CDM 3201 Order No. BA 92-12-3321A Issue 19.09.08 45
5.7.3 Charging Monitoring (Ready)
A charging monitoring is provided to carry out an optimum control of the time sequence
of PLC machines. If the power unit is ready for welding, a transistor will be switched on
(control sleeve, 4 poles, Pin 1; 4).
Operating voltage 24 V DC
Current capacity max. 50 mA
5.7.4 Contact
To control the sequence of PLC machines at best, an external contact inquiry is provided
between workpiece and welding head. If contact is signalled, the transistor is switched
on (control sleeve 3 poles, Pin 1; 3).
Operating voltage 24 V DC
Current capacity max. 50 mA
Operation of the automatic welding head KAH 412 (see opera-
ting manual).
5.7.5 RS232 Interface
Via the serial interface of the power unit, the actually recorded data can be output for
a potential storage in ASCII format.
A data cable is required which can be ordered as a consumable at HBS
(order no. 80-70-308).
Example for data output at serial output (e.g. Microsoft® Hyper Terminal)
