Product Overview

Structure and Function Product Features

The safety switch is an interlocking device with a locking device, which consists of a non-contact sensor with locking solenoid, and a coded actuator. The actuator has a low coding level.
If the protective device closes, the actuator leads to the sensor. When the actuation field is reached, the actuator code reads out and is evaluated by RFID. If the code is valid, the safe output signal switching device (OSSD) switches.
If the locking solenoid has power supply, the locking device is active.

Product Models
The safety switch is available in different models. The following is an overview of the unique features of the models:
· One cable with M12 plug connector (5-pin) · One cable with M12 plug connector (8-pin)
Locking Principle
ATTENTION: Hazard due to lack of effectiveness of the protective device. If a voltage drop occurs, the locking device unlocks regardless of whether the dangerous state of the machine is ended. · Do not use the safety switch in applications where the dangerous state cannot
be ended immediately (stopping/run-down time).
Power to Lock Principle
· Lock locking device: voltage at locking device input · Unlock locking function: no voltage at locking device input
If voltage is interrupted, the locking device unlocks and the protective device can open immediately.
The locking device is not monitored, which means that the safety switch does not check whether the anchor plate is applied to the solenoid.
Protective Functions
The safety switch has the following internal protective functions: · Short- circuit protection at all outputs · Cross-circuit monitoring at OSSDs · Overload protection on OSSDs · Supply voltage reverse polarity protection

ATTENTION: Failure to comply with obligations of manufacturer. Hazard due to lack of effectiveness of the protective device. · Conduct a risk assessment before using the safety switch. · Do not tamper with, open, or modify the components of the safety switch. · Do not repair defective devices ­ they must be replaced instead. · Confirm that switch-on commands, which bring about a dangerous state of
the machine, are not enabled until the protective device is closed. · Make sure that a stop command is triggered when the protective device is
opened during the dangerous machine state. The safety switches must not be defeated (such as jumpered contacts), rotated away, removed, or rendered ineffective in any other way. If necessary, put measures in place to reduce possibilities for defeat.
ATTENTION: Failure to comply with obligations of the operating entity. Hazard due to lack of effectiveness of the protective device. · Modifications to the machine and modifications to the mechanical mounting
of the safety switch necessitate a new risk assessment. The results of this risk assessment can require the operating entity of the machine to fulfill the obligations of the manufacturer. · Apart from during the procedures described in this document, the components of the safety switch must not be opened or modified. · Do not perform repair work on the components. Improper repair of the safety switch can lead to a loss of the protective function. · Verify that there is no bypassing by replacement actuators. Restrict access to actuators.
ATTENTION: Bypassing the protective device. Hazard due to lack of effectiveness of the protective device. Avoid incentives to manipulate the safety switch by taking at least one of the following measures: · Cover the sensor and the actuator with additional equipment or protect them
against access. · If possible, use permanent mounting methods for actuators (for example, glue,
safety screws, or rivets).

Mounting Location
· Select the mounting location so that the sensor and actuator are accessible for maintenance work and are protected against damage.
· Select a mounting location for the sensor that is as far away from the door hinge as possible.
· If necessary, fit an additional stop for the moving protective device.
Distance
When several safety switches are mounted to the machine, they must be mounted at a minimum distance to one another, see Mount Multiple Safety Switches on page 19.
Alignment
The safety switch can be mounted in any alignment. When mounted horizontally, the anchor plate with rotating bearings increases the manipulation protection. When mounted horizontally, if the movable physical guard triggers the actuator, the magnet holds the actuator. As the anchor plate has rotating bearings, the gravitational force rotates the actuator surface away from the sensor surface and the OSSDs go into the off state.
Mounting Methods
The sensor can be mounted in the following ways: · Surface mount: The sensor is mounted on the fixed part of the protective device (for example, the door frame). · Flush mount (1): The sensor is mounted in the fixed part of the protective device (for example, the door frame). There must be a suitable recess in the mounting surface. The thickness of the mounting surface must be 1.5…3 mm (0.06…0.12 in.).
Switch-on commands that put the machine in a dangerous state can only be activated when the protective device is closed. When the machine goes into a dangerous state, a stop command must be triggered if the protective device is opened. Depending on the safety concept, a safety relay or a safety controller analyzes the signal.
The control that is connected and all devices responsible for safety must comply with the required Performance Level and the required category (for example, according to ISO 13849-1).
OSSDs
Safety switches with local inputs and outputs can be directly integrated into the machine controller.
ATTENTION: Hazard due to lack of effectiveness of the protective device. If non-compliant, it is possible that the dangerous state of the machine cannot be stopped or not stopped in a timely manner. · Verify that the following control and electrical requirements are met so the
protective function can be fulfilled.
(1) For the recess dimensions for flush mounting, see Figure 12 on page 34
Rockwell Automation Publication 440G-UM003C-EN-P – March 2022

