Key Features:

  • The Parameter setup can be done through 4 nos. of soft keys on front fascia
  • Keys on the front panel is used to
    • Scroll, increment, decrement through display parameter,
    • To set the Meter ID,
    • Time, Date,
    • Change password.
==> Press scroll key once the parameter set is completed, this allows to view the parameters one after the other automatically (change over time period is 4 secs). If this is not done auto scroll will not happen.

Meter Descriptions:-

Mode Selection:

  • Auto/Manual Key is used for Mode Selection. When press it , display ask for PASS WORD.
  • Once enter the correct Pass Word , display will highlight the present mode (either Auto Or Manual) by blinking.
  • Now with UP or Next Key the required Mode can be selected
  • By pressing Mode Key the selected Mode is registered .It can be viewed by concern LED on Auto/Manual Key.

Auto Mode:

  • In Auto Mode , the APFC monitor the instant KVAr, and calculates the average KVAr at the interval of 5 sec.
  • If the average KVAR is inductive, the controller will switch on the corresponding capacitor bank to get the unity PF.
  • If the KVAR is Capacitive, turn Off the Bank which is suitable to get the unity PF.
  • Note: Capacitor bank ON Status will be shown by concern Yellow LED on front fascia .

Manual Mode:

  • Capacitor bank can be switched ON and OFF manually by pressing corresponding switch (CB1 to CB12).
  • The reconnection is possible only after the set time which is programmable.
  • Reswitching On time is programmable and OFF time is 5 Sec.

Capacitor Read:

  • In set mode, we can execute the Capacitor read function.
  • APFC read the KVAR Value in Capacitor banks and store in the location C1 to Cn. (where n is the no of Stages)

Capacitor Value:

  • In set mode, we can enter the KVAr Value for health checking.

Health Checking:

  • Limits of health checking are programmable.
  • If banks are Unhealthy capacitor banks are indicated by glowing red LED.

Input Supply:

  • Both voltage and current circuit should take from the same phase.

Set Parameters:

  • Device ID
  • CT Value
  • Required PF
  • Capacitor Read (CAP rd)
  • Reconnection Time (rt)
  • Capacitor Value
  • Unhealthy Limit
  • Real Time
  • Real Date
  • Change Password

Enabling Auto scroll / Manual Scroll :

  • Enabling Manual scroll: Press Stop/Scroll key to enable manual scroll mode Now parameters can be viewed one by one using Up and Next Keys
  • Enabling Auto scroll : When display in manual mode, press Stop/Scroll to enter into auto scroll mode. Parameters will scroll 4 secs. one after the other. By default, when meter is switched ON it will be in auto scroll mode.
