Pelco Manual C585M-B (11/98) 21
4.0 OPERATION
In general, all controller operating controls are self-explanatory. All controls, except
the ON/OFF power switch, are center-off, spring return switches (momentary on-
off-momentary on.)
When using Aux 1-4 in the latching mode, operating the switch once will latch the
function and operating it again will unlatch the function.
The camera on/off switch is non-functional; the receiver is permanently in the ON
condition.
Reset causes latching functions to revert to the following:
1. Manual scan
2. Automatic iris
4.1 AUTO/RANDOM OPERATION
Auto scan and random scan modes are available when the A9000 Auto/Random
Scan plug-in module is installed in the Wiretron receiver. This module, when used
with the MPT8000 Series controller, allows control of pan and tilts. Refer to the
A9000 manual for installation and operation instructions.
Advantages of random scan:
1. Because the scan direction, scan period, and dwell period are unpredictable,
unauthorized activities or intrusions are discouraged.
2. Because of the reduced duty cycle, gear train wear, cable fatigue, drive motor
wear, and temperature rise are reduced. These factors contribute to system
reliability and increased equipment life.
