Introduction and Description

This package power system is designed to automatically provide standby power to unattended loads during electrical outages. Upon an interruption of normal electrical service this package power system's electrical control circuits will automatically start the engine. The generator will produce electrical power and the Automatic Transfer Switch (A.T.S.) will automatically transfer the electrical loads to the engine-generator set. Upon restoration of normal electrical service the A.T.S. will sense return of the normal commercial power and retransfer the load back to normal commercial power source. The engine control circuits shut off the run signal to the engine generator set.

These package power systems consist of two major components:

1. AUTOMATIC TRANSFER SWITCH (UL LISTED): The Automatic Transfer Switches (A.T.S.) is a wall mount switch designed for inside installation. An electronic exerciser circuit is installed in the A.T.S. as standard equipment.

   • Owner's manual and wiring diagram.
   • Engine manufacturer's instruction manual.
3. Remove main frame hold down bolts, (6).
4. Unit can now be lifted from shipping rails.

Installation

WARNING: PERSONAL INJURY - Before proceeding with the installation, be sure the operation selector switch is in the "stop" position.

General Information

Note: Roof access panels have been provided to check/fill the engine oil and the coolant. Side panels may be removed by removing the thumb screws on the bottom under side of each panel.

These engine generator sets are for outdoor installation. These units must be bolted solidly to a concrete pad. The transfer switch is mounted next to your distribution panel inside the building. Consult a qualified, licensed electrician or contractor to install and wire the transfer switch. The installation must always comply with all national, state, and local codes.

CAUTION: EQUIPMENT DAMAGE - These units must be mounted on a solid concrete pad to prevent air from exiting under the unit. Allowing air to exit under the unit may cause the unit to overheat from lack of proper air flow.

Before beginning the installation process recheck the rating of the generator set and its transfer switch rating. Be certain they can handle the intended load and are compatible with the entrance voltage, phase and current ratings. Plans for installation should be prepared with proper attention to mechanical and electrical engineering detail to assure a satisfactory system installation. The information in this manual is offered only as a guide to finalizing your installation plans. For full service switching the A.T.S. must have a fusible disconnect (circuit breaker) installed before the switch to protect the contacts.

Engine Generator Set Mounting

The unit's main frame should be bolted solidly to a 4 to 6 inch thick cement pad. The engine-generator is mounted on a sub-frame which is attached with special shock mounts to the main frame. This allows the engine-generator free movement without affecting the control panel which is mounted on the main frame. Do not shock mount the main frame. Engine vibration will be transmitted to the control panel causing erroneous start/stop cycles and premature control failure.

These units should be mounted to allow for ample working room around it. Units must be installed in accordance with all local, state and national codes. Consult your local agency having jurisdiction for specific requirements.

Fuel Installation

The fuel supply should be as close as possible to the engine. This will reduce the installation cost of fuel runs. The information in this manual is offered to assist you in providing the proper fuel for your engine. However, this information is only provided to inform you of the engine's requirements and assist in making you aware of the decisions you must make. In no case should the instructions or information provided be interpreted to conflict with any local, state or national codes. If in doubt, always consult your local fire marshal or gas supplier.

WARNING: FIRE HAZARD - All fuel runs should be installed by a licensed fuel supplier.

Connect the fuel supply to the inlet of the fuel solenoid (see table for recommended line size). The pressure at the secondary demand regulator must be four to six ounces psi (per square inch) or 7 to 11 inches W.C. (Water column) for vapor withdrawal units. On units equipped with liquid withdrawal fuel systems full tank pressure is plumbed to the fuellock strainer mounted on the generator rails. The fuel converter mounted on the unit will handle both vaporization of the fuel and pressure reduction.

Installing the Fuel Line

NOTICE: The engine generator sets are properly adjusted before they leave the factory for a specific fuel, either NG (natural gas), LP (liquid propane vapor) or LPG (liquid withdrawal propane). This fuel type is noted in your model number. If it becomes necessary to change the fuel type in the field see information on page 12.

Line Size (vapor system)

Unit location will determine the size of fuel line that is required to supply the engine with a constant fuel pressure. Refer to the tables below for fuel line size, fuel consumption and recommended tank size. For distances of 25 feet and over, a two regulator fuel system is recommended. This is accomplished by installing a primary regulator at the tank which will reduce the tank pressure down to 10 to 15 lbs. A secondary regulator is installed to further reduce the fuel pressure to the required six (6) oz operating pressure. This secondary regulator must be at least 10 feet from the engine generator set. Any closer installation will require a larger line be installed to provide a fuel reservoir. If this is not done, the demand regulator on the unit and the pressure regulator in the fuel line will interfere with each other. When this two (2) stage regulator system is used, a fuel line size of 3/4 to 1 inch is generally adequate for distances up to 200 feet from the primary to the secondary regulator. (Consult your local fuel supplier for your exact requirements). The appropriate line size from the table below is then installed from the secondary regulator to the generator set.

