Littelfuse M2000.0120 - Engine Controller 120. The M2000 Engine Controller will control and protect any industrial combustion engine, which accepts discreet I/O signals for control of the crank, the fuel valve and the stop solonoid (if applicable). The engine must be able to supply potential free contacts for starter disengagement and over speed alarm (normally done through a standard tacho relay). The M2000 is typically used as an engine controller for diesel or gas driven generator sets. The operator can start the engine either by pressing a button on the front facia, or by providing and external start signal through a potential free contact (e.g. a relay). The M2000 can be configured to perform multiple start attempts. The M2000 detects a successful start from the crank disconnect signal provided by the tacho relay (normally at 33percent of nominal speed). The M2000 will operate the fuel valve as well as a start warning signal shortly before cranking the engine. The progress of the start sequence is clearly indicated on the front facia LEDs.

Littelfuse D0920.0060 - The D0920 Arc Detection Unit is a high-speed arc-detection device for electrical power-distribution systems. The D0920 supports up to three point sensors (A0220) mounted in a switchboard, and requires a 230 Vac supply. On the occurrence of an arc fault, the D0920 detects the fault and pulses the trip output in less than 1 ms. The fast trip time reduces the risk of personal injury and equipment damage. The D0920 is typically supplied from the switchboard main power. The AC voltage may fail when an arc fault develops. The D0920 uses energy stored in an internal capacitor to trip the circuit breaker. The storage capacitor is an extremely long-life electrolytic capacitor with a specified life time of more than 30 years at an ambient temperature of 50°C (121°F). The trip energy stored is sufficient for circuit breakers with a 220/250 Vdc shunt trip coil. The D0920 has one output indication relay with an isolated normally-open contact, and one output indication relay with an isolated normally-closed contact. Additional features include power and trip indication, test mode, and sensitivity adjustment.
