DESCRIPTION
The Model 511 is a Manual Engine Control Module which has been designed to allow the OEM to meet demand for increased capability within the industry. The module is used to start and stop the engine, indicating the operational status and fault conditions; automatically shutting down the engine and indicating the engine failure by means of a flashing LED. Any simultaneous faults are indicated by a steady LED. Selected operational sequences, timers and alarms can be altered by the customer. Alterations to the system are carried out using a PC and the 808 interface. This also provides the operator with real time diagnostic facilities to monitor the operation of the system. Operation of the module is via a two position key switch mounted on the front panel with STOP and RUN positions. A START pushbutton is fitted to facilitate engine cranking. Microprocessor control allows enhanced manual start operation, Crank inhibit if the engine is running, automatic crank disconnect and also a crank limit timer to prevent starter motor damage in the event of a fail to start occurring.
DESCRIPTION (Continued) Relay outputs are provided for Fuel Solenoid Output, Start Output and two configurable outputs. The relays are factory configured as pre-heat and alarm output, however the relay function is configurable to activate on a range of functions, conditions or alarms. The relays supply positive plant supply out. Configurable inputs are available for Low Oil Pressure, High Engine Temperature and Remote Fuel On. This allows the module to function with N/O or N/C switches. Two fully configurable auxiliary inputs are provided to give protection expansion. These can be selected to be indication, warning or shutdown inputs either immediate or held off during start up. Uncommitted LEDS allow for annunciation. Multiple alarm channels are provided to monitor the following:- Overspeed, Charge Fail, Emergency Stop, Low oil pressure, High engine temperature, and programmable inputs as selected. First up alarm is indicated by a flashing LED. Subsequent alarms are displayed by a steady LED. The Remote Fuel On facility is intended for use where a dual engine start position is required. The module will turn on the fuel supply and provide all normal protections to the engine. However engine cranking must be performed externally to the module via a key switch or push-button connected in parallel with the module crank relay. The 500 series modules have been designed for front panel mounting. The module is fitted into the cut-out with the fixing clips removed. These are then fitted from the rear. Connection is via locking plug and socket connectors.
