1. Check TB2 for proper connections.
2. Remove all field wiring and install dummy ELR at
output circuit. Check for supervisory voltage across it,
(Normal -2.3 V), if problem persists, replace circuit
board.
3. Removed dummy ELR, reconnect field wiring and
measure voltage across output; (trouble-5V, short 0V).
4. Check for ELR at last device.
5. Check field wiring.
1. Check TB4 for proper connections.
2. Remove field wiring for zone in trouble and install
dummy ELR (4.7K). If problem persists, replace
circuit board.
3. Check for ELR at last device.
4. Check field wiring.
1. Check installation manual.
Missing or 1. Check battery connections.
Disconnected
1. Remove batteries, check voltage across charger
output (17 to 19V), otherwise replace circuit board.
Low or
2. Reconnect batteries, measure battery voltage at
damaged
battery terminals. If voltage is less than 85% of rated
battery
voltage, allow them to charge for 48 hours.
3. If problem persists, replace batteries.
1. Remove field wiring from main panel and optional
module(s) (if installed). Install dummy ELR (4.7K).
2. Remove both battery leads.
3. If trouble clears, connect one circuit at the time to
pin point the problem.
4. If trouble doesn't clear, replace circuit board.
1. Move Municipal Box disconnect switch SW1 up.
1. Install optional module(s) or replace jumper if
module(s) is not used.
1. Install dummy load if Municipal Box option isn't
used.
2. Check Municipal Box wiring.
1. Remove field wiring and install ELR. If trouble
clears, look for faulty or incorrectly wired devices.
1. Cut associated jumper OPT1 or OPT2.
1. Make sure module is properly installed.
2. Move disable switch SW1 on 4XZM to the left.
1. Make sure that 4XLM module is installed on J8.
2. Check field wiring.
1. Replace circuit board.
1. Press system reset.
1. Check incoming power (TB5).
1. Replace circuit board.
1. Replace circuit board.
