The particle detector warns the engine when metal particles are detected in the lubricating oil. The particle shuts down the engine when metal particles are detected in the engine oil. The sensor consists of a grid that has parallel copper traces on a circuit board. Alternate traces are connected to +24 VDC and to the I:2.0/1 input of the PLC. When an electrically conductive particle bridges the gap between the parallel traces, current flows. The I:2.0/1 input of the PLC becomes active. This triggers an alarm. If the condition exists after a time delay, the engine will shut down.Jacket Water Detector Switch
The switch is an electronic sensor that detects the presence of coolant. If coolant is present, the output of the switch is OFF. If coolant is not present, the relay "JWDAR" is energized. An alarm is generated.Start Oil Switch
The start oil switch is used in order to determine if the engine is lubricated prior to starting. The control panel supports both the intermittent prelube system and the continuous prelube system. A pressure switch is used with intermittent prelube systems. A detector is used with continuous prelube systems.Liquid Detector Gp

The switch is an electronic sensor that detects the presence of oil. If oil is present, the output of the switch is ON. When there is a presence of engine oil and a presence of generator oil pressure the "SOSR" relay is energized. The "Starting Oil Pressure Lamp" turns on and the engine is allowed to start.Pressure Sender
Illustration 3 g00763715
The pressure sender varies resistance with pressure. The variable resistance is used in order to drive the "Air Start Gauge".Oil Level Switch
The switch provides an alarm signal if the oil level is too low in the oil pan. The switch is wired in the normally open position. A normal water level in the expansion tank holds the contacts of the switch closed. If the oil level falls and the contacts break, the I:2.0/0 input of the PLC becomes inactive. An alarm is then generated.Speed Sensor for the Turbocharger
The turbocharger speed sensor is used in order to measure the rotational speed of the turbocharger in RPM. The speed is monitored and an alarm is generated when the speed of the turbocharger exceeds 35000 RPM.

The turbocharger has a speed sensor that is installed. The PLC will convert the pulse that is generated by the blade pass into the RPM for the turbocharger.Speed Sensor with 90° Inlet
Illustration 5 g00763728
This sensor is optional. The sensor detects the speed of the turbocharger from a slot on a bolt that is mounted on the turbocharger.Rotary Sensor
Illustration 6 g00763722
The sensor is tied to the fuel control housing through a linkage. Movement of the fuel control linkage is converted into an electrical signal. The signal is amplified to a 4-20 mA signal that is proportional to the position of the rack of the engine. Refer to Special Instruction, REHS0923 for information on calibration and adjustment.
