C13 and C15 Generator Sets Single Unit Operation Caterpillar

Initial Start-Up

Measure the insulation resistance of each winding if the generator was exposed to the following conditions:

• Rapid changes in temperature

• Freezing

• Wet climate during shipment

• Wet climate during storage

Refer to this Operation and Maintenance Manual, "Insulation - Test".

Note: These tests should be conducted prior to any power connections or control connections that are being made.

Starting

1. Make all preliminary engine starting checks.

2. Be sure that the main circuit breaker or the line circuit breaker is open.

3. Start the engine. Allow the engine to warm up.

4. Adjust to the full load engine speed.

5. Close the main circuit breaker.

6. Apply the load. Do not try to apply the full load. Apply the load in increments in order to maintain system frequency at a constant level.

7. Readjust the governor for rated frequency.

Adjust the Voltage

Use the following procedure in order to adjust the voltage and frequency of the generator output.

1. From the "MAIN MENU", use the down navigation key (15) or the up navigation key (12) in order to navigate to the "CONTROL" menu.

   1. Press the "OK" key (14) in order 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. The speed can only be controlled if there is an ADEM on the engine.

   2. Press the "OK" key (14).

   3. Press the up navigation key (12) in order to increase the voltage and press the down navigation key (15) in order 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 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".

   4. Press the left navigation key (16) in order to decrease the engine speed. Press the right navigation key (13) in order 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 setpoints 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.

Stopping

1. Remove the load in increments.

2. Open the circuit breaker.

3. Press "STOP" on the EMCP.

4. Allow the engine to run for at least 3 minutes in order to cool. The EMCP will shut down the engine after cool down time has been reached.
