1. Safety instructions
Please observe strictly!
ELEKTRONIK
All safety instructions are marked with this symbol and must be observed in particular.
Safe functionality of the entire installation is guaranteed only if this operating manual and applicable
accident-prevention regulations are observed.
Forming part of the controller's scope of delivery, this operating manual must be kept at the controller's
site of use.
All instructions in this operating manual must be strictly observed. The manual provides the user with important
information concerning proper use of the PLSGK safety controller. Before comisioning the …LVT/ …LCT… safety light
curtains with the PLSGK safety controller, make sure to read both operating manuals.
Observe applicable standards and guidelines when using safety light curtains. Local authorities or trade associations
will provide you with the relevant information. All other applicable regulations and standards issued by employers' liability
insurance associations must be observed too.
Qualified personnel Installation, commissioning and maintenance must only be carried out by qualified personnel.
Danger signs When operating a machine with …LVT/ …LCT… safety light curtains, ensure that nobody is located in the
danger zone. A danger sign to this effect must be affixed to the machine.
Light barriers do not provide any protection against flying objects produced through operation of the machine.
During a use of safety light curtains with an external controller or other secondary control units, operative or
organizational measures should ensure deactivation / testing at least once every 24 hours in order to detect and
subsequently eliminate any faults on the controllers.
Ensure daily inspection (after 24 hours at the latest):
Using the test rod*, interrupt the light barrier on the transmitting side from the start to the end of the protective field so that the
light field is only covered by this part. The green LED (or the yellow LED in the operating mode with restart interlock) must not
light up from start to finish.
* The test rod's diameter must correspond to the detection capacity indicated on the receiver's type plate.
When using BLVT / BLCT- blanking functions, make sure to observe the additional safety instructions and all other
specifications in the BLVT / BLCT operating manual.
When using cascaded light grids, make sure to observe the additional safety instructions and all other specifications in
the …LVTK / …LCTK operating manual.
Prerequisites for the use of safety light curtains:
- The safety distance between the protective field and
hazardous area must be large enough to ensure that,
during entry into the protective field, the hazardous points
cannot be reached before the hazardous movement is
interrupted or ended.
- Access to the hazardous area must only be possible
through the protective field (reaching under, over or around
the field must not be possible).
- Unintentional repetition of a hazardous movement must be
prevented by appropriate safety facilities.
- The safety category (type 4) of the accident-prevention
light curtain should be at least the same as the safety
category of the machine control unit.
- Acceptance test:
The acceptance test for the installation should be carried
out by competent personnel who are in possession of all

3.1 Muting Functions
PLSG1K / PLSG2K / PLSG3K
ELEKTRONIK
3.1.1 Muting (bypass)
Muting means brief bypass of a safety light barrier if this is required by the working cycle. For this purpose, +24V must be applied
to muting input pairs 1A - 2A or 2A - 1B or 1B - 2B. Muting is only permissible if the hazard zone remains inaccessible or no
hazardous movement is involved during the work cycle. This is ensured if material passes through the protective field of the
safety light grid so as to prevent access to the hazardous zone between the material and the safety light grid or preclude
hazardous movement. Applications include palleting machines, narrow-aisle storage facilities, forklift entrance routes, production
cells, bending presses, presses with material input etc.

3.1.2 Muting sensors
Differentiation between conveyed material) and humans or detection of non-hazardous movement is realized by at least 2
mutually independent muting sensors. These can comprise light barriers (for example, GR or MFL series from FiesslerElektronik), inductive sensors, cam switches or limit switches. The muting sensors must be conductive in the muted state.
Prevention of muting manipulation through proper assembly
The muting sensors must be installed so that the triggering sensor pairs 1A-2A , 2A-1B, 1B-2B cannot be interrupted
simultaneously by humans.

If necessary, the clearance H to
the passable area or the
distance S should be increased.
3.1.3 Muting time limit – monitoring of max. muting time
To prevent a safety light curtain from being continuously interrupted by intentional manipulation, a
dependable time monitor has been installed additionally. The maximum muting time on the PLSG1K has
been set firmly to 1 h. On the PLSG2K and -3K, the muting function is disabled after an adjustable time of
1 s to 253 s or 1 h. The default maximum muting time on the PLSG2K and PLSG3K is 30 s. The muting
time should be as short as permitted by the involved process (see Page 16). Furthermore, the muting
time limiter is able to check whether a muting sensor is mistakenly in the muted state. If the muting
function is interrupted due to time overflow, any new muting of the safety light barrier is only possible if all
muting sensors have returned into the non-muted condition. Important: If the function "Immediate end
of muting on clearing of the protective field" has been selected, there is no muting time limit.

