Introduction
♦ Machine in which this device is installed
● When this device is used in "PSDI mode", an appropriate control circuit must be config-
ured between this device and the machine. For details, be sure to refer to the standards
and regulations applicable in each region or country.
● In Japan, do not use this device as a safety device for press machine.
● Do not install this device with a machine whose operation cannot be stopped immediately
in the middle of an operation cycle by an emergency stop equipment.
● This device starts the performance after 2 seconds from the power ON. Have the control
system started to function with this timing.
♦ Wiring
● Be sure to carry out the wiring in the power supply OFF condition.
● All electrical wiring should conform to the regional electrical regulations and laws. The wir-
ing should be done by engineer(s) having the special electrical knowledge.
● Do not run the wires together with high-voltage lines or power lines or put them in the
same raceway. This can cause malfunction due to induction.
● In case of extending the cable of the emitter or the receiver, each can be extended up to
70m by using the exclusive cable. Taking cable voltage drop into account, the cable length
differs according to the source current / sink current of the control output (OSSD1 / 2). For
details, refer to "6-1 Specifications". Using a cable length outside the specifications may
cause the device to malfunction, possibly resulting in death or serious injury.
● Do not apply stress such as excessive bending or pulling to a cable or the extracted part of
a cable. In particular, when the temperature is low, cable materials harden, and when the
temperature is high, the materials soften, and so take care that cables may break if they
are subject to stress such as bending or pulling when the temperature is low or high.
● Do not control the device only at one control output (OSSD 1 / 2).
● In order that the output is not turned to ON due to earth fault of the control output (OSSD 1
/ 2) wires, be sure to ground to 0V side (PNP output) / +V side (NPN output).
● When using this device in Korea with S-mark, be sure to ground to 0V side (PNP output).
♦ Maintenance
● When replacement parts are required, always use only genuine supplied replacement
parts. If substitute parts from another manufacturer are used, the device may not come to
detect, result in death or serious injury.
● The periodical inspection of this device must be performed by an engineer having the spe-
cial knowledge.
● After maintenance or adjustment, and before starting operation, test this device following
the procedure specified in "Chapter 4 Maintenance".
● Clean this device with a clean cloth. Do not use any volatile chemicals.
♦ Others
● Never modify this device. Modification may cause the device not to detect objects, result-
ing in death or serious injury.
● Do not use this device to detect objects flying over the detection area.
● Do not use this device to detect transparent objects, translucent objects or objects smaller
than the specified minimum object to be detected.
