7.3.5 Unit of measure LEDs description
Speed
When Speed (pump impeller speed) is the measurement selected:
The current rotation speed measure [expressed as revolutions per minute divided by 10] is
displayed on
The 10xRPM LED is lit.
Head
When Head (hydraulic water head) is the measurement selected:
The current water head measured expressed in BAR (or PSI) of water head, (dependent from
P41 value, see par. 7.5.4 ) is displayed on the numeri
The BAR (or PSI) LED is lit.
7.4 Numeric display
7.4.1 Main visualization
Off mode
OFF is visualized when the contacts [11,12] (see par. 5.5) are not short circuited.
Off mode, has lower visualization priority than Stop mode.
Stop mode
STP is visualized when the pump is manually stopped.
If the pump is powered-on having previously set P04 = Off (see par. 7.5.1), pump is stopped so
pump motor is not running and STP blinks (STP STP).
To manually stop the pump, follow next examples:
Example 1 (valid for HCS, MES, MSY control modes with an initial required value (Head) of
4.20 [BAR] and a minimum value of 0.5 [BAR]):
BAR 4.20 single press STP.
Example 2 (valid for ACT control mode with an initial required (Speed) value of 200 [10xRPM]
and a minimum value of 80 [10xRPM]):
10xRPM 200 single press STP.
Running mode
ON is visualized for few seconds, when the contacts [11,12] are short circuited and the pump is
not in Stop Mode.
This visualization indicates that the pump is switched on and the motor shall start (dependently
from selected control mode).
To manually set the pump to Running Mode, follow next examples:
Example 1 (valid for HCS, MES, MSY control modes reaching a required value (Head) of 4.20
[BAR] by starting with a minimum value of 0.5 [BAR], after a manual stop):
STP single press ON after few seconds… 4.20 BAR.
Example 2 (valid for ACT control mode reaching a required value (Speed) of 200 [10xRPM] by
starting with a minimum value of 80 [10xRPM] , after a manual stop):
STP single press ON after few seconds 200 10xRPM.
While pump is running, both Actual Head and Actual Speed can be shown by Numeric display [6]
as in the following examples:
Example 3 (valid for HCS, MES, MSY control modes with an Actual Head of 4.20 [BAR] and a
corresponding Actual Speed of 352 [10xRPM]):
BAR 4.20 + 352 10XRPM after 10 seconds or + 4.20 BAR.
Example 4 (valid for ACT control mode with an Actual Speed of 200 [10xRPM] and a
corresponding Actual Head of 2.37 BAR):
10xRPM 200 + 2.37 BAR after 10 seconds or + 200
10xRPM.
