Operation

Auto Tip Temperature Compensation and Offset

Differences between the temperature settings and true tip temperatures are negligible when using Thru-Hole, single point desoldering tips. With any heating system however, True Tip Temperatures can differ greatly from temperature settings when using larger SMT soldering tips. This difference is called Tip Temperature Offset. The ST 145 Auto Tip Temperature Compensation feature lets you set and display true tip temperatures regardless of size and type of tip or handpiece. PACE recommends the use of the Tip & Temperature Selection System booklet (PACE P/N 5050-0251) as a guide to accurately set and maintain a true tip temperature for any size and type of SMT tip. The booklet contains a listing of PACE tip information including the Tip Offset Constant (for each tip), which must be stored in system memory to ensure tip temperature accuracy. Refer to the “Set-Up Mode” section of this manual for instructions on using this feature.

As with any system, Set and Operating Tip Temperatures are only exactly equal when the handpiece is idling (unloaded at equilibrium). During use, (i.e., under load) the Operating Tip Temperature will usually be lower.

Password

The Password feature of the ST 145 system, when activated, will prevent unauthorized alteration of stored system temperature parameters and feature settings (refer to the “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. Entry of the correct Password at this point will allow the operator to proceed with the desired changes. Once the correct Password has been entered, the operator can continue to make changes to Tip Temperature settings. To reactivate the Password protection, simply turn the system Power Switch off and then back on. The system is now in normal operation. Refer to the “Set-Up Mode” section of this manual for instructions on entering, changing or removing a Password.

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 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., "1-1") for 2 seconds on initial power up after the "888" is displayed.

3. Actual tip temperature of the connected handpiece during normal operation.

4. The tip temperature displayed will flash when the system is in Temperature Setback.

Page 14

5. The displayed temperature will decrease and stabilize at 177°C (350°F) when

the system is in Temperature Setback.

6. "OFF" when the Set Tip Temperature has been set to Off (below minimum

set tip temperature). Refer to the "Set-Up Mode" portion of this manual.

7. "OFF" plus the LED Display will be flashing when the unit has entered Auto

Definitions

Please read and become familiar with the definitions of each of the following terms which are used repeatedly in the following operational procedures.

AUTO OFF - Safety feature which 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. OPERATING TIP TEMPERATURE - The true tip temperature at which the handpiece tip operates at any given time. 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 in which the operator can quickly and easily adjust the Set Tip Temperature. 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 which, when enabled, 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. TIP TEMPERATURE OFFSET - Difference in value between the temperature measured by the temperature sensor (at the heater) and the true temperature of the tip at a given Set Tip Temperature.
