7.4 Test
In case this product is tested, a special setting or operation is not needed fundamentally.
However, the following test should operate it along with each process.
(1) Alarm-output test
Even if this product does not have input, it can perform ON/OFF test of an alarm output (relay-contact output).
Operation is performed by alarm 1 test and alarm 2 test in the setting mode 1.
Please refer to "5.3.1 Setting mode 1 (2) alarm-output setup" about the details of operation.
In case an alarm-output factor is a current leakage (Io/Igr).
While pushing SET, the test input exceeding rated sensitivity current value is applied to the zero-phase
current input circuit inside a product. If the time that is pushing
SET
exceeds the operating time (it exceeds
time-delay form 0.1 seconds, and is 2 or less seconds) of a current leakage, an alarm will occur.
And, test input will become off if
SET
is detached. Please be sure to apply rated voltage to voltage input
terminal (between P1-P2) at this time.
In addition, an alarm return constitutes action corresponding to a return method setting (automatic reset /
manual reset) of each alarm output.
< Operating process >
・Alarm 1 test (Setting № 124)
(111) (121) (124)
Press
SET
for 3 seconds → Press
MODE
→ Press
RESET/SHIFT
for 3 times → While pushing
SET
, the
alarm 1 output is ON.
・Alarm 2 test (Setting № 128)
(111) (121) (128)
Press
SET
for 3 seconds → Press
MODE
→ Press
RESET/SHIFT
for 7 times → While pushing
SET
, the
alarm 2 output is ON.
・In case an alarm-output factor is current leakage (Io/Igr) ･･･ Example ) ALARM 2
(111) (121) (128)
Press
SET
for 3 seconds → Press
MODE
→ Press
RESET/SHIFT
for 7 times
If it continues pushing
SET
for a long time from the current-leakage operating time,
alarm 2 output is ON.
(2) Harmonic time-interval test
Please test by the following operation about the time interval of a harmonic. An error becomes large, in
case it tests without performing the following operation.
Operation is performed with the average time interval in the setting mode 1.
Please refer to "5.3.1 setting mode 1 (4) harmonic detection setting" for operation details.
< Operating process > (Setting № 14A)
(111) (141) (14A)
Press
SET
for 3 seconds → Press
MODE
for 3 times → Press
RESET/SHIFT
for 9 times
Please press
SET
simultaneously with a test start.
Please press
DISPLAY
and return to a measurement screen.
7.5 Storage
(1) Please avoid storage in the next space. Low temperature, high temperature, high humidity, and sunny place.
(2)
The aluminum electrolytic capacitor is used for a product. Please do the energization of the power supply
within one year after shipment.
7.6 Countermeasures against troubles
As our principle, we recall product in question and repair it. If judged as product failure, have a contact with
us or sales agent for repairing work (Also have a contact with us or sales agent for specification change).
Product failure which we are not responsible for (When responsibility in manufacturing process is not recognized,
when product is disassembled/remodeled, in case of false operation by customer, etc.) is beyond our warranty.
