the opening movements when a user is present, either using the push-button station or
the radio control (when operating via 2-button radio control the button corresponding to
the closing movement is disabled and when operating via 3-button radio control the clos-
ing movement and Stop buttons are disabled). We recommend a qualified technician is
contacted immediately in order to resolve the problem. Once the correct operating condi-
tions are restored the control unit may be switched on again. The error status is reset and
the control unit is ready to operate normally.
HARDWARE DIAGNOSTICS:
PUL command test:
The control unit is fitted with a Red LED for every low voltage PUL command so that its
status may be monitored quickly.
Operation principle: LED on = input closed, LED off = input open.
DS1 safety device test:
The control unit is fitted with a Red LED which corresponds to the low voltage DS1 safe-
ty device input, so that its status may be monitored quickly. Operation principle: LED on
= input closed, LED off = input open.
DS2 - DS3 safety device test:
The control unit is fitted with two indicator LEDs (Red and Green) which correspond to the
low voltage DS2 and DS3 safety device inputs, so that their status may be monitored
quickly. Operation principle: Red LED illuminated input closed, Green LED illuminated
input closed with balanced device (8.2K ohm type), Red and Green LEDs switched off
input open.

OTES FOR THE NSTALLER
The control unit was designed to facilitate the task of automating closure while respect-
ing the guidelines set out in the Machines Directive and the CPD.
The safety of the final installation site and adherence to all current legislation is, never-
theless, the responsibility of the individual assembling the various parts to construct a
complete closure device.
To facilitate the fulfilment of the obligations relating to regulations (EN 12453 - EN 12445
- EN 60335-2-103), the control unit is designed to operate in conjunction with various
safety devices, namely:
• Sensitive tubes for fixing to cabinet edges (to enable force limitation), monitor in com-
pliance with category 2 of EN 954-1, according to provisions made in point 5.1.1.6 of
EN12453; after installation the effective force limitation must be checked using the
methods detailed in regulations EN 12453, EN 12445 and EN 60335-2-103.
• Photoelectric cells monitored in compliance with category 2 of EN 954-1, according
to the provisions made by point 5.1.1.6 of EN 12453.
It is, however, the installer's responsibility to ensure that the minimum protection level
of the main closure edge is achieved.
By programming the control unit suitably and installing the safety devices correctly, the
installer is able to guarantee the minimum level of protection in accordance with the
provisions made in paragraph 5.5 of standard EN 12453.
If a safety device fault is detected (5.1.1.6 EN 12453) the control unit automatically
changes to a non self-holding control. In accordance with points 5.1.1.4 of regulation
EN 12453 and 4.1.1.4 of EN 12445, it is necessary to check that the primary edge
speed is < 0.5 m/s and that the stopping distances respect the values indicated by the
legislation (after the command is sent the stopping distance should not be > 50 mm for
spaces < 500 mm and > 100 mm for spaces > 100 mm).
In accordance with point 4.1.2 of regulation EN 12445 it is necessary to check that:
- the door is not capable of lifting a mass of 20 kg (or 40 kg for doors installed in areas
which are not accessible to the public) from its closed position. The mass must be
attached to the door at the least favourable position. The maximum size of the mass
should be 300 mm in any direction, or
- when the door is capable of lifting a mass of 20 kg (or 40 kg), it must stop before the
lifted body reaches the lintel or other fixed parts of the building.
The regulation enables an alternative safeguard against the risk of lifting to be achieved
through the installation of closure systems which are not fitted with hooks, openings or
protruding parts where an individual may become entangled, so that it is impossible for
anyone to be pushed or lifted by the door.
Do not use the control unit in conjunction with exit door sites or emergency exit routes.
