Section 4.3.5 Machine Rating Alarm
A Channel Status message "Machine Rating" indicates that the maximum forward tonnage recorded
during the last stroke exceeded 125 % of channel rating. When the condition is detected on any channel,
a Cycle Stop is provided to the press control. This stop signal remains in effect and further stroking
prevented until the alarm is RESET.
The Module Status in the bottom of the Main Tonnage Monitor screen will indicate "Tonnage Alarm".
The Present Running Status in the Press Control screen will indicate "Tonnage Cycle Stop".
Section 4.3.6 TOTAL Alarm/Stop Condition
This alarm condition indicates that the maximum TOTAL tonnage exceeded the capacity of the machine
at the height in the stroke at which it occurred. It is the only limit applied to the total tonnage and may
or may not coincide with any channel alarm. When the condition is detected on the total tonnage, a
Cycle Stop is provided to the press control. This stop signal remains in effect and further stroking
prevented until the alarm is reset by pressing the RESET ERROR softkey.
This alarm will only occur if the tonnage monitor is configured to derate the total tonnage capacity. The
machine rating is specified by the press manufacturer at a specific height off the bottom of the stroke
(for example .25 inches). Above this height the total tonnage available is limited by the torque of the
crankshaft and will decrease as the height off the bottom at which the tonnage occurs increases (see
section 5.2 for how this derate curve is programmed).
The Module Status in the bottom of the Main Tonnage Monitor screen will indicate "TOTAL Alarm".
The Present Running Status in the Press Control screen will indicate "Tonnage Cycle Stop".
