Electrically Testing Part Heaters and Needle Heaters
1. In the FmNT Main Window, click on Tools.
2. In the Tools Window, click on Terminal.
3. Click on Heaters.
4. In the Heater Control Window, locate the loops (channels) for the Heater
Tooling installed on your system

Console and switch the Main Circuit Breaker OFF (0). Lock out and tag out the
power as specified in the Safety section of this manual.
7. Open the Hatch and disconnect the electrical cable to each Heater Module.

and 2 for each Heater Module.
 The resistance for a Heater with one heating element should be 60 ohms.
 The resistance for a Heater with two heating elements should be 30 ohms.
 If the Heater Tooling does not meet the resistance requirements, it should
be repaired or replaced before proceeding.
9. Reconnect the electrical cables, and close the Hatch.
