Site Planning

Room Size Open frame generators must be protected from the environment while having good ventilation

and cooling. Here are some considerations for planning a generator room or enclosure:

S Never use the Genset room for storage as well. S The room must be large enough to contain the genset and all the accessories, such as

batteries and their charging system, transfer switch and other controls, and elements of the cooling and fuel systems.

S A minimum of 2 feet (preferably 4 feet), must be allowed on the two sides of the engine

for service access.

S On the generator end of the engine, allow a space equal to the length of the generator

(generator length only, not the entire genset).

S At the front of the engine, 4 feet of clearance is preferable. Allow clearance between

hot parts of the system (exhaust) and structural members of the building.

S Certain safety and building codes may require the genset room not to be used to house

any other mechanical or electrical equipment.

General Information 2‐3MN2408

Room Location Often a separate building located on the site away from the main building is the most simple and

cost effective. Major considerations when housing the genset in a separate building are:

S Maintain the building at a satisfactory temperature year round (to meet applicable

codes).

S Assure the genset is not located so far from the emergency loads that reliability is

compromised.

S The floor's load carrying capacity must be checked and must exceed the weight of the

genset and its associated equipment.

S Engine Cooling System

A genset with an engine mounted radiator is the least costly to install; however, the room must be located in a place where sufficient radiator cooling air can be brought into and exhausted from the room.

S Exhaust System

The exhaust system must minimize exhaust restriction. Exhaust restriction must be limited to 3 in. Hg (76 mm Hg) maximum, to ensure proper engine operation. The exhaust system should be as short and have as few bends as possible.

S Room Air

If the genset is cooled with an engine mounted radiator, and sufficient air is brought into and exhausted from the room to satisfy the radiator cooling requirements and the combustion air requirements, the room will not overheat when the genset is running. If a remote mounted radiator or a heat exchanger is used, and adequate air is circulated through the room to keep it at a reasonable temperature, there will be adequate air for combustion.

S Fuel Tanks (Diesel Only)

Locate the fuel storage tank as near the genset as possible. This will minimize the cost of fuel system installation and will maximize fuel system reliability.

S Controls and Transfer Switch

Locate the control switch gear as close to the emergency loads and the genset as practical. This will minimize the chances that a failure of the power line to the emergency load will go undetected. In locating the switchgear, accessibility for service and maintenance must be considered.

S Genset Noise

Internal combustion engines produce noise, so the room should be located away from occupied buildings. In addition the genset room can be treated to reduce noise transmission. In locating the genset room, both engine, fan and exhaust noise must be considered.

If noise within the genset room, or noise transmitted to the surrounding parts of the building are a concern, then the room must be made large enough to allow for installation of noise attenuating walls and noise absorbing walls. Light weight concrete blocks filled with sand or special “sound block” concrete blocks are commonly used. Noise attenuating, tight fitting windows and doors also help reduce noise transmission to the rest of the building. A double-walled room should be considered. Vibration isolators under the genset rails will also reduce the transmission of noise through the floor.

S Code Requirements

Building and safety codes deal with engine location. These requirements are concerned with fire rated walls, a location that minimizes the possibility of damage to the genset and interruption of the emergency system due to storms, foods, fire, vandalism, etc.

Codes often deal with the need to maintain certain temperatures in the genset room and with fuel system location. The most important codes in the USA are the National Fire Protection Association Code Numbers 99 and 110, but local codes must also be observed.

2‐4 General Information MN2408

Foundation Design WARNING: An open bottom stationary engine generator set must be installed over noncombustible

materials and shall be located such that it prevents combustible materials from accumulating under the generator set.

Foundation Checklist

A. Evaluate if a separate, isolated foundation is required for the application. B. Observe local codes on soil bearing capacity freezing and thawing. C. Design the separate foundation for the genset and specify the appropriate concrete mix. D. Determine if the application requires vibration isolators and if so, order as a factory option.

The foundation must be strong enough to support the weight of the genset and its associated equipment, must prevent any deflection of the genset base and absorb vibration produced by the rotating and reciprocating masses.

Setting The Genset On An Existing Concrete Floor Slab

S If an existing floor is used, the floor slab must be strong enough to carry 1.50 times the

genset wet weight (including coolant and oil) to accommodate dynamic loads.

S The actual mounting arrangement (ie., surface area in contact with the floor) will

determine the compressive strength required.

S The genset should be securely fastened to the floor slab with expansion anchors that fit

the mounting holes shown on the genset installation diagram.

S For installations not expected to be permanent, elastomer pad with non-slip surface

placed between the base and the floor will also prevent movement.

S Any floor/slab surface should be as flat as possible to prevent sub-base deflection.

Vibration Isolators

S Mounting to the pad, will result in overall reduced motion on other parts of the genset.

The trade-off is that slightly more vibration is transmitted to the structure.

S A more common practice when mounting to a concrete pad is to use vibration isolators.

The two most common types of vibration isolators are steel spring and elastomer pad. The primary purpose of vibration isolators is to reduce the noise and vibration which would be transmitted from the genset to the foundation or supporting structure.

S A simple and effective method of mounting and applying pad type isolators is to place

non-skidding type isolation pads directly between the sub-base and floor. The number of pads required will be determined by the load bearing capability of the pads and the genset's weight.

Figure 2‐1 Typical Installation of Spring Type Isolator

General Information 2‐5MN2408

S Steel spring isolators are a very effective and commonly used. Steel spring isolators

are typically 95-98% efficient (reduces the transmitted vibration 95-98%) while a pad type can be 75-88% efficient. Spring isolators also level the genset sub-base in the event the foundation pad is not perfectly level.

Spring steel isolators offer the highest level of vibration isolation, however higher levels of vibration (although not detrimental) may be seen on some areas of the genset when mounted on steel springs, due to the (almost) total isolation from the foundation. The base of most steel spring isolators contains a non-skid pad. The base should be mounted to the foundation pad as shown in Figure 2‐1 or as recommended by the isolator manufacturer.

A common practice is to pour a concrete pad directly on top of the floor slab and to mount the genset on this pad. The purpose of the pad is to facilitate cleaning around the genset and to provide a more level base. When using this method, floor strength must support the pad and the genset. The pad should be at least 6in (150mm) thick and extend beyond the genset in all directions 12in (300mm).

Weight Of The Genset

The dry weight of the entire genset is shown on the Generator Set Specification Sheet. The wet weight includes the fluids (coolant and oil). Figure 2‐2 can be used to design the foundation except in critical situations.

