Setting the Starting Line Enhancer

 

 

If the S.F.O. mode is set to mode one the Starting Line Enhancer will be turned on, if the S.F.O. mode is set to any mode 

other than mode one, the Starting Line Enhancer will be turned off.  To set the Starting Line Enhancer Time, which is 
displayed on line 1 of screen 3, repeatedly press the Set Up key until the text 

S.L.E.

 is displayed on the left side of line 1.  If 

two dashes are being displayed, the Starting Line Enhancer is turned off.  If a number is being displayed the Starting Line 
Enhancer is turned on.  

When the Starting Line Enhancer is turned on, to enter a new time do the following.  Press the Next key until the selection 

arrows are positioned to the right of the S.L.E. time.  Then press and release the Clear key the selected display line will now be 
blank indicating the unit is ready to accept the new time.  Now using numerical keys enter the new time, leading zeros do not 
have to be entered.  For example if 01.00 for a S.L.E. 1 time was desired 100 would be entered on the keypad.  If less than four 
digits are entered for a time, pressing the Next key will act as an enter key and the leading zeros will displayed on the LCD.   
As the numbers are entered they are shown on the display, indicating the numbers are accepted and entered into memory.  If a 
mistake is made while entering the time, press and released the Clear key and reenter the time again.  

The Scrolling Arrow keys can also be used to change the S.L.E. time.  First make sure that the selection arrows are on the 

line to be changed.  If not change which line is selected using the Next key.  Once the desired line has been selected pressing 
and releasing the Up Arrow key will cause the time to increase by one.  While pressing and releasing the Down Arrow key will 
cause the time to decrease by one.  If the Up Arrow key is held down the time will scroll up and if the Down Arrow key is held 
down the time will scroll down.   

Note:  The S.L.E. output mode is controlled by the Throttle mode for Timer 2.  This mean if the Throttle stop is working 
backwards change the Throttle mode for Timer 2. 

Setting the Programmable  Throttle Stop Override (P.T.S.O.)

 

To set the P.T.S.O. amount, which is displayed on line 2 of screen 3, repeatedly press the Set Up key until the text 

P.T.S.O.

 is displayed on the left side of line 2.  If the P.T.S.O. is turned off, two dashes will be displayed on line 2.  If a 

number is displayed the P.T.S.O. is turned on and the number shown is the current P.T.S.O. time.  To turn the P.T.S.O. off 
when it is turned on, repeatedly press the Next key until the selection arrows are on line 2.  Then press and release the Clear 
key followed by the Next key.  To turn on the P.T.S.O. or enter a new P.T.S.O. amount repeatedly press the Next key until the 
selection arrows are on line 2.  Next press and released the Clear key the selected display line will now be blank indicating the 
unit is ready to accept the new time.  Now using numerical keys enter the new time, leading zeros do not have to be entered.  
For example if 1.00 for a P.T.S.O. amount were desired 100 would be entered on the keypad.  If less than four digits are 
entered for an amount, pressing the Next key will act as an enter key and the leading zeros will displayed on the LCD.   As the 
numbers are entered they are shown on the display, indicating the numbers are accepted and entered into memory.  If a mistake 
is made while entering the time, press and released the Clear key and reenter the amount again.  If a number greater than zero 
is entered, any number from 00.01 to 99.99 seconds, the P.T.S.O. will automatically be turned on. 

 The Scrolling Arrow keys can also be used to change a P.T.S.O. amount.  First make sure that the selection arrows are on 

line 2.  If not, change which line is selected using the Next key.  Once line 2 has been selected pressing and releasing the Up 
Arrow key will cause the time to increase by one.  While pressing and releasing the Down Arrow key will cause the time to 
decrease by one.  If the Up Arrow key is held down the time will scroll up and if the Down Arrow key is held down the time 
will scroll down. 
 

Setting Time Ranges for Timer 1 and Timer 2

  

 

To change the Time Range for Timer 1, which is displayed on line 3 of screen 3, or the Time Range for Timer 2, which is 

displayed on line 4 of screen 3, repeatedly press the Set Up key until the text 

Timer 1

 is displayed on the left side of line 3.  

For either Timer 1 or Timer 2 the Time range can be set either “Lo” or “Hi”.  The Time Range controls the resolution of the 
first and second stages times only.  The first and second stage times can be set to any number from 0.000 to 9.999 seconds 
when in “LO” Range and from 00.00 to 99.99 seconds when in “Hi” Range.  The settings for Timer 1 and for Timer 2 do not 
have to be the same.  However care should be taken to notice the decimal point location when entering a stage time.  To 
change a Timer Range press and release the Next key until the selection arrows are to the right of the Time Range to be 
changed.  Next press and release either an Up or Down arrow key, this will switch between “Lo” and “Hi” ranges.  The Range 
for Timer 2 can only be set if the S.F.O. mode is set to 2, if the S.F.O. mode is set to any other number other than 2, two 
dashes will be displayed for Timer 2 indicating that Timer 2 is turned off.
