4.2 Module features
4.2.1 Functions
Module supply
}The module supply provides the module with voltage.
Signals at the output
}“0” signal (0 V) at the output (O0+/O0-):
– Output is high impedance
– No current to the load
}“1” signal (+24 V) at the output (O0+/O0-):
– Output is low impedance
– Current is supplied to the load
Periphery supply
}The module routes the periphery supply from the module bus to the base module ter-
minals.
}The periphery supply is used to supply the outputs.
Input
}The input status is signalled to the head module via the module bus.
}The input has an input filter.

Function description
Operating Manual PSSu E F DI OZ 2(-T)(-R)
21328-EN-10 14
Output
}The head module sets the output status via the module bus.
}The max. capacity at an output depends on the load (see characteristic). Connecting a
higher capacity may lead to an error.
}Operation with electronic contactors has not been tested and may lead to errors.
Please contact our Customer Support team if you are using electronic contactors.
}Open circuit detection
}Cannot be used as a single-pole output
Test pulse output
}Test pulses can be switched on or off.
}Test pulses are switched on in the default setting.
}When test pulses are switched off, the periphery supply is constantly available at the
output.
Output test (not configurable)
}Outputs that are switched on are checked via regular off tests.
– Test pulses for outputs that are switched on: see technical details
– Outputs that are switched on are switched off for the duration of the test pulse.
– The load must not switch off because of the test.
}Outputs that are switched off are checked via regular on tests.
– Test pulses for outputs that are switched off: see technical details
– Outputs that are switched off are switched on for the duration of the test pulse.
– The load must not switch on because of the test.
Testing for shorts
}A test is regularly carried out to check for shorts between the outputs.
Open circuit detection
}The module will detect an open circuit between outputs O0+ and O0-.
}The result of open circuit detection is signalled to the head module via a virtual input.
The result is available within the user program:
– No open circuit detected: Status bit set
– Open circuit detected: Status bit not set
}Loads over 3kOhm may mistakenly be detected as an open circuit.

4.2.2 Integrated protection mechanisms
When the PSSuEFPS1(-T) or PSSu E F PS2(-T)(-R) is used to supply the system, the
module supply is buffered for 20ms if the supply voltage is interrupted.
The module has the following protection mechanisms:
}Cyclical output tests
}Tests for shorts across the output
}Test pulse signals are always buffered for 20ms.
The module provides the following diagnostic data:
}Start-up error
}Configuration error
}FS communication error
}Bus termination error
}Temperature error: too warm
}Temperature: too hot
}Output error
}Test pulse error
}Input error
4.2.3 Reaction times
Information on the reaction times of the inputs/outputs can be found in the "PSSuniversal"
System Description and the System Description "Automation system PSS 4000".

Functions for the FS outputs of a PSSu are defined in the PSSuniversal Configurator on the
PSSWIN-PRO system software:
}Read access through the standard bus system (configured per module):
“R” configuration
}Read/write access through the standard bus system (configured per output):
"&" configuration (local enable principle)
}Optimisation of ST process image by combining adjacent bits of the same type.

4.3.1.2 Input and test pulse output
Functions for the FS inputs of a PSSu are defined in the PSSuniversal Configurator on the
PSSWIN-PRO system software:
}Read access through the standard bus system (configured per module):
Configuration "R"
}Allocation of a test pulse to an input (configured per input):
}Optimisation of ST process image by combining adjacent bits of the same type.
Configuration „*“
INFORMATION
The PSSuniversal Configurator on the PSSWIN-PRO system software
must be used to define the I/O-Groups to which FS inputs and outputs be-
long (SafetyBUSp). The PSSu can be divided into sections A and B for this
purpose.
All the FS outputs on a PSSu always belong to section A.
All the FS inputs on a PSSu always belong to section B.
Section A and section B on a PSSu may belong to different I/O-Groups.
Further information on configuration is available in the PSSuniversal Configurator's online
help.
4.3.1.3 Addresses in the process image
The module occupies two consecutive bit addresses for the input in the FS-PII:
}Bit address 1: Input I0 for connecting the feedback loop (connection terminal).
}Bit address 2: Internal FS input I1 for transmitting open circuit detection (no connection
terminal!).
The module occupies one bit address for the output in the FS-PIO.
The display in the ST process image depends on the configuration. With read access ("R"),
the sequence in the ST-PII is:
}Bit address 1: FS output O0+
}Bit address 2: Input I0 for connecting the feedback loop
}Bit address 3: Internal FS input I1 for transmitting open circuit detection
With write access ("&"), the Bit in the ST-PIO is used to switch the FS output with the local
enable principle.

5.2 Installing the base module
Prerequisite:
}The head module must be installed.
}If the head module does not have an integrated power supply, a supply voltage module
must be installed to the right of the head module.
Please note:
}For mechanical reasons it is not possible to mix base modules with screw terminals and
base modules with cage clamp terminals.
}All contacts should be protected from contamination.
}The mechanics of the base modules are designed for 50 plug in/out cycles.
Procedure:
}We recommend that you wire up the base modules before inserting the electronic mod-
ules.
}Slot the groove on the base module on to the mounting rail from below [1].
}Push the base module back [2] until you hear it lock into position.
}On the mounting rail, slide the base module to the left until you hear the two lateral
mounting hooks on the adjacent module lock into position [3].
