ATyS g are 3 or 4 pole automatic transfer switches, with positive break indication. They incorporate all the functions offered by the ATyS r, as well as functions intended for mains/mains and mains/genset applications.
In automatic mode they enable the monitoring of, and the on-load changeover between, two power supply sources, in accordance with the parameters configured via two potentiometers and four DIP switches. Remote monitoring of the ATyS g is possible with the optional RS485 communication module.
They are intended for use in low voltage power supply systems where a brief interruption of the load supply is acceptable during transfer.
ATyS g switches offer significant time saving during commissioning (process takes 2 to 3 minutes). Owing to the design that allows commissioning through just four potentiometers and four DIP switches, a screwdriver is all that is required to configure the parameters.
For added simplicity, they also offer an autoconfiguration function which enables automatic adjustment of the rated voltage and frequency.
Specifically designed for mains/mains and mains/genset applications
The ATyS g’s integrated controller has been designed to provide specific functions for these applications (genset startup, on-load or off-load tests...) together with the monitoring of the voltage and frequency of both sources for three-phase and single-phase networks.
The generator supply must be connected to switch II, located at the rear.
Optional RS845 communication module
An optional RS485 communication module (p/n 4825 0092) can be fitted to the top of the AtyS g controller.
It allows remote monitoring of available power sources and their parameters, timers, as well as carrying out generator tests. Communication speed is up to 38400 bauds.
