1.1 Validity of documentation
This documentation is valid for the product PSSu E S 4DI-D. It is valid until new document-
ation is published.
This operating manual explains the function and operation, describes the installation and
provides guidelines on how to connect the product.
1.1.1 Retaining the documentation
This documentation is intended for instruction and should be retained for future reference.
1.1.2 Terminology: System environment A and B
The PSSu system can be used in two different system environments. The module's applic-
ation area is described in the chapter "Intended Use" of the manual.
The distinction is made between

4.3 Configuration
4.3.1 PSSu assignment in system environment A
It is not necessary to configure ST inputs in the PSSuniversal Configurator on the
PSSWIN-PRO system software, but ST modules can be selected and displayed.
The ST process image can be optimised by combining adjacent bits of the same type into
bytes.
If the status byte is configured, the ST process image cannot be optimised.
Further information on configuration is available in the PSSuniversal Configurator's online
help.
4.3.1.1 Addresses in the process image
The module occupies 4 consecutive bit addresses in the process image.

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].

5.3 Inserting and removing an electronic module
Please note:
}Only insert on to base modules that are already installed.
}Preferably these base modules should be ready wired.
}Electronic modules with outputs may only be inserted and removed when the load is
switched off. Unforeseeable error reactions may be triggered if modules are inserted and
removed under load.
}When an electronic module is plugged into a base module for the first time, one part of
the coding element remains on the electronic module, while its counterpart is fixed on to
the base module. This is how the base module is coded.
}The mechanics of the electronic modules are designed for 50 plug in/out cycles.

5.3.3 Changing an electronic module during operation
It is possible to change an electronic module during operation. The configuration data is re-
tained when a module is changed.
Effects:
}System environment A:
– In the event of a potential FS communication error, the FS section of the PSSu sys-
tem and all relevant I/O-Groups (SafetyBUS p) switch to a STOP condition.
}System environment B:
– All FS hardware outputs on the PSSu system switch to a safe condition.
– The substitute values are used for the modules' FS outputs, with Valid Bits = FALSE.
CAUTION!
Sparking can cause interference and errors!
Only change the module when the load is switched off!
