Page 9: Description Of Operation
DC supplies The diodes D13 - D16 rectify the 42 V AC supply. The rectified voltage is used to power the wire feed motor(s). It also powers the switched voltage regulator. 0740 800 202 - 9 - © ESAB AB 2018... -
Page 10: 13Ap1:2A Start / Stop
The Start and Stop commands come from the robot, via the CAN bus. Terminals E1 and E2 are intended for Start / Stop signal from a manual welding torch, this is not used by the FeedControl. 0740 800 202 - 10 - © ESAB AB 2018... -

Page 20: Fault Codes
The wire feed speed differs from the set value by more than 1.5 m/min for more than 3 seconds. This fault stops the wire feed. After a period of 5 seconds, restart is permitted. 0740 800 202 - 20 - © ESAB AB 2018... - Page 21 Stack overflow The program execution does not work. This fault should never occur in reality: the fault code is intended as an aid during development work. Contact ESAB if the fault does occur. No gas flow Gas flow is too low.

Page 22: Service Instructions
Overall, handling of ESD-sensitive devices should be minimized to prevent damage. Service aid ESAB can offer a number of service tools that will simplify the service. Antistatic service kit Ordering no. 0740 511 001 The kit makes it easier to protect sensitive components from electrostatic discharge. -

The software update is made from a PC, it has to be managed by a trained serviceman. For this a PC program called ESAT, ESAB Software Administration Tool, is needed. The PC is connected to the welding equipment by a cable connector and a CAN reader. From the ESAT it is possible to update the software. -