* Allow an additional 3 feet for each standard elbow. Do not use 'street ells' (restrictive).

Fuel Pressure (vapor system)

Correct fuel pressure cannot be stressed enough. The most common cause for inoperative systems is an inadequate or incorrect fuel pressure. Performance of the engine is in direct relation to the correctness of the fuel system. Shown below is a block diagram of a typical L.P. or N.G. Installation.

TWO (2) REGULATOR FUEL SYSTEM

SINGLE REGULATOR FUEL SYSTEM

Reference numbers 1 through 3 in the block diagrams above are fuel lines supplied by customer. Reference number 4 is the engine generator set.

Below is a table of the fuel pressure readings at each reference in the system.

Fuel Pressure Table

Single Regulator (L.P. Vapor only)

Two (2) Regulator System (L.P. Vapor only)

Natural Gas

Notice the preceding tables give two (2) different units of measuring fuel pressure. The first is with a pressure gauge calibrated in ounces per square inch. The second and most accurate is the use of a simple water manometer. A manometer is calibrated in inches of water column.

LP Liquid Withdrawal Systems

When installing a unit equipped the LP liquid withdrawal a primary regulator is not required on the supply tank. The supply line is connected to a liquid withdrawal valve on the supply tank and runs directly to the fuellock strainer mounted on the engine generator set. Normally a 3/8 inch copper line is acceptable for this type of fuel installation. You must be sure that the valve you have connected to on the supply tank is in fact a liquid supply valve and has a drop tube inside the tank that is pulling fuel from the bottom of the supply tank. Before starting the unit you must confirm that you have a good liquid supply at the unit. Engine generator sets equipped for liquid withdrawal will not run properly when supplied with high pressure vapor fuel.

Lubrication

Before starting the engine, check the oil level in the crankcase. If it is low, refill to the full mark with the proper weight/grade of oil as recommended by the engine manufacturer's maintenance instructions. The necessity of using the correct oil, and keeping the crankcase full cannot be over emphasized. Failure to use the proper oil and keep the crankcase properly filled will cause excessive engine wear and shorten its useful life.

Coolant

Before starting the engine, check the coolant level in radiator. If it is low, refill as specified in the engine manufacturer's maintenance instructions. The radiator should be filled to about 1 inch below the filler neck. For additional information on engine coolant requirements see engine manufacturer's maintenance instructions.

Installing the Battery

CAUTION: In the following battery installation procedure, check to be sure the selector switch remains in the "stop" position. This should be your last step before initial start-up.

A customer supplied twelve-volt battery is required to complete the installation. Installation of the highest CCA rated battery, within the correct BCI group, will increase cold weather starting performance. Gel batteries should not be used with the battery tender installed in the generator enclosure.

Installation and servicing of batteries must be performed or supervised only by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries.

When installing or replacing batteries, use the proper group/size starting battery. The battery should be a Maintenance Free lead acid design. Deep cycle batteries will not work for this application.

CAUTION – PERSONAL DANGER

• NEVER dispose of a battery in a fire. The battery is capable of exploding.
• DO NOT open or mutilate the battery. Released electrolyte is known to be harmful to the skin and eyes and to be very toxic.

These engine generator sets are all NEGATIVE ground. Be very careful not to connect the battery in reverse polarity, as this may short circuit the battery charging system on the engine.

CAUTION – A battery presents a risk of electrical shock and high short circuit current. The following precautions must be observed when working with batteries.

1. Remove watches, rings and other metal objects.
2. Use tools with insulated handles.
3. Check both the battery cable ends and the battery posts to be sure they are free of corrosion.
4. Always connect the battery positive cable first and then connect the battery negative cable. When removing the battery cables from the battery reverse the procedure, disconnect the negative cable first and then the positive cable.
5. Be sure all connections are tight and coat the terminals and cable end with dialectic grease.

WARNING – The electrolyte is a diluted sulfuric acid that is harmful to the skin and eyes. It is electrically conductive and corrosive. The following precautions must always be taken.

