Warnings
WARNING
Disassembly and Dropping
Do not attempt to disassemble, repair, or modify the product in any way. Do-
ing so may result in malfunction or fire.
Installation
Always connect to a ground of 100 Ω or less when installing the product.
Ensure that installation and post-installation checks of the product are per-
formed by personnel in charge who possess a thorough understanding of
the machinery to be installed.
Fail-safe Measures
Provide safety measures in external circuits to ensure safety in the system if
an abnormality occurs due to malfunction of the product or due to other ex-
ternal factors affecting operation. Not doing so may result in serious acci-
dents due to incorrect operation.
Emergency stop circuits, interlock circuit, limit circuits, and similar safety
measures must be provided in external control circuits.
The product will turn OFF all outputs from Output Units in the following cas-
es. The slaves will operate according to the settings in the slaves.
•
If an error occurs in the power supply
•
If a CPU watchdog timer error or CPU reset occurs
•
If a major fault level Controller error occurs
•
While the product is on standby until RUN mode is entered after the pow-
er is turned ON
•
If a system initialization error occurs
External safety measures must be provided to ensure safe operation of the
system in such cases.
If external power supplies for slaves or other devices are overloaded or
short-circuited, the voltage will drop, outputs will turn OFF, and the system
may be unable to read inputs. Provide external safety measures in controls
with monitoring of external power supply voltage as required so that the sys-
tem operates safely in such a case.
Unintended behavior may occur when an error occurs in internal memory of
the product. As a countermeasure for such problems, external safety meas-
ures must be provided to ensure safe operation of the system.
