refer to “Adjusting for Bar/Rod Detection” and “Passing Bars or Rods
Undetected”.
This screen is used to set the maximum length of the bar or rod for the
TMD to detect. The display shows BAR LEN. The counter shows the
length in feet from 1.0 to 50.0.
This screen has two functions depending on the device configuration. A
DIP Switch setting on the display board specifies whether a speed sensor
is used (refer to Section “DIP Switch Settings”).
If speed sensor input is disabled, this screen is used to set the belt speed
in feet/minute. If speed sensor input is enabled, this screen shows the
actual belt speed. The display shows BELT SPD. The counter shows
the value from 1 to 1,200 feet/minute.
If the belt speed is greater than 999 feet/minute, it will be shown in
thousand feet/minute with a decimal point and an “H” following the
number. For example, 1.1H is 1,100 feet/minute.
This screen is used to set the delay after detection for the timed marking
output. The display shows TIME DLY. The counter shows the timed
delay in seconds from 0.1 to 9.9. The timed output has a queue of 10.
This screen is used to set the duration of the timed marking output. The
display shows TIMED DUR. The counter shows the timed duration in
tenths of a second from 0.1 to 0.9.
This screen is used to set the interval for running of EST. The display
shows the current interval setting.
This screen is used to set the TMD measurement window timing.
Window timing is based on a material type code from 0 to 7. The
display shows MAT CODE. The counter shows the current material
code number being used. This value is pre-set to 3.
This screen indicates the slope of the decay curve over time for the
tramp metal signal. The display shows TIME CON. The counter shows
a number representing the slope of the curve from 1 to 999. The larger
