  • Operating Modes:

  • The operating mode can be selected using TEST or NORMAL Mode front panel Switch: 
  • NORMAL Mode:

  • > In this mode the AVR is operational. If PT input voltage is less than PT set point voltage minus hysteresis, then HIGH LED glow & there is a pulse of LOWER RELAY as per user setting pulse time & delay between two pulses & it clears if PT input voltage is greater than or equal to PT set point 
    > If PT input voltage is greater than PT set point voltage plus hysteresis, then LOW LED glow & there is a pulse of RAISE RELAY as per user setting pulse time & delay between two pulses, & it clears if PT input voltage is less than or equal to PT set point . 
    > If PT input voltage is less than UV set point then UV relay on & UV LED glow & it clears if PT input voltage is greater than or equal to UV set point plus hysteresis. 
  • TEST Mode:

  • > In TEST mode there is one potentiometer at front side of unit, it is independent of PT supply. 
    As per Potentiometer value voltage , Test Low & Test High LED glows as per PT voltage set point..
  • Settings:
  • > To enter settings mode press set key and then press increment key for enter the correct password. 
    > The password value can be set by using INC or DEC key & then press ENT key. 
    > Press set key to move to next parameter. To edit parameter press increment/decrement keys 
    > To save and exit SET mode press ENT key. 
    > If no key is pressed then controller automatically goes to initial Display normal mode.
