5 DIRECTIONS FOR CORRECT DEVICE USE
5.1 Installation
Warning: The installation must exclusively be carried out by qualifi ed
personnel. The OS1 and OS2 safe outputs of the device must be connected
to a safety module (or safety PLC) for their supervision. The O3 and O4 signalling
outputs are not safe outputs and cannot be used individually in a safety circuit to
determine the safe guard-closed status.
• Do not deform or modify the device for any reason whatsoever.
• Do not exceed the tightening torques specifi ed in the present manual.
• The device carries out an operator protection function. Any inadequate installation
or tampering can cause people serious injuries and even death.
• These devices must neither be avoided (for example by bridging the contacts), nor
removed, nor turned or made ineffi cient in any other way.
• If the machine where the device is installed is used for a purpose other than that
specifi ed by the producer, the switch may not provide the operator with effi cient
protection.
• Before commissioning the machine and also periodically, check for correct switch-
ing of the outputs and correct operation of the system comprising the device and
associated safety module.
• The safety category of the system comprising the safety switch also depends on
external devices and their connection.
device.
• Before installation, make sure that each part of the device is intact.
• Before installation, ensure that the connection cables are not powered.
• Avoid excessive bending of connection cables in order to prevent any short circuits
or power failures.
• Do not paint or varnish the device.
device.
• Do not perforate the device; to insert electrical cables only use one of the three
M20x1.5 threaded cable inlets found in the device. Do not use the device as a sup-
a
port or rest for other structures, such as raceways sliding guides or similar.
• Before setting at work, make sure that the entire machine or system complies with
a
all applicable standards and EMC directive requirements.
• Do not apply excessive force on the device, after the actuator has been fully in-
a
serted.
• The switch fi tting surface must always be smooth and clean.
• Should the installer be unable to fully understand the documentation, the product
must not be installed and the necessary assistance may be requested (See para-
graph SUPPORT).
• When the device is installed on a mobile frame and the actuator is installed on a
mobile door, ensure that the device cannot be damaged by simultaneous opening
of the frame and the door.
• After installation, check for correct operation of the auxiliary release (if present) and
the anti-panic release button (if present).
• Always keep the present operation directions enclosed with the manual of the ma-
chine to which the device is fi tted.
• The present operation directions must be kept in such a way as to be readily avail-
able during the entire period when the device is used.
5.2 Not to be used in the following types of environment
• An environment where continuous temperature changes cause condensation in-
side the device.
• An environment where the application causes the device to be subject to strong
impact or vibration.
• An environment where explosive or fl ammable gases are present.
• An environment where the device may become coated with ice.
• An environment containing strongly aggressive chemicals, where the products
coming into contact with the device may impair its physical or functional integrity.
• An environment where contaminated agents can get in the hole found in the switch
head and be deposited inside, which can lead to sealing gasket damage, can stop
the fi xing pin from sliding or damage it.
5.3 Mechanical stop
• Even if the switch is provided with a rubber bumper positioned between the actua-
tor and the switch, the door must always be provided with an independent end-limit
mechanical stop on closing. All that to protect the device from being knocked when
the door is slammed hard.
• Do not use the switch as a mechanical door stop.
5.4 Impacts, vibrations and wear
• In case of any damage or wear, the entire device must be replaced.
• Avoid any collision with the device. Impacts and excessive vibrations may fail to
guarantee correct device operation.
