OPERATING INSTRUCTIONS TREND SERIES
TREND DISPLAY-QUALITY WINDOW
Each vertical TREND column represents one channel of monitoring. The TREND portion of the instrument
works on the “benchmark” principle. The instrument will take a sample of the forming loads at each channel
and automatically establish the high and low alarm limits.
After the load sampling and the alarm setting sequence is complete, only the center green GOOD lights will
be on in each TREND display. As each subsequent part is formed, the load deviation from the ideal
condition is displayed on the TREND display.
•
The center green GOOD light of each column represents the average benchmark level. When only the
GOOD lights are on, the last part was formed at the same load as the sampled benchmark (no deviation
in load).
•
The top red lights of each column represents the HIGH alarm trip point as set by the tolerance selector
switch. A red light indicates that the last part was formed at a force higher than the setting of the HIGH
tolerance.
•
The bottom red lights of each column represent the LOW alarm trip point as set by the tolerance selector
switch. A button red light indicates that the last part was formed at a force lower than the setting of the
LOW tolerance selector.
The green lights above and below the center and any yellow lights represent caution. They indicate that the
last part was formed at a force level that was higher or lower than the optimum, but was still within the pre-
selected tolerance bands. These lights indicate that something has changed in the forming process.
