Installation: Motors Using Relays, Safety Disable Switch
PowerTouch Remote Control Systems - 814 Series (2 - 4) Functions
Manual C814.N2
WARNING!
If using any type of motor, such as a window motor, a ramp motor, a door
motor, or a winch motor - add a Disable switch to prevent the door or window circuit from
operating when vehicle is in motion.
A disable switch should be installed in many applications to deny operation of the motor
when a vehicle is in motion. However, due to changes in automotive electrical design and the
addition of computer controlled circuits, it is no longer advisable or safe to tap into or cut wires
to disable automotive factory circuits. To overcome this problem, you must install an electro-
mechanical switch which will determine gear position, thus safely disabling the circuit while the
vehicle is in motion. Below are three options for installing a Safety Disable Switch.
