FCS-4
Light emitting diodes (LEDs)
When operated in the forward direction the LEDs light. They
are available in several different versions (differing in colour,
size, form, luminosity, maximum current, voltage limits). The
longer lead of wired LEDs is always the anode (positive pole).
With SMD-LEDs the cathode normally is shown by a mark on
the housing.
Light emitting diodes should always be connected via a series
resistor which limits the current and prevents failure. With
circuits designed for the connection of LEDs the series
resistors are often integrated on the circuit board.
Reed contacts
Depending on their version reed contacts fulfill the task of a
closer or a change-over switch. They respond to a magentic
field, thus making possible contactless switching operations.
They consist of a glass bulb filled with a protective gas.
Sealed in the glass bulb are two or three reeds made of a
magnetic material. When bending the legs the glass bulb they
can be easily damaged through mechanical strain.

Mounting the FCS-4

Preparation
Open the housing of the vehicle. Locate the position for the module.
Disconnect all connections from the accumulator batteries, the motor and
the mounted reed contact except for the wire to the charging contact.
Follow the connection diagram fig. 2 (page II in the centre of this
handbook) and the special features of the addional components.
In many vehicles the resistor R7 shown in the connection diagram is
mounted into the lead-in wire to the motor. The resistor has to be
connected to the plus pole of the accumulator batteries if not yet
mounted that way. If there is no resistor, R7 is not applicable.
