Series 230 Automatic Transfer Switch C1000 Intelligent Controller User Manual
Chapter 1 verview
Series 230 C1000 Intelligent Controller (hereinafter referre to as Controller) is use to control the Series 230 transfer
switch. The Controller is esigne 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 or er to protect the loa .
Key Controller features inclu e AC voltage & frequency signal acquisition, control signal input/output, user interface
(LED in icator lights, DIP switch an push button). The Controller appearance, functions an features, technical
parameters, accessory configurations, an size of the Controller will be escribe in this chapter.
1.1 Appearance
Please refer to Fig 1-1 for the appearance of the Controller.
Figure 1-1 Controller Appearance
1.2 Functions an Features
 Detecting the voltages, frequencies of two AC input sources, alarming when failures occur as overvoltage,
un er-voltage, over frequency an un er frequency, etc.
 Multiple operating mo es: Automatic (Source I Priority, No Source Priority), Remote Control, an Manual.
 Center-off position elay an Center-off position protection mo es.
 Center-off position elay mo e
 When the transfer switch transfers the loa from one source to another source, the transfer switch shoul stay in
center-off position for a perio of time.
 This center-off position elay time can be settable by user epen ing on the loa characteristics. The efault
setting is 0 secon s, can be set to 5 secon s, in or er to consume the loa inertia an protect the loa from
getting amage by the inrush current when the loa transfers from one source to another source.)

This light in icates the operating status of the Controller. When it is on or flashing, it in icates
normal operation; an when it is off, it in icates over voltage setting operation or abnormal
operation.
When it blinks rapi ly it in icates that the Controller is running in manual mo e. When it
blinks slowly it in icates that the Controller is running in remote mo e.
Alarm In icator
(re )
When in Source I Priority Mo e, the alarm in icator will be on when the Controller etects
such abnormalities as un er-
voltage, overvoltage, phase loss an power failure on Source I.
It ignores the status of Source II.
When in the No-Source Priority Mo e or the Remote Mo e, the alarm will be on when the
Controller etects such abnormalities as un er-voltage, overvoltage, phase loss an power
failure on Source I an Source II.
Otherwise, the alarm will flash uring any critical failure, such as switch operation failure or
fire alarm.

The push button is on the right si e of the Controller panel, which can be easily manipulate .
Press it for 3 secon s to clear alarm. When the alarm in icator is on or flashing, press this button for 3 secon s to
clear the alarm in ication.
Manual Operation:
Step 1: Set the DIP Switch bit 7-8 to ON, ON. The RUN in icator starts flashing rapi ly. One of three position in icators
on the bottom left of the panel starts flashing, as shown in Figure 5.
Step 2: The flashing in icator in icates the target position that ATS woul transfer to, press the button quickly (less
than 3 secon s) to switch the target, an then three in icators woul flash an rotate one at a time.
Step 3: After selecting the target that woul be switche to, press the button for 3 secon s, an then ATS woul
transfer to the target position.
Step 4: Set the DIP Switch bit 7-8 to auto or remote mo e to exit from the manual operation mo e.
3.3 Time Delay Setting
The two knobs are for setting the ATS’s time elay. Position I transferring to position II or Position II transferring to
position I, as shown in Figure 3-2.

Please use a small flat-en s screw river for a justment.
Time Delay for transferring from Position I to Position II: min. 0 secon , max. 5 minutes.
Time Delay for transferring from Position II to Position I: min. 1 secon , max. 30 minutes. This Time elay is use to
wait for Source I power to recover to stable con itions.
3.4 DIP Switch
The DIP switch is on the upper-right corner of the Controller panel, with 8 bits in total. When the white sli er of each bit
is on the top, it means ON, an when it is at the bottom, it means OFF, as shown in Figure 3-3.

This chapter intro uces how to test the controller after installation, to make sure everything is working properly. This
chapter also inclu es maintenance an troubleshooting information.
4.1 Start Up / Function Test
Please refer to ASCO Series 230 Transfer Switch Manuals for start-up an functional testing proce ures.
4.2 Maintenance
To ensure consistent reliability of the transfer switch to make sure it is operating normally, regular maintenance testing
shoul be con ucte . It is recommen e to o so once every three months.
4.3 Common Troubleshooting
Before transfer switches any positions, please make sure that the interface wiring an controller setting are reliable
an correct. After that, Power on an observe the in icator status, an carry out the following trouble items, as
necessary.
