WaveRIDER 151
6.1.1 RIDER Troubleshooting Steps
Decide if the problem is with the Super M.O.L.E. Gold Hardware, communications or
Software.
If the problem occurs while attempting to log data, the Hardware may be faulty.
If the problem occurs while attempting to communicate between SuperM.O.L.E.
Gold and the PC, the Communications links may be faulty.
If the problem occurs while attempting to use some other function of the
WaveRIDER Software, the software may be faulty.
Incorrect or Inappropriate Readings:
Time, Speed or Contact Length measurements are dependent on good sensor contact
with the solder wave. The most frequent causes of poor solder wave contact are:
1) Extremely turbulent solder wave.
Solder wave splash causes the wave to "miss" the sensor.
2) Extremely shallow or low solder wave.
The solder wave may be too low to reach the contacts.
The solder wave may be in contact less then 0.1 sec.
Raise wave, or lower RIDER.
3) Lack of solder flux.
Although not required, some flux does aid in duplicating the same conditions
your product sees.
4) Too much flux or flux build-up over time.
Flux may insulate the sensor from the solder wave.
Clean the Pallet or sensor contacts (See section 3.5 Storing the RIDER).
5) Contact corrosion.
The flux may be too active and is corroding the contact material
6) Active acid fluxer can cause incorrect contact detection.
Start the RIDER after flux has been applied or run without flux
7) Fast conveyor speed readings can be caused by oven T/C’s on the conveyor.
Replace coupon if suspected.
Temperature readings are taken from the three coupon sensors. Shorted or open T/Cs
are the most common cause of errors. A shorted T/C will read near room temp or
respond very slow relative to the other sensors. An open T/C will cause a sudden rise in
the temperature graph printout and often ###F or C values on the tables.
