Fault Analyse and remove
It is no response after start the switch, and the electric operating mechanism not action after pressthe instruction button: Please check the fuse protector and the wiring connection.
The three phases powerand the neutral line must connected, the fixed screw must tighten on the cable head.
After making the power,although each phase voltage all in normal,but the panel display still in under voltage,please check the power if connection well,if have lost phase status.After making the power,controller have electric,but the motor operation mechanism no acition,please check the switch unit two piece fuse if due to motorized operation over current then fused,should replace new one to try.
Error Display code:
Display: “E--1” means main power side circuit breaker trip out.
Display: “E--2” means emergency power side circuit breaker trip out.
Display: “E--3” means motor or mechanism fault result change over no action or out time long.
Display: “E--4”means mechanism position detection error results faults
Other Notice
The switch unit should be periodic inspection and maintained as per the circuit breaker, electric operation mechanism’s requirements. The automatic controller is maintain-free under normal use.
If long time no use the product, please notice dampproof and dustproof, and please debug the switch as per the above description, when everything is normal then could operation.

Precautions
Setting the operating process
Parameter amend operating process
The way to enter into: Continue to click "Manual/Auto" button ten times enter into the manu of parameter amendment. The fourth code display flicker.Amend parameter: Click "Main" button turn page down or "Emergency" button page turn up. Click "OFF" button confirm enter into to amend parameter, the last threepositions flicker, then click "Mainl" or "Emergency" to increase or decrease the number, click the "OFF" save the parameter and into the next options. Exit: 10s no click action will automatic exit or click ”OFF”ten times.If you no click the save button it will not save the amended parameter and exit directly.
Voltage calibration operating process
Enter into: In automatic mode, click "Emergency" ten times enter into, the fourth position show "Three" and flicker.
Calibration voltage: Must debug all the main power and emergency power voltage to AC220V, then click "OFF" save the calibrate data at present.
Exit: In 10s no click action will automatic exit or click "Emergency" ten times to exit.
Change record query
Enter into: In automatic mode, meanwhile click the "Main" and "Emergency" to enter into the recently change record.
E-01: The newest change record recently.
