Troubleshooting Warnings and Error Codes
Use the table below to troubleshoot any issues with the machine. If the issue cannot be resolved,
contact Cold Jet at (see Contact Information on page 50). Warnings do not shut down the PLT 60.
Warnings will display in two states: yellow which means that an item is nearing a point that attention
must be given and red: which means that an item needs immediate attention.
Errors generally will cause the PLT 60 to go into idle. An error code will display in the status screen.
An error indicates a serious fault, shutting down the PLT 60 to prevent damage to the system or
an error serious in nature has occurred, in which case you will need to contact Cold Jet Customer
Service. The PLT 60 in error shut down will go into idle only mode.
