2 Safety
2.1 Intended use
The safety gate system is used for interlocking and guard locking swing gates and sliding
gates.
The safety gate system can be operated in two ways:
}Unlocking with condition
The safety gate system prevents the safety gate from being unlocked while there is any
hazard within the danger zone.
}Unlocking without condition
The operator can unlock the safety gate system at any time. After starting the unlock-
ing, the guard locking creates a stop command. The time required to unlock the inter-
locking guard has to be longer than the time required to stop the hazardous machine
function.
The hazardous machine function may only be executed under the following conditions:
}There is a high signal at safety outputs 12 and 22 and
}There is a low signal at safety outputs S31 (Lock/Unlock Request 1) and S41 (Lock/Un-
lock Request 2).
Safety inputs S31 and S41 (solenoid operation) may only be operated under the following
condition:
}Plant is in a safe condition
Make sure that this is the case with an AND operation in the safety system immediately
before the output is operated.
The safety switch meets the requirements in accordance with:
}EN 60947-5-3 with the actuator PSEN ml 1.1: PDDB
}EN 62061: SIL CL 3
}EN ISO 13849-1: PL e (Cat. 4 )
}ENISO14119: Coding level Low, type 4
The safety switch may only be used with the corresponding actuator PSEN ml 1.1.
The safety level PL e (Cat. 4 )/SIL CL 3 is only achieved if
}the safety outputs use 2-channel processing
}The solenoid has 2-channel operation via safe, tested outputs, suitable for PL e (Cat.
4)/SIL CL 3 applications.
With 1-channel operation of the safety inputs S31 (Lock/Unlock Request 1) and S41 (Lock/
Unlock Request 2) it is only possible to achieve safety level PLd(Cat.2)/SILCL2.
Foreseeable misuse
}Safety switches and actuators of the safety gate system PSEN ml s 1.1 must not be
used as mechanical limit stops
}Use of the PSEN ml s 1.1 under corrosive environmental conditions (cooling emulsions,
surface treatment, gases, …)

jury and death.
– You should prevent the interlocking and guard locking system from
being manipulated with an inappropriate actuator.
– Keep the substitute actuator in a safe place and protect it from unau-
thorised access.
– If substitute actuators are used, these must be installed as described
under Installation [ 35]
– If the original actuators are replaced with substitute actuators, the ori-
ginal actuators must be destroyed before disposal.
}Do not remove the connector's protective cap until you are just about to connect the
unit. This will prevent potential contamination.

4.1 Structure
The interlocking and guard locking system prevents the safety gates to the danger zone
from being opened while there is any hazard within the danger zone (machine movement,
voltage, ...).
The safety outputs may have a high or low signal, depending on the position of the actuator
and the signal path of safety inputs S31 and S41 (solenoid operation).
Safety switch
Actuator
Safety switch
Actuator
Gate open Gate closed
Safety outputs 12 and 22
Under these conditions there is a high signal at safety outputs 12 and 22:
}Actuator is detected and
}Guard locking pin has successfully been activated (guard locking pin is in the locked
position) and
}There is a high signal at the inputs S11 and S21
If one of these conditions is not met, the signal at the safety outputs will be low.
Feasibility monitoring for safety inputs S11 and S21
}If one safety input switches from high to low, while the other safety input remains high,
an unequal status is displayed: Input LED flashes yellow
}If this safety input switches back from low to high, while the other safety input remains
high, a feasibility error is displayed and a partial operation lock is triggered: Input LED
flashes yellow
A switch to a high signal will only lead to normal switch operation if both inputs had a low
signal. From this moment on, the switch to high may occur (partial operation lock see Error
display [ 56]).

}Diagnostic input Y1
If a fieldbus module of the SDD is used, the diagnostic input Y1 is automatically activ-
ated and data is read.
If no fieldbus module of the SDD is used, the diagnostic input Y1 is not used.
}Signal output/diagnostic output Y32
The status of the actuator is output. If a fieldbus module of the SDD is used, the signal
output/diagnostic output for the writing of data is activated.
4.2 Activation of safety inputs S31 and S41 (solenoid operation)
}If there is a low signal at safety inputs S31 and S41, the guard locking pin does not
change its position.
}Guard locking may only be deactivated once the hazardous movement has been com-
pleted.
Active use of Safety Device Diagnostics
}The safety inputs S31 and S41 have a high signal within max. 500 ms after the receipt
of the guard locking activation.
Single connection
Guard locking is activated through a high signal (length 350 - 400 ms ) at inputs S31 and
S41 (solenoid operation). After activation, the inputs must be low. Another pulse (length
350 - 400 ms ) at these inputs deactivates guard locking.
Series connection
In a series connection with n safety switches the safety lock is activated by a high signal
with a minimum length of t=n*(350 - 400 ms) at the inputs S31 and S41 (solenoid opera-
tion).
Number of safety switches in

