- Voltage mode: 0-5 V with software-selectable sub ranges. The input impedance is a minimum of 10k ohms, and a maximum of 1M ohms. The analog input return signals must be tied to battery negative external to the controller.
- Resistive Sender (VDO type motor) Mode: 5-2000 Ohms with software-selectable nonlinear maps. Accuracy is 1% or 0.5 ohms accuracy, whichever is worse. The analog input return signals must be tied to battery negative external to the controller.
The analog inputs have a 5 VDC common non-isolated power supply capable of supplying up to 100 mA of current, with overload protection. This supply is to be used to provide power to sensors if required by the source power pin and analog input returns. The negative side of this supply is battery negative.
Analog inputs programmed to monitor pressures should be wired to sensors that read gauge, not absolute pressure, unless absolute pressure is desired.
For analog inputs, the data range can be positive or negative, but event thresholds are only positive. Therefore, to prevent nuisance alarms for low warnings, disable the "Event Response Configuration" if data is acceptable to be negative.
The first and second analog inputs are configured by default for non-electronic engines. The inputs are to monitor engine oil pressure and engine coolant temperature, respectively, and are protected by level 3 security. The third analog input by default is protected at level 2 security.
Alternately, Cat ET can be used to program these set points.
Note: If the analog inputs are set to "DISABLED", then any sensor faults or events will not be broadcast or annunciated on the network.
Note: If more than one analog input is configured for the same physical quantity (that is, the set point "Analog Input Data Identification" matches between two "Analog Inputs"), then the higher numbered "Analog Input" value will be displayed on the "Engine Overview" screen. The following is an example. If both "Analog Input #2" and "Analog Input #3" are configured for oil temperature, but the sensor is connected only to "Analog Input #2" (and "Analog Input #3" is left open), a display of "****" diagnostic will result. The "Engine Overview" screen will display the value from "Analog Input #3". Warnings and shutdowns will be monitored for both analog inputs. When troubleshooting inputs, always make sure to check for configuration conflicts.
The analog inputs are not used for electronic engines that use ADEM A3, A4, or newer, engine ECM. On the electronic engines, the engine oil pressure sensor and the engine coolant temperature sensors are wired to the engine ECM. On the electronic engines, the engine oil pressure sensor and the engine coolant temperature sensors are not wired to the generator set control.
Inorder to receive the sensor information from the data link instead of from sensors wired into the EMCP 4, the set points "Engine Oil Pressure Sensor Configuration" and "Engine Coolant Temperature Sensor Configuration" must be set to "Data Link". If the set points are not set correctly, the sensor values on the "Engine Overview" screen on the EMCP 4 display will show "****".
Note: Improper configuration of the inputs can cause a false event to be triggered or cause an event not to trigger when desired. If a user disables an input without including other external protection, or disables the annunciation of an enabled input, detection will not be available. If a spare input is enabled, but not wired to a sensor, a false event may occur.
The programming of the analog inputs starts by selecting a "Usage Type". The rest of the programming is dependent upon what "Usage Type" is selected. Illustration 1 summarizes the paths possible for programming an analog input.

| (1) | Useful for temperatures based on CAT sensor. The EMCP only supports down to 10 degrees Centigrade). |
The EMCP 4.1 and EMCP 4.2 voltage senders can be configured within the ranges in Table 15.
| Analog Input Ranges | |
| Voltage Sender Ranges | 0V to 5V |
| 1V to 5V | |
| 0.5V to 4.5V | |
Analog input data ranges can be defined with positive and negative values. Event thresholds are only programmable as positive values. To prevent nuisance alarms for low warnings when using negative numbers for data ranges, the "Event Response Configuration" can be disabled. The input data must be acceptable to be negative.
Each of the inputs can be configured to have "HIGH WARNINGS", "LOW WARNINGS", "HIGH SHUTDOWNS"and "LOW SHUTDOWNS". The inputs have thresholds that can be configured. Any value below the bottom point on the map or above the highest point on the map will raise a corresponding diagnostic event. Also, all of the events associated with the analog inputs have programmable time delays. "Low Idle Oil Pressure" set points are also available under the "Engine Oil Monitor" menu.
Unsupported Analog Input Sensor Ranges
There may be voltage sensors available that use ranges not explicitly supported by the EMCP 4. Depending on the situation, there may be different ways to handle the unsupported sensor ranges. The following sections give options on how to handle the situations.
Sensor Range is Smaller than Set Point Options
If the desired sensor range is smaller than one of the available set point options, then extrapolation may be used to support the desired sensor. For example, for a 0 to 3 VDC temperature sensor reads
| |
| Illustration 65 | g02274673 |
|
Mathematical Extrapolation of Maximum Data Range | |
The maximum data range can be found graphically or algebraically. In the example, the maximum data range would be defined by the equation of the line after the slope is determined. Since the data rises by 50 degrees for every volt, increasing 2 V above the 3 V limit requires the maximum range to be 100 degrees above the sensor limit of 120 degrees. The total would be 220 degrees. Refer to Illustration 66.

Sensor Range is Larger than Set Point Options, but Usable Range is not
If the desired sensor range is larger than one of the available set point options, but the useful range for the sensor is within the supported ranges, then interpolation may be used to support the desired sensor. For example, for a 0 to 6 VDC temperature sensor that reads

Mathematical Interpolation of Maximum Data Range | |
The maximum data range can be found graphically or algebraically. In this example, the maximum data range would be defined by the equation of the line after the slope is determined. Since the data rises by 90 degrees for every volt, decreasing 1 V below the 6 V limit requires the maximum range to be 90 degrees below the sensor limit of 500 degrees. The total will be 410 degrees. Refer to Illustration 68.

Sensor Range is Larger than Set Point Options, and Usable Range is Larger than Set Point Options
If the desired sensor range is larger than one of the available set point options, and the useful range for the sensor is outside of the supported ranges, a third-party device is required to convert the signal range into a supported range. Refer to Illustration 69.
