The Terminal Strip
+12VDC Terminal:
Connect the +12VDC terminal to a sw12 Volt source with enough amperage
capable of driving all outputs at the same time.
Transbrake Terminal:
Connect the Transbrake terminal to the Transbrake solenoid.
Connect the low side of the 2-Step here, if used.
Ground Terminal:
Connect the Ground terminal to the Neg. terminal on the battery or to good steel
ground,
not aluminum.
PB-1 Terminal:
In Push-button Mode 3 the push-button connected to PB-1 terminal is used
to control the primary delay and the secondary delay in sequence. In Push-button Mode 1 & 2
the push-button connected to PB-1 terminal is used to control the primary delay only.
PB-2 Terminal:
In
Push-button Mode 2 the push-button connected to PB-2 terminal is
used to control the secondary delay only.
In Push-button Mode 1 & 3 this terminal can be used for a Tap
pushbutton connection. After a Transbrake push-button has been released, every time the Tap push-button is
depressed a programmable amount of time is either added to, or subtracted from, the first delay time started until the
transbrake is released.
Throttle Stop Terminal:
Connect throttle stop wire to this terminal. This can be used as a
starting line enhancer or down track throttle stop controller.
This is only on the
MEGA
75
w/ 4 Stage Timer.
