 Safety Limit Switches
Safety Limit Switches with separate actuator - Description
Applications
Easy to use, the limit switches with small latch (key) offer specific qualities:
• Capability for strong current switching (conventional thermal current 10 A).
• Opening guaranteed of the "N.C." contact(s) when the small latch is withdrawn from the limit switch.
• Contact blocks with dependent action and positive opening operation of the "N.C." normally closed contact(s) (symbol ).
• Electrically separated contacts.
• Precision on operation positions (consistency).
• Immunity to electromagnetic disturbances.
These specific features make the limit switches ideal for monitoring and protection of industrial machines without inertia in which downtime is
less than access time to the dangerous area. Use on sliding or pivoting protectors (covers, cases, doors, grids, etc.).
• They contribute to protection of operators working on dangerous machines, by opening the control circuit. Withdrawal of the small latch (key) by opening the
mobile protector causes immediate stopping of the machine drive.
• They comply with the requirements of European Directives (Low Voltage and Machines Directive) and are conform to European and international standards.
Description
Safety limit switches with small latch (key) of SP/SDP/SBP/SFP series are made of fibre-glass reinforced UL-V0 thermoplastic material, and they offer double
insulation and a degree of protection IP65. Safety limit switches of SM/SDM series are made of zinc alloy (zamack) and have a degree of protection IP66. Safety
limit switches SBM/SCM are realized in aluminium material and have a degree of protection IP66.
All models are equipped with 1NO+1NC, 2NC, 1NO+2NC, 2NO+1NC or 3NC contact blocks with positive opening operation of the "N.C." contact(s).

 Electromagnetic Safety Devices
Electromagnetic safety devices with separate actuator - Description
Applications
This device is useful for guarantee the safety of the operator in case of machines where the hazardous conditions remains for a while time after the generation
of the stop signal, because of the mechanical inertia of moving parts, components under pressure or with high temperatures. This device, when used individually,
is not suitable for applications in machines where the operator can enter inside the protected area with his whole body, because of the possibility of accidental
closing of the protection fences after the operator entry. In order to test the proper operations, verify the correct insertion of the actuator in the operating head
and start the machine by closing the protection. In this conditions must be impossible to open the protection. With the machine stopped and disconnected pro-
tection, must be impossible to start the machine.

Safety warnings
Safety switches perform a human protection function. The wrong installation can cause serious danger situations, as well as the manumission of the device and
of the entire safety system. The device must never be evaded or manumitted in every way. To prevent easy tampering, we recommend to install the device in a
place difficult to access by unauthorized personnel, by using physical impediments or tricks to make any tampering more difficult.

Safety hinges - Description
Applications
Within the range of safety devices, Comepi has created a new hinge with multiple integrated circuit which can suit all applications where high security is combined
with a modern and sophisticate design. Thanks to its small sizes and numerous mounting options and connection (cable/connectors), the device is easily installed
on most common aluminium profiles (minimum width 30 mm.). Its installation is also facilitated by the integration of a safety switch integrated into a single body,
thus avoiding the need to separately install a mechanical hinge and a safety switch connected via a special pin.
The use of stainless steel components and the degree of protection IP67 permit the hinge to be subjected to frequent washing and to be used in environments
where cleanliness and hygiene require maximum attention. The Comepi hinge was developed and manufactured according to the rules set out in IEC international
publications and to applicable EN European Standards; the use of a redundant system and a proper configuration allows to obtain a safety system of machinery up
to SIL 3 or PLe according to EN ISO 13849-1.

Description
Both the self-extinguishing body of the hinge and the rotation pin are made of technopolymer with high-rigidity capable of resisting to solvents, oils, greases and
various chemical agents. The internal switch is composed of 4 slow action double break contacts. The positive opening (according to IEC EN 60947-5-1) is guaranteed
on all NC contacts. All the circuits have a low contact resistance thanks to the self-cleaning action of the silver pastes.
Each hinge is supplied with the following kit:
- n°4 technopolymer covers (to avoid free access to screws):
- n°4 technopolymer bushings (for hexagon socket or nut M6).
- n°2 thermoplastic elastomer safety plugs to guarantee IP67 protection degree.

Operating diagrams
X22C X13C

As shown in the travel diagrams, the angle of action is set at the factory to 5° (opening of the NC contacts, to be verified according to EN294).
This angle and consequently also angles relating to the closure of the NO contact and positive opening of the NC contacts can be adjusted by the installer; in the
case of doors of considerable size, the operating angle can be reduced up to 1° operating with a screwdriver on the adjustment screw. The degree of protection IP67
is then secured by inserting the appropriate safety plug (not removable) in the adjustment hole.
It is recommended to verify the correct operation of the device before starting up the machine and we suggest to repeat the test periodically.

Special executions on request

• Operating angle of the hinge other than from 0° to 180°, every 15°, where the system frame/door requires a special execution.
• NC and NO contact blocks setting (up to 4 NC).
• NO and NC ovelapping contacts.

