5 SPARE PARTS LIST
The list of spare parts that can be ordered (Page 35) is a
detailed list that accompanies the exploded view of the product
and must be used to order spare parts.
The following data must always be provided when ordering
spare parts:

6 COMPLETE CLOSING ASSEMBLY

This chapter illustrates the typical installation of a comple-
te automatism for the purpose of informing and assisting the
installer in the selection of the various parts to be used in com-
pliance with Machinery Directive (2006/42/CE) and European
Safety Standards (EN 12453 - EN 12445) for gate installation.
The data provided in this chapter are neither complete nor
exhaustive, and DEA System declines all liability for any errors,
omissions or inaccuracies that may occur.
6.1 Minimum level of protection provided by the
safety edge
Among the most serious risks to be considered for the auto-
mation of a swing gate is the risk of crushing between two leafs or
between one leaf and its stop in closing position. Regulations pre-
scribe the adoption of a proper control against such risk (e.g. limit
of forces, presence detection, safety distances) depending on the
use foreseen for the gate (see the "OPERATING CONTROL" table)
6.2

Crushing in the opening area

The risk of crushing can also arise in the area between the
gate being opened and the wall or other construction behind
it. F8 on Page 40 provides the measurements that must be re-
spected whenever measures are not taken to limit the impact
force or whenever presence detection systems are not used.
6.3

Impact in the opening/closing area

In order to avoid crushing by the gate wing in the closing
area, install a pair of photocells (A) (recommended height: 500
mm) in order to detect the presence of the test parallelepiped (B)
(height: 700 mm) positioned as shown in F9 on Page 40.
Note. The presence detection test sample is a parallelepiped
with 3 sides with light-coloured reflecting surfaces and 3 sides
with dark-coloured, opaque surfaces.

MALFUNCTION
When the opening command is given, the leaf fails
to move and the operator's electric motor fails to
start
When the opening command is given, the motor
starts but the leaf fails to move
The operator jerks during movement
L O O K
In order to further reduce the risk of impact with the gate
wing in the opening area, an extra pair of photocells (C) (re-
commended height: 500 mm) can be installed for the detection
of the presence of the test parallelepiped (D) (height: 700 mm)
positioned as shown in F9 on Page 40.
"TROUBLE-SHOOTING" table
The operator is not receiving correct power supply. Check all connec-
tions, fuses, and the power supply cable conditions and replace or
repair if necessary
Whenever the operator is equipped with an unlocking device, make
sure that it is closed (see F4, Page 40)
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
If the leaf does not move freely, release the ram and readjust the
rotation points
The power of the gear motor may be insufficient for the characteristi-
cs of the gate's wing; check the choice of model whenever required
The operator's front and rear attachments bend or are not fastened
correctly. Repair or replace
