Solution
Check if AP is set to 00. If yes, change to correct application setting.
1) Check if IR1 is not connected, or wire is cut.
2) Check IR1 connection, change wires if needed.
3) Align IR transmitter and receiver to make sure both LED is on,
instead of blinking. Make sure there is nothing hanging on gate that
may cause IR blocking.
1) Check if IR2 is not connected, or wire is cut.
2) Check IR2 connection, change wires if needed.
3) Align IR transmitter and receiver to make sure both LED is on,
instead of blinking. Make sure there is nothing blocking the IR.
1) Check if IR3 is not connected, or wire is cut.
2) Check IR3 connection, change wires if needed.
3) Align IR transmitter and receiver to make sure both LED is on,
instead of blinking. Make sure there is nothing hanging on gate that
may cause IR blocking in short time.
1) Check if the 8.2 kOhm safety edge is properly connected or if the
8.2 kOhm resistor is installed.
2) Check safety edge wires and replace wire if needed.
3) Check if safety edge is pressed.
