Emergency Stop Signal For Power Source - Cebora PLASMA PROF 180 HQC Manual De Instrucciones

"V_Arc-NO-ISO" is the signal relating to the arc voltage at the power source output ("electrode-workpiece" voltage),
supplied directly and NOT insulated.
The "V_Arc-NO-ISO" signal is available with voltage values 0 ÷ 250 Vdc and with the positive terminal (workpiece po-
tential) electrically connected to the system earth potential.
The "electrode" potential is supplied with an approximately 10 Kohm resistor, fitted in line with the output.

"Emergency A" and "Emergency B" are the emergency stop signals supplied to the power source by the pantograph
control or by system protection devices. They must be supplied by a relay contact or safety device via two separate
contacts; triggering the device causes the contact to open and immediately shuts down the power source by opening
the line contact inside the power source. the power source therefore lacks power to the power circuits.
The "Emergency A" and "Emergency B" signals are active low (contact open): contact closure is required for the power
source to be ready for cutting. "Emergency A" or "Emergency B" signals immediately stop the current supply from
the generator.
The message Error 90 appears on the control panel (see error code table 4.2.5).
