Test 14 – Radio Frequency (RF) communication errors
The 0-98-1 and 0-98-2 fault codes identify different types of Radio Frequency (RF) communication
problems.
0-98-1 fault: cartridge or torch
If a new Hypertherm cartridge does not cause the 0-98-1 fault to go away, there can be a problem
with the antenna on the torch PCB or the wires that connect to the antenna. Do the following:
1. Disconnect the SmartSYNC torch from the plasma power supply.
2. Put the torch on its side. Remove the left side of the torch shell.
3. Are the 2 antenna wires securely connected to the torch PCB?

If yes, continue with the next step.

If no, adjust the antenna wires as necessary until they connect fully and securely in the
connector on the torch PCB.
4. Disconnect the 2 antenna wires from the torch PCB, as follows:
a. Lightly push down the tabs on the antenna connector on the
torch PCB with your thumb or fingers. You can also use a
tool to push down the tabs if the points are not too sharp.
The pliers shown to the right are one example.
b. While you hold down the tabs, pull the antenna wires out of
the connector.
5. With the antenna wires disconnected,
measure the resistance of the antenna
coil in the connector on the torch PCB.
Is the resistance less than 1 ohm (Ω)?

If yes, the antenna wires have
possible damage. Replace the torch
body.

If no, the antenna on the torch PCB
has possible damage. Replace the
torch PCB.
