Control Cable Connector Fuse; Cable Network With Over Voltage Or Under Voltage; Missing Phase In The Electric Network; Machine Error Codes - Kemppi KempGouge ARC 800 Operating Manual

4.2

COntrOl Cable COnneCtOr Fuse

The rear wall of the power source contains fuse A9, which protects the control cable connector
A7. Using an incorrect fuse may cause damage to the power source. It is important that you
always use the right kind of fuse. The type and size of the fuse are indicated next to the fuse
socket.
4.3

Cable netwOrK with Over vOltaGe Or under vOltaGe

If the power source is used in an electric network with insufficient voltage (less than 300 V),
the control features of the device are automatically disabled.
The primary circuits of the power source are protected against power spikes. The product's
mains voltage range is broad enough to prevent over-voltage problems at up to 440 V (see
Technical specifications). Make sure that the voltage remains within the allowed range,
especially if the operating power is supplied by a generator set.
4.4

missinG phase in the eleCtriC netwOrK

If a phase is missing from the mains current, the gouging features will be adversely affected or
the machine may have problems starting. Loss of a phase can be caused by a:
• Blown mains fuse.
• Damaged connection cable.
• Poor connection cable connection in the machine's terminal block or mains socket.

maChine errOr COdes

The machine always checks its operation automatically during start-up and reports any
failures detected. If failures are detected during start-up, they are shown as error codes on the
control panel display.

err3: power source overvoltage
Gouging has been interrupted because dangerously high temporary voltage surges or a
continuous over-voltage has been detected in the electric network. Check the fuse size and
the quality of the supply network.
err4: power source overheating
The power source has overheated. The cause may be one of the following:
1. The power source has been used for a long time at maximum power.
2. The circulation of cooling air to the power source is blocked.
3. The cooling system has experienced a failure.
Remove any obstacle to air circulation, and wait until the power source fan has cooled down
the machine.
err23: power source overvoltage warning
The power source has detected voltage spikes in the electric network. Short power spikes can
be managed. They do not lead to interruptions in gouging but may decrease the quality of the
work. Check the quality of the supply network.
Other error codes:
The machine can show codes not listed here. In the event of an unlisted code appearing,
contact an authorised Kemppi service agent and report the error code shown.
