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.
1 — OVERVIEW
Like all Curtis PMC motor controllers, the 1297 offers superior operator
control of motor speed.
Features include:
✓
150–350 amp separately excited regenerative traction motor controller
✓
Field current standard at 25 amps on 150 and 250 amp controllers,
and at 35 amps on 350 amp controllers
✓
MultiMode™ feature allows two distinct user-selectable operation modes
✓
200–300 amp series pump motor controller, with choice of variable
PWM or ramped on/off
✓
Proportional lowering valve is controlled by a variable-current driver,
for precise control during lowering
✓
Lift and Lower operations start smoothly, because of hydraulic system
pre-load function
✓
Programmability through the Curtis PMC 13XX programmer
✓
Complete diagnostics through the 13XX programmer and through
the controller’s built-in Status LED
✓
Throttle inputs for single-ended or wigwag 5k
Ω
pots or 0–5V throttles
(both standard full stroke and restricted range); one throttle for the
traction system and one for the hydraulic system
✓
Active precharge of controller capacitor bank extends life of main
contactor tips
✓
Three hourmeters—total KSI-on hours, drive hours, pump hours—and
their associated maintenance timers are built into the controller, with
EEPROM storage (no battery)
✓
BDI calculations performed within controller
✓
Meets EEC fault detection requirements (standard M- PWM fault check)
✓
Fault detection circuitry on throttle inputs can be used to inhibit
operation if traction or hydraulic throttle signal goes out of range
for any reason
✓
Internal reverse polarity protection (no external diode required)
✓
Continuous diagnostics during operation, with microprocessor
power-on self-test
✓
All output drivers are short-circuit protected and provide built-in
coil spike protection
✓
Positive battery connections for all inputs
