11 Mechanised interlocks
Mechanised interlocks with metallic separation are only available factory
fitted.
11.1 RTC units with 7-pin interface (only for RTC 100
and RTC 150)
Input: – “Cutting on/off” closing contact, always required.
Output:– “Current-flow” message contactless for “Cutting arc on” Can be used for
external further processing, e.g. as precondition to starting control or
similar.
Article number: 756 1152
Standard: 5m cable
11.2 RTC units with 17-pin interface (only for RTC 100
and RTC 150)
Inputs: – Current set point for the range l
min
to l
max
linear 0-10V or connection of
potentiometer (< = 10 kOhm)
– “Cutting on/off” closing contact or “On” if U>18V
Outputs: – “Current-flow” message contactless for “Cutting arc on” Can be used
for external further processing, e.g. as precondition to starting
control or similar.
– Group alarm “RTC unit fault” by closing contact. Can be used for
external further processing, e.g. as error message on control or
similar.
- Actual value of cutting voltage 0-5V linear for 0-500V.Can be used
for external further processing, e.g. for arc voltage height control or
similar.
