Hi Suksan
Again, the troubleshooting would be many steps.
Please find a way to let me contact the onsite engineer directly.
If you change the value in 31.06, still shows APR, please check the encoder cable or replace the encoder to try.
Also, when the encoder is on the right. The upper position value should be smaller than the lower position value.
For adjusting the value, please see below steps.
1) Shorted the G and X4, entering the test mode.
2)Adjusting the value of the encoder(Pressing the triangle on the right four times to check the value)
Know-how:The transducer read the value with the communication cable.
The value decrease when the door open and increase when the door close.
So as to say that if the value is too large, you can use the following way to correct the value.
3) Disconnect the cable then close the door, after that, reconnect the cable and open the door.
The value can be corrected after repeating two or three times.
(The transducer cannot read the value when the cable is disconnected.
Reconnect the cable, the value can be read, and door opening decrease the value as told before.)
I will check my email twice at 09:00 and 14:00. If you have anything in emergency, please call me on +86 13760882606.
