Supplier Description & Specifications:

ATyS g M automatic changeover switches

The ATyS g M switch monitors the supply from both mains and from generator. On mains failure, the switch provides an output to start generator and once the generator voltage reaches the correct level, switches over to the generator supply until mains is restored, causing the switch to change back to the mains supply and stop the generator.

Potentiometers for:

• Nominal voltage configuration
• Voltage and frequency threshold configuration
• Operating cycle configuration

DIP- switches for:

• 50 or 60Hz, single or 3-phase
• Delay in O position during I-O transfer cycles

LED indication of:

• Supply source availability, automatic mode, fault

External command inputs:

• Manual change of supply from emergency to main source
• Remote test on-load (or priority change)
• 1NO output relay for generator start/stop command
