Section 4.3 Tonnage Alarms/Stop Conditions
The Main Tonnage Monitor screen provides a status indication for each channel. This message indicates
any tonnage alarm or error condition that has occurred and under normal operating conditions should
show "Status: OK". If a tonnage alarm occurs, the message will change to reflect the FIRST alarm
detected on that channel during the stroke.
Section 4.3.1 Low Alarm
One of the messages listed below in the Channel Status indicates that the maximum tonnage recorded
during the last stroke did not reach the Low Limit setting.
"Low Pk Alarm " Tonnage did not reach the Low Limit set in Peak Tonnage.
"Low Dw1 Alarm"
Tonnage did not reach the Low Limit set in Data Window #1.
"Low Dw2 Alarm" Tonnage did not reach the Low Limit set in Data Window #2.
"Low Dw3 Alarm" Tonnage did not reach the Low Limit set in Data Window #3.
"Low Dw4 Alarm" Tonnage did not reach the Low Limit set in Data Window #4.
This limit is not checked and the message will not appear until the press reaches the end of the working
portion of the stroke. When the condition is detected on any channel, a Top 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.
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 Top Stop".
Section 4.3.2 High Peak Alarm
A Channel Status message "High Pk Alarm" indicates that the maximum tonnage recorded during the
last stroke exceeded the High Limit setting in Peak Tonnage.
If the tonnage monitor has been configured to generate Top Stops for High Peak alarms, this limit is not
checked and the message will not appear until the press reaches the end of the working portion of the
stroke. When the condition is detected on any channel, a Top 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.
If the tonnage monitor has been configured to generate Cycle Stops for High Peak alarms, this condition
causes an immediate stop signal to be 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.
If the tonnage monitor has been configured to generate a Cycle Stop and Turn Off Hydraulic Overload
outputs for a High Peak alarm, the press control will stop immediately and turn off its' hydraulic pump
and cylinder outputs. Further stroking is prevented until the alarm is reset in the tonnage monitor and
the press is Inched to the top of the stroke. Normal stroking is allowed only after the hydraulic overload
is pumped back up.
