2 — INSTALLATION & WIRING: Throttle Wiring
to check for welded or missing contactor faults and uses the main contactor
coil driver output to remove power from the controller and motor in the event
of various other faults. If the main contactor coil is not wired to Pin 6 of
the 35-pin connector as shown, the controller will not be able to open the
main contactor in serious fault conditions and the system will therefore
not meet EEC safety requirements.
Note that the basic wiring diagram is designed for generic applications
and may not fully meet the requirements of your system. These controllers have
very flexible I/O and wiring configurations; you may wish to contact your local
Curtis representative to discuss your particular application.
SWITCH INPUT WIRING
The following inputs are dedicated to specific functions when the parameter
settings are as shown:
Switch 1: Emergency Reverse input if the EMR Enable = On
and EMR Type = 0 (see page 59).
Switch 3: Interlock input if Interlock Type = 0 (see page 48).
Switch 5: Lift input (depends on VCL program).
Switch 6: Lower input (depends on VCL program).
Switch 7: Forward input if Throttle Type = 1–3 (see page 42).
Switch 8: Reverse input if Throttle Type = 1–3 (see page 42).
THROTTLE WIRING
In this manual, the term throttle is used in two senses: as another name for the
drive throttle, and as a generic term covering both the drive throttle and the
brake throttle. Wiring is the same, whether the throttle in question is used for
braking or for acceleration.
Various throttles can be used with the 1234/36/38 controller. They
are characterized as one of five types in the programming menu of the 1311
programmer.
Type 1: 2-wire 5kΩ–0 potentiometers
Type 2: single-ended 0–5V throttles, current source throttles,
3-wire potentiometers, and electronic throttles
Type 3: 2-wire 0–5kΩ potentiometers
Type 4: wigwag 0–5V throttles and 3-wire potentiometers
Type 5: VCL input (VCL_Throttle or VCL_Brake)
The two throttle inputs (drive throttle and brake throttle) are programmed
independently.