• Always wear full eye protection and protective clothing.
• Where electrolyte contacts the skin, wash off immediately with water.
• If electrolyte contacts the eyes, flush thoroughly and immediately with water and seek immediate medical attention.
• Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to use a solution of one pound of bicarbonate of soda (baking soda) to one gallon of water. The bicarbonate of soda solution is to be added until the evidence of reaction, foaming, has ceased. The resulting liquid is to be flushed with water and the area dried.

DANGER – Explosive Fire Risk

• Never smoke when near batteries.
• Do not cause a flame or spark in the battery area.
• Always discharge static electricity from your body before touching batteries by first touching a grounded metal surface.

Servicing Batteries

Batteries used on these units may over time lose water. This is especially true if you are using a trickle charger to maintain your battery. When refilling the battery with water use only distilled water. Tap water will shorten the service life of the battery.

Never fill the battery above the fill line. Over filling above the upper level line may cause the electrolyte to overflow, resulting in corrosion to the engine or nearby parts. Immediately wash off any spilled electrolyte following the procedure above.

NOTE: Always make sure that a new battery is fully charged before installing it on a generator set. Failure to do so can cause damage to the engine control module in the generator set.

All connections must be clean and tight. Check the electrolyte (fluid) in the battery periodically to be sure it is above the plates. Never allow the battery to remain in a discharged condition.

Connecting the Battery Charger & Blockheater

A three-stage battery charger is provided standard for all 12 volt standby systems. The standard charger is an Automatic Battery Charger & Maintainer. This Charger has three rates of charging. During the first stage, known as BULK Charging, the charging current is limited to 2 Amps at a voltage of up to 14.5 volts. The green LED will blink during this stage. During stage two, known as ABSORPTION Charging, the charging voltage is held at 14.5 volts and the charging rate gradually reduces the amount of current (amps) flowing to the battery. The green LED will also blink during this stage. Stage three is called MAINTENANCE Charging. During this stage the voltage will drop to 13.3 volts and the charge rate will drop to as low as .1 amps. This keeps your batteries in a fully charged condition without over charging them. During this stage the green LED is constantly lit.

NOTICE: The trickle charger is not intended to recharge a battery which has become completely discharged. It is designed to produce just enough current to maintain a fully charged battery.

The battery tender receptacle is to be powered by a GFCI circuit and installed in accordance with the United States National Electric Code. These AC wires can be run in the same conduit as the other AC leads from the generator. It is suggested that this circuit be fused for 15 amps, then both the battery charger and the block heater can be connected to the same circuit. A 120 volt duplex receptacle is mounted on the generator along side circuit breaker panel, the battery tender is shipped already plugged into the receptacle. The engine block heater installed on this unit should also be plugged in this receptacle. The block heater is thermostatically controlled and when plugged in will maintain the engine coolant temperature between 100 and 120 degrees F.

Mounting the Automatic Transfer Switch (A.T.S.)

WARNING: FIRE HAZARD - All wiring must be done by a licensed electrician, and must conform to the national electrical code and comply with all state and local codes and regulations. Check with the local authorities before proceeding!

Installation Notes

Because of the many different types of service, feeder, and distribution equipment, no specific wiring instructions can be provided. It is recommended that only copper wire be used. In all cases it is essential that while the load is connected to the generator, there can be absolutely no feedback from the generator to the power line or the power line to the generator. When properly installed, the normal A.T.S. Control and safety systems will eliminate all paths for feedback.

To wire the automatic transfer switch into the existing wiring, first determine which circuits will be on the emergency load circuit. If the entire load is to be transferred, the transfer switch can be wired in directly after the watt-hour meter and the service entrance, providing the service entrance ampere rating is within the transfer switch's rated capability.

If only specific circuits are to be powered under emergency power failure conditions, an additional distribution panel designated "emergency distribution panel" must be installed. All selected emergency circuits are removed from main distribution panels and installed in the emergency distribution panel. The A.T.S. is then installed between the main panel and the emergency distribution panel. Suggested circuits: freezer, refrigerator, furnace, emergency lights, sump pump, emergency outlet circuits, etc. Total running load must not exceed generator rating.

A.C. Electrical Connections

NOTICE - CLASS 1 WIRING METHODS ARE TO BE USED FOR ALL FIELD WIRING CONNECTIONS TO TERMINALS OF A CLASS 2 CIRCUIT

Note: This symbol ⚡ always indicates ground where used.

INSTALLERS NOTE:

To access the AC and DC interconnections on this unit, open the single door on the right hand side of the units. Then remove the safety panel covering the mainline circuit breaker. All connection are behind this panel.

