M2100 Emergency Controller
■The SELCO M2100 Emergency Controller has been designed to take care of the complete control of an emergency generator. It controls start and stop of the engine, monitors the engine and the transfer during start and operation, and simultaneously indicates - on the front - all necessary information about the conditions of the emergency generator. In case of loss of normal supply the unit will be activated via an external voltage relay. If activated during the entire start delay period (2-4-10-15 sec.) the start will be initiated. It is possible to select up to 4 start attempts, with both crank and rest periods adjustable (5-7-10-15 sec.).
■When the engine has started, a signal from an internal or external tacho relay (crank disconnect) detects in excess of 33% of the nominal frequency, and the cranking will be disconnected. When the generator voltage has reached 90%, the unit activates, and after engine warm-up period (0.5-2-4-10 sec.) has expired the normal supply is disconnected and 0.5 sec. later the emergency supply is connected.
■When the normal supply returns, and is maintained in the entire “return-to-normal” period (1-2-4-10 min.) the emergency supply is disconnected and 0.5 sec. later the normal supply is connected.
■The engine runs unloaded in the cool- off period (0-3-10-30 min.) before shut down.
■Besides above main functions the controller contains many other features.
●Automatic Mains Failure unit - provides complete control of an emergency diesel generator set.
■Easy control of load transfer between normal supply and emergency generator.
■10 LED’s on front panel indicates all necessary information about the conditions of the emergency generator.
■16 inputs for start/stop, crank disconnect, low oil pressure, alarms and other parameters.
■11 outputs for connection to external relays and other control equipment.
■Easy programmable. E.g. start attempts, time sequences, external circuit check etc. programmable via switches.
■Automatic test and intermittent pre-lubrication.
■Clear indication if all conditions for emergency supply are present
■Internal siren output relay
■Compact unit for easy front panel mounting.
