  Parameter
   DT  - Delay time - Delay time of output closed despite no supply voltage, when the system detects the main (cutting) arc, 0.1~19.9s.
   HyS - Hysreresis - The hysteresis voltage - a rangge in which the voltage is measured, in which ther are signals controlling Up/Down, (+-1V ~ +-15V)
   StV - Started Voltage - Value of the off load voltage detection in the plasma cutter - uesd to detect the main (cutting) arc: 50~300V.

   DT  - (gecikme süresi) - sistem ana (kesme) arkı algıladığında besleme gerilimi olmamasına rağmen çıkışın kapanma gecikme süresi 0.1 - 9.9s fabrika ayarı: 0.5s
   HyS - (Histerezis) - Histerezis voltajı - bir aralık voltajın ölçüldüğü, sinyallerin olduğu UP / DOWN kontrolü 2-30V (± 1V - ± 15V) - fabrika ayarı: 8V (± 4V)
   StV - (Başlangıç Voltajı) - plazma kesicide yüksüz voltaj algılama değeri - ana (kesme) arkı algılamak için kullanılır: Varsayılan olarak 50-300V: fabrika ayarı 100V
