3.3 MICROPROCESSOR BASED LOGIC PANEL
The AGswitch is a microprocessor-based transfer switch
logic control package. The hardware and software of
the controller contain the intelligence/supervisory cir-
cuits that constantly monitor the condition of the power
sources. It provides the intelligence necessary for the
operation of the transfer switch (Figure 3-4).
The ATS controller has an operating temperature of -20
to 75° C.
The Controller circuit board is protected by an insulating
conformal coating.
The specifications under normal operating conditions
are as follows:
• Tolerance for voltage sensing function:
±2% of setting
• Tolerance for frequency sensing function:
±0.2 Hz of setting
• Accuracy of time delay range:
±2% of setting
3.4 OPTIONS
A variety of switch options are available to meet a wide
variety of application requirements. Individual options or
option combinations permit a switch to be tailored to
individual needs. Options are numbered with an associ-
ated description. More detailed selections that must be
made within a specific option are lettered.
