Use the following procedure to adjust the voltage and frequency of the generator output.
From the "MAIN MENU", use the down navigation key (15) or the up navigation key (12) to navigate to the "CONTROL" menu.
Press the "OK" key (14) to select the "CONTROL" menu. "VOLT/HZ CONTROL" will be displayed.Note: The voltage can be controlled from the EMCP 4 over CAN data link, discrete outputs, or analog outputs if a CDVR is installed on the generator. The speed can only be controlled if there is an ADEM on the engine.
Press the "OK" key (14).
Press the up navigation key (12) to increase the voltage and press the down navigation key (15) to decrease the voltage.Note: When adjusting the voltage using the navigation keys, an offset is applied to the set point value for "GENERATOR NOMINAL OUTPUT VOLTAGE". This set point is transmitted over the Primary CAN data link to the CDVR voltage regulator and is retained until battery power is cycled to the EMCP 4. Cycling the battery power to the EMCP 4 will remove the offset. Once the offset is removed, the transmitted value reverts to the set point value for "GENERATOR NOMINAL OUTPUT VOLTAGE".
Press the left navigation key (16) to decrease the engine speed. Press the right navigation key (13) to increase the engine speed.Note: When the left and right navigation keys are used to adjust the frequency, an offset is applied to the set point value for "GENERATOR NOMINAL OUTPUT FREQUENCY". This data is transmitted over the Primary CAN data link to the engine controller and is retained until battery power is cycled to the EMCP 4. Cycling the battery power to the EMCP 4 will remove the offset. Once the offset is removed, the transmitted value reverts to the set point value for "GENERATOR NOMINAL OUTPUT FREQUENCY".Note: Unlike the set points or preferences, for instance contrast, any changes to this screen takes effect immediately. The "OK" key and escape key will not save or cancel changes.Idle Speed and Rated Speed
The EMCP 4.1 and the EMCP 4.2 both can receive a discrete input from the customer, and also allow a selection on the screen or SCADA datalink for a customer to place the EMCP 4 into idle mode.Note: The "Engine Forced Idle Feature Enable Status" parameter must be set to "Enabled" within Cat ET prior to seeing this menu option on the display. This set point is under the "Automatic Start/Stop" submenu in Cat ET.If any signal is sending the generator set to Idle, the unit
