Chapter 1 Overview Chapter 1 Overview ASCO Series 230 C2000 Intelligent Controller (hereinafter referred to as Controller) is used to control the Series 230 transfer switch. The Controller is designed to control two sources. When either source has over voltage, low voltage, failure, or abnormal frequency, the Controller will instruct the transfer switch to transfer to a better source or transfer to the center-off position in order to protect the load.
