Isolating TRIND from CRIND
To isolate the TRIND system from CRIND, proceed as follows:
1
Shut off all power to unit.
2
Disconnect either Side A or B Light Micro Reader Cable (R20519-G3) from either J8
(Side B) or J7 (Side A) on the DCB in the TRIND Card Cage, and insert the standalone jumper
in-line (between J8 and P8 or between J7 and P7). For jumper details, refer to
Jumper Cable (R20602-G1) for LF/UHF Full System”
Note: If Standalone Jumper Cable (R20602-G1) or 9 V alkaline battery is not available, unit
can be put in standalone mode by installing jump jack on JP3 on Light/Micro Reader
Board (for information on Isolating TRIND from CRIND, refer to
PCB (T20446-G1, T20601-GX, M01580A001, and M01580A002)”
).
Perform for Side A only for the Card Cage Assembly.
3
Remove J4 from DCB.
4
Restore power to unit, and test TRIND operation (for information on test TRIND operation,
refer to
“Dummy Load Transmitter (R20526)”
. If TRIND functions properly the
problem is with CRIND or CRIND related equipment, refer to
MDE-2562 CRIND Service
Manual
.
Tag Testing
Perform the following procedures to begin TRIND tag testing. To test the full controller drive
capability, do not place TRIND in the standalone mode. Allow the dispenser network to detect
the other subsystems (pump, CRIND, TRIND, etc.). The standalone procedure will verify that
TRIND hardware is good (or not). The standalone procedure isolates TRIND from CRIND.
Car Mounted Test Tags
1
Place the unit into the standalone mode. For the appropriate standalone cable connection, refer
to
“Standalone Jumper Cable (R20602-G1) for LF/UHF Full System”
on
.
2
From Side A of the unit, hold the Car Mount Test Tag, from the ASC TRIND Tool Kit in front
of the unit at a distance of approximately 6 inches from the face of unit. Observe that the door
or faceplate TRIND indicator lights.
3
Repeat steps
and
for Side B.
