EXTERNAL OBSTRUCTION CIRCUIT
This circuit can be used with either a gate edge or a photo beam system. When either of the two
devices mentioned are activated, the operator will react in a similar manner to the inherent
obstruction described above.
NOTE: If external entrapment protection is required by the class of operator, both an open
and closed protection device must be used.
SPECIAL NOTE ABOUT OBSTRUCTION SENSING FROM EITHER INTERNAL OR
EXTERNAL SYSTEMS
The operator will stop if it senses two sequential obstructions. If will not activate form any
automatic system, including the built in time delay to close. Either a manual device such as a
pushbutton within site of the gate and operator, or the stop button supplied with the operator must
be activated to resume the operator back to its normal operation.
OPEN ONLY CIRCUIT
Separate open circuits for line-of sight devices and out-of-sight devices such as open loops or
radio controls.
LOOP CONTROL CIRCUITS
Vehicle control devices such as opening or security loop detectors are connected to this circuit
TIME DELAY TO REVERSE CIRCUIT
Allows the gate to come to a complete stop before reversing direction. Approximately ½ second
between stop and reverse.
NOTE: This feature is defeated when either the inherent or external obstruction circuits
are activated.