Muting sensors
The muting time limit can be stopped, for
example, in case of material accumulation
via a machine contact which applies + 24
V to the TR input to prevent unwanted
deactivation of the PLSG outputs. Time
monitoring is resumed as soon as status
of a muting sensor changes.

3.1.4 Renewed muting state only after release of all muting sensors
Renewed muting of the safety light barrier is possible only if all muting sensors are in a non-muted state at the same time. If the
light curtain is interrupted after end of muting, e.g. due to expiry of the muting time limit, the outputs are deactivated. If the
protective field is clear again, the outputs are activated again either automatically or via the start button, in accordance with the
selected operating mode.

PLSG1K / PLSG2K / PLSG3K
ELEKTRONIK
3.1.5 Muting lamp
Muting (bypass) of the light grid is permitted only if this is indicated by a lamp. It lights up whenever the light grid is muted. 2
external muting lamps can be connected (24 V max. 0.5 A, min. 50 mA). If either the internal or the external muting lamp is
faulty or not connected, the other operational muting lamp indicates the muting state by flashing instead of shining
continuously. This draws attention to the incident. If no lamp functionality is available, the light barrier will not be muted.
Consequently, connection of an external muting lamp makes the muting function much more dependable.
3.1.6 Override after an unscheduled stop
This enables start after an unscheduled stop in the muted state. If the muting time elapses or the power supply is reset, the
output channels of the PLSGK are deactivated when the protective field is interrupted, even if a muting sensor pair of relevance
to muting is in the muted state. In this case, the outputs of the PLSGK can be reactivated again by pressing the start button, as
access to the hazardous area is blocked by the material in the protective area and the detection range of the muting sensors.
However, the outputs of the PLSGK will open again if the protective field is not cleared within a period of 35 s after pressing the
start button. Renewed muting of the safety light barrier is possible only if all muting sensors are in a non-muted state at the
same time. The override function is not available in the "cycle control" operating mode. The start / override button must be
installed so that it can only be activated from outside the hazardous area while leaving a clear view of this area.

As soon as the pallet interrupts the beams of both muting sensors located behind the safety light grid facing the hazard zone, the
safety light grid is bypassed. Once the pallet has moved on to a point where muting sensors is free again, the muting state persists
for a short, adjustable delay period, enabling the material to leave the range of the safety light grid without deactivation of the
PLSGK outputs. The setting of this termination delay period depends on the conveying speed and on the distance between the
safety light grid's protective field and muting sensor. The muting termination delay period on delivery is preset to 0 s (max. 30 s, or
195 s in conjunction with 3.1.10).
The muting termination delay period must be set as short as possible to guarantee soonest possible stop
of muting after the material has left the protective field.
This muting function is especially immune to manipulation, because the protective field must be infiltrated
before the muting sensors can be interrupted.
If the muting sensors are installed in front of the protective field outside the hazardous area, muting with a
termination delay period is not permitted.
3.1.10 Immediate end of muting when the protective field is clear again
No muting time limit
The muting state remains set only as long as it is absolutely required. The function "muting termination if protective field is cleared
again" stops muting of the safety light grid as soon as the protective field is cleared after passage of the material. A new muting
state is possible only after restoration of all muting sensors to the non-muted state. This makes it possible to detect a person
travelling on a floor conveyor if there is a gap between the conveyed material and the person.

Manipulation-proof muting if the material flow is only directed outwards from the hazard zone at extremely variable conveyor belt
speeds. This combined operating mode is intended for use at extremely variable material conveying speeds, if the material is only
transported outwards from the hazard zone. The muted state is terminated as soon as the material has passed the protective field.
This permits the muting termination delay to be set so as to maintain dependable muting even at very slow conveyor speeds and
prevent unprotected entry into the hazard zone immediately after passage of the material at high conveyance speeds. However,
this muting function cannot be used if the distance between the conveyed items is sometimes smaller than the distance between
the protective field and the muting sensor located furthest away inside the hazard zone.

