MAINTENANCE AND INSPECTION
In order that you can use the PLC in normal and optimal condition at all times, this
section describes those items that must be maintained or inspected daily or at regular
intervals.
CAUTION
The online operations performed from a PC to a running safety
PLC (Program change when a safety CPU is RUN, device test,
and operating status change such as RUN-STOP switching) have
to be executed after the manual has been carefully read and the
safety has been ensured.
Following the operating procedure predetermined at designing, the
operation has to be performed by an instructed person.
When changing a program while a safety CPU is RUN (Write
during RUN), it may cause a program breakdown in some
operating conditions.
Fully understand the precautions described in the GX Developer's
manual before use.
Do not disassemble or modify the modules.
Doing so could cause a failure, erroneous operation, injury, or fire.
If the product is repaired or remodeled by other than the specified
FA centers or us, the warranty is not covered.
Use any radio communication device such as a cellular phone or a
PHS phone more than 25cm (9.85 inch) away in all directions of
the PLC.
Not doing so can cause a malfunction.
Completely turn off the externally supplied power used in the sys-
tem before mounting or removing the module.
Not doing so may result in a failure or malfunctions of the module.
Restrict the mounting/removal of a module, base unit, and terminal
block up to 50 times (IEC61131-2-compliant), after the first use of
the product.
Failure to do so may cause the module to malfunction due to poor
contact of connector.
Do not drop or give an impact to the battery mounted to the
module.
Doing so may damage the battery, causing the battery fluid to leak
inside the battery.
If the battery is dropped or given an impact, dispose of it without
using.
Before touching the module, always touch grounded metal, etc. to
discharge static electricity from human body, etc.
Not doing so may result in a failure or malfunctions of the module.
