TROUBLESHOOTING | RJG, INC. SENSOR PRECHECK
32
DRIFT FAILURE
1.
Multi-channel
Something happened to cause a change in reading
during the test. Be aware that moving the piezoelectric
sensor cable during the test can cause false readings.
Check the sensor again without moving any of the
components.
•
If the test fails a second time, start testing backwards
from the mold to the electronics until drift passes.
Disconnect sensor head from 1645 cable and Retest.
•
If the test passes the problem is in the sensor head.
Disconnect 1645 cable from PZ plate and Retest.
•
If the test passes the problem is in the 1645 cable.
Disconnect PZ Plate and Retest.
•
If the test passes the problem is in the PZ Plate.
Disconnect piezoelectric sensor adapter cable (C‑PZ/
LX… ) and Retest
•
If the test passes the problem is in the piezoelectric
sensor adapter cable (C‑PZ/LX…)
•
If the test fails, the problem is in the piezoelectric
sensor adapter electronics (PZ/LX…)
Clean the sensor can cable connection points with
an approved cleaner. Follow instructions at: https://
rjginc.com/paperclip/product_downloads/547/cleaning‑
connectors_cables.pdf. Retest after cleaning.
•
If the test fails after cleaning, request an RMA from
RJG.
2.
Single Channel
Something happened to cause a change in reading
during the test. Be aware that moving the piezoelectric
sensor cable during the test can cause false readings.
Check the sensor again without moving any of the
components.
•
If the test fails a second time, start testing backwards
from the mold to the electronics until drift passes.
Disconnect sensor head from 1645 cable
•
If the test passes the problem is in the sensor head.
Disconnect 1645 cable from the piezoelectric sensor
adapter (PZ/LX1‑M) and Retest.
•
If the test passes the problem is in piezoelectric sensor
adapter.
Disconnect 1661 cable from piezoelectric sensor adapter
(PZ/LX‑S) and Retest.
•
If the test passes the problem is in the piezoelectric
sensor adapter.
Clean the sensor can cable connection points with
an approved cleaner. Follow instructions at: https://
rjginc.com/paperclip/product_downloads/547/cleaning‑
