Low Coolant Level Sensor
Illustration 1 g00574577
The Low Coolant Level Sensor provides an indication of the coolant level to the operator. This indicator aids the operator in monitoring the proper coolant volume in the engine which prevents the engine from overheating. The operator can also receive an Engine Low Coolant Level Warning indication from the "PRCM" with the aid of this sensor.The signal of the Low Coolant Level Sensor is pulled to battery negative while the sensor is submerged in coolant. The signal stays at 5.0 DCV if the coolant level falls below the tip of the sensor probe. The Main Display Module converts the signal and the Main Display Module indicates the event by flashing the Low Coolant Level Indicator Lamp. The sensor is supplied with +8 DCV from the Main Display Module.Temperature Sensor For Marine Gear Oil

The Marine Gear Oil Temperature Sensor provides the operator with an indication of the oil temperature. The Marine Gear Oil Temperature Sensor aids in monitoring the proper marine gear oil temperature. The operator can receive a Marine Gear Oil Temperature High Warning indication from the Programmable Relay Control Module "PRCM" with the aid of this sensor.The sensor sends a pulse width modulated signal (PWM) with a duty cycle that varies as the Marine Gear Oil Temperature changes from the sensor to the Main Display Module. The sensor frequency is 4.2 kHz. The Main Display Module displays the value of the PWM signal on the Premium Quad Gauge Electronic Module.Low Fuel Level Switch
Illustration 3 g00574581
The Low Fuel Level switch provides an indication of a low fuel level to the operator. The Low Fuel Level switch aids the operator in preventing an unexpected shutdown because of an empty fuel supply tank. The operator can also receive an Engine Low Fuel Level Warning from the "PRCM" with the aid of the Low Fuel Level switch.The Low Fuel Level Switch is closed while the switch is submerged in fuel. The switch is open if the fuel level falls below the tip of the switch. The Main Display Module converts the signal. The Main Display Module indicates the event by flashing the Low Fuel Level Warning Lamp.
