Hardware Test - Pressura RPM10 Operation And Service Manual

the laboratory HVAC system can sometimes be difficult. TSI recommends confirming all
hardware is operating correctly before troubleshooting software problems.

Hardware Test

Three tests need to be performed in order to determine all hardware is functioning correctly. The
tests are broken down into:

Confirming wiring is correct.

Confirming physical installation is correct.

Verifying mechanical components.
Confirming wiring is correct
The most common problem with installed hardware equipment is incorrect wiring. This problem
usually exists on initial installation, or when modifications to the system take place. The wiring
should be very closely checked to verify it exactly matches the wiring diagram. Wiring diagrams
are located in Appendix C of this manual. Wiring associated with non-TSI components should be
closely checked for correct installation. If non-TSI components are installed, consider
disconnecting them for testing purposes.
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:
Test – Analog Outputs
Enter the Analog Outpt item in the Diagnostics menu to manually manipulate the analog outputs.

Touch the Output 1, Output 2, Output 3 button to manually set the output signal.
Technical Section
These tests require power to the units, so if unit has no power, refer to
hardware troubleshooting chart to eliminate power problem.
