The C3pump controller, which offers a combination of AC
traction and DC pump drives, is an extension of CurtissWright’s high-performing, compact and cost-effective C3
family, but with all the specialist features needed for efficient
and precise control of modern day stacker trucks. Flexible,
yet simple programming means the controller is compatible
with all types of AC induction and DC series motors, while a
dedicated thermistor input allows traction motor temperature
and the power to the motor to be reduced if it is becoming too
warm.
The C3pump features up to eight dedicated digital inputs that
can be individually switched to 0V, open-circuit, B+ or a
combination of these options to provide the active state. The
controller also accepts multiple throttle types, including 2- or
3-wire resistive and voltage. CAN tiller compatibly is provided
as standard, offering vehicle OEMs maximum input flexibility.
Five, 2A outputs allow for control of the line contactor, hold
and proportional lower valves, a horn coil, plus an electromagnetic brake. All outputs are protected against wiring
errors and contain coil suppression circuits, meaning external
diodes are not required.

To ensure maximum efficiency, the C3pump employs an
intelligent Hill-Hold function that only takes power from the
battery if the vehicle starts to roll. As soon as it is detected
that Hill-Hold is not required, then no further power will be
consumed. Traditionally, application of a brake switch has
been needed to provide this function.
In addition to on-board LEDs that can communicate basic
status and diagnostic information, the controller includes two
service timers – one for keyswitch hours and one for
operational ‘active’ hours. These can be set by an OEM or
service agent, thereby ensuring an appropriate maintenance
regime. After a service is complete, the timers can be set to
the next service interval.
The innovative construction methods employed by the
C3pump ensure reliable and repeatable assembly of the
electronic enclosure, which results in consistent protection of
the electronic circuits from the environment and efficient
transfer of heat to the baseplate. The design is compliant with
all relevant international legislation and takes into account
critical dimensions as defined by UL.
