4. Enable set-output by changing DYC01-B08 (B34/392) from 0 to 1.
This forces the QDC module to apply the values in DYC09-12
directly to its outputs 1-4, respectively.
5. Adjust the set-output value DYC09-12 (N40:121-124) that
corresponds to the selected clamp close pressure valve, and observe
the pressure reported in SYS26 (N40:178).
For a bi-directional valve with a spool offset:
If this pressure is greater than zero, adjust the set-output value to
the clamp close pressure valve to obtain zero pressure. Stop the
adjustments when you observe the smallest pressure attainable.
For a uni-directional valve with no response at low signal level:
If this pressure is zero, adjust the set-output value to the clamp
close pressure valve until the observed pressure just exceeds zero.
Then re-adjust this value until you just observe zero again.
For a uni-directional valve with a pressure actual greater than
zero but with zero output to the valve: This is lowest pressure.
6. Once you are satisfied that you obtained the lowest possible pressure
or the highest possible signal at zero pressure, copy the pressure
observed in SYS26 (N40:178) into FCC41, SCC41, and TCC41
(N43:37, N43:97, and N43:157), the clamp close minimum pressure
control limit.
7. While maintaining this minimum pressure, observe the actual
set-output value in SYS41-44 (N40:193-196) that corresponds to your
clamp close pressure valve. Copy this value into FCC43, SCC43, and
TCC43 (N43:39, 99, and 159), the selected clamp close pressure
valve output for minimum.
8. Change the set-output value in DYC09-12 (N40:121-124) that
corresponds to the clamp close pressure valve by 50%, and then in
5% steps while observing the clamp pressure in SYS26 (N40:178).
Stop adjusting it when the observed pressure no longer increases with
an increase in set-output value. The pressure in SYS26 (N40:178) is
now the maximum attainable clamp close pressure.
9. Copy this observed pressure from SYS26 (N40:178) into FCC42,
SCC42, and TCC42 (N43:38, 98, and 158), the maximum clamp
close pressure control limits.
10. While maintaining this maximum pressure, observe the actual
set-output value in SYS41-44 (N40:193-196) that corresponds to your
selected clamp close pressure valve. Copy this value into FCC44,
SCC44, and TCC44 (N43:40, 100, and 160), the selected clamp close
pressure valve, output for maximum.