Neutral Lugs

These neutral lugs are isolated from ground and provided for you to connect your neutral wire from the transfer switch to. The lugs on the 90 kW will handle wire sizes #1 AWG to 600 MCM and should be torqued to 300 in. lbs. The lugs on the 60 kW will accommodate #4 AWG to 300 MCM and should be torqued to 250 in. lbs.

120 Volt Terminal Block

This terminal block is provide for the 120 volt/ 15 amp feed from customers distribution panel for the block heater and the trickle charger.

WARNING: A main line circuit breaker has been provided inside the generator housing. During all wiring installations make sure the breaker is in the off position and the generator operation switch is in the off position.

WARNING: EQUIPMENT DAMAGE - When installing a Three Phase 240 volt system be sure you know which lead is the high voltage "wild" leg (208 Volt line to neutral). The generator normally carries the high voltage on the G2 lead.

The load current carrying wires (L) and (T) must be sized to handle the maximum load current without excessive voltage drop. By code, the wire must be heavy enough to handle the full current rating of the main line circuit-breaker (or fuse) in the entrance (or sub-panel) protecting the contactor switch.

All wires should be installed in rigid or flexible conduit. (Knock-outs are provided in the connection box).

See the manual shipped with the Automatic Transfer Switch for connection locations in the switch. Connections in each switch will vary depending on the type of switch and the manufacturer.

Grounding

A grounding lug has been provided on the engine generator set to be grounded to earth ground if required. Check with your local codes. Generally a 6 foot copper rod driven into the earth will provide a proper earth ground.

D.C. Electrical Connections

NOTE: There are various DC connectors on the engine that have nothing connected to them. This was done intentionally; these connectors are for END OF LINE TESTING and other various diagnostic tests. They are not used during normal operations and can just be ignored.

All DC connections are completed in the small box just below the engine control cabinet. In addition, there are two small fuses mounted on the bottom of the engine control cabinet that protect both the engine control and all the other DC connections.

Customer Remote Start Connections Terminals

The two remote start leads from the Automatic Transfer Switch are connected to the two terminals marked 1 & 23. The wire in terminal labeled #1 is Battery Negative and the wire in the terminal labeled #23 is your Remote Start lead. Closing these two leads together will signal the DSE 7310 to go into an auto-start mode and start up the engine generator. Depending on the distance, 14 to 16 gauge stranded wire should be used. It is suggested that these wires be labeled S1 and S23. The terminal blocks are designed to use terminal lugs on all wires and the screws should be torqued to 9.6 in. lbs.

Note: Any relay closure can be used to start and stop this generator. As long as the contact stays closed the engine generator set will continue to run. Once the relay is opened the unit will shut down and remain in the standby mode until the remote start relay is closed again.

ESTOP- & ESTOP+ (Remote Emergency Stop terminals)

These two terminals are shipped with a jumper installed. If your application requires the installation of a Remote Emergency Stop switch, remove the jumper and wire your switch to these terminals. This unit will not start and run without either the jumper installed or a remote N/C switch installed.

When the remote start signal is received it will time out the start delay (5 Seconds) and then start the engine generator set. When the remote start signal is lost (relay opened up) the module will shut the engine generator set down after the cool down timer has timed out. The module will return to the auto start mode and await the next start signal.

E. LAMP TEST/HORN RESET: This button silences the audible alarm if it is sounding and illuminates all of the LEDs as a lamp test feature. When configured and fitted to a compatible engine ECU, pressing this button in STOP/RESET mode after pressing the START button (to power the ECU) will cancel any "passive) alarms on the engine ECU.

F. START: This button is active only in the MANUAL or STOP/RESET mode. Pressing this button in the MANUAL mode will start the engine locally for testing. The engine will continue to run until either the STOP/RESET or the AUTO button is pressed. Pressing this button with the control in the STOP/RESET mode will turn on the CAN engine ECU (when correctly configured and fitted to a compatible engine ECU).

Initial Start Up

WARNING: EQUIPMENT DAMAGE - DO NOT jump start these engine generator sets. Starting these units on a low battery or jump starting them will cause damage to the engine control module.

Use the following check list to verify correct installation before starting the engine:

Note: Roof access panels have been provided to check/fill the engine oil and the coolant. Side panels may be removed by removing the thumb screws on the bottom under side of each panel.

