1. MC light curtain is mainly used for mechanical processing equipment,
hazardous work places , machinery and equipment to prevent injury to the
operator and suffering injury or accident by into the dangerous region, to
protect personal safety.
2. MC light curtain is to be used alone or matching with safety
modules,such as the safety relay,emergency stop switch etc. to form
more complex control system for the alarm intruding into the dangerous
areas or equipments protection system interlock.

6. Controller Specification
There are 4 kinds of controller as below for your options
SR4P2A1B24N 、SR4P2A1B24P 、SR4P3A1B24 、ND controller,the
detailed usage and wiring in the corresponding instruction manual.
Please contact us for more information.
7. Peripheral Reflecting Surface Influence
If it has the smooth reflecting surface around the light curtain, like the
metal plate, the floor, the ceiling, the work piece, the cover, the partition
board, the glass plate and so on, the protector placement position must
be away from the reflecting surface farther than value
A
(m), value
A
can
be calculated by the formula in form, or be consulted from the
coordinates chart
The placement position schematic drawing of prevented the influence
from the reflecting surface around the light curtain
5
A. The smooth reflecting surface around the light curtain, can cause the
protector to lose the normal function, further to lose the protective
function.
B. The placement position of the protector, must be as far as possible
away from the reflecting object, or cover up the reflecting object,
eliminates the disturbance around the light curtain, guarantee the
security .

9. Debugging
Should do check carefully the same after finishing wiring to ensure of
correct connection. Don't provide power till everything is going well.
1. Debugging
①check power supply
To ensure the voltage same as that
marked,tolerance: ± 15%
②power on
To connect as per instruction and check carefully before
power on
③alignment
Adjust sensor's position and angle to make green light
off and red light on
④test
To interrupt each beam in turn to ensure device runs
well,
Light interrupting,red light on,green light off
Light passing:red light off,green light on
⑤mounting position
To ensure of the light curtain being active.
⑥fix the bracket
Fasten the crew to keep stable.
⑦test end
