NOTE:
Read the “Programming Your System” sections of this manual to utilize the full
capabilities of the system.
LED Display, Normal Operation
The LED Display provides a 3-digit display of temperature information. The LED Display will show:
1. A display of "888" on initial power up to ensure that all LEDs on the display are
working.
2. A display of the software version of the installed microprocessor (e.g., "1-2") for 1
second on initial power up after the "888" is displayed.
3. Actual tip temperature of the connected handpiece during normal operation. The tip
temperature displayed will flash when the system is in Temperature Setback.
4. The displayed temperature will decrease and stabilize at 177°C (350°F) when the
system is in Temperature Setback.
5. "OFF" when the Set Tip Temperature has been set to Off (below minimum set tip
temperature). Refer to the "Programming Your System" portion of this manual.
6. "OFF" plus the LED Display will be flashing when the unit has entered Auto Off.
Refer to the "Programming Your System" section of this manual.
7. Error messages ("OSE" or “CEE”) if a system fault is detected. Refer to the
"Corrective Maintenance" portion of this manual.
LED Display, Temperature Adjust Mode
The LED Display will show the following when adjusting the desired Set Tip Temperature.
1. The Set Tip Temperature.
2. "HiL" (High Temperature Limit) when adjusting the set tip temperature and the
maximum allowable temperature is exceeded. Refer to the "Programming Your
System" portion of this manual.
3. "OFF" (Low Temperature Limit) when adjusting the set tip temperature and the
minimum allowable temperature is exceeded. Refer to the "Programming Your
System" section of this manual.
3. "EP" will be displayed if a Set Tip Temperature adjustment is attempted and a
Password has been stored in system memory. As the Password is entered, the
display will change to the Set Tip Temperature if the entered Password matches the
stored Password.
5. "no" will be displayed if the entered password does not match the stored Password.
Temperature Setback Mode
To preserve tip life and save energy, the TW 100 system can be programmed to automatically set back its
Tip Temperature to 177°C (350°F) after a selected period of handpiece inactivity. The LED Display will
blink “177” or “350” depending on the selected temperature scale. As received from the factory, this
feature is enabled. Refer to the “Programming Your System” section of this manual to disable or adjust
the time-out period of this feature. The operator can also force the system into Temperature Setback.
Activating Temperature Setback:
There are two ways to activate the Temperature Setback feature.
1. AUTOMATIC ACTIVATION: The system can be programmed so that this feature will
automatically activate after a pre-selected period (10-90 minutes) of handpiece inactivity.
See the “Programming Your System” section for details on programming this feature.
2. MANUAL ACTIVATION: The operator can manually force the system into Temperature
Setback by performing the following procedure.
a. Press and hold the Scroll Down (
▼
