Curtis PMC 1297 Manual

Preliminary on Verso page is set with right edge at 7 and 7/8,
and the top (as on the Recto page) at 1/4.
WIRING: Auxiliary Driver
(
REQUIRES
MULTIPLEXER
)
The 1297 controller provides an auxiliary driver at Pin 8. This low side driver,
designed to energize a contactor coil, can be used to perform a variety of
functions—such as engaging a brush motor. The output is rated at 2 amps, is
overcurrent protected, and the turn-off is voltage clamped. The recommended
wiring for an auxiliary contactor coil is shown in Figure 4. The contactor coil
or driver load should
not
be connected directly to B+. The on/off switch for the
auxiliary driver is located on the multiplexer.
WIRING: Coast and Pick
(
REQUIRES
MULTIPLEXER
)
When a multiplexer is used, J1 Pin 24 is the Coast input—as shown in Figure 4,
page 10. When the tiller is locked in the Coast position (activating the Coast
switch), the multiplexer’s Pick switch can be used to drive the vehicle a short
distance forward. When the Pick switch is released, the vehicle coasts to a stop.
WIRING: Emergency Reverse
To implement the emergency reverse feature, J1 Pin 6 (the emergency reverse
input) must be connected to battery voltage. Emergency reverse is activated
when the keyswitch is on and the emergency reverse switch is pressed. After the
emergency reverse switch is released, normal controller operation is not resumed
until neutral (no direction) is selected or until the interlock switch is cycled. The
recommended wiring is shown in Figures 3 and 4, pages 8 and 10. The controller
provides maximum braking torque as soon as the emergency reverse switch is
closed. The vehicle will then be automatically driven in the reverse direction at
the programmed emergency reverse current limit until the emergency reverse
switch is released.
CAUTION:
The polarity of the
F1
and
F2
connections will affect the
operation of the emergency reverse feature. The forward and reverse switches
and the
F1
and
F2
connections must be configured so that the vehicle drives away
from the operator when the emergency reverse button is pressed.
WIRING: Emergency Reverse Check
Al wire connected directly to the emergency reverse switch provides for broken
wire detection when that feature is programmed On (see Section 3
A
, page 42).
The emergency reverse check output wire periodically pulses the emergency
reverse circuit to check for continuity in the wiring. If there is no continuity, the
controller output is inhibited until the wiring fault is corrected.
The emergency reverse check wire is connected to J1 Pin 9 as shown in
Figures 3 and 4, pages 8 and 10. If the option is selected and the check wire is
