11. Lower the set-output value in DYC09-12 corresponding to the
selected clamp close pressure valve to a safe level.
12. Disable set-output operation. Toggle DYC01-B08 (B34/392) to 0.
13. Download your changes in FCC, SCC, and TCC to the QDC module.
Important: If downloading from your programming terminal, download
FCC, SCC, TCC, and CPC in that order (chapter 4).

Test Valve Linearity with a Clamp Close Pressure Profile
1. Jog your clamp to the full open position.
2. Enable the first clamp close profile by setting DYC02-B00 (B34/400)
to 1. The clamp should move from its start position through clamp
close and low pressure close profiles. If no motion, verify that:
- no clamp overtravel alarms are set. The QDC module inhibits
clamp close if SYS07-B00 through -B05 are set
- no programming error codes exist in SYS61 and SYS62
3. At completion of clamp close, observe the pressure reported for first
clamp close segment 2 CPS13 (N43:665). If it is not approximately
equal to the setpoint you entered in CPC13, then check:
- was your valve and solenoid alignment the same for clamp close
profile execution and clamp close action in set-output?
If the observed pressure CPS13 is still not within 20% of CPC13, your
pressure valve is not linear over the desired range. Correct as follows:
If: And Your Selected
Valve is:
Then change FCC44
(N43:40) as follows:
CPS13 was less than CPC13 Direct Acting Increase in 5% steps
Reverse Acting Decrease in 5% steps
CPS13 was more than
CPC13
Direct Acting Decrease in 5% steps
Reverse Acting Increase in 5% steps
