Don’t close the control line or communication cable to main circuit or power line. Distance should be more
than 100mm. It may cause malfunction by noise.
In case of controlling lamp load, heater, solenoid valve, etc. in case of Off -> On, large current (10 times of
normal current) may flows, so consider changing the module to module that has margin at rated current.
Process output may not work properly according to difference of delay of Controller main power and
external power for process (especially DC in case of) Controller power On-Off and of start time.
For example, in case of turning on Controller main power after supplying external power for process, DC
output module may malfunction when Controller is on, so configure the circuit to turn on the Controller main
power first
Or in case of external power error or Controller error, it may cause the malfunction.
Not to lead above error to entire system, part causing breakdown of machine or accident should be
configured at the external of Controller.
