1.9 Pan Stops (345° Models)
Locate the three (3) limit stops on the base of the unit. The
red limit stop is the Fixed Stop. It is not adjustable and
should not be removed. The remaining two (2) stops
are
called the Pan Stops. These are positioned on each side of
the pan switch lever.
The two (2) pan stops are adjustable and secured with a set
screw. The screws can be accessed through the hole in the
end of each stop. Use a 3/32-inch Allen wrench (supplied) to
loosen and tighten the set screw. See Figure 3: Pan Stop
Locations (345° Models).

2 OPERATION
2.1 Manual Pan Operation (345° Models)
The pan stops establish the limits for manual pan. The two
(2) adjustable pan stops may be repositioned or removed
depending on the desired operation. The maximum pan
range setup is shown in Figure 4: Maximum Manual Pan
and Maximum Auto-Pan (345º Models).
Caution: Never move or remove the fixed
stop. It must always be in place for proper
operation of the pan function.
2.2 Auto-Pan Operation (345º Models)
Use of the auto-pan function requires wiring connections to
pin 16 (Pan Left), pin 18 (Pan Right), and pin 19 (Common).
See Figure 6: Wiring Diagram (0º - 345º Models). The
auto-pan function is achieved by the controller unit sensing
changes in current flow through the pan motor. When a pan
stop is reached, the current flow stops and internal circuitry
of the controller unit reverses the auto-pan direction.
Note: The pan/tilt controller must be equipped with special
current sensing circuitry to operate the auto-pan function in
this mode.
The pan stops or the fixed stop establish the limits for auto-
pan.

2.3 Pan Stop Adjustment (345° Models)
1. Loosen the pan stops and adjust to the desired range for
manual pan and auto-pan. A recessed area in the pan
head allows enough clearance to remove a stop from
the base.
2. When all the stops are in place, check to see that they
are secure.
3. Operate the unit from the controller to confirm that
the limits are set properly. Readjust if required.
2.4 Pan Operation (360° Models)
These models allow 360 degree rotational (pan) operation.
They have no pan stops. These units can be manually panned
left or right or they can be panned continuously left or right
by auto-pan activation. Auto-Pan activation requires wiring
connections to pin 16 (Pan Left), pin 18 (Pan Right), and pin
19 (Common). See Figure 7: Wiring Diagram (360°
Models).
