YCM-Ⅰcontroller
Electric Capabilities and Functions of YCM series Controller in YEQ2Y Automatic Transfer Switch:
1. Voltage detection of main and backup power supply(under-voltage 60%-85% is available over-voltage of 120%)
2. Free interchange among the three modes(self-transfer self-recovery; self-transfer non self-recovery; electric grid-generator)
3. Fire fighting alarming linkage shift to 0 (insulated contact input)
4. Automatic/manual operation options
5. Issue generator starting signals under electric grid-generator mode
6. Can set switch on and switch off delay period individually(freely adjustable range 0.5-30)
Functions of YCM series Controller Used in YEQ2Y Automatic Transfer Switches
(1) 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.
(2) 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.
(3) 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.
Structure and Characteristics of YEQ2 Automatic Transfer Switch
YEQ2 series of Digital Dual Power Automatic Transfer Switch consists of two 3-electrode or 4-electrode molded case circuit-breaker and some other accessories (assistance, alarming contacts) such as mechanical interlocking setup and controllers and so on. This series automatic transfer switch is divided into two types: integrated and split. Controller and implementary device of integrated type are installed on the same base integrated types while for the split type, the controller is set on the cabinet panel and the implementary device seated on the base is installed in the cabinet by the users. There should be a 2-meter long cable connecting the controller and the implementary device.
Characteristics of YEQ2 Automatic Transfer Switch:
-The reliable mechanical interlocking device and electrical interlocking protection between two breakers can thoroughly prevent two breakers closing at the same time
-Intelligent controller applies single chip as controlling core and have functions such as compact hardware, powerful functions, easy-expanding capabilities and high reliabilities
-Have several functions such as short circuit, over-voltage protection, under-voltage, lack phase, automatic transfer and intelligent alarming abilities etc
- Automatic transfer parameters can be set freely outside
-Intelligent protection abilities of generators
-This automatic transfer switch is equipped with fire control circuits, once the fire control center issued a control signal into intelligent controller the two breakers will close respectively
-Generator can start signal-issuing abilities and when main power supply goes wrong, ATS controller will issue starting signals and activate the generator automatically
