INTRODUCTION
Cutler Hammer’s Westinghouse brand of Automatic Trans-
fer Switch Single Board Controller is a microcontroller
based transfer switch logic control package. The hard-
ware and software of the controller contains the intelligence
/ supervisory circuits which constantly monitor the condi-
tion of the power sources. It provides the intelligence nec-
essary for the operation of the transfer switch. The single
board controller may be used as a replacement for the
solid state logic control panel in the existing older version
of the Robonic Transfer Switches.
SPECIFICATION
The ATS controller has an operating temperature range of
-20 deg. C to +75 deg. C.
The controller circuit board is protected by an insulating
conformal coating.
The specification under normal operating condition 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.
Dial settings for Delay Time are +/-5% of indication.
