5 Wire Reversal Rest At Ground Systems differ from the Negative and
Positive Pulse systems as there are no relays
or doorlock control unit. In this type
of system, the switches themselves supply the positive voltage directly to the
doorlock actuators, and, more importantly, provide the return ground path. The
important thing to rememberis the wires
in this system rest at ground, which means
that the wires must be "opened",
or cut, to make the connections.
Examine the wires
on the back ofthe switch. Normally five wires will be found-
one will be constant 12 volts positive, regardless
ofthe switch's position; two wires
will be grounded regardless
of the switch's position. Of the two remaining wires,
one will show
12 volts positive when the switch is pushed to "lock", and the other
will show 12 volts positive when the switch is pushed to "unlock".
The two later wires are both routed to the doorlock actuators and are connected
to either
end of the actuator's motor winding. When the switch is pushed to one
position, one
of these two wires will have 12 volts. This voltage flows through the
wire to the actuator's motor winding, and since the other wire is still resting
at
ground an electrical circuit is completed. When the switch is pushed to the opposite
position the electrical flow is reversed.
Oncedetermined, the correctwires mustbe cut. Notice in the following diagram
that the driver's switch is the primary switch and referred to as the "switch" wires.
The wires that go to the secondary switch are referred to as the "motor" wires. Even
though the cut is made between the switches, the two sides are still correctly called
the "switch" and the "motor" sides, with consideration
of "Primary" and "Second-
ary" switch.
