Analysis and solution
1
The mode indicator light does not respond
or the indication is incorrect.
Check that the control panel mode indicator
wiring is correct or that the contact is poor.
2
After swiping the card, there is only a speed
gate unlocked.
Check the mode setting of the master and
slave devices and the 8-core, 2-core
connection lines. See the wiring diagram for
the specific connection circuit.
3
The barrier doesn’t close when the opening
delay time is ended.
Check to see if the opening delay time is too
long or whether the IR sensor is covered.
4
When the gate is self-tested, the swing arm
is not in the normal closing position!
In the process of self-test, there are obstacles,
please remove the obstacles, restart the self-
test after power-on!
