12. TROUBLESHOOTING GUIDE
1) The chain drops by a few centimetres at the end of the close cycle.
At the end of the fi rst close cycle, the control unit determines the force necessary to be applied with the electronic brake and the excessive
dip will be compensated when subsequent close cycles are performed.
2) The barrier is reopened by the automation system during a close cycle, even though there are no obstacles and the photocell beams are
not interrupted.
The chain height setting is too high. Reduce the setting with trimmer PM2.