4.3 Safety Device Diagnostics
Safety Device Diagnostics is an option that can be selected independently of the safety-re-
lated wiring.
When using the Safety Device Diagnostics, up to 16 sensors connected in series can be
connected as a subscriber to a fieldbus module.
The communication of the sensors with the fieldbus module is automatically built up again
with each new supply of the supply voltage. As a result, a sensor can be exchanged, e.g.
when servicing, without the need for special measures.
An exchange can be detected via the fieldbus module e.g. through the serial number.
}With Safety Device Diagnostics there are the following diagnostic options for the field-
bus module:
– Poll information of the sensors (examples: what sensor in the series has switched,
at what point could there be an open circuit in the series connection)
– Read configuration parameters of the sensor (examples: Number of teach-in pro-
cesses remaining, serial number of the switch)
– Perform actions (example: poll updated actuator name)
– Selectively activate or deactivate guard locking of individual PSEN ml within a
series connection
The results of the sensor diagnostics can be checked already during the installation phase
via the display in the fieldbus module, without the need to connect the fieldbus module to
the network.
}With Safety Device Diagnostics there are the following diagnostic options for the field-
bus module for simple wiring:
– Information is passed on via the fieldbus module directly to the network
– Mappings of the signal outputs to the sensor are automated by the SDD.
This prevents wiring errors and an expansion or reduction of the sensors is possible
without the need to change existing wiring.
– Wiring in accordance with IP20: Rapid installation in the control cabined is enabled.
– Wiring in accordance with IP67: Various passive junctions can be used (see Order
references for accessories [ 71]) to connect several sensors with only one
cable from the field in the control cabinet.
Further information on Safety Device Diagnostics can be found in Additional documents
that apply [ 8].
4.4 Operating modes
The safety switch can be used in various operating modes.
}Operation without safety device diagnostics
– Standard operating mode
After every restart the safety switch is in operation without Safety Device Dia-
gnostics.
– No communication with Safety Device Diagnostics
Function description
Operating Manual PSEN ml s 1.1
1004670-EN-01 16
– Activating/deactivating the guard locking is only via the signals S31 and S41
}Operation with passive use of the Safety Device Diagnostics
– Safety switch supplies diagnostic data to Safety Device Diagnostics
– Activating/deactivating the guard locking is only via the signals S31 and S41
}Operation with active use of the Safety Device Diagnostics
– Activate/deactivate the guard locking by a combination of a Safety Device Dia-
gnostics command and the status of the safety inputs S31 and S41 (S31 and S41
must have a high signal).
The safety requirements are guaranteed by the signals S31 and S41 (the fieldbus
for Safety Device Diagnostics communication is not safe).
}Operation with specification of direction when activating/deactivating he guard locking
A specification of direction can be used to control the change of the guard locking
status.
– Toggling: The safety switch changes with each simultaneous controlling of S31 and
S41 the guard locking status (activated <-> deactivated).
– Force Direction: The safety switch is selectively activated or deactivated by offset
activation of the rising edges of S31 and S41.

6.1 Important information
Make sure that the selected evaluation device has the following properties:
}2-channel with feasibility monitoring
Both OSSDs must change switch state synchronously. In particular, the evaluation
device must monitor that the state of both OSSDs was "Gate unlocked" before both re-
turn to the "Gate locked" state and vice-versa.
}OSSD signals are evaluated through 2 channels
}The state of the OSSDs must be tested before and after safety inputs S31 and S41 are
activated (solenoid operation) (see Timing diagram [ 17])
WARNING!
Potential loss of safety function due to failure to test for a safe condition
Depending on the application, serious injury or death may result.
– Use an evaluation device/safety system to test whether the plant is in
a safe condition.
– Do not operate the solenoid of the PSEN ml s 1.1 via S31/S41 unless
the plant is in a safe condition.
}The use of Safety Device Diagnostics is described in the System Description "Safety
Device Diagnostics".

6.4 Series connection
CAUTION!
Extension of delay-on de-energisation
When several (n) devices are connected in series, the delay-on de-ener-
gisation time adds with the number of interconnected safety switches.
The max. delay-on de-energisation is made up of the
risk time (see Technical details [ 65])
+ (n-1) x max. delay-on de-energisation of the inputs
+ max. delay-on de-energisation of the evaluation device
The safety switches PSEN ml s 1.1 are suitable for series connection with max. 16 safety
switches.
In practice, the maximum possible number will be limited by the following parameters,
among others:
}The required SIL level (e.g. SIL CL 3),
}the required performance level (e.g. PL e (Cat. 4)),
}the maximum delay or risk time permitted by the application,
}Cable length (see notes on cable lengths),
}Height of supply voltage.
Ensure there is sufficient supply voltage, taking inrush currents and fusing into considera-
tion.
Notes on cable lengths
}Determine the values under the following conditions:
Room temperature (25°C), conductor cross section 0.25mm2, output load per output
(12,22,Y32) each ≤10mA

Checks and maintenance
Operating Manual PSEN ml s 1.1
1004670-EN-01 57
11 Checks and maintenance
Regular inspection of the switch function is required to guarantee the trouble-free, long-
term function.
If the interlock and guard locking system is only used rarely (opening and closing the safety
gate and activating/deactivating the guard locking device), a manual function test is re-
quired.
The correct function of the device should be checked at regular intervals and after each er-
ror.
Test intervals in accordance with EN ISO 14119:
}for SIL CL 3/PL e at least 1x per month
}for SIL CL 2/PL d at least 1x per year
The Appendix contains a Check list [ 75], which should help you perform the test.
Visual inspection:
}Check that the seal on the security screw on the auxiliary release is intact. If the seal is
not intact, make sure that the security screw is inserted and use varnish to seal the se-
curity screw.
}Check the safety switch and actuator for damage.
}Make sure that the safety switch and actuator are firmly secured.
}Check the offset of the safety switch and actuator.
– Max. lateral offset
– Max. angular offset
– Max. vertical offset
}Check that the wiring is correct.
}Remove any dirt from the safety switch and actuator.
Function test
}The actuator is detected and at the safety outputs 12 and 22 there is a high signal after
detection of the actuator.
}The guard locking device can be activated/deactivated when the safety inputs S31 and
S41 are activated.
}Under these conditions there is a high signal at safety outputs 12 and 22:
– Actuator is detected and
– Guard locking pin has successfully been activated (guard locking pin is in the
locked position) and
– There is a high signal at the inputs S11 and S21
If one of these conditions is not met, the signal at the safety outputs will be low.
Escape release
}Test whether the button of the escape release pin can be detected and reached.
}Check the function of the escape release.
