10
Test Position ( Green )
Indicates that the ATS-380 controller is setting to
TEST function.
Normal Source Available ( Green )
Indicates that the normal source is available and the
voltage and frequency are within the programmed
parameters.
Normal Source Connected ( Green )
Indicates that the transfer switch is connected to the
normal source.
Standby Source Available ( Green )
Indicates that the standby source is available and
the voltage and frequency are within the
programmed parameters.
Standby Source Connected ( Green )
Indicates that the transfer switch is connected to the
standby source.
Load Connected ( Green )
Indicates that the load is connected to the normal or
standby source.
Normal Over Voltage ( Red )
Indicates that the normal source is unavailable and
the voltage is over the programmed parameters.
Normal Under Voltage ( Red )
Indicates that the normal source is unavailable and
the voltage is below the programmed parameters.
Normal Over Frequency ( Red )
Indicates that the normal source is unavailable and
the frequency is over the programmed parameters.
Normal Under Frequency ( Red )
Indicates that the normal source is unavailable and
the frequency is below the programmed parameters.
Standby Over Voltage ( Red )
Indicates that the standby source is unavailable and
the voltage is over the programmed parameters.
Standby Under Voltage ( Red )
Indicates that the standby source is unavailable and
the voltage is below the programmed parameters.
Standby Over Frequency ( Red )
Indicates that the standby source is unavailable and
the frequency is over the programmed parameters.
Standby Under Frequency ( Red )

SECTION 4 : OPERATION
4.1 General
This section specifically describes the operation and
functional use of the ATS-380 controller. It is divided
into four main categories:
●
Automatic mode
●
Engine test mode
●
Off mode
●
Programming mode
The practical use of and operation within each
category will be discussed. In this section it is
assumed that prior sections were reviewed and that
operator has a basic understanding of the hardware.
4.2 Automatic Mode
The automatic mode of the ATS-380 controller
provides for automatic transfer and retransfers from
source to source as dictated by the features
supplied and their programmed values.
The ATS-380 controller intelligence and supervisory
circuits which constantly monitor the condition of
both normal and standby power sources thus
providing the required intelligence for transfer
operations.
For example, automatically initiate an transfer of
power when power fails or voltage level drops below
a preset value. Exactly what the ATS-380 controller
will initiate in response to a given system condition
depends upon the combination of standard and
selected optional features.
