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), "
Sens 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 soldering iron 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 the nozzle is inserted incorrectly, an incompatible
nozzle is inserted, or a foreign object has found its 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.
