Instruction sheet – Safety limit switch with separate actuator
010 IST R 01 SC 1010 - 01
The COMEPI safety limit switches are devices designed and made in compliance
with the international IEC regulations and the EN European standards. They
can be used for monitoring guards on industrial machines and for building
safety systems in compliance with standard EN ISO 14119. Being a protection
equipment for operators, its incorrect installation or tampering can damage
people, even seriously.
The device installation must be carried out according to
the regulations in force by authorized staff only. Make sure the switch works
properly before starting the machine and periodically check the correct
operation of the equipment.
Installation precautions
Before starting the machine, check the proper operation of the safety system.
Periodically check the correct operation of the device.
The device installation must be carried out by authorized and qualified staff
only.
The device use must be limited to the applications meeting the regulations
requirements.
The device installation and the safety system design must be carried out only
by people knowing the regulations in force.
The device installation and the safety system design must be carried out in
compliance with the regulations in force.
In case of doubts or special applications, please contact COMEPI Technical
Support.
Do not install in dusty or dirty places.
During installation and operation, it is fundamental to prevent dust and dirt
from entering the opening when the start key is not inserted.
Before any painting operation, cover the opening and the identification label.
Do not install in places where there are flammable dusts or gases.
Do not install in places with strong vibrations; impacts and vibrations can
prevent the switch correct operation.
Use only proper actuators supplied by COMEPI, suitable for the model used;
otherwise safety could be void.
Install the actuator in a suitable way, so that it does not harm the operator
when the door is open.
If the microswitch is damaged or worn, replace the whole device to ensure
safety.
If the actuator is damaged or worn, replace it.
Replace the equipment after exceeding the mechanical durability limit.
During wiring, keep load under the value of the use category.
Check that safety contacts are connected to a protection fuse.
Technical data
Before reaching the switch contacts, make sure the device is not supplied with
power.
Tighten the screws with the specified tightening torques (0.5Nm plastic, 0.8Nm metal).
The device must not be disposed of following special procedures, just comply
with the regulations in force in the country where the device is used.
Use limits
Use the switch complying with the regulations in force within its operation
limits. The manufacturer is not to be held responsible for damages if: the device
was not used properly, instructions were not followed, assembly and
maintenance operations were carried out by unauthorized or unskilled staff.
This device complies with 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
Approvals
cULus according to standard UL508 – IMQ according to EN 60947-5-1 (for the
complete list of the certified products, please contact COMEPI Technical
Support).
Use and operation examples
This kind of device is typically used to monitor the safety guards on industrial
machines. When the guard is closed, the microswitch is in the normal operation
condition, while when the guard is open, the signal controlling the machine stop
due to dangerous situation is produced. A single device cannot be used to
ensure safety when the guard protects the perimeter of machines for which
dangerous conditions may last a certain time after generating the stop signal.
Moreover, this device cannot be used as emergency stop device. To test the
proper operation of the equipment, check the correct insertion of the actuator
into the head opening and close the guard starting the machine. When opening
the guard, the machine stop signal will have to be produced. The machine
restart must be impossible while the actuator is not inserted in the device
opening. The device must not be used as mechanical lock and it is necessary to
avoid actuator impacts on the head, due to misalignment of components.
Safety warnings
Safety switches protect operators. An incorrect installation as well as the
tampering of the device and of its safety system can cause even extremely
dangerous situations. Never bypass or tamper with the device. In order to avoid
any tampering attempt, it is advisable for the installer to mount the device in a
place that cannot be easily reached by unauthorized staff, even using physical
barriers or other means to make tampering difficult.
