2 On safety
This chapter deals with your own safety and the safety of the machine operators.
►Please read this chapter carefully before working with the i150RP or with the
machine protected by the i150RP.
The national/international rules and regulations apply to the installation, commission‐
ing, use and periodic technical inspections of the rope-operated switch, in particular
•the Machinery Directive,
•the Low Voltage Directive,
•the Work Equipment Directive,
•the safety regulations as well as
•the work safety regulations/safety rules.
Manufacturers and operators of the machine on which the rope-operated switches are
used are responsible for obtaining and observing all applicable safety regulations and
rules.
2.1 Qualified safety personnel
The i150RP rope-operated 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 of the rope pull switches
Rope pull switches of the i150RP series are electromechanical emergency stop devices
that are actuated using a rope. They are not intended as a substitute for safety guards.
The switched off state is retained until the blue reset lever is actuated, i.e. it is set to
“RUN” position.
For the control this means that
•the dangerous state of the machine must stop as soon as the switch is actuated,
•switch on commands that cause dangerous conditions are only allowed to become
effective when the blue reset lever on the rope-operated switch has been actuated
(„RUN“ position).
Prior to the use of rope-operated switches, a risk assessment must be performed on
the machine.
Important:
The user is responsible for the safe integration of the rope pull 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 simplified procedure in accordance with section 6.3 EN ISO 13849-1 is used for
validation, the Performance Level (PL) may be reduced if several devices are connected
one after the other.
To determine the necessary reliability (Performance Level PL, SIL) for the safety func‐
tion the related standards should be used:

•EN ISO 13849, Safety of machinery — Safetyrelated parts of control systems
•EN 62061, Safety of machinery — Functional safety of safety-related electrical,
electronic and programmable electronic control systems
2.3 Correct use
The i150RP rope pull switch must be used only as defined in section Applications of the
rope pull switches. The rope pull 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.
The product may be used in safety functions.
All warranty claims against SICK AG are forfeited in the case of any other use, or
alterations being made to the rope-operated switch, even as part of its mounting or
installation.
Correct use includes the regular inspection of the rope pull switch by qualified safety
personnel, see "Applications of the rope pull switches", page 5.
2.4 General safety notes and protective measures
Rope pull switches provide a protection function for persons. Incorrect installation or
manipulation can result in serious injuries.

3 Mounting
WARNING
Mounting is only allowed to be performed by qualified safety personnel.
Observe EN ISO 14119 for using interlocking devices associated with physical guards.
►Fit the rope pull switch such that
°the machine is reliably shut down on actuation of the rope in all directions
and the blue reset lever engages in the OFF position,
°the rope extends along the entire operating area and can be accessed easily
and safely,
°the entire length of the rope can be seen on the actuation of the blue reset
lever.
WARNING
On long sections or if the rope changes direction around a corner, it is recommended to
install 1 switch at each end of the rope.
The use of a rope pull switch in combination with a tensioning spring or two rope
pull switches is only permitted up to a certain cable length (see figure 2). Whether a
tensioning spring can be used depends on the risk assessment. The risk assessment
must take into consideration the possibility of an unplanned jamming of the tensioned
rope over its entire length!
►Mount the rope-operated switch using 4 M5 screws.
Figure 1: Mounting the switch
►Tighten screws to 5.0 Nm.
►Install actuation rope.
Max. rope length: 75m

Figure 2: Typical mounting
►If the rope goes round a corner, mount a pulley wheel on either side of the corner.
Figure 3: Changing the direction of the rope
►Using the spring and the rope status indicator, tension rope to required amount.

3.1 Protection against surroundings
A precondition for a durable and perfect safety function is the protection of the switch
against penetration by foreign matter such as shavings, sand, abrasive materials etc.
Mask the type label before applying paint.
