Built-InTesting
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.

Example of a Self-Test Failure
Value : 256 has a binary bit pattern of 0000000100000000 (bit order 15........0)
The 1 is in bit position 8 as you count from the right. This bit position correlates to DSP ROM failure.
Example of an Editor Access
Value : 145 has a binary bit pattern of 0000000010010001 (bit order 15.........0)
The 1’s in this bit pattern have the following bit positions and corresponding Editor Access Status:
Bit 0 : Interrupt logging bit (Ignore this bit because it will always be set in this example.)
Bit 4 : Front communications port initiated the editor access and change.
Bit 7 : Real-time clock settings were changed.
TPU-2000R Settings Tables Diagnostics
Three copies of each settings table are stored in nonvolatile memory, preventing data loss during control power
cycling. When you finish editing any settings table, the changed table’s data is transferred from a temporary edit
buffer into three separate locations in nonvolatile memory.
A background diagnostics task continuously runs a checksum on each copy of the settings tables to verify data
consistency. If an invalid copy is detected, the diagnostic task attempts self-correction by transferring a valid copy to
the invalid copy location. If this is unsuccessful, the task marks the copy as unusable and switches to the next
available copy.
When the TPU-2000R detects that all three copies of a settings table are not valid, the diagnostic task adds a self-
diagnostic error in the Operations Record, drops the self-check alarm, and disables all protective functions. In
addition, the Self Test display under the MMI Test Menu shows the current status (PASS or FAIL) for all memory
devices.

Interfacing with Relay
Man-Machine Interface (MMI)
The man-machine interface (MMI) on the front panel consists of a four-line
liquid crystal display (LCD) with twenty characters per line, six push-buttons
(keys) and thirteen LED targets. Press the Enter <E> key to access the
Main Menu. Use the up and down arrow keys to move through the various
menus and to change the character value when you enter the alphanumeric
password. Use the Enter <E> key to select the desired menu or desired
value when you change settings.
Use the left and right arrow keys to decrease and increase, respectively,
setting values or record numbers. You can also use them to move from left
to right within the password string. Hold down or repeatedly press the arrow
keys to change the setting value.
Use the clear <C> key to return to the previous menu. You can also use the <C> key to:
• reset LED targets and the LCD after a fault (push <C> once)
• scroll through all metered values (push <C> twice)
• reset the peak demand values (push <C> three times)
Perform a system reset by simultaneously pressing the <C>, <E> and up arrow keys. This resets the
microprocessor and re-initiates the software program. During a system reset, no stored information or settings are
lost.
The following displays and menus are available through the MMI:
• Continuous Display—the enabled settings table and all currents
• Post-Fault Display—fault currents for last fault until targets are reset
• With optional VT inputs installed, Continuous Display and Post-Fault Display show currents and voltages
