♦ Machine in which this device is installed
● When this device is used in the "PSDI Mode," an appropriate control circuit must be con-
figured between this device and the machinery. For details, be sure to refer to the stan-
dards or regulations applicable in each region or country.
● In Japan and Korea, do not use this device as safety equipment for a press machine.
● Do not install this device with a machine whose operation cannot be stopped immedi-
ately 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
wiring 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 50m by using the exclusive cable. Furthermore, if the cable is extended in the state
that the device is in series connection, or the muting lamp is used, the total extendable
length of the cable depends on the number of the devices in series connection. For
details, refer to "2-5-3 Wiring · Connecting Procedure and Connector Pin Arrange-
ment."
● 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) / +24V side (NPN 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
special knowledge.
● After maintenance or adjustment, and before starting operation, test this device fol-
lowing 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, resulting in
death or serious injury.
● Do not use this device to detect objects flying over the sensing area.
● Do not use this device to detect transparent objects, translucent objects or objects
smaller than the specified minimum sensing objects.
