Figure 76: Example of an ATS control panel
Figure 76 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 75.
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.
