Valve control
Procedure: Controlling valves from the keyboard
Valves (except multiposition valves) have two positions controlled by the [On]
and [Off] keys. The keyboard commands for two-position valves are:
[Valve #] <scroll to the valve> [On](rotates valve to one stop)
and
[Valve #] <scroll to the valve> [Off](rotates valve to the other stop)
From the run or clock time tables
The Valve On and Valve Off commands can be run time or clock time
programmed. See chapter 7 for more information.
If a valve is rotated by a run time program, it is not automatically returned to its
initial position at the end of the run. You must program this reset operation
yourself.
