1 Control and signal elements

Picture 1. Description of front control panel

LED ind

– it is ON in the case of inductive cosφ

LED cap

– it is ON in the case of capacitive cosφ

LED cosF

– it is ON when instantaneous or average value of cosφ is shown on the display

LED amp/volt

– it is ON when value of measured current/voltage is shown on the display

LED alarm

– it is ON when alarm is present

LED STAGES

– those LEDs indicate status of each stage individually

7. Buttons for regulator control

Picture 2. Device terminal connection PFC 6 RS and PFC 8 RS
