IDEC SE1L Manual page 17

Highly Reflective Background
Highly reflective backgrounds may cause false detection
causing the SE1L to detect a longer distance than the
actual distance. If an operating environment with a highly
reflective background cannot be avoided, an additional
distance of 200 mm is needed when configuring protection
or warning zones.
Protection zone
Additional distance ∗
x When the background is highly reflective, the
detected distance may be longer than the actual
distance.
x When setting the protection zone, an additional
distance must be added.
x Avoid using a highly reflective background (such
as mirror, corner cube reflector, reflective safety
jacket, road reflector). Otherwise, false detection
may occur in the protection zone.
x Perform tests to make sure the area is properly
configured before operation.
x Failure to follow the above precautions may lead
to critical injury or death.
Limited Detection Capability Area
The limited detection capability area is the area between
the optical window and the beginning of the detection
zone. The area from the origin point of the SE1L to 87 mm
from the origin point is the limited detection capability area.
In this area, a low reflective object is difficult to detect.
Protection
area
x The user must perform a safety assessment for
the possibility of objects entering the limited
detection capability zone.

Wiring
x Make sure that power is disconnected or turned off
during wiring.
x Do not use cables that are longer than the length
described in the specification of the SE1L. If cables
longer than the length described in the specification are
used, the safety function may not operate correctly and
may cause critical injury or death.
x Make sure that the power supply is within 24V DC±10%.
When using a battery, make sure that the power voltage
is within 24V DC –30%/+20%. Excessive power may
damage the SE1L.
x Do not use cables longer than the length
described in the specification.
Note: For safety, turn off the power during wiring.