Figure 2‐2 Approximate Weight vs. kW Output

2‐6 General Information MN2408

Designing An Isolated Foundation

If the genset cannot be mounted directly on a floor slab, or if it is desirable to isolate it from the floor slab, then a separate foundation slab must be designed.

A massive concrete foundation is not required. Outside dimensions of the foundation should exceed the outside genset dimensions by 12in (300mm). For single genset installation, the foundation weight should be a minimum of 1.50 times the genset wet weight. For multiple genset installation, the foundation weight should be a minimum of 2.0 times the genset wet weight. Figure 2‐3 shows a method to calculate foundation thickness and the soil bearing load of the foundation and generator set. The soil load bearing capacity under the foundation must equal or exceed the load from the foundation and genset. If it does not, then a footing, as shown in Figure 2‐4 must be added to spread the load over a larger area.

Table 2‐1 shows approximate load bearing capacities for various types of soil if the actual load bearing capacity of the soil under the foundation is not known.

Caution: Check the local building codes for load bearing capacity requirements. Caution: If the soil is subject to freezing and thawing, the foundation must be extended below the frost

line. Check the local building codes.

S Reinforce the foundation with No. 8 gauge steel wire mesh placed horizontally on

6in (150mm) centers. As an alternative, use No. 6 re-bars on 12in (300mm) centers horizontally. Minimum cover over the bars should be 3in (76mm).

S Suggested concrete mixture by volume is 1 part cement, 2 parts sand, and 3 parts

aggregate. Maximum slump of 4in (100mm) and a 28-day compressive strength of 3000 psi (20,600 kPa).

S The size of the bolts holding the sub-base to the foundation should be sized to fit the

mounting holes shown on the Installation Diagram.

S Three-inch (76mm) iron pipe sleeves should be placed around the bolts in the

foundation to allow for any mislocation of the bolts after the foundation hardens. “J” or “L” type bolts are recommended for the foundation bolts.

S After the foundation is cured and the genset is located, the sleeves are filled with grout.

A. Exhaust outlets are not located upwind or near any building air intakes. B. Flexible piping section is used at engine exhaust outlet. C. Exhaust piping material is adequate for expected service. D. Exhaust piping sizing is adequate to prevent back pressure. E. Exhaust piping components are insulated as necessary to prevent operator burns and reduce pipe radiant heat losses. F. Pipe sleeves or fire proof materials are used where exhaust pipe passes through building materials as per local and state codes. G. Exhaust pipe includes rain cap or is horizontal.

The purpose of the exhaust system is to safely discharge the engine combustion products into the atmosphere outside the building. A silencer should be installed in the exhaust system to reduce noise levels. Compliance with local noise codes is always required.

Level Of Attenuation

In general, manufacturers offer three grades of silencers: industrial, residential, and critical. In most cases, these grades are comparable from make to make. However, attenuation curves for the silencer should be checked to assure the desired level of silencing is met.

System Placement

By this time, the general genset placement within the room or building has been decided. The routing of the exhaust system should be as direct as possible to the building exterior.

WARNING: Never allow the exhaust outlet to be positioned so that the exhaust gases are directed

towards any openings or air entry routes (doors, windows, vents, etc...) of an occupied building. When discharging the hot exhaust gases out of the building do not direct them towards anything that could catch fire or explode.

For aesthetic reasons, consider exhaust placement in relation to the building. Over a period of time, exhaust gas carbon deposits will tend to accumulate on any nearby wall or structure. Attention must also be given to exhaust noise in selecting placement of the exhaust system.

Multi-Engine Installations Caution: Do not connect multi-engine exhaust systems together. Each engine must have its own

exhaust system for proper operation.

Exhaust gases from an operating engine will migrate back through a non-operating engine and cause a hydraulic lock. This may interfere with starting of the second engine. The migrating gases will also tend to turn the turbos which are not being provided lubrication if the engine is not running. The use of check valves in the exhaust system are discouraged due to their tendency to “stick”.

Exhaust Manifold

There are two exhaust manifold types. Dry type which is standard and the optional water cooled. The dry type is simply exposed to the surrounding air and becomes very hot. Shields, insulating wraps, or other types of guards can be used to limit operator contact with the hot surfaces. This practice is common where engine room size is small, creating cramped conditions.

Water cooled exhaust manifolds are not available on all engine models. This type manifold has passages through which engine coolant is circulated to remove heat from the manifold surface. It also will help protect the operator from contact with the hot manifold surface. This will reduce the amount of heat that is radiated by the engine to the surrounding air by approximately 20%. In addition, this type manifold significantly increases the amount of heat the cooling system must dissipate. Marine and Mining Safety Administration (MSA) codes may require water cooled manifolds in all genset installations. If you are in doubt on your particular application, consult your Baldor Distributor.

Exhaust Gas Restriction

The maximum allowable back pressure, or system restriction, is 3 inches of mercury. If this back pressure is exceeded, the air-fuel ratio is reduced due to incomplete scavenging of the cylinders, fuel economy and power output is reduced, engine life is reduced and exhaust temperatures and smoke levels increase. Any restriction of the exhaust gas reduces horsepower. Take every precaution to reduce restriction. Proper design and installation will provide safe genset operation.

It is essential that all engine exhaust systems by designed with the least possible restriction to exhaust gas flow. This can be calculated through the use of Figure 2‐6, or in the case of simple exhaust systems, the nomograph in Figure 2‐6 may be used.

General Information 2‐9MN2408

Figure 2‐6 Exhaust System Calculations

Exhaust Piping Caution: The weight of the exhaust system must never be imposed on the turbo-charger outlet.

Damage to the turbo-charger and other components may result.

An exhaust system must withstand the vibration and thermal expansion that they are subjected to, yet supported well enough to remain independent of the engine.

The most common method of providing flexibility is with the use of bellows type flexible piping. This piping component allows lateral and linear movement of the piping system without subjecting fixed components to excessive stress. A minimum of 12 inches of flexible connection must be provided at the engine exhaust manifold to allow for thermal expansion and vibration. If the engine is to be mounted on spring type vibration isolators, increase the length to 24 inches. This component can be specified to be provided by your Baldor distributor. Flexible pipe should never be used for pipe bends or to cure misalignment problems.

Exhaust piping systems may be supported by a wide variety of methods to long as the system remains flexible, and capable of withstanding thermal expansion.

The material most commonly used for straight runs and elbows in exhaust systems is Schedule 40 black iron. If hanging weight is a problem, other materials may be used. Galvanized piping should never be used in exhaust system. Where exhaust piping passes through combustible material, exhaust thimbles must be used. See Figure 2‐7.

