8.11 WINDOW WINDING CONTROLLER
INTRODUCTION:
Power window system consists of controller
(including relays), low current switches & Window
winding Regulator Motor.
Window winding controller is an integrated control
which controls the movement of all four windows .
Controller senses the signal from low current
switches and operates the window winding motors
according to switch position (Manual UP/ Manual
Down/Auto Down). At the same time controller also
monitors the window position. When window has
reached either of the end position, supply to motor
is cutoff thereby protecting the motor from
overheating. Whether the window is moving or has
reached the end position is decided by monitoring
the motor current.
Running Current: Current drawn by motor while
the window is moving up or down.
Locking Current: Current drawn by motor when
the window has reached the end position and
thereby motor also stops running and locks.
Locking current is much higher than running
current. Controller is programmed for maximum
permitted Running Current and Minimum permitted
locking current.
XT VARIANT (XT 4x4, XT 4x2, XTA 4x2)
OTHER VARIANTS (XMA 4X4, XMA, XM, XE)
As long as the controller senses the motor current
is below the maximum running current, it allows
motor to operate but the moment it senses the
motor current is above the minimum locking
current then within ‘t’ seconds controller will stops
the motor supply.
At a time one or more than one or all
windows can be operated together. Window will
operate in mode respective to its switch operation
– MU (Manual up), MD (Manual Down), AD (Auto
Down). Each window operation is monitored
independent of other windows.
LOCATION:
It is located beside HVAC unit (on RH side). The
Orientation of window winding controller is vertical
with connector facing downwards.
Location of controller is same for all variants.
