Wiper Control System

The Mega-Guard Wiper Control System (WCS) controls up to 9 windshield wipers.


The Mega-Guard Wiper Control System (WCS) controls up to 9 windshield wipers. Each wiper has its own on/off  button and fore and aft wipers are grouped together for simultaneous on/off control.

Separate Aft and Fore buttons are available for Low/High Speed, Heating and Washing functions. In Low speed mode the interval can be varied with the Interval+/Interval- pushbuttons.

The wipers are synchronized with each other. The washing function includes spraying, wiping and purging. 

The Mega-Guard WCS supports multiple Operator Panels. A typical lay-out includes two Wiper Operator Panels: one installed in fore bridge and one installed in aft bridge.  The Operator Panels are inter-connected by a redundant Ethernet network.

System lay-out and operation

The Mega-Guard WCS consists of the following items: 

  • Wiper Operator Panel for flush panel mounting in bridge console
  • Wiper Controller for din-rail mounting inside bridge console
  • I/O Cable connecting the WCS Operator Panel with WCS Controller

The WCS Operator Panel is operated through a user friendly 5,7" touchscreen for intuitive operation and monitoring. This Operator Panel is available in two different versions, a panel with a metal front for commercial and navy ships and a panel with glass front for mega yachts..

The WCS Controller is DIN rail mounted inside bridge console and the window wiper connections are directly connected to this Controller. In addition, the WCS Controller is equipped with manual on/off switches for each individual wiper. The WCS Controller should be mounted in such a way that it can be reached without using tools in order to make use of this function.

The I/O Cable with length of 3 or 5 meter, inter-connects the WCS Operator Panel with the WCS Controller.
