6.3.11 23-0* Timed Actions
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 LCP. Par. 23-00 ON Time – par. 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 two different actions may be performed.
The actions programmed in Timed Actions are merged with corresponding actions from digital inputs, control work via bus and Smart Logic ControllerLogic
Controller, according to merge rules set up in 8-5*O-5#, Digital/Bus.
NB!
The clock (parameter group 0-7*) must be correctly programmed for Timed Actions to function correctly.
NB!
When mounting an Analog I/O MCB 109 option card, a battery back up of the date and time is included.
NB!
The PC-based Configuration Tool MCT 10DCT 10 comprise a special guide for easy programming of Timed Actions.
Function:
Enter the value corresponding to the Pressure at Rated Speed, in Reference/Feedback Units. This
value can be defined using the pump datasheet.
Function:
Resolution 1 RPM.
The speed of the motor at which flow Is zero and minimum pressure H
entered here in RPM. Alternatively, the speed in Hz can be entered in par. 22-84
[Hz] . If it has been decided to use RPM in par. 0-02 Motor Speed Unit then par. 22-85 Speed at
Design Point [RPM] should also be used. Closing the valves and reducing the speed until minimum
pressure H is achieved will determine this value.
MIN
Function:
Enter the value corresponding to Flow at Rated Speed. This value can be defined using the pump
datasheet.
