INSTALLATION
Window wiper kits in the WW57 Series are designed to operate with an AC voltage to turn
on the wiper. However, the kits must be modified to use +5 to +10 VDC to turn on the wiper
when the kits are used with Pelco’s receivers.
If you are going to use a Pelco receiver, proceed to the
Window Wiper Kit Modification
sec-
tion.
If you are going to use equipment that provides AC power to control the wiper, proceed to
the
Window Wiper Kit Installation
section.
WINDOW WIPER KIT MODIFICATION
Modify your wiper kit if it is to be operated from any of the following Pelco receivers:
CX9000 Series
WX8000 Series
LRD41 Series
ERD97P21-U with the ERD97P-AUX option board
This modification only changes the voltage that is required to turn on the wiper. The wiper
motor still requires AC voltage (refer to Figure 1).
To modify a kit:
1. Remove the circuit board cover from the wiper motor/control assembly and remove the
circuit board (PCB9000275 Rev. E). Refer to Figure 10 for parts locations.
Refer to Figure 2 for steps 2-5.
