Parameters can be modified during operation and will immediately affect the output
signals! Device will automatically save the last settings.
During the plasma cutter’s operation, the current arc voltage is shown on the display.
If there are no arc voltage present, display shows - - -.
Reference voltage (Ref) can be set by pushing V (left) or ꓥ (right) button. (During operation
the green (OK) led flashes when reference voltage is setting). User can set Ref from 45 V
to 265 V. Factory setting 180 V.
To enter a setup menu press and hold • (middle) button for one sec. The LED display will
start flashing then the setup menu will appear.
Select the parameter by pressing • button. Press V / ꓥ button to modify parameter’s value.
Sdt - Set delay time from 0.1 to 9.9 sec. Time between Arc OK signal appears and
generation of signals up and down is enabled. Factory setting 0.5 s.
HYS - Hysteresis from 2V to 32 V (2 V step). Voltage frame around reference. If arc
voltage is higher than Ref + HYS/2 then down signal is generated. If voltage is lower than
Ref - HYS/2, up signal is generated (see the output signal example below). Factory setting
6 V.
AdL - Ant-dive limit from 50 V to 300 V. Arc voltage that disables THC. If voltage goes
higher than Anti-dive limit all output signals go low. The parameter’s value must be set
higher than reference voltage. Factory setting 220 V.
tSt - Test mode. Only available when no arc voltage present! Pressing V or ꓥ button
generate output signals. The display indicates direction.
To leave a setup menu, do not press any button for around 2 seconds.
In case of communication failure E-I is shown on the display. Please check the optical
cable is properly inserted on both sides and that the PlasmaSens sensor device is turned
on.
