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 flash.
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.
