16

Operation

IMPORT ANT

P ACE recommends that you not read the “Set-Up Mode” section until after you feel
comfortable with system operation. Please read the following “Operation" section
thoroughly before changing the system settings.

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 T emperature Setback.

NORMAL OPERA TION - Normal operating mode of the system in which the
Operating Tip Temperature is displayed.

OPERA TING TIP TEMPERA TURE - 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 DISPLA Y 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.

TEMPERA TURE SETBACK - System feature which, when enabled, will
independently set back the Set Tip T emperature 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 TEMPERA TURE 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.

17

Operation

NOTE

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 115 system, when activated, will prevent
unauthorized alteration of stored system temperature parameters and feature settings
(refer to T able 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.

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.

Auto Tip Temperature Compensation

Differences between the temperature settings and true tip temperatures are negligible
when using Thru-Hole, single point desoldering tips. With any heating system
however, T rue Tip Temperatures can dif fer greatly from temperature settings when
using larger SMT soldering tips. This dif ference is called T ip Temperature Offset.
The ST 115 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 (P ACE
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.

18
