radiator cap while engine is hot or has been running more than a few minute.
3. Liquid petroleum gas (LPG)
When using LPG as fuel, make sure the pressure of LPG is normal, or the generator
unit will not start or could have an electrical which can cause damage to electrical
appliances and equipment.
DO NOT remove or loosen gas lines while running. Check for gas leaks prior to
starting the generator. Verify consistent line pressure for leaks by applying a soap and
water mixture applied to the line connections and joints or by using an in-line pressure
gauge. A leak may be indicated if the soap and water mixture forms bubbles around the
joints or connections. If testing by using an in-line pressure gauge. Once the gas line is
fully pressurized, check the pressure shown on the gauge, ten shut off the gas supply to
the line. If the line pressure decreases than a leak may be present. For testing
purposes, observe the joints, connections, or pressure gauge for at least one minute.
If a leak is detected or suspected, fix the leak prior to starting the generator.
The correct LPG pressure range for this generator is 2.0kpa—3.5kpa (0.29–
0.52psi)

3. Exhaust color.
As long as the generator engine is running within the rated output range,
 The exhaust will be colorless.
 If the exhaust is dark grey or black when after running for 60 seconds or more, this is
an indication of a problem. Shut the engine down until the problem is corrected.
4. Other problems requiring shutting down the generator
You should shut down the engine if the following circumstances happen.
 The engine speed is hunting ( inconsistently speeding up and down)
 An abnormal noise is heard coming from the generator.
 The engine exhaust suddenly turns dark grey or black.
 The fault indicating light is illuminated.
VI. Shutting down the generator
Should a need occur to shut down the generator, shut down the electrical output first
by turning the circuit breaker to the “OFF” position and depress the reset key. This will
automatically shut the engine and generator down.
If engine coolant temperature is too high, DO NOT immediately turn off the engine
or the fuel switch to stop generator. Doing this could cause the coolant lines to burst do
to and increase in engine coolant temperature and line pressure.
VII. Generator Fuel Switch
After starting the generator, the engines and its exhaust muffler will become very hot.
During maintenance and inspection of the generator, avoid leaning against or touching
these until they have substantially cooled.
DO NOT switch the fuel types while the generator is running!
If you need to switch fuel types, closely follow the instructions below:

1. Switching fuel types between LPG and NG
● When switching between LPG and NG, be aware that there may be different LPG or
NG pressures between suppliers. If the pressure of LPG or NG is too high, you will
need to install a pressure regulator valve to reduce the external pipeline to meet the
generator requirements. The correct gas pressure for this generator is 2.0—3.5Kpa
(0.29– 0.52psi) for LPG, and 1.7—3.5Kpa (0.25 psi-0.51psi) for NG.
● Depending on the type of fuel you use, turn the gas inlet valve to the correct position,
see below photos for proper valve position:
NG
LPG
● Securely connect the gas inlet line to the gas inlet on the generator and tightly
secure using proper clamps to avoid fule gas leakage.
GAS INLET
● Check for gas leaks before starting generator.
● Check to make sure the gas inlet valve is in the correct position for the gas fuel
type selected.

Ⅳ. Speed Regulating System
The speed regulating system is an important part which can affect the battery,
frequency, and the generators constant running speeds. It is one of the important
systems that measure the quality of the generator.
In order to control the steady frequency of the generator, a proprietary electronic
speed control system has been adopted to reduce the reaction time needed to speed up
and produce the electrical power output required and insure it is of very high quality.
This helps protect sensitive electronic equipment and appliances from burning out or
damage.
This proprietary electronic speed control systems primary function is to adjust the
engine speed. Speed sensors detect the speed of the engines flywheel and transfer it to
the electronic controller. As changes are detected, the controller immediately adjusts
the engines speed and throttle valve which controls the air flow to the engine. If the
engine speed is too high, the electronic speed regulator reduces the engine speed
immediately and the gas flow intake. The engine instantly reduces speed due the
decrease gas intake. Just the opposite occurs if the engine speed is too slow.
By continuously monitoring the engines performance and requirements, the
proprietary electronic speed control system can ensure that the engines speed is in
dynamic balance of within a tolerance of 1% deviation. The electronic speed control
system can detect engine performance needs and fluctuations almost instantaneously
and completely avoid engine damage in most circumstances.

Engine Low speed. high speed, and load stability are closely correlated to one
another. When tuning the engine, all three must be noted. Optimizing the system’s
stability under each of the three states will achieve the best engine performance.
Ⅴ. Gas Fuel System
The gas fuel system can adjust the gas intake made available to the engine for
combustion. By creating negative pressure, the gas fuel can be sucked into the venturi
and mix with the incoming air.
29
USER MANUAL FOR BEEM OUTDOORS, LLC. 20KW
SILENT STANDBY GENERATOR SET
1. Gas inlet: Connects the external fuel lines to the generator. The outer diameter is
¾” (19mm), and the internal diameter is 5/8” (15mm).
2. Gas filter: Will filter most impurities from the gas. The internal filtering element
helps to prevent carbon deposits from building up inside the fuel lines, engine, and
exhaust lines.
3. Solenoid valve: Included is an electrically controlled double solenoid valve and is
operated by the electronic control system. It uses a 12V DC drive solenoid winding coil
to produce a magnetic field which adjusts the sealed diaphragm upward or downward to
allow the gas to flow as needed.
4. Gas Pressure valve: Adjust the inlet gas using the negative pressure created by
the engine. This pressure is automatically reduced when absorbed by the engine. The
diaphragm will adjust upward or downward as needed. The position of the diaphragm
adjusts automatically applying to correct amount of pressure to the available gas flow as
needed to force the gas feed to insure proper engine performance.
5、Switch valve: Allows selection of natural gas (NG) or liquid propane gas (LPG)
gas as fuel. The gas line diameters have been pre-determined to optimize the gas flow.
The flow of gas and operating performance of the gas system has been tested before
leaving the factory. Adjustment of this system or lines by a non-professional may alter
the flow of gas causing the engine not to start or run properly.
Ⅵ. Control System
The intelligent control system is the core of the generator control system. The
intelligent control system has an integrated and visual operational panel which includes
the ability to set and monitor various system functions. It can also display different
measured parameters, control parameters, and the generator operating status.
Sensors are located on the engine and generator to monitor liquid coolant
temperatures, oil temperatures, engine operating conditions, generator operating
condition, the quality of the electrical power supply, etc… It has the ability to switch to a
self-protection mode should abnormal operations be detected. A remote operation port is
available allowing trained professionals to set unique operating requirements.
Refer to the control panel user manual and the wiring diagram for a more detailed
description of the control system.

Chapter Five:
Maintenance of Generator
Regular maintenance is an important procedure in maintaining regular use of the
generator. To enable the generator to remain in proper working condition, be sure to
maintain the generator according to the maintenance specifications.
The following generator maintenance specifications are required procedures to help
insure your generator remains in good operating condition. If the working or environment
conditions where the generator is located are extreme, (such as excessive dust, heat,
humidity, etc.) the maintenance period should be shortened to accommodate conditions.
When maintain the generator, operate in strict accordance with the following
requirements. Improper operation can cause irreparable generator failure.
Ⅰ. First Starting & Running New Engine
The life of the engine is greatly related with the first use. The first starting and running
the new engine should be done without any generator electrical load for one hour. After
this one hour break in period, re-check all fluid and oil levels and refill as needed. Once
completed, your new generator is ready for use.
Ⅱ. Fuel System Maintenance
The generator set is bi-fuel. It can run on natural gas (NG) or liquid propane gas
(LPG) only. In regards the generators maintenance, maintenance will is different
according to the fuel select.
Gas fuel is highly flammable and an explosive material. Never use or have an open
flame within 10 feet of the generator unit or the incoming fuel lines!
1. When using LPG as fuel:
● Before beginning operation, check all fuel line connections and tighten any that are
lose. Use a mixture of soap and water to check for gas leaks at all fuel line joints and
connections. Tighten and stop any leads before starting the engine.
● If the LPG fuel tank needs to be replaced, first close the tank valve and turn off the
engine power.
● After replacing the LPG fuel tank, re-open the tank valve and check again for any
possible leaks at the fuel line joints and connections. Fix any leaks before re-starting
the engine.
● Once per year, check the pressure valve to verify that the solenoid valve sealing pad is

SILENT STANDBY GENERATOR SET
not deformed. Before inspecting and dismantling, close the fuel line inlet valve to the
engine. Then start the engine one more time to use up any remaining gas in the fuel
line before removing the solenoid valve. Without using up the excess gas in the lines,
high-pressure in the lines could cause work an unsafe working condition.
● Reducing excess pressure is an important component of the gas supply system. Pay
particular attention to its operation. If there are any leaks, correct these problems to
maximize fuel efficiency and reduce the risk of fire or explosions. Periodically remove
the pollution discharge plug on the pressure reducer. Drain off any excess oil and
condensation to increase the flow of fuel and increase the engines performance.
2. When using NG as fuel:
● Before beginning operation, check all fuel line connections and tighten any that are
lose. Use a mixture of soap and water to check for gas leaks at all fuel line joints and
connections. Tighten and stop any leads before starting the engine.
● Once per year, check the pressure valve to verify that the solenoid valve sealing pad is
not deformed. Before inspecting and dismantling, close the fuel line inlet valve to the
engine. Then start the engine one more time to use up any remaining gas in the fuel
line before removing the solenoid valve. Without using up the excess gas in the lines,

IV. Troubleshooting
1.) Poor electrical connections
● Battery voltage, verify the voltage is correct
● Low fuel gas supply, verify gas cylinder solenoid valve is open
● Incoming solenoid valve at generator open
● High voltage normal (check spark plug)
● Speed sensor signal
● Observe exhaust gas (smell, color, sound)
● Replace the faulty parts with the new.
● If the fault has stopped, replace the faulty parts, then re-start the engine and
observe to verify the problem exist again.
● If the fault re-appears, then it is verified that the parts were damaged, replace the
damaged parts with new.
Ⅴ. Other problem conditions and remedies
Engine will not start:
Generator will not start normally. Follow these steps:
1. Visually check for loose wires or electrical cables?
● Check engine oil level, high or low?
● Check engine coolant, high or low?
● While attempting to start, is the emergency stop switch button open or closed,
(press down to close, press up to open)
● Check if main inlet gas valve is open or closed? Is there gas flow through when
43

SILENT STANDBY GENERATOR SET
open?
● Make sure the battery has 12.4 volts or higher?
● Is the power indicator light on or off?
2). Measurement verifications:
● Fuel gas pressure flow pressure is too high: Turn the regulator adjustment screw
to adjust the gas line pressure.
● Battery voltage verification: use the volt-meter to test the battery voltage, if the
voltage is 12.6 V or higher, the battery has enough power; If the voltage is below
12.6V, the battery will not turn the starter. Recharge or replace battery.
● Cylinder and plug wire check: Refer to the following photo, the plug gap between
the conductor and plug body should be 3-5mm.
Generator hunting elimination:
After starting the generator, if there is an irregular vibration or the engine seems to
speed up and slow down, the generator may be experiencing “hunting”. This is a
common occurrence until the engine adapts to the incoming fuel mixture. “Hunting” can
cause the electrical frequency to fluctuate >2Hz. In most cases the engine will adjust
itself after a couple of minutes. Except for sensitive, high precision electrical equipment,
“hunting” will not interfere with the electrical output of the generator and its’ output. In
the event high precision electrical equipment is being used, while the generator is
“hunting”, the high precision electrical equipment should be immediately disconnected or
turned off until the generator stops “hunting”.
44
USER MANUAL FOR BEEM OUTDOORS, LLC. 20KW
SILENT STANDBY GENERATOR SET
1.) General solutions for “hunting”:
● Check the fuel gas pressure, adjust as needed.
● Check for incoming fuel line kinks or blockage, correct as needed.
● Check to see of the speed sensor is lose, tighten as needed.
● Check the electrical speed regulator normal or not
2.) Measurements checking solutions for “hunting”:
● Close the incoming valve, attach a pressure meter to the inlet line,open the fuel
gas line and verify the incoming pressure is correct..
● Visually inspect fuel gas valves for damage, blockages, of debris.
● Open the fuel switch; listen to the valve to make sure solenoid valve.
● While engine is turned off, turn the speed sensor by hand to see if lose or tight.
● Check the electrical speed regulator for 12v DC power in/out.
3.) Final solution for “hunting”::
If the “hunting” problem is not corrected by solutions is #1 and # 2 above, replace
the electrical speed controller or actuator.
Trouble shooting no electrical power output
After starting the generator, electrical power output is not being produced, follow the
following steps to check and correct the problem:
1.) General solutions:
● Check the battery voltage (Voltage>12V).
● Check the voltage regular input and output cable for proper connections.
● Connect the voltage regular and the battery. Check to see if they show the same
input voltage.
● With the generator running and operating normally, the carbon brush should
produce approximately 70V of voltage.
2.) Measurements solutions
● Use a 20V multi-meter to measure the battery voltage, and the input side of the
voltage regular, and carbon brushes.
● Use a 200V multi-meter to measure the voltage at he carbon brushes.
.
3. Final solutions:
● When the correct voltage is correct on the input side but not on the output side,
there may be three (3) possible types of protection modes causing the problem (input
protection, sample losing protection, secondary winding protection). First, cut the
positive incoming power. After waiting 90 seconds, connect the incoming electrical
power again. Under normal weather and operating conditions waiting time should be
the 90 seconds. If there are abnormally cold or hot weather conditions or unusual
operating conditions, the wait time may be up to one (1) hour.

Voltage regular wiring:
Wiring: white wire and green wire (not distinguished between positive and negative
poles)
Secondary winding: Blue wire (not distinguished between the positive and negative
poles)
Input: Blue and white wire, green wire (blue and white wire, connect with the positive
pole, green wire connect with the negative polse)
Output: Red wire, black wire (connect with the carbon brushes, not distinguish
positive and negative poles)
When connecting to the generator stator input side, improper wiring connection can cause
the electrical components to burn out or cause damage to the generator.

Chapter 7: Engine Storage
Ⅰ. Prolonged engine storage
1. Remove dirt from the engine
2. Drain all engine coolant
3. Check all electrical cables are clean and in good condition
4. Remove all of the spark plugs from the engine block, add approximately 30g of
engine oil into each spark plug opening, turn the crankshaft about 20 revolutions, and
then place the spark plugs into each location on the engine block.
5. Use water proof petroleum jelly, heat to 100-200 degrees Fahrenheit and wipe on
the surface of all electrical contacts where they contact metal.
6. Add lubricating oil to each lubrication point.
7. Loosen the water pump belt.
8. Check the tightness of all the nuts and screws, tighten as needed.
9. Turn off the gas inlet valve, and depress the emergency stop button. Seal the
rubber line openings with rubber sealant to keep clean.
10. Remove the battery cable lines from the battery and remove the battery. Store
the battery in a dark and dry location. Every three months, recharge the battery
11. Cover with a protective material (such as canvas. water proof cloth, or oil paper).
12. Store in clean room not exposed to the sun with the best air temperature being
between 40 degrees and 95 degrees Fahrenheit with a relative humidity between
40-70%.
.
Ⅱ. Starting engine after prolonged storage period
1. Reverse the above steps starting with step number 12 and ending with step
number 1.
13. Start engine and check if running normally.
