Features Include:
60-200 amp AC induction motor controller
MultiModeâ„¢ feature allows two distinct user-selectable operation modes
Easily programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station
Complete diagnostics through the programming devices and through the controller's built-in Status LED
Throttle input for single-ended or wigwag 5kΩ pots or 0-5V throttles (both standard full stroke and restricted range)
Active precharge of controller capacitor bank extends life of main contactor tips
Two hourmeters - total KSI-on hours and drive 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
Fault detection circuitry on throttle inputs can be used to inhibit operation if throttle signal goes out of range for any reason (applies both to the traction throttle and, in applications that include a proportional valve, to the hydraulic throttle as well)
Stall protection
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
Fully protected inputs
Internal and external watchdog circuits ensure proper software operation
High environmental protection rating (IP53)
3-wire serial interface for multifunction display
