6.1
Note: If the Tonnage Monitor Module is installed in the OmniLink II as an option after the system
has been in operation, there may be job setups stored in the press control that have not been stored in
the Tonnage Monitor Module. This situation might also arise if a Tonnage Monitor Module is
swapped from one OmniLink II control to another. In this case, when one of those previously stored
jobs is recalled from memory by the operator, the Tonnage Monitor Module will not be able to find
any information stored. If this occurs a message will be displayed on the job setup screen which reads
"No Tonnage Monitor Settings". In this situation the operator should select to continue the recall
operation, all other press control parameters will be recalled. The tonnage monitor settings will
remain unchanged from what they were prior to the recall.
The operator MUST program the correct
tonnage monitor settings for the current job . Once the tonnage monitor settings are set correctly for
this job, the operator should store this job with the same job number and description. This will store
the tonnage monitor settings under this job number for recall later.
Section 6 Job Setups
In the OmniLink II, all pertinent information for the current job such as programmable limit switch
setpoints and automatic feed settings can be stored for later use as a block of information called a "job
setup". Since this programmed data may change from job to job or as machine dies are changed, saving
a job setup prevents the operator from having to manually change all this information when dies are
changed. The operator can simply recall the appropriate job setup which he previously stored and the
press is ready to run. The OmniLink II has memory capability for storing 500 job setups. Information
on storing, recalling, or erasing job setups is in the OmniLink II manual.
The Tonnage Monitor Module will also store or recall all its pertinent data when the operator stores or
recalls a job setup. This includes all programmed information such as, the low limits, high limits,
reverse limits, data window states (ON/OFF), data window angles, and reference waveforms. The
operator need not perform any additional or separate operations to store or recall tonnage monitor
information; simply follow the standard procedure for job setups listed in the OmniLink II manual and
the setup change is done automatically in the Tonnage Monitor Module.
If a tonnage monitor module is installed after an OmniLink II has been in operation and job setups have
been stored in the press control, the jobs will not exist in the tonnage monitor module. If a job is
recalled, the tonnage monitor will detect that the setup does not exist and the operator terminal will
display the message "No Tonnage Monitor Settings". In this situation the operator should select to
continue the recall operation, all other press control parameters will be recalled and the present settings
in the tonnage monitor will not be changed. Once the tonnage monitor settings are set correctly for this
job, the operator should store this job with the same job number and description. This will store the
tonnage monitor settings under this job number for recall later.
Section 6.1 New Die Installation
In normal operating conditions, the job recall function is used to load the tonnage monitor module with
the correct low, high, and reverse limits for the die being used. However, when a new die is installed in
the machine, the tonnage requirements may not be defined. The limits presently in the tonnage monitor
remain in effect and may cause tonnage alarms when the press is run. While the BYPASS feature can be
used to prevent tonnage alarms from occurring, it will bypass ALL alarms (except machine rating
