Notes

1.NC -- No Connection, do not use.

2.(Color Codes) indicate feed-thru wiring to camera/housing.

3.Apply to 24 volt models only. Pins 10 thru 12 are not used in 110 volt or 220 volt models.

4.(Color Codes) shown are for 24 volt and 110 volt models. For 220 volt models, color codes are (23) Brown, and (24) Blue.

5.The conductors for pins 16 thru 24 (where applicable) on 220 volt models should be isolated from other wiring with reinforced insulation requirements of DIN VDE 0860/05.89, IEC 65. The conductors for pins 16 thru 24 (where applicable) must be

in HAR cord minimum cross sectional area 0.75 mm2 (H05 VV-F).

6.Refer to Figure 6 under Wiring Diagrams for the wiring schematic.

7.Refer to Figure 7 under Wiring Diagrams for the wiring schematic.

8.Pre-Position models only. Refer to Figure 8 for the wiring schematic.

3.8Pan 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.

4 OPERATION

4.1Manual 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.

Caution: Never move or remove the fixed stop. It must always be in place for proper operation of the pan function.

4.2Auto-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. 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.
