This is the current valve
position expressed as a
percent of the valve
control signal output.
This example shows a
setting of 20.1% of the
valve control signal
output.
The BASE valve position
is expressed as a percent
of the valve control signal
output.
In this example, BASE is
the parameter which is
selected for editing, and
is currently set at 15.5%.
This indicates which of the
four possible recipes is
selected for editing (in this
case, it is recipe 2).

This is the pressure reading from the
gauge on the control channel.
Figure 46: Adjusting the Base Valve Position
Base is a valve control parameter that is expressed as a percent of the valve control signal output.
A Base setting of 20 means the valve control signal output should not go below 20% of the full
open output. In effect, this means the valve should remain at least 20% open.
For solenoid valves, the Base parameter is frequently adjusted to the point just below where the
valve begins to open.
Note
The Base parameter can override the Softstart parameter (Code 13x in the
Operation in Setup Mode chapter).
