8. CHECKING PROCEDURE
WARNING
Unless otherwise directed, carry out these procedures with the power switch OFF and the power UNPLUGGED.
■Check for a broken heater or
1. Check for a broken heater or sensor
sensor
Measure the resistance across this position.
Verify the electrical integrity of the heater and sensor.
Measure the resistance of the heater and sensor while at room
temperature（15∼25℃；59∼77℉）. It should be 8 Ω ±10%. If
the resistance exceeds these limits, replace the tip.
■Check the grounding line
1. Unplug the connection cord from the station.
2. Measure the resistance value between Pin 2 and the tip.

If any value exceeds 0 Ω or is ∞, replace the HAKKO FM-2027.
1. Unplug the power cord from the power receptacle.
■Replacing the fuse
2. Remove the fuse holder.
3. Replace the fuse.
4. Put the fuse holder back in place.
9. TROUBLE SHOOTING GUIDE
WARNING
Before checking the inside of the HAKKO FM-206 or replacing parts, be sure to disconnect the power
plug. Failure to do so may result in electric shock.
● The unit does not operate

CHECK
: Is the fuse blown?
ACTION : Replace the fuse. If the fuse blows again, send the unit in for repair.
● The tip does not heat up.
CHECK
: Is the tip inserted properly?
"Sens Error" is displayed.
ACTION : Insert the tip completely.
CHECK
: Is the connection cord and/or the heater/sensor broken?

If the "Zero-Cross Error" / "System Error" continues to be displayed after
turning on the power switch, contact your HAKKO representative.
10. ERROR MESSAGE
● Sens Error
When there is the possibility that a failure has occurred in the
sensor or heater (including the sensor circuit), "Sens Error" is
displayed and the power is shut down.
● Grip Error
"Grip Error" will be displayed if the connector cord is not attached
to the station OR the wrong soldering iron is connected.
● Low Temp
If the sensor temperature falls below the difference between the
current temperature setting and the low-temperature alarm
tolerance, "Low Temp" is displayed and the warning buzzer sounds.
When the tip temperature rises to a value within the set tolerance,
EXAMPLE:
the buzzer will stop sounding.
350℃ (400℃ - 50℃)
EXAMPLE:
Set temperature
Assume that the temperature setting is 400℃/750℉ and the
Low-temperature alarm tolerance
tolerance 50℃/100℉. If the temperature continues to decrease
OR
and finally falls below the value indicated below while the heating
650℉ (750℉ - 100℉)
element is on, the displayed value starts blinking to indicate that

the tip temperature has dropped.
Low-temperature alarm tolerance
● Heater Short Error
"Heater Short Error" will flash, and the buzzer will sound
continuously, when the tip is inserted incorrectly, an incompatible tip
is inserted, or a foreign object has found its way into the connector.
● Heat up Error
This is displayed in cases such as when the iron tip abnormally
(For MODEL FM-2023)
heats up relative to the set temperature when the micro-tweezers
(MODEL FM-2023) are connected.
● Drive Error
This is displayed in cases such as when judged that an excessive
(For MODEL FM-2023)
pulse has been generated when the micro-tweezers (MODEL
FM-2023) are connected.
● TRig Error
A "trig error" will occur if the trigger is pulled before the nozzle
temperature has reached the set temperature. Please wait until the
temperature reaches the set temperature and stabilizes.
● Zero-Cross Error
This is displayed when a zero-cross cannot be measured in the
designated cycle. Should this error be displayed, please contact
your HAKKO representative.
● System Error
This is displayed when the system is unable to operate normally.
Should this error be displayed, please contact your HAKKO
representative.
● Det Error
"Det Error" appears on the display when turning the power on after
connecting the MODEL FM-2022/2023 with a hot tip.
This is not an error.
Wait for approximately 10 seconds until the model functions
properly.
