(2)Disconnect the power to the battery charger, if equipped. (3) Remove the battery cables, negative (--) lead first. Reconnect the negative (--) lead last when reconnecting the battery. Follow these precautions to prevent the starting of the generator set by the remote start/stop switch.

Battery

WARNING

Sulfuric acid in batteries.

Can cause severe injury or death.

Wear protective goggles and clothing. Battery acid may cause blindness and burn skin.

WARNING

Explosion.

Can cause severe injury or death. Relays in the battery charger cause arcs or sparks.

Locate the battery in a well-ventilated area. Isolate the battery charger from explosive fumes.

Battery electrolyte is a diluted sulfuric acid. Battery acid can cause severe injury or death. Battery acid can cause blindness and burn skin. Always wear splashproof safety goggles, rubber gloves, and boots when servicing the battery. Do not open a sealed battery or mutilate the battery case. If battery acid splashes in the eyes or on the skin, immediately flush the affected area for 15 minutes with large quantities of clean water. Seek immediate medical aid in the case of eye contact. Never add acid to a battery after placing the battery in service, as this may result in hazardous spattering of battery acid.

Battery acid cleanup. Battery acid can cause severe injury or death.

Battery acid is electrically conductive and corrosive. Add 500 g (1 lb.) of bicarbonate of soda (baking soda) to a container with 4 L (1 gal.) of water and mix the neutralizing solution. Pour the neutralizing solution on the spilled battery acid and continue to add the neutralizing solution to the spilled battery acid until all evidence of a chemical reaction (foaming) has ceased. Flush the resulting liquid with water and dry the area.

Battery gases. Explosion can cause severe injury or death. Battery gases can cause an explosion. Do not smoke or permit flames or sparks to occur near a battery at any time, particularly when it is charging. Do not dispose of a battery in a fire. To prevent burns and sparks that could cause an explosion, avoid touching the battery terminals with tools or other metal objects. Remove all jewelry before servicing the equipment. Discharge static electricity from your body before touching batteries by first touching a grounded

metal surface away from the battery. To avoid sparks, do not disturb the battery charger connections while the battery is charging. Always turn the battery charger off before disconnecting the battery connections. Ventilate the compartments containing batteries to prevent accumulation of explosive gases.

Battery short circuits. Explosion can cause severe injury or death.

Short circuits can cause bodily injury and/or equipment damage. Disconnect the battery before generator set installation or maintenance. Remove all jewelry before servicing the equipment. Use tools with insulated handles. Remove the negative (--) lead first when disconnecting the battery. Reconnect the negative (--) lead last when reconnecting the battery. Never connect the negative (--) battery cable to the positive (+) connection terminal of the starter solenoid. Do not test the battery condition by shorting the terminals together.

Engine Backfire/Flash

Fire

WARNING

Fire.

Can cause severe injury or death.

Do not smoke or permit flames or sparks near fuels or the fuel system.

Servicing the fuel system. A flash fire can cause severe injury or death.

Do not smoke or permit flames or sparks near the carburetor, fuel line, fuel filter, fuel pump, or other potential sources of spilled fuels or fuel vapors. Catch fuels in an approved container when removing the fuel line or carburetor.

Servicing the air cleaner. A sudden backfire can cause severe injury or death. Do not operate the generator set with the air cleaner removed.

Combustible materials. A fire can cause severe injury or death.

Generator set engine fuels and fuel vapors are flammable and explosive. Handle these materials carefully to

minimize the risk of fire or explosion. Equip the compartment or nearby area with a fully charged fire extinguisher. Select a fire extinguisher rated ABC or BC for electrical fires or as recommended by the local fire code or an authorized agency. Train all personnel on fire extinguisher operation and fire prevention procedures.

Exhaust System

WARNING

Carbon monoxide.

Can cause severe nausea, fainting, or death.

The exhaust system must be leakproof and routinely inspected.

Generator set operation. Carbon monoxide can cause severe nausea, fainting, or death. Carbon monoxide is an odorless, colorless, tasteless, nonirritating gas that can cause death if inhaled for even a short time. Avoid breathing exhaust fumes when working on or near the generator set. Never operate the generator set inside a building. Never operate the generator set where exhaust gas could seep inside or be drawn into a potentially occupied building through windows, air intake vents, or other openings.

Carbon monoxide symptoms. Carbon monoxide can cause severe nausea, fainting, or death. Carbon monoxide is a poisonous gas present in exhaust gases. Carbon monoxide is an odorless, colorless, tasteless, nonirritating gas that can cause death if inhaled for even a short time. Carbon monoxide poisoning symptoms include but are not limited to the following:

D Light-headedness, dizziness

DPhysical fatigue, weakness in joints and muscles

DSleepiness, mental fatigue, inability to concentrate

or speak clearly, blurred vision D Stomachache, vomiting, nausea

If experiencing any of these symptoms and carbon monoxide poisoning is possible, seek fresh air immediately and remain active. Do not sit, lie down, or fall asleep. Alert others to the

possibility of carbon monoxide poisoning. Seek medical attention if the condition of affected persons does not improve within minutes of breathing fresh air.

