Common problems

Generator set stops suddenly
Cause: Low oil pressure shutdown
Fix: Check for oil leaks. Check the oil level and add oil if necessary
The generator set cranks but does not start, starts hard, lacks power, or operates erratically
Cause: Air cleaner clogged
Fix: Clean and/or replace the air cleaner
The generator set does not crank
Cause: Battery weak or dead
Fix: Recharge or replace the battery
No AC output
Cause: Line circuit breaker in the OFF position
Fix: Place the circuit breaker in the ON position
Controller internal circuit protection activated Accy PwrOver Warning
Fix: Press OFF to reset. Contact an authorized Kohler distributor/dealer for service
Under Voltage — Paralleled; delay 10 sec.; display cleared on Press AUTO or OFF Voltage L1-L2 Low Warning
Under Frequency — Paralleled; delay 10 sec.; display cleared on Press AUTO or OFF Frequency Low Warning
This generator has paralleled to the other generator and is verifying that the metering is connected and establishing the connection direction ChkngMeter
Cause: Status message appears the first time the two generators are paralleled
This generator has been stopped by generator management because it is not presently needed to supply the load. The generator is available and will start if it is needed again Generator Management Off
This generator has absorbed more than 25% reactive power (magnetic excitation current) for 20 seconds LossOfField
Cause: Generator voltage on this generator is not calibrated correctly; Generator voltage on other generator is not calibrated correctly; Bus voltage on this generator is not calibrated correctly; Bus voltage on the other generator is not calibrated correctly
This generator does not know if the metering is connected or the orientation of the connection. This means that the generators can’t share load accurately until this information is known MeterUnknown
Cause: System commissioning and startup not yet complete
Fix: See the APM instructions
The two generators that are intended to be paralleled have incompatible model numbers CfgModelNum
Cause: Incorrect configuration of one of the generators. Different generator types
Fix: The paralleled generator sets must be the same kW model. (i.e. two 14 kW or two 20 kW models.)
The system voltage of the two generators intended to be paralleled is not the same. Because the system does not know which voltage is correct, the generators will not be allowed to start CfgSysVolt
Cause: One of the two generators is incorrectly configured; Intermittent connections on RBUS network wiring
The primary controller has lost communication with the secondary controller. (A secondary controller was detected, then communication was lost.) LossOfComm2
Cause: RBUS disconnected, secondary controller battery disconnected, updating firmware in secondary controller, or intermittent RBUS connections
The power metering on this controller gives a signal that is not consistent with the system configuration. Reversing the power direction does not resolve the problem ErraticSig
Cause: Bad wiring to the CT; Too much tension on wires from the CT to the controller

Procedures

RDC2 Voltage Calibration Using SiteTech adjustment

Tools: digital voltmeter, personal computer, SiteTech software

Connect PC to controller via USB
With generator off, connect multimeter across L1/L2 (AC volts)
Start generator set
Compare voltmeter reading to controller display
Calculate new Genset Calibration Factor Voltage using (Vmeter / Vcontrol) x Fold = Fnew
Enter new value into SiteTech and click Apply Changes
Verify voltmeter matches controller display
Repeat for L2-L3 and L3-L1 if three-phase
Press OFF to stop generator set

RDC2 Voltage Calibration Using the Controller Keypad adjustment

Tools: digital voltmeter

With generator off, connect digital multimeter across L1 and L2, set to AC volts
Start generator set with RUN button
Navigate to Generator Metering menu, press Select; Volts L1-L2 displayed
Press Select; voltage number flashes
Use up/down arrows to match voltmeter reading
Press Select to confirm
Step to Return screen
Press OFF to stop generator set

VSC Current (Load) Calibration Using the Controller Keypad adjustment

Tools: clamp-on DC current probe or DC current meter

Connect DC current probe/clamp meter to measure generator current
Start generator with RUN button
Adjust system voltage to obtain rated current output with battery bank attached (or use load bank)
Trip output breaker
Navigate to Generator Metering menu, select Generator Load
Press and hold Select for No-Load Calibration; verify breaker open, confirm Yes
Close output breaker; verify rated output current, confirm Yes
Verify displayed load is correct; recalibrate if necessary
Press OFF to stop generator set

Firmware Update Using SiteTech maintenance

⚠ Do not load RDC2.4 firmware onto a red- or green-board controller

Tools: personal computer, USB cable, SiteTech software

Download latest firmware file (.bin) from Kohler Power Resource Center or dealer portal
Connect controller to PC via USB cable
Start SiteTech; program recognizes connected device
Click Update Firmware
Browse to and select firmware file, click Open
Verify current/new version and file name, click Update Firmware
Wait for 'Firmware Updated Successfully' message, click Close

Setting the OnCue Password, RDC2 and VSC operation

Press Select then down arrow to Networking Information menu
Press Select for Networking Status
Press Down arrow for Networking Configuration
Press Select for Reset OnCue Password
Press and hold Select until 'Reset OnCue Password? No' appears
Press Up arrow to change No to Yes
Press Select to reset; serial number and new password display for 10 seconds
