Software and hardware problems are covered in the troubleshooting chart. Pick the problem that
most closely resembles your problem and review the possible symptoms and corrective action.
Software or system performance problems can and are affected by the supply air system,
exhaust air system, or physical configuration of the room. Separating TSI system problems from
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: These tests require power to the units, so if unit has no power, refer to
hardware troubleshooting chart to eliminate power problem.
Enter Diagnostics menu and check the following:
 Flow Control
 Temperature Control
 Analog Outputs
 Relay Outputs
 View Inputs
 View Outputs
Test - Flow Control
Enter the Flow Control item in the Diagnostics menu to manually manipulate the supply and
exhaust flows.
The RPC30 will not maintain room pressure differential, flow rates or temperature
control while in the Flow Control item.
