Relay Design and Specifications

Built-In Testing

The TPU-2000R continuously checks itself for proper functioning.

Self-Test Status

The TPU-2000R provides continuous self-testing of its power supply voltages, memory elements, digital signal processor
and its program execution. In the event of a system failure, the protective functions are disabled and the Self-Check
Alarm contacts are actuated. Except for a “processor stalled” condition, review the PASS/FAIL status of these self-test
elements by using the man-machine interface (MMI). Normal status is indicated by a green TPU STATUS light (LED)
and system failure is indicated by a red TPU STATUS light (or by the green TPU STATUS light not being lit in the case
of a loss of control power).  If the green light is flashing, refer to the Operations Menu in Section 9.

Self-Test Failures are recorded as a number in the Operations Record. The binary bit pattern of this number indicates
the Self-Test Failure or Editor Access Status involved. The 1’s in the bit pattern indicate where a failure has occurred.
Count from the right of the bit pattern (starting with zero) to the position where a “1” occurs. Compare that bit position
with Table 4-1 to reveal the failure. See the following examples for further explanation.

If the self-test fails, the TPU-2000R is no longer providing protection. Replace the unit as soon as possible.
