7.5 Analog output
Fig. 34 Configure analog output
The analog output of the pump is parametrised in the
"Setup > Analog output" menu. The following
settings are possible:
* Output signal is based on motor speed and pump
status (target flow).
** Signal has same analog scaling as the current
analog input signal. See 7.4.3 Analog 0/4-20 mA.
Wiring diagram see section 5.3 Electrical
connection.
7.6 SlowMode
When the "SlowMode" function is enabled, the
pump slows down the suction stroke. The function is
enabled in the "Setup > SlowMode" menu and is
used to prevent cavitation in the following cases:
• for dosing media with a high viscosity
• for degassing dosing media
• for long inlet lines
• for large suction lift.
In the "Setup > SlowMode" menu, the speed of the
suction stroke can be reduced to 50 % or 25 %.
