Inspection result

Countermeasure

The LED indicator
(OUT1, OUT2, OUT3)
illuminates, but the
relay output is not
activated.

Is the load
fluctuation too
great?

The load fluctuates greatly and
it instantaneously exceeds the
setting level repeatedly.

Set the parameters
(6, 9, 12, and 16)
properly.

The load does not fluctuate and
there is a great difference from
the setting level.

Repair Shock
Monitor.

The relay output is
activated as soon as
Shock Monitor is
turned ON.

Is the motor starts
when Shock
Monitor is turned
ON?

The displayed load is larger
than the setting value.

Set the parameters (6
and 9) properly.

The output is activated even
when the motor is stopped
and the displayed load is 0.
(Shock Monitor is used in a
highly humid environment with
corrosive gas.)

Repair Shock
Monitor.

Reset Procedure

Procedure

(1) Inspect the equipment for any abnormalities.
(2) If an abnormality is found, eliminate the cause and reset the equipment to normal status.
(3) If the relay output is in self-holding status, press the RESET key to reset it. The

reset is also possible by turning off the operational power supply for the Shock Monitor
for a short time.

(4) After confirming steps (1), (2), and (3), restart the equipment.

13. Precautions on Maintenance/Inspection

Be sure to observe the following during the maintenance/inspection work.

(1)

To prevent secondary damage, clean up the surrounding area and ensure safety
during the work.

(2)

Before inspecting the installation or connection of the Shock Monitor, be sure to turn off
the power to make the machine completely stop and the LCD display of the Shock Monitor
completely turn off. Ensure that the Shock Monitor will not be turned on accidentally.

(3)

Observe the guidelines listed in the Labor Safety and Health Regulation.

(4)

When conducting a megger test or dielectric withstanding voltage test, remove the Shock
Monitor main unit from the socket to avoid test voltage.

14. Periodic Inspection

(1)

Inspect that the "MOTOR RUN" LED indicator of the Shock Monitor illuminates while the
motor is running, and the load ratio value on the LCD display is normal. (Daily inspection)

(2)

In the Test mode, inspect the operation of the relay outputs OUT1, OUT2, and OUT3
on a regular basis.

(3)

Inspect for looseness in the installation of the Shock Monitor main unit and current
sensor on a regular basis.

(4)

Inspect for looseness in the terminal connection of the Shock Monitor main unit and
sensor cable connection on a regular basis.

(5)

Although the life of the Shock Monitor varies depending on the installation
environment and operating time, the life of the electrolytic capacitor is normally
about 10 years under continuous energization at annual average ambient temperature
of 30°C. It is recommended to overhaul the Shock Monitor or replace it with a new
one before any problem occurs.

(6)

The brightness of the LCD display varies depending on the ambient temperature and
operating time. If the display becomes illegible, adjust the contrast.

Perform the periodic inspection during trial operation, and when the equipment was

moved, and when the wiring was changed.

15. For Your Safety

(1)

If any danger is expected as a result of the operation of Shock Monitor, be sure to
take measures to avoid such danger.

(2)

Also, give due consideration on the equipment side so that, even if Shock Monitor
does not operate normally, no dangerous situation would develop.
