PRODUCT DESCRIPTION 3
The ATS unit (Automatic Transfer Switch) is designed to automatically control the generator set and switch
the power supply from the mains to the backup generator and vice versa in automatic or manual mode. The
ATS unit controls the generator set using 8-core wires. The user can start/stop the generator automatically/
manually, eectively monitor the output voltage of the generator, mains and load.

The ATS unit consists of a housing that can be mounted on a wall. The ATS unit is connected to the
generator set via a special control cable (included) and a power cable. The integrated clamping terminals
are used to connect the generator output, redundant electrical devices and AC mains.

OPERATING THE ATS UNIT 6
MANUAL MODE 6.1
The ATS unit automatically starts the generator and transfers load to it when the main power supply is
disconnected.
ATS unit has two modes:
- Manual mode
- Automatic mode
If the ATS unit operates in manual mode, no mains voltage control is provided; the generator can only be
controlled in manual mode.
After connecting to the ATS unit, the generator can be controlled using buttons 4 and 5 on the control panel.
The time required to warm up the engine before connecting the load is adjusted by the operator. The load
should be connected during stable operation of the generator set.
AUTOMATIC MODE 6.2
In automatic mode, the ATS unit continuously monitors the presence of the mains voltage. The mains
indicator (7) is on when the mains voltage is present.
When the mains supply is absent for 5 seconds, the ATS unit gives a signal to start the generator engine.
While the engine receives a start signal, the air choke switches to mid-position and the time of the electric
starter relay is 4 seconds.
After the generator receives the voltage output signal, the ATS unit switches the air choke to the open
position (within 5 seconds in summer mode and within 15 seconds in winter mode after the engine starts).
In the absence of the voltage output signal after disconnecting the electric starter relay, the system will make
another 5 attempts to start the engine.
If after the 5th attempt the engine does not start, the system will display an error message and the engine
operating indicator (10) will ash.
TO OPERATE THE ATS UNIT IN MANUAL MODE, PROCEED AS FOLLOWS:
1. Connect the ATS unit to the generator set and mains (see Diagram 1).
2. Turn on the power using the power switch (1).
3. Set the ATS mode switch (3) to manual mode.
4. Turn the ignition key on the generator panel to “ON”.
5. Press the button (5) on the ATS unit to start the generator set. During stable operation of the generator,
press the button (4) to connect the load.

TO OPERATE THE ATS UNIT IN AUTOMATIC MODE, PROCEED AS FOLLOWS:
1. Connect the ATS unit to the generator set and mains.
2. Connect the line of primary power consumers “Load”.
3. Turn on the ATS power using the power switch (1).
4. Select summer or winter mode with the switch (6).
5. Set the ATS unit to “AUTO” with the mode switch (3).
6. Turn the ignition key on the generator panel to “ON”.
If the ATS unit detects the mains voltage, it will automatically switch to “standby” mode and power
consumers will be supplied from the mains.
In the event of power outage, the ATS unit automatically starts the generator set according to the operation
principle of the ATS unit and switches the power supply to the backup generator. The generator battery is
also charged from the mains in automatic mode.
When the mains supply is disabled, the system starts the generator engine in the manner described above
and switches the power supply of the redundant devices to the generator.
If the engine starts successfully, the engine operating indicator (10) and the generator power indicator (9)
will glow steadily. After the engine starts successfully, the system will pause to warm up the engine before
connecting the load.
In summer mode the delay will be 10 seconds, in winter mode the delay will be 25 seconds. After this
time, power switches will turn on and power consumers will be supplied by the generator. The output load
indicator (8) will further glow steadily.
When the mains supply is restored, the system switches the load to the mains supply within 3 seconds. If
the mains voltage remains stable for 10 seconds, the ATS unit gives a signal to stop the generator.
In the “Auto” mode, the battery is automatically
charged.
PLEASE NOTE!
When the ATS unit is in automatic mode, the generator can be controlled in automatic mode. When
power consumers are supplied from the mains, the generator is disabled
After the mains voltage is disabled, the ATS unit will start the backup generator within 4±2 seconds, which
will turn on in 4 seconds. After the generator starts, there is a delay for air choke adjustment (5±1 seconds
in the warm season and 15±1 seconds in the cold season).
The time interval between the generator start and the connection of the load is 10±1 seconds in the
warm season and 25±1 seconds in the cold season. When the mains supply is restored, the generator
stops after 15±2 seconds. When power consumers are supplied from the mains, the generator battery is
simultaneously charged by the ATS unit with a voltage of 13.2 V.
If ATS unit fails to start the generator set in automatic mode on the rst try, it will restart. After three failed
attempts, an alarm is triggered.
After resetting the ATS unit and turning on the power, the ATS unit will automatically restart the generator.
