Table 2 CONFIGURATION OPTIONS:
ELECTROMAGNETIC BRAKE DRIVER (J1 Pin 20)
OPTION
DESCRIPTION OF OPERATION
0
Brake Driver disabled.
1
Electromagnetic brake used like a parking brake. The Brake Driver powers
the brake coil when the interlock switch closes, and opens it immediately
when the interlock switch opens. There is no delay, other than the specified
Brake Delay, between the Brake Driver being turned off and the interlock
switch opening.
2
Electromagnetic brake engages whenever the throttle is in neutral and the
vehicle is not moving. The Brake Driver turns on and disengages the brake
when a direction switch closes. The Brake Driver turns off, engaging the
brake, after the controller reaches neutral state
*
and the specified Brake
Delay time expires. With Option 2, the Brake Driver remains on after the
emergency reverse switch opens if a direction switch is still closed. The
Brake Driver turns off only after the specified Brake Delay when controller
reaches neutral state.
*
The interlock switch must be closed for the Brake Driver to energize the
brake coil and release the brake. The Brake Driver turns off, engaging the
brake, when the interlock switch opens and the Brake Delay time expires.
3
Electromagnetic brake engages whenever the throttle is in neutral and the
vehicle is not moving or after the emergency reverse switch closes and is
then released. During normal operation, Brake Driver Option 3 controls
braking as in Option 2. However, if emergency reverse is engaged, the
Brake Driver turns off, releasing the brake after the emergency reverse
switch opens and the Brake Delay time expires. After the emergency
reverse switch opens, the Brake Driver turns off even if controller is not in
neutral state.
*
The interlock switch must be closed for the Brake Driver to energize the
brake coil and release the brake. The Brake Driver turns off, engaging the
brake, when the interlock switch opens and the Brake Delay time expires.
4
Electromagnetic brake engages whenever the interlock switch is open (as
in Option 1) and also after the emergency reverse switch has been
released. The interlock switch must be closed for the Brake Driver to
energize the brake coil and release the brake. The Brake Driver turns off,
engaging the brake, when the interlock switch opens and the Brake Delay
time expires.
Also, if emergency reverse is engaged, the Brake Driver turns off,
releasing the brake after the emergency reverse switch opens and the
Brake Delay time expires. After the emergency reverse switch opens, the
Brake Driver turns off even if controller is not in neutral state.
*
*
The neutral state is reached when the traction throttle is in neutral, no direction
is selected (both direction switches open), and any braking is completed.
