The Y-701/Y-702 series is an advanced dual power system controller with excellent compatibility for our full range of products. The series integrates microprocessor measurement unit and programmable output unit, in which Y-702 is equipped with communication unit to further expand the functional boundary.

For display, Y-701 uses traditional display, Y-702 is upgraded to LED display to meet the diverse needs of different users for display interface.

This series of controllers have a very practical adjustable switching delay function, and have a variety of adjustable working modes, which can be flexibly adapted to various complex power consumption scenarios. It is worth mentioning that the series is equipped with intelligent power module, greatly reducing the risk of human operation, for the stable operation of the system to build a strong security line.

The microprocessor-based Y-701/Y-702 series controllers have extremely high circuit sensitivity and can accurately capture subtle changes in the circuit such as over-voltage, under-voltage, and phase loss, and quickly output passive switch vector signal to ensure the efficient and stable operation of the dual power supply system, and provide a solid guarantee for the reliable power supply of all kinds of electrical equipment.

1.Attention:controller is equipped with the cable while out of factory,cable should

be right connected refer to the mark A/B/C/N.

2.FU1/FU2 normal power and standby power insurance tube,the value will

change depends on ATS model.

while equipped with GA type ATS:FU1/FU2=2A

while equipped with C , N , S type ATS,FU1/FU2=10A

while equipped with N , Q type ATS,FU1/FU2=16A

□ M3,M4:standby power passive closing auxiliary output, outputting time depends on ATS Model; about 3 seconds within magnet exciting coil, Electric type ATS can be more than10 seconds.

□ L2:standby power active closing feedback input, only limited to phase A/B/C

□ A2:standby power phase A output, feedback to the closing standby power.

□ A2,B2,C2,N2:standby power three-phase&four-wire input

□ T1,T2:All off signal output, can be active or passive depends on ATS model, when equipped with PC class three sections ATS, it is 220AC active output, and it is passive when equipped with seclusion type ATS.

□ F2,F1,F:in Y-701 controller,F1 and F are starting generator signal output; in Y-702 controller, F1 and F are programmable output.

□ A1,B1,C1,N1:normal power three-phase&four-wire input

□ A1:A phase normal output, feedback to closing normal power.

□ L1:normal power active closing feedback input, only limited to phase A/B/C.

□ M1,M2:normal power passive closing auxiliary output, outputting time refers to M3&M4.
