engine ECM and not to the generator set control. For these engines the EMCP 3 must be programmed to receive the information for engine oil pressure and engine coolant temperature from the J1939 data link. If the EMCP 3 control is not programmed for data link input, the control will show diagnostics for the sensors. The spare analog input has a sensor map in the software for Engine Oil Temperature. The input can be programmed to monitor other parameters such as: Temperatures • Ambient Air Temperature • Exhaust Temperature • Right Exhaust Temperature • Left Exhaust Temperature • Rear Bearing Temperature Pressures • Air Filter Differential Pressure • Fire Extinguisher Pressure • Fuel Filter Differential Pressure • Oil Filter Differential Pressure • Starting Air Pressure Levels • Engine Coolant Level • Engine Oil Level • Fuel Level • External Tank Fuel Level However, there is only one sensor map in the software. If a parameter is desired other than Engine Oil Temperature, the factory must be contacted in order to create a custom flash file that contains the desired sensor map. All three inputs are designed to accept an input from a resistive sender with a range of 0 to 2000 ohms. If the resistance goes all the way down to zero, or above 2000 ohms, the control will give diagnostics for the sensors. In case of the spare analog input, the bounds are defined by the sensor map, and are limited to a minimum of 0 ohms and maximum of 2000 ohms. Each of the inputs also has configurable thresholds for high and low warnings and shutdowns. There are also programmable time delays for all of the events associated with the analog inputs. For information on how to program these thresholds and time delays, see “Setpoint Programming”.
3.10 Relay Outputs The EMCP 3.1 has six relay outputs. The EMCP 3.2 and 3.3 both have eight relay outputs. Each relay is capable of handling 2A @ 30 VDC. On EMCP 3.1 all six relays are type-A. On EMCP 3.2 and 3.3 six relays are type-A and two relays are type-C. Type-A relays are defined as one normally-open contact and a common. Type-C relays
