Curtis 1253 Manual, Rev. F
from the hydraulic system if a controller or wiring fault results in battery power
being applied to the motor inappropriately.
e 1253 provides a low-side contactor coil driver (at Pin J1-12) for the
main contactor. e driver output is rated at 1 amp and is short-circuit protected.
It is recommended that a coil suppression diode be included, as shown in the
wiring diagrams. is protects the contactor coil driver from inductive voltage
kickback spikes when the contactor is turned o.
Keyswitch and Interlock Switch
e vehicle should have a master on/o switch to turn the system o when not
in use. e keyswitch input provides logic power for the controller.
e interlock switch, which is typically implemented as a seatswitch or a
hand/foot activated deadman switch, provides a safety interlock to ensure that
an operator is present in order for the system to run.
e keyswitch and interlock switch provide current to drive the main
contactor coil as well as the controller’s internal logic circuitry, and must be
rated to carry these currents.
Speed Select Switches
ese input switches can be any type of single-pole, single-throw (SPST) switch
capable of switching the battery voltage at 25 mA.
Reverse Polarity Protection Diode
For reverse polarity protection, a diode should be added to the control circuit.
is diode will prohibit main contactor operation and current ow if the battery
pack is accidentally wired with the B+ and B- terminals reversed. It should be
sized appropriately for the maximum contactor coil current required from the
control circuit. e reverse polarity protection diode should be wired as shown
in the standard wiring diagrams (Figure 3).
Circuitry Protection Devices
To protect the control circuitry from accidental shorts, a low current fuse (ap-
propriate for the maximum current draw) should be connected in series with
the battery feed to the keyswitch. Additionally, a high current fuse should be
wired in series with the main contactor to protect the motor, controller, and
batteries from accidental shorts in the power system. e appropriate fuse for
each application should be selected with the help of a reputable fuse manufac-
turer or dealer. e standard wiring diagrams (Figure 3) show the recommended
location for each fuse.
