Safety Precautions
!
WARNING
Always verify the operation of the safety functions before
starting the system. Not doing so many result in the safety
functions not performing as expected if the wiring or
settings are incorrect or the switches have failed.
Do not drop the switch. Doing so may damage the switch
and the system may continue to operate, possibly
causing injury or death.
Edge Controller
Serious injury may possibly occur due to breakdown
of safety outputs.
Do not connect loads beyond the rated value to the
safety outputs.
Serious injury may possibly occur due to loss of
required safety functions.
Serious injury may occur due to loss of required
safety functions. Do not use the Safety Edge with
logics that the operation of the mat might turn ON the guarded
equipment. Use the Safety Edge with logics by which safety
outputs turn OFF in a hazardous state.
Serious injury may possibly occur due to loss of
required safety functions.
Wire the Edge Controller properly so that supply
voltages or voltages for loads do NOT touch the
safety outputs accidentally.
Safety Edge
Serious injury may possibly occur due to loss of
required safety functions.
When using a safety edge, design a safety system
counting the velocity and weight of detecting objects.
Edge Controller
(1) Be sure to turn OFF the power before performing wiring. Do not
touch any of the terminals while the power is being supplied. Doing
so may result in electric shock.
(2) Do not perform wiring when there is a risk of lightning. Doing so
may result in electric shock.
(3) Apply the specified voltage to input terminals. Applying a different
voltage may prevent proper operation and may result in product
damage or burning.
(4) Use a power supply of the specified voltage. Do not use power
supplies with large ripples or power supplies that intermittently
generate incorrect voltages.
(5) Do not under any circumstances, use the product for loads that
exceed the product's contact ratings, such as the switching
capacity (switching voltage and switching current.) During so may
not only result in faulty insulation, contact deposition, contact
failure, or other problems affecting product performance, it may
also result in damage or burning.
(6) Relay durability depends greatly on the switching conditions.
Confirm operation under the actual conditions in which the Relay
will be used. Make sure the number of switching operations is
within the permissible range. If a Relay is used after performance
has deteriorated, it may result in insulation failure between circuits
and burning of the Relay itself.
(7) Do not use the product in locations subject to explosive or
flammable gases. Doing so may cause combustion or explosion
due to Relay heating or arcing during switching.
(8) Do not drop the product or use components that have been
disassembled. Doing so may not only adversely affect
performance characteristics, it may also result in damage.
(9) Connect a fuse to the Switch in series to protect the Switch from
short-circuit damage or ground faults. Not doing so may result in
damage.
Safety Edge
(1) Be sure to turn OFF the power before performing wiring. Doing so
may result in electric shock.
(2) Do not perform wiring when there is a risk of lightning. Doing so
may result in electric shock.
(3) Do not use the product in locations subject to explosive or
flammable gases. Doing so may cause combustion or explosion
due to Relay heating or arcing during switching.
(4) Do not drop the product or use components that have been
disassembled. Doing so may not only adversely affect
performance characteristics, it may also result in damage.
