FAQ
Wireless safety system RE 6900 SAFEMASTER W
What is the wireless safety system RE 6900?
The wireless safety system RE 6900 from the SAFEMASTER W series is the perfect solution if you want to work safely and reliably in hazardous areas during machine maintenance or setup – all while enjoying maximum mobility and the highest level of safety.
What components are included in the wireless safety system RE 6900?
In pair mode, the wireless safety system RE 6900 consists of a transmitter – available as either a wireless enable switch or a wireless emergency stop – and a corresponding wireless safety module UH 6900 as the receiver.
In group mode, the wireless safety system RE 6900 consists of a transmitter – either a wireless enabling switch or a wireless emergency stop – and up to 255 group receivers UH 6900. The wireless handheld transmitter RE 6900 is paired with one or more group receivers UH 6900.
What is the difference between a wireless enabling switch and a wireless emergency stop?
The wireless enabling switch enables safe movements during service, setup, or maintenance operations, while the wireless emergency stop allows for remote, mobile safety shutdown of machines. With the wireless enabling switch, a hazardous area can be safely entered at reduced speed, as the hazardous movement is only continued when active consent is given.
How does a wireless enabling switch work?
The wireless enabling switch enables safe operation and prevents the unintentional initiation of hazardous movements, as only an active middle position of the three-position switch grants permission for the machine movement via radio. Releasing or pressing the switch all the way interrupts the movement and triggers a safety-related shutdown.
How does a wireless emergency stop work?
Pressing the emergency stop button sends a safety-related emergency stop signal via radio to the associated wireless safety module UH 6900, which puts the system into a safe state.
What safety level does the wireless enabling switch RE 6900 achieve?
The wireless enabling switch fulfils the requirements up to Category 4 / Performance Level e (PL e) in accordance with EN ISO 13849 and SIL 3 in accordance with IEC 61508, making it suitable for safety-critical applications.
For which applications is the wireless enabling switch suitable?
The wireless enabling switch is primarily used in the servicing, maintenance, and setup of machines and systems to protect personnel. Examples of applications include:
- Robotic cells
- Factory automation
- Intralogistics
- Mobile AGVs
- Industrial vehicles and forklifts
- Maintenance of trains, tractors, or combine harvesters
- Gondolas (cable cars, metal industry, etc.)
For which applications is the wireless emergency stop suitable?
Machines and systems must be equipped with an emergency stop button in accordance with standards. In mobile applications, these cannot be wired – this is where our wireless emergency stop is ideally suited for use. Examples of applications include:
- Motor-driven machines in wood and metal processing, etc.
- Overhead cranes
- Mobile harvesters
- AGVs
- Mobile automatic forklifts
- Presses, saws, and cutting machines
- Gas stations
- Applications requiring rapid response times or short work cycles
Use is not permitted where there is direct contact with the hazard, such as in robotic cells.
What are the advantages of a wireless safety system?
Wireless safety systems provide operators with greater freedom of movement, flexible protection for large facilities, and faster response times in hazardous situations. A wireless safety system is essential for ensuring compliance with safety standards. Wireless solutions offer economic advantages, particularly for large facilities, as they eliminate the need for costly cabling. At the same time, there is no wear on cables, and damage caused by environmental factors is prevented.
What radio frequencies does the wireless enabling switch RE 6900 use?
The wireless enabling switch operates in the license-free frequency range of 433 – 434 MHz or 869 MHz, allowing it to be used flexibly in industrial applications.
How is the wireless enabling switch RE 6900 configured?
The wireless enabling switch is configured using the SAFEMASTER W Manager software, which allows for easy setup, parameterization, and diagnostics.
How is the wireless enabling switch RE 6900 commissioned?
Commissioning is performed using the free SAFEMASTER W Manager configuration software and consists of three steps:
- Connect the devices via USB
- Configure parameters using the software
- Perform a function test.
What diagnostic features does the system offer?
The software provides status displays, logging, reception quality indicators, and spectrum analysis of the radio channels.
How is it ensured that only authorized persons use the system?
The system can be personalized using an RFID-based electronic key, ensuring that only authorized operators have access.
What additional functions does the wireless enabling switch offer?
Additional functions include infrared start, shock detection, motion and position detection, and gesture control.
How is the wireless enabling switch started?
The system is activated via a start button on the handheld transmitter, which establishes the wireless connection to the safety module.
Can the system also be used in large facilities?
Yes, especially in large or hard-to-monitor facilities, the wireless emergency stop enables a quick mobile shutdown.
What role does the charging cradle play in the system?
The charging cradle is used to charge the handheld transmitter and for secure storage. RFID ensures a unique pairing between the wireless handheld transmitter and the charging cradle.
What advantages does the spectrum analysis feature offer in the system?
The integrated Spectrum Analyzer displays available radio channels and assists in selecting the optimal, interference-free radio channel.
Which industries benefit most from the RE 6900 wireless safety system?
Typical applications include automation technology, robotics, conveyor systems, logistics and production facilities, and mechanical engineering.
What is the purpose of the infrared start?
In addition to starting the system in normal operation, it can also be started via infrared (IR start). To do this, the handheld transmitter is aimed at the infrared module (IR receiver) located on the system to be monitored. If this option is enabled, the receiver expects both a start signal via radio and a start signal via infrared before granting permission. This limits the system’s start-up to a defined spatial zone with a visible danger area.