Figure 2‐7 Exhaust Pipe Thimble Installation

Rain Protection

Moisture entering the engine through an exhaust system can cause extensive damage. Exhaust outlets must have a rain cap or be horizontal to prevent such damage. See Figure 2‐7.

Transfer Switch

Transfer Switch Checklist

A. Locate transfer switch in a clean, dry place, near the emergency load. B. Provide a circuit breaker between the genset and the transfer switch. C. Put a flexible connection between the conduit and genset. D. Observe applicable codes in wiring-in the transfer switch and genset.

The transfer switch connects the genset to the emergency power system. The emergency power system may include several gensets and several transfer switches. Typically, the genset is wired to the emergency power system through a transfer switch as shown in Figure 2‐8.

Figure 2‐8 Typical Emergency power System Installations

Multiple Gensets can be arranged either in parallel or separately connected to dedicated emergency loads. Figure 2‐8 also shows a typical arrangement of two gensets in parallel with transfer switches for loads that have different levels of priority. A typical multiple genset installation is shown for NFPA 110 Level 1 and Level 2 emergency power circuits and a priority control to select the appropriate transfer switch.

Wattmeters should be installed on each genset so load sharing can be checked. The control system should include an automatic paralleling control. Paralleling identical gensets is not difficult, but paralleling dissimilar sets can cause load sharing problems. When designing an installation that includes the paralleling of dissimilar generators, contact your nearby Baldor Distributor.

Transfer Switch Location

The transfer switch location is important and key considerations are:

1. Locate the transfer switch as close to the emergency load as practical to avoid

2. Locate the transfer switch in a clean, dry, well ventilated location, away from excessive

genset. The flexible sections prevent vibration from damaging the conduit. All power conduits from the genset must contain all three phases.

General Information 2‐11MN2408

6. Conduit, wire, circuit protective device sizes, insulation etc. must conform to applicable local and national codes and regulations.

7. Be certain to seal around conduits that penetrate the walls of the genset room to reduce the amount of noise that is transmitted to the surrounding areas of the building and maintain site fire code rating.

Battery Starting System

This section describes the battery starting system (nominal 12 volt rating of the battery supply) for the engine, battery charger, and precautions to take if the ambient temperature is expected to be below 70 F (20C).

WARNING: If batteries are not mounted in the battery rack supplied with the genset, protect batteries

from vibration and do not locate them near a source of flame or spark. A battery presents a risk of fire and explosion because they generate hydrogen gas. Hydrogen gas is extremely explosive. Never jump start a battery, smoke in the area around the battery or cause any spark to occur in the area around the battery.

Battery Location

Locate batteries as close as possible to the genset to minimize starting circuit resistance, see Figure 2‐9. High starting circuit resistance substantially reduces starting cranking ability. Mount batteries on a level rack away from dirt and liquids. Allow space for servicing (checking water level and level of charge). Cold ambient temperature at the battery location substantially reduces the battery output.

Figure 2‐9 Battery Starting System

Battery Size

The ability to start the engine depends upon battery capacity, ambient temperature and coolant and oil temperatures. The Engine/Generator Set Data Sheet lists minimum recommended battery capacity.

Battery capacities decrease as ambient temperatures decrease so it is important to specify batteries with the appropriate CCA rating at a temperature no higher than the minimum ambient temperature for the application.

2‐12 General Information MN2408

Battery Charger

Battery Cables

An engine mounted alternator charges the batteries during engine operation. Standby gensets should include a solid state battery charger that is connected to utility power so the battery is charged continuously while the genset is not running. The battery charger should be connected to the utility power emergency circuit. The batteries on prime power gensets are charged by the engine mounted alternator, if equipped.

The output of the battery charger or the belt driven alternator must be connected directly to the battery or to the battery terminals on the starter to prevent the electronic governor from acting erratically. Make control connections to the genset control using a conduit with a flexible section at the genset to avoid damage due to genset vibrations.

The wire size (wire gauge) of the cables connecting the starter to the batteries must be large enough to ensure proper voltage at the engine starter motor during cranking. The total cranking circuit resistance includes the resistance of the cables from the starting motor to the battery and the resistance of all relays, solenoids, switches, and connections. The resistance of various sizes of cables is shown in Figure 2‐10. For purposes of calculating cranking circuit resistance to select cable size, the resistance of each connection can be taken as .00001 ohms and the resistance of each relay, solenoid, and switch can be taken as .0002 ohms. Figure 2‐10 illustrates an example of a typical cranking circuit resistance calculation.

Section 3 Receiving & Installation

Receiving & Inspection When you receive your generator, there are several things you should do immediately.

1. Observe the condition of the shipping container and report any damage immediately to the commercial carrier that delivered your system.

2. Verify that the part number of the system you received is the same as the part number listed on your purchase order.

3. If the system is to be stored for several weeks before use, be sure that it is stored in a location that conforms to published storage temperature and humidity specifications.

Lifting the Generator When lift or hoist equipment is used to lift the generator and move it to position, be careful not

to contact overhead wires or other obstacles. Be sure lift or hoist equipment has appropriate tires for the terrain to avoid becoming stuck or tipping over. If the shipping pallet is intact, use a fork lift to move the generator. If the shipping pallet has been removed, use two steel pipes through the “Lift Point” holes to lift the generator. See Figure 3‐1.

Figure 3‐1 Generator Lifting

Height

To lift the generator, always use spreader bars, chains, eyehooks and other hardware that is of sufficient strength to lift at least three times the weight of the generator.

Lift Point

Length

Width

Lift Point

Physical Location The mounting location of the system is important. It should be installed in an area that is

protected from direct harmful gases or liquids, dust, metallic particles, shock and vibration. It should be installed in an outdoor location so the exhaust fumes are vented to the atmosphere.

When the Generator is installed outdoors

The factory installed enclosure is designed to keep out undesirable weather elements while providing cooling and ventilation.

When the Generator is installed in a building it is essential to provide:

1. Adequate control and exhausting of the heated air.

2. An adequate and constant supply of incoming cooling air.

3. Adequate control and discharge of the engine's hot exhaust gases.

4. Adequate ventilation of the building when the engine shuts down.

Receiving & Installation 3‐1MN2408

WARNING: An open bottom stationary engine generator set must be installed over noncombustible

materials and shall be located such that it prevents combustible materials from accumulating under the generator set.

Several other factors should be carefully evaluated when selecting a location for installation:

1. For effective cooling and maintenance, the system should be mounted on a flat, smooth, noncombustible level surface. A concrete pad is ideal and provides a secure installation.

