Load Initial Configuration Values

Chapter 7

7-36

Determine Output for Minimum values as follows:

0 (0%) for uni-directional direct acting valves
5000 (50%) for bi-directional valves
9999 (100%) for uni-directional reverse acting valves

If your selected

pressure valve is:

Then the value in word 43

should be:

And during the profile, the QDC

module does NOT drive the valve

with a % output:

Direct Acting

less than the value in word 44

less than the value in word 43

Reverse Acting

greater than the value in word 44 greater than the value in word 43

Enter initial Output for Minimum values on corresponding worksheets.

Selected Pressure Valve, Output for Maximum

(FCC44, SCC44, TCC44, LPC44, INC44, PKC44, HDC44, PLC44, FOC44, SOC44,
TOC44, OSC44)

The QDC module uses this word with the Maximum Pressure Control
Limit (word 42) above. Enter the %-signal output that the QDC module
uses to drive the selected pressure valve for maximum profile pressure.
The QDC expects a pressure equal to word 42 when setting the selected
pressure valve to this percentage output.

Determine Output for Maximum values as follows:

9999 (100%) for uni-directional direct acting valves
0 (0%) or 9999 (100%) for bi-directional valves depending on direction
0 (0%) for uni-directional reverse acting valves

If your selected

pressure valve is:

Then the value in word 44

should be:

And during the profile, the QDC

module does NOT drive the valve

with a % output:

Direct Acting

greater than the value in word 43 greater than the value in word 44

Reverse Acting

less than the value in word 43

less than the value in word 44

Enter initial Output for Maximum values on corresponding worksheets.
