MARINER RS SCREENS
MONITOR SCREEN
The monitor screen displays the tonnages,
strokes per minute, parts count, alarm
status, and alarm settings.
Variations of the monitor screen include
two, and four channel screens.
The four- channel screen (Figure B1)
contains five tonnage meter displays.
Each corner meter displays the tonnage
reading corresponding to the channel, and
the center meter displays the sum of the
four channels.
The two-channel screen (Figure B2)
contains two tonnage meters and a total
tons meter.
Figure B1 – 4 CHANNEL MONITOR SCREEN

TREND LIGHTS
All monitor screens contain a set of 9
“LED display trend lights” located to the
left or right of each tonnage meter. These
lights give the following alarm indications
corresponding to that particular channel:
Capacity Alarm: Top LED red
Hi Tolerance (Track or Trend)
Alarm: Top 4 LED’s
Lo Tolerance (Track or Trend)
Alarm: Bottom 4 LED’s

The trend lights also give an indication of
peak tonnage variation during the part
making process. Tonnage values changing
too high (or low) over (or under) the
sample value, cause the LED lights to light up
Figure B2– 2 CHANNEL MONITOR SCREEN
above (or below) the center green LED. If the
peak tonnage reaches the tolerance limits, a trend alarm will be triggered. Trend lights step (from center
green, green, yellow, yellow, and red) in 25% increments of the difference between the sample and the
tolerance limit. The tolerance limits are the boundaries set by the operator (high and low tolerance settings
in the jobs screen) as the percentage (or tons) above and below the sample value to provide part quality
control.
11
MarinerRS Operating Instructions

MONITOR SETTINGS/READINGS
Each monitor screen displays the strokes per minute (SPM), and parts count. Parts Batch is a value (set in
jobs/settings screen) that stops the press when the parts count value reaches the parts batch value.
The following settings are displayed adjacent to each tonnage meter:
HCAP: Capacity alarm value in tons
+TOL: High Tolerance (Trend/Track Alarm) setting in tons or percent
SAM: Sample Value – “learned” during trending in tons
-TOL: Low Tolerance (Trend/Track Alarm) setting in tons or percent
REV: Reverse Load in tons
At the top of the monitor screen, the corresponding sequence name and present job name are displayed.
ALARMS HISTORY
In case of tonnage alarm, this indicator will flash the message between “Alarm” and “Click here for Details”
Click this indicator anytime to access details of the alarm message including previous alarms.
BUTTONS
At the bottom of the monitor screen are eight buttons activated when pressed. The left seven buttons may be
“locked out” in the Supervisor screen to prevent operator use.
Sequence Navigation button - Press the arrow buttons by the sequence name to navigate between
different sequences. In general, each sequence represents one press or slide of up to four channels.
Reset Button – Press button to reset any alarms, which caused the relay to trip and stop the press.
Alarm Setup – Press to view or change Jobs settings
Mode Buttons (CAL, SETUP, MONITOR) – Press button to change mode. System will be in one
of the three modes: Calibrate, Setup, Monitor Parts (white button indicates present mode). More than
one white button is an illegal mode, press a button to activate desired mode.

