2 On Safety
This chapter deals with your own safety and the safety of the equipment users.
bPlease read this chapter carefully before working with the i11S or with the
machine protected by the i11S.
The national/international rules and regulations apply to the installation, commission‐
ing, use and periodic technical inspections of the safety switches, in particular
•the machinery directive,
•the safety regulations as well as
•the work safety regulations/ safety rules.
2.1 Qualified safety personnel
The i11S safety switch must be mounted, installed and commissioned only by qualified
safety personnel. Qualified safety personnel are defined as persons who
•have undergone the appropriate technical training
and
•have been instructed by the responsible machine owner in the operation of the
machine and the current valid safety guidelines
and
•who have access to these operating instructions.
2.2 Applications
Safety switches of the i11S series are electromagnetic switching devices. They lock
guards (without locking device) so that
•the dangerous state of the machine can only be switched on when the protective
device is closed and locked,
•a STOP command is triggered if the protective device is opened with the machine
running.
For the control this means that
•starting is only possible when the protective device is in the closed position and
the dangerous motion should cease before opening the protective device.
Prior to the use of safety switches, a risk assessment must be performed on the
machine.
Important:
The user is responsible for the safe integration of the safety switch in a safe overall
system. For this purpose the overall system must be validated, e.g. in accordance with
EN ISO 13849-2.
If the safety switches are connected in series the Performance Level (PL) may be
reduced due to reduced fault detection, depending on the application (ISO/TR 24119).
2.3 Correct use
The i11S safety switch must be used only as defined in section 2.2 “Applications of
the safety switches”. The safety switch must be used only on the machine where it has
been mounted, installed and initialized by qualified safety personnel in accordance with
these operating instructions.
ON SAFETY 2
8027740/1FVF/2022-05-19 | SICK O P E R A T I N G I N S T R U C T I O N S | i11s 5
Subject to change without notice

All warranty claims against SICK AG are forfeited in the case of any other use, or
alterations being made to the safety switch, even as part of its mounting or installation.
Correct use includes the regular inspection of the protective device by qualified safety
personnel in accordance with section 5.2.
2.4 General safety notes and protective measures
Safety switches provide a protection function for persons. Incorrect installation or
manipulation can result in serious injuries.
WARNING
Safety switches are not allowed to be bypassed, turned away, removed or made ineffec‐
tive in any other manner. Take measures to reduce bypassing options as necessary.
Observe EN ISO 14119 for using interlocking devices associated with physical guards.
WARNING
The switching procedure may only be activated by actuators specifically designated for
that purpose, which are connected to the protective device in such a manner that they
cannot be detached.
Restrict access to replacement actuators, so they cannot be used for bypassing.

3 Mounting
WARNING
Mounting is only allowed to be performed by qualified safety personnel.
bObserve EN ISO 14119 for using interlocking devices associated with physical
guards.
Fit the safety switches such that
•it is difficult for operators to access when the protective device is open,
•it is possible to inspect and replace the safety switches.
NOTICE
Safety switches and actuators must not be used as a mechanical stop.
NOTICE
Mount only in the assembled condition!
bInsert the actuator into the actuating head.
bMount the safety switch positively. For safety applications (fixed position), mount
safety switch using M5 × 30 screws.
bConnect the actuator to the protective device durably and non-detatchably, e.g.
using one-way bolts or by riveting or welding.
bFit additional stop for moving parts of the protective device.
3.1 Reversing the actuating direction
Figure 1: Reversing the actuating direction
1. Insert the actuator in the safety switch.
2. Loosen the bolts on the control cam.
3. Set the required direction.
4. Tighten screws to 0.8 Nm.
5. Fit enclosed plugs into unused actuator slots.
Figure 2: Minimum approach radius (the pivot point for the door must be in the same plane as
the insertion opening for the actuator)

3.2 Protection against surroundings
A precondition for a durable and perfect safety function is the protection of the control
cam against penetration by foreign matter such as shavings, sand, abrasive materials
etc.; seal unused actuating slots with the enclosed slot covers.
Cover the control slot, the actuator and the rating plate when painting. Use only solvent-
free cleaning materials when cleaning the safety switch.

4 Elektroinstallation
WARNING
The electrical connection is only allowed to be made by qualified safety personnel.
WARNING
Take note of the excess temperature in the casing when selecting insulation material or
pigtails (depending on the operating conditions)!
WARNING
To ensure a secure contact, strip the individual wires back about 6 mm (± 1 mm).
DANGER
For application and usage as per the requirement in cULus, a copper cable (60/70°C)
is to be used.
DANGER
For deployment and use according to the requirements of UL, a class 2 power supply
according to UL1310 must be used.
Figure 3: Opening the safety switch
1. Break open the desired lead-in.
2. Assemble screwed cable gland M16 with the corresponding enclosure rating.
3. Use wire cross section 0.34 to 1.5 mm2.
WARNING Operate all contact pairs in the same voltage range.
4. Connect all live parts to one side of the contact block.

5 Commissioning
5.1 Tests before the initial commissioning
•mechanical functional check It must be possible to insert the actuator into the
actuating head without any problem. Close the protective device several times to
verify.
•electrical functional check
bClose the guard.
bStart the machine.
WARNING
Check whether the machine stops when the guard is opened.
bSwitch off the machine.
bOpen the guard.
bAttempt to start the machine.
WARNING
The machine must not start with a guard open!
5.2 Periodic technical inspections
To ensure correct function over the long term, regular checks are necessary.
Daily or prior to the start of the shift the operator must check for:
•correct function
•no visible evidence of tampering
Regularly according to the machine maintenance schedule by qualified safety person‐
nel:
•correct switching function
DANGER
Check whether the machine stops when the guard is opened.
•safe mounting of the modules
•deposits and wear and tear
•correct sealing of the cable entry or plug connection
•loose cable connections or plug connectors
DANGER
The entire switch and actuator must be replaced in the case of damage or wear and
tear. It is not permitted to exchange individual components or modules!
Safety switches must be completely replaced after 1 million switching operations.
