7.5. Starting the pump
Press the “START” button.
The unit will begin pumping. The triangle symbol will appear in
the display.
An externally driven pump will start only if the external pump
signals allow a pump start-up (see Chapter 8).
7.6. Interrupting a pumping operation
Press the “START” button.
The pumping operation is interrupted. The pause symbol will
appear in the display.
When the pump is restarted from “Pause” condition, the
interrupted pumping operation is continued.
When in “Pause” condition, the pump responds to external
control signals.
7.7. Stopping the pumping operation
Press the “STOP” button,
The pumping operation is interrupted. The pause symbol will
appear in the display.
Press the “STOP” button again.
The pump will now switch to “Stop” condition, and reset the time
counter and volumeter.
The first time the user presses the “STOP” button puts the
working pump into Pause condition.
The pump goes into “Stop” condition only when the “STOP”
button is pressed for the second time.
Stopping the pump with the “STOP” button is called a “master
stop”. The pump can then only be restarted manually.
For a pump operated by external signals, the master stop first
has to be manually cancelled by pressing the “START” button.
A reset at digital input 2 cancels the master stop, and the pump
can then be started externally.