2. Installation should prevent water levels from reaching the generator. Drainage must be adequate to keep concrete pad free from standing water.

3. Installation should prevent obstructions by buildup of leaves, grass, sand, snow, etc. If these items pose a problem, consider building a small fence or other break to protect the unit from accumulation of debris.

4. Installation should place the generator as close as possible to the fuel supply and transfer switch.

5. At least twenty-four (24) inches clearance must be provided on all sides for air flow.

6. Access must be provided to allow the enclosure covers to be opened or removed for service and maintenance.

7. Maximum Ambient temperature is 122F (50C).

Secure the Generator

Six (eight for the GLC125) mounting bolts in the base frame secure the generator to the shipping pallet. Remove these bolts, lift the generator and remove the shipping pallet. Secure the generator to the concrete pad using

/8 anchor hardware (not provided) in the base frame mounting holes. See Figure 3‐2. Anchor bolts must be long enough to extend through the generator mounting frame.

Engine Cooling A sufficient flow of clean, cool air is required for combustion and to dissipate the heat produced

by the engine. Approximately 60% of the heat value of the fuel used is given off as heat (cooling air and exhaust).

The air that will cool the engine must be brought in from outside the building. A sufficient air-flow of rate “Cubic Feet per Minute” (CFM) will allow the incoming fresh air to cool the engine. This requires a power ventilation system of sufficient CFM to be located at the highest possible point of the building to exhaust hot air and draw in cool fresh air.

Note: The exhaust fan must not be located where it could easily become blocked by leaves,

snow, water, debris, etc.

It is recommended that the cool air intake have at least three (3) times the cross-sectional area of the power ventilation system. It is also recommended that the cool air intake be located as close as possible to the top of the generator set.

The exhaust fan must be connected to the AC power terminals of the generator set so that when the generator set starts it will provide immediate cooling air flow. The fan will operate until the generator set stops. To test the ventilation system, do the following:

Ventilation Test

1. Place a thermometer as close to the cool air intake of the engine's blower housing as you can without allowing the thermometer to touch any material surface.

2. Place another thermometer outside of the building or compartment in the open air (Keep the thermometer out of direct sunlight or any other heat sources).

3. Run the engine under maximum load for an extended period of time (at least one hour).

4. The temperature difference between the two should not exceed 15 degrees F.

Note that opening any door, window or other opening can upset the air-flow pattern and result in a significant reduction in the cooling air-flow across the generator set. This may result in overheating, fire, or explosion.

Receiving & Installation 3‐3MN2408

Hot Exhaust Gasses WARNING: Exhaust fumes/gases are extremely dangerous and can cause severe illness or death. Never

WARNING: Hot exhaust gasses must never be directed toward anything that may catch fire or explode.

It is extremely important to discharge engine exhaust gasses away from the engine and out of the building. If these gasses remain in the cylinder, poor performance or eventual engine damage may result. This condition results from excessive back-pressure, which could be caused by any one or a combination of the following conditions:

1. Exhaust pipe too long or the diameter is too small.

2. Excessive number of sharp bends in the exhaust system.

3. Obstruction in the exhaust system.

Backpressure must not exceed 20” of water column.

The direction of the discharged hot air and hot exhaust gases is important as they have the potential to create brown spots on the lawn or adjacent structures. In extreme cases this extremely hot air could cause dried grass or other debris to ignite.

Exhaust lines should be as short and straight as possible. Long pipe lengths and elbows tend to resist the flow of gases and accumulate carbon deposits. Each pipe fitting and elbow will further restrict the exhaust flow.

Guidelines for Exhaust System

1. If you are using a remote muffler it should be mounted as close to the engine as possible, since it will clog with carbon if it's operating temperature is too low.

2. If you are using a remote muffler a flexible coupling of 12” or more must be installed between the exhaust line and the manifold to absorb the engine's vibration. However, a short, solid section of pipe between 6” and 8” long should be placed between the connection of the manifold and the flexible coupling. This nipple will reduce the possibility of the hot gases burning up the flexible coupling.

3. It is extremely important that you do not allow the hot exhaust gases to re-circulate into the engine's cooling air intake.

4. Water is one by-product of combustion and is present in the exhaust pipes or muffler. This water must be kept from draining back into the engine. This can be done by slanting the horizontal section of the exhaust system piping downward slightly, away from the engine. A water trap consisting of a tee extension with a drain cock should also be provided. This water trap should be located between the flex coupling and the muffler, but as close to the engine as possible on a horizontal section of the exhaust piping.

5. It is also recommended that an exhaust rain cap be used whenever it is possible that rain could get into the system. This will help to prevent corrosion and damage to the exhaust system and engine.

6. The exhaust system is subject to the engine's vibration and it must therefore be solidly secured to reduce mechanical stress and the potential for breakage.

7. The engine's exhaust system is the hottest component of the installation and extreme care and considerations must be given to it.

3‐4 Receiving & Installation MN2408

8. As much of the exhaust piping as possible should be located near the power ventilation exhaust. This will reduce the radiant exhaust heat inside the building.

9. Keep all fuel and its associated piping away from all components of the engine exhaust system.

10. After the exhaust system is installed it should be inspected on a regular basis to assure there are no toxic exhaust gas leaks. In some areas this inspection may be provided by your local public service.

11. A carbon monoxide tester may be installed to detect the presence of the deadly gas during times when you are in the building with the engine running (during testing or maintenance).

WARNING: Never allow the exhaust outlet to be positioned so that the exhaust gases are directed

WARNING: Exhaust fumes/gases are extremely dangerous and can cause severe illness or death. Never

Installation The generator is completely assembled, tested and adjusted at the factory before it is shipped to

you. The procedures presented in this manual are suggestions and it is the responsibility of the Owner/Operator to arrange for these procedures to be performed by licensed contractors according to all applicable codes including local codes for your Municipality/City/County and State. External connections required at the time of installation are:

1. Fuel System.

2. Electrical Connections - power wiring (optional transfer switch) and control wiring.

3. Battery (not included).

4. Ground Connection. After installation, the post installation checks must be performed prior to starting the engine. After these checks have been performed and the system operation is verified to be good, refer to

Section 5 Maintenance for periodic checks that must be performed at scheduled intervals to ensure continued operation with minimal problems.

Fuel Connections

Fuel selection is Natural Gas or LPV (Liquid Propane Vapor). If natural gas supply is used, follow the “Natural Gas Connections” procedure. If LPV supply is used, follow the “LP Vapor Connections” procedure. Table 3‐4 defines the flow rate required for each fuel type.

