A relay test is carried out sufficiently before shipment,
but at the following cases, it is recommended the test
should be carried out again.
a.
When the products are delivered and unpacked
b.
At the time of starting operation of equipment
c.
At the time of periodic inspection (Usually once a
year)
1. At the time of testing
①
The input waveform should be a sine wave with little
distortion.
②
During the test, set the position of the indicator
select switch to "V MEASURE". Set the other setting
switches according to the test conditions of the
operating characteristic control point.
③
If user-defined control point is specified (e.g.
accuracy of relay characteristic is controlled at
service conditions), execute the test at the
manufacturer-defined characteristic control point
before in-service operation and then check accuracy of
the relay. After that, execute the test at the user-
defined control point, and use this data as a later
reference.
2. Withstand voltage test
a. Apply 2000V AC (commercial frequency) between all
circuits and external box (fixing screw for mounting)
for one minute, and make sure that there is no problem.

b. Apply 2000V AC (commercial frequency) between separate
circuits for one minute, and make sure that there is
no problem.

3. Operation characteristics test
①
When the rated voltage is applied, the RUN display LED
(green) lights up. This indicates that the relay works
properly.
②
When adjusting the test voltage during the operating
time test, it is recommended to press the CPU reset
button to lock the operation of this relay. If the
operation is locked and the test voltage is adjusted,
an accurate test is possible.
③
By turning the indicator select switch to "TEST" and
pushing "TEST" button for 2 seconds or more, output
contact can be forced to operate (except for the case
of LOCK setting).
4. Operation characteristic control point
