DESCRIPTION The Electronic Code Switch is designed for safe machine control and to help prevent unauthorized access use of the machine. If a machine is taken out of service, it is possible to block all functions except for the master code to reactivate the device. The ECS can be used as a simple switch without using PIN codes. This function is useful during machine maintenance and trouble-shooting. It can be connected through the seat switch to deactivate the vehicle after 3 minutes of inactivity.
