3 Product description

3.1 Setup and function

The safety switch consists of two components:

Sensor

•

The sensor is mounted on the fixed part of the protective device.

Actuator (transponder)

•

The actuator is mount

When the protective device is closed, the actuator is guided to the sensor. When the switch on distance is reached, the sensor detects the actuator code. If the sensor detects a taught-in code (valid actuator), it sets safety outputs OSSD 1 and OSSD 2 (semiconductor outputs) to High and application diagnostic output Aux to Low.

When the protective device is opened, the actuator is removed from the response range of the sensor. The sensor sets safety outputs OSSD 1 and OSSD 2 to Low and applica‐ tion diagnostic output Aux to High.

Perform a risk assessment before using the safety switch.

Do not manipulate, open, or modify components of the safety switch.

Do not repair defective devices; replace them instead.

Make sure the switch-on commands that cause the machine to enter a dangerous

state only take effect when the protective device is closed. Make sure a stop command is triggered when the protective device is opened in a

hazardous machine state. Safety switches must not be bypassed (i.e., the contacts jumpered), swiveled out

of the way, removed, or rendered ineffective in any other way. If necessary, take measures to reduce the possibility of bypassing.

Incorrect mounting and unsuitable ambient conditions may damage the safety switch.

Arrange the sensor and actuator in a way that prevents damage from foreseeable

external influences. Do not use the sensor and actuator as a stop.

The holder and mounting method for the sensor and actuator must be stable

enough to ensure that correct operation can take place. Always use reliable mounting elements that can only be removed using tools.

If t fully:

When the protective device is closed, the sensor and actuator must face each

other at the safe switch on distance of Sao or closer (see table 3). Select a mounting location that allows the sensor and actuator to be accessed for

maintenance work and protects them against damage. If possible, mount the sensor and actuator on non-ferrous subsurfaces and at a

distance from metallic parts in order to avoid affecting the sensing range. If this is not possible, the effect on the safe switch on distance Sao and the safe switch off

distance Sar must be checked. Make sure that there is no possibility of hazards arising when the protective device

is opened, even if the actuator has not yet reached the safe switch off distance Sar.

If the actuator is approaching the sensor in a parallel position, observe the mini‐

mum distances (see table 3). If necessary, attach an additional stop for the moving protective device.

PELV (IEC 60204-1) for all devices that are electrically connected to the safety switch. All devices that are electrically connected to the safety switch must have the same

voltage supply. Use protected cable routing to eliminate cross-circuits and short-circuits.

Power devices (such as motors) that represent a strong source of interference

must be kept isolated from circuits for signal processing. Route the cables for the safety circuits as far away as possible from the power circuit cables. Make sure that 1 A fuse protection is provided for safety switches.

Make sure that all electrical outputs have an adequate suppressor to accommo‐

date inductive loads. For this purpose, the outputs must be protected with an appropriate suppressor such as a freewheeling diode, a varistor, or an RC element.

DANGER

Hazard due to lack of effectiveness of the protective device

The dangerous state may not be stopped in the event of non-compliance.

Operate safety switches within the specifications. If you operate them outside the

specifications, this may result in the sensor temperature increasing and in a loss of the safety function. Make sure that a current of no more than 100 mA is flowing at safety outputs

In the case of non-compliance, it is possible that the dangerous state of the machine may not be stopped or not stopped in a timely manner.

1. Have qualified safety personnel perform a thorough check on the machine and

approve it before commissioning.

2. Make sure that the time for the safety requirement (closing the protective device

again) is longer than the risk time.

7.2 Switching on

The device initializes after switching on. During this process, the OSSDs are switched off and the light emitting diodes light up alternately in the color sequence green, red, and yellow. For unique coded and permanently coded safety switches only: If any actua‐ tors have already been taught in, the STATE light emitting diode will flash once after ini‐ tialization for each taught-in actuator.

The reaction times are subject to the following parameters:

esponse time or enable time

•

Number of cascaded devices

•

Response time (r

Response time for cascade: 40 ms + 80 ms * number of safety switc

Enable time (actuator approaching response range)

Enable time for cascade: 100 ms + 80 ms * number of safety switches in cascade

emoval of actuator from response range)