MarinerRS Operating Instructions

CURRENT ALARM SETTINGS SCREEN
This screen (Figure B3) allows the operator to change alarm settings for current job.
Keypad
If you click on any green colored numeric
display, a keypad will pop up so that you
can make entry using touch screen.
Job
This displays the current job name that
which was downloaded from the job recipe.
Sequence Name
The area in the top left corner displays the
current sequence name being viewed.
High Capacity
Capacity alarms are active in setup and
monitor-parts modes (not calibrate) usually
for press protection. The typical values
Figure B3 – CURRENT ALARM SETTINGS SCREEN
entered are press capacity divided by number of
channels. For example, on a 500 Ton press using
four channels, capacities are set at 125 tons per channel.
+ / - TOL (Tolerance Alarm Values)
Tolerance alarm settings correlate to both trend and tracking alarm settings. Select and enter valid range (050) if it is in percent, (0-255) if it is in Ton. These alarms are active in “monitor parts” mode only and are
based off of the “learned” sample value. Entering a “0” into the keypad turns the tolerance (high or low) off
for that particular alarm.
Trend Alarms
Trend alarms, are valid in “monitor-parts” mode only, and are base off of the “sample peak” taken during
the “learn cycle”. Trend alarms provide a “parts quality” type of feature, triggering alarms if the peak
tonnage goes out of range of the tolerance.
Tracking Alarms
Tracking alarms, are valid in “monitor-parts” mode only, and are based off of the “sample curve” taken
during the “learn cycle”. Track alarms provide a thorough “parts quality” type of feature, because
monitoring continues throughout the press stroke (based on the look window settings in the “Other Settings”
screen).
Delta Track
The delta track feature pertains to the filtering of tracking alarms, and helps to avoid “nuisance” type of
alarms. The filtering occurs during sudden force change within the press stroke. Delta track filtering can be
seen in the wave screen, where high slopes of the sample signature (along with the tracking bands) get
filtered during relatively small portions of the stroke.
13
MarinerRS Operating Instructions

Press Curve
Press Curve alarms are valid in “setup” mode only, and provide press protection. Data points are retrieved
from the press manufacturer, and activated in the “press curve” screen. These points represent tonnage
limitations per angle of the press stroke. During the part process, if the tonnage exceeds the press curve
limitation at any specific angle, a press curve alarm is triggered. Press curve may be viewed in the “wave”
screen.
AMP Track
The AMP track is another type of filtering to avoid “nuisance” alarms. The filtering consists of masking
points where the variance between samples surpasses the alarm limit.
Tons/Percent
Tolerance alarms run in either tons or percent, which is selected in the jobs screen. At loads less than peak
(throughout the stroke), tolerance in the percent mode is less than tons mode. This can be seen in the “wave”
screen when comparing tons to percent.
Learning Cycle
The learning cycles (selectable 2, 4, 8, or 16) are the number of counts taken during the “sample” cycle of
the system. Sampling occurs when the operator enters monitor- parts mode from setup-mode. After the
number of press strokes reaches the set learning cycles, the module takes an average tonnage (and wave) per
channel. This average is referred to as the sample, and becomes the benchmark in which the high and low
tolerances are based
Alarm Window
The operator may choose to confine the alarm window to avoid possible nuisance alarms. Start and end
angles must be within the look window. Select and enter values in keypad.
Low Alarm Inhibit Cycle
The low alarm inhibit cycle is the number of times that a less than low trend sample peak will be ignored
before firing an alarm.
Look Window
The look window includes the start and end angles of the press, where alarm monitoring is active. The
optimal settings are to start the look window at die contact with the stock, and end the look window at stock
release. View waveform screen to verify desired look window settings (default settings are 60-283 degrees).
To change start angle, select look window start angle and enter 30-285. Select end angle (1-6 choices
depending on start angle value) below start angle reading, which is highlighted in green.
Tracking Threshold Set
The tracking threshold set feature sets a “bottom-line” when monitoring the tracking alarm. In Figure B3,
the tracking threshold set is ten percent. This means that the tracking alarm will only monitored above the
ten percent threshold limit.
Scale Value
Set the scale based on total press capacity divided by number of channels. For example, when using a fourchannel sensor system on a 500-ton maximum capacity press, set the scale to 125.

SIGNATURE (WAVE) DISPLAY SCREEN
The wave (also called signature) screen (Figure B5) is reached by touching the tonnage meters in the
monitor screen.
The waves display the force
(tons) versus the position of the
press (usually in degrees) per
channel. Variations of force per
angle with each press stroke give
an indication of problems in the
part making process.
Pressing the “Total” meter in the
monitor screen allows the
operator to view all four
channels (two channels in two
channel system) of waves.
Pressing any of the “Channel”
meters in the monitor screen, or
pressing the wave in the four
channel wave screen, displays
the corresponding wave in a
single wave format (Figure B5).
This allows the operator to view a
particular wave in a higher resolution.
