[Startup and Maintenance Precautions]
● Do not touch any terminal while power is on. Doing so will cause electric
shock or malfunction.
● Shut off the external power supply for the system in all phases before cleaning
the module or retightening the screws on the terminal block or connector
screws. Failure to do so may result in electric shock.
[Startup and Maintenance Precautions]
● Before performing online operations (especially, master station program
modification, forced output, and operation status change) for a running head
module from the peripheral connected, read relevant manuals carefully and
ensure the safety. Improper operation may damage machines or cause
accidents.
● Do not disassemble or modify the modules. Doing so may cause failure,
malfunction, injury, or a fire.
● Use any radio communication device such as a cellular phone or PHS
(Personal Handy-phone System) more than 25cm away in all directions from
the programmable controller. Failure to do so may cause malfunction.
● Shut off the external power supply for the system in all phases before
connecting or disconnecting the module. Failure to do so may cause the
module to fail or malfunction.
● Tighten the screws on the terminal block or connector screws within the
specified torque range. Undertightening can cause drop of parts or wires,
short circuit, or malfunction. Overtightening can damage the screw and/or
module, resulting in drop, short circuit, or malfunction.
● After the first use of the module, the number of module
connections/disconnections is limited to 50 times. Exceeding the limit (in
accordance with IEC 61131-2) may cause malfunction.
● Before handling the module, touch a conducting object such as a grounded
metal to discharge the static electricity from the human body. Failure to do so
may cause the module to fail or malfunction.
Precautions for using positioning modules
● Before testing the operation by the positioning module, set a low speed value
for the speed limit parameter so that the operation can be stopped
immediately upon occurrence of a hazardous condition.
