2.2

Connection instructions for two parallel-connected welding
power sources and one PEK control box

1. Emergency stop coil

W01

, is connected together with the enclosed contact block,

which in turn has been fitted on

KM2

, in accordance with the diagram on page

14 (automatic welding machine) or page 15 (automation).

2. On the welding power source defined as Slave

CN18

(pin 1 and 2), on

AP1

, shall

be clamped for analogue control.

3. Start up both welding power sources and connect

ESAT

to the

Master

welding

power source.

4. Set parameter

762

to

1

, Master searches for the welding power source selected

as Slave.

5. Set parameter

767

to

10

, Node address on the welding power source selected

as Slave.

6. Move the

ESAT

connection to the welding power source defined as

Slave

.

7. Set parameter

10

to

16

, Slave function.

8. Set parameter

67

to

0

, with value 1 so the welding power source expects an

analogue signal.

9. Set parameter

712

to

0

, the wire feed is not controlled by the welding power

source defined as Slave.

10. Set parameter

713

to

0

, the travel motor is not controlled by the welding power

source defined as Slave.

11. Set parameter

762

to

0

, Slave does not search for another power source.

12. Set parameter

767

to

2

, Node address on the welding power source defined as

Master.

13. Set parameter

9000

to

10

, Node address for the welding power source defined

as Slave.

14. Switch off the voltage to both welding power sources.

15. Remove the clamp on

CN18

(pin 1 and 2) on the Slave welding power source.

16. Remove the clamp on

CN11

on the Master welding power source.

17. Connect cable

W02

to the welding power sources.

18. Switch on the voltage to the Slave welding power source.

19. Switch on the voltage to the Master welding power source.

20. Check that the emergency stop coil is working, both the welding power sources

(emergency stop relay/emergency stop contactors) are switched off. After
resetting, the welding power sources start up normally and are ready for use.

21. Check that the parallel current value can be set in

PEK

.

For more information on component location on the circuit board, see the service
manual for the LAF welding power source.
