Control System Design
● Interlock circuits and other circuits such as emergency stop, conventional protection,
forward and reverse rotation must be set outside the product; devices for preventing
equipment damage (up, down and reciprocating movement limit) must be set outside
the product.
● A fault protection circuit must be laid outside the to prevent unexpected mechanical
movement caused by, for example, errors in the non‑detectable I/O control area.
● A user program must be designed to inform users of faults concerning the display,
control, communication, power supply and so on, ensuring safety of the user system.
● Make sure that measures have been taken to avoid malfunction caused by the
communication faults between the product and the master controller. This is to prevent
personal injury and equipment damage.
● Do not bring live parts into contact with the metal enclosure of the product.
● Do not create, on the touch screen of the HMI, switches that may result in personal injury
of the operator or equipment damage . Use independent switches for performing critical
operations. Failure to comply may result in accidents caused by wrong outputs or faults.
● Do not create switches that are used to control equipment safety operations on the
touch screen, such as the emergency stop switch. Use independent hardware switches to
perform safety‑related operations. Failure to comply may result in series personal injury
or equipment damage.
● Do not use this product as an alarm device to report critical alarms that may cause
severe personal injury, equipment damage or system stop. Use an independent hardware
and/or mechanical interlock to design a mechanism for reporting critical alarms and the
related control/triggering devices.
