4. ATS operation principle

Startmaster BS 500 can be operated in two modes:

1 Manual mode

2 Automatic mode

When the ATS is operated in manual mode, mains voltage is not monitored. Generator start and

load connection is provided by pressing buttons (4) and (5) on the front panel of the ATS. The time

needed to warm up the engine before connecting the load is controlled by the operator.

In the automatic mode, the ATS is continuously monitoring the availability of mains voltage. Mains

voltage control indicator (7) is on when the mains voltage is available.

In case of mains voltage absence during 5 seconds, the ATS gives the signal to start the power

station engine.

While receiving the engine start signal, the choke is transferred to the middle position, and the

electric starter relay is connected for 4 sec.

Upon receiving the signal of generator output voltage availability, the ATS transfers the choke to the

open position (in summer mode – i , in winter mode – in seconds after successful

start).

If there is no output voltage after electric starter relay shuts off, the system will attempt to start the

engine up to 5 times more. If after the 5th attempt the engine does not start, the system will report the

error and the engine indicator (10) will be flashing.

If the engine starts successfully, the engine indicator (10) will be glowing continuously.

n 5 seconds 15

After successful engine start, the system will make a delay before load connection, necessary to

warm up the engine. In the summer mode the delay will be 10 sec., in the winter mode – 25 sec.After

this time the power contactors will be switched and the power supply of the load will be provided by

the generator. Two indicators (8) and (9) will be glowing continuously.

After mains supply is restored and is stable for 10 seconds, the system transfers the load to the

mains and gives the signal to stop the generator engine.

1 Connect the automatic transfer switch to the power station and to the mains.

2 Connect the line of the reserved devices.