General Considerations

1. A generator set needs the engine to deliver 2 hp of energy to the alternator for every

1000 watts of electric output power (example: an 8000 watt generator needs the engine to deliver 16 hp of energy to the generator end).

2. An engine needs 10,000 BTU's of fuel energy per horsepower of engine power to

provide a sufficient supply of fuel (example: a 16 Hp engine needs 160,000 BTU's of fuel energy for it to work properly). This fuel must be supplied to the regulator on the generator set at a pressure of 6 oz (11 inches of water column). To achieve this 6 oz. pressure in a L.P. System, you will normally have to reduce the tank pressure by means of a primary regulator or a regulator system of 2 or more regulators.

3. There are 2,516 BTU's in one cubic foot of Propane (LP Fuel).

There are 1,096 BTU's in one cubic foot of Natural Gas.

4. There are 36.39 cubic feet in one gallon of Propane.

There are 57.75 cubic feet in one gallon of Natural Gas.

5. There are 8.58 cubic feet per pound of Propane.

There are 23.56 cubic feet per pound of Natural Gas.

6. When installing the piping for the gaseous fuel supply please refer to the pipe chart in

Tables 3‐5 and 3‐6 to be sure you are using piping of significantly large size to deliver the necessary amount of fuel.

7. If copper tubing is used, it should be “K” or “L” having a minimum wall thickness of

0.032 inches. Black Iron Pipe is recommended but follow building codes for your area.

Battery Charger Considerations

1. Mount the battery charger on the generator or as close to the generator as possible.

2. If you mount the battery charger inside the building, mount it near the main breaker box or disconnect box.

3. If you mount the battery charger outside, you must protect it from the environment and the elements.

4. Do not mount the battery charger where flammable liquids or vapors are present.

General Wiring Considerations

1. When routing the interface wiring, do not route it up against anything that could cut or chafe the wiring. do not route the wire up against any hot or potentially hot object.

2. Make sure that all the electrical components (generator set, transfer switch, battery charger, etc.) share a common hard wired ground.

3. Check with your local building inspector to determine what you must do to comply with the local regulations for grounding of this type of permanent installation.

3‐12 Receiving & Installation MN2408

Battery Connections The generator may be shipped with no battery installed.

Procedure: The correct type battery must be installed in the battery compartment provided, see Table 3‐7.

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

Post Installation Checks

When the initial installation is complete, these checks must be performed before starting the engine. These checks are not required before each start, only after the initial installation.

1. Generators that have been in transit or storage for long periods may be subjected to extreme temperature and moisture changes. This can cause excessive condensation, and the generator windings should be thoroughly dried before bringing the generator up to full nameplate voltage. If this precaution is not taken, serious damage to the generator can result.

Caution: Do not apply high voltage to windings (do not start the generator) in a moisture-saturated

condition. Moisture can cause insulation breakdown, making it necessary to return the generator for repair.

Note: These precautions are especially necessary in locations such as seaboard installations

and other high humidity areas. Some installations will be in atmospheres that are much more corrosive than others.

2. Verify that the transfer switch is in Utility Power mode. No power must be present at the generator or transfer switch connections. Verify with a voltmeter.

3. Verify that the engine starting battery is disconnected so accidental starting is not possible.

4. Verify that the generator is securely mounted and anchored to its cement pad.

5. Verify that proper clearance exists on all sides and top of enclosure.

6. Verify that generator power is properly connected to the transfer switch.

7. Verify that generator and transfer switch are properly grounded.

8. Assure that generator is a safe distance from any flammable or combustible material.

9. Verify that the generator and transfer switch load are voltage compatible.

10. Verify that no load is connected to the circuit breaker and/or transfer switch.

11. Inspect the engine and generator and verify that there are no loose wires or components. Tighten if necessary.

12. Verify that the ground conductor is of correct wire size and properly connected.

13. Verify engine oil level is full. Refer to engine manual if necessary.

14. Verify engine coolant level is full. Refer to engine manual if necessary.

15. Verify exhaust system to assure it is in properly connected and pointing away from combustible materials.

16. Verify that the Master Control Switch is still in the “Stop” position. Connect the engine starting battery to the starter. Verify it is installed correctly.

17. Verify the fuel source is ON and the pressure and flow rate are correct.

18. Remove all tools, rags, etc. from inside the generator enclosure. Close all enclosure doors and be sure no hands are inside the generator enclosure when it starts.

19. Verify all loads are disconnected.

20. Start the generator. (Refer to Section 4 Operation for details).

21. The engine should begin to crank and start when the fuel moves through the pipe to the carburetor. If the engine fails to start, refer to Section 5 Troubleshooting.

Post Installation Checks

Continued

22. With the engine running, several checks must be made: a. Verify there are no fuel leaks. If a fuel leak is detected, stop the engine

immediately (move the Master Control Switch to the “Stop” position) and repair the leak before proceeding.

b. Verify there are no coolant or oil leaks. If a leak is detected, stop the engine

immediately and repair the leak before proceeding.

c. Verify that operation is smooth. If belt squeals, vibrations or other sources of

noise exist, stop the engine immediately and repair before proceeding.

d. Verify that the correct voltage exists (line-to-line and line-to-neutral) at the

generator and at the transfer switch.

e. Minor adjustment of the output voltage is made using the “Voltage Adjust”

potentiometer on the control panel.

WARNING: Engine coolant is under pressure and is near the boiling point of water when engine is hot.

Do not open the coolant system until the engine has completely cooled. Hot coolant can cause severe burns and other injuries. When engine is cool, coolant level can be checked.

23. After the operation checks are made, stop the engine (move the Master Control Switch to the “Stop” position) and wait at least 2 hours for the engine to cool. When the engine is cool, check engine oil and coolant levels as instructed in the engine operation manual.

24. Close all enclosure covers. The post installation checks are now complete.

The Operator Control Panel is shown in Figure 4‐13.

WARNING: Never connect this generator to any buildings electrical system unless a licensed electrician

has installed an approved transfer switch. The National Electrical Code (NEC) requires that connection of a generator to any electrical circuit normally powered by means of an electric utility must be connected by means of approved transfer switch equipment so as to isolate the electrical circuit from the utility distribution system when the generator is operating. Failure to isolate the electrical circuits by such means may result in injury or death to utility power workers due to backfeed of electrical energy onto the utility lines.

if one of the programmable output contacts is configured for “ATS Test” and the remote transfer switch has remote testing circuitry. When pushed, a signal is issued to the remote transfer switch to permit an automatic engine start and load transfer. Once initiated, the engine will receive a start signal from the transfer switch and upon the generator reaching nominal voltage and frequency levels, a load transfer will be initiated. The generator set will remain running at load until a different operating mode is selected or the generator set develops an alarm or shutdown fault condition.

