5.1 SYSTEM TEST FOR MLZA6DT
1. Hook up the cable between the output connector
on the MLZA6DT and the input connector on the
lens (see Figure 4).
2. Connect the video cable from the camera to the
VIDEO LOOP-THRU on the rear panel and to the
monitor (see Figure 4).
3. Turn the power switch on the MLZA6DT to the
OFF position, and plug the power cord into a 120
VAC power source.
4. For MANUAL operation, put the power switch in
the MAN position. Observing the monitor, test for
proper operation of zoom, focus, and iris functions
with related switches on the front panel.
5. For Auto operation, put the power switch in the
AUTO/ON position. The IRIS switch should not
operate; ZOOM and FOCUS switches should op-
erate normally. Next, adjust the level of video
using the LEVEL knob on the front panel and
observing the monitor. As the video level is ad-
justed, the iris should open or close depending on
whether video display is bright or dark.
6. Test the control for fast and slow speeds of all func-
tions by turning the LENS SPEED knob on the
front panel and observing their operation as the
knob is adjusted.
