Figure 65: Example of an ATS control
panel
Figure 65 is an example of the control panel of an
ATS.
The upper part of the control panel consists of a
mimic diagram showing the control flow.
“NS = 0” means the normal source is not available.
“NS = 1” means the normal source is available.
“R” is the reserve source.
The timing variables T1 through T5 are described in
Figure 64.
The knob at the bottom of the control panel controls
the actions of the ATS:
●
The ATS can be set to use the normal source.
●
The ATS can be set to use the reserve source.
●
The ATS can be set to automatic mode, which will
use the normal source and will automatically
switch to the reserve source in the event of a
failure of the normal source.
●
The “Stop” setting opens the ATS’s circuit
breakers.
