AcaUTION:
Do not damage or remove the Tip ID bar code sticker.
Soldering tips have different thermal chara-
cteristics, depending upon their mass, shape,
and surface area. It should be obvious that the
tip temperature at idle will not be the same for a
fine tip as it will be for a heavy chisel tip, although
the set temperature may be the same for each
tip. The FM-202 processor incorporates the ability
to electronically compensate for tip geometry
variations using Tip IDs. Each FM-202 tip style
has a specific Tip ID; whenever a tip is changed,
the Tip ID should be entered into the FM-202 for
most effective process control.
There are two ways to enter Tip ID data into the
FM-202:
See below or page 6 of this manual. This proce¬
dure is the simplest and most common.
See Appendix A of this manual, when the Tip ID is
not readable for some reason.
How to read out the bar code of
the tip into the FM-202:
1. Insert the tip (connector side) into the pro¬
cess gate in the front of the station.
2. Insert the tip until the buzzer sound once.
The display shows l5-f I The LED indi-
cator will stop flashing. Now the tip identi-
fication number has been stored.
NOTE:
When the buzzer sounds three times is reading error, insert
the tip again. _ _
/jV^CAUTION:
Do not insert the tip opposite side or other incompatible tip.
ACAUTION:
When tip is inserting the FM-2027, the process gate cannot
read the bar code. If a tip insert into the process gate while
the tip is already in the FM-2027, buzzer will sound irregular-
ity. Remove the tip from the FM-2027 for reading the Tip ID.

8. PARAMETER SETTINGS
• Entering the parameters
(1) °C or °F temperature display
(2) Auto power shutoff
This is an optional setting. When it is
activated and the soldering iron is not used
for 30 minutes, the power to the heating
element is shutoff automatically and the
buzzer will sound three times. When the
temperature decreases to 100°C/200°F the
display will show — . To resume solder¬
ing, cycle the power switch OFF, then ON.
The power will be turned on automatically
if you hit any button before the temperature
decreases to 100°C/200°F.
To bypass this procedure and continue to
resetting the low temperature alarm toler¬
ance setting press the ^ button once.
The FM-202 has the following four parameters:
1) “C or °F temperature display selection
2) Auto power shutoff
3) Low-temperature alarm tolerance setting
4) Supervisor or operator control setting
Once the station enters parameter mode, set the
parameters in the order shown below. Once all
the parameters have been set, normal operation
will be resumed.
1. Turn power OFF.
2. Insert the control card into the card slot in the
front of the unit.

(3) Resetting the low temperature
alarm tolerance setting
This unique function alerts the operator when
the sensed temperature drops below a set li mit.
Should this occur, an error message |H-^| will
be displayed, and the buzzer will sound con-
tinuously. When the temperature returns within
the allowable range, the buzzer will stop. The
value is stored in the FM-202 as described be-
low;
EXAMPLE:
If the set temperature is 650°F and the low temperature
alarm is 100°F, the alarm will trip when the sensed tem¬
perature goes below 550°F. _____
NOTE:
The threshold limits are: 30 -150°C; 60 - 300®F.
If a value outside these limits should be entered. the sys¬
tem will revert to the beginning of the mode. the hundreds
digit will flash, and the procedure must be restarted.
1. When the station enters low-temperature
alarm tolerance setting mode, the hundreds
digit begun flashing. Enter and store the
value in the same manner as described on
page 7 “Changing the temperature setting.”
2. If you enter a value exceeding the allowable
range shown to the left, you will be brought
back to entering a value in the hundreds
digit. If this occurs, reenter a correct value.
3. Once the value is stored, the system will
automatically sequence to the resetting the
supervisor or operator control setting.

3. Atter use
4. When the unit is not being used
and the auto power shutoff is not
active.
5. inspecting and cieaning the tip
High temperatures shorten tip life and may
cause thermal shock to components. AIways
use the lowest possible temperature when sol¬
dering. The excellent thermal recovery charac-
teristics of the FM-202 ensure effective solder¬
ing at low temperatures.
AIways clean the soldering tip before use, to
remove any residual solder or flux adhering
to it. Use the 599B tip cleaner (provided with
the FM-202) or use a clean and moist clean¬
ing sponge (part no.A1519). Contaminants on
the tip have many deleterious effects, inciuding
reduced heat conductivity, which contribute to
poor soldering performance.
AIways clean the tip and coat it with fresh sol¬
der after use. This guards against oxidation.
Never allow the unit to idle at a high temperature
for extended periods. This will allow the tip to
become oxidized. Turn the power switch OFR
If it is to be out of service for several hours, it is
advisable to pull the power plug as well.
This procedure, if followed daily, will materially
add to tip life.
a. Set the temperature to 250°C (482'’F).
b. When the temperature stabilizes, clean the
tip (see 2, above) and check the condition of
the tip. If the tip is badly worn or deformed,
replace it.
c. If the solder plated part of the tip is covered
with black oxide, apply fresh solder, con-
taining flux, and clean the tip again. Repeat
until all the oxide is removed, then coat the
tip with fresh solder.
/(J^CAUTION:
NEVER file the tip to remove oxidesl __
d. Turn the power OFF and remove the tip, us-
ing the heat resistant pad. Set the tip aside
to cool.
e. Remaining oxides, such as the yellow dis-
coloration on the tip shaft, can be removed
with isopropyl alcohol.
