[Design Precautions]
CAUTION
●
During the control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on. Take
proper measures so that the flowing current dose does not exceed the value corresponding to the
maximum load specification of the resistance load.
●
Turn on the power supply of an FX5 CPU module and a safety extension module simultaneously
(within two seconds). When a connection error still occurs even if the power supplies are turned on
simultaneously, review the power supply environment of the FX5 CPU module and the safety
extension module.
When the power is supplied for a programmable controller and other devices from the same power
supply system, wire the system separately so that the programmable controller and the other devices
can turn on and off individually.
When a connection error occurs, check the error code, turn OFF the power supply of the CPU module
and the safety extension module once, and then turn ON the power supplies simultaneously.
●
Ensure that an entire system using a safety extension module meets the requirements for the
corresponding safety category.
●
Leave the following space between a programmable controller and equipments (such as a contactor
and relay), external device wiring, or power cables to avoid the effect of radiated noise and heat.
• Wiring: 100 mm or more
• Device: 50 mm or more
●
If a mechanical switch such as a relay is connected to an input terminal of the safety extension
module, consider contact bounce.
