Operator Setup (cont.)

Limit Nuts Rough Adjustment (Cont.)

After fi nishing the initial limit cam adjustments, reposition
the gate to approximately the center of travel. At this time,
adjust the torque limiter as explained below. Turn the power
disconnect switch ON, stand clear of any moving parts
and press the OPEN button. Observe the gate as it runs
through a complete cycle in both directions, and adjust the
limits again if necessary. If the operator stops during travel,
you may need to adjust the open or close current sensor
adjustment or the maximum run timer (see Page 13).

Torque Limiter Adjustment

NOTE: The open and close current sensing may need to be

adjusted before performing the following two steps. See Page 13.

Before adjusting the torque limiter, make sure the gate
is in good working condition. With the gate disconnected
from the gate arm, one person should be able to move the
gate by hand. Be certain the gate moves freely and without
binding throughout its travel.

Torque limiters are set light at the factory. They must be
adjusted during installation, preferably after limit cams have
been manually set. With the gate arm and gate attached,
adjust the torque limiter tight enough to keep it from slipping
during normal operation. The inherent entrapment protection
(current sensing) feature must activate prior to any slipping
of the torque limiter. See Page 13 for current sense setting.

To adjust the torque limiter in model SWG:

1. Bend the locking tabs away from the adjustment nut.

2. Cycle the gate open and closed while observing the torque limiter

action. TURN THE OPERATOR POWER DISCONNECT SWITCH
OFF BEFORE MAKING ANY ADJUSTMENTS
.

To increase the torque, turn the adjustment nut clockwise one fl at, or
1/6 turn, at a time until desired output is obtained.

To reduce the torque, turn the adjustment nut counterclockwise one
fl at, or 1/6 turn, at a time until desired output is obtained.

3. When fi nished, bend the locking tabs up to lock the adjustment nut

in place.

Limit Cam Fine Adjustment

After fi nishing the rough limit cam adjustments and torque
limiter adjustment, reposition the gate to approximately the
center of travel.

1. Turn the power disconnect switch ON.

2. Stand clear of any moving parts and press the OPEN button.

3. After the gate opens, press the CLOSE button.

4. Observe the gate in both directions as it runs through each complete

cycle. Adjust the open or close limit cams again if necessary. If the
gate stops during travel, you may need to adjust the Open or Close
Current Setting or the Maximum Run Timer (see Pages 13-14).

CAUTION

If the operator is installed in a left-hand installation. Set the
Controller to left-hand operation BEFORE running the operator
for the fi ne setting of the limit cams. Failure to do so will
result in over-shooting the limit switches, and may cause
damage to the operator and/or gate. Refer to programming on
Page 12.
