ated 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
