Introduction
Y-701/Y-702 series Dual- Automatic Transfer Switch Controller is an ideal ATS controller which equipped with Microprocessor Measuring unit,Programmable Output unit,Communication unit(only 702),Indicator Display(701 NORMAL,702 LED) function,adjustable Conversion Delay function,adjustable working models and Intelligent Power Module to reduce the risk of man-made operation.
Due to the core is made up of microprocessor,Y-701/Y-702 series controller can detects any tiny changes(over-voltage,under-voltage and lacking phase) of the circuit and output the passive switch quantity signal.

Operational environment
□ The ambient temperature should be higher than -10℃ and lower than 60℃.
□ the ambient altitude should not be higher than 2000m.
□ the ambient electrical pollution class should not be higher than level 3.
□ the ambient relative air humidity should not be higher than 50%,40℃,the ambient temperature should not be higher than 25℃ while in the wettest month(The average maximum humidity of the month should be lower than 90%).
□ If the environment is not up to the standard,the demand-side should notice the supply-side in advance.

Product Features
Y-701 series Dual-Automatic Transfer Switch Controller -1
Note: only the solid squares have the function

function introduction
□Self-input and self-restore.when the normal power was broke down(lacking phase,over-voltage or under-voltage),The ATS will connect up to the standby power until the grid back to normal.
□ Self-input but no self-restore.not same to the 1,the switch will keep connecting up to the standby power until manual operation.
□ Power port share to each other. Followed 2,now the power grid is right,and the switch is connecting up to standby power,till the standby power break down,the switch will turn back to the power grid.
□ Error alarm.when the ordered instruction can't be execute in the prescribed time,the controller will stop executing(outputting),and the Y-701's indicator light will start system checking(at same time the Y-702's indicator light shows dual flicker).press the"Manual/Auto" button to stop the alarm.
 
Setting mode of Y-701 controller
