3.1 Intended use
The module is suitable for use in safety and non-safety-related applications with
SafetyNETp.
The modules PSSu H FS2 SN SD and PSSu H FS2 SN SD-T may be used as a safety
components in accordance with the Lifts Directive 95/16/EC in accordance with the require-
ments of EN81-1/2:1998+A3:2009, EN81-20:2015, EN81-50:2015, EN81-22:2014 and
EN115-1:2008+A1:2010.
The programmable safety system should be installed in a protected environment that meets
at least the requirements of pollution degree 2. Example: Protected inside space or control
cabinet with protection class IP54 and corresponding air conditioning.
Intended use includes making the electrical installation EMC-compliant. Please refer to the

4.2 Supply voltage
4.2.1 Function description
The product provides the module supply and periphery supply for the modules on the mod-
ule bus:
}Module supply
Supply voltage for subsequent module (right-hand side)
}Periphery supply
Supply voltage for sensors, actuators and test pulses
The periphery supply is monitored for undervoltage and overvoltage. The periphery sup-
ply does not switch off automatically if levels drop below the limit values. However, the
red LED flashes and a message is entered in the diagnostic log.
– Monitored lower voltage value: 16V
– Monitored upper voltage value: 32V
The maximum time between two voltage measurements is 100ms.
The maximum time that can elapse between the first exceeding or falling below a voltage
value and the reaction of the head module is 100ms + cycle time of the FS module bus.
When the supply voltage is fed in separately, the module supply and periphery supply are
galvanically isolated. If galvanic isolation is not required, a common power supply may be
used for the periphery supply and module supply.

1005194-EN-02 | 12
4.2.2 Current load capacity
Ensure you comply with the current load capacity of the module and periphery supply (see
"Technical Details"). If the current load is higher, an additional supply voltage module is re-
quired to refresh the module supply and periphery supply.
}Module supply
The current load is the total current consumption of all the electronic and compact mod-
ules.
The module supply does not automatically switch off if values exceed or drop below their
limits. However, the "5 V" LED will light and a message will be entered in the diagnostic
list.
}Periphery supply
The current load is the total current consumption of the sensors, actuators and test
pulses supplied via the input/output modules.
The periphery supply does not automatically switch off if values exceed or drop below
their limits. However, the "24V" LED will light and a message will be entered in the dia-
gnostic list.
Please refer to the derating diagrams.

4.4 SafetyNET p
4.4.1 Connection to SafetyNET p
Functions
}The SafetyNETp interface enables I/Os to be controlled by means of a higher level con-
trol system (e.g. PSSu PLC).
}The head module receives signals from a higher level control system and forwards them
to the connected input/output modules.
}The head module receives signals from the connected input/output modules and forwards
them to a higher level control system.
}If a fault occurs, the module switches the connected failsafe outputs to a safe condition.
MAC address
}The MAC address is a factory-set default. It can found on the labelling strip on the front of
the module.
INFORMATION
Further information on SafetyNETp can be found in the "PSS4000 System
Description".
4.5 Decentralised inputs and outputs
The head module belongs to the performance class "Decentralised system PSSuI/O". It
enables the PSSuniversal to be used as a modular, decentralised input/output module:
}PSSu system without control functionality
}Electronic modules and/or compact modules must be added to the head module
}I/Os are controlled via SafetyNETp by means of a control system (e.g. PSSu PLC)

4.6 SD card
The SD card has the following functions:
}The SD card is used to store the naming data and the device project; see PSS4000 Sys-
tem Description.
}The SD card is part of the safety concept on PSS4000. If the SD card is missing or has
been swapped, the next time the PSSu system is booted it will be unable to achieve the
operating status "PSSu System in RUN condition without error". The SD card has a lock-
ing mechanism, which protects it from being removed from the card holder unintention-
ally. The SD card can also be sealed to protect it from manipulation, whether accidental
or intentional.
Sealing the SD card for additional protection:
NOTICE
Damage to files on the SD card
Files may be damaged if the card is removed from the device or the power
to the device is switched off as the SD card is being written.
Do not remove the SD card during operation and do not switch off the
power to the device while writing is in progress, otherwise files on the SD
card may be damaged.
4.7 Reset button
The "Reset" pushbutton on the head module has various functions:
}Perform a warm reset for the PSSu system.
The reset pushbutton can be used to perform a warm reset for the PSSu system.
}Transfer the naming data and/or device project from the SD card (deliberate operator ac-
tion to transfer the naming data and/or device project from the SD card to the device
memory).
INFORMATION
The warm reset and the transfer of the naming data and/or device project
are described in the "PSS4000 System Description". This is also where the
general effects on the PSSu system are described in detail.

7 Wiring
7.1 General wiring guidelines
Please note:
}The requirements of the supply voltages can be found in the chapter entitled "Technical
Details".
}Protective separation must be ensured for the external power supplies that generate the
supply voltages. Failure to do so could result in electric shock.
}The external power supplies for generating the supply voltages (periphery supply and
module supply) must meet the regulations for extra low voltages with protective electrical
separation (SELV, PELV). Failure to do so could result in electric shock. A device with a
basic insulation that has a supply voltage of over 50 V AC or 120 V DC must not be con-
nected in parallel to the module supply.
}The external power supplies must comply with the current applicable standard EN
60950-1, EN 61140, EN 50178 or EN 61558-1.
}The maximum current load for the periphery supply on the module bus is 10A. Please
refer to the derating diagram in the chapter entitled "Function Description".
}Earth the 0 V supply on the periphery supply or monitor each supply group for earth
faults.
}The connection of the 0 V supply to the central earth bar or earth fault monitor must be in
accordance with relevant national regulations (e.g. EN60204-1, NFPA 79:17-7, NEC:Art-
icle 250).
}Details of the minimum range for conductor cross sections on connection terminals can
be found in the section entitled "Technical Details".
}Use copper wiring.
