9.8 Remote control
The remote control interface is for connecting a hand or foot remote control. It is also possible to use the
interface for a small automation application.
In case of “inpermissible“ short circuits between the connector pins of the interface, the machine will stop
and displays E11 (remote control conn.). Also if the start contact is closed during switching on the ma
-
chine, the machine shows E11 in the display.
Schematic
Ω
signal pin designation
weld start 1 and 2 as soon as pin 1 and 2 are connected, the machine starts (same function as
pressing the torch trigger switch)
weld energy 4 analog input for setting the weld energy (e.g. with an potentiometer)
0V = minimum setting of the actual welding program
15V = maximum setting of the actual welding program
! CAUTION ! this analog input is only valid if the identification “external“ on
pin 6 and 7 is active
identification “external“ 6 as soon as pin 6 is connected to pin 7 (gnd), the analog input (pin 4) is valid
and the decimal point in the lower rigth corner of the ampere display is lit.
ground 7 gnd for the identification signals on pins 6 and 8
identification “2 stroke“ 8 as soon as pin 8 is connected to pin 7 (gnd), the machine operates in 2-stroke
mode at “weld start“
arc established 9 and 10 as soon as welding current is flowing, this relay contact is closing pin 9 to 10
maximum contact load: 1A
