Figure 78 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
77.
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.
