Operation and maintenance
All units require periodically check and maintenance. When you check, be careful about the following matters.
Note for Electrostatic discharge
Static electricity is accumulated in human body. It causes electrostatic discharge and destroys sensitive
electric devices (LSI, IC, etc) easily. To discharge static electricity, before touching unit, touch the metal
connected with earth. Use electrostatic hazard shoes, ESD wristband. Do not touch any electrode or metal
part of unit. Especially, be careful when you connect/disconnect programming cable.
Do not install/remove Expansion I/O unit while unit power is ON
When you install/remove Expansion I/O unit, turn OFF power supply of the PMIU unit.
Do not insert finger, wire, tool tip etc. into unit case
Unit case has heat radiation hole, connector hole etc. The invasion of these may cause malfunction of unit,
fire or electrical shock.

Maintenance items
LED status
When PMIU unit is operating normally, POWER LED is lit.
Screen
Screen of PMIU unit should be clean. If there is dirt, wipe with clean closes.
Installation state
PMIU unit should be fixed to panel surely, and Expansion I/O units should be attached to PMIU unit surely.
There must not be loosening in the installation.
Connected wires and wire terminals
All connectors and terminal blocks should be installed surely, all wire should be appropriate slack. Wire
covering, connector or terminal block must not be discoloration or damage, wire terminal must not be dirt or
discoloration.
The discoloration of the metal might have been caused because of an abnormal current/voltage or
overheating.
The
dirt/scorching
of
connector,
wiring
terminal
and
of
surroundings
might
cause
the
short-circuit accident. Note that wire covering that passes a long term becomes hard and is damaged easily.
Project (software) backup
We recommend periodically backup of project for an unexpected memory loss (it may be caused by strong
EMC noise, lightning accident, etc). You can Online or Upload project freely while unit power is ON and unit
mode is RUN mode.
