Menu #3 - Remote Start Options - Viper 7900 Installation Manual

Channel Five can be programmed for these output configurations. The unit is set to the default validity
output. To change the configuration, use the two-chirp setting to toggle through the different configura-
tions. Refer to feature 2-10 for additional detail.

detail.

menu #3 - remote start options

3-1 ENGINE CHECKING ON/OFF: In the default setting the remote start will monitor either the vehicle's
tach wire or voltage depending on the programming of feature 3-2. If programmed OFF the vehicle will crank
for the programmed crank time (feature 3-5) and will not verify with tach or voltage that the car is running.
In the OFF setting, if the vehicle fails to start, the ignition can stay on for the entire run duration. Using
tach or voltage check is always recommended if possible.
3-2 CHECKING TYPE TACH/VOLTAGE: Selects the method of engine monitoring. If set to TACHOMETER the
unit will reference the learned tach signal to disengage the starter. In addition it will monitor the RPM and
shut down if the engine RPM is too high or too low. When set to VOLTAGE, the unit will crank the starter
for the programmed time and then attempt to sense that the engine is running by detecting an increase in
voltage. The threshold for the voltage check is selectable in feature 3-6.
3-3 RUN TIME 12, 24, 60 MINUTES:
Selects the time in minutes that the system will operate the
engine until the system "times out". This is the maximum operation period and the system may be shut
down using a shutdown at any time. Using the Bitwriter®, the run time can be programmed for any duration
from 1-60 minutes.
3-4 PARKING LIGHTS FLASHING/CONSTANT: In the default setting, the unit will flash the vehicle's parking
lights (if connected) while remote started. The constant setting will turn the parking lights on solid for
the entire run duration.
3-5 CRANK TIME 0.6/0.8/1.0/1.2/1.4/1.6/1.8/2.0/4.0 SECONDS: If the unit is programmed for no
engine checking or voltage sense, the crank time must be set to the appropriate duration. The default
setting is 0.6 second. If a different crank time is desired, select feature 3-5 and select either 0.6 second by
using the one-chirp setting or toggle through the higher settings by using the two-chirp settings.
3-6 VOLTAGE CHECK HI/LOW: This feature only functions when programmed for voltage sense. Some
vehicles have many accessories, which are turned on when remote started. In these vehicles, the variation
of voltage between the engine off and the car running is very small and the remote start unit may "think"
the vehicle has not started. This can cause the remote start to shut-down after the car has been started.
If this happens program this feature to the LOW position.
