1.2 Application
DGRL
Thermostats are used to control and monitor thermal processes.
Panel-mounting thermostats operate according to the fluid or gas expansion
principle. The electrical switching element is a micro switch.
The devices of the EM type series are available as safety -temperature monitors
STW and safety temperature limiters STB.
In the event of a malfunction, the STB switches the monitored machine line to
an operational safe status.
Versions as per: DIN EN 14597
STW (STB) Safety temperature monitor
STB Safety temperature limiter
Design test as per:
-DIN EN 14597
- Directive governing pressure systems 97/23/EC
- DVGW Gas equipment directive 90/396/EEC (only type EM-80)
1 Introduction
The declaration of conformity can be found in the internet under:
www.jumo.net ➯ Products ➯ Thermostats ➯ Data sheet 602026
or is available on request.
Bending/kinking or cutting the probe line of the panel-mounting thermostats of
A
the EM type series will lead to a permanent device failure!
