10. ERROR MESSAGES (Soldering iron)
B. Broken Cord Assembly
There are two methods of testing the cord
assembly.
1. Turn the unit ON and set the temperature control
knob to 480℃. Then bend the iron cord at various
locations along its length, including in the strain
relief area. The cord assembly needs to be
replaced if S-E is displayed or although the LED
heater lamp flashes, the tip temperature doesn’t
rise.
2. Check the resistance between the plug pin and the
terminal lead.
Pin 1: Red Pin 2: Blue Pin 3: Green Pin 4: White
Pin 5: Black
Resistance: 0 Ω.
If it is higher than 0 Ω or is ∞, the cord should be
replaced.
CAUTION
The power lamp starts to flash when the
temperature reaches 480°C (880°F) regardless
of the condition of the cord.

EXAMPLE:
When there is the possibility that a failure has occurred in the sensor or
heater (including the sensor circuit), is displayed and the power is
shut down.
CAUTION
The sensor error also occurs if the tip is not inserted properly.
If the sensor temperature falls below the difference between the current
temperature setting and the low-temperature alarm tolerance, is
displayed and the warning buzzer sounds. When the tip temperature
rises to a value within the set tolerance, the buzzer will stop sounding.
EXAMPLE:
Assume that the temperature setting is 400°C/750°F and the
tolerance 50°C/100°F. If the temperature continues to decrease and
finally falls below the value indicated below while the heating element
is on, the displayed value starts blinking to indicate that the tip
temperature has dropped.
