530T Window Automation System

The 530T window automation system controls the operation of two vehicle windows in both the up and down

directions. The 530T automatically rolls up the power windows when the security system is armed, as well as pro-

viding “one-touch” operation in either direction. The 530T can also be used to vent or roll the windows

completely down with an auxiliary channel from the security system.

Before wiring the 530T, it is important to understand how different window systems work. A 12VDC motor must

have (+)12V on one of its wires and (-) chassis ground on the other in order for it to operate. Most window

switches are connected directly to the window motor with two wires. These two wires will either rest at (-)

ground, (+)12V ignition, or sometimes they will rest open. In any of these systems, the switch, when activated,

will send (+)12V to one wire and (-) ground to the other wire. Which wire gets (+)12V and which wire gets (-)

ground determines which direction the motor will roll the window.

The three window systems will be referred to in this manual as type A, B, or C. To determine which type of system

you have, turn the ignition on, check the power window wires at the switch with a meter to see what polarity

they rest at. If they rest at (-) ground, you have a type A system. This is the most common system. If they rest

at 12V when the ignition is on, you have a type B system. This system is used on many European vehicles. If the

wires rest open, you have a type C system. The wiring for the type A and type C systems is exactly the same,

however, the type B system differs slightly.

NOTE: If the vehicle is equipped with any type of factory automatic full-travel or “one-touch”

system on the driver’s window, there may be a relay or module in the driver’s door. Be sure to inter-

face with the wires between the module and the window motor.

530T Window Automation System The 530T window automation system controls the operation of two vehicle windows in both the up and down directions. The 530T automatically rolls up the power windows when the security system is armed, as well as providing “one-touch” operation in either direction. The 530T can also be used to vent or roll the windows completely down with an auxiliary channel from the security system.

Type A or Type C Windows Type B power window systems are common in many European cars, such as Mercedes Benz and Porsche. In the type B system, the power window wires will rest at (+)12V ignition and the switch will switch one of the wires to (-) ground to activate the window motor. The wire that switches to (-) ground determines which direction the window will move.
PAGE 3
Type B Windows Some window systems use either a central control module, or control modules in each door. These systems are less common than direct wired systems. These can be found in many newer Volkswagens, BMWs, Isuzus, Maximas and Grand Cherokees. If the vehicle has one of these systems, the 530T must be interfaced between the module(s) and the window motor(s). This often requires the wires to be run into each door. The 530T monitors the AC “noise” generated by the motion of the motor.

H1/3 BLUE Driver-Side Up Motor Input: Cut the driver-side up wire at the switch (see NOTE on page 1) and connect this wire to the motor side of the up wire. H1/4 RED (+)12V Constant, 20A Fused: Connect to a fused source of constant 12V. Make sure to connect this wire to a 12V source capable of handling high current draw, such as the ignition harness or the battery. H1/5 BLACK (-) Chassis Ground: Connect this wire to a paint-free surface on the vehicle chassis. Use a factory bolt if possible.

NOTE: If the security system does not have a ground-when-armed output, a negative lock pulse from the security system can be used to roll the windows up, as shown in the following diagram. H2/5 GRAY (-) Output During Activation: Connect this wire to an optional relay (P/N 610T) to bypass sensors which may trigger the security system during operation. This wire continues to output negative (-) ground for 5 seconds after the window motors have stopped.

Switch 5 Switch Input Polarity ON (-) OFF (+) Dipswitch #5 controls the polarity that the 530T switch input wires will respond to. For type A and type C systems, it must be set to the OFF (+) position. When the switch is in the off position the 530T responds to (+) positive inputs on its switch wires. If your vehicle has a type B system, this switch must be set to the ON (-) position, so the 530T will respond to (-) negative inputs on its switch wires.

NOTE: If “one-touch” operation is desired from the passenger-side switch, the passenger-side wires must be run into the passenger-side door and interfaced between the passenger-side switch and the motor. NOTE: If using a delayed auxiliary channel from the security system, such as channel 2, to control windows down operation, the transmitter button will need to be pressed for 1.5 seconds to vent the windows or 4.5 seconds to roll the windows all the way down.
