BATTERY CHECKOUT
When the batteries become weak the gate will begin to run
noticeably slower.
(
NOTE:
Batteries should only be checked when
you are sure they have had adequate time to fully charge.)
Turn
off the ac power and run gate for 5 to 10 cycles while observing
low battery indicator LED D12. If LED 12 comes ON, batteries are
too weak to function properly. If LED 12 does not light, then
voltage should be checked as they still maybe near failure.
Correct voltage is approximately 25.5 Vdc.
(
NOTE:
If LED D12
does light, gate will open to conserve batteries in this test or in a
real power loss, even if mode switch 8 on S2 is off.)
Return of ac
power will clear low battery indicator. Correct charge voltage is
27.5 Vdc with batteries not connected (Set with R63, shown on
the Control Board Layout page).
