violates the low limits. When this setting is “Yes”, the tonnage monitor will automatically bypass the
low limits while in a setup mode. This happens with no operator intervention and clears itself when
going back to a production mode. While in setup mode, the low limits are clearly indicated as off in
each channel status line with “Setup Mode Low Lim OFF” displayed in yellow. The benefit of this
setting is that high and reverse limits are not bypassed, thus providing greater machine protection, and
that the operator does not have to remember to turn the low limits back on when going to production
mode.

The alarm counters that are displayed in the Tonnage Monitor Diagnostics screen (see section 3.3 on

Changes can be made to the tonnage monitor calibration numbers (gain) with the RUN/PROG keyed
selector switch in the PROG position. Position the editing cursor onto the desired calibration number
and use the numeric keypad to enter the desired value. The press can be operated with the selector
switch in the RUN position and will update the actual peak tonnage measured each stroke. See section 7
on page 63 for calibration procedures.
