6.5 Function
Test
CAUTION
The function test may cause the output relays to operate including the tripping output relays.
Therefore, the test must be performed with tripping circuits disconnected.
6.5.1 Measuring
Element
Measuring element characteristics are realized by software, so it is possible to verify the overall
characteristics by checking representative points.
Operation of the element under test is observed by the binary output signal at monitoring jacks A
or B or by the LED indications above the jacks. In any case, the signal number corresponding to
each element output must be set on the "Logic circuit" screen of the "Test" sub-menu.

When a signal number is entered for the Term A line, the signal is observed at monitoring jack A
and when entered for the Term B line, it is observed at monitoring jack B.
Note:
The voltage level at the monitoring jacks is +5V for logic level "1" and less than 0.1V for
logic level "0".
CAUTION
•
Use test equipment with more than 1 k
Ω
of internal impedance when observing the output
signal at the monitoring jacks.
•
Do not apply an external voltage to the monitoring jacks.
•
Do not leave the A or B terminal shorted to 0V terminal for a long time.
In case of a three-phase element, it is sufficient to test for a representative phase. The A-phase
element is selected hereafter.
Note: Operating time test of measuring relay elements at monitoring jack A or B is not
including the operation of binary output. Whole the operating time test, if required,
should be measured at a binary output relay.
