Page 7: Product Overview
Engine Protection System, part number 3565 ® The Muirhead Engine Protection system (EPS), part number 3565, is designed to monitor almost any alarm ® condition on virtually any machine. This system has been designed to monitor six inputs including an AC input for detecting coolant loss and three digital outputs. -
Page 8: Operation And Use
Operation and Use Control Unit Electronic circuitry within the EPS control unit checks the state of the switches and sensors, and then activates the corresponding alert indicator and control outputs when an alarm condition is sensed. The EPS label displays the alert indicator or function that has faulted. A test switch on the front of the EPS control unit allows the operator to simulate a fault and test the complete system. -
Page 9: Inputs
Inputs The following input functions show the factory defaults with all inputs and outputs being configurable. Refer to document number P0021 for advanced programming information. Contact your local RCT branch or distributor for a copy of the document or for more information. Function 1 This input is configured to have a five-second delay prior to pulsing the alert indicator and activating the alarm. -
Page 10: Outputs
Outputs Alarm Control Output This circuit is activated as soon as an alert indicator is active. This output remains active until the EPS control unit has no alert indicator active or the key is switched off. This output is disabled until a start signal is sensed. This allows servicing to be carried out with the key on without the alarm sounding. -

Page 13: Coolant Temperature Switch - Function 3
Coolant Temperature Switch – Function 3 The coolant temperature switch should be installed on the engine side of the thermostat control. It is imperative that the switch sensing area (bulb) be immersed in coolant. Install the switch using thread sealant. Note Care should be taken when selecting a mounting port to allow sufficient depth for the bulb. -
