16.5 Test alarm of the safety temperature limiter (TL)

The safety temperature limiter (TL) provides temperature monitoring with a fixed switching threshold. It is
an essential element of the manufacturer's safety plan to prevent ignition and explosions (chap. 3.1).
Therefore, an annual function check by the operator is recommended. To do this, you can use the con-
troller test routine described following.
For chambers equipped with a single safety temperature limiter (TL), this is tested with the setting "1". For
chambers with 2 TB, the test is run twice, first with the setting "1" and then again with the setting "2".
