(1) Coolant Level Switch
(2) Coolant Pressure Sender (Alarm)
(3) High Coolant Temperature Switch (Shutdown)
(4) High Coolant Temperature Transmitter (Alarm) Coolant Level Switch 1
The coolant level switch is powered from the panel. An alarm can be activated by a signal from the coolant level switch. There are two different types of coolant level switch. One switch is designed to be used on an expansion tank. The other switch is design in order to be used on a radiator.Coolant Pressure Sender 2
The coolant pressure sender is powered from the panel. If an incorrect signal is received, an alarm will be activated by the control panel when a signal is received from the coolant pressure sender.High Coolant Temperature Switch (Shutdown) 3
A signal will be sent to the panel if high coolant temperature occurs.High Coolant Temperature Transmitter 4
The coolant temperature transmitter is powered from the panel. The transmitter can shut down the engine.Fuel Pressure Switch 5
The fuel pressure switch is powered by the panel.

(5) Fuel Pressure Switch
(6) Primary Fuel Differential Pressure Switch (Alarm)
(7) Secondary Fuel Differential Pressure Switch (Alarm)
(8) Water Separator Switch (Alarm) Primary Fuel Differential Pressure Switch 6
The inlet pressure and the outlet pressure of the primary fuel filter is monitored.Secondary Fuel Differential Pressure Switch 7
The inlet pressure and the outlet pressure of the secondary fuel filter is monitored.Water Separator Switch 8
The switch will operate if water is present in the bottom of the filter.Alarm Tank Switch 9
If the high pressure fuel line should rupture the tank will fill with fuel and the switch will be operated.Note: This switch can be installed on an engine that is equipped with the EMCP3 control panel.

(9) Alarm Tank Switch
(10) Oil Pressure Shutdown switch
(11) Oil Pressure Transmitter (Alarm)
(12) Oil Filter Differential Pressure Switch (Alarm)
(13) Oil Temperature Sender (Alarm) Oil Pressure Switch 10 Shutdown
The oil pressure switch can send a signal to the control panel in order to shut down the engine.Oil Pressure Transmitter 11
The oil pressure transmitter is powered from the panel. If an incorrect signal is received, an alarm will be activated by the control panel when a signal is received from the oil pressure transmitter.Oil Filter Differential Pressure Switch12
The inlet pressure and the outlet pressure of the oil filter is monitored.Oil Temperature Sender 13
The sender will signal the panel if high oil temperature occurs.Note: The magnetic pickup is used in order to shut down the engine if an overspeed condition occurs.
