EMCP 4.1/4.2 Advanced Feature Summary This document will provide a high level summary of some of the advanced features found in the EMCP 4.1 & 4.2 controllers. This is not intended to be a complete list of features nor replace the A&I guide and service manuals, but rather to serve as a quick reference to certain features and functions that could be overlooked. Security Like the EMCP 3, EMCP 4 includes multiple security levels that can be set in the field to prevent un-authorized access operate the generator set. The EMCP 4 is equipped with five security levels: Level 0 (accessible by anyone), level 1 & 2 (password at controller), level 3 (factory password), and service tool, which required Cat ET to change. See Section 6: Security in the A&I guide for more information. Physical Run/Auto/Stop Switch In some installations, it is required that there be a physical switch, often a key switch, to place the generator set controller into a specific mode of operation, such as AUTO. The digital inputs on the EMCP 4.1 or 4.2 controllers can be configured to accept a switched input See Section 8: Digital Inputs in the A&I guide for more information. Analog Inputs The EMCP 4.1 and 4.2 support three analog inputs. For mechanical engines, the first two analog sensors are factory programmed for monitoring oil pressure and water temperature. For electronic engines with the ADEM controller, all three are available for customer use. The inputs can be programmed for either a 0-5 volt sensor or a 5-2000 ohm resistive sender and can monitor a wide range of parameters, such as oil temperature, fuel level, urea level, or customer defined parameter. See Section 9: Analog Inputs in the A&I guide for more information. Outputs The EMCP 4.1/4.2 support relay outputs capable of 2A at 30 VDC. The EMCP 4.2 also supports two programmable discrete sinking outputs. These outputs can be configured for a number of conditions, including generator set mode of operation (run/auto/stop), not in auto, crank alert, engine started, common warning, common shutdown and programmable kW relay trip (EMCP 4.2 only). See

Section 10: Outputs in the A&I guide for more information. Modifiable text strings Modifiable text strings give the customer the ability to customize an event name of a custom event. For example, if the building fire detection system were wired into the genset, a custom event called Building Fire Detected could be programmed into the EMCP controller, and would appear on the display and be recorded in the event log. See Section 11: Modifiable Text Strings in the A&I guide for more information. Programmable Cycle Timer (EMCP 4.2 only) The programmable cycle timer allows the operator to program up to seven independent times in a week when a generator set will run. When activated, the generator will start and run for the pre-programmed time. See Section 13: Programmable Cycle Timer in the A&I guide for more information. Reduced Power Mode Like EMCP 3, EMCP 4 is equipped with a reduced power mode feature that puts the EMCP controller into a state where the power consumption is reduced. This will extend the amount of time the generator set can sit between runs before the controller drains the batteries. See Section 14: Reduced Power Mode in the A&I guide for more information. Programmable kW Relay (EMCP 4.2 only) The EMCP 4.2 controller has two programmable kW relay functions that can be programmed to activate when the generator set kW exceed a customer defined threshold, and activate an available EMCP 4.2 output. See Section 15: Programmable kW Relay in the A&I guide for more information.
