available on this board. If one of the six isolated 20 V
output fails, the entire board must be replaced.


Board LEDs

One operational green LED on each of the 6 outputs, visible from the
input ends of the unit that detects failed 20V output.


• LED ON: output healthy

• LED OFF: output voltage is below 18Vdc


If the HV IGDPS is healthy, then all six LEDs will be illuminated. If
this is not true, this may indicate either a bad connection to the board
or a defective output module.


Record the following measurements to ensure all 6 outputs are
functioning. They should be within ±1% of 20 V.

There may be more than one IGDPS. Record voltages for all of them.


If a channel has failed, refer to the troubleshooting section of the
manual for a replacement procedure.
