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.

bDo not mount safety switches in an environment with interfering magnetic fields.

bNote the possible operating positions.

bMount the actuator on guard so that it cannot be detached (e.g. using safety

screws).

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.
