SW3-7 and SW3-8 Speed Control
The factory setting for speed control is SW3-7 OFF and SW3-8 OFF. This provides a
fixed output of 50Hz. If speed control is required on normal 24V AC pan/tilt units, some
on-site trial may be required to establish the best setting for the particular unit in use. If
the pan/tilt unit has internal phase shift capacitors connected, a single-phase setting
should be selected. Some units can be modified to remove the internal phase shift
capacitors to allow the Bi-Phase speed ranges to be used.

Motor Time Out
For all types of pan/tilt drives a motor time-out exists in software, i.e. should a pan/tilt run
to the end stop and the limit switch not shut the unit off, the software will stop the drive
after a period of four (4) minutes for any direction.

Tamper Alarm Input
The tamper alarm input can be used to secure the control cabinet and/or the camera
housing. The connections are made at PL10, and an open circuit between the two
terminals indicates an alarm condition. This will be detected by the motor control micro-
controller, which will pass a message to the CC-2000 communications controller. This in
turn sends a message to the MAXPRO-NetSystem Controller.
