3.3 Automatic Limit Adjustment
This gate operator does not use any limit switches or run timers to adjust the gate open and close
positions. The gate open and close positions are determined by the physical stops on the crank arm.
The gate operator will automatically measure the travel distance required and set its "limits" from this
measurement during this initial automatic sequence.
!! IMPORTANT !!
This automatic limit adjustment sequence must be run prior to testing the operator for normal
operation, and prior to testing any of the safety features that are incorporated into this
operator. This includes the primary and secondary entrapment protection features, and the
entrapment alarm and reset features.
1. The limit adjustment is automatic and relies on the physical stop created by the flange on
the gate arm connector assembly.
2. Turn power to the operator ON. Activate an open device (or momentarily jumper
between terminals 11 and 20). The gate operator should begin to cycle the gate to the
OPEN position. If the gate operator begins to cycle the gate to the CLOSED position,
turn power to the operator OFF. Change the setting of the direction switch(s).
Primary or single operator, change SW 2, switch 1.
Secondary operator, change SW 2, switch 2.
3. After the initial activation with the gate running in the OPEN cycle, the clutch will slip for
approximately 2 seconds after the gate reaches the full open position, and then the gate
operator will shut off. Activate a keying device to close the gate (or allow the timer to
close the gate if it is turned on). When the gate reaches the full closed position, the
clutch will slip for approximately 2 seconds, and then the gate operator will shut off. The
operator limits are now set. NOTE: During this initial setup, be sure that the operator
clutch does not slip while the gate is cycling from the full open to the full closed position.
If the clutch slips during this period, the limits will be misadjusted.
4. Cycle the gate again. The operator should reach the full open and full close positions
and then shut off without the clutch slipping.