3.2 Control and switching functions
PLSG1K / PLSG2K / PLSG3K
ELEKTRONIK
3.2.1 Two-stage deactivation of outputs (for control drives, e.g. robot safeguarding)
PLSG2K / PLSG3K
Output OSSD1 and OSSD3 open immediately, i.e. with the maximum reaction time of 3.5 ms. OSSD2 opens
with a delay of 0.5 s.
Output OSSD3 = category 3 in conjunction with OSSD1! Observe the safety notes in circuit diagram 5.
Possible application: If the hazardous movement is to be stopped in a controlled manner and the control device unit is not failsafe. For this purpose, the control is driven via OSSD1 and OSSD3. If the control does not stop a hazardous movement when
OSSD1 and OSSD3 are inactive, OSSD 2 disconnects the power supply and any open brake after 0.5 s, so that the hazardous
movement comes to an uncontrolled stop. In this case, the longer response time of 0.5 s must be considered when calculating
safety clearances to the hazardous area.
PLSG3K
3.2.2 Emergency-stop circuit monitoring (monitoring of guard doors and emergency-stop buttons)
One channel of a two-channel emergency-stop circuit with NC contacts can be connected each to muting sensor terminals 1A
and 2A. Pulsation of these circuits permits monitoring of cross-connections between the channels. If one channel is opened and
closed again, the PLSGK outputs are activated only if the other channel was interrupted simultaneously with the first channel. If
OSSD2 cut-off delay was also selected, output OSSD2 is deactivated with a delay even on actuation of the emergency-stop
function.
Not suitable for applications in which the emergency-stop function must be used to disconnect the machine's power supply.
3.2.3 Restart interlock (start of hazardous movement, enabled only via command initiation)
PLSG1K / PLSG2K / PLSG3K
The restart interlock prevents automatic release of the switching outputs after an interruption and reactivation of the protective
field (for example, on passage through the field). When the protective field is clear again, the PLSGK outputs are only
reactivated after the start button or two-hand button has been pressed and released.
The start button must be installed so that it can only be activated from outside the hazardous area while leaving a clear
view of this area.
PLSG2K / PLSG3K
3.2.4 Without restart interlock
Start of hazardous movement, enabled without command initiation.
After an interruption and re-activation of the protective field the PLSGK switching outputs are released immediately.
In this operating mode, it must not be possible to step behind the safety light grid (refer to Chapter 4.3 of the ULVT operating manual ).
PLSG3K
3.2.5 Two-hand start
Prevents inadvertent start of hazardous movement, e.g. in passable press areas.
In order to deliberately restart hazardous movement after an interruption of the protective field, there is the possibility of a twohand-start. For this, it is necessary to connect a NO contact of a button to muting sensor terminals 1A, and a NC contact of
another button to muting sensor terminals 2A. One exception is the operating mode: "Two-hand start with emergency circuit
monitoring". This operating mode requires the connection to be made at 1B, 2B instead of 1A, 2A. If the protective field is clear,
the PLSGK outputs can be enabled again if these two buttons are actuated simultaneously with a maximum tolerance of 0.5 s
and released. There is no limit on time offset during release.
The start buttons must be installed so that they can only be activated from outside the hazardous area while leaving a clear view of
this area.
3.2.6 Contactor and valve control (EDM) (control of subsequent switching elements)
PLSG1K / PLSG2K / PLSG3K
Switching elements connected downstream from the PLSGK (relays, contactors, valves) are checked for proper switching.
Before every release of a switching output, a check is made as to whether the connected switching elements are also released,
i.e. whether their force-guided auxiliary NC contacts are closed; only under these circumstances can the outputs be enabled
again. If the downstream switching devices are not activated within 750 ms after the outputs are enabled, the outputs are
disabled again and can be reactivated at the earliest after 1.3 s. This is to identify any defects on the cut-off elements before
they become hazardous (refer to connection diagram 1).
Always monitor the cut-off devices that directly disable hazardous movement, i.e. the last links of the chain.

