YELLOW
(+) Glow-
plug Light
input
This positive input will monitor the Glow Plug Light in Diesel Mode: it will
wait until the Glow Plug Light goes out to crank the Engine. Connect to
the side of the Glow Plug Light that is positive when the Light is on.
Note
: In Diesel Mode there is a 18-sec. crank timing delay (or
approximately 25-sec. if the run time is set to 30 min.): if the Glow Plug
Light is still on after the delay expires, the Module will proceed to start
the Engine.
(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. The Module will only accept
positive Glow-plug input signals, if the signal is negative, use a
relay to invert its 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.
•
Minimum waiting time is 3 seconds.
•
Maximum waiting time is 25 seconds (approx.).
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:
•
Connecting the Glow-plug input wire of the Module
to Ignition
will
hold the ignition
ON
for the maximum waiting time of approximately
25 sec. (recommended).
•
Keeping the Glow-plug input wire of the Module
unconnected
will
hold the ignition
ON
for the minimum waiting time (3 sec., not
recommended in very cold environments).
Connect the Glow-plug wire to the Ignition wire only after Tach has been
programmed (i.e.: Connecting the Glow-plug wire is one of the very last
steps in the installation process).
