SAFEMASTER S
Speed monitor
UH 6932
Product Description
The speed monitor UH 6932 provides safe monitoring of motors and rota-
ting equipment. It is used in machines and plants where machine move-
ments or moving parts can be a danger to men and machine. Using the
front side display the parameters can be easily and comfortably adapted
to the individual application or changed when necessary.

Application
This device is designed for machinery and installations where hazards
to people and property may be caused by the movement of machines or
parts.
With correct connection it is possible to realise with the UH 6932 the sa-
fety functions STO (Safe Torque Off), SOS (Safe Operating Stop), SLS
(Safely Limited Speed), SSM (Safe Speed Monitor) and SSR (Safe Speed
Range) according to EN 61800-5-2. The actual realisation of the safety
functions has to be validated in each application of the product for safety
aspects.
