10.2.1 Logging maintenance work
The maintenance intervals given are those recommended for average operating conditions.
➤ In adverse conditions, perform maintenance work at shorter intervals.
Adverse conditions are, e.g.:
■ high temperatures
■ too much dust
■ high number of load changes
■ low load
➤ Adjust the maintenance intervals with regard to local installation and operating condi‐
tions.
➤ Documenting all maintenance and service work
This enables the frequency of individual maintenance tasks and deviations from our recom‐
mendations to be determined.
Further information A prepared list is provided in chapter 10.19.
10.2.2 Resetting maintenance interval counters
SIGMA CONTROL BASIC is equipped with a maintenance interval counter. The maintenance in‐
terval counter counts down the operating hours to the next maintenance task.
