9.11 Operating hours counter
From the time of delivery of the RESISTRON
®
Temperature Controller RES-5009, the operating hours are stored
in the controller. The operating hours counter works with an accuracy of 6 minutes. The operating hours can be
displayed, but not reset. Display is possible with the ROPEX visualisation software (
 section 9.8 "USB interface
for visualisation software ROPEXvisual
®" on page 45
) or via the services of the CAN interface.
9.12 Data storage for error messages and AUTOCAL
To make error diagnosis easier in ongoing operation, the RESISTRON
®
Temperature Controller RES-5009 has a
data storage for error messages (  section 9.15 "Error messages" on page 49) and executed AUTOCAL proce-
dures (  section 9.2.1 "AUTOCAL (AC) automatic zero calibration" on page 30).
The last 400 messages are stored. The messages are read out and displayed with the ROPEX visualisation soft-
ware (
 section 9.8 "USB interface for visualisation software ROPEXvisual
®" on page 45
).
The RESISTRON
®
Temperature Controller RES-5009 also has an integrated clock (  section 9.13 "Integrated
clock (date and time)" on page 47). The messages are then stored with the indication of date and time (time
stamp).
9.13 Integrated clock (date and time)
The RESISTRON
®
Temperature Controller RES-5009 has an integrated clock. The error messages and executed
AUTOCAL procedures are stored in the data storage (  section 9.12 "Data storage for error messages and
AUTOCAL" on page 47) with the indication of date and time (time stamp). This enables a more precise assignment
of error messages when analyzing problems, for example.
The integrated clock can be set and read out through the ROPEX visualisation software (
 section 9.8 "USB inter-
face for visualisation software ROPEXvisual
®" on page 45
) or through services of the CAN interface.
A maintenance-free capacitor is used for operation of the clock. There is no battery installed, so there is no need
to change the battery.
• The controller must be switched on for at least 3 hours to fully charge the capacitor for the clock.
• If the controller is switched off, a fully charged capacitor can operate the clock for approx. 2…4 weeks.
• If the controller is switched off longer, the date and time must be set again.
The capacitor is discharged when shipped from the factory. During initial startup of the controller, the clock must
be set when the error messages in the data storage (
 section 9.12 "Data storage for error messages and
AUTOCAL" on page 47) are to be stored with date and time.
Operation of the controller is possible without the clock being set. In this case, invalid values for date and time will
be stored in the data storage (

section 9.12 "Data storage for error messages and AUTOCAL" on page 47). The
behaviour of the temperature control is not influenced by this.

NOTE
The stored messages can be exported as a csv-file. If needed, ROPEX can evaluate the
exported file and create an error diagnosis.