Operating Procedures The engine-generator controller is designed to start and stop an engine from either a

local (“Manual”) or remote (“Automatic”) modes. When a start command is issued, the controller issues a run and crank output signal. The controller then monitors engine speed and when crank disconnect speed is reached, the crank signal is terminated. While the engine accelerates to normal speed, the controller continuously monitors the engines speed signal. Should the engine speed exceed the maximum predetermined setpoint, the overspeed shutdown fault circuit will activate, terminating the run signal.

In addition to overspeed shutdown, the engine controller also monitors many other engine protection circuits and should they be activated, the engine will be stopped and/or alarm initiated. The engine will automatically stop for any shutdown condition, or when the remote and/or local start signal is removed. The engine controller operation includes time delay circuits for normal operating conditions such as start delays, cool down and cranking periods.

Manual Start/Stop

To manually Start the Gen-Set, push the “RUN” push-button. The following happens:

1. When the “RUN” push-button is pressed, an ENGINE START DELAY timer is initiated. (The start sequence will not be initiated if any shutdown fault condition is present.)

2. When the engine start delay time expires, an engine RUN and CRANK output signal will be initiated. (The RUN output may be programmed to only energize when a start signal is initiated and an engine speed signal is detected.)

3. When the engine starts and begins to accelerate to nominal speed, the controllers speed sensor will terminate the CRANK output when engine speed reaches approximately 20% speed (i.e. CRANK DISCONNECT speed setpoint). Immediately upon reaching crank disconnect speed, the controller will initiate the BYPASS DELAY time delay function. After the BYPASS DELAY time period (typically 10 seconds) all fault circuits programmed as BYPASS DELAY=YES are active. (All fault circuits programmed as BYPASS DELAY=NO are continuously armed irrespective of any operation sequence.)

To manually Stop the Gen-Set, push the “OFF” push-button. The controllers RUN output will be immediately terminated which will initiate the engine stop sequence.

Automatic Start/Stop

To setup the generator for automatic operation, pressing the “AUTO” push-button. The following happens:

1. The engine will automatically start upon activation of the remote start contact input. The remote device initiates a start sequence upon contact closure.

2. When the remote start signal is activated, the engine will start as per the sequence of operation described for the manual start sequence.

3. The automatic stop sequence will be initiated by removal of the remote start signal.

4. When the start signal is removed, a cool down delay function will be initiated.

4‐14 Operation MN2408

5. When the cool down time delay period expires (typically 5 minutes), the controllers RUN output will be immediately terminated which will initiate the engine to stop.

Automatic Fault Shutdown

When a fault circuit is programmed as a SHUTDOWN, the engine will immediately stop when the fault is activated. A specific shutdown fault can be programmed with a definite time transient delay period that must expire before the shutdown is activated. The stop sequence will cause the controllers RUN output to be immediately terminated which will cause the engine to stop. This will prevent subsequent operation of the generator set. The Run/Stop/Auto selector switch on the operator control panel must be momentarily placed in the “Stop” position to reset the fault.

Automatic Mains Failure (AMF)

Figure 4‐14 Auto Mains Failure (AMF) Connections

Transfer Switch

Operation 4‐15MN2408

When the controller is applied in an Auto Mains Failure (AMF) application with a transfer switch, it must be wired as shown in Figure 4‐14. Programmable output #3 must be selected for Utility Ready To Load and programmable output #4 must be selected for Gen Ready To Load. After the controller is programmed, the AMF sequence of operation will be as follows:

Utility Normal Condition:

1. Remote Start input signal (terminals 16 & 17) is not activated (i.e. normal).

2. Utility Ready To Load output is energized (i.e. signal to transfer switch to transfer to utility power).

3. Generator Ready To Load output is de-energized.

Utility Power Failure Conditions:

1. Remote Start input signal is activated (i.e. remote start contact closes when utility power fails, as sensed by utility voltage sensor).

2. Engine starts after the Engine Start Delay timer (Utility Ready To Load output stays energized).

3. After the engine has started and the generator output rises above the programmed voltage and frequency limits, a Warm-Up timer is initiated.

4. After the Warm-Up timer expires the Utility Ready to Load output de-energizes and the NEUTRAL Delay timer is initiated.

5. After the NEUTRAL DELAY timer expires the Gen Ready to Load output energizes to signal the transfer switch to transfer to the generator supply. Note: The neutral delay function is only operative with an electrically-held type transfer switch mechanism (ie. electrical contactor type).

Utility Power Restored:

1. Remote Start input signal is removed and the Return Delay timer is initiated (i.e. Utility Voltage returns to normal and the Utility voltage sensor contact opens).

2. After the Return Delay timer expires, the Generator Ready to Load output de-energizes and the Neutral Delay timer is initiated.

3. After the Neutral Delay timer expires the Utility Ready to Load output energizes to signal the transfer switch to transfer to the utility supply. Note: If the generator has a shutdown during the Return or Neutral Delay periods, the timers are bypassed, and the Utility Ready to Load output immediately energizes.

4. The generator Cool down Timer starts after the Return Delay timer.

5. The generator stops after the Cool down Timer.

Load Test Push-button Operation

1. When the Load Test pushbutton is pressed, the logic will internally simulate receiving a remote start input.

2. Engine starts after the Engine Start delay timer.

3. After the engine has started and the generator output rises above the programmed voltage and frequency limits, a Warm-Up timer is initiated.

4. After the Warm-Up timer expires the Utility Ready to Load output de-energizes and the Neutral Delay timer is initiated.

5. After the Neutral Timer expires the Gen Ready To Load output energizes to signal the transfer switch to transfer to the generator supply.

Note: If a generator shutdown occurs during a Load Test Operation, the Load Test mode will be

de-activated.

When Auto Mode is restored (after Load Test Operation) the following occurs:

1. Simulated Remote Start input signal is removed.

2. Gen Ready To Load output de-energizes, and Neutral Delay timer is initiated.

3. After the Neutral Delay timer expires The Utility Ready To Load output energizes to signal the transfer switch to transfer to the utility supply.

