Set temperature
Low-temperature alarm tolerance
Low-temperature alarm tolerance
EXAMPLE:
Assume that the temperature setting is 400℃/750℉ and the
tolerance 50℃/100℉. If the temperature continues to decrease
and finally falls below the value indicated while the heating
element is on, "Low Temp Error" is displayed.
When there is the possibility that a failure has occurred in the
sensor or heater (including the sensor circuit), "
Sensor Error" is
displayed and the power is shut down.
"Grip Error
" will be displayed if the connector cord is not attached
to the station OR the wrong handpiece is connected.
If the sensor temperature falls below the difference between the
current temperature setting and the low-temperature alarm
tolerance, "Low Temp Error
" is displayed and the warning buzzer
sounds. When the nozzle temperature rises to a value within the
set tolerance, the buzzer will stop sounding.
"Heater Short Error
" will flash, and the buzzer will sound
continuously, when an incompatible heater circuit is inserted, or if a
foreign object has found it's way into the connector.
This is displayed when the system is unable to operate normally.
Should this error be displayed, please contact your HAKKO
representative.

CHECK
: Is the tip coated with black oxide?
ACTION : Remove the black oxide. (Refer to “Tip Maintenance”.)
CHECK
: Is the tip or nozzle coated with black oxide?
ACTION : Remove the black oxide. (Refer to “Tip Maintenance”.)
CHECK
: Is the tip or nozzle temperature adjusted correctly?
ACTION : Perform the temperature adjustment.
CHECK
: Is the tip seized? Is the tip swollen because of deterioration?
ACTION : Replace the tip and the heating element.
CHECK
: Is the tip or nozzle temperature adjusted correctly?
ACTION : Perform the temperature adjustment.
●
Solder does not wet to the tip or
nozzle.
●
The tip or nozzle temperature is too
low.
●
The tip can not be pulled off.
(Soldering iron)
●
The tip or nozzle doesn’t hold the
desired temperature.
CHECK
: Is the heater broken?
ACTION : If the heater is broken, replace the heating element.
CHECK
: Is the setting value for the low-temperature alarm tolerance too low?
ACTION : Increase the setting value.
CHECK
: Is the cord assembly broken?
