PERMAGROUND Tip in the heater.
3. If proper Tip orientation is required, the setscrew can be tightened to hold the tip in place.
Also, heat transfer will improve when the setscrew is used.
Installing Non-PERMAGROUND Tips
1.
Insert the Tip fully into heater bore using the supplied Tip Tool.
2.
Gently tighten the heater Set Screw.
3.
Recheck the tip Set Screw periodically to insure that it remains snug.
NOTE:
Periodically, clean the heater bore with a properly sized wire brush
(3/16" O.D. to insure optimum heat transfer and proper tip grounding when
non-PERMAGROUND tips are used.
Definitions
Please read and become familiar with the definitions of each of the following terms that are used
repeatedly in the following operational procedures.
Auto-Off:
Safety feature that turns power off (10-90 minutes, settable in 10 minute increments)
after the system has entered Temperature Setback.
Normal Operation:
Normal operating mode of the system in which the Operating Tip
Temperature is displayed.
Set Tip Temperature:
The operator selected idle tip temperature entered into the system
memory.
Set-Up Mode:
Mode of operation in which the operator can quickly and easily adjust the system
parameters (e.g., temperature limits, password, setback time).
Temperature Adjust Mode:
Mode of operation where the Set Tip Temperature may be
adjusted.
Temperature Display Impedance (TDI) Mode:
Stabilizes the tip temperature shown on the LED
Display by ignoring minor temperature fluctuations. Displayed changes in temperature are
delayed (impeded) for two seconds when a load is applied to the tip. Two seconds after the load
is removed, the displayed temperature will begin rising to set temperature. Particularly useful in a
production environment for monitoring of set temperatures, since under most production
circumstances the temperature will not deviate.
Temperature Setback:
System feature that will independently set back the Set Tip Temperature
to 177°C (350°F) after a user selected period of handpiece inactivity (10 to 90 minutes, settable in
10 minute increments). This feature is enabled (or disabled) in the Set-Up Mode.
Tip Offset Constant:
Specific value for a given handpiece/tip combination upon which the
system automatically calculates the correct Tip Temperature Offset at any entered Set Tip
Temperature. This value is the temperature loss (Tip Temperature Offset) at 371°C (700°F) and
is set in the Set-Up Mode. A value of 0-115°C (0-240°F) may be entered in the Set-Up Mode.
Password:
The Password feature of the ST 45 or ST 55 system will prevent unauthorized
alteration of stored system temperature parameters and feature settings (refer to Table I, “Factory
Settings”). If a Password has been installed, the LED Display will display an instruction to enter
the Password (a 5 key sequence of the keys on the system front panel) when a setting change is
attempted.