4. The generator Cool down timer starts timing following the transfer to the utility supply.

5. The generator stops after the Cool down timer.

4‐16 Operation MN2408

No Load Test

To allow a timed No Load Test of the engine/generator set while using the AMF control application, a digital input contact from an external timer must be programmed for NO LOAD Test The sequence of operation for a No Load Test condition is as follows:

1. With the utility supply normal and the generator stopped, a no load test sequence may be initiated by closing an external exercise timer contact to the programmed digital input for No Load Test.

2. After the external exercise timer contact closes, the engine will start and come-up to normal operating speed and voltage. The controller will issue an alarm of a No Load Test condition. The connected transfer switch will remain on the utility and the generator will not transfer on load. Note: should the utility supply fail, the generator will automatically transfer on load.

3. The engine will continue to run as long as the external exercise timer contact remains closed.

4. After the external exercise timer contact opens, the engine will continue to run for its cool down time as programmed, then it will automatically stop.

Standard Faults When a fault occurs, information about the fault is displayed. The engine controller has many

analog and digital inputs for monitoring and control operations. Three types of faults are used:

1. Internal Faults are derived from a combination of digital and analog inputs.

2. Digital Input Faults are initiated from external contact inputs.

3. Analog Input Faults are initiated from external analog signal inputs.

Figure 4‐15 shows how the controller inputs and outputs are organized. A description of each is provided.

application). The Neutral Delay timer is used when transferring between the available power sources. When transferring from the utility supply to the generator supply, the Neutral Delay timer will start when the Utility Ready To Load output de-energizes. When the Neutral Delay time period expires, the Generator Ready To Load output is energized. The purpose of the Neutral Delay timer is to prevent out of phase transfers, which may be caused by a fast transfer and the two sources of supply are out of synchronism. The Neutral Delay timer ensures the load voltages decay before the transfer is initiated. Set to the desired time in seconds. The Neutral Delay timer is typically set for 3 seconds.

Note: The Neutral Delay feature is only effective when an electrically held “contactor-type” transfer switch is connected.

Contact Baldor for further application information on use with other types of transfer switch mechanisms.

Return Delay is initiated when the remote start signal is removed (signaling utility power is available). After the Return Delay timer expires, the Generator Ready To Load output is removed, and the Utility Ready To Load output energizes to signal transfer the load back to the utility supply. The purpose of the Return Delay timer is to ensure that the utility power has returned to a steady state for the selected time period before the load is transferred back to the utility supply. The Return Delay timer is typically set for 120 seconds.

Displays the calibration correction factor number (0-255) used to obtain the correct voltage reading. Note: To correctly calibrate any of the voltage sensors, the ZERO function must be calibrated before the SPAN function. Displays the actual voltage measurement that will be the same value as shown on the MEC 2 display menus for generator supply. This voltage reading may be calibrated higher or lower by changing the correction factor number.

Voltage Calibration Procedure

Note: Zero Calibration must be completed before Span Calibration.

Zero Calibration Connect an external AC voltmeter of adequate voltage range and accuracy to the MEC 2 controller terminals associated

with the voltage phases to be calibrated. With the generator stopped, confirm there is Zero volts on the phases to be calibrated. In the programming mode, scroll to each of the desired generator supply voltage phases (i.e. phase to phase or phase to neutral) with the ZERO function selected. Use the INCREMENT or DECREMENT push-buttons to adjust the correction factor number to obtain zero volts on the right hand side of the display as confirmed with the external voltmeter. The factory default correction factor is 127. Increasing this will raise the displayed value, conversely decreasing this value will decrease the displayed value. Note: Adjusting the ZERO function with voltage applied will result in non-linear voltage readings. With the correct voltage displayed, press the ENTER push-button to accept the correction factor number. Record the correction factor number on the programming sheet for future reference. Repeat this procedure for all remaining phases.

Use the INCREMENT or DECREMENT push-buttons to adjust the correction factor number while observing the displayed voltage level. Adjust the correction factor number to obtain an identical voltage reading as measured with the external AC voltmeter. With the correct voltage displayed, press the ENTER push-button to accept the correction factor number. Record the correction factor number on the programming sheet for future reference.

further adjustment, the span calibration point must also be re-calibrated.

Current Sensing Calibration To accurately calibrate the current sensors, an external test AC ammeter and current clamp

is required, with an accuracy of 0.5% or better.

Displays the generator load current (phase A, B or C) to be calibrated. Displays the type of calibration function, either ZERO or SPAN. Displays the calibration correction factor number (0-255) used to obtain the correct current reading. Note: To correctly calibrate any of the current sensors, the ZERO function must be calibrated before the SPAN function. Displays the actual current measurement that will be the same value as shown on the MEC 2 display menus for

generator supply. This current reading may be calibrated higher or lower by changing the correction factor number.

Zero Calibration Connect an external AC ammeter with current clamp of adequate current range to the controller terminals associated with

the current phases to be calibrated. With the generator stopped, confirm there is “0” current on the phases to be calibrated. In the programming mode, scroll to each of the desired generator supply current phases with the ZERO function selected. Use the INCREMENT or DECREMENT push-buttons to adjust the correction factor number while observing the displayed current level. Adjust the correction factor until “0” amps is displayed. With the correct current displayed, press the ENTER push-button to accept the correction factor number. Record the correction factor number on the programming sheet for future reference. Repeat for each phase.

Span Calibration Apply 50%-100% load to the generator set. It is recommended to load the generator set to 100% rated load for

calibration purposes to obtain good accuracy throughout the full span of operation. Do not exceed the current rating of the CT. Non-linear output of the CT will result when the secondary current exceeds 5 amps and will similarly effect the displayed values. In the programming mode, scroll to the desired generator supply current phases with the SPAN function selected. Connect an external AC ammeter and current clamp of adequate current range to the controller terminals associated with the current phases to be calibrated. Use the INCREMENT or DECREMENT push-buttons to adjust the correction factor number while observing the displayed current value. Adjust the correction factor number to obtain an identical current reading as measured with the external AC ammeter. With the correct current displayed, press the ENTER push-button to accept the correction factor number. Record the correction factor number on the programming sheet for future reference. Repeat for each phase.

Note: When the span calibration setting is complete, re-confirm the zero calibration points. If the zero calibration setpoint needs

further adjustment, the span calibration point must also be re-calibrated.

Section 5 Troubleshooting and Maintenance

Maintenance This manual contains only very minimal engine maintenance instructions. Refer to the engine

manufacturer's owner's manual for specific engine maintenance instructions for your generator set. Any maintenance instructions or recommendations in the engine owner's manual take precedence over any of the following general recommendations.

