3.3 For your safety
WARNING!
Potential loss of safety function during adjustment and repair work!
When carrying out adjustment and repair work, make sure that the power
supply of the plant is switched off and protected against switching on again.
WARNING!
Loss of safety function due to manipulative use of substitute actuating elements!
When substitute actuating elements are used, these have to be installed as
described in chapter Initial installation of safety switch [ 31]. When substitute actuating elements are used in a manipulative way to defeat the protective device, operating the plant presents a threat to life.
The operator has to consider this in the hazard analysis and he must determine possible countermeasures.

4 Function description
The interlocking and guard locking system prevents the safety gates to the danger zone
from opening while the hazardous machine is switched on.
There is a high signal (safety gate closed and locked) at safety outputs X1-3 and X1-4 if the
following conditions are met simultaneously:
} Inputs X2-3 and X2-4 are high and
} The bolt tongue is within the response range and
} The guard locking element is engaged in the bolt tongue and
} The escape or auxiliary release pin is in the correct position.
Signal output X1-9 is high if:
} The bolt tongue is within the response rang
There is a low signal (safety gate open and hazardous machine function interlocked) at
safety outputs X1-3 and X1-4 if the following occurs:
} Inputs X2-3 or X2-4 are low or
} The guard locking element is outside the bolt tongue or
} The escape or auxiliary release has been operated or
} The guard locking element is not engaged in the bolt tongue.
If the safety outputs have been shut down by either of the inputs X2-3 or X2-4, they cannot
be switched back on until both inputs are low simultaneously.
To operate the solenoid, a high signal must be present at X1-6 (X2-6) and at X1-7 (X2-7)
after the hazardous movement has been ended.
4.1 Normal /Unlock mode
Normal mode:
The safety gate to the danger zone is not unlocked until the hazardous machine is stopped
and the pushbutton for access request has been operated.
} The guard locking element is disengaged from the bolt tongue as soon as there is a
high signal at terminals X1-6 and X1-7 or X2-6 and X2-7, followed by operation of the
pushbutton for access request.
Unlock mode:
The safety gate to the danger zone is unlocked when the hazardous machine is stopped.
This enables easier access for cleaning staff once the shift has ended, for example.
} The guard locking element is disengaged from the bolt tongue as soon as there is a
high signal at terminals X1-6 and X1-7 or X2-6 and X2-7.

5.1 Notes on cable run
The maximum cable run depends on the voltage drop in the supply voltage conductors for
solenoid operation. The level of voltage drop is determined by the
} cable resistance of the cables
} solenoid current of the solenoid
If the voltage drop in the supply voltage conductors becomes too high, the voltage for
solenoid operation can permanently be set to the upper tolerance range (see Technical details).
The max. cable diameter is 10 mm.
Example:
} Connecting 3 safety switches in series
} Total cable run: 25 m
} Conductor cross section: 0.5 mm
2
} Solenoid current per solenoid: 1.5 A
} Voltage for solenoid operation: 24 V

U~0.05*10*1.5*4.5~3.4 V U~0.05*5*1.5*3~1.1 V U~0.05*10*1.5*1.5~1.5 V
U~cable specific impedence*cable length*cable factor*current
Cable impedence(2x0.25 mm²)
=0.05 Ohm/meter

The voltage drop over all the safety switches is 6 V. This means, there are only 18.0 V at
the terminals of the last solenoid. The solenoid is no longer operated reliably. If the voltage
for operating the solenoid is increased by the max. permitted tolerance to 26.4, there are
still 20.4 V at the terminals of the last solenoid. The solenoid switches reliably.
Wiring
Operating Manual PSEN sg2c

5.2 Recommended cable cross sections
The values in the table are valid for a series connection with max. 3 sensors and a voltage
for solenoid operation of 24 V. The solenoid current is 1.5 A per solenoid.
For differing values the conductor cross section must be calculated.

50 0.5 mm2, AWG21 x x
60 0.5 mm2, AWG21 x x
70 x x x
Cable runs marked with an x are not recommended.
For operating several safety switches with greater cable runs, the cables for solenoid operation (terminals X1-6 and X1-7) have to be carried individually, or several cables have to be
used. If more than three safety switches are connected in series or cable runs over 60 m
are required, please contact Pilz.
The permitted conductor cross section is at least 0.25 mm². To have a higher conductor
cross section, two cable cores can be inserted into a terminal. This adds together the conductor cross sections and halves the cable resistances. In this case, use a terminal lug! The
signals important for cable resistance are:
} 24 V (X1-1 or X2-1)
} 0 V (X1-2 or X2-2)
} the two solenoid operation signals (X1-6 and X1-7 or X2-6 and X2-7).
5.3 General wiring guidelines
Please note:
} All metallic surfaces on the safety switch are connected to 0 V via a resistor (100
kOhm) for functional earthing.
} UL requirements:
– Use copper wiring with a temperature stability of 75 °C.
– Use an LVLC supply (LVLC: limited voltage, limited current).
– Use multicore cable with a cable diameter of 6 ... 10 mm.
} When 2 cables are used, make sure that both cables have the same cable diameter,
otherwise the strain relief will fail.

} The permitted conductor cross section for the connectors is 0.25 - 1.0 mm², 23 - 17
AWG.
} When calculating the max. cable run, remember to take into account the chapter "Notes
on cable run".

5.6 E-STOP pushbutton connection
CAUTION!
With versions with integral E-STOP pushbutton, the E-STOP pushbutton
(terminals X1-10 to X1-13) must be integrated into the plant/machine's ESTOP concept in accordance with EN/IEC 60204.
5.7 Enabling switch connection
Details of the pin assignment of the female 5-pin M12 connector for the enabling switch can
be found in the block diagram and the terminal configuration.
We recommend you use the PIT en1.0p-5m-s (order no. 401 110) as the enabling switch.
5.8 EMC requirements
Please note:
} The power supply must meet the regulations for extra low voltages with protective sep-
aration (SELV, PELV).
} The inputs and outputs of the safety switch must have a protective separation to
voltages over 60 V AC.
} The supply voltage has to be at the safety switch terminals within the indicated toler-
ances (see Technical details).
} the supply voltage of the safety switch must be secured with a fuse of type quick
between 2 A and 10 A.
} The electrical installation must be performed in accordance with IEC/EN 60204.
} The assured release distance (SaO) can be influenced by external influences (e.g.: tem-
perature, dirt, EMC) (see Technical details).
INFORMATION
Safety relays with a wide-range power supply or in AC device versions have
internal potential isolation and are not suitable as evaluation devices. Only
safety relays with a 24 VDC supply voltage are suitable.

INFORMATION
When the solenoid is operated in single-channel, only a safety level of PL d
(Cat.2)/SILCL2 can be achieved.
To achieve PLe(Cat.4/SILCL3, the solenoid must have dual-channel operation, e. g. via safe pulsed semiconductor outputs with high current load
capacity (0.9 A for 50 ms).
