Page 266 A A Q Q -M210 -M210 Instruction manual Version: 2.04 Pick-up The Phase , I01 and I02 s etting parameters control the the pick-up and activation of the function. They define the maximum allowed measured current before action from the function. Before the function activates alarm signals, their corresponding pick-up elements need to be activated with the setting parameters Enable phase THD alarm , Enable I01 THD alarm and Enable I02 THD alarm .
