Xylem HYDROVAR HV 4.150 / 4.185 / 4.220 - Manual (Page 53)

03
03 EFF REQ VAL
D1 X.XX Bar
Effective required value
Shows the current required value that is calculated based on ACTUAL VALUE INCREASE
[0505], ACTUAL VALUE DECREASE [0510] and LIFT AMOUNT [0330]. If the required value is
influenced by an offset signal (SUBMENU OFFSET [0900]) the current active required value
is also shown in this window.
E.g. Multi-pump-application with two pumps
REQUIRED VALUE [02]: 5.00 bar
ACT. VALUE INCREASE [0505]: 0.50 bar
ACT. VALUE DECREASE [0510]: 0.25 bar
-> REQ VAL EFF [03]: 5.25 bar
After starting the second pump the pressure will be increased to a system pressure of 5.25
bar. With this parameter you are able to see the calculated new required value.
c) Active MODE [0105] = Actuator
Frequency XX.X Hz
STOP X.XX Bar
1 st display in Mode actuator
If parameter MODE [0105] is set to actuator the parameter REQUIRED VALUE [02] will
change to ACTUAT. FREQ. and is equivalent to parameter [0830].
By using this parameter it is possible to run the HYDROVAR up to two pre-selected
frequencies to manually control the HYDROVAR.
02
02 ACTUAT.FRQ.
D1 XX.X Hz
Set the desired frequency with either ▲ or ▼
The selected frequency in this parameter is only active in the actuator mode. The
configuration must be done with parameter C.REQ.VAL.1 [0805] or C.REQ.VAL 2 [0810]
and parameter SW REQ.VAL [0815].
For manual setting of the frequency the parameters ACTUATOR FREQUENCY 1 [0830] and
ACTUATOR FREQUENCY 2 [0835] can be used.
For detailed information how to run the HYDROVAR by manual control, see submenu
REQUIRED VALUES [0800].
