Rewire battery set.
Incorrect battery
hook-up.
Remove primary power and batteries, then
replace fuse. CAUTION.
Blown battery fuse.
4) No battery back-up
Verify switch settings in Section III.
Incorrect switch
setting.
Measure xfmr secondary voltage. If not within
proper range, replace transformer.
Incorrect or defective
xfmr.
Rewire battery set.
Incorrect battery
hook-up.
Remove system load and batteries; check
system output voltage. If OK recheck system
requirements, and/or measure output current
draw with an ammeter.
The system load is
greater than the
supply capability.
Check battery condition and replace if needed.
Defective battery.
3) Incorrect output voltage
Check xfmr secondary voltage at PC board
"Low Voltage AC Connection". If voltage is not
present, replace xfmr.
Loss of transformer
(xfmr) power.
Remove primary power and batteries, then
replace fuse. CAUTION.
Blown AC fuse.
Check AC primary supply.
Loss of AC power.
2) Green "AC" LED is not
illuminated.
See Symptom 4.
Blown battery fuse.
