Onboard Diagnostics
The TX-6-HS monitors all critical functions of the unit through software diagnostics that continuously test and verify unit operations. If a
problem is found, the unit will switch to a fail-safe/error mode or trouble condition. In this error mode, the Fan and Alarm relays will be
activated, the 4-20 mA current loop will go to 24 mA, the unit will display the error code and the buzzer will chirp intermittently. This is a
safety precaution. To clear this mode, simply turn off power to the unit for a few seconds, or push the ENTER/TEST switch (inside the
unit). This will cause the unit to restart the 1 minute self-test cycle.
