5. EXAMPLES AND APPLICATION NOTES

5.1. Control application

A TC measures temperature. Each branch of the circuit is
protected by a fuse and the alarm relay is protected with a
snubber circuit. Keep in mind one switch can control multi-
ple indicators.
The diagram below shows the various connections.

With Quick Configuration you set:
•

sensor type (TC);

•

engineering units of temperature (°C);

•

the temperature value that trips the alarm (ALRM1).
