 The Terminal Strip 

 

 

+12VDC Terminal:

  

Connect the +12VDC terminal to a sw12 

 

Volt source with enough amperage capable of driving the transbrake.  

 

(Using an in-line fuse just large enough to handle the current draw 

 

of the transbrake solenoid, 

normally 15 Amps.,

 is recommended.)

 

 
Transbrake Terminal:

  

Connect the Transbrake terminal to the 

 

Transbrake solenoid.  Connect the low side of the 2-Step, the red 

 

wire, here if used.  

 
 

 

When entering new information into the unit, there  

 

 

must be a number (0-9) in every valid space on the 

 

 

display or the transbrake terminal will not function.

 

       

 

Ground Terminal:

  

Connect the Ground terminal to the Neg. terminal 

 

on the battery or to a good steel ground, not aluminum. 

  

Button-1 Terminal:

  

In single Push Button Mode the push button 

 

connected to Button-1 terminal is used to control the primary 

 

delay and the secondary delay in sequence.  In dual Push Button Mode 

 

the push button connected to Button-1 terminal is used to control 

 

the primary delay only.  

 

Button-2 Terminal: 

 

In single Push Button Mode the push button 

 

connected to Button-2 terminal is used to control the recovery 

 

if turned on.  In dual Push Button Mode the push button connected to 

 

Button-2 terminal is used to control the secondary delay only.   

 

Tap  Terminal:

  

If taping up or down is desired connect a push 

 

button to the Tap terminal.  This allows you to subtract or add a 

 

programmable amount of time from the first delay time started 

 

every time the Tap Push Button is depressed.   

Note:

   In single Push Button Mode the Tap Up or Down only affects the 

 

primary delay and has no effect on the secondary delay.
