Principles of Operation
4.1.2 Pump 1 and Valve 1 Buttons
The Pump 1 buttons allows you to turn the pump on or off in manual mode. Likewise, the
Valve 1 buttons allow you to open or close valve 1. The pertinent lamps will indicate the
current condition:
•
The
green lights
will indicate that the pump is running or the valve is open.
• The
red lights
will indicate that the pump is off or the valve is closed.
4.1.3 Pump 2 and Valve 2 Buttons
The Pump 2 and Valve 2 buttons have the same function as the Pump 1 / Valve 1
described in the previous section, the only difference is that they affect Pump 2 and
Valve 2.
4.1.4 Valve 3 Buttons
The Valve 3 buttons are intended for future extensions and presently are not used.
When you press the buttons you will hear a click, but no function will be performed.
4.2 Pumps and Valves in Manual Mode
There are several pump and valve configurations available in manual mode:
•
Pump 1 on together with Valve 1 opened,
• Pump 2 on with Valve 2 opened, or
• Both pumps on with both valves opened.
In manual mode the condition of the pumping system is not monitored, thus when a
pump or valve is not working correctly the system will not react.
NOTICE
Using the pump in manual mode
When using a pump in manual mode it is possible that a return flow of air into the
pump line occurs.

Always switch the pump on first, then wait 10 to 15 seconds before you open the
associated valve.

Before switching a pump off, always close the associated valve first!