ELEKTRONIK
3.3.1 Restart interlock only during hazardous movement
PLSG3K
Actuation of the start button is only necessary if the protective field has been interrupted during hazardous movement.
After an interruption of the protective field and its reactivation, the restart interlock is activated only if the switching elements
connected downstream from the PLSGK are active. If the downstream switching elements are inactive, i.e. no hazardous movement
is in progress, the PLSGK outputs are enabled immediately after an interruption and subsequent clearing of the protective field
without actuation of the start button. For this function, the downstream switching elements must be monitored by the valve and
contactor control (EDM). If there is a voltage of +24V at the EDM, i.e. the switching elements are inactive, the restart interlock is
deactivated. If the EDM is driven with +24 V for longer than 1h , the switching outputs of the PLSG are interrupted. If the protective
field is clear, the outputs can be enabled again by pushing the start button. In this case, the regular valve and contactor control
system is active. In the operating mode with external display, terminal MS1A+ indicates the protective field's status (conductive =
protective field clear) while terminal MS2A+ indicates the restart interlock's status (conductive = start button must be actuated). This
function cannot be combined with the emergency-stop circuit. Inputs MS1B and MS2B are available for muting.

Applications with cyclic infiltration of the protective field during non-hazardous movement or machine standstill can be ergonomically
safeguarded in this operating mode without a use of muting sensors.
In this operating mode, it must not be possible to step behind the safety light grid
(refer to Chapter installation conditions of the …LVT /…LCT oerating manual ).
3.3.2 Cyclic control (machine control defined by the operator's work patterns)
PLSG3K
The cycle mode enables an automatic restart of the machine after a predefined number of entries (cycles) into the protective field.
The maximum time period during which the cycles must be performed is monitored. You may enter 1 - 4 cycles and a monitoring
time of 30s or 120 s. According to the programmed number of cycles, the machine automatically performs one work cycle, and then
waits max. 30 or 120 s, according to the preset time, for the programmed number of cycles. If the time period is longer, the restart
interlock is activated. If during hazardous movement, the protective field is infiltrated, the PLSG outputs are disabled and the restart
interlock is activated. After a voltage reset, the restart interlock is activated too. The PLSG outputs can be closed again by
performing the preset number of entries into the protective field and subsequent activation of the start button (within the preset
monitoring time). The end of the work cycle is signalled to the machine by a machine contact that is connected at the cycle reset
input channel TR. If 0V is at the cycle reset input channel TR, i.e. the machine contact is open, the PLSGK outputs are interrupted
and the cycle counter as well as the time monitoring are reset. As long as the machine contact is open, entries into the protective
field are not counted for the start of the work cycle. If the machine contact closes again, therefore providing + 24 V to the cycle reset
input channel TR, time monitoring is started and all subsequent interruptions of the protective field are counted for the start of the
work cycle. Wiring diagram 10 shows this with an example of two-hand control.
In the operating mode with external display, terminal MS1A+ indicates the protective field's status (conductive = protective field
clear) while terminal MS2A+ indicates the restart interlock's status (conductive = start button must be actuated). This function
cannot be combined with the emergency-stop circuit. Inputs MS1B and MS2B are available for muting.
Neither muting time limitation nor override is possible in a combination of cycle control and muting.
Applications include insertion operations with work monitoring for control of press brakes with a table height of more than 750 mm or
revolving-transfer tables.
In this operating mode, it must not be possible to step behind the safety light grid (refer to Chapter installation conditions of the …LVT /
…LCT oerating manual )
This operating mode is permitted only when using hand or finger protection (light curtain's detection capacity <= 30 mm)

4. Setting of muting times
PLSG2K / PLSG3K
ELEKTRONIK
4.1 Setting and storage of muting time limits (max. muting time). Also refer to Chapter 3.1.3.
The operator can limiting the muting time on the PLSG2K & PLSG3K. The time period begins as soon as one muting sensor
switches into the muted state, and ends as soon as all sensors are in the non-muted state. This period should be set to the shortest
possible value permitted by the nature of the application, in order to maximize manipulation safety and optimize fault detection on
the muting sensors.
To ensure proper functionality of the system, however, the muting time limit should be sufficient to prevent the maximum muting
time from being exceeded given the slowest flow of material and the longest material items.
If the distance between the conveyed material items can be smaller than the distance between the muting sensors which are
remotest from each other (t 2), the muting time runs on until the gap between the material items is large enough again to disable all
muting sensors simultaneously (t 3). In this case, the muting time limit must be set such that it is longer by t2 than the time needed
between two larger gaps (t 1).

