LED Trouble
Indicator
Overview
The code produced by the lit indicator LEDs corresponds to a trouble that is either occurring on
the System or on the SLC Channels. See Table 7-4 for the LED definitions.
See Table 7-5 and Table 7-6 for the LEDs and their codes.

System Trouble
LED Codes
System troubles are indicated by LEDs A to E.
Table 7-5. System Trouble LED Codes
LED:
A, B, C, D, E
These 5 yellow LEDs are used to signal
various trouble conditions on the EPS and
its SLC. See the troubleshooting section for
LED system codes.

A B C D E Description:
No Trouble: There are no troubles detected on the system.
AC Fail: The AC power is disconnected but the battery is working.
Low Battery: The battery charge is under 22 V.
Battery Cutout: The Battery charge is below 20V. At this point if jumper
P16 is set to “battery disconnect when depleted” the system will shut
down.
Depleted/Missing Battery: If jumper P16 is not set to “battery
disconnect when depleted” this trouble will appear when the battery
charge is below 20 V. This code will also appear if the system cannot
detect the battery.
Charger Trouble: There is a trouble with the battery charger.
Card Overcurrent: The EPS module is drawing too much current.
Negative Earth: The circuit is shorted to ground on the negative wire.
Positive Earth: The circuit is shorted to ground on the positive wire.
Negative Earth on RUI+: The RUI circuit is shorted to ground on the
negative wire
Positive Earth on RUI+: The RUI circuit is shorted to ground on the
positive wire.
City Circuit 1 Trouble: The trouble configured on the City Card’s circuit
one has bee triggered.
City Circuit 2 Trouble: The trouble configured on the City Card’s circuit
two has bee triggered.
AuxNAC Open: Depending on the chosen configuration, either is the
Aux circuit or the NAC circuit is open.
AuxNAC Short: Depending on the chosen configuration, either is the
Aux circuit or the NAC circuit is experiencing a short circuit.
AuxNAC Overcurrent: Depending on the chosen configuration, either is
the Aux circuit or the NAC circuit drawing too much current.
