6.10Troubleshooting

The code produced by the illuminated indicator LEDs corresponds to a trouble occurring on the system. See Table on page 36 for the IDNet LED
definitions, and see Table on page 36 for the 4007ES trouble messages.

Normally off. Turns on steady if the IDNet is
not communicating with the FACP CPU.
Normally off. Illuminates to indicate a problem
with the IDNet channel:
• Channel failure.
• Line short.
• Class A failure or an open line.
Illuminates to indicate a positive earth fault.
Illuminates to indicate a negative earth fault.
Steady ON: Indicates an open or short
condition on indicated loop.

Definition
AC power is not present or is too low for proper system operation.
The battery voltage is below the 22.8 V nominal level by 10% or more.
The battery is either below 19.4 V or completely undetected.
The module is drawing more current than it should. Check for faults on the circuit.
The battery charger is either defective or being heavily loaded by batteries. Read charger current at front panel,
if charger current is approximately 1.4 A, batteries are likely loading the charger. Remove battery connection and
measure the output. If the output is 27.6 (or close, temperature dependent), there is a possibility of depleted
batteries or a bad set of batteries. Allow batteries to charge or replace them if they do not take a charge.
If the current is ~1.4 A with batteries and charger voltage below 20 V, remove the batteries and recheck the charger
voltage. If the voltage is around ~27.3 V, then the batteries are heavily depleted.
Appears if one or more extra devices (i.e., devices that have not been configured for the IDNAC or IDNet channel) are
on the system. Only one message appears, regardless of the number of extra devices found.
Comes up during the Earth Fault Search diagnostic function. Once the search is initiated, the front panel display
indicates how far along the search process has progressed (10%, 25%...75%), and then shows the results of the
search. The result either identifies the offending circuit or indicates that the earth fault could not be found. During
the search of circuits (IDNet, NAC, IDNAC, and aux power), system alarm and trouble processing is suspended.
Appears when a positive earth fault is detected.
Appears when a negative earth fault is detected.
Appears when a short is detected on the IDNAC/NAC channel. This status clears automatically when the short circuit
is removed.
Appears when each device on the IDNet channel has been configured, and when none of the devices are
communicating on the channel. This message does not appear if there are no configured devices on the IDNAC
channel.
