DC Output Fuse
Bad
1) Open the charger access panel and verify DC voltage is above 6 volts
at the DC A.A.R. terminals. The UIM module needs a minimum of 6
volts to power on.
2) If voltage is above 6 volts, verify the DC fuse on A.A.R. terminal board
is not open. If fuse is still good, then see next possible cause.
3) If DC fuse is bad, then replace it with the same type and rating after
doing a visual check of charger unit.
No DC Voltage
at the UIM
1) The UIM gets DC voltage through the 5 wire cable from the back
plane connected on the left side of the UIM board assembly.
2) For safety, disconnect both the AC input and DC battery voltage from
the chassis.
3) For a four module shelf, remove the screws on the top of the UIM
cover and tilt the UIM out to access this connector. On a two module
case, the back cover over the UIM will need to be removed to access
the connector.
4) Continuity can be measured at this connection before replacing the
UIM module. The red wire on the cable should have continuity with
the DC plus at the A.A.R. terminals and the black wire on the cable
should have continuity with the DC minus at the A.A.R. terminals. If
necessary, the DC voltage can be measured here if very cautious.
5) If connections are bad, then the chassis will need replaced. If
connections are good, then see next possible cause.
UIM Module is
Bad
1) After the steps above are verified and the unit is still not functioning,
then replace the UIM module. Follow replacement part instructions to
remove and replace with a new UIM module.
No iPM
LED’s are ON
in Charger
Chassis Unit
No AC Input
Power to iPM
1) Is the UIM blue AC present LED on? If the blue LED is on, then the
AC input fuses are good and you have AC Input to the charger shelf
unit via the 2 wire connector to the UIM board. If UIM blue AC Present
LED is off, then see that symptom section.
2) iPM modules do not require a working UIM module so if all iPM
modules LEDs are off then continue to next possible cause.
Manual Control /
Output Control
Turned OFF
1) Using the Web server interface, check to make sure the charger
output has not been turned off by using the interface control. Check
the Current State Box on the dashboard.
2) Turn the charger output back on using the dashboard control if it was
off.
