Performance and characteristics

Built-in sampling line is adopted for export products, so there is no need to add additional sampling line when customersuse them.

External safety seat for easy maintenance.

The intelligence type with full functions, the anti-interference ability strong cent shape and the economical reliable basic type are optional.

Full functions, with overvoltage, undervoltage and open phase switching function.

The intelligent controller adopts lC microcontroller as the control core, which has powerful function, easy expansion and strong anti-interference ability.

Double breakpoint horizontal pull mechanism is adopted in the mouth switch, which is safe and reliable in switching on and off.

The actuating load disconnecting switch is equipped with mechanical interlock device to ensure reliable operation of normal and standby power sources.

lt adopts the zero-position technology, which can be set to zero compulsivly in case of emergency(at the same time cut off the two standing power sources), and both meet the requirements of fire linkage.

lt has obvious on - off position indication, padlock and other functions, which can reliably realize the isolation of power supply and load.

Four operating functions: emergency manual operation, electric remote control operation, automatic control state emergency disconnect operation Automatic control operation.

Three stable working states (I-O-ll): common closing and standby opening; commonly opening, standby closing; common and standby power sources are both disconnected.

Normal working conditions

The operating environment temperature range is-25℃-+70℃, and the storage environment temperature range is -55℃-+85℃.

The elevation of the installation site shall not exceed 2000m.

The relative humidity of the air at the installation site should not exceed 50% when the ambient air temperature is +40℃. The relative humidity can be higher at a lower temperature. For example, when the average minimum temperature of the wettest month is +20℃, the average maximum relative humidity of that month can reach 90%. Appropriate measures should be taken to prevent condensation caused by temperature change.

Usage method

1. Use method of GN single phase sampling basic auxiliary terminal

The terminals of, 201, 206 shall be short-connected with wires for remote control (cabinet door control conversion), and the disconnection shall be automatic.

205 is the remote COM port.

When the closed signal is detected at port 202, 205, the "ll stand by power" is normal , and the product is converted to the "ll standby" position.

When the closed signal is detected at ports 205 and 204, the product will switch tothe "ll standby" position if the "ll standby power" is normal.

When the closed signal is detected at ports 205 and 203, the product will switch to the "O power off "position if one or two of the " l common power supply "or "ll backup power supply" are normal.

Port 101, 102 is the fire-fight power supply DC24V (9-36V,101 is negative, 102 ispositive, polarity should not be reversed) input, the product will perform the fire linkage function.

Port 103,104 is the feedback signal output after the product performs the fire linkage function, a group of passive signal dry contacts.

Port 105,106 is the generator start signal. Connect this port to the generator controller to realize the generator start and stop control.

The work zero line input of 3P: 301 is the common zero line, 306 is the standby zeroline.

302 is the COM terminal of position indicating signal.

Switch debugging description

1. The installation and debugging of the product shall be carried out by professionals and those who are familiar with the switch equipment operations.

2. The corresponding protection and preventive measures should be considered before debugging. The connection mode of the switch main loop must make the lead wire free from any pressure or strong action.

3. Before debugging, check whether the switch is not damaged or has any other harmful environmental impact, and check whether the wire head should be loose during transportation; Clean up dirt, especially on the surface of insulation.

4. When connecting the primary circuit, it should be noted that the phase sequence of the main and standby power must be consistent; when connecting the secondary control circuit, it should be operated strictly in accordance with the instructions; when the switch is installed, it must be well grounded.

5. After the product is installed, the power will be turned off. Take out the special operating handle supporting the product and turn it from the usual to the standby, and then from the standby to the three cycles in common use.

6. Check the wiring and secondary loop at a time, after confirmed, the products are in a common location, were used and the standby power supply, and then disconnect common power supply, the product after a delay the transformation to the standby power, restore common power supply, then after time delay shall be returned to the common power supply (except since couldn't from complex), three loop operation and each time interval of more than 20s.
