6.6 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 suction lines
• for large suction lift.
In the "Setup > SlowMode" menu, the speed of the
suction stroke can be reduced to 50 % or 25 %.
Fig. 32 SlowMode menu
Caution
Enabling the ' SlowMode ' function
reduces the maximum dosing flow of
the pump to the set percentage value!