Chapter 3 Project Planning
· The output signals from an OSSD pair must not be connected to each other.
· In the machine controller, both signals from an OSSD pair must be processed separately.
Figure 4 – Dual-channel and isolated connection of OSSD 1 and OSSD 2

· The machine must switch to the safe state at any time if at least one OSSD in an OSSD pair switches to the off state.
· Help prevent the formation of a potential difference between the load and the protective device. If you connect loads to the OSSDs (safety outputs) that then also switch if controlled with negative voltage (for example, electromechanical contactor without reverse polarity protection diode), you must connect the 0V connections of these loads and the connections of the corresponding protective device individually and directly to the same 0V terminal strip. If there is a fault, this way verifies that there can be no potential difference between the 0V connections of the loads and the connections of the corresponding protective device.
Figure 5 – No Potential Difference Between Load and Protective Device

ATTENTION: Hazard due to lack of effectiveness of the protective device. If non-compliant, it is possible that the dangerous state of the machine cannot be stopped or not stopped in a timely manner. Downstream contactors must be positively guided and monitored depending on applicable national regulations or required reliability of the safety function. · Make sure that downstream contactors are monitored (external device
monitoring, EDM).

Requirements for the Electrical Control of the Machine
· Use the control without test pulses. The safety switch is self-testing.
· The safety switch tests the OSSDs at regular intervals. To conduct this test, it switches each OSSD briefly (for max 1 ms) to the off state and checks whether this channel is voltage-free during this time.
· Make sure that the control of the machine does not react to these test pulses and the machine does not switch off.
· The inputs of a connected evaluation unit must be positive-switching (PNP), as the two outputs of the safety switch send a level of the supply voltage in the switched on state.

Chapter 3 Project Planning 16

The OSSDs are short-circuit protected to 24V DC and 0V. When the actuator is in the response range of the sensor, the OSSDs signal the on state with the high signal level (non-isolated). If the actuator is removed from the response range of the sensor or there is a device fault, the OSSDs signal the off state with the low signal level.
The safety switch complies with the regulations for electromagnetic compatibility (EMC) for the industrial sector (Radio Safety Class A). Radio interference cannot be ruled out when used in residential areas.
ATTENTION: Hazard due to lack of effectiveness of the protective device. If non-compliant, it is possible that the dangerous state of the machine cannot be stopped or not stopped in a timely manner. · Verify that the following control and electrical requirements are met so the
safety switch can fulfill its protective function.

· The external voltage supply of the safety switch must be able to withstand brief power failures of 20 ms as specified in IEC 60204-1.
· The power supply unit must provide safe isolation according to IEC 61140 (SELV/PELV). Suitable power supplies are available as accessories, contact your local Allen-Bradley product distributor or Rockwell Automation sales office.

Locking Solenoid Control
The locking solenoid is activated through the upstream control. There is no internal activation or deactivation of the locking solenoid through the safety switch. The locking device and locking force are not monitored. When the machine starts, the following sequence must be followed:
1. Check whether safety switch OSSDs are in the on state. 2. Supply the locking solenoid with power. 3. Start the machine.
Application Diagnostic Output
The application diagnostic output signal changes as soon as the actuator is moved into or out of the response range of the safety switch. That is, when the movable protective device is opened or closed. This output is not a safety output.

