Symptoms & remedies

Symptom	Cause	Remedy
PRE-HI ENGINE TEMP LED. Engine continues to operate		1. Indicates engine has begun to overheat and engine temperature has risen approximately 215°F (105°C). If generator is powering non-critical and critical loads and cannot be shut down. a. Reduce load if possible by turning off non-critical loads. b. Check air inlets and outlets and remove any obstructions to airflow. c. Open doors or windows in generator area to increase ventilation. 2. If engine can be stopped, follow procedure i in Step 2.
HI ENGINE TEMP LED. Engine shuts down		1. Indicates engine has overheated (engine temperature has risen above 225°F/110°C) or coolant level is low (sets with coolant level sensor). Allow engine to cool down completely before proceeding with the following: a. Check coolant level and replenish if low. Look for possible coolant leakage points and repair if necessary. b. Check for obstructions to cooling airflow and correct as necessary. c. Check for a slipping fan belt and tighten if loose. d. Reset control and restart after locating and correcting problem. Contact your Dealer or Distributor if none of the above.
PRE LOW OIL PRESSURE LED. Engine continues to operate		3. Indicates engine oil pressure has dropped to 20 psi (138kPa). If generator is powering critical loads and cannot be shut down, wait until next shutdown period and then follow Step 4 procedure. If engine can be stopped, follow procedures in Step 4.
LOW OIL PRESSURE LED. Engine shuts down		4. Indicates engine oil pressure has dropped to 15 psi (97kPa). Check oil level, lines and filters. If the oil system is okay, but oil level is low, replenish. Reset control and restart. Contact your Dealer or Distributor if oil pressure is not in the range of 35 to 55 psi (21 to 379 kPa).
OVERCRANK LED. Engine stops cranking		A. Check for empty fuel tank, fuel leaks, or plugged fuel lines and correct as required. b. Check for dirty fuel filter and replace if necessary (See Maintenance section of Engine Manual). c. Check for dirty or plugged air filter and replace if necessary (See Maintenance section of Engine Manual). d. Refer to Step 4. e. Reset the control and restart after correcting the problem. Contact your Dealer or Distributor for service if none of the above.
Engine runs and then shuts down, OVERSPEED LED		Indicates engine has exceeded normal operating speed. Refer to governor adjust procedure. Contact your Dealer or Distributor for service.
UNIT NOT IN AUTO LED		7. Indicates AUTO/OFF/MANUAL switch is in the OFF position which will prevent automatic starting if an automatic transfer switch is used. Move the AUTO/OFF/MANUAL switch to the AUTO position for automatic starting.
LOW FUEL LED. Engine continues to run		8. Indicates diesel fuel supply is running low. Check fuel supply and replenish as required.
LOW FUEL LED. Engine shuts down and LOW OIL PRESSURE LED		9. Indicates engine has run out of fuel. Check fuel level and replenish as required. See Engine Manual for fuel system priming procedure.

Procedures

ADC-RES Controller Configuration (Cn setting) adjustment

⚠ The controller automatically exits configuration mode without saving changes after about 1 minute if no buttons are pressed.

Enter the configuration mode while the engine is not running by following the Figure 26 sequence.
Step through the parameters to the communication setting Cn parameter.
Use the up and down arrow buttons to change the Cn setting to Cn01, if necessary.
Press to SAVE CHANGES (YES) before exiting the configuration mode.
Move the generator set master switch to OFF/RESET.

Adjusting V-Belt Tension adjustment

⚠ Over tightening may cause overload on the bearings and pulleys of the drive belt components.

⚠ The engine manufacturer does not recommend the use of 'belt dressing' or 'anti slipping agents' on either belt configuration.

Check belt tension by pressing down on the midway point of the longest stretch between two pulleys.
The belt should not depress beyond 13mm (1/2 inch).
If depression is more than allowable, adjust the tension.
Do not over tighten the belt tension.

Controller Configuration adjustment

⚠ Be sure to save the new settings immediately before exiting the configuration mode; changes are lost if the controller times out (about 1 minute).

Hold the Select button and move the master switch to RUN to enter configuration mode.
Press the down arrow key then the up arrow key 3 times to enter configuration mode (password).
Set the voltage/frequency parameter Uu for the model.
Set the unit configuration parameter Uc (marine, standby, mobile).
Set the engine type parameter Ec.
Press the up arrow at the Adnc display to enter advanced configuration mode.
Set the engine data input type Ed.
Set the battery voltage Bt (12 or 24 VDC).
Set the communications parameter Cn.
Enter save mode and save your settings before exiting.

Output Voltage and Frequency Adjustment adjustment

⚠ The generator set must be running during these adjustments.

⚠ The engine speed (frequency) adjustment menus are not accessible on models with mechanical governors.

Tools: multimeter

Move the master switch to RUN; the engine starts and runtime hours display.
Hold the Select button about 5 seconds until the program version number displays.
Press the down arrow key then the up arrow key 3 times to enter adjustment mode.
1P: adjust voltage coarse in large increments (approximately 5-7 volts per step).
2P: adjust voltage fine in smaller increments (approximately 0.5-0.7 volts per step).
Adjust voltage stability (gain) coarse and fine.
3P: set volts/Hz (00=low, 09=high).
4P: adjust engine governor speed coarse and fine.
5P: adjust engine governor stability (gain) coarse and fine.
Enter SAVE mode and save settings before exiting the adjustment mode.

Network Bridge Diagnostics diagnostic

Check the network LEDs on the RJ45 connector for Ethernet network communication.
Check the STAT LED; if not lit, check connections and the engine starting battery.
Check the TX and RX LEDs for CAN data transmission and reception.
If neither the TX nor the RX LED flashes, check bridge power, connections, and settings.
If only one of the TX or RX LEDs flashes, check the connected devices on the generator set (CAN) side.
