General diagnosis
Trouble conditions are diagnosed by viewing the detailed information in the event
log, using an LCD keypad.
To view the event log:

Trouble conditions
Look for the specific problem you are experiencing and follow the instructions to
correct the problem.
The control panel shows a service condition after exiting programming.
This condition is normal immediately after exiting programming because the
panel scans the keypad bus for 12 seconds after the exit, while it looks for, and
enrolls, any new devices.
After exiting programming, wait 12 seconds before executing any commands.
Keypad text is showing on one LCD keypad, but not on the other keypads.
Make sure all keypads are addressed using the *, 9, 4 commands.
Enter and exit programming to enroll the new device numbers.
From the keypad with text, enter the following key sequence:
*, 9, 2, installer code, 1, #, #, Exit.
After approximately 30 seconds, the text transfers to all keypads.
The control panel has an overcurrent service condition.
1.
The control panel’s auxiliary power is overused. To correct this condition, add
up the current used by all devices powered by auxiliary and keypad power.
The total should be under 1 A with a 40 VA or 50 VA transformer, or under
500 mA if you are using a 25 VA transformer. If that value is exceeded, power
some devices from an NX-320E (or other auxiliary power supply).
2. A device powered by the keypad bus or auxiliary power may be shorted. To
correct this condition, remove all powered devices except one keypad. If the
trouble condition disappears, reconnect the devices back one at a time until
the condition reappears, then locate the sh
ort on that device’s wiring.
