Figure 2-7. Self-Test Function Block Diagram

If an error is detected, the GO indicator goes out and the NO-GO indicator remains on. The self-test error signal causes

the self-test routine to loop on the card ID where the failure occurred. To get out of this loop, the operator must press the

SELF-TEST switch on the front panel. If the self-test procedure is completed with no errors detected, the NO-GO

indicator goes out and the GO indicator remains, on. When the self-test is completed, the timing and control function

applies the card/self-test complete signal to the self-test detect logic. The self-test detect logic then generates an internal

self-test complete signal and stops the self-test function.
