Operating time indicates the time the controller
has been operating since the last start-up of the
controller in days.hours:Minutes:Seconds.
The total operating time refers to how long the
controller has been supplied with voltage (Days.
Hours:Minutes:Seconds).
NOTICE
!
Controller damage due to the violation of the
permissible ambient temperature range.
Î When installing the controller, observe the
permissible ambient temperature (0 to
50 °C).
The device inside temperature is monitored to
protect the controller and to guarantee the
measuring accuracy of the analog inputs. The
measuring error at the analog inputs increases,
the more the ambient temperature deviates from
20 °C (see the 'Design and principle of
operation' section). If the temperature inside the
controller falls below 0 °C or rises above 60 °C,
a message is generated in Last events. If the
temperature inside the controller falls below
–5 °C or rises above +65 °C, a further message
is generated in Last events and Error message
