The AVR controller is a state of the art microcontroller technology based voltage regulating relay product form Proton. The AVR controller has the complete operating logic of the processes preprogrammed.
- 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..
- > 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.
> The factory set password is 11.
