17. ELECTRIC AWNING WINDOW

The electric awning windows are connected
directly on the batteries 24 V DC terminal block.
As a result, they can be operated regardless of
the state open or close of the master switch.
However, the circuit is protected with fuse F41
(10A) located in the front service compartment.

17.1 OPERATION

Opening sequence: switch is set to the OPEN
position. Window latch solenoid SOL1-A and
SOL1-B are turned on along with M1 window
motor. Once the latch is open, proximity switch
PROX1 is de-activated, turning sol1-A and
SOL1-B off.
Closing sequence: switch is set to the CLOSE
position, turning on relay R1 which turns on M1
in reverse polarity, closing the window. Once the
window is closed, PROX1 is activated, turning on
SOL1-A and SOL1-B in reverse polarity latching
the window closed.