Carbon monoxide detectors. Carbon monoxide can cause severe nausea, fainting, or death. Install carbon monoxide detectors on each level of any building adjacent to the generator set. Locate the detectors to adequately warn the building’s occupants of the presence of carbon monoxide. Keep the detectors operational at all times. Periodically test and replace the carbon monoxide detectors according to the manufacturer’s instructions.

Safety Precautions and Instructions

TP-6905 6/14

Propane (LP)—Adequate ventilation is mandatory. Because propane is heavier than air, install propane gas detectors low in a room. Inspect the detectors per the manufacturer’s instructions.

Natural Gas—Adequate ventilation is mandatory. Because natural gas rises, install natural gas detectors high in a room. Inspect the detectors per the manufacturer’s instructions.

Gas fuel leaks. Explosive fuel vapors can cause severe injury or death. Fuel leakage can cause an explosion. Check the LP vapor gas or natural gas fuel system for leakage by using a soap and water solution with the fuel system test pressurized to 6--8 ounces per square inch (10--14 inches water column). Do not use a soap solution containing either ammonia or chlorine because both prevent bubble formation. A successful test depends on the ability of the solution to bubble.

Section 2 Generator Set Operation 15

2.3 Exercising the Generator Set

Operate the generator set without load every week or every other week for 20 minutes. Perform all of the prestart checks before starting the exercise procedure. See Section 2.5 for instructions to set the automatic exerciser.

2.4 Generator Set Operation

2.4.1Local Starting and Stopping

Start: Press the RUN button to immediately start the generator set.

Stop: Press the OFF button. The engine stops.

Run the generator set with no load for at least 2 minutes to ensure adequate engine cooldown.

2.4.2Automatic Starting and Stopping

An automatic transfer switch monitors the utility power and signals the generator set to start when utility power is lost. The ATS then transfers the load to the generator set.

When utility power is restored, the transfer switch transfers the load back to utility, runs the generator set with no load to cool down the engine, and then stops the generator set engine. The electric fans continue to run for two minutes after the engine shuts down to evacuate the engine compartment.

2.4.3Remote Starting and Stopping

A remote switch connected to terminals 3 and 4 can be used to start and stop the generator set. Close the switch to start and run the generator set. Open the switch to stop the generator set.

Run the generator set with no load for at least 2 minutes to ensure adequate engine cooldown.

2.4.4Engine Start Crank Cycle

The controller attempts to start the generator set three times (three crank cycles, 15 seconds crank and 15 seconds off). If the generator set does not start in three attempts, the system shuts down on an overcrank fault. See Section 2.6.

Pressing the OFF button during the crank cycle stops the cranking. No other buttons are acknowledged during the crank cycle.

2.4.5Engine Cooldown

The engine cooldown time delay allows the engine to run after the loads have been removed.

The engine cooldown time delay is set to 5 minutes. The engine stops before the cooldown time delay expires if the temperature drops below the cooled-down temperature level, or if the temperature rises above the high limit during the cooldown cycle.

The electric fans continue to run for two minutes after the engine shuts down to evacuate the engine compartment.

If a transfer switch other than the Model RXT is used, an additional engine cooldown time delay may be programmed on the transfer switch. To allow the smart engine cooldown on the RDC2 controller to operate most efficiently, set the cooldown time on the transfer switch controller to zero or the minimum time allowed. Refer to the instructions provided with the transfer switch for more information.

2.4.6Automatic Operation with Model RXT Transfer Switch

The Model RXT transfer switch connects to the RDC2 controller through the ATS interface board on the transfer switch. Also see Section 2.7, Model RXT Transfer Switch Operation.

The RDC2 controller must be in AUTO mode for automatic transfer switch operation.

Automatic Start

The RDC2 controller receives utility source voltage sensing data from the Model RXT transfer switch.

1.If the utility source voltage falls below an acceptable level, the controller starts the engine start time delay.

2.If the utility source is not restored before the time delay expires, the generator set starts.

3.After the Normal-to-Emergency time delay, the ATS is signaled to transfer the load to the emergency source.

16 Section 2 Generator Set Operation

TP-6905 6/14

Automatic Stop

1.When the utility source is restored, the Emergency-to-Normal time delay starts.

2.When the Emergency-to-Normal time delay expires, the load is transferred to the utility.

3.The generator set stops.

2.4.7Automatic Operation with Model RDT or RSB Transfer Switches

If a Kohler Model RDT or RSB transfer switch is used, the engine start contacts from the ATS must be connected to engine start leads 3 and 4 on the generator set.

The RDC2 generator set controller must be in AUTO mode to respond to remote start/stop signals from an ATS or remote switch. Press the AUTO button on the RDC2 controller to put the generator set into automatic mode.

Automatic Start

The engine start contacts on the ATS close to signal the generator set to start, and remain closed while the generator set is running.

Automatic Stop

The engine start contacts on the ATS open to signal the generator set to stop.