The delayed end of muting period starts as soon as the conveyed material has left the range of the muting sensors, so that they
no longer produce the muting state. The delayed end of muting period must be set to the shortest possible value to enable
cancellation of the muting state as soon as the conveyed material has left the protective field. However, this period should be
sufficiently long to cover the time needed for the material to be conveyed from clearing of the muting sensor located farthest from
the protective field until renewed clearing of the protective field at the slowest possible conveyor speed. If the conveying speed
varies very much, an operating mode comprising the combination "delayed end of muting period + end of muting as soon as the
protective field is free" should be selected.
The delayed end of muting period must be set to 0 seconds if the muting sensors are installed in front of the protective field outside the
hazard zone (refer to Chapters 3.1.9 and 3.1.11)
Delayed end of muting is set by actuating the start button according to the plain text
instructions output by the PLSG2K / 3K.
To change over between menus, briefly press the start button; to confirm the display, keep the
button held down until the "release button" prompt appears.
Example: The end of muting delay is to be lengthened from 0s to 20s:
1.
Turn off the supply voltage.
2.
Press the start button.
3.
Keep the start button pressed. Turn on the supply voltage.
4.
Keep the start button pressed. Plain text display: "TEACH TIME".
5.

6.
Release the start button.
7.

By default, the PLSGK
has the delayed end of

1 After deactivation of the muting sensors, the muted state persists until the muting termination delay is over.
2 rrespective of the muting sensors' states, the muted state is ended as soon as the xLVT releases its OSSDs again; renewed muting is only
possible once all muting sensors have been deactivated.
3 OSSD2 cuts out with a delay of approximately 0.5 s.
4 A two-channel emergency-stop circuit with a normally closed function is monitored at 1A and 2A; 1B and 2B are available for connecting 2
muting sensors.
5 If the restart interlock is active, the OSSDs can only be released again through simultaneous actuation of a NO contact at 1A and a NC contact
at 2A.
6 The muting time limiter sets the muting time to an adjustable value between 1 s and 253 s, or to a value of 1 hour.

1 After deactivation of one or more sensors required for invoking the muted state, this state persists until the muting termination delay is
over.
2 Irrespective of the muting sensors' states, the muted state is ended as soon as the XLVT releases its OSSDs again; renewed muting is
only possible once all muting sensors have been deactivated.
3 OSSD2 cuts out with a delay of approximately 0.5 s.
4 A two-channel emergency-stop circuit with a normally closed function is monitored at 1A and 2A; 1B and 2B are available for connecting
muting sensors.
6 The muting time limiter sets the muting time to an adjustable value between 1 s and 253 s, or to a value of 1 hour.

1 A two-channel emergency-stop circuit with a normally closed function is monitored at 1A and 2A; 1B and 2B are available for connecting muting
sensors.
2 If the protective field is not interrupted over this period, the outputs can only be released if the field is interrupted the correct number of times
followed by actuation of the start button. The time between the individual interruptions and actuation of the start button must not exceed the
monitoring time.
3 Number of times the protective field is interrupted and cleared prior to release of the outputs.
5 Terminals 1A and 2A can be used for connecting external indicators of the protective field's state and starting units; refer to connection diagram 9.
6 The muting time limiter sets the muting time to an adjustable value between 1 s and 253 s, or to a value of 1 hour.

Switch S for cycle count reset. Use
double contacts wherever possible to
enhance contact reliability.
S
Example of 2-cycle control on a machine similar to a press brake:
After the safety device is started, the protective field must be infiltrated as many times as necessary for triggering a work movement, i.e. 2
operations (cycles) in this case (refer to 1). After subsequent actuation of the start button (2) with the protective field clear, the OSSDs close and
the machine movement is started (3).
At the end of the work movement, the cycle reset switch S opens and the OSSDs open too (4). As long as S remains open (at least 30 ms), any
intervention of the protective field (5) does not count as an operation for releasing the work movement. The 2 interventions (6) after the closing of
S make the OSSDs close again, therefore starting a new work movement (7).
If the protective field is interrupted during hazardous movement (8), the OSSDs open and the work movement is stopped. A new work movement
(12) is produced only after 2 more operational interruptions (9) and actuation of the start button (10).