Thorough-check Concept

Appropriately qualified safety personnel must test the safety switch during commissioning, after modifications, and at regular intervals; see Thorough- check Requirements on page 27.
Regular thorough checks serve to investigate the effectiveness of the safety switch and discover anomalies that result from modifications or external influences (such as damage or manipulation).
The manufacturer and operating entity must define the type and frequency of the thorough checks on the machine based on the application conditions and the risk assessment. The process of defining the thorough checks must be documented in a traceable manner.

Thorough-check Requirements

Commissioning

6 Chapter

ATTENTION: Hazard due to lack of effectiveness of the protective device. If non-compliant, it is possible that the dangerous state of the machine cannot be stopped or not stopped in a timely manner. · Before commissioning the machine, have qualified safety personnel check
and release it. · Verify that the time for the safety requirement (closing the protective device
again) is longer than the response time.

The device initializes after it is switched on. OSSDs are switched off in the meantime. The OSSD light-emitting diode lights up after initialization.

The protective device and its application must be thoroughly checked in the following situations:
· Before commissioning.
· After changes to the configuration or the safety function.
· After changes to the mounting, the alignment, or the electrical connection.
· After exceptional events, such as after a manipulation has been detected, after modification of the machine, or after replacing components.

The thorough check verifies the following:
· All relevant regulations are complied with and the protective device is active for all operating modes of the machine.
· The documentation corresponds to the state of the machine, including the protective device.

Qualified safety personnel or specially qualified and authorized personnel must conduct the thorough checks and must be document results in a traceable manner.

IMPORTANT

· Check whether the protective device of the machine is effective in all operating modes in which the machine can be set.
· Verify that operating personnel have been instructed in the function of the protective device before starting work on the machine. The machine operator has overall responsibility for the instruction, which qualified personnel must conduct.

Maintenance and Troubleshooting

Maintenance Troubleshooting

Clean the Switch

IMPORTANT

· Do not use aggressive cleaning agents (such as isopropanol or spirit). · Do not use any substances that hinder the wetting properties of
lacquers. · We recommend anti-static cleaning agents.

Regular Thorough Check
The safety switch must be checked regularly. The manufacturer and the operating entity of the machine defines the type and frequency of thorough checks, see Thorough-check Concept on page 18.
The regular thorough checks serve to investigate the effectiveness of the safety switch and detect any ineffectiveness due to modifications or external influences (for example, damage or manipulation).
IMPORTANT Conduct the thorough checks according to the instructions from the manufacturer and the machine user.

ATTENTION: Hazard due to lack of effectiveness of the protective device. If non-compliant, it is possible that the dangerous state of the machine cannot be stopped or not stopped in a timely manner. · Immediately shut down the machine if the behavior of the machine cannot be
clearly identified. · Immediately shut down the machine if a machine fault cannot be determined
or safely rectified. · Secure the machine so that it cannot switch on unintentionally.

ATTENTION: Hazard due to unexpected starting of the machine. When any work is taking place, use the protective device to secure the machine or to verify that the machine is not switched on unintentionally.

ATTENTION: Hazard due to lack of effectiveness of the protective device. If non-compliant, it is possible that the dangerous state of the machine cannot be stopped or not stopped in a timely manner. · Do not repair device components. · Do not modify or manipulate device components. · Apart from during the procedures described in this document, the device
components must not be opened.

Chapter 7 Maintenance and Troubleshooting
IMPORTANT If you cannot remedy the fault with the help of the information that is provided in this chapter, contact your local Allen-Bradley product distributor or Rockwell Automation sales office.
Perform one of the following steps when an error occurs: · Check voltage supply. · Check cables. · Check alignment of safety switch and actuator. · Check ambient conditions (for example, interfering RFID frequencies or magnetic fields, distances to other safety switches).
IMPORTANT If a safety switch has a fault in a cascade with an end connector, the OSSDs of all safety switches between the safe evaluation unit and the safety switch concerned switch into the off state.
