3.1 Safety-Relevant Symbols
3.2 Intended use
Devices in the SLP...-R series of safety light grids comprise a receiver unit and a corres-
ponding SLP...-T safety light barrier emitter. Together, this unit forms a multi-beam photo-
electric protective device. The protection beams are formed between the emitters and
receivers. This system may only be used as intended as an active opto-electronic protec-
tive device (AOPD) to protect danger spots and danger areas from being accessed.
If used for any other purpose, the intended function of the system can no longer be gua-
ranteed.
In addition to the notes in these instructions, the safety regulations, standards, and other
regulations concerning the application must be taken into consideration.
3.3 Application
Light grids from the SLP series can be used with 2-, 3-, and 4-beam access protections as
specified in EN ISO 13855. The beam spacings are fixed and meet the specifications out-
lined in the standard.
SLP light grids consist of an emitter and receiver.
The emitter and receiver for the SPL 8-2-A active column are incorporated into a single
housing. A deviation mirror SLP 8-2-M must be positioned on the opposite side to operate
the device.
A complete safety device includes a compatible control unit that controls the emitter, eva-
luates the receiver signals, and generates the resulting output signal (OSSD), as well as
an emitter and receiver.
Danger!
This symbol warns of an immediate and present danger.
Failure to observe this warning may result in personal injury or even death.
Warning!
This symbol warns of a potential fault or hazard.
Failure to observe this warning may result in personal injury or extensive damage to
property.
Caution!
This symbol warns of a potential fault.
Failure to observe this warning may result in the device and/or any systems and plants
connected to it malfunctioning or giving out completely.
Control units from the SB4... series can be used.

3.4 Mounting
There are grooves on the sides and back of the light grids for inserting M6 hexagon screws
to mount the devices. Make sure the devices are mounted such that they are not twisted.
A mounting set for securing and aligning the device is available as an accessory. Two
mounting sets are required for each profile.
3.5 Installation
The electrical connection for the profiles is established via the end cap with cable duct.
Refer to the connection diagrams for the terminal assignment.
Make sure that the connection cable to the SLP 8-2-A active column is safeguarded
against short circuits (for example, protected installation or cable with wires shielded from
one another) or that the emitter cable is laid separately.
3.6 Adjustment
The emitters generate visible red light. This ensures that the beam emitted can be easily
observed. When making adjustments, make sure that the emitter and receiver profiles are
installed vertically and that the axis of the first beam is positioned at the prescribed dis-
tance from the ground (EN ISO 13855).
The emitter profile must be aligned so that the light beams fall on the receiver profile. The
receiver profile must then be adjusted so that the indicators for the receiver channels light
up continuously. Check the control unit to see whether the relevant channel indicator is ac-
tive.
3.7 Indicators
The emitter profiles do not have any indicators. The red emitter beams indicate that the
emitter is ready.
A red standby indicator above the cable gland on the receiver profile lights up when the
power supply is connected. Each receiver in the profile is fitted with a red indicator that
shows the status of the receiver channel:
Table 3.1: Indicators
Warning!
The installation information included in the control unit operating instructions must
be taken into consideration.
On Light beam free,
reliable reception with double signal strength at least
Flashing Light beam free,
reception with single or double signal strength
Off Light beam interrupted or response threshold deceeded

4.1 Application
Deviation mirrors deflect the path of protection beams to offer protection on more than
one side using just a single emitter/receiver pair. Each mirror reduces the sensing range
by no more than 15 %.
The mirrors are arranged so that light beams from the emitter can be deflected to the re-
ceiver. To deflect the protection field through 90°, the mirror is positioned at an angle of
45°.
When aligning the layout, ensure that all components are arranged vertically and at the
same height. To roughly align the mirror, turn it so that you can see the profile of the re-
ceiver reflected in the mirror when looking at the mirror with the emitter behind you.
Aligning the mirrors is made easier by using the beam alignment aid.
It is important to ensure that the mirror surfaces are clean. Scratch-free cleaning agents
and lint-free cloths must be used for cleaning.

5 Signal lamps
Safety light grids from the SLP series with option L are ready for attaching signal lamps
that show the status of the safety equipment. The following color assignments are com-
monly used:
OSSD OFF red
OSSD ON green
Operational readiness yellow
Muting white
An SLP receiver with option L is suitable for up to three signal lamps, the active column
SLP8-2-A-L for four signal lamps.
The connection is made to the terminal compartment on the device (See Chapter 3.9)
5.1 Mounting
1. Turn the bayonet ring in the direction of the arrow (markings A and B must line up)
2. Attach the lamp module (markings A, B, and C must line up)
3. Turn the bayonet ring in the direction of the arrow (ring must engage)
Removal is performed in reverse order. Press down the bulb and turn counterclockwise to
remove from the bayonet holder. When mounting several lamps, observe the sequence
of the lamp modules.
5.2 Technical data
Light grids in the SLP series with option L correspond to basic devices in terms of their
technical properties without this option. The light grids in the SLP series are operated on
safety control units in the SafeBox SB4 series. Refer to the corresponding operating in-
structions for further details.

7 Testing and Application Checklist
The SLP light grids only become fully functional units when used in conjunction with Safe-
box SB4 control units. The information provided in the operating instructions for the SB4
applies in all cases.
Note: Observe the relevant laws and standards!
The relevant laws and standards that apply to the use of photoelectric protective
devices must be followed. There are differences depending on the area of use.
