6.2 Unlocking and Manual operation
In the event of malfunctions or simple power failure, release the motor (Pic. 9) and perform the operation manually.
The knowledge of the unlocking operation is very important, because in times of emergency the lack of timeliness in acting on such
a device can be dangerous.
WARNING The ef fi cancy and safety of manual operation of the automation is guaranteed by DEA System only if the installation has
been installed correctly and with original accessories.
7 MAINTENANCE
Good preventive maintenance and regular inspection ensure
long working life. In the table below you will fi nd a listo f inspections/
maintenance operations to be programmed and executed periodi-
cally.
Consult the TROUBLE-SHOOTING” table whenever anomalies are
observed in order to fi nd the solution to the problem and contact
DEA System directly whenever the solution required is not provided.
INTERVENTION TYPE PERIODICITY
cleaning of external surfaces 6 months
checking of screw tightening 6 months
checking of release mechanism operation 6 months
greasing of articulated joint 1 year
Checking the oil level 1 year
Replacing the oil 3 years
7.1 Checking and replacing the oil (Pic. 12)
Replace the oil provided by DEA System after three years of use with one of the same type (see the “Technical data” table). Should
inspections reveal an insuf fi cient oil level, it means that there must be a leakage. Therefore, check all the closing systems to fi nd the leak
and solve it or request spare parts and/or support from DEA System.
To replace the oil, open the release cover and release the motor. Next, remove the handle, remove OLI from its attachments and turn it
upside down until the oil is fully drained. Top up to its regular level (Fig. 12). Now, assemble the release handle again, taking care that the
arrow is set to the OPEN position, and install the motor in the system.
WARNING If you remove the OR gasket from the handle unit, water may enter the oil tank causing malfunction and damage the product.
Always make sure it is installed.
WARNING Water leaks – or of other substances – may occur during adjustment operations. This may damage the pump. Pay special
attention to foreign bodies in the proximity during adjustment operations.
TROUBLE-SHOOTING
Description Possible solutions
When the opening command is given, the leaf fails to move
and the operator’s electric motor fails to start. The operator is not receiving correct power supply. Check all connections, fuses, and the
power supply cable conditions and replace or repair if necessary.
When the opening command is given, the motor starts but
the leaf fails to move.
Always make sure that the operator is closed (if available) (Fig. 9) and adjust the opening
and closing pressure.
Make sure that the electronic device for electric power adjustment is in good condition.
If the piston remains at the complete end of its stroke when the gate is closed, review the
assembly procedure.
The operator jerks when in motion. It is noisy; it stops
halfway and fails to start again.
Possible presence of air inside the cylinder. Release the operator from the front attachment
and carry out a few load-free trial manoeuvres before restoring the attachment.
Insuf fi cient amount of oil inside the cylinder. Restore the normal level of oil (Fig. 12) and
bleed off the air carrying out a few load-free trial manoeuvres.
The operator’s front and rear attachments bend or are not fastened correctly. Repair or
replace.
