Cut/Mark +24 Vdc = the Pantograph control signals to
the Power source to start “Cut/
Mark” mode.
3.2.3 Digital signals from power source to panto -
graph control.
WIRING A RELAY DIGITAL OUTLET
contact voltage 24 Vdc / 120 Vac;
contact current 1 Adc / 0.5 Aac max;

The “Arc Transfer” signal is active at top (contact closed).
The “Arc Transfer” signal remains active for the duration
of cutting, including break-through phase.

The “Power Source Ready” signal is active at top (contact
closed).
The “Power Source Ready” signal remains active for the
time the Power source is ready to cut. As soon as an er-
ror message appears on the Power source or the “Robot
Ready” signal is deactivated from the Pantograph control,
the “Power Source Ready” signal ceases being active.
This means that the “Power Source Ready” signal can
detect both Power source errors and Pantograph errors.

The “Process Active” signal is active at top (contact
closed).
When the Pantograph control initializes the digital “Start”
signal, the cutting process starts with gas preflow, fol -
lowed by the cutting operation and subsequently by gas
postflow.
From the start of gas preflow until the end of gas postflow,
the Power source initializes the “Process Active” signal.
The Power source is performing the process.

graph control.
