Valve Menu

Main Menu → Service Menu → Diagnostics Menu → Valve Menu
The Valve Menu allows the user to observe the instrument controlled switching of the valves. If the
valve is On it means the valve is energised. When a three way valve is in the On state it will now be in
the NC (normally closed) position as shown in the plumbing schematic. When the Valve Sequencing is
Disabled, the user has the ability to turn the valve Off and On manually. It is recommended that the
Valve Menu be used by a trained technician following the plumbing schematic (refer to Section 9.5).
Note: When interpreting the information below regarding the flow path through the valve note
that (NC = Normally Closed), (NO = Normally Open) and (C = Common).
