Fortress Technologies FS-50 manual Timed Crank Mode, HOW to USE this Feature

TIMED CRANK MODE

As an alternative to Tach or Tachless mode, “Timed Crank” provides an additional 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 with this mode. 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. SEE OPTION PROGRAMMING CHART FOR SETTINGS.

HOW TO USE THIS FEATURE:

1.Go to the “Programmable Options” section, and set Option #16 to “Pre-Set". (It is normally set to “Tach Monitor”)

2.With “Pre-Set” Cranking time 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 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 #21 and change the crank time setting to a longer value. The values are as follows: 0.5, 0.75. 1.0, and 1.5 seconds.

WARNING: This method of starting the vehicle is not as reliable as using regular “Tach” or “Ultra-Smart” Tachless modes. This method should be used only in the event that a tach wire cannot 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 1st attempt and may require a 2nd try, 3rd try, or may not start at all if unsuccessful after 3 attempts.

∙In warm weather when your vehicle may start very quickly, “Timed Crank” mode may tend to over-crank the starter.

∙The only way to possibly correct the above issues is to go to the Option #21 and adjust the cranking time. When in “Timed Crank” mode, the cranking time can only be adjusted manually through option #21. When using Ultra-Smart Tachless or Regular Tach modes, cranking time is adjusted automatically.
