5.

Record this signal level on line 15 for MCC33 (should be at
minimum signal if you zeroed your pressure sensor in step 4).

ATTENTION: Use extreme caution during the next steps
because you stress the hydraulic system to its maximum rated
pressure. Loose fittings or faulty components could fail, causing
possible damage to equipment and/or injury to personnel.

6.

Re-torque all hydraulic connections and joints before proceeding.

7.

Boost system pressure to obtain maximum pressure at the clamp.

Obtain maximum system pressure by positioning the clamp at full
open while keeping the clamp open valve in the maximum open
position. This forces the cylinder to press against mechanical limits
of its travel and builds maximum system pressure. Also, you may
wish to move the clamp to its full forward (mold close) position, and
allow full system pressure to force the mold closed.

8.

Read the clamp pressure gauge. Do this while the clamp is
mechanically bound from moving.

9.

Record this maximum pressure on line 14 for MCC32.

10.

With your programming terminal, read the signal level returned in
SYS36 (N40:188) from your pressure sensor. You may wish to span
your pressure sensor at this time.

11.

Record this signal level on line 16 for MCC34.

12.

Release pressure.

You may now download your adjusted values to the QDC module using
the MCC download procedure presented earlier in the chapter.
