Back-up Feature
If the P.B. Mode is set to 1, 3, or 4, a button
connected to the P.B. 2 input can be used to back-up the
vehicle without starting a delay cycle. The advantage of
using a Back-up button over a bypass button is the current
for the Transbrake solenoid does not pass through the switch.
It is possible to wire more than one switch to the P.B. 2
input. Example, a toggle switch could be used for backing
up and then a separate push-button could be used for
Tapping up.
Note: If a toggle switch is going to be used to activate the
back-up feature, care must be taken to remember to
turn off the switch to avoid damage to the solenoid.
If the P.B. Mode is set to 5 the button connected to
the P.B. 2 input can be used to back-up the vehicle without
starting a delay cycle. Press the button to engage the
Transbrake to back-up. When done press the CLEAR key on
the keypad to release the Transbrake without starting a
timing cycle. If the S.L.E. is being used and the starting line
feature is turned, the S.L.E. will also turn on when backing
up.
Bypass Button
If Button 2 is not going to be used to back-up the
vehicle, a bypass button can be used. To wire in a bypass
button take one wire from your button and connect it to the
Power terminal on the Mega 475. Then connect the other
wire from the button to the Transbrake terminal on Mega
475. The Bypass Button will engage the Transbrake without
starting a timing cycle.
Note: The button and wiring used for the bypass button will
need to be able to handle the current of the
Transbrake solenoid.
