What should you do if you experience a fuse failure?

Fuse failures are usually caused by shorts in the handpiece. Always check each connected handpiece using the “Heater Assembly Checkout Procedures” table before replacing the fuse.

---

What should you ensure about the replacement fuse?

Ensure that the replacement fuse is the proper value for the power source. Refer to the “Power Source Replacement Parts” table.

---

What can cause vacuum failures?

Failures of this nature can be caused by either the unit or the handpiece.

---

How do you check for vacuum failures?

Remove the air hose (and attached VisiFilter) from the AUTO SNAP-VAC (or 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).

---

What are the steps to take for 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.

---

What are the steps to take for unit failures?

Remove the unit front panel (see “Disassembly/Reassembly”). Check internal hosing for kinks and replace internal VisiFilter (attached to pressure port on motor pump assembly).

---

How are heating control circuits checked?

Heating control circuits must be checked under load (with handpiece/s plugged in).

---

How is the output obtained?

Does the voltage level to the handpiece(s) change when adjusting the Variable Temperature Control knob(s)?

No, the voltage level to the handpiece(s) does not change when adjusting the Variable Temperature Control knob(s).

---

How is the temperature level achieved?

Temperature level is achieved by varying the number of “on” cycles that the voltage is applied as opposed to the number of cycles “off”.

---

How does the control circuit of the unit maintain the set temperature of the handpiece?

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.

---

What usually causes heating failures?

Heating failures are usually caused by defective handpiece heaters.

---

What is the normal operation of the channel LED?

In normal operation, the channel LED will turn hard on until the preset temperature is reached, will blink when at temperature and will be off when temperature is higher than the set temperature (when reducing set temperature).

---

What does it mean if the channel LED is always hard on or never lights?

If the channel LED is always hard on or never lights, the handpiece heater assembly is probably defective. Refer to the “Heater Assembly Checkout Procedures” table.

---

What is the procedure for replacing the VisiFilter element?

Follow the procedure listed below to replace the VisiFilter element when it becomes clogged or discolored:

1. Disconnect the handpiece air hose by gently turning and pulling the coupled Fittings.
2. Disconnect the VisiFilter and hose assembly from the Power Source by gently turning and pulling the male Fitting inserted into the AUTO SNAP-VAC Port.
3. Disconnect VisiFilter from both attached 1 inch air hoses by gently turning and pulling the VisiFilter while holding each of the hoses.
4. Separate the 2 plastic housing halves of the VisiFilter in the following manner:
   • Grasp the VisiFilter in the palm of the hand with the Male Nib (air hose connection) marked “FLOW IN” facing you.
   • Pull against one of the Wing Tabs while pulling on the Male Nib with the free hand to open the interconnection of the plastic housings at that Wing Tab.
   • Pull against the second Wing Tab while pulling on the Male Nib to open the remaining interconnection and separate the plastic housings.
5. Remove the old or discolored Element and discard.
6. Insert the replacement VisiFilter Element into the housing marked “FLOW IN”. Center the Element in the housing well.
7. Squeeze the 2 plastic housing halves together using 4 plastic Bumps on the housing marked “FLOW OUT” as pressure points. The 2 plastic housings will snap together and lock the VisiFilter Element in position.
8. Reconnect the 1 inch air hoses (removed in step 3) to the VisiFilter.

What handpieces are the “Heater Assembly Checkout Procedures” applicable to?

The following “Heater Assembly Checkout Procedures” are applicable to all PACE SensaTemp handpieces except for the TT-65 ThermoTweez & DTP-80 handpieces. Refer to applicable Operation & Maintenance Manual for troubleshooting procedures pertinent to that handpiece.

---

When should you perform the “Heater Assembly Checkout Procedures?”

Perform the “Heater Assembly Checkout Procedures” with the handpiece (and heater) at room temperature. If the handpiece is warm, resistance readings will be different from those shown.

---

What should you do if there is no heat?

Check the resistance – Pin 2 to Pin 5. If the circuit reads open, the cause is an open heater, and you should replace the heater assembly. Check the resistance – Pin 3 to Pin 6. If the circuit reads open, the cause is an open sensor, and you should replace the heater assembly.

---

What should you do if the handpiece is overheating?

Check the resistance – Pin 3 to Pin 6. If it is less than 105 ohms, the cause is a shorted sensor, and you should replace the heater assembly.

---

What should you do if the fuse blows when the unit is turned on?

Check the fuse for the proper value and type. If the fuse is incorrect, replace the fuse with the proper value and type. Check the resistance – Pin 2 to Pin 5. If the resistance is low, there is a solder short in the handpiece, remove the short and replace the heater assembly & fuse F1. If the resistance is low, there is a shorted heater and you should replace the heater assembly and fuse F1.

---

What should you do if there is no ground on the tip?

Check the resistance – Pin 4 to a tip. If the resistance is not less than 2 ohms, the cause is oxidation buildup on the tip, and you should clean the heater bore with a proper wire brush. If it is still not less than 2 ohms, replace the heater assembly.

Table 1. Heater Assembly Checkout Procedures

Symptom	Checkout Procedure	Cause	Solution
No heat	Check resistance – Pin 2 to Pin 5. Refer to “Heater Specifications.” If resistance is high -Check resistance – Pin 3 to Pin 6. If circuit reads open –	Open Heater	Replace heater assembly. Replace Heater Assembly.

If the fuse blows when a handpiece is plugged in, see Table 1 or refer to the applicable handpiece manual. Replace the fuse.

---

What should you do if there is no heat on the handpiece and other handpieces work on the power source channel?

If there is no heat on the handpiece and other handpieces work on the power source channel, a defective heater may be the cause. See Table 1 or refer to the applicable handpiece manual.

---

What should you do if there is no heat on the handpiece and other handpieces do not work on the power source channel?

If there is no heat on the handpiece and other handpieces do not work on the power source channel, a defective control circuit may be the cause. Refer to the “Troubleshooting” section Heat Output flow chart or Contact the PACE Service Department.
