Service and Maintenance
Software Upgrades
For information regarding software upgrades, please
contact your local authorized Smith & Nephew
representative.
Replacing/Returning Worn or Defective
Equipment or Parts
Contact Smith & Nephew Customer Service to order
replacement footswitches, extension cables, or any
other accessory, and for instructions on disinfection
and return of worn-out or defective equipment or
parts.
Other than fuses, the Smith & Nephew VULCAN™
Generator has no customer-serviceable parts. For
service, please contact your representative or Smith
& Nephew Customer Service.
Preventative Maintenance
The following inspections should be performed on an
annual basis to ensure safe operation of the Smith &
Nephew VULCAN Generator.
Inspection of Cables
Inspect the power cable and replace if signs of wear
or abrasion are visible.
Inspection of Connectors
Inspect all connectors on the control unit for signs
of wear or damage. Look specifically for bent or
damaged pins, loose fittings, etc. Contact Smith
& Nephew Customer Service for assistance if any
damage is detected.
Calibration of Temperature
Measurement Circuit
There is no method for the user to alter the
calibration of the temperature measurement
hardware in the field. However, Smith & Nephew
recommends that this calibration be checked on an
annual basis. If it is found to be out of specification,
the device should be returned to Smith & Nephew
for repair.
The generator performs a self-test during power-up
to verify power calibration. There is an internal,
100 ohm resistor which is measured and compared
to its specified value. The generator goes into a Fault
Mode if the calibration is out of specification. In
addition, the thermocouple amplifying circuits are
checked for calibration. However, there is no check
on the “absolute” temperature measured by a
temperature probe; therefore, this calibration must
be manually checked.
Equipment
• Thermometer
• TAC™-S Probe with connecting cable
• Beaker
Procedure
1. Fill the beaker with cool water (10–30° C).
2. Use the thermometer to measure and record the
temperature of the cool water.
3. Turn on the control unit and connect the cable of
the test TAC-S Probe. Verify that the control unit
goes into the Temperature Control Mode. The
TEMPERATURE should display room temperature.
4. Immerse the tip of the TAC-S Probe in the water
and record the actual temperature.
5. Repeat steps 1–4 using hot water (50–90° C).
The TEMPERATURE reading with the TAC-S Probe
should be +/- 3° C of the thermometer reading in
both cases.
If a greater difference is observed, contact Smith &
Nephew for assistance.
