J. POWER FAIL OPERATION OPTION CONNECTION
a) Power Fail Operation Option Connection
CAUTION
Perform the next step (battery hookup) with care. Interchanging battery wires temporarily opens
the the resettabale fuse on gate operator board, disabling the power fail option.
To ensure a safe installation, the gate operator is shipped with the battery partially disconnected
from the Power Fail Option electronics. To enable this option:
• Connect white/red wire of option harness to positive (+) battery terminal.
b) Power Fail Operation Option Test
NOTES:
• The following procedures require turning main power to the gate operator off and on at its
dedicated circuit breaker. DO NOT shut off the Gate Operator Power switch unless
specifically directed by the procedure, since this will shut off everything, including the
Power Fail Operation option.
• Because the battery may not be fully charged at the time of the test, we strongly suggest
moving the gate only one foot when performing the power fail test.
1. Set Power Fail switch S2 to the same position as switch S1 (Figure 12).
2. Turn on gate operator power switch.
3. Using the manual controls (Figure 13), initiate gate opening, then stop the gate about one
foot short of its fully open position.
4. Turn off main power to the gate operator. After about one minute the gate should start
opening and stop at its fully open limit.
5. Turn on main power to the gate operator.
6. Set Power Fail switch S2 to the opposite position.
7. Using the manual controls, initiate gate closing, then stop the gate about one foot short of its
fully closed position.
8. Turn off main power to the gate operator. After about one minute the gate should start
closing and stop at its fully closed limit.
9. Turn on main power to the gate operator.
10. Set Power Fail switch S2 to the direction you desire the gate to move after a power outage.
