P560 SYNCHR.LIM.
0.0 Hz
Actual Value Output Freq.
Left fct. Up fct. Down fct. Right fct.
This parameter sets the frequency limit: the first assist pump shuts off if the frequency
goes below this parameter's value.
For information about how to find the correct setting, see Example: P500 SUBMENU
SEQUENCE CNTR. (page 104).
P565 SYNCHR.WND.
G
This parameter only applies to cascade synchronous!
P565 SYNCHR.WND.
2.0 Hz
Actual Value Output Freq.
Left fct. Up fct. Down fct. Right fct.
This parameter sets the frequency window: the limit for switching off the next assist pump.
For information about how to find the correct setting, see Example: P500 SUBMENU
SEQUENCE CNTR. (page 104).
8.3.10 M600 ERROR
MENU SCOPE
This submenu includes the following software parameters:
• Minimum threshold limit
• Delay time
• Automatic error reset
P605 MIN.THRESH.
P605 MIN.THRESH.
Disabled
Actual Value Output Freq.
Left fct. Up fct. Down fct. Right fct.
Selects the minimum threshold limit: if an adjusted value > 0.00 is not reached within the
P610 DELAY-TIME, the unit stops (failure message: MIN.THRESH.ERROR).
P610 DELAY-TIME
G
NOTICE:
The minimum threshold function is also active during the start-up of the pump. Therefore,
the delay time must be set higher than the time required to start up the pump and fill the
system.
