6.1.1 Display Rules
The displays appearing in the PMU 2000 menu are dependent on
the settings and the data transmitted from the units connected to
the GRUNDFOS BUS.
The displays which are not relevant according to the settings and
the units connected to the GRUNDFOS BUS will be suppressed.
All possible displays and values defined in the software will ap-
pear if they have not been suppressed as described above.
6.1.2 Status Display
The status display is the first display that appears when the PMU
2000 is switched on.

Status
If the PMU 2000 is not operated for 15 minutes, it will automati-
cally return to this display.
By pressing "Esc" repeatedly, you can always return to this dis-
play.
The status display indicates the following:
[I]
Pumps 1, 2, 4 and 6 are operating.
[A] Fault indication on pump 3.
The fault can be identified in the fault indication menu.
[O] Pump 5 is not operating.
The reason can be found in the pump status menu.
[–] Pump 7 is allocated to a zone, but it has not yet been con-
nected to the PMU 2000 or the electricity supply to the pump
was never switched on.
[ ]
Pump 8 has not been allocated to any zone.
A point between two pump numbers indicates that these pumps
have been connected to a PCU 2000. The display shows that
pumps 1, 2, 3 and 4 have been connected to a PCU 2000.
To find the units in the Control 2000 S, see the wiring diagram
and the mechanical layout.
