contre les accidents !
Note
Le module ne contient pas de composants soumis à maintenance par
l'utilisateur. Pour l'autorisation d'un circuit de sécurité selon EN / IEC
60204-1, EN ISO / ISO 13850 il est impératif d'utiliser seulement les
circuits de sortie libres de potentiel entre les bornes 13-14, 23-24 et
33-34.
ATTENTION
RISQUES RÉSIDUELS (EN ISO / ISO 12100-1)
Le schéma de raccordement proposé ci-dessous a été vérifié et testé
avec le plus grand soin dans des conditions de mise en service. Des
risques subsistent si :
a) le schéma de câblage ci-dessous est modifié par changement des
connexions ou l'adjonction de composants lorsque ceux-ci ne sont
pas ou insuffisamment intégrés dans le circuit de sécurité.
b) l'utilisateur ne respecte pas les exigences des normes de sécurité
pour le service, le réglage et la maintenance de la machine. Il est
important de respecter strictement les échéances de contrôle et de
maintenance.
Le non-respect de cette directive peut entraîner des lésions
corporelles et/ou des dommages matériels.
ENGLISH
DANGER
HAZARDOUS VOLTAGE
Only trained professional electricians may install, startup, modify, and
retrofit this equipment!
Disconnect the device / system from all power sources prior to starting
any work!
If installation or system errors occur, line voltage may be present at the
control circuit in devices without DC isolation!
Observe all electrical safety regulations issued by the appropriate
technical authorities or the trade association. The safety function can
be lost if the device is not used for the intended purpose.
Opening the housing or any other manipulation will void the warranty.
Failure to follow this instruction will result in death or serious
injury.
CAUTION
UNINTENDEND USE
If the device has been subjected to improper or incorrect use it must no
longer be used, and the guarantee loses its validity.
Impermissible conditions include:
strong mechanical stress, for example through a fall, or voltages,
currents, temperatures or humidity outside of the specifications.
Before starting up your machine/plant for the first time, please be sure
to check all the safety functions according to valid regulations, and
observe the specified test cycles for safety equipment.
Failure to follow this instruction can result in injury or equipment
damage.

CAUTION
RISKS ON INSTALLATION
Perform the following precautionary steps prior to installation,
assembly, or disassembly:
1. Disconnect supply voltage to the equipment / system prior to starting
any work!
2. Lockout/tag the equipment / system to prevent accidental activation!
3. Confirm that no voltage is present!
4. Ground the phases and short to ground!
5. Protect against adjacent live components using guards and barriers!
6. The devices must be installed in a cabinet with a protection class of
at least IP 54.
Failure to follow this instruction can result in injury or equipment
damage.
CAUTION
LIMITED CONTACT PROTECTION
• Protection type according to EN / IEC 60529.
• Housing/terminals: IP 40 / IP 20.
• Finger-proof acc. to EN 50274.
Failure to follow this instruction can result in injury or equipment
damage.

Application
Safety systems are comprised of many components. No one safety
component will insure the safety of the system. The design of the
complete safety system should be considered before you begin. It is very
important to follow applicable safety standards when installing and wiring
these components.
The module HR1S-AK provides interruption of one or several circuits and
is designed to be integrated into the following applications:
• Monitoring of emergency stop circuits.
• Monitoring of limit switches on protective guards.
• Monitoring of short-circuit generating footmats or pressure sensitive
rails (in category 3).
• Monitoring the OSSD of type 4 safety lightcurtains with semiconductor
outputs according to EN / IEC 61496-1.
The module provides three safety outputs of stop category 0 (EN ISO /
ISO 13850, EN / IEC 60204-1) as well as one NC contact and four
semiconductor outputs for signalling purposes.
The module is designed for use with one or two input channels. Due to
the extended possibilities of fault detection and resulting increased safety
level we recommend the use of two input channels. In this operation
mode the connection cables are included in the monitoring and all initial
faults will be detected.
For information about wiring diagrams as well as the functional diagrams
for each individual safety function please refer to page 12/20 - 17/20.
An internal electronic fuse protects the module against destruction by
external short circuits (e. g., short circuits between the + and the - of the
input circuits). After elimination of the fault, the module is again operative
after a few seconds.
It is imperative that an external fuse be connected as shown on the
"WIRING DIAGRAM FOR MODULE HR1S-AK SAFETY RELAY".
