Warning!
While in AUTO SETUP mode, the tonnage monitor module will ignore any
high, low, or reverse alarm. Only machine rating alarms are active. For
progressive dies, material must complete its progression through all stations
before beginning Auto Setup.
uppermost vertical softkey) should read “CHANGE LOW LIMIT”. Press this softkey to enter numeric
entry mode. Enter the new limit with the numeric keypad and press the ENT key to set the limit. The
low limit MUST be less than the high limit for that channel and view! Note that setting this value to
zero effectively disables it.
Section 4.2.2.3
Setting Reverse Limits
To set a reverse limit, first set the view to “peak reverse” as shown in Figure 4.4. Place the data entry
cursor on a reverse limit setpoint (see “n” in Figure 4.4) using the up, down, left, and right arrow keys.
Softkey 1 (The uppermost vertical softkey) should read “CHANGE REV LIMIT”. Press this softkey to
enter numeric entry mode. Enter the new limit with the numeric keypad and press the ENT key to set the
limit.
Section 4.2.2.4
Automatically Setting Limits
The AUTO-SETUP softkey initiates an automatic calculation of the present tonnage limits. Like
manually setting limits, this is a restricted function. The operator must have access via RUN/PROG Key
or access code depending on how the system has been configured (See Section 2 for access configuration
details). When this key is pressed, a box will appear which allows the operator to enter a Percent
Tolerance (percent of machine rating of each channel) which is applied to the peak tonnage recorded
during the automatic setup process. A tolerance from 1 to 30 percent of the channel rating is added to
the highest tonnage recorded in the sixteen (16) successive strokes made in the auto setup mode in order
to calculate the High Limit. The tolerance is subtracted from the lowest peak tonnage recorded during
the procedure in order to calculate the Low Limit. The tolerance is subtracted from the most negative
peak tonnage recorded in order to calculate the Reverse Limit.
To begin the automatic setup procedure the operator must remain in the tonnage monitor screen, switch
the RUN/PROG keyed selector switch to the RUN position, and make sixteen strokes in order to allow
the tonnage monitor to measure the typical variation of the process. The actual tonnages and number of
strokes remaining are automatically updated each stroke. A maximum of 60 seconds is allowed between
strokes or the setup procedure will automatically abort and leave the present limits unchanged. After the
last stroke, the tonnage monitor module will automatically exit the setup mode and calculate the tonnage
limits. Normal operation will continue with the new limits. Low limits and reverse limits are updated
even if turned OFF. Data window limits are not updated if the data window is turned OFF. The
automatic setup procedure can be aborted at any time before the sixteenth stroke by pressing the EXIT
softkey. The previously entered limits will then remain in effect.