2.5 Exercise

The RDC2 controller can be set to automatically run the generator set at the same time and day every week or every other week. Exercising the generator set every week or every two weeks is required in order to keep the engine and alternator in good operating condition.

Three exercise modes are available: unloaded cycle, unloaded full speed, and loaded full speed. See Sections 2.5.1 through 2.5.3 for information about the exercise modes. A loaded exercise can be set at the RDC2 controller only if a Model RXT transfer switch is connected.

Note: With the RDT and RSB transfer switches, it is possible to have two exercise settings (one unloaded exercise set at the generator set controller, and another exercise set at the ATS controller). If the exercise times overlap, the ATS exercise setting takes priority.

If a Model RDT or RSB transfer switch is used, refer to the instructions provided with the transfer switch to set a loaded exercise at the ATS, if desired.

2.5.1Unloaded Cycle Exercise with Complete System Diagnostics

An unloaded cycle exercise runs the generator set without signalling the transfer switch to transfer the electrical load from the utility source to the generator set. The Unloaded Cycle exercise with diagnostics is the recommended exercise mode and is the factory-default exercise setting.

The Unloaded Cycle exercise runs the engine for 20 minutes in the cycle shown in Figure 2-1 and described below.

DRuns at reduced speed for 10 minutes to warm up and exercise the engine.

D Ramps up and runs at full speed for 3 minutes. Engine diagnostics are performed during this full-speed portion of the cycle, which provides the best test of engine and alternator power backup capability. Diagnostic tests at full speed can identify potential problems with the power output and alert the operator before an emergency event.

D Ramps down and runs at reduced speed for 5 minutes to cool down the engine before shutting down automatically.

Figure 2-1 Unloaded Exercise Cycle

System Diagnostics

During the unloaded cycle exercise, the controller monitors the following data. The controller display indicates an unloaded exercise run during the diagnostics, unless a fault is detected as described below.

TP-6905 6/14

Section 2 Generator Set Operation 17

D ATS connection. The controller verifies that the Model RXT ATS interface board is connected.

DBattery voltage. Battery voltage is checked before exercise to verify engine starting capability. Battery voltage provides a measurement of battery health. If the controller detects low battery voltage, low battery or low charging battery is displayed and the exercise does not start.

D Coolant level check. The coolant level is checked.

D Communication integrity tests. J1939, RBUS, Ethernet, and USB are monitored for messages indicating that the controller and wiring are reliable.

DEngine speed. Engine speed is measured at low speed and full speed. An overspeed or underspeed condition will result in a fault condition and shutdown.

D Generator output frequency and voltage.

Operating the generator at full speed allows the RDC2 controller to check the output power for correct voltage, frequency, and stability. When the engine is running at full speed, the controller verifies that the voltage and frequency are within acceptable limits. A fault message is displayed if the voltage or frequency is out of range.

D Oil pressure. Oil pressure is verified to ensure proper lubrication of critical engine components. Pressure is monitored at both low and full speeds. If the oil pressure is low, low oil pressure is displayed and the generator set shuts down.

2.5.2Unloaded Full-Speed Exercise

The unloaded full speed exercise runs the generator set at full speed for 20 minutes without transferring the load.

To set an unloaded full speed exercise, follow the procedure in Figure 2-3 and select Exercise Mode: Unloaded Full.

2.5.3Loaded Full-Speed Exercise (with RXT only)

A loaded exercise starts the generator set, ramps up to full speed, and then transfers the electrical load from the utility source to the generator set. The load is transferred back to the utility source before the generator set shuts down.

Note: With a loaded exercise, power to the building is lost for up to 10 seconds during load transfer.

For a loaded exercise controlled by the RDC2 controller, a Model RXT transfer switch must be connected to the

generator set. To set a loaded exercise, follow the procedure in Section 2.5.8 and select Exercise Type: Loaded.

For a loaded exercise with a transfer switch other than a Kohlerr Model RXT, program the exercise at the transfer switch controller. Refer to the transfer switch operation manual for instructions.

2.5.4Shutdown During Exercise

The following advanced diagnostic operation applies to RDC2 controllers with firmware versions 5.04 and higher.

If the generator set shuts down on a fault during an exercise, the controller will try to restart the engine. If the engine starts, the generator set will run at full speed for two minutes and then stop. The event history will show Advanced Diagnostic Active. The exercise schedule is maintained.

If the engine does not start, the shutdown message will be displayed. Correct the fault condition and reset the fault as described in Section 2.6.

2.5.5Power Failure During Exercise

If the utility power is lost during an unloaded exercise, the ATS transfers to the emergency source, the exercise is ended and the control remains in the AUTO mode.

If the utility power is lost during a loaded exercise, the exercise is ended. The ATS remains in the emergency position and the control goes into the AUTO mode.

The generator set continues to run and supply power to the load for the duration of the utility power outage. When Utility power is restored, the ATS will re-transfer to the utility source through normal timing sequences.

2.5.6Exerciser Reset

To reset the exerciser to run at a different day and/or time or to change the exercise mode, follow the procedure in Section 2.5.7 to change the exerciser settings.
