7000A-RM001A-EN-P – January 2011 7000 “A” Frame
The circuitry for the IGDPS is encapsulated in epoxy. As a result the
module cannot 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.
IGDPS Board LEDs
There is one green LED on each of the 6 output channels of IGDPS.
If the IGDPS is healthy, then all six LEDs will be illuminated. If any
of the LEDs in not ON then the IGDPS might be defective and must
be replaced. Record the following measurements to ensure all 6
outputs in each IGDPS are functioning. The output voltage should be
within 20V + 1%. There may be more than one IGDPS in the drive.
