Run Alarm and Pre-start Alarm
The factory default is Run Alarm on and a 3-second Pre-start Alarm. The
operator’s beeper will sound 3 seconds before the operator starts. The
options are:
Run Alarm Off and Pre-start Alarm Off •
Run Alarm On and Pre-start Alarm Off •
Run Alarm On and Pre-start Alarm On for 3-9 Seconds •
Maximum Open Direction Current Setting
To detect obstacles or mechanical problems with the gate, the operator
monitors its motor current. If the open current load exceeds the
programmed maximum load range number, the operator will stop, reverse
a short distance, then stop again. The Auto Close Timer will be disabled,
and another open request will be required to start the operator again. If
after restart, the overload or an open obstacle happens again before the
open limit is reached, the operator will lockout and sound the alarm.
To measure the motor load used during opening,
while this function is
being displayed, push and hold the OPEN button to fully open the gate.
During movement, the motor current will be displayed as a load number
from 0 to 99. This number is useful for troubleshooting but not for setting
the motor current. At the end of travel, a different number will flash. This
number indicates the range above and below the average motor current
during the run. Using the + and - buttons, set the programmed range
number above the indicated range number, so that a minimal force (30-
40 lbs. at 10-feet) will activate a reversal should an obstruction occur, but
high enough to keep the gate moving under normal conditions without
interruption.
Maximum Close Direction Current Setting
To detect obstacles or mechanical problems with the gate, the operator
monitors its motor current. If the close current load exceeds the
programmed maximum load range number, the operator will stop, reverse
a short distance, then stop again. Another close request will be required
to start the operator again. If after restart, the overload or a close obstacle
happens again before the close limit is reached, the operator will lockout
and sound the alarm.
To measure the motor load used during closing,
while this function is
being displayed, push and hold the CLOSE button to close the gate.
During movement, the motor current will be displayed as a load number
from 0 to 99. This number is useful for troubleshooting but not used for
setting the motor current. At the end of travel, a different number will flash.
This number indicates the range above and below the average motor
current during the run. Using the + and - buttons, set the programmed
range number above the measured flashing range number, so that a
minimal force (50-75 lbs.) will activate a reversal should an obstruction
occur, but high enough to keep the gate moving under normal conditions
without interruption.
