Fail Safe/Fail Secure Operation
Hold Open Timer
Connection Location
The Hold Open Timer function holds the gate at
the open position for a predetermined amount
of time, prior to closing automatically.
Set the Timer to the desired time, from 1 to
60 seconds.
If this feature is not needed, turn the Trim
Pot clockwise to the “off” position.
Note: The Hold Open Timer affects the “radio
receiver command” and the sequence of
operation for the gate (see page 24).
