}The periphery supply provides the outputs with voltage
4.3 Outputs
Signals at the output
}"0" signal (0V) at the output:
– Output is high impedance
– No current to the load
}"1" signal (+24V) at the output:
– Output is low impedance
– Current is supplied to the load
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:

6.2 Inserting and removing an electronic module
Please note:
}Backplane must be installed first.
}Electronic modules may only be plugged or unplugged if the terminal block has been
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.
6.2.1 Inserting an electronic module
1. Insert the electronic
module into the suspen-
sion lug on the back-
plane
2. Press the electronic
module downwards until
you hear it click into

7 Wiring
7.1 General wiring guidelines
Please note:
}The actuators may be connected using unshielded cables.
}The outputs do not need suppression for inductive loads.
}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).

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.

Green -- Module ready for operation
Green Green Module in operation and there
is a "1"-signal at the output

Periphery supply is missing/
temperature error: Too hot (1)
See module's dia-
gnostic log
(1) There are two levels of overtemperature.
}Too warm:
If the module temperature exceeds a threshold value, then:
– a warning is sent to the head module.
If the temperature drops back below the threshold value, the module sends an all-clear.
}Too hot:
If the module temperature exceeds another threshold value, then:
– an error message is sent to the head module
– the outputs are switched off
– The valid bits for the outputs are set to "0"
After the "too hot" message has been received, if the temperature drops back below the
"too warm" threshold value, the module will switch to an error-free state.
