You can activate the automation N1 and the mode of functioning of the RI output in the menu: Configuration>Installation>General.
The choice of active level for DEFAULT signal is defined in the menu: Configuration>Installation>Default.
Automation cycle configuration
In the MIG menu, the specific auto "SETUP" page allows you to set:
•
Level of RI threshold (range: A) ;
•
Broken arc detection (range: s) ;
•
Delay before movement start (range: s) ;
•
Delay before movement stop (range: s) ;
•
Movement speed (range: cm/min).
The broken arc detection allows configuring the broken arc default.
The movement speed is a user information but it is not operated by the installation.
The other parameters are used to configure the RI output of the 3 following modes:
RI PROCESS
RI ARC (Fast RI)
MOUVEMENT COMMAND
Remark: The Output RI in the mode MOVEMENT COMMAND doesn't go under 1 if you decide to start welding again during the downslope phase.

2. timing after the movement stops

The relay RI closes 100 ms as soon as the current goes over the "RI threshold" defined in the SETUP.
The relay RI opens as soon as the current level goes under the "RI threshold"
Parameter: Detection level of the RI threshold
The relay RI closes 20 ms as soon as the current goes over 15 A.
The relay RI opens at the end of the welding as soon as the current level goes under 15 A.
The relay RI closes as soon as the striking and the timing defined in the SETUP are over.
The relay RI opens as soon as the timing after the downslope start is over.
Parameters: timing after start and timing after stop
