2.1.1.9 LPM control (marker #9a-9b of image 2.1.1)
The LPM controls allows a range of 10 to 450 liters per minute flow to be requested.
There are two such controls one for each servo unit. If the servo unit is not currently selected then the control will be grayed out and no adjustment can be made.
Each digit is individually controlled and no interaction occurs between digits.
If the program detects an out of range condition then the display ( marker #2) background changes from green to red and the COMMIT button deactivates and displays “INVALID” whereby the operator must change the value to a valid range.
