9. Copy this observed maximum pressure from SYS26 (N40:178) into
FOC42, SOC42, TOC42, and OSC42 (N43:338, 398, 458, and 518),
the maximum pressure control limits.
10. While maintaining this maximum pressure, observe the actual
set-output value in the SYS41-44 (N40:193-196) that corresponds to
your selected clamp open pressure valve. Copy this value into
FOC44, SOC44, TOC44, and OSC44 (N43:340, 400, 460, and 520),
the selected pressure valve, output for maximum.
11. Lower the set-output value in DYC09-12 corresponding to the
selected clamp open pressure valve to a safe level.
12. Disable set-output by transitioning DYC01-B08 (B34/392) to 0.
13. Download the changes FOC, SOC, TOC, OSC to the QDC module.
Important: If downloading from your programming terminal, you must
download FOC, SOC, TOC, OSC, and OPC in that order (chapter 4).

Test Valve Linearity with a Clamp Open Pressure Profile
1. Jog your clamp to the fully open position.
2. Enable first clamp open by setting DYC02-B10 (B34/410) = 1. The
clamp should move from its start position through the first clamp
open and open slow profiles. If no motion, verify that:
- no overtravel alarms are set. The QDC module inhibits clamp
open if SYS07-B00 through SYS07-B05 are set
- no programming error codes exist in SYS61 and SYS62
3. Upon completion of clamp open, observe the pressure reported for 1st
clamp open segment 2 (OPS13, N43:721). If the observed pressure is
not about equal to the setpoint you entered in OPC13, then check:
- was your valve and solenoid alignment the same for clamp open
profile execution and clamp open action in set-output?
If the observed pressure OPS13 is still not within 20% of OPC13, your
pressure is not linear over the desired range. Correct as follows:
