ATS controller Y:YCM-controller. Installation type: integrated type; YCM-controller Electric capabilities and functions of YCM series controller: 1Voltage detection of main and backup power supply(under-voltage 60%-85% is available over-voltage of 120%) 2Free interchange among the three modes(self-transfer self-recovery; self-transfer non self-recovery; electric grid-generator) 3Fire fighting alarming linkage shift to 0 (insulated contact input) 4Automatic/manual operation options 5Issue generator starting signals under electric grid-generator mode 6Can set switch on and switch off delay period individually(freely adjustable range 0.5-30) Introduction of YCM series controller functions - Self-transfer and self-recovery(R) The acquiescent initialization tense is main power supply, when main power supply goes wrong, the switch will automatically shift to 0 after delay period, and then it will switch to backup power supply after closing and past the delay period. The switch will switch to main power supply while it recovers normal. -Self-transfer and non self-recovery(s) The controller will detect and shift between the normal and backup mode of two-way power supply and the acquiescent initialization tense is main power supply. When voltage of power supply appears abnormal (any path power supply appears over-voltage, lack phase) the switch will automatically shift to 0 position after switching on delay time and transfer to backup power supply after switching off delay time, but once main power supply recovers the switch will not automatically recover, only backup power supply goes wrong will it switch to main power supply again. -Electric grid-generator (F) The controller will detect the main power supply, for the main power supply will not start generating electricity under normal voltage if backup power supply is being used as a generator. This system will automatically assign a generator control interface to issue a generating signal (as a set of N.C. contacts) when the electric grid and voltage appears abnormal. After the generator starts as usual, the switch will automatically transfer to the backup power supply after the delay intervals. And while the electric grid voltage recovers normal the intelligent system will automatically disconnect from backup power supply after the delay intervals and switch to main power supply then stop generating.
