It is used in a vertical or horizontal position, can be satisfied wherever hazardous points-of-
operation and danger areas require safeguarding.
The protector only protects the rectangular region of the light curtain. If it is installed not to be
correct, either operation is not according to the instruction manual and the correlation security
working rule, or the stamping equipments have faults, or other possible causes, it is unable to exert
the protective function.
Therefore, before installation and operation the protector, please read carefully and understand
fully related items in the instruction manual, in particular apprehend about the items stressed as
"Warning", "Attention" and so on.
In operating, please understand correctly and fully the operating performance about the protector,

Check and maintenance
Troubleshooting
The“control dependability”is main indicated that the design ,structure,and connection of the
equipment,system and interface should be fulled with that if the single fault in any of these parts
occurs, it shuld not hinder the implementation of the normal stop action, it should be to prevent the
start up of the follow-up action before troubleshooting.
S4 series incorporate dual-channel redundancy and self-diagnosis function.
This design complys with IEC/EN 61496-1 and IEC/pr EN 61496-2 standards and meets the
requirements for a Type 4 Active Optoelectronic Protective Device, the safest level for safety
products. A single fault or an accumulation of faults in the type 4 device should not lead to the loss of
the safety function.It will keep the safety function for ever.

Terminology
Emitter
The emitter consists of emitter units; it can emit the modulated light signal.
Sensor
The sensor consists of emitter units and (or) receiver units. It can emit and (or) accept the modulated
light and form light curtain with a reector (or through reector/mirror). Output a light passing signal
or light intercepting signal to controller. In order to be advantageous for the description, sometimes
also refers to the emitter and (or) the receiver.
Reector
The reector used to reect the modulated light from emitter units to receiver units.
Mirror
The mirror used to change the light direction of transmission from emitter units to receiver units, to
form multi-sides protection light curtain.
Signal cable
The signal cable used to connect the emitter, receiver and the controller, or connect the sensor and
controller.
Light curtain device
All the components that the sensor and the reflector of the reflection type, the emitter and the
receiver of the direct protection type and the reector, the emitter and the receiver of the multi-sides
protection type, produce the light curtain.
Light beam
The emitter unit sends out the infrared light, forms a bunch of parallel light after passing optics part.
Beam center line
It is the middle line of the light beam.
Light axis pitch
The distance of optical axis between the neighboring two bunches of light, uses to express the light
beam density of light curtain, the optical axis spacing is smaller, and the light beam is more crowded.
Detection precision
The light curtains' ability to detect the size of test piece, it means when the light curtain is shaded
anywhere, active opto-electronic protective device can have induction function and when the device
keeps off state, it needs the diameter value of the smallest test piece.
Protective range
The protector can protect length scope.
Light beam number
It is quantity of the light beams that sending out from emitter, the same as the quantity of the emitter
units in the emitter.
Light passing
It is the output state of the protector when the light curtain is not intercepted.
Light intercepting
It is the output state of the protector when the light curtain is intercepted.

Usage
The Photoelectric Protector is also named Safety Light Curtain, Safety Grating and so on. It is mainly
used for mechanical processing equipment, hazardous work areas, machinery and equipment to
prevent injury to the operator and caused injury or accident by into the dangerous region, to protect
personal safety.
The protector can achieve all trip protection for press which its slide could be stopped by brake at
any place in its slide’s trip, or can achieve protection of the trip between 30°~180° by using cam.
Using the protector in industrial manipulators, mould shapers, packaging equipments, automatic
equipments, jointing pipelining and other operating regions with danger, it can give an alarm after
entering the hazardous area or interlock with the safety system of the equipment, to protect personal
safety.

Specications Varieties, Application Wide
The protective height of conventional products
is from 113mm to 1493mm;
Pefect self-checking function
Ensure that the photoelectric protector don't
send the mistaken signal to the controlled
electrical equipment when it has faults.
The Self-locking Function
If preset the self-locking function, the press
slide stops moving after interception of light
curtain. But the press can not be restart, when
the light curtain is recovered to passing through
state. It shall be restart by pressing the reset
button.
Immunity
For the electromagnetism signal,the intense
lamplight,the welding and surrounding light
source has better immunity.
