Note
: The clip detector is to be mounted 3 to 4 inches away from the
first idler toward the tail pulley and the coil support structure. If it is not
mounted according to the installation placement drawings, the clip
detector may intermittently miss clips.
1. If the clip detector is out of detection range, readjust the clip
detector. (Refer to the appropriate Installation Placement drawing
for your system.)
2. If the clip is too small, add an additional clip on the side of the belt.
Mark the section of the belt where the false trip occurs and inspect
this section of the belt when it is stopped.
If the clip detector is functional and is detecting all the clips, CLIP
shows on the display, and the TMD is false tripping on the clips, the
problem is too high a clip sensitivity.
Follow this procedure to adjust the clip sensitivity.
1. Scroll to the CLP CORS display and record the clip coarse
sensitivity value shown in the counter.
2. Scroll to the CLP FINE display and record the clip fine sensitivity
value shown in the counter.
3. Perform an auto-calibration for both coarse and fine clip sensitivity
as described in Section “Initial Setup Procedure”.
4. Scroll to the displays and record the new CLP CORS and CLP FINE
values.
5. Compare the old and new CLP CORS values.
If they are not the same, the clip sensitivity has been changed by the
auto-calibration. Go on to Step 6.
If they are the same, go to Step 8.
6. Run the conveyor and check for false trip from clips. Observe the
LED bar graph.
When the largest clip on the belt passes, 10 to 12 LEDs will light.
7. If the TMD does not false trip and the bar graph shows 10 to 12
LEDs on the largest clip, the old CLP CORS value was incorrect; the
new value should be used.
