b)
Power Fail Operation Option Test
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 S3 to the same position as switch S2 (Figure 4).
2. Turn on gate operator power switch.
3. Using the manual controls (Figure 5), 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 S3 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 S3 to the direction you desire the gate to move after a power outage.
