Frequently Asked Questions
Q
How does an ATS function?
A
An ATS functions as a double-throw switch that connects one of two sources of power to a common load. It has interlocks which provide source to source isolation. The ATS is made up of two core components, a controller and a switching mechanism. The controller monitors both sources of power; if a loss is detected will start a generator and initiate a transfer sequence. When signaled by the controller, the switch mechanism will energize a coil which will move the switch to the alternate source. Once the primary source returns the controller transfers the switch back and shuts down the generator.
Q
Is my generator compatible with an ASCO transfer switch, and where do I land my engine start connections?
A
ASCO 7000 SERIES transfer switches can accommodate any generator brand as long as it is has a 2 wire input engine start signal for automatic engine control. These input wires are connected to the engine start contacts of the transfer switch; which will turn the generator ON and OFF. The engine start contacts are also known as feature 7, which consists of a NC contact that de-energizes (closes) to send an engine start signal, and feature 8, which has of a NO contact that de-energizes (opens) to send an engine start signal. Refer to the switch wiring diagram for the terminal connections.
Q
How do I contact a service technician?
A
Contact a local ASCO Power Services representative by calling the toll free hotline (1-800-800-2726), then go to option 2 then 3 on the prompt or connect with any customer service representative. They will transfer you to a local service technician’s office in your area.
Q
How do I communicate with the ATS?
A
The Group 5 controller can communicate via ASCOBusII (ASCO use only) or MODBUS protocol. To communicate with the ATS, you need the optional communication module (Acc.72EE2). This module supports Ethernet and RS-485 connection; which the customer can use to access data for external systems. This module also provides SNMP, email, and webserver capabilities. It serves as a gateway to other devices that will communicate with Group 5.
Q
What is the Withstand and Closing Rating and which breakers are tested with an ASCO transfer switch?
A
Refer to Publication 1128 R20 for WCR and tested breakers for ASCO switches.
