Setting In Connection With Pump Replacement; Max. Or Min. Curve Duty; Constant Curve Duty - Grundfos UPE 2000 Series Montage- Und Betriebsanleitung

6.3.1 Setting in connection with pump
replacement
If an uncontrolled pump is to be replaced with a UPE
Series 2000, settings can be made according to the
tables below.

Read the tables as follows:
• If the maximum head of the existing pump is 6 me-
tres and the pump is running at maximum speed
under normal operating conditions, it is recom-
mended to set the UPED pump to 3 metres and to
select proportional pressure.
• If, however, the existing pump is running at a re-
duced speed, it is recommended to set the UPED
pump to 2 metres and to select constant pressure.

6.4 Max. or min. curve duty

Can be set by means of the control panel or the
R100.
The pump can be set to operate according to the
max. or min. curve, like an uncontrolled pump, see
fig. 9.

The max. curve mode can be selected if an uncon-
trolled pump is required. In this operating mode, the
pump will operate independently of an external con-
troller, if installed.
The min. curve mode can be used in periods in
which a minimum flow is required. This operating
mode is suitable for night-time duty.
Two different min. curves can be set by means of the
R100.

6.5 Constant curve duty

Can be set by means of the R100.
The pump can be set to operate according to a con-
stant curve, like an uncontrolled pump. Select one of
19 curves between the max. and min. curves, see
fig. 10.
