Anti-Trap Protection

Window anti-trap detection feature is only active in the one touch and convenience close modes of operation. If the window switch is pushed/pulled and held, the anti-trap feature will not function. The rubber pressure guard located at the top edge of each door frame consists of 2 contact strips that close when subjected to pressure. This provides anti-trap detection and signal generation to the general module. When the contact strip closes, the window immediately reverses direction as with previous anti-trap systems. The contact strip does not require that the anti-trap feature be initialized prior to operation. The pressure sensor finger guard has a resistance of 3.0 k/ohms and it is monitored for an open circuit. When pressed, the monitored resistance changes to less than one k/ohm. Faults with the anti-trap system require that the window switch be held to close the window.
