TC300 Heater Temperature Controller Chapter 6: Stand-Alone Operation

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.

Warning HIGH TEMP1
The measured temperature on CH1 is higher
than the user defined maximum temperature.
Make sure both sensor and
heater are correctly
connected to the TC300 and
configured according to
datasheets.
Warning LOW TEMP1
The measured temperature on CH1 is lower
than the user defined minimum temperature.
Warning HIGH TEMP2
The measured temperature on CH2 is higher
than the user defined maximum temperature.
Warning LOW TEMP2
The measured temperature on CH2 is lower
than the user defined minimum temperature.
Warning TRIG IN CH1
User trying to enable CH1 when the trigger of
CH1 is set to inpu
t
Set the trigger to output or
use an external signal
source to enable/disable the
channels of the TC300
Warning TRIG IN CH2

Power cycle the device. If
warning continues to occur,
contact tech support.

Make sure both sensor and
heater are correctly
connected to the TC300 and
configured according to
datasheets.
