Chapter 5 Maintenance

In order to use the PLC in the best condition and maintain the system to operate properly, it is necessary to conduct

daily and periodic inspections.

5.1

Daily and Periodic Inspection

(1) Daily inspection

Verify the following items while the system is running.

Table 5.1 Items for daily inspection

Visual check

ON

Power supply error, etc.

RUN

Visual check

OFF:
Microprocessor error, memory error, etc.
Refer to chapter 3 for further information.

OK

*1

Visual check

ON

OFF:
Serious errors such as microprocessor error or
memory error, etc. Refer to chapter 3.
Blink:
Battery error (71 error)

*2

*1

MICRO-EHV+ indicates the error by the lighting pattern (ON / blink / OFF) of OK LED.

*2

If the power isn’t supplied without replacing the battery after battery error detected (OK LED blinking), retain data and
realtime clock data could be lost due to battery empty. If power off time is long enough, it is possible that a battery
becomes empty while this power failure. In that case, retain data and realtime clock data would be already lost in the
next power up.

(2) Periodic inspection

Turn off the power for the external I/O circuit, and check the following items once every six months.