General:

1. Inspect the fuel system for leaks. Replace all defective components immediately.

2. Inspect and replace any fuel line that shows signs of deterioration.

3. Inspect all the fuel clamps to ensure they are tight.

4. Inspect and clean the battery posts and the associated battery cable terminals.

5. Inspect the external wire cables and connectors used with the generator set for cuts, fraying, or loose connections. Repair or replace any problems prior to using the unit.

Engine:

1. Clean and/or replace any fuel, oil, and/or air filters per the engine manufacturers' guidelines.

2. Check oil level regularly; at least every 5 to 8 operating hours. Maintain the proper oil level.

3. Change the oil as is recommended in the engine manufacturer's owner's manual.

4. Replace the spark plug(s) as is recommended by the engine manufacturer.

5. Clean the cooling fins on the engine to keep the engine's heat dissipation potential at it's maximum.

6. Inspect and clean all governor and carburetor linkages so they operate properly.

7. Inspect the recoil starting rope for any damage and replace it if necessary (if applicable).

8. Clean the trash screen around the recoil starter or other cooling air intake.

Alternator:

This generator set must be run at its proper speed to obtain the correct electrical power at its output. All engines have a tendency to slow down when a load is applied to it. The engine governor is designed to hold the operating speed as nearly constant as possible. When the electrical load is increased, the engine is more heavily loaded and engine speed drops slightly. This slight decrease in engine speed results in a slight decrease in generator voltage and frequency output. This voltage and frequency variation has no appreciable effect in the operation of motors, lights, and most appliances and tools. However, timing devices and clocks will not keep perfect time when used on this generator.

( also called Generator End)

1. Clean the generator set and remove any and all dust, dirt, or other foreign material.

2. Inspect and clean the cooling air intake and exhaust louvers of the generator end. Make sure they are clean. Remove dirt or any buildup that may restrict the cooling air flow.

3. Clean the generator set and its components with a damp cloth or sponge. Never use a water hose or pressure washer as this may damage electrical components.

4. Inspect and replace any control panel components that are broken or not working properly (receptacles, circuit breakers, switches, etc.)

Troubleshooting and Maintenance 5‐1MN2408

Problems and Solutions

Some of the more common problems are listed in Table 5‐1. This information is intended to be a check or verification that simple causes can be located and fixed. It is not an exhaustive “how to” for all types of problems. Procedures that require in depth knowledge or skills (like flashing the field) should be referred to a qualified generator service center.

Table 5‐1 General Troubleshooting Guide

Problem Possible Cause Remedy

Engine cranks but will not start

Engine will not crank (electric start) Dead battery.

Engine starts but will not run smoothly Fuel or ignition problem Refer to engine manual.

Engine overheats Excessive load

No output voltage Ciruit Breaker tripped or failed.

Output voltage varies Irregular speed (fixed speed mode)

Low output voltage Low engine speed

High output voltage Excessive speed (fixed speed mode) Check engine for malfunction. Verify engine RPM.

Electrical shock when frame is touched Static charge.

Mechanical noise Internal failure of Alternator

No fuel. Low Oil Level Restricted air flow. No spark.

No engine speed during crank

Emergency Stop LED is ON

Debris or dirt buildup on engine

Internal failure of Alternator

Fluctuating speed (fixed speed mode)

Loose terminal or load connections

Excessive load High resistance connections -

connections will be warm or hot Internal failure of Alternator Low power factor

Grounded armature or field coil.

Loose or misaligned coupling

Check that fuel valves are ON. Check fuel level in fuel tank. Low Oil Pressure Sutdown activated. Replensih oil to full. Check/replace air filter. Check/replace spark plug(s). Check that engine switch is in Start position.

The magnetic pickup must be correctly adjusted and operating. Remove battery and trickle charge or replace with new battery.

Never Jump Start. Reset controller after an Emergency Stop.

Remove one or more electrical loads. Remove debris. Clean engine surfaces to allow cooling.

Reset circuit breaker or replace if required. Return to factory for repair.

Check engine for malfunction or load for fluctuation Stabilize load. The addition of a lamp load (resistance load) may

compensate partially for load changes caused by intermittent motor operation. Do not overload.

Verify all connections and terminal tighness.

Verify engine RPM. Check engine for malfunction or system for overload. Reduce load.

Verify all connections and terminal tighness.

Return to factory for repair. Reduce inductive (motor) load. Some AC motors use about the

same current regardless of load. Do not use motors of greater horsepower rating than is necessary to move the mechanical load.

Ground generator frame at local reference ground (see Section 3). Return to factory for repair

Return to factory for repair Tighten; align coupling and alternator shaft to engine shaft.

Keypad not connected to controller Verify the interconnecting ribbon cable between the lexan faceplate

Check that there are no wiring errors/short circuits connected to the controller.

The MEC 20 contains an electronic fuse that trips when an overload condition exists and does not reset until the supply voltage is removed and reapplied after the overload condition is corrected.

Check that the controller's microprocessor is running by observing a red flashing “watchdog” LED on the rear of the PCB. Replace controller if failed.

Check DC supply voltage at terminals B+ & B- (10-30VDC). Adjust LCD contrast potentiometer (R115) on rear of PCB for best

display.

Verify the engine is at a complete stop before trying to reset. Set the controller to the OFF mode before trying to reset.

All shutdown faults must be reset (red shutdown LED must be off). Engine speed signal must be detected (speed signal green LED on)

during cranking if the “run-output fail safe” feature is enabled. Verify correct magnetic pickup signal at cranking (2.0VAC min. during cranking).

Check that the RUN output LED (on the rear of the PCB) is on. If yes, verify relay contact operation on terminals #18 & #19. Replace controller if failed.

Verify the controller programmed values are correct for the number of flywheel teeth, nominal RPM, and overspeed setpoint percentage. Replace controller if failed.

Verify the controller programmed values are correct for the voltage sensing PT ratio and/or current sensing CT ratio.

Verify that the battery supply DC negative conductor is properly grounded to the engine block (i.e. to a common ground point).

Verify that the controller's analog input is properly calibrated. Verify the voltage sensing wiring connection to the MEC 20 matches

power distribution type. Note: standard direct voltage connection requires that the generators neutral is solidly grounded.

Verify that the controller's analog input is properly calibrated. Verify engine sensors.

Note: engine sensors must be factory supplied units only. Verify that the battery supply DC negative conductor is properly

grounded to the engine block (i.e. to a common ground point).

Verify the sending units wiring to controller terminals #37 & #38 (i.e. wiring is not open or shorted).

Verify the engine mounted senders have correct resistance values for corresponding input temperature or pressure.

Verify calibration.
