•
In case the SPM is removed during output configuration, check whether the ribbon
connection from the SPM digital board to the LED PCB back side of the LID is connected
as shown below in Figure 11.
•
If after the above steps are followed, the rotor active LED is not glowing, then check for
loose wires inside the SPM or contact the factory for technical support.

4.3 SHUNT Calibration Not Operating
•
Check that the “Power LED” and “Rotor Active” light is showing green, prior to using the
SHUNT CALibration function.
•
Check that the RF cable is in good condition and is of the correct length (look for damage
to the outer sheath that may indicate that the cable has been crushed at some time).
•
Check that the caliper coupling module has been correctly positioned in close proximity to
the rotating antenna. Use the positioning alignment tool supplied with the system to
confirm the position. Move the caliper coupling module to try and achieve coupling and
SHUNT CAL functionality in an alternative position.
•
Check that there are no metal parts (flanges, covers, etc),
within 2 inches (51 mm) of
the
caliper coupling surfaces.
•
Check that the power supply is actually 12 VDC when the caliper coupling module is in the
appropriate position.
•
Make sure “scon” SHUNT CAL on command is not given in software Toolkit which will
make SHUNT CAL on always. Type “scoff” command in the Toolkit window to switch off
SHUNT CAL. Refer to the TMS Toolkit User Manual for more information.
4.4 No Communication
•
Check all wiring.
•
If using the RS232 port, check the Rx pin of the host computer is connected to the Tx pin
of the TMS 9250 and vice versa.
•
Check that the RS232 interface cable being used is of high quality or try a shorter length
of cable (RS232 is sensitive to cable length and grounding issues, especially when used
with laptop computers where grounding is uncertain).
