FCS modules English
Connection to the supply voltage
Connect the connecting point X2 to the plus pole of the accumulator
batteries and the minus pole of the accumulator batteries to the
existing switch S of the vehicle. Connect the second pole of the switch
to the connecting point X1.
Caution: The module should not be connected the wrong way
!
round. Otherwise it will be damaged when put into operation!
Connection of the existing reed contact
The existing reed contact has three connecting points, one at side A
and two at side B. Connect the connecting point at side A to the
connecting point X1 and the existing switch S.
In order to check which one of the two connecting points of side B you
have to connect to the module, connect temporarily the plus pole of the
motor to the plus pole of the accumulator batteries and the minus pole
of the motor to one of the two connecting points at side B of the reed
contact. If the motor does not run with this connection, you have to
connect this connecting point to the plus pole of the motor and the
other connecting point of the reed contact with the connecting point X9
and the enclosed resistor R10. If the motor runs with this connection,
you have to make the connections the other way round. Connect the
second side of the resistor R10 to the connecting point X3.
Connection of the motor
Connect the enclosed diode 1N4148 to the connections of the motor.
Observe the polarity of the diode. Then connect the minus pole of the
motor to the switch switching the minus pole of the accumulator
batteries and to the connecting point X1. Next connect the collector (C)
of the enclosed transistor BC 327 to the plus pole of the motor, the
basis (B) to the connecting point X7 and the emitter (E) to the resistor
R7. If there is no resistor R7, connect the emitter directly to the plus
pole of the accumulator batteries.
