16 Memory - user data Error in the saved user data. Factory
settings are used. If CRC is correct
after switching off and on again, no
further errors are shown
Acknowledge error; system uses the
default values
17 Memory - device con-
figuration
Incorrect data in the configuration
block
Acknowledge error; system uses the
default values
(configuration = standard)
Perform software update using the
corresponding configuration
18 Memory - application Incorrect data in the application block Perform software update
19 Ambient temperature Ambient temperature too low or too
high
Ambient temperature too low or too
high; temperature sensor faulty
20 Load too highly resis-
tive (quiver detection)
Frequency monitoring ensures that
the device components do not over-
heat (not covered by temperature
sensors)
Improper use of the device; check
load and unplug welding power lead
21 FPGA communication
timeout
FPGA reports a timeout in the com-
munication to μC. FPGA deactivates
bridge
Perform software update
22 =
FUS
Mains fuse protection
power limit
Too high output power for the set
mains fuse protection in the FUS set-
up. The device shows "FUS" on the
display. The error is logged as Error
E22 in the service tool
Check mains power supply; check
FUSE setting; reduce welding current

43 Init Error in initialisation cycle Perform software update
44 Init Failed Current measurement from PFC or
PFC inductor faulty
On TP180 only:
replace LC1800 and power module
