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 (Source I, Source II). 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. Key Controller features include AC voltage & frequency signal acquisition, control signal input/output, user interface (LCD display, LED indicator lights and keys), and RS485 communication (supporting MODBUS protocol). The Controller appearance, functions and features, technical parameters, accessory configurations, and size of the Controller will be described in this chapter. Also available is the optional C2000 Intelligent Controller with Energy Storage (hereinafter referred to as Controller with Energy Storage, or Accessory 1H). This design is based on the Standard C2000 Controller but includes capacitors in order to store enough energy to move the transfer switch to center-off when BOTH Source I and Source II fail at the same time.

Please note, the Transfer Switch that is used with the Standard C2000 and the C2000 with Energy Storage are different due to connector board differences. So, one cannot interchange these controllers on the same transfer switch.
1.3 Functions and Features Detecting and displaying the voltages, frequencies and three-phase imbalance of two AC input sources, alarming and displaying when failures occur as overvoltage, under-voltage, over frequency and under frequency, etc. Multiple operating modes: Automatic (Source I Priority, No Source Priority), Remote Control, and Manual. Center-off position delay and Center-off position protection. Center-off position delay: When the transfer switch transfers the load from one source to another source, the transfer switch should stay in center-off position for a period of time. This time can be settable by user depending on the load characteristics. The default setting is 0 seconds, in order to consume the load inertia and protect the load from getting damaged by the inrush current when the load transfers from one source to another source. Center-off position protection: When there are abnormalities with both Source I and Source II, the transfer switch will transfer the load to the center-off position to protect the load from getting damaged. Built in abnormal transfer diagnosis capabilities in order to protect the transfer switch. Utilizes high frequency switch power in order to have a wide input voltage range, suitable for terrible power. Capable of operating with DC 24V. Many settable options, including over/under voltage, over/under frequency for both sources, and switching time delays. User DI / DO Ports for external monitor and control. RS485 with MODBUS communications protocol. Up to 100 event log recording capability. Log is saved in the event of a power loss. The optional Controller with Energy Storage (Accessory 1H) has the added feature to switch the transfer switch to center-off position during Source I and Source II failure at the same time. This optional feature can work in Source I Priority and No Source Priority operating modes. And this feature is available only after the controller has been powered by AC input for 10 minutes.

1.4 Controller with Energy Storage (Optional Accessory, 1H) ASCO Series 230 C2000 Controller with Energy Storage has the following control principle:
Normally, the controller is powered by Source I, Line A and Line C (Line A and Neutral, when the source is single phase and neutral) or Source II, Line A and Line C. Once one of the sources has complete phase loss and the other source has either Phase A and / or Phase C loss, the controller loses power and the ATS will NOT be able to transfer because the motor has no power.
To avoid potential damage to the generator and / or the load side, it is recommended to purchase the Controller with Energy Storage (Accessory 1H). With this optional feature, when Source I and Source II experience power failure, the Controller with Energy Storage is able to power the controller and the motor so that the transfer switch can complete one-last transfer to center-off. When power is restored, the switch will return to normal operation and re-energize the capacitors for the next potential complete (Source I and Source II) power loss.
