message. Examine the error message on the controller. Refer to
the sensor documentation for solutions. Make sure that
the error is shown in the service menu and push
START.
Instrument
warning The instrument caused a warning

Warm-up phase The inside of the instrument is too
cold (e.g., the enclosure door was
open at low external
temperatures). Wait until the warm-up phase is completed. If the start-
up temperature was higher, the warm-up phase can
vary from a few minutes to an hour.
Cooling down The instrument is overheated and
is cooling-down. If the instrument
version has a filter probe, the
compressor is deactivated in this
phase.
• Wait until the cooling-down phase is completed.
• Make sure that no blockage of the vent is caused.
• Clean or change the air filter.
• Complete a function test on the fan.
• Specify the correct operating temperature.
