the moveable barrier.
Faults Possible
cause
Solution
The barrier does not perform the
open/close commands
No electrical power
Check for the presence of electrical energy.
The ON/OFF switch is OFF or has been
triggered due to a fault
Check the conditions of the switch and turn ON
again if necessary
The photocells are not in the light or a
foreign element is present
Check the photocells
Opening of the automatism-barrier
connection through the emergency
manoeuvre
Close the connection using the designated key
The end run is not closed
Check the action and the continuity of the end
run contacts
The barrier goes up and then remains
blocked in that position
The spring is too taut and the
automatism cannot overcome the weight
of the barrier and the return action of the
spring
Adjust spring calibration
The arm used is too long or too heavy
Adjust spring calibration
When the barrier comes down, it hits
the fixed support at the end
Mechanical end run not positioned
correctly, spring not preloaded enough
Adjust the calibration of the end run and the
spring preload
