12. Attach the faceplate trim to the back box by align-
ing the two serrated studs with two of the holes in
the edges of the back box and engaging the studs.
13. Operate the pan/tilt to verify that there are no ob-
structions or dragging cables within the back box
or dome.
4.4 CONNECTOR ASSEMBLY
To install and test the SB1900 Series enclosures you
may need to fabricate the interconnecting cable as out-
lined below. (Pretested wire harnesses, WH1900-06 and
WH1900-25, are optional cables for the SB1900 Se-
ries dome enclosures).
1. Strip back the cable jacket approximately 2 inches
and separate the individual conductors.
2. Attach spade lugs to each wire and mate BNC to
coax and camera sync.
3. Pop out a knock-out in one of the ends of the J-box
(on top of back box). Thread cable into J-box
through knock-out and attach each wire to the ter-
minal block, as marked beside terminal block, and
engage BNC connectors or video and camer sync.
4.5 ADJUSTMENTS
To adjust the pan/tilt limits, perform the following steps.
Refer to Figure 5 for limit stop locations.
CAUTION: Do not attempt to adjust limit
stops when the pan/tilt is in operation. Damage
to the equipment can result. Also, do not oper-
ate equipment without limit stops. Note that SL
models are supplied without pan limit stops,
therefore, no adjustments are necessary.
Factory pan limits are set to 0-355° and tilt limits are to
0-90° (horizontal to vertical). Under normal conditions,
the tilt limits should not have to be reset.
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 the actuator clicks. Lock the limit into posi-
tion. Replace the drive unit.
2. Pan to the desired left position, remove the drive
unit from the back box and adjust the pan limit
stop until the actuator clicks, and lock into posi-
tion. Replace the drive unit.
3. Pan to the right and left to verify the exact posi-
tioning.
4. The tilt limit is factory set at 0 to -90° travel (hori-
zontal to vertical). The tilt can be adjusted to any
point between horizontal and vertical; however,
under normal conditions the tilt limits should not
require adjustment.
5. To alter the factory set tilt limit*, bend the actua-
tor stops on the microswitches (see Figure 6).
Move the tilt table to the desired position and ad-
just the actuators until the switch clicks; lock into
position.
6. Tilt up and down to verify exact positioning.
* It should be emphasized that only very minor adjust-
ments should be made by bending the actuator attached
to the microswitch; and then, only for the reason of
bringing it within factory specifications.
