Error Meaning
Fault Description
or Condition
Cause
Advice
Er01
Tuning Fault
(Phase Fault)
Primary V & I out
of phase
Can't find resonant
frequency
Check resonant loop parameters and
adjust if needed - load coil inductance,
tank capacitors values, transformer taps
Er02
Current Fault
I primary > I Max
Output current exceeds
the limit
Possible FET/IGBT failure in the Power
supply. Contact our Service department
Er03
Frequency
Fault
F < F min or F > F
max
Frequency goes out of
the pre-programmed
range during Heat On
Check resonant loop values, tank
capacitors or control board. Check load
coil for shorted turns.
Er04
PS Over
Temperature
T° heat sink
>60°C
The heat sink of the
power supply exceeds
the max allowed T°
Check fans, blockages of the vents or fan
finger guards
Er05
Auto-Tune
Failed
The resonant
frequency is not
found
The unit could not find
resonant frequency
during auto sweep
Check resonant loop parameters and
adjust if needed - load coil inductance,
tank capacitors value
Er09
Communicatio
n Fault
Communication
Error Between
Panel and
Control Board
No acknowledgement is
received after the last
command
Check cables and RS connectors
between boards
Er21
High
Frequency
Fault
F > F max
The resonant frequency
of the tank circuit is
above the high limit.
Check (adjust) values of Tank Capacitors
or/and Load Coil inductance
Er28
Cooling Fault
Coil fan, Fan
Power supply or
Coil Themp. fault
Coil fan is faulty, Fan
Power Supply is faulty or
Coil temp. is over 110°C
Check 12V DC SMPS or Change the
cooling Fan
Er32
Missing phase
Main supply
dropout
Bad supply net
-
Er41
Temp Fault
T
measured >
T pT limit
High Heat station
temperature
Turn off the machine and wait until to
cool
t HI
Coil
overheating
Coil temp
exceeds
threshold value
Very long “HEAT ON”
time
Waite 5 min in “Heat OFF” and use timer
to limit “HEAT ON” time to 20min. max.
