Correct installation method:
mounted on DIN track
1. Align the card slot at the bottom of the
main engine with the track. Push the main
engine in the direction of arrow 1 and tilt
it in the direction of arrow 2.
2. The way to remove the sensor is, Moving in the direction of the arrow
1 to promote the host at the same time, towards
the direction of the arrow 3 host to ascend.
Mounted to wall (for main module only)
Place the modules on the optional mounting
rack, install them together, and secure them
with two M3 screws.
Connect optical fiber module
1. Open the dust cover in the direction
shown by arrow 1.
2. According to the direction of the arrow
2 down fiber lock bar.
3. Insert the length of the fiber optic
module mark marked optical fiber.
4. Move the fiber lock rod down in the direction shown by arrow 4.
5. If you use a thinner fiber optic module, you need to use the adapter
that comes with it.
6. If the correct adapter is not connected, the thin fiber module will
not be able to detect the target
correctly. (Adapters are provided
with fiber optic modules. )
7. If the coaxial reflective fiber
module is connected to the
amplifier, the single-core fiber should be connected to the transmitter
side, and the multi-core fiber should be connected to the receiver side.
Product Function Setting
1. Quick threshold setting:
2. Manually adjust the threshold:
After the threshold is quickly set, you can manually press the +
and - keys to fine-tune the green threshold. The principle of threshold
fine-tuning is: No red value of product exposure < green setting value
< red value of product exposure;
It is recommended that the red value of the product be more
than 20 larger than the green threshold;
Note: When the red value is less than 100 in P--1 mode, it is
recommended to use P--2.
3. Normally open/closed switch:
In front of the

4. P1P2 mode:
P--1：The biggest test show 4095 Suggest have a difference of more
than 50 products red value;
P--2：The biggest test show 9999 Suggest have a difference of more
than 80 products red value;
5.Output mode:
TOFF (close delay) : Product without any delay, normal output;
S-D( one-time output): After induction, regardless of the detection time,
only output a set delay time width signal;
d-o( pull-up delay): Delay output, product induction, delay to the set
time before output, after the product left off output; (no output if the
induction time is less than the set delay time)
o-d( pull-down delay): Output delay, output the set delay time width
signal after the product induction leaves;
6. The light intensity
d--3,d--2,d--1 light intensity gradually decreased;
7. Detection mode:
