TC300 Heater Temperature Controller Chapter 6: Stand-Alone Operation
Rev B, January 5, 2022 Page 21
6.12. Error Handling
There are two types of alarm messages for the TC300, Warnings and Errors. A warning indicates a state in which
any enabled channel of the TC300 will continue to work but there are some operation parameters that are out of
range; thus, optimum performance cannot be guaranteed. An error is a state in which a critical failure occurred and
all channels of the TC300 are disabled. The error and warning messages will be shown on the top right corner of
the main screen. It is possible to have multiple warnings and errors occurring simultaneously.
