This new feature provides an easy method of starting the vehicle without locating an exact tach wire. It uses a timed
cranking output combined with the use of the Red/White tach wire as an engine ON/OFF monitor. The Red/White Tach
wire must still be used in this mode of operation. THIS FEATURE MUST BE PROGRAMMED BEFORE USE! THERE
ARE 2 LEVELS of programming required: First, set the system for "Timed Crank" operation, and secondly you may need
to adjust the amount of cranking time. There are 4 different crank times available for use.
PROGRAMMING CHART FOR SETTINGS.
HOW TO USE THIS FEATURE:
1. Go to the "Programmable Options" section, and turn ON Option #15 "Timed Crank". (It is normally on Tach Monitor)
2. With "Timed Crank" turned ON, you will STILL have to connect the Red/White Tach wire to a tach source on the
engine. The Red/White Tach wire becomes a simple "Engine Monitor". Although the unit will not be using the
Red/White wire to start the motor, it will be using this wire to determine whether the motor is running or not. This is a
mandatory connection. A "crude" or "less exact" tach source can be used only when in "Time Crank" mode.
3. Using the vehicle key, start the engine a few times to get a "feel" of how long the cranking time is. Once the "Timed
Crank" mode is turned on, the default cranking time is set to a default of 0.50 seconds. We recommend beginning
with this setting. Try a remote start and see if the cranking is appropriate for your vehicle
4. If 0.50 seconds is not an appropriate starter cranking time, then go to Programming Option #16 and change the crank
time setting to a longer value. The values are as follows: 0.5, 0.75. 1.25, and 1.5 seconds.
WARNING: This method of starting the vehicle is not as reliable as using regular "Tach" mode. This method
should be used only in the event that a tach wire can not be located using the normal tach programming and
tach finder. When using this method, there may be certain operating anomalies requiring seasonal adjustments.
These are, but not limited to:
• Starter may under-crank in extreme cold weather. Vehicle may not start on 1
rd
or 3
try.
• In warm weather when your vehicle may start very quickly, "Timed Crank" mode may tend to over-crank the
starter.
• The only way to correct the above issues is to go to Option #16 and adjust the cranking time.
• When in "Timed Crank" mode, the cranking time can only be adjusted manually through option #16. When
the RS900/999/901 system is in Smart Tachless or Regular Tach Learning mode, cranking time is adjusted
automatically.
