Specifications

MPW080E,
MPE060E,
MTR005E, and
MPC060E = Approx.
14.0 ohms
MPW065E =
Approx. 4.0 ohms
If open or shorted,
replace coil.
4. Check voltage at pin
#J1-12 and pin
#J1-20. Voltage
should be less than
battery voltage.
5. If brake still cannot
be energized, replace
controller.
Logic
Controller will output battery volts at pin #J1-20 when brake switch is closed. The
controller monitors the current in the brake circuit and will fault if overcurrent occurs.

Possible Causes and Test
Procedures
1. Ensure the cable is
connected to the J2 plug
on the controller.
2. Verify all pin connections
are tight and making
contact.
3. Verify correct connector
wiring.
4. Check continuity of the
wires running from the
controller to the control
handle logic card.
Verify continuity while
rotating the control
handle arm from side to
side.
5. Check for control handle
wiring grounded to the
truck frame.
6. Check for correct
operation of the control
handle logic card.
Use handheld
programmer to verify
signals from the control
handle logic card are
being received by the
controller.
7. Improper parameters on
software, use handset to
verify parameters.
8. For testing procedures
refer to Control Card
Functional Test in this
section.
Circuit Description
Logic
The control handle logic card communicates with the controller through the cable
between the logic card and the J2 connection on the controller. All signals for speed,
direction, emergency reverse, horn, and lift/lower are sent to the controller over this
cable.
