22-83 Speed at No-Flow [RPM]
Range: Function:
300 RPM
*
[0-Value of par. 22-85]
Resolution 1 RPM.
The speed of the motor at which flow Is zero and minimum pressure H
MIN
is achieved should be entered here
in RPM. Alternatively, the speed in Hz can be entered in par 22-84
Speed at No-Flow [Hz]
. If it has been decided
to use RPM in par. 0-02 then par. 22-85
Speed at Design point [RPM]
should also be used. Closing the valves
and reducing the speed until minimum pressure H
MIN
is achieved will determine this value.
22-90 Flow at Rated Speed
Range: Function:
0
*
[0 - 999999.999]
Enter the value corresponding to Flow at Rated Speed. This value can be defined using the pump datasheet.
8.2.11. Timed Actions, 23-0*
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* from the Local Control Panel. Par. 23-00 – 23-04 then refer to the selected Timed Action number. Each Timed Action is divided into an ON time
and an OFF time, in which two different actions may be performed.
NB!
The clock (parameter group 0-7*) must be correctly programmed for Timed Actions to function correctly.
NB!
When mounting an Analog I/O MCB109 option card, a battery back up of the date and time is included.
23-00 ON Time
Array [10]
00:00:00
*
[00:00:00 –23:59:59]
Sets the ON time for the Timed Action.
NB!
The frequency converter has no back up of the clock function and the set date/time will reset
to default (2000-01-01 00:00) after a power down unless a Real Time Clock module with back
up is installed. In par. 0-79,
Clock Fault
, it is possible to program for a Warning in case clock
has not been set properly, e.g. after a power down.
23-01 ON Action
Option: Function:
Select the action during ON Time. See par. 13.52
SL Controller Action
for descriptions of the options.
