How to set the trending parameters
The following parameters can be set in connection with trend monitoring (select single trend screen
first to get access to entry mode):
- "Trend monitoring" active "Yes" / "No"
When set to "Yes", the trend limits will be shown as thick solid lines.
When set to "No", the trend limits will be shown as thin dotted lines.
- "Duration" determines the length of the trend graph on the screen from left to right. Time frame
can be set between 15 minutes and 24 hours. Each channel can be set to it's individual time.
Adjusting the trend limits
The trend limits can be adjusted independently for each monitored channel. Press the Trend Limits
function key. A windows will come up on the left side of the screen giving you
access to altering the limits.
How to set the limits:
- use the cursor up or down keys to move the limit to the desired set point, and confirm by
pressing the E-key, or
- enter the new numbers with the numeric keypad, and confirm with the E-key.
The trend graph will be plotted on the screen from left to right according to the selected duration of
the graph. Machine running time in AUTO mode is plotted in green with the height of the graph
showing the trend of the average peak force reading. When the graph has reached the right end of
the screen it will jump back to about the middle of the screen and continue from there. The gaps in
between indicate that the machine is down in STOP mode, while time in MAN mode is shown in
yellow. If the average peak force goes above or below the trend limits, the machine will be stopped
(provided you have "Trend Monitoring" active for that channel).
