5.6 Initialization and Power-On Self-Test (POST)
State
To start the CHPA, turn on the Main Power circuit breaker. The microprocessor controller will
perform self-tests and CHPA tests. Once these tests are completed successfully, the user will
have control over the CHPA. After prime power is applied to the unit, the control panel
displays the following:
C P I S A T C O M
6 0 0 / 7 0 0 C H P A
P O W E R O N S E L F T E S T
Once communication with the CHPA controller is established, the control panel displays the
following:
C P I S A T C O M
6 0 0 / 7 0 0 C H P A
P O W E R O N S E L F T E S T
T E S T I N G
While the POST screen is displayed, all self-tests are performed.
If the front panel fails to establish communications with the controller, the panel will report a
communications failure. POST failure is reported as follows:
C P I S A T C O M
6 0 0 / 7 0 0 C H P A
P O S T F A U L T T E S T # 1
A / D C A L I B R A T I O N
During POST the microprocessor controller performs tests that check the integrity of the
microprocessor controller hardware, software, and CHPA subsystems. Each test is assigned a
number for troubleshooting purposes. In the event of a POST Fault, the fault will be indicated.
(See Appendix B Table B-13.) At the successful completion of the POST, the CHPA will
automatically enter the HTD state.
