7.1 Pc-board MAPRO05
The pc-board MAPRO05 is responsible for the welding sequence and is managing the process control of the
S- and P-series. (MAPRO = MAster-PROcess)
Functions
– Logicfunctions of the welding process
– generating and monitoring supply voltages
– driving powerup-relais
– driving power unit/units
– monitoring control and operating elements (DS20BF, remote control, torch buttons)
– driving fans
– driving coolingpump
– monitoring flowmeter
– monitoring mains- and output voltage
– generating signal „welding current on“ (arc established)
– managing communications between PC and machine
– managing and storage of all welding parameters
– LorchNet communication (CAN-bus)
