TROUBLESHOOTING
The gate will not move
• No programming performed
• One or more NC contacts open
• Burnt fuses
• Torque too low
• Photocells not aligned or disturbed
• Perform programming (page 32)
• Check all NC contacts (green LEDs must all be on)
• Check conditions of all fuses
• Enable the torque trimmer to increase it
• Align photocells and verify conditions
Led lamp on casing off
• No 230 V power
• 5 A line fuse burnt
• 630 mA fuse for 24 V burnt
• Unlocking handle not locked
• Check the line and all fuses
• The gate might have run into either gate stops.
Adjust the limit switch brackets (see page 25)
• Close and remove the key from the lock
Led lamp on casing flashing BLUE
• An obstacle or a possible friction have been
detected during the gate movement for 5
consecutive times
• Remove obstacles and give an opening/closing
command
• Remove possible causes of friction on the sliding
gate track/guides
• The gate might have run into either gate stops.
Adjust the limit switch brackets (see page 25)
Led lamp on casing alternatively
flashing BLUE-ORANGE
• Photocell malfunction on DSA control carried out
before movement
• Realign the photocells
• Disconnect power to photocells for a few
seconds
• Power supply for DSA photocells is to be
connected to the terminals 13-14
The gate starts moving, then it
stops or reverses
• Detects the continuous presence of an obstacle or
possible friction during movement
• Photocells not aligned
• Remove obstacles and give an opening/closing
command
• Enable the torque trimmer to increase it
• Realign the photocells
The led device on the protective casing is a fixed light blue when the automatism is working properly. It flashes or becomes orange in the
presence of any electrical system faults.
