Instead of setting the flow rate for the system using a flow rate
limiter, it is better to adjust the flow rate using the switch on the
pump and by means of the
“
max. speed
”
setting on the controller
(see 12.9.4). This saves electricity!
The service values (see 15.) include not only current measurement
values and operating states, but also all of the settings for the con-
troller. 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 (see 15.) 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.
