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.
ATTENTION: If the ram (screw), clamp, and/or ejectors are
not disconnected from the hydraulic circuit, be sure that they are
fully retracted with their hydraulics aligned in the retract
position. This forces the cylinders to press against the
mechanical limits of travel and builds max system pressure.
Otherwise, they could suddenly move, 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 maximum.
8.
Read the system pressure gauge. Do this while the ram (screw) is
mechanically bound from moving.
9.
Record this maximum pressure on line 6 for MCC58.
10.
With your programming terminal, read the signal level returned in
SYS34 (N40:186) from your pressure sensor.
Important: If your pressure sensor has a potentiometer to set the span
(linear resolution), do so now.
11.
Record this signal level on line 8 for MCC60.
12.
Release pressure.
You may now download your adjusted values to the QDC module using
the MCC download procedure presented earlier in this chapter.