Implementation
Determination of maximum applicable load
For SPH1 hinges with built-in safety multiple switch, the reference value supplied is the max limit static load
(Sa, Sr, S90), since these hinges can be used as safety devices.
Above this value, the material may break, thus prejudicing the hinge functionality. Obviously a suitable factor,
according to the importance and safety level of the specific application, must be applied to this value. The
load values shown in the tables of the different hinges are the result of tests carried out in our laboratories
under controlled temperature and humidity (23°C-50% R.H.), under given conditions of use and for a limited
period of time.

Example of suitability check

P weight of the door [N] The technical designer must use suitable safety fac-
P1 additional extra load [N] tors (k) according to the type of application and fun-
W width of the door ction of the SPH1 hinge.
D distance [metres] between the centre of gravity
of the door and the hinge axis. In normal con-
ditions D = W/2
D1 distance [metres] between the hinge axis and
the additional extra load application point
N number of hinges
k safety factor
dT sum of the distances [metres] of all the hinges
from the hinge of reference (d = d + d + ... +
dn). In case of only two hinge assembled, d is
simply the distance between them

The examples shown here must be considered only

Conditions to be checked in order to ensure a correct as explanatory, since they are not applicable to all
functioning with two or more hinges the different applications, conditions of use, ways of
assembly which can actually take place.
In practice, the technical designer, after applying a
suitable safety factor (k) must also test the chosen
product to check its suitability.

 Safety Limit Switches
Hinge mount Safety Limit Switches - Description
Applications
Easy to use, the limit switches with rotative axis or lever offer specific qualities:
• Capability for strong current switching (conventional thermal current 10 A).
• Opening of the "N.C." contact(s) for a very small rotation angle: 12°.
• Contact blocks with dependent action and positive opening operation of the "N.C." normally closed contact(s) (symbol ).
• Electrically separated contacts.
• Precision on operating positions (consistency).
• Immunity to electromagnetic disturbances.
These specific features make the limit switches ideal for monitoring and protection of light industrial machines without inertia equipped with
angular movement protectors (doors, hinged grids, rotative covers or cases, etc.). Detection by the rotative axis or by means of a lever.
• Opening of the mobile protector guarantees operator protection by immediately stopping the machine drive.
• These switches are suitable for conformity of the existing installed machine base, as they can be mounted on protection devices already installed.
• They comply with the requirements of European Directives (Low Voltage and Machines Directive) and are conform to European and international standards.

 Safety Limit Switches
Safety Limit Switches with rope - Description
Applications
Easy to use, the limit switches for safety applications with rope for simple and emergency stop offer specific qualities:
• Capability for strong current switching (conventional thermal current 10 A).
• Contact blocks with positive opening operation of the "N.C." normally closed contact(s) (symbol ).
• Electrically separated contacts.
• Precision on operating positions (consistency).
• Immunity to electromagnetic disturbances.
The use of the Comepi pull wire safety switches allows you to create perimeter protections of the machines, thus reducing the need to install
sever emergency stop stations in different points of the machine. They comply with the requirements of European Directives (Low Voltage and Machines
Directive) and are conform to European and international standards.

Description
SM/SDM series are made of zinc alloy (zamack). SBM/SCM series are realized in aluminium material, therefore they are mechanically more resistant and three
times lighter than the ones in zinc alloy. All metal limit switches have a degree of protection IP66.

Installation instructions
In order to obtain the correct operation
of the device, please follow the following
instructions.
1. Install the switch and secure the fixed
end of the rope. Apply tension to the ex-
tent the green O-ring is visible and the
bottom is flush with the end of the red
housing. (Fig. 1).

2. Pull the reset pommel in order to close the safety contacts

of the limit switch.
3. The contacts inside the limit switch will change their po-
sition whenever the rope is pulled or loose its tension.
4. Check the correct operation of the rope switch before you
start the machine and periodically.
Performing the role of worker protection, improper installation
or tampering with safety devices can cause serious injury to
persons.
The installation must therefore be performed in accordance
with local legislation and only by authorized personnel.

 Safety Limit Switches
Safety Limit Switches with reset - Description
Applications
Easy to use, the limit switches for safety applications with latch and manual reset offer specific qualities:
• Visible operation (fault memorisation).
• Capability for strong current switching (conventional thermal current 10 A).
• Contact blocks with positive opening operation of the "N.C." normally closed contact(s) (symbol ).
• Electrically separated contacts.
• Precision on operating positions (consistency).
• Immunity to electromagnetic disturbances.
These specific features make the limit switches ideal for detection and monitoring of faults in hoisting machines, electric lifts, freight elevators,
escalators, conveyor belts, etc. They comply with the requirements of European Directives (Low Voltage and Machines Directives) and are conform to European
and international standards.

