4.0 PAN/TILT LIMIT ADJUSTMENTS
CAUTION: DO NOT attempt to adjust limit
stops when the pan/tilt is in operation. Damage
to the equipment can result. Do not operate
equipment without limit stops.
To adjust limit stops, perform the following steps:
1. Pan to the right using the joystick control until the
desired pan limit is reached. Remove the drive unit
from the back box and adjust the pan limit stop
until it clicks the limit switch. Lock the limit stop
into position and replace pan/tilt. (See Figure 13.)
2. Pan left to the desired stop location and follow the
limit stop adjusting procedure outlined in step #1.
3. Pan left and right to verify that the limit stops have
been positioned properly.
4. The tilt table is designed to move -90° from the
horizontal plane. Note that the tilt adjustment must
never be adjusted beyond the 8 to -90° boundaries.
5. Loosen the limit stop actuator (shown in Figure
12). Use the joystick to move the tilt table to the
maximum tilt-up location and then move the limit
stop actuator until it clicks the tilt-up limit switch.
Then lock the limit stop actuator by tightening the
locking screw.
6. Tilt up and down to verify position of the tilt table.

Note:
• Factory pan limits are set to 0-355° and tilt limits
are set to 0-90° (horizontal to vertical).
• Under normal conditions, the tilt limits should not
have to be reset.
• SL models feature the 360° pan option and are not
supplied with pan limit stops, therefore, only the
tilt limits can be adjusted.
• Pan and tilt spindles are not corrosion protected
and will show signs of corrosion deposit. This is a
normal condition and will not affect the perfor-
mance of the unit.
