DDC 16 – Electromagnetic switches and separate actuator with RFID coding series FEP-RFID
Limits of use
Use the switch in compliance with the standards in force, according to the
instructions and using it according to its limits of operation. In case of improper
use, non-compliance with the instructions, assembly and maintenance carried
out by unauthorized or unskilled staff and failure to perform the functional
tests, the manufacturer is not liable at all. Do not use the device separately to
ensure safety in those areas where the operator can enter with all his body
within the perimeter. Any unintentional closing of the protection behind the
operator could cause dangerous situations for the operator himself. Do not use
in places with continuous changes in temperature, that could cause
condensation inside the device. Do not install in areas with dust or dirt that
could compromise the device operation. Do not install in places with powders
or flammable gases. Do not use outside the temperature limits expected for
operation. Do not use in places where ice sleeves can form on the device or on
the actuator. Do not use with very corrosive chemical agents, that can damage
the internal mechanisms and the device gaskets.
The device complies with the requirements of the following Directives:
Low Voltage Directive 2014/35/EU
According to standard EN 60947-5-1
Machinery Directive 2006/42/EC
According to standard EN ISO 14119
Directive RoHS 2002/95/EC
Certifications
cULus according to standard UL508 – CB according to EN 60947-5-1 – FCC ID
Number 2AP8TCMP9LRF (for the whole list of certified products contact

Examples of application and operation
This kind of device is usually used to ensure the operator’s safety while using
machines where a dangerous condition can continue even after the machine
is stopped, for instance due to the inertia of mechanical parts that are
moving, or to the presence of warmed up or pressurized parts. If this device is
used separately, it is not suitable for machines where an operator can enter
physically an enclosed area, since the enclosure could close accidentally after
the operator has entered it. To test the correct device operation, check the
right insertion of the actuator into the head slot and close the protection by
starting the machine. In these conditions it must be impossible to open the
protection. On the contrary when the machine is stopped and the protection
is disabled the machine must not start.
Safety warnings
Safety switches protect operators. Any unsuitable installation, as well as the
device tampering and the tampering of the safety system connected to it, can
cause serious dangerous situations. The device must in no way be bypassed or
tampered with. To prevent any easy tampering the installer should assemble
the device in a place difficult to be reached by unauthorized staff, using if
necessary physical obstacles and measures to make it difficult to tamper with
the device.
