Set the setpoint in units of the feedback sensor.
In control mode Open loop, the setpoint is set in % of the
maximum performance. The setting range will lie between the
min. and max. curves. See fig. 44.
In all other control modes except proportional differential
pressure, the setting range is equal to the sensor measuring
range. See fig. 45.
In control mode Proportional differential pressure, the setting
range is equal to 25 % to 90 % of max. head. See fig. 46.
If the pump is connected to an external setpoint signal, the value
in this display will be the maximum value of the external setpoint
signal. See section 13.2 External setpoint.
10.5.2 Operating mode (1.2)
Set one of the following operating modes:
• Normal (duty)

• Max.
The operating modes can be set without changing the setpoint
setting.
10.5.3 Fault indications
Faults may result in two types of indication: Alarm or warning.
An "alarm" will activate an alarm indication in CUE and cause
the pump to change operating mode, typically to stop. However,
for some faults resulting in alarm, the pump is set to continue
operating even if there is an alarm.
A "warning" will activate a warning indication in CUE, but the
pump will not change operating or control mode.
Alarm (1.3)

function.

power supply after the alarm occurred.
Warning log (1.10-1.14)

appear in the warning log. "Warning log 1" shows the latest fault,
