TROUBLESHOOTING GUIDE
PROBLEM
CAUSE
SOLUTION (to be applied only by qualified personnel, i.e. the Installer)
Power loss.
• Check the operator terminal blocks on the control unit for power supply
presence.
• Check the integrity of the operator supply cable and eventually replace it.
Fuse blown.
• Replace the fuse.
The operator
doesn't work.
Thermal protection is active. • Leave the operator stopped for at least 5 minutes; try a new manoeuvre when
it gets cooler.
With CR/62:
the impact control system
detected an obstacle.
• Switch the power off, manually unlock the release mechanism and eventually
remove any obstacle. Then relock the release mechanism.
• Repeat the leaf movement automatic learning procedure, or set more
appropriate values to parameters regulating operator strength and impact
sensitivity.
• Impact control can be set less sensitive or can be deactivated completely (see
CR/62 instruction manual). In this case other safety precautions must be taken
(for example a safety edge) in compliance with the laws in force.
ATTENTION!:
Any modification must be taken by qualified personnel only,
since
you, as the Installer, are responsible of the
installation and of its safe functioning
.
Wrong end limit setting.
• Check and set the positions of the end stop sliding plates and their action on
the actuator spring.
The leaf
doesn't
complete its
travel.
Wrong operator positioning. • Check the distance between the rear side of the operator and the sliding plates
to be between 25 and 35mm.
With CR/62:
decelerated manoeuvre after
a power loss.
• When the power returns, the leaf can be at half path. Next command will
cause a decelerated realignment to an end limit switch. Next manoeuvres will
be regular.
The leaf
moves slowly
even outside
the
deceleration
zones.
With CR/62:
decelerated manoeuvre after
an impact or after the
activation of the safety edge.
• Manoeuvres after an impact or after the safety edge intervention will be
performed as decelerated realignments to an end limit switch. Next
manoeuvres will be regular.
Starting a
manoeuvre,
the leaf
moves with
difficulty.
The operator start capacitor
is exhausted.
• Measure the capacitance of the capacitor and eventually replace it.
The leaf is
blocked
against the
mechanic
stop.
Sliding plates setting is
incorrect.
• Remove the operator plastic band from the lower part of the unit.
• Unscrew the nuts on the J-bolts completely and take off the washers.
• Slip off the operator from its position on the base plate to release the pinion
from the rack.
• Manually move the leaf far from the mechanic stop.
• Unlock the operator pushing down the release flap.
• Reposition the operator on the base plate.
•
Reposition the sliding plates accurately (follow the given procedure).
• Put the plastic band back in place and lock the operator raising the release
flap.
• Repeat the leaf movement automatic learning procedure.
Unreliable connection of the
antenna.
Check the correct installation of the antenna cable at the terminal blocks of both
the control unit and the flashing light.
Radio
coverage of
remote
controls is
reduced.
External antenna needed.
To obtain the maximum radio coverage, disconnect the antenna inside the
flashing light and replace it with the optional external antenna OG/50 (SERAI
code 25.50).