1. Engine oil. Fill as required with proper grade/qty.
2. Engine coolant. Fill as required with proper mixture.
3. Unit mounting base properly bolted down.
4. Clearance for service and maintenance on all sides.
5. Proper fuel line material and size.
6. All fuel line connections tight.
7. Fuel line protected and a moisture trap installed (may be required for N.G.).
8. Correct LP/NG pressure 4-6 Oz. (7-11" Wc).
9. Battery connections clean and tight.
10. Battery fully charged.
11. All AC and DC wiring installed and properly protected.

After completing the above checklist, the engine-generator set is ready for the initial start-up test.

Starting Procedure

MANUAL MODE

WARNING: EQUIPMENT DAMAGE - BEFORE ATTEMPTING TO START THIS UNIT COMPLETE YOUR PRESTART CHECKLIST AND INSURE THE GENERATOR MAINLINE CIRCUIT BREAKER IS IN THE PROPER POSITION PRIOR TO STARTING. STARTING THIS UNIT WITHOUT IT PROPERLY CONNECTED CAN CAUSE SERIOUS PERSONAL INJURY OR EQUIPMENT DAMAGE.

1. Depress the manual mode button on the control panel. The small LED light next to it should come on.
2. Press the start button- The DSE7310 will send a start signal to the ECU on the engine. The engine ECU will then energize the fuel solenoid and start the cranking cycle (10 seconds on and 10 seconds off).

NOTE: There is no start delay in this mode of operation. If the engine fails to start during this cranking period the starter motor is disengaged and goes into a rest mode after which a second attempt is made to start the engine. Should this sequence continue through 3 cranking cycles the start sequence will be stopped and the display will show 'FAILED TO START'.

3. All engine functions are controlled by the ECU on the engine. The ECU on the engine will send information signals to the DSE7310 via the CAN connections to indicate oil pressure, water temperature, etc for the display on the engine control. All shutdown functions are also controlled by the ECU on the engine, what you see displayed on the DSE7310 display is what is happening inside the ECU on the engine.

The AC output readings displayed on the DSE7310 are collected through the AC interface harness wired in the generator control box. An shutdowns related to the AC output are not a function of the engine ECU but are based on information collected in the DSE7310 via this AC harness.

4. During manual operation the load will not normally be applied to the generator. But caution must be used, if the line power should fail or be turned off to the transfer switch during manual operation the load may be applied to the generator.

With the engine running smoothly check the no load voltage and frequency on the digital display. The voltage should be 208/240/ 480 AC depending on which model you have and a frequency of 59.5 To 60.5 hertz (Hz).

If you have the proper voltage at the generator the next step is to check the voltage at the generator terminals in the Automatic Transfer Switch. The voltage between the G1 and the G3 terminals should be the same as it was on the generator front panel. The voltage should also be checked between the hot terminals (G1 and G3) and the G-N to be certain of a balanced voltage output and a solid neutral connection. The voltage between G1 and G-N should be about 120 volts AC (277 on 480 units). The same approximate voltage should be found between terminals G3 and G-N (120 volts AC).

On three phase panels the G2 voltage level should also be checked. ON 240 VOLT (DELTA) SYSTEMS BE SURE YOU KNOW WHERE THE HIGH VOLTAGE "WILD" LEG IS. IT MUST BE IN THE SAME LOCATION ON THE LINE SIDE AS IT IS ON THE GENERATOR SIDE. (i.e. if it's on L-3 on the line side it must be on G-3 on the generator side.

Notice: If for any reason during the check out procedure the voltage and frequency are not correct, depress the STOP/RESET button and correct the trouble before proceeding.

5. Stopping - There are two ways to stop the unit when it is in the manual mode. Pressing the STOP/RESET button will stop the unit immediately. Pressing the AUTO mode button will stop the unit but only after the cool down timers have timed out and there is no remote start signal being sent to the unit.

AUTO MODE

To activate the automatic start mode you will just need to depress the AUTO button, the LED indicator beside the button confirms that the unit is in automatic start mode.

Changing the Fuel Type

CAUTION: EQUIPMENT DAMAGE - Do not make any fuel adjustments or governor adjustments until all pressure readings are in compliance with specification. See fuel pressure charts (tables 1, 2, and 3).

These engine/generator sets are very easy to convert between LP or NG. As the engine timing is controlled by the ECU on the engine you only need to tell it what fuel you want to operate on. In the customer connection box there is a fuel selection terminal. A small rocker switch has been provided on the underside of the engine control cabinet (see ref G on Page 9) for this purpose.

Opening the rocker switch will tell the ECU mounted on the engine that you are operating on NG Fuel. Closing the rocker switch will tell the ECU that the fuel being supplied is LP. The ECU will then reprogram the engine to operate on the proper fuel.