Description
Limit switches with latch and manual reset are equipped with operating heads with plunger, roller plunger or roller lever, used to detect rectilinear or angular mo-
vements. AP/DP series are made of fibre-glass reinforced UL-V0 thermoplastic material, they offer double insulation and a degree of protection IP65.
AM/DM series are made of zinc alloy (zamack) and have a degree of protection IP66. Limit switches with latch and manual reset are equipped with 1NO+1NC, 2NC,
1NO+2NC, 2NO+1NC or 3NC contact blocks with positive opening operation of the "N.C." contact(s). After actuating the control device and overshooting the latching
point, the N.C. safety contact(s) remain in the open position. Return to the initial operating state takes place by voluntary action on the reset button.

Casing A variety of operating heads:

• 30 mm. width with standardized dimensions acc. to EN 50047 • Metal plunger

General Technical Data, Specifications, Directives and Standards
The Comepi products listed in this catalogue are developed and manufactured according to the rules set out in IEC international publications and EN European
standard.

Specifications
• International Specifications
The International Electrotechnical Commission, IEC, which is part of the International Standards Organization, ISO, publishes IEC publications which act as a basis
for the world market.
• European Specifications
The European Committee for Electrotechnical Standardisation (CENELEC) publishes EN standards for low voltage industrial apparatus.
These European standards differ very little from IEC international standards and use a similar numbering system. The same is true of national standards. Contra-
dicting national standards are withdrawn.
• Harmonised European Specifications
The European Committees for Standardisation (CEN and CENELEC) publish EN standards relating to safety of machinery.
• Specifications in Canada and the USA
These are equivalent, but differ markedly from IEC, UTE, VDE and BS specifications.
UL Underwriters Laboratories (USA)
CSA Canadian Standards Association (Canada)

Remark concerning the label issued by the UL (USA). Two levels of acceptance between devices must be distinguished.
“Recognized” Authorised to be included in equipment, if the equipment in question has been entirely mounted and wired by qualified personnel. They are not
valid for use as “General purpose products” as their possibilities are limited.
They bear the mark:
“Listed” Authorised to be included in equipment and for separate sale are “General purpose products” components in the USA.
They bear the mark:

European Directives
The guarantee of free movement of goods within the European Community assumes elimination of any regulatory differences between the member states. European
Directives set up common rules that are included in the legislation of each state while contracditory regulations are cancelled.

There are three main directives:

• Low Voltage Directive 2014/35/UE concerning electrical equipment from 50 to 1000 V a.c. and from 75 to 1500 V d.c.
This specifies that compliance with the requirements that is sets out is acquired once the equipment conforms to the standards harmonised at European level:
EN 60947-1 and EN-60947-5-1 for limit switches.
• Machines Directives - 2006/42/CE defining main safety and health requirements concerning design and manufacture of the machines and other equipment
including safety components in European Union countries.
• Electro
megnetic Compatibility Directive 2014/30/UE concerning all electrical devices likely to create electromagnetic disturbances.

Signification of CE marking:
CE marking must not be confused with a quality label.
CE marking placed on a product is proof of conformity with the European Devices concerning the product.
CE marking is part of an administrative procedure and guarantees free movement of the product within the European Community.

Double Insulation
Class II materials, according to IEC 536, are designed with double insulation. This measure consists in doubling the functional insulation with an additional layer of
insulation so as to eliminate the risk of electric shock and thus not having to protect elsewhere. No conductive part of "double insulated" material should be
connected to a protective conductor.

Positive Opening Operation

A control switch, with one or more break-contact elements, has a positive opening operation when the switch actuator ensures full contact opening of the break-
contact. For the part of travel that separates the contacts, there must be a positive drive, with no resilient member (e.g. springs), between the moving contacts and
the point of the actuator to which the actuating force is applied.
The positive opening operation does not deal with N.O. contacts.
Control switches with positive opening operation may be provided with either snap action or slow action contact elements. To use several contacts on the same
control switch with positive opening operation, they must be electrically separated from each other, if not, only one may be used.
Every control switch with positive opening operation must be indelibly marked on the outside with the symbol: .

Snap Action
Snap action contacts are characterised by a release position that is distinct from the operating position (differential travel). Snap breaking of moving contacts is
independent of the switch actuator's speed and contributes to regular electric performance even for slow switch actuator speeds.

State of rest Contact change Positive opening

Slow Action
Slow action contacts are characterised by a release position that is the same as the operating position. The switch actuator's speed directly conditions the travel
speed of contacts.

State of rest Completely closed

Contact shape according to IEC 947-5-1.

Change-over contact elements with 4 terminals must be indelibly marked with the corresponding Za or Zb symbol as in the diagrams below.

Contacts with the same polarity The 2 moving contacts are electrically separated

Utilization Category
AC-15: switching of electromagnetic loads of electromagnets using an alternating current (⬎72 VA).
DC-13: switching of electromagnets using a direct current.

Terminals
Limit switches with metal casings must have a terminal, for a protective conductor, that is placed inside the casing very close to the cable inlet and must be indelibly
marked.

Minimum Actuation Force/Torque

The minimum amount of force/torque that is to be applied to the switch actuator to produce a change in contact position.

Minimum Force/Torque to achieve Positive Opening Operation

The minimum amount of force/torque that is to be applied to the switch actuator to ensure positive opening operation of the N.C. contact.
