PREVENTING MUTUAL INTERFERENCE BY DEVICE PLACEMENT
●
This section describes methods for placing 2 or more sets of emitters and receiv-
ers facing each other, rather than in a series or parallel connection. Consider
these when there is a wiring problem or you need to test the system in conjunction
with changes such as adding new equipment.
Use a test rod to perform an operation test.
WARNING
●
Refer to and understand the examples of device placement given below before
installing the devices. Risk of death or serious injury if the devices are not placed
correctly.
●
When using multiple sets of the device, install so as to avoid mutual interference.
Risk of death or serious injury if mutual interference occurs.

WARNING
The emitter and receiver cables must be oriented in the same direction. Risk of
malfunctioning if the cables are not in the same oriented in the same direction.

MOUNTING
CAUTION
●
The minimum bending radius of the cables is R6mm. Keep the minimum bending
radius of the cables in mind during installation.
●
Do not apply stress such as excessive bending or pulling to the extracted part of
a cable.
●
After installing this device, be sure to adjust the beams so that the device's sta-
ble light reception indicator lights green and the number “3” lights green on the
digital indicator. To adjust the beams, refer to the manual on our website.
When using as a safety device for a press machine or paper shearing machine in Japan
(Applicable model: SF4D-□-01)
WARNING
●
When using as a safety device for a press machine or paper shearing machine
in Japan, always attach the protective tube
SFPD-A10
(option) to the cable.
●
The minimum bending radius of the cable with the protective tube
SFPD-A10
at-
tached is 55mm. Take into consideration the minimum bending radius of the ca-
ble with the protective tube
SFPD-A10
attached.
<Reference>
Mount the emitter and the receiver at the same level and parallel to each other.
The effective aperture angle of the device is ±2.5° or less for a sensing range of 3m.
<Using beam adjustment mounting bracket MS-SFD-1-5 (Option)>
1.
Insert the mounting plate of the base bracket into the base bracket mounting rail
on the back of the device.

2.
With the base bracket in firm contact with the device, tighten the two ultra low-
head hex socket bolts [M5 (length 5mm), opposing faces 3mm] that fasten the
base bracket. Tighten to a torque of 3N·m or less.
No gap between base
bracket and device.

<Side mounting>
Loosen the two hexagon-socket head bolts with washers [M4 (length 8mm), op-
posing faces 3mm] and remove the bracket.
Change the orientation of the mounting bracket, and tighten the two hexa-
gon-socket head bolts with washers [M4 (length 8mm), opposing faces 3mm].
Tighten to a torque of 1.5N·m or less.
