Fault codes

Code	Name	Meaning	Severity	Action
101	IDLE MODE	Indicates that the engine is operating in idle mode. Grounding the engine idle input inhibits generator build-up and governs the engine at 800 RPM; control lowers oil pressure warning and shutdown trip points accordingly.

Procedures

Convert Day Tank Controller 240 VAC to 120 VAC adjustment

Remove the two jumpers between terminals TB1-6 and TB1-7.
Connect one jumper between TB1-5 and TB1-6 and the other between TB1-7 and TB1-8.
Move selector switch S103 on the control PCB to the up position for 120V.
If equipped with a transformer, remove jumpers between H2 and H3 and connect one between H1 and H3 and the other between H2 and H4.

Day Tank Controller Conversion 240 VAC to 120 VAC adjustment

Remove the two jumpers between terminals TB1-6 and TB1-7 and connect one between TB1-5 and TB1-6 and the other between TB1-7 and TB1-8.
Move selector switch S103 on the control PCB to the up position for 120V.
On the control transformer, remove the two jumpers between terminals H2 and H3 and connect one between H1 and H3 and the other between H2 and H4.

Dip Adjustment adjustment

Turn the DIP pot clockwise to increase the voltage vs frequency slope for frequencies below the UFRO threshold.
Greater slope gives greater voltage roll off as frequency drops, easing large load pickup but increasing voltage dip.
Turn the pot fully counterclockwise to make the slope the same above and below the threshold frequency.

Dwell Adjustment adjustment

Turn the DWELL pot clockwise to increase dwell time (voltage recovery time when frequency dips below threshold).
Turn the DWELL pot fully counterclockwise to eliminate dwell.
With no dwell, voltage recovery follows engine speed recovery.

Governor Adjustments (Type A Electric Governor) adjustment

Set selector switch S1 to OFF, S2 to appropriate model position.
Set pots initially: Gain 20%, I 20%, D 30%, Droop 0%.
Start set, adjust Speed pot for required frequency (60Hz=1800RPM or 50Hz=1500RPM) at operating temperature.
Disconnect load, turn Gain pot to 100% or until unstable, then back off until stable.
Adjust D and I pots similarly; readjust Speed if necessary.
Push throttle to minimum speed, release and observe overshoot (2-5 Hz acceptable); adjust I pot to reduce overshoot or hunting.

Initial Start Setup adjustment

⚠ Selecting this menu resets all operating parameters to default values; perform only by technically qualified personnel.

Press RESET, MENU and PHASE SELECT simultaneously to invoke the Initial Start Setup menu.
Toggle the Standby/Prime option.
Select the correct generator set model, frequency and kW rating.
Select the correct nominal line-to-line output voltage.
Select DELTA or WYE.
Select SAVE to save changes; MAIN MENU is then displayed.

Operating PowerCommand in Droop Mode adjustment

Set the no load speed and voltage at the desired level (bus must be de-energized or disconnect Bus PT module).
Apply 100% load and adjust KW load sharing gain for desired full load frequency; adjust KVAR load sharing gain for desired full load voltage.
Repeat the process for other generator sets in the system.
Test the system with all available load and verify approximately equal load sharing at no load and maximum load.

Over / Under Voltage Module Recalibration adjustment

Remove the two screws securing the top to the case and withdraw the top assembly.
Adjust the UNDER setpoint SET pot to 75 percent.
Apply single-phase, 60 Hertz, 104.25 VAC across terminals L and N.
Adjust pot R25 on the PC board until the relay trips (de-energizes).
Adjust the OVER setpoint SET pot to 125 percent.
Apply single-phase, 60 Hertz, 173.75 VAC across terminals L and N.
Adjust pot R26 on the PC board until the relay trips (energizes).
Repeat until no adjustments are necessary, then reassemble the module.

Torque Tester / Current Transformer Installation Check adjustment

Verify the dot on the CT faces toward the generator.
Verify CT21 is on U load leads, CT22 on V load leads, CT23 on W load leads.
Verify the correct CT secondary terminal (pin 2 high voltage / pin 3 low voltage) is used.
Check CT/PT wiring if a 335 Reverse Power shutdown occurs.

