The current REQUIRED VALUE and its source (D1 in this example) are displayed.
The available sources are listed below:
D1
internal - required value 1 (set by parameter 0820)
D2
internal - required value 2 (set by parameter 0825)
U1
required value 1 - voltage signal input (Connected to X3/13)
U2
required value 2 - voltage signal input (Connected to X3/15)
I1
required value 1 – current signal input (Connected to X3/18)
I2
required value 2 – current signal input (Connected to X3/23)

Shows the calculated required value based on ACTUAL VALUE INCREASE (0505), ACTUAL VALUE DE-
CREASE (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.
Example: Multi-pump-application with two pumps
REQUIRED VALUE [02]: 75.00 PSI
ACT. VALUE INCREASE [0505]: 10.00 PSI
ACT. VALUE DECREASE [0510]: 5.00 PSI
->
REQ VAL EFF [03]: 80.00 PSI
The second pump will increase system pressure to 80.00 PSI.
