Remote fluid recovery (Universal and Un models
without relay modules)
It is possible to run the pump in reverse and recover fluid automatically in the analog 4-
20mA mode. To achieve this, it is necessary to enable remote fluid recovery functionality.
To enable this position the selection bar over fluid recovery in the mode menu and press
the
SETTINGS
function key.
Select
ENABLE
to turn this functionality on. The reverse process can be used to switch the
function off.
When this function is enabled, the pump operation can be reversed in analog 4-20mA mode
by applying minimum 5V to maximum 24V to pin 5 of the pump input. The pump will
operate at a reversed set speed proportional to the 4-20mA input applied to pin 3.
