Notes
1. The maximum incident light intensity displayed depends on the selected response
time.
Response time
Incident light intensity
STD, H-SP, FAST
Max. 4,000
LONG
Max. 8,000
U-LG, HYPR
Max. 9,999
2. When the timer is used, set the timer time.

3. When setting the shift amount using the digit display, the setting range differs
depending on the response time, as shown in the table below

o clear the value, turn off the time period holding function. Turning off the power
switch also clears the value.
5. If you have selected limit teaching for the changed incident light intensity (Algo-
rithm setting =
), note that the shift direction of the threshold differs depending
on the combination of the sensing output status and the sensing output operation.

setting
Set the incident light intensity to the target value. When
you set the display adjustment while the incident light
intensity does not have enough margin, the display
shows a blinking

Display adjustment OFF
Set the display to 0. This redefines the initially
displayed value as zero.

setting
The interference prevention function is disabled.
Use up to 4 different emitting frequencies. A
maximum of 4 sensor heads can be cascaded
per frequency setting.
Set this to minimize the effect of ambient
environment.
When this setting is set, mutual interference

Threshold
value follow-
up cycle
The incident light intensity can be monitored for the
cycle (1 to 9,999s) specified, for example when varia-
tions in incident light intensity are expected. When the
threshold value follow-up cycle is set, the threshold
value is adjusted according to the shift based on the
incident light intensity detected. However, the threshold
value is not stored
Sensing
output
setting
Select whether the threshold value should be followed
when the output is OFF or when the output is ON.
Storage
cycle set-
ting
Select the cycle for storing threshold values in the non-
volatile memory. The valid range is 1 to 250 times
Algorithm
setting
When limit teaching is used, the threshold value
is modified by the shift amount. The direction
of the threshold shift differs depending on the
combination of the sensing output status and
the sensing output operation, see note
(Recommended when using thru-beam-type
fiber or specular reflective-type fiber)
When auto teaching is used, the threshold value
is followed up on the basis of each cycle. (Rec-
ommended when using reflective-type fiber)
Notes
The direction of the threshold shift differs depending on the combination of
the sensing output status and the sensing output operation.

Error codes and troubleshooting
The following error codes may appear in the digital display
Error
code
Description
Remedy
The non-volatile memory is broken or
reached the end of its working life.
Please contact our office.
Error writing on the non-volatile memory
Load of the sensing output is short-cir-
cuited causing an over-current to flow.
Check that all amplifiers are
firmly attached and that there
is no gap between amplifiers.
