Detector (Jacket Water)
Illustration 1 g00792220
Detector for the jacket waterThe detector detects the presence of engine coolant.The detector is an electronic sensor with a set of normally closed contacts.When coolant is present, the output will be off. When coolant is not present, the output will energize the relay ("JWDSR"). For "minimum" systems, the alarm system will be activated. For "complete" systems and "maximum" systems, the shut down circuit will be activated.Detector (Starting Oil)
Illustration 2 g00792247
Detector for the engine oil for startingThe detector detects the presence of engine oil for starting.The detector is an electronic sensor with a set of normally open contacts.When oil is not present, the output will be off. When oil is present, the output will energize the relay ("SOR"). The relay will then illuminate the "STARTING OIL PRESSURE" lamp and the relay will also enable the starting circuit for the engine.Particle Detector
Illustration 3 g00792258
Particle detector for the engine oilThe particle detector detects the presence of metal particles in the engine oil.The detector is an electrical sensor. The sensor is a circuit board which consists of a grid of copper traces.When metal particles close the gap between the copper traces, the circuit closes and the alarm circuit is activated. The circuit also energizes the timer ("PDSTD") and the shutdown circuit is activated after a set period of time.
