2 On safety
This chapter deals with your own safety and the safety of the equipment operators.
bPlease read this chapter carefully before working with the safety switch or with the
machine protected by the safety switch.
The national/international rules and regulations apply to the installation, commission‐
ing, use and periodic technical inspections of the safety switch, in particular the work
safety regulations and safety rules.
2.1 Qualified safety personnel
The 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
•who have been instructed by the responsible machine operator in the operation of
the machine and the current valid safety guidelines
and
•who have access to the operating instructions.
2.2 Application
Series RE300 safety switches are magnetically operated, non-contact safety switches.
In combination with a suitable safety-related evaluation unit, they protect movable
guards in the following way:
•The dangerous state of the machine can only be switched on when the guard is
closed.
•If the guard is opened while the machine is running, a stop command is triggered.
For the control this means:
•Activation commands that result in dangerous states are only allowed to become
effective if the guard is in the protective position.
•Dangerous states must have been terminated before the protective position is left.
Prior to the use of safety switches, a risk assessment must be performed on the
machine.
2.3 Correct use
The safety switch must be used only as defined in section "Application", page 5. 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 instruc‐
tions.
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 safety switch, even as part of its mounting or installation.
Correct use includes also regular inspection of the guard by qualified safety personnel
in accordance with section 6.2.

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.
DANGER
Safety switches are not allowed to be bypassed, turned away or made ineffective in any
other manner.

3 Function description
The safety switch is magnetically coded. Its contacts are operated by the related actua‐
tor RE300-KA. The safety switches are equipped with contacts:
The switching signals are sampled by a suitable safety-related evaluation unit, e.g. a
safe programmable logic controller.
3.1 Evaluating the switching signals
On integrating magnetic safety switches into suitable safe evaluation units, the follow‐
ing must be taken into account:
•The user is responsible for ensuring that the device is safely incorporated into
a safe overall system. This involves validating the overall system according to
specifications such as those defined in EN ISO 13849-2.
•On the detection of a fault related to the safety switch, the safe evaluation unit
must shut down and adopt a locked state.
•Both contacts must switch opposite to each other with a maximum discrepancy
time of 1500 ms; this time is to be monitored using the evaluation electronics.
•On the connection of the safety switch to a safe evaluation unit, the input module
should be configured such that the discrepancy time set has no effect on the
shutdown time for the evaluation (typical configuration “provide 0”). If this is not
possible, the calculation must take into account the response time.

4 Mounting
WARNING
Mounting is only allowed to be performed by qualified safety personnel.
bPay attention to EN ISO 14119 on mounting the safety switch and the actuator.
bPay attention to EN ISO 14119 on reducing possible ways of bypassing an inter‐
locking device.

14119
bDo not mount safety switches in an environment with interfering magnetic fields.
bNote the possible operating positions.

bTighten self-locking screws to 1.0 Nm.
bDo not use anaerobic adhesive (e.g. Loctite) to lock the screws, as this will attack
the plastic housing.
