22-83 Speed at No-Flow [RPM]
Range: Function:
Closing the valves and reducing the speed
until minimum pressure H
determines this value.

using the pump datasheet.
6.2.8 23-0* Timed Actions
Use Timed Actions for actions needing to be performed on
a daily or weekly basis, e.g. different references for working
hours/non-working hours. Up to 10 timed actions can be
programmed in the frequency converter. The timed action
number is selected from the list when entering parameter
group 23-0* Timed Actions from the LCP.
Parameter 23-00 ON Time – parameter 23-04 Occurrence
then refer to the selected timed action number. Each
timed action is divided into an ON time and an OFF time,
in which 2 different actions may be performed.
Display lines 2 and 3 in the LCP show the status for timed
actions mode (0-23 Display Line 2 Large and 0-24 Display
Line 3 Large, setting [1643] Timed Actions Status).
NOTICE
A change in mode via the digital inputs can only take
place if 23-08 Timed Actions Mode is set for [0] Times
Actions Auto.
If commands are applied simultaneously to the digital
inputs for Constant OFF and Constant ON, the timed
actions mode changes to timed actions auto and the 2
commands are disregarded.
If 0-70 Date and Time is not set or the frequency
converter is set to HAND or OFF mode (e.g. via the LCP),
the timed actions mode is changed to Timed Actions
Disabled.
The timed actions have a higher priority than the same
actions/commands activated by the digital inputs or the
Smart Logic Controller.
The actions programmed in timed actions are merged with
corresponding actions from digital inputs, control word via
bus and Smart Logic Controller, according to merge rules
set up in parameter group 8-5* Digital/Bus.
