Confirming physical installation is correct
All of the hardware components need to be installed properly. Review the installation
instructions and verify components are installed properly at the correct location. This is easily
done when the wiring is checked.
Verifying mechanical components
Verifying all TSI components are operating correctly requires following a simple procedure.
The fastest procedure to confirm all equipment is operating is to first test the Digital Interface
Module (DIM), and then go into the diagnostic menu to test each component.
NOTE: These tests require power to the units, so if unit has no power, refer to hardware
troubleshooting chart to eliminate power problem.
TEST - DIM
Enter the SELF TEST menu item in the diagnostics menu to verify DIM electronics are
functioning correctly. During the self test, the display will show the model number and
software revision of the controller. At the end of the self test, the display will show a
message. The display shows:
NO ERRORS if all DIM electronics are good.
FRAM error if settings may have been lost. Press RESET to clear error and check all
settings for correct values.
CALIB error if sensor calibration may have been lost. Verify face velocity, sash sensor
and/or flow calibration.
If NO ERRORS is displayed, proceed to test individual components in the Diagnostics Menu.
If the controller passes each of the tests, the mechanical piece parts are all functioning
correctly.
