Pre-Position Model Connections
The following connection instructions are for models with
Preset capability. This includes the following models:
AD1240/24P - Preset model
AD1240/24PA - Preset with AutoPan
AD1240/24PH - Preset with Heater
The connector for Pan/Tilt and pre-position (Preset) control is
a 13-pin connector located on the rear panel of the AD1240.
On the AutoPan and Heater models, this connector also
supplies the appropriate voltage (24VAC) for these functions.
A mating connector assembly is supplied for connections.
The pre-position feedback is achieved by high-grade servo
potentiometers within the AD1240. These potentiometers are
used to feedback positional information from the AD1240 to
the external control system (e.g., Receiver/Driver).
• Check the polarity of the reference voltage connected to the
AD1240 to insure that movement of the unit causes the
feedback voltage to operate in the correct polarity for the
control system, i.e., panning right increases the pan wiper
voltage, tilt up increases the tilt wiper voltage.
Note: If the polarity is not correct, the unit will not
find its correct PRESET position.
• If a correction is necessary, reverse the polarity of the
reference supply connections.
Refer to the following table and Figure 8 for the AD1240
preset model pin definitions.
Shielded cable is recommended for most applications with the
AD1240 preset models.

Cable Strain Relief
The AD1240 Pan/Tilt is provided with a cable strain relief to
secure the power and signal connection cable to the main body.
This prevents accidental damage and chafing of the cable
during panning operation.
The connecting cable must be attached to the strain relief
assembly at the bottom of the AD1240 main body. Two tie-
down anchors are provided for attaching the cable to the main
body. The strain relief assembly is shown in Figure 10, below,
and its locations on the bottom of the main body are illustrated
in Figures 11 and 12 on page 11.
The AD1240 is delivered with the anchors attached to the
channel in the bottom of the main body, as illustrated in Figure
10, below. Two tie-wraps are provided separately, in the
package of mounting hardware supplied with the AD1240.
Note: If the tie-wrap anchors are not attached to the main
body at delivery, or are removed for any reason, attach
both to the main body bottom channel, as shown in
Figure 10, before mounting the AD1240 to a mounting
bracket.
To attach the connection cable to the strain relief assembly:
1. After wiring and assembly of the appropriate connector,
pages 7 - 9, connect the finished connector assembly to the
rear panel connector of the AD1240.
2. Feed each tie-wrap through the two anchors on the bottom
of the main body. (See Figure 10.)
3. Place the cable snug against the two anchors on the bottom
of the main body. (See Figure 12.)
4. Connect the tie-wraps around the cable, leaving enough
slack to adjust the cable.
5. Connect the cable inputs to an appropriate power source
and verify proper panning operation, in the full range
desired.
Adjust the cable position in the tie-wraps as necessary to
prevent binding.
6. Disconnect power and secure the tie-wraps on the cable.

SETUP
The AD1240 has two adjustable end stop switches which limit
the angle of travel for both the pan axis and the tilt axis. Set
these end stop switches to suit the site conditions. For models
with AutoPan, these end stops determine the end points of the
automatic panning action.
End Stop Limit Adjustment
SWITCH LOCATION
The limit switches for both Pan and Tilt movement are
located inside the AD1240 main body. To access the limit
switches, remove the four bolts on the front cover of the unit
(opposite the external connector) using the supplied 3 mm
Allen wrench, and remove the cover.
• The limit switches are located on the top plate of the pan
axis and tilt axis gearboxes (see Figures 13 and 14).
• The adjustable limit strikers are located on the end of
each axis main shaft (see Figure 14).
AXIS ALIGNMENT (Preset models only)
Before setting the limit strikers in the Preset models, the unit
must be aligned for proper travel of the preset potentiometer.
This alignment is important to prevent operation of the
AD1240 past the designed limits of travel.
Alignment marks (red dots) are provided on each axis main
gear and gearbox (see Figures 13 and 14, page 13) to assist
in aligning the unit. The AD1240, as shipped from the
factory, is set at the proper alignment positions for setting
the limit strikers. It is recommended that you confirm correct
lateral and vertical alignment of the actuator. Alignment by
the user is necessary only if the end stops are to be changed
after operation of the unit.
Align each axis by aligning the red mark on each main gear
with the red mark on the associated gearbox. (refer to
Figures 13 and 14 on page 13). Perform this alignment only
by applying control voltages (24VAC, ±10%) to the
applicable connector pins (Pan Left or Right, and Tilt Up or
Down).
Note: DO NOT attempt to rotate or position either axis by
hand, as this will cause irreversible damage to the
gears and transmission parts.
STRIKER ADJUSTMENT
Set the limit striker arms for the desired angle of travel to
suit the application. For Preset models, perform the Axis
Alignment (preceding paragraph) prior to this adjustment.
1. Push the appropriate adjustment arm in the desired
angular position for limit control of the Right/Left (Pan
axis), and/or the Up/Down (Tilt axis) direction.
• Adjust the limit strikers with finger pressure only.
The following are typical pan or tilt angle limit settings.
• The maximum Tilt setting is ±90°, or 180° limits.
Note: For Preset models, be careful not to push either
striker arm past the red axis alignment marks (see
Figures 13 and 14). The two striker arms must be
positioned on either side of the mark - do not
locate both arms on one side of the mark as
illustrated below.
2. Verify proper operation of the unit at both end stops
before re-attaching the front cover to the AD1240.
Note: Be careful when verifying operation of the unit -
any movement of the unit while the cover is
removed may cause damage to the unit.
3. Refit the front cover onto the AD1240 and tighten the
four 3 mm bolts holding the cover.
AutoPan Setup
The AutoPan models (AD1240/24A or AD1240/24PA) must
be set for the proper AutoPan ends stops. This is accomplished
by adjusting the Pan axis limit strikers to the desired end stop
positions, as above.
When the AutoPan signal is applied (24VAC ±10% to pin 6),
the unit continuously pans between the two end stops, until the
signal is removed.
