SERVICE HINTS
1. OPERATIONAL PROBLEMS: Refer to the PACE Operation & Maintenance Manual (P/N 5050-
0313) for complete operational instructions on use of this product. If a Password has been installed by
the system user, remove the Password before proceeding with the repair. The user can reinstall the
Password after the system is repaired.
2. VACUUM FAILURES: Failures of this nature can be caused by either the unit or the SensaTemp
handpiece. Remove the Air Hose (and attached VisiFilter) from the SNAP-VAC Port and check for
vacuum at the port. If sufficient vacuum is present, the malfunction exists in the handpiece. Further,
if vacuum is sufficient at the port, check the vacuum level at the end of the glass solder collection
chamber (Sodr-X-Tractor handpieces only, chamber must be checked cold). Take the applicable steps
shown following.
a) Handpiece Failures: Replace VisiFilter if necessary; clean heater bore and replace tip, check air
hose for holes and ensure that glass solder collection chamber (Sodr-X-Tractor handpieces only) is
properly seated against heater seal.
b) Unit Failures: Remove the unit front panel (see "Disassembly/Assembly"). Check internal hosing
for kinks and replace internal VisiFilter (attached to pressure port on motor pump assembly).
3. HEATING CONTROL CIRCUITS: Must be checked under load (with handpiece/s plugged in). The
output(s) are obtained by switching triacs on and off. The voltage level to the handpiece(s) does not
change when adjusting the Set Tip Temperature. The control circuit of the unit varies the duty cycle of
voltage application as required to achieve and maintain the set temperature of the handpiece.
4. HEATING FAILURES: Usually caused by defective SensaTemp handpiece heaters. Refer to the
"Heater Assembly Checkout Procedures", Table I. When checking the system power source, use a
known good handpiece.

CALIBRATION
All PACE SensaTemp controllers can be checked for calibration without the need to adjust any internal controls.
If there is a requirement to check the actual tip temperature of a SensaTemp handpiece, perform the following
procedure for attaching a thermocouple wire to the handpiece tip. A Process Monitor is available from PACE
which will provide a temperature readout and can perform a variety of additional tests such as Tip to Ground
resistance and vacuum checks.
A thermocouple may be attached to a tip by spot welding a thermocouple wire onto the end of the tip or by
embedding the wire into a drilled hole at the tip end. Either method will produce accurate results. Tips (for
PACE equipment) with embedded K type thermocouples are available from PACE.
Pulse Heat handpieces are not closed loop temperature controlled and require no calibration.
MATERIALS REQUIRED
1. PACE Process Monitor or Temperature Meter.
2. Soldering Iron Tip. Listed below are the available tips PACE uses (with and without embedded
thermocouples).
a) Use PACE part number 7021-0004-P1 tip with embedded thermocouple or tip only part
number 1121-0337 on handpieces with 4.76 mm (3/16 inch) heater bore.
b) Use PACE part number 7021-0003-P1 tip with embedded thermocouple or tip only part
number 1121-0130 on handpieces with 3.18 mm (1/8 inch) heater bore.
NOTE
When using tips with embedded K type thermocouples supplied by PACE
with a K type Temperature Meter, a PACE part number 1332-0164-P1
RCA to Omega-style, K-type, thermocouple adapter must be used.
The following items are needed if you are NOT using the PACE part number 7021-0003-P1 or 7021-0004-P1
embedded tips.
3. Thermocouple, 30 AWG ("K" type when using Process Monitor or type compatible with Temperature
Meter).
4. Copper Wedge (used when embedding thermocouple) or 16 AWG Bare Copper Wire (1.22 mm
(.048 inch) O.D.).
5. Drill Bit (used when embedding thermocouple), 1.5 mm (.059 inch) diameter.
SPOTWELDING PROCEDURE
1. Place the thermocouple end onto the tip just past the tinned end (approximately 6.35 mm (.25 inch)).
2. Spotweld the thermocouple to the tip. Check to insure that the thermocouple is properly attached to
the tip.
30
REPAIR
EMBEDDING PROCEDURE
1. Drill a 1.5 mm (.059 inch) hole just past the tinned end of the soldering tip (approximately 6.35 mm
(.25 inch) when using one of the recommended PACE tips). Drill to a depth of 2.54 mm (.100 inch).
2. Place the end of the thermocouple wire into the hole. Ensure that the end of the wire bottoms out in
the hole.
3. Wedge the thermocouple into place using the copper wedge or bare copper wire. The thermocouple
should be wedged as air tight as possible.
Figure 11. Thermocouple Attachment
TIP TEMPERATURE TEST
1. Install the tip into the handpiece to be tested with the end of the tip properly seated. The
recommended PACE tips are shown extending out of the heater 9.5mm (3/8 inch).
2. Connect the free end of the thermocouple wire to the PACE Process Monitor (or temperature meter).
3. Apply power to the handpiece and allow temperature to stabilize.
