OPERATION
When communication between the R100 and the Hydro Multi-E
has been established, the first display in this menu will appear.
10.1.1 Setpoint

Actual value
Set the setpoint in this display.
In normal operating mode (factory setting), the setting range is

One of the following operating modes can be selected:
• Stop
• Max. (max. curve).
10.1.2 Operating mode
Set one of the following operating modes:
• Stop
• Normal (duty)
• Max.
The operating modes can be set without changing the setpoint
setting.
10.1.3 Fault indications
In case of a fault, the cause will appear in this display.
Possible causes:
• Too high motor temperature
• Undervoltage
• Overvoltage
• Too many restarts (after faults)
• Overload
• Sensor signal outside signal range (only 4-20 mA)
• External fault
• Dry running (emergency operation only)
• Other fault.
A fault indication can be reset in this display if the cause of the
fault has disappeared.
10.1.4 Alarm log
In case of faults, the last five fault indications will appear in the
alarm log. "Alarm log 1" shows the latest fault, "Alarm log 2"
shows the latest fault but one, etc.
The example above gives this information:
• The fault indication "Undervoltage" for pump 1 (No. 1).
• The fault code (40).
• The number of minutes the Hydro Multi-E has been connected
to the power supply after the fault occurred, 8 min.
10.2 Menu STATUS
The displays appearing in this menu are status displays only. It is
not possible to change or set values.
The displayed values are the values that applied when the last
communication between the Hydro Multi-E and the R100 took
place. If a status value is to be updated, point the R100 at the
control panel and press [OK].
If a parameter, e.g. speed, should be called up continuously,
press [OK] constantly during the period in which the parameter in
question should be monitored.
The tolerance of the displayed value is stated under each display.
The tolerances are stated as a guide in % of the maximum values
of the parameters.
10.2.1 Actual setpoint
Tolerance: ± 2 %
This display shows the actual setpoint.
It is not possible to connect an external setpoint signal.
10.2.2 Operating mode
This display shows the actual operating mode (Stop, Normal
(duty) or Max.). Furthermore, it shows where this operating mode
was selected (R100, Pump, Bus, External or Stop func.).
For further details about the stop function, see section 10.3.5.