UFRO (Under Frequency Roll Off) Adjustment adjustment

⚠ High voltage - use insulating protection

Note the red LED on the board lights when frequency dips below threshold.
Turn the UFRO pot clockwise to raise the threshold frequency.
Turn the UFRO pot counterclockwise to lower the threshold frequency.
Determine threshold frequency by lowering generator frequency until the LED lights.

Voltage and Voltage Stability Adjustments (AVR) adjustment

⚠ High voltage - use dry wooden platform or rubber insulating mat, dry clothing, no jewelry, elbow length insulating gloves

Measure generator output voltage while running without load at nominal frequency.
Lock the control panel voltage trimmer at its midpoint if it cannot provide enough adjustment.
Turn the VOLTS pot fully counterclockwise and the STABILITY pot to its midpoint.
If the red LED lights, refer to Jumper Reconnections and UFRO Adjustments.
Turn the VOLTS pot clockwise until rated voltage is obtained.
If voltage becomes unstable under large load, turn the STABILITY pot clockwise until stable.
Check and readjust the VOLTS pot each time the STABILITY pot is readjusted.

Servicing the PMG diagnostic

⚠ Touching uninsulated high voltage parts can result in severe personal injury or death.

Tools: Wheatstone bridge, digital ohmmeter

Disconnect leads P2, P3, P4 from voltage regulator.
Start engine and let speed stabilize.
Measure voltage across lead pairs P2-P3, P3-P4, P4-P2; should be at least 150 VAC (50Hz) or 180 VAC (60Hz).
Stop set and measure resistance across same lead pairs; each winding approximately 4.4 ohms.
Torque PMG rotor center bolt to 40 ft-lbs (54 Nm) when reassembling; stator leads must be at 12 o'clock.

Troubleshooting

Symptoms & remedies

Symptom	Cause	Remedy
Green RUN lamp lights following engine startup		Indicates all engine systems are normal. No corrective action required.
PRE HI ENGINE TEMP lamp lights. Engine continues to operate	Engine has begun to overheat and engine temperature has risen to approximately 215°F (102°C)	If generator is powering non-critical and critical loads and cannot be shut down: reduce load if possible by turning off non-critical loads; check air inlets and outlets and remove any obstructions to airflow. If engine can be stopped, follow procedure in step 3.
HI ENG TEMP lamp lights. Engine shuts down	Engine has overheated (engine temperature has risen above 222°F/106°C) or coolant level is low (sets with coolant level sensor)	Allow engine to cool down completely before proceeding: check coolant level and replenish if low, look for possible coolant leakage points and repair if necessary; check for obstructions to cooling airflow and correct as necessary; check for a slipping fan belt and tighten if loose; reset control and restart after locating and correcting problem; contact an authorized service center for service if none of the above.
PRE LO OIL PRES lamp lights. Engine continues to operate	Engine oil pressure has dropped to 20 psi (138 kPa)	If generator is powering critical loads and cannot be shut down, wait until next shutdown period and then follow step 5 procedure. If engine can be stopped, follow procedures in step 5.
LO OIL PRES lamp lights. Engine shuts down	Engine oil pressure has dropped to 14 psi (97 kPa)	Check oil level, lines and filters. If oil system is OK but oil level is low, replenish. Reset control and restart. Contact an authorized service center if oil pressure is not in the range of 25 to 40 psi (172 to 275 kPa).
OVERCRANK lamp lights and engine stops cranking, or engine runs, shuts down, and LO OIL PRES lamp lights	Possible fuel system problem	Check for empty fuel tank, fuel leaks, or plugged fuel lines and correct as required; check for dirty fuel filter and replace if necessary (see Maintenance section); check for dirty or plugged air filter and replace if necessary (see Maintenance section); reset the control and restart after correcting the problem; contact an authorized service center for service if none of the above.
