Digital output signals (signals to robot)
General
NOTE!
If the connection between the power source and the ROB TSt interface goes
down, all digital and analogue output signals on the robot interface will be set
to "0".
The power source supply voltage (24 V SECONDARY) is available in the ROB TSt
interface.
24 V SECONDARY is electrically isolated from the LocalNet. A protective circuit
limits excess voltages to 100 V.
Use pin X14/1 to select which voltage is to be connected to the digital outputs of
the ROB TSt interface:
-
-
Power source
Pin X2/14
ready
Pin X7/2 or X12/2 or X5/10
The "Power source ready" signal remains on for as long as the power source is
ready for operation.
The "Power source ready" signal drops out when a fault occurs on the power
source.
Process active
The "Process active" signal remains on for as long as the power source is in use.
In other words, an open circuit voltage or welding current is present on the cur-
rent sockets.
Current flow
The "Current flow" signal is set when the welding current is 10 A or higher.

Robot control external voltage (24 V):
Connect the external voltage of the robot control digital output card (PLC)
to pin X14/1
Power source supply voltage (24 V SECONDARY):
Place a jumper between X14/1 and X14/7
