backplane is used for communication between the head module and the electronic modules
and forms the carrier unit for the electronic modules. The terminal block is plugged into the
electronic modules and is used to connect the field wiring.
Details of the terminal blocks that can be used are available under "Intended Use".

4.2 Supply
}The module supply provides the module with voltage.
4.3 Integrated protection mechanisms
}The module has temperature monitoring.
The module provides the following diagnostic data:
}Start-up error
}Configuration error
}ST communication error
}Temperature error: too warm
}Temperature error: too hot
4.4 Outputs
The module has 4 relay outputs with a changeover contact.
Outputs
}The head module sets the output status via the module bus.
If the module does not receive a process image of outputs from the head module, then sub-
stitute values are used for the process data. The value that is to be used as the substitute
value can be configured.
Substitute values may be:
}Output switched off (default value)
}Output switched on

removed first.
}The mechanics of the electronic modules are designed for 20 plug in/out cycles.
}On electronic modules with outputs, the terminal block may only be inserted and re-
moved when the load is switched off. Unforeseeable error reactions may be triggered if
modules are inserted and removed under load.

module into the suspen-
sion lug on the back-
plane.

7 Wiring
7.1 General wiring guidelines
Please note:
}The actuators may be connected using unshielded cables.
}To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details).
}Use copper wiring.
7.1.1 Connection mechanism for terminal blocks
Procedure:
}Use a flat head screwdriver.
}Strip the wire back 9 mm.
}Feed the stripped cable as far as it will go into the opening for the spring-loaded ter-
minal.
}Check that the cable is firmly seated.
Please note:
}The minimum cable cross section for field connection terminals on the terminal blocks
is 0.15mm2 (AWG26).
}The maximum cable cross section for field connection terminals on the terminal blocks
is 1.5mm2 with ferrules (AWG14)
}Use copper wiring.

8 Operation
The status of the module is displayed via the "Module status display" and "Terminal status
display"; this is signalled to the head module and any error is entered in the head module's
diagnostic log.
8.1 Display elements and messages
Only the LEDs at the terminals 1, 3, 5, 7, 9, 11, 13, 15 are active. The terminal On.x2 lights
in switched-off state and terminal On.x4 lights in switched-on state.
