First
line of display indicates the PF value, inductive / capacitive PF,
mode of operation and fault /OK status:
“PF
= 1.000” indicates the overall PF of the system.
“+” or “-” indicates if this PF is inductive or capacitive respectively.
“A” or “M” indicates the Auto and Manual mode of operation respectively.
“ ” or “ ” indicates the Mains and Generator mode of operation respectively.
“OK” (blinking) indicates status of the system, healthy or faulty.
Last two characters represent one of the following status:
Second

‘I AM OK’ Blinking LED indicates the controller’s health status ,i.e. the
controller is working okay. If this LED stays continuously ON or
continuously OFF, then, it means the Controller is not functioning properly.
