Tips
• The service values include not only
current measurement values and
operating states, but also all of the
settings for the controller. Write the
service values down just once after
commissioning has been successfully
completed.
• In the event of uncertainty as to the
control response or malfunctions
the service values are a proven
and successful method for remote
diagnosis. Write the service values
down at the time that the suspected
malfunction occurs. Send the service
value table by fax or e-mail with a brief
description of the error to the specialist
or manufacturer.
• To protect against loss of data, record
any statistics and data of particular
importance at regular intervals.
