Valve Actuation Of Gc- Controlled Valves - HP 5890 SERIES II Service Manual

Valve Actuation of GC- Controlled Valves

(Operation of one or two 120- volt solenoid valves)
Activation of up to two valve solenoids (designated as Purge A or Purge B) may occur in either of two
ways. The operator may switch the valves manually whenever it is desirable via keyboard entry, or
more conveniently, the valves can be switched ON once and OFF once during a run via the HP 5890' s
timed events table.
If the valve is already in the position where a command instructs it to switch, no action
will occur.
The designated channels (A or B) are determined solely by the wiring connections to the valve box.
