ASCO Series 2 0 Automatic Transfer Switch C2000 Intelligent Controller User Manual
Chapter 1 verview
ASCO Series 2 0 C2000 Intelligent Controller (hereinafter referred to as Controller) is used to control the Series 2 0
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.
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.

1.2 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 modes.
 Center-off position delay mode
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 mode:
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 (80Vac~480Vac).
 Capable of operating with DC 24V.
 Many settable options, including over/under voltage, over/under frequency for both sources, and switching time
delays.
 Configurable DI / DO Ports

WARNING
！
！！
！
Grounding is very important in order to protect the automatic transfer switch (switch and controller) from electrical disturbances,
lightning, electromagnetic disturbances, etc.
Locate the two connection cables 2 0S400SLW01-1 (Power Cable) and 2 0S400SLW01-2 (Signal Cable) found in the
transfer switch accessories. First connect the Power Cable to the X1 Power Connectors located on both the Controller
and the transfer switch. The Power Cable is labled to identify which end goes in which connector. Next, connect the
Signal Cable to the X2 Driver Connectors located on both the Controller and the transfer switch. The Signal Cable is
labled to identify which end goes in which connector.

This light indicate the operating status of the Controller. When it is on, it indicates normal
operation; and when it is off, it indicates abnormal operation.
Mode Indicator
(green)
When it is on, it indicates that the Controller is running in auto mode. When it blinks slowly it
indicates that the Controller is running in manual mode. When it blinks rapidly it indicates
that the Controller is running in remote mode.
Alarm Indicator
(red)
When in Source I Priority Mode, the alarm indicator will be on when the Controller detects
such abnormalities as under-voltage, overvoltage, phase loss and power failure on Source I.
It ignores the status of Source II.
When in the No-Source Priority Mode or the Remote Mode, the alarm will be on when the
Controller detects such abnormalities as under-voltage, overvoltage, phase loss and power
failure on Source I and Source II.
Otherwise, the alarm will flash during any critical failure, such as switch operation failure or
fire alarm.
Source I Available Indicator
(green)
When it is on, it indicates normal operation of Source I. When it is off, it indicates that Source I
is not connected or loss of power.
Source II Available Indicator
(green)
When it is on, it indicates normal operation of Source II. When it is off, it indicates that Source
II is not connected or loss of power.
Source I Accepted Indicator
(green)
When it is on, it indicates that Source I is connected. When it is off, it indicates that Source I
is in the process of switching off or not connected.
Source II Accepted Indicator
(green)
When it is on, it indicates that Source II is connected. When it is off, it indicates that Source
II is in the process of switching off or not connected.
Center-off Position Indicator
(yellow)
When it is on, it indicates that the load is in OFF status. When it is off, it indicates that the load
is not in OFF status and it is supplied by either Source I or Source II.
