Part 3 Installation, Wiring and Commissioning
Notice
Before installing, please open the packing box and check the packing device according to the
packing list; When installing, turn off the power of the machine to avoid danger.
3.1 Determination of Installation Position
The installation position contains two elements of safety distance and high position.
In order to ensure the safety of the operator, the installation position of the safety light curtain must
conform to the requirements of safety distance and height, otherwise, there is still the possibility of
accidents.
3.1.1 Calculation of safety distance
lSafety distance is the minimum distance between the light curtain plane of a safety light curtain
and the cutting edge of a mold. The calculation method shall be determined according to the
braking mode of the pressure machine or with reference to the table below.

-12-
lFor a pressure machine in which the slider can stop at any position of the stroke, the safety
distance is calculated by formula (1).
Therein: S--Safety distance (mm);
K- The speed of a person's body or part near a dangerous area (mm /s);
T- Total braking time of the system (s);
C--Additional distance (mm);
lFor a pressure machine in which the slider can stop at any position of the stroke, the safety
distance is calculated by formula ( 2).
Therein: S--Safety distance (mm);
K- The speed of a person's body or part near a dangerous area (mm /s);
C--Additional distance (mm);
Ts- The time from the hand away from the light curtain to the slider of the pressure machine
reaching the bottom dead center (s). It can be calculated according to formula (3) or measured in
practice.
Determination of K value
lWhen the light curtain of safety light curtain is installed horizontally, the speed should be 1600
mm/s.
lWhen the light curtain of the safety light curtain is installed vertically, if the safety distance is
not more than 500 mm, the speed should be 2000 mm/s; If the safety distance is larger than 500
mm, the speed should be 1600 mm/s.
The determination of Tand Ts
lTotal braking time of the system T includes the response time of safety light curtain and
braking time of pressure machine.
lResponse time of safety light curtain is given by the supplier of safety light curtain.

-13-
lThe braking time of pressure machine should be measured according to the situations.
lThe calculation method of Ts is given in the following formula.
Therein: N- Number of engagement slots of clutch;
Tn- Time that the crankshaft rotates one cycle (S).
Determination of C value
lThe additional distance C is determined on the basis of the entry of hand into the light curtain
of safety light curtain (response area) without causing the response of safety light curtain.
lAccording to the detection accuracy of the safety light curtain, C value is selected according to
the rules of the following table when calculating the safety distance.
Detection accuracy (mm) Additional distance C(mm) Stroke start of safety light
curtain
≤14 0
Allowed>14-20 80
>20-30 130
>30-40 240 Not allowed
>40 850
Warning
The safety distance is one of the necessary conditions to ensure the protection function of the
safety light curtain. The safety distance must be calculated correctly and must be ensured
when installing!!
3.1.2 Determination of height position
Height position refers to the protection height of the safety light curtain relative to the upper and
lower position of the die of the machine tool. Namely under the premise of guaranteeing the safety
distance, the undermost light beam of safety light curtain should not be higher than the lower edge
of lower die and the uppermost light beam should not be lower than the upper edge of upper die, as

-14-
shown in Figure 3.1.1. This relates to the selection of protection height of safety light curtain.
The protection height should not be lower than that required light curtain protection height by
relevant safety standards.

(light curtain is a little lower, the hand can stretch into it upside the highest beam)
3.1.3 Settings for auxiliary protection measures
When the horizontal distance between the safety light curtain plane of the safety light curtain and
the front end of the die exceeds 400 mm, additional auxiliary photoelectric or protective bars should
be installed to prevent the operator from entering the inside of the light curtain plane, as shown in
Figure 3.1.5. When the distance is less than 400mm, Auxiliary photoelectric or protective fence and
other safety measures may be taken.
Fig.3.1.5 Incorrect installation position
( light curtain is too far from the die orifice, operators could enter danger zone )
Warning
A. The height position is one of the necessary conditions to ensure the protection function of
the safety light curtain. The installation must ensure that the height is in the correct position.
B. When the machine tool slides, we must overhaul the machine tool timely. Otherwise, even
if the safety light curtain is installed in the right position, it will not ensure safety.
C. If it is necessary to replace the mold in the use process, we must adjust the position of
safety light curtain according to the above two items of requirements.
D. The company is not liable for any personal injury caused by the wrong location of the
installation.
