MAINTENANCE AND DIAGNOSIS OF FAILURES

1

MAINTENANCE


Before carrying out
operation, disconnect the device from the
power supply.
O
If you have to dismount the operator from its
supports, first tighten the discharge screw in
order to prevent the hydraulic fluid from
leaking.

FAILURE DIAGNOSIS

Problem
The operator does not make any
movement when the opening or
closing transmitters are activated
By activating the opening or
closing controls, the operator is
enabled but the gate does not
move
The gate moves in an irregular
manner
Only for operators
mechanical slow down:
operator does not make a soft
stop (no mechanical slow down)
The gate cannot completely close
(or open)
any maintenance
Cause
Absence of system power voltage
Defective electrical installation
Defective control panel or control
devices
Defective capacitor
The assembly dimensions of the
supports have not been respected.
The screw for manual operation is
in unlock position
The operator is not horizontal
The piston rod does not reach the
with
end of travel
the
The photocell detects an obstacle
The resistance of the gate has
increased when closing (or when
opening)
The force of the operator during
closing (or opening) is too low
The assembly dimensions of the
supports have not been respected.
1 Regularly check installation in order to discover any
imbalance or signs of deterioration or wear. Do not
use the device if any repair or adjustment is
necessary.
2 Clean and lubricate the articulations of the gate, so
as not to increase the effort of the operator.
3 Check that the transmitters and photocells, as well
as their installation, have not suffered any damage
from the weather or external agents.
Solution
Re-establish the power supply
voltage
Check that the installation does
not present any short-circuits or
cut-off points
Check these elements, seeing their
respective manuals
Check the state of the capacitor
Dismount the supports and then
put them back in place, respecting
the assembly dimensions
Using the corresponding wrench,
position the screw in "automatic
operation lock" position.
Dismount the supports and then
put them back in place, respecting
the height difference of 19 mm
Regulate the ball bearing joint to
ensure it reaches the end of travel
If this is not sufficient, move the
front support
Eliminate the obstacle and try
again
Check the moving parts of the gate
and eliminate the resistance
Use the opening and closing force
adjustment screws to increase the
force when opening and closing
Dismount the supports and then
put them back in place, respecting
the assembly dimensions
