The setpoint to which the pump controls is specified according to "Control settings" [" 160]
section.
The "Cable break detection" function is active.
An analogue signal smaller than 1 V is recognised as a cable break.
A set emergency operation speed is then used as emergency operation. For this, the emer-
gency operation must be set to "Pump ON" in the menu "Control Setting – Emergency Oper-
ation [" 163]". If the emergency operation is set to "Pump OFF", the motor of the pump is
switched off when a cable break is detected.

Setting of an on-site differential pressure sensor:
If a differential pressure sensor is set up on-site at the analogue input AI1 (for instance at a
pump version R1), the pressure sensor range and the pressure sensor position must be set at
the analogue input AI1 (see Fig. 69 Analog input AI1). Possible pressure sensor positions:
• Pump flange
• Standard-compliant position
NOTICE
Recommendation: Set the pressure sensor range to be set at least as high
as the maximum possible delivery head of the respective pump type.
The pressure sensor range must be configured in the "Pressure sensor
range" menu for this purpose. (Fig. 69 Menu analogue input AI1 and Fig. 71
Pressure sensor range AI1)
Example:
If the pump type has a maximum delivery head of 20 m, the differential pressure sensor to be
connected must be capable of at least 2.0 bar (approx. 20 m). If a differential pressure sensor
with, for example, 4.0 bar is connected, the differential pressure range must be set to 4.0 bar.
The appropriate signal type for the differential pressure sensor to be connected must always
be selected. In this case 2 ... 10 V or 4 ... 20 mA.
NOTICE
The differential pressure range to be set must always be set to the nominal
maximum value of the connected differential pressure sensor. The nominal
maximum value corresponds to the sensor value 100 %. The value must be
read from the rating plate of the differential pressure sensor. This is the
only way to ensure that the pump controls correctly.
