HR1S-AC SAFETY RELAY MODULE OPERATING INSTRUCTIONS
HR1S-AC SAFETY RELAY MODULE OPERATING INSTRUCTIONS
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. L'utilisation du circuit de signalisation sans contact entre
les bornes Y43-Y44 est seulement admissible pour des fonctions n'étant
pas liées à la sécurité.
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'ajout 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.

Description of Device and Function
The supply voltage, as marked on the device nameplate, is applied to the
N.C. contacts of the EMERGENCY STOP button(s) to A1/A2 (see wiring
diagram). The N.C. contacts from each of the devices connected to
safety outputs 13-14, 23-24 and 33-34 must be wired in the feedback
circuit between terminals Y1 and Y2, in series with the START button.
This assures that the device can only be started if these external
contactors have dropped out after a preceding EMERGENCY STOP
command.
If the EMERGENCY STOP button is deactivated the LED "A1/A2" is lit.
The actuation of the START button energizes the internal relays K1 and
K2. The three safety outputs (13-14, 23-24 and 33-34) and the transistor
output Y43-Y44 are switched. In this state of operation, both LEDs "A1/
A2" and "K1/K2" are lit. The actuation of the EMERGENCY STOP
button(s) instantaneously opens the output contacts and the two LEDs
will go out.
Proper Use
The device is for monitoring sensors (e.g. emergency stop buttons,
position switches) that are used as part of the safety equipment of
machines for the purpose of protecting people, material and machinery.
Note
• The performance level and safety category in accordance with
EN ISO / ISO 13849-1 depends on the external wiring, the application
case, the choice of control station and how this is physically arranged
on the machine.
• The user must carry out a risk assessment in accordance with
EN ISO / ISO 14121-1.
• The entire system/machine must undergo validation in accordance
with the applicable standards on the basis of this.
