Set-Up/Operation

Handpiece Heater Burn In

T oeinsure optimum performance and long life, some new handpieces must undergo a
burn in procedure. A Red tag is attached to the handpiece and with replacement heater
assemblies. Follow the Burn In procedure listed on the tag when setting up a new ST 65
system or when replacing a handpiece heater assembly .

NOTE

Ensure that the system is placed in a well-ventilated area. Smoke will be emitted from the
heater assembly during the burn in cycle.

Temperature/Dial Lock

The Variable T emperature Control Knob can be locked in
position to avoid accidental or unauthorized changes of
the temperature setting. Perform the following procedure
to lock the Variable T emperature Control Knob.

1. Adjust the Temp. Control Knob to the desired
temperature setting.

2 . Using the Temp. Locking Key (hex key supplied

with system), tighten the set screw on the Temp.
Locking Ring closest to the front panel.

Temperature Selection

Variable Temperature Control

Adjust the Variable T emperature Control Knob to the
desired temperature setting. Notice that the control dial
has a White graphic scale denoting temperature in °C
(Celsius) and a Yellow graphic scale denoting
temperature in °F (Fahrenheit). These numerical scales
denote the set tip temperature times 100 (e.g., “3” on the
White scale is 3 x 100 or 300°C).

17

Operation

Tip Offset

Differences between the temperature settings and true tip temperatures are negligible
when using Thru-Hole, single point soldering tips. With any heating system however,
True T ip Temperatures can differ greatly from temperature settings when using larger
SMT soldering tips. This difference is called T ip T emperature Of fset. P ACE
recommends the use of the T ip & T emperature 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.

LED Full On - Continuous power is being delivered to the handpiece. This condition is
evident when the system is first powered up (handpiece heater cold) or the Variable
T emperature Control setting is increased.

LED Flashing - Indicates that the set tip temperature (as set on the Variable Temperature
Control) has been reached. Power to the handpiece is cycling Off and On to maintain set
temperature.

LED Off - No power is being delivered to the handpiece heater. This condition is evident
for a short period of time when set temperature is reached and stabilizing or if the Variable
T emperature Control setting is decreased. If the LED never illuminates, check for a faulty
handpiece (see Corrective Maintenance section). Also, if no handpiece is connected to
the power source, the LED will not illuminate.

LED Operation

The Green colored LED on the power source front panel indicates System Status and
Power Receptacle output status (LED OFF , ON or Flashing). Following is an explanation
of these status indicators.

18

Calibration

The ST 65 system is tested for temperature accuracy at the factory and can be
checked for calibration according to P ACE requirements. Also, a temperature setting
normally used by the operator can be adjusted to the precise temperature indicated
on the Dial/Display . No internal adjustments can be made to the power supply. To
verify calibration of the power supply , perform the following procedure.

1. Install a tip with an attached thermocouple
wire into the handpiece connected to the
system. Tips with K type thermocouples
are available from P ACE; use part number
7021-0004-P1 when ordering.

2. Connect the thermocouple assembly to a PACE Process Monitor (part
number 8001-0077 or 8001-0078) or appropriate temperature meter.

3. When set fully counterclockwise,the pointer of the Variable Temperature
Control knob will align to the Calibration Mark as shown. W ith the
system turned on, adjust the Variable Temperature Control to obtain a
stable tip temperature of 300°C (for P ACE factory specifications) or the
temperature setting normally used by the operator .

If the temperature displayed on the Process Monitor (or temperature meter) is
within ±15°C (27°F), perform steps 4 thru 6 to obtain a precise reading. If the
temperature is off by more than ±15°C, the handpiece may require
maintenance. Recheck the temperature using a second handpiece.

4 . Carefully lock the Variable T emperature Control in position by tightening

the inner set screw (closest to front panel).

5. Loosen the outer set screw on the Variable
T emperature Control knob (furtherest from
front panel) using the T emp. Locking Key (hex
key) supplied with the system. Position the
knob with the pointer aligned to match the
temperature indicated on the Process Monitor
(or temperature meter). Secure the knob in
position by tightening the outer set screw.

6. Loosen the inner set screw to unlock the
V ariable Temperature control if adjustment of
operating tip temperature is desired.
