12 YELLOW (+) Glow-Plug
input
In diesel mode, this positive input will monitor the
glow plug light: it will wait for up to 30 seconds until
the glow-plug light goes out before allowing the
module to proceed to cranking the engine. Connect
to the side of the glow-plug light which is positive
when the light is on.
Note:
the module will nevertheless proceed to
cranking the engine if the glow-plug light is still on
after the 30-sec. delay (25 sec. when the run time is
set to 30 min.).
A Note on the Diesel Glow-plug Indicator Light:
(Also known as the “wait-to-start light”.) The purpose
of the glow-plug circuit on diesel vehicles is to pre-
heat the combustion chamber before the vehicle is
started.
When a remote starter is installed on a diesel
vehicle, the glow-plug section of the ignition circuit
must be activated and allowed to operate before the
vehicle is remote-started. For that purpose, the glow-
plug input wire of the module must be connected to
the glow-plug indicator light of the vehicle.
Caution!
The module will
only
accept
positive
glow-
plug input signals, therefore negative glow plugs
should only be connected using relays to invert the
polarity.
A diode must be added between the negative glow-
plug trigger on the relay and the negative glow-plug
wire of the car. This is to prevent feedback effects on
the glow-plug indicator light on the instrument
cluster: the light on the dash would come on because
of the feedback, even though the circuit is off.
When the user remote-starts the vehicle:
•
The module will power up the Ignition circuit and
wait to engage the starter motor while the glow-
plug indicator light is still on.
•
The module will engage the starter motor as
soon as the glow-plug light (+) goes out.
o
Minimum waiting time is 5 seconds.
o
Maximum waiting time is 30 seconds.
If no glow-plug wire is found on the vehicle, the glow-
plug input on the module may be “timed out”. The
module will power up the ignition and glow-plug
circuits and simply wait for the time-out before
starting:
