ATS UNIT USE AND SAFETY PRECAUTIONS

WORK AREA

Do not use the product near flammable gases, liquids or dust. Keep the work area clean and well lit to avoid injuries. Keep unauthorized persons, children and animals away from the running product.

ELECTRICAL SAFETY

The product is energized. Observe safety precautions to avoid electric shock. Avoid operating the product in high-humidity environments. Do not allow moisture to enter the product, as this increases the risk of electric shock. Avoid direct contact with grounded surfaces (pipes, radiators, etc.).

Be careful when working with the power cord. Replace it immediately in case of damage, as damaged power cord increases the risk of electric shock. All product connections must be carried out by a certified electrician in accordance with all electrical codes and regulations. Do not operate the product with your feet in the water, on wet or damp soil. Do not touch live parts of the product. Keep all electrical equipment dry and clean. Replace damaged or worn wiring. Worn, damaged, or rusted terminals must be replaced as well.

PERSONAL SAFETY

Do not operate the product when you are tired or under the influence of potent drugs, alcohol or medication. During operation, inattention can cause serious injury. Make sure there are no foreign objects on the product when it is turned on. Do not overload the product; use it for its intended purpose only.

PLEASE NOTE! The total power of power consumers connected to the ATS system must not exceed the maximum permissible power for this ATS unit model.

OPERATING THE ATS UNIT

ATS UNIT FUNCTION

The ATS unit automatically starts the generator and switches over power consumers to it when the main power supply is deenergized.

PLEASE NOTE! Use the control cable to connect the ATS unit to the power generator; the generator must have a special connector for connecting the ATS.

OPERATING PROCEDURE

ATS CONNECTOR AND ITS CONNECTION

Number	Connection function
1	DC12V positive
2	Flameout signal line
3	DC12V negative
4	Start-up relay
5	Automatic damper control line
6	Oil valve control line
7	Positive terminal of DC12V output
8	Negative terminal of DC12V output

Connect the ATS unit as shown in Figs. 2-5.

AUTOMATIC MODE

Turn the start key on the generator control panel to “ON” (for gasoline generators). Set the ATS unit main switch to “ON”. The “AUTO” LED light indicates that the ATS system is in automatic mode.

When the main power supply is disconnected, the ATS system automatically starts the generator in 2 seconds. After 5 seconds following the generator startup, the system will switch over power consumers to the backup power source (generator).

In case of unsuccessful startup, the ATS system attempts to start the generator three times with an interval of 6 seconds between the attempts. If all three attempts are unsuccessful, the ATS unit will stop trying to start the engine and signal an error.

GENERATOR STOP IN THE AUTOMATIC MODE
If the generator was started in automatic mode, to stop it, turn the switch to the «off» position and shut down the generator using the multi-function switch on the generator. Or press the emergency stop button.

TEST MODE
If it is necessary to start the generator without connecting it to the electrical network, turn the main switch of the ATS unit to the «OFF» position.

BATTERY
The ATS unit battery is charged automatically. The maximum charging current is 2A.

ATTENTION – DANGER! It is forbidden to use the generator using LPG as fuel in the mode of automatic start of ATS unit! It is dangerous to leave the connected LPG cylinder open in the standby mode, a gas leak can occur, which can lead to an explosion!

CONNECTION OF THE GENERATOR AND ATS TO THE BUILDING POWER SUPPLY NETWORK

The wiring diagrams have been developed in accordance with the guidelines for planning, installation and operation of emergency power systems developed by European power grid operators.
We recommend using three wiring options.
The generator must be connected via a 32A 230V CEE socket.

The generator must be grounded using either the screw connection or the PE pin in the generator CEE socket.

The PE pin (earth) in the generator sockets is connected to the generator housing. The N pin (neutral) in the generator sockets is NOT connected to the generator housing and must be connected to the main earthing busbar as a separate cable at the point of connection of the neutral from the generator on the AVR for the TN power supply system. When switching power supply to the generator side as instructed, the ATS disconnects not only the phase conductors, but also the neutral conductor of the external power grid.

DISCLAIMER:
This material is for informational purposes only and does not constitute a manual for installing the equipment or connecting it to the mains, but we strongly recommend that you read the instructions below. Equipment connection must always be carried out by a certified electrician responsible for the installation and electrical connection of the equipment according to local laws and regulations. The manufacturer assumes no liability for improper connection of the equipment or for any material or physical damage that may result from improper installation, connection or operation of the equipment.

OPTION A FOR SINGLE-PHASE EXTERNAL POWER SUPPLY AND 230 V EMERGENCY ELECTRICITY CONSUMERS.
This option assumes that generator supported electricity consumers may be supplied from an external power grid up to 50 A or from a KS 8100iE ATSR generator up to 32 A (Fig.1 in the Annex).

OPTION B FOR THREE-PHASE EXTERNAL POWER SUPPLY AND 230 V EMERGENCY ELECTRICITY CONSUMERS
This option assumes that generator supported electricity consumers may be supplied from an external power grid up to 50 A or from a KS 8100iE ATSR generator up to 32 A (Fig.2 in the Annex).

OPTION C FOR THREE-PHASE EXTERNAL POWER SUPPLY AND 230 V EMERGENCY ELECTRICITY CONSUMERS
This option assumes that generator supported electricity consumers may be supplied from an external power grid up to 25 A per phase or from a generator up to 25 A in total (Fig. 3 in the Annex).

ATTENTION Emergency power supply from the KS 8100iE ATSR generator is possible only for single-phase consumers.
