ACCUVAR - Operational Manual
2. If other parameters need to be changed, do so using similar method. Else, press key
for about four seconds continuously. The unit will restart and enter into run mode.
3. Setting Switching, Number stages, Meter Address and Baud rate
Normal (Contactor) OR Fast (Thyristor) switching is Site selectable. ACCUVAR supports
up to 15 capacitor bank stages. For user’s system requirement, the number of active
stages can be selected from 2 to 15. This is helpful in cases where the relay has been
purchased for higher number of stages but presently, fewer stages have been actually
connected. The Relay has RS485 port for external communication as an optional feature.
ACCUVAR supports MODBUS-RTU protocol on RS485 port. Each device on RS485 bus
should have unique address for proper functionality. Unit Address value is programmable
from 1 to 255. The baud rate for communication is programmable between 9600 or 19200.
To set the desired PF above parameters,
Once in Programming mode,
1. Set Arrow (>) to the desired parameters using and keys and press key. Now
Arrow (>) starts blinking which means value of this parameter can be set now. Set desired
value by using and keys and again press key to save its value.
2. If other parameters need to be changed, do so using similar method. Else, press key
for about four seconds continuously. The unit will restart and enter into run mode.
4. Setting operation type, Alarm Mode, Alarm Limit and Alarm Delay
If you have Solar panel installation at your site, select Solar else select Normal mode for
proper control action. The relay has an inbuilt alarm mode. In case, the relay ordered is of 8
stage, selecting the alarm mode as NO will keep it as 8 Stage relay. The Control action will
cover 8 Relays. If, however, you have selected alarm mode other than NO, the relay will
effectively become 8+1ALARM stage relay and the 16th stage will be used as an alarm
Contact.
