1.3. 9 beautiful shape, small volume, light weight. The logic control board can control operation of the motor (inside the switch) using different logic to make sure the switch on it's position.


1.3 Features

ATSE  series as the main, dual power automatic transfer switch is mainly used in the first class load and second class load (which need back-up power) confirmed by the nati- onal regulations , suitable for highrise buildings, post and telecommunications, coal and shipping, industrial assembly line, health care, mditary facilities, etc. The main standby power can be grid, generator, battery, etc. The main standby power can be customized by users. Transfer time of the main switch body is not more than 1s. Users can make special delay when necessary. The main power takes priority over the main standby power when supply electricity together.

1, Electric lock: control the power of control circuit inside the switch. When the electric lock turned on, the switch can be remotely operated, otherwise the switch will be hand operation.

2, Operation handle: electric lock must be closed when using operation handle.

3, Mechanical padlock: Before you overhaul, you must turn off the electric lock, use the operating handle to force the switch to “0” position, pull the mechanical padlock and lock it.

4, Position indicator: indicate working status of the switch (I, 0, II).

5, The control voltage: AC220V.

6, The switch body: part in the front is line I, connect with the normal power. Part at the back is line II, connect with the standby power.

3.1 switch wiring instructions (see 2.2 switch structure)


3.1.1 switch from left to right, I copper busbar connect with A, B, C, N of Commonly used power (in the front) and II connect with standby power (at the back).

3.1.2 control power is taken from C of commonly used power and N of standby Power

3.1.3. control power AC220V of line I connect to terminal 102-103, control power AC220V of line II connect to terminal 104-105, 102 is fire wire for commonly used power and 104 is fire wire for standby power.

3.1.4 terminal 101, 106, just as a light control power, of which 106 is fire wire. Note that 101, 106 can not connected to any other lines.

3.1.5 When the top (bottom) of line I inset wire, A, B, C, N at the bottom (top) use conection of copper busbar to output it. And line II use wires.

 

4.1 Common problems and solutions

 

Problems

Reasons

Solutions

Power on, ATS does not work

1. Whether the button pressed on the automatic position

Choose the automatic position

2. Whether working power of the switch is connected

Access to the control power correctly

3. if connection mode of terminal 2 is correct

Access to signal control line correctly

4. The fuse is damaged

Replacing the fuse

Power on, circuit board burned

Check line 101-106 to make sure it is normal

Replace the circuit board
