Safety Technique
SAFEMASTER W Wireless Safety System
Radio Controlled Safety Module
UH 6900

Product Description

The radio controlled safety module UH 6900 is an innovative wireless sa-
fety system to protect man and machine. A feature of the wireless safety
system is its safety-oriented bi-directional radio transmission for transmit-
ting signals between two wireless safety modules so that the two separate
safety devices, each of them installed on a different machine part that is
not connected to the other by wires (for example, moving machine parts),
work together as one system.
Therefore SAFEMASTER W radio controlled safety modules are intended
for the wireless remote control of machines and plant parts that used to be
controlled by cable. Their usage is only restricted by valid safety instruc-
tions that prohibit, for example, staying under suspended loads.
Typical applications are:
• Hazard areas where protective equipment is necessary for the safety of
persons but where wiring is impossible or not reasonable, for example
in applications with extremely wide-spread, extensive hazard zones;
• Mobile and stationary plants and equipment, for example large machi-
nes, assembly halls and scaffolds, conveyor belts, high-rack warehouses,
warehouses, forklifts, etc.
• The radio transmission range is up to 800 m

Notes

Before installing, operating or maintaining this device, the user manual

- Safety shut-down commands
- Signals from 8 non-safety-relevant DC 24 V inputs at 8 non-safety-
relevant DC 24 V semiconductor outputs
• Broken wire and short circuit monitoring function with error indication
• Semiconductor output to indicate poor or missing radio control
• 2 semiconductor outputs for status indication
• LEDs to indicate
- status of module
- status of all inputs and outputs
- the radio transmission and its quality
• Width: 45 mm

Approvals and Markings

Functions

Each UH 6900 radio controlled safety module is installed in a switch ca-
binet or on a mobile device and is operated with a plug-in or external
antenna. It detects the signals of up to three wired safety elements plus
the signals from the related second active radio controlled safety module
that are sent through a safe radio transmission. Safety-relevant switching
commands are switched by relay outputs, non-safety-relevant control si-
gnals through semiconductor outputs.
In addition, a non-contact sender and a non-contact receiver (for example,
light curtain or infrared sender and receiver) may be connected to force
the system to start from a specific location via radio.
