Note
In the diagram above, the Inputs are wired to the internal power supply, available on the connector of the CCU
(+24VDC).The"Markinginprogress","Machineready"and"Fault"Outputsarewiredtoanexternalpower
supply.
 Description of the communication signals
• Startmarking(Input)
- Toactivatethe"Startmarking"Input,establishazeropotentialelectricalconnectionbetweenpins4and
5.
- Thisconnectionmustnotbeinferiorto500msnorsuperiortothecycletimeofthemarking󰘰le.
• Stopmarking(Input)
- Toactivatethe"Stopmarking"function,opentheelectricalconnectionbetweenpins5and9.
- This input does not guarantee immediate stoppage. A connector with 2 channels enables the achievement
ofasafetylevelPLd(optional)(ENISO13849-1:PerformanceLeveld).
- Safetymanagement:9connector(optional)
• Markinginprogress(Outputdrycontact)
- Theinformation"Markinginprogress"isavailablebetweenpins3and8.Itisprovidedbyapotential
free"dry"contact(relaycontact).
- ThissignalindicatesthattheCCUisperformingamarking.
Characteristics Maximum voltage

Status
Markinginprogress Depending on the mode selected
• Machineready(Outputdrycontact)
- The information "Machine ready" is available between pins 6 and 7. It is provided by a potential free "dry"
contact(relaycontact).
- ThissignalindicatesthattheCCUhasreceivedalltheinstructionsrequiredtoperformamarking.
Characteristics Maximum voltage

Note
The 7 pin is common to the "Fault" information and to "Machine ready". See: Connection diagram for the
dedicated Inputs / Outputs
