Safety Precautions
10 CK3E-series Programmable Multi-Axis Controller Hardware User’s Manual (I610)
WARNING
During Power Supply
Do not attempt to take any Unit apart.
In particular, high-voltage parts are present in the product while power is supplied or imme-
diately after power is turned OFF. Touching any of these parts may result in electric shock.
There are sharp parts inside the Unit that may cause injury.
Fail-safe Measures
Provide safety measures in external circuits to ensure safety in the system if an abnormality
occurs due to malfunction of the system due to other external factors affecting operation.
Not doing so may result in serious accidents due to incorrect operation.
Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must
be provided in external control circuits.
You must take fail-safe measures to ensure safety in the event of incorrect, missing, or
abnormal signals caused by broken signal lines, momentary power interruptions, or other
causes. Not doing so may result in serious accidents due to incorrect operation.
The use of an Uninterruptible Power Supply (UPS) allows normal operation to continue
even if a momentary power interruption occurs, possibly resulting in the reception of an
erroneous signal from an external device affected by the momentary power failure. Take
external fail-safe measures. Where necessary, monitor the power supply voltage on the
system for external devices and use it as an interlock condition.
Unintended behavior may occur when an error occurs in internal memory of the product.
As a countermeasure for such problems, external safety measures must be provided to
ensure safe operation of the system.
The Controller will turn OFF all outputs from Output Units in the following cases. The slaves
will operate according to the settings in the slaves.
• If a power supply error occurs
• If the power supply connection becomes faulty
• When a CPU error (watchdog timer error) or CPU reset occurs
• If a Controller error in the major fault level occurs
• While the Controller is in startup status until RUN mode is entered after the power 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.
