b. Press the cut buttons, and while reading the pressure on the main gauge (front
gauge), release them. The gauge should read between 400-600 psi as the clamp is
going up. There should be no clamp movement until the knife is stopped in the up
position.
To Adjust:
a. Remove the protective cap and loosen the lock nut on the clamp up sequence valve.
b. Make a cut, then release the buttons. Read the main gauge as the clamp is
returning. Adjust the valve for a reading of 400-600 psi.
c. Tighten the lock nut while holding the hex wrench in place and replace the protective
cap.
4. Electronic Clamp Pressure Setting (TC Console) – 400min/1,400max psi
The electronic clamping control allows the convenience of changing the clamp pressure at
the control console, as well as the ability to program different clamp pressure settings within
programmed jobs. The clamp pressure is controlled by use of a slide bar on the TC touch
screen located at the lower left corner of the screen. A number between 0 and 15 will be
displayed, indicating the current pressure setting (0 being the lowest, 15 the highest). To
adjust the actual clamp pressures at the minimum (0) and maximum (15) settings, follow the
procedure below:
Adjustment of the Electronic Valve:
a. On the TC touch screen, select the Maintenance pull-down menu then choose Setup.
Then select the Service Info tab, and in the box for Enable Tabs Code, enter 6125.
Now select the Hydraulic Settings tab. The screen should look similar to Figure 24
