WARNING
Use only appropriate components or devices
complying with relevant safety standards
corresponding to the required performance level and
safety category. Failure to do so may result in serious
injury or death. Conformity to requirements of the
performance level and safety category must be
determined as an entire system. It is recommended to
consult a certification body regarding assessment of
conformity to the required safety level.
Do not apply DC voltages exceeding the rated
voltages, nor any AC voltages to the product.
Failure to do so may result in serious injury or death.
Install the switch and actuator in a position where the
opening of the guard door can be detected within a
safe distance. Failure to do so may result in serious
injury or death.
When complying with safety standards, install the
product in an appropriate manner in accordance with
ISO 14119, with due consideration of the risk of defeat
by the operator. Failure to do so may result in serious
injury or death.
Make sure that the DC power supply meets the
following items. Failure to do so may result in serious
injury or death.
- Satisfies the requirements of PELV power supply
defined in IEC 60204-1.
- Satisfies the requirements of class 2 circuits defined
in UL508.
Precautions for Safe Use
1. Disconnect the product from power supply when wiring the
product. Failure to do so may cause unexpected operation of
devices connected to the product.
2. Wire the input and output terminals correctly and verify the correct
operation of the product before using the system in which the
product is incorporated. Incorrect wiring may lead to loss of the
safety function.
3. Do not use the product in any direction other than the specified
mounting orientations of the main body and actuator.
4. Dispose of the product in accordance with the laws set by each
country.
Precautions for Correct Use
1. Do not drop the product to the ground or expose to excessive
vibration or mechanical shocks. Doing so may damage the product
and cause failure.
2. Do not store or use the product under the following conditions.
Doing so may damage the product and cause failure.
1) At ambient operating temperatures out of the range of -25 to
65°C
2) At ambient storage temperatures out of the range of -25 to
85°C
3) At relative humidity of 93% or more
4) In direct sunlight
5) Under drastic temperature changes
6) In high humidity that causes condensation
3. Keep the product away from oil or solvent.
Oil or solvent make the marking on the product illegible and cause
deterioration of some parts.
4. Do not use in an environment with corrosive gas.
5. The product may not operate normally in the vicinity of devices that
generate strong radio waves or magnetic fields, such as RFID
systems, proximity sensors, motors, inverters, and switch-mode
power supplies. If the device is used in the vicinity of such devices,
check the effect before use.
6. Installing the switch and the actuator on a metallic material may
affect the operating distance. If installation on a metallic material
is necessary, be sure to check the effect on the operating distance
before use.
7. Tighten the screws with a specified torque.
8. Use the wires specified by OMRON to wire the product.
(Refer to Connection on page 9.)
9. Do not extend the cables in excess of the specification of this
product. Carry out electrical connection according to the wiring
examples shown in this document and verify the correct operation
of the product.
10.During installation, make sure that the safety door switch does not
come in contact with the actuator due to rattling of the guard door.
(The performance of the product may be degraded by a collision
caused by opening or closing the guard door.)
11.Do not pull or bend the cable excessively.
A disconnection may cause a malfunction.
12.Risk time remains unchanged by series connection. However,
carry out electrical connection according to the wiring examples
shown in this document.
13.Be sure to inspect the product daily and every 6 months. Failure to
do so may cause a system failure and serious injury.
14.When determining the safety distance, take into account the delay
of the output of the product caused by the response time. Failure
to do so may cause the operator to reach the hazardous source
before the machine is stopped, resulting in serious injury.
15.Install the product so that the LED indicators of the safety door
switch are as visible as possible. Misinterpreting the status of the
safety door switch may result in danger.
16.Do not use the product at an altitude of 2,000 m or higher.
17.Do not connect a product different from this product in series with
this product. Doing so may disturb waveforms of the input and
output signals, leading to loss of the safety function.
18.Do not use the product in the water or continuous water exposure
environment. Doing so may cause water to leak into the product.
(The degree of protection does not guarantee the protection under
continuous water exposure environment.)
