General
This section describes the AC Motor Controller.
Procedures are outlined for controller programming
and troubleshooting.
SAFETY PRECAUTIONS
WARNING
Disconnect the battery and separate the
connectors before opening the compartment
cover or inspecting or repairing the electrical
system. If a tool causes a short circuit, the high
current flow from the battery can cause personal
injury or property damage.
All checks, adjustments, and repairs in the drive
unit compartment are done with the compartment
cover removed. Remove the drive unit compartment
cover for access to the electrical components.
WARNING
The capacitor in the transistor controller can hold
an electrical charge after the battery has been
disconnected. To prevent electrical shock and
personal injury, discharge the capacitor before
inspection or repairing any component in the
drive unit compartment. Wear safety glasses.
Make certain the battery has been disconnected.
DO NOT use a screwdriver to discharge the
traction motor controller.
CAUTION
To avoid controller damage, always disconnect
the battery before disconnecting any cables from
the controller. Discharge the capacitor, and never
put power to the controller with any power wire
disconnected. Never short any controller terminal
or motor terminal to the battery. Make sure to use
proper procedure when servicing the controller.
The following steps must be followed to discharge
the capacitors before any checks or repairs are
performed on the controller or any part of the
electrical system.
1. Block the wheels so that the truck will not roll
or block the truck so that the wheels are off the
floor. See
•Periodic Maintenance 8000SRM1510
for lift truck model A290
2. Turn the key switch to the OFF position and
disconnect the battery.
3. Discharge the capacitors in the controller by
connecting a 100-ohm, 25-watt resistor across
the controller's B+ and B- terminals using two
insulated jumper wires. See Figure 1.
NOTE: DO NOT use any other method of
discharging the capacitors. Remove the 100-ohm,
25-watt resistor before reconnecting the battery.

Description
AC MOTOR CONTROLLER
The controller is a solid-state, AC motor controller.
It can control the traction motor, brake, and hy-
draulic system. The controller receives inputs from
the control handle by serial communication, and di-
rect inputs from other switches depending on
model. These may include the following:
• Key switch
• Control handle arm position switch
The controller directly controls the traction motor,
lift pump motor, main contactor, and the brake.
The motor controller controls the speed of the trac-
tion motor and the hydraulic lift pump motor oper-
ation. The controller software provides self diagnos-
tics which are accessed by means of a Curtis hand-
set.
PRINCIPLES OF OPERATION
The Traction Motor Controller uses a sophisticated
microprocessor to control the logic and operation of
the controller, eliminating the need for forward and
reverse contactors. The controller has many pro-
grammable features, including maximum speed, ac-
celeration rate, neutral braking, and braking cur-
rent limit. The controller includes a full range of
features as well as diagnostic and setup capability
for reliable operation.
NOTE: There are no user-serviceable parts in the
Curtis controller. No attempt should be made to
open, repair, or otherwise modify the controller. Do-
ing so may damage the controller and will void the
warranty.

INSTALL
1. Make certain the mounting surface for the trac-
tion motor controller is clean. There should be
no dirt between the contactor panel mounting
plate and the traction motor controller.
2. Connect wires and cables to controller termi-
nals. See Figure 2.
3. Refer to Programming Controller for setup of
the controller.
The motor controller controls the speed of the trac-
tion motor and the hydraulic pump motor opera-
tion. The complete unit must be replaced if correct
troubleshooting methods show that the unit is dam-
aged.
PROGRAMMING CONTROLLER
The controller can be programmed using a 1311
handset. The areas that can be programmed are lis-
ted in Table 1 along with the adjustable ranges.

1311 Programmer Handset
DESCRIPTION/FEATURES
The programmer handset is a handheld tool that
allows the user to program, test, and diagnose the
traction motor controller. See Figure 3. It has been
designed for ease of use with a menu navigation
key, a data increase/decrease key, and 3 bookmark
keys to control all programmer functions.
The display window contains a 7-line, 128 × 64
pixel LCD screen that is capable of displaying both
text and graphics simultaneously. The window is
visible in most lighting conditions and can be adjus-
ted using the programmer setup menu.
The programmer is menu driven and accesses sub-
menus by pressing the menu navigation key.
When the programmer is connected to the motor
controller, all current motor controller information
is uploaded into the 1311 programmer handset and
ready for viewing. This upload is used by the pro-
grammer to generate menu items that will be dis-
played by the programmer.

Display (BDI)/Hourmeter
The 8-character LCD on the Display provides a con-
tinuous sequence of hourmeter, battery state of
charge, and fault messages. See Figure 18. Fault
messages are displayed using fault codes.
Figure 18. BDI/Hourmeter
Fault Codes
The Curtis controller has a Status LED built into it
and can be seen through a window in the label on
top of the controller. This Status LED displays
fault codes. During normal operation, with no
faults present, the Status LED flashes steadily on
and off like a heartbeat.
Fault codes may intermittently appear during
truck use. These signals may be sent as a result of
power loss to the controller from the battery. Turn-
ing the key switch OFF and then ON again will
usually clear these fault codes. If the codes remain
after cycling the key switch, the lift truck must be
serviced.
If these intermittent faults continually appear, per-
form the following checks:
• Check for loose cable connections at the bat-
tery cable connectors.
• Check for loose wiring and wire connectors at
the controller.
• Check for loose cable connections at the bat-
tery.
• Check battery cells for proper voltage and
state of charge.
If a loose wire or connection if found, make the nec-
essary repairs before returning the truck to service.
Fault codes may also intermittently appear after
the battery has been changed. If the BDI indicator
will not reset, this may indicate that the battery is
not properly charged. Always install fully charged,
properly functioning batteries to the lift truck.
NOTE: Minimum reset voltage for the BDI is 25.2
volts (open cell), specific gravity should be approxi-
mately 1.250 per cell.
