7. OPERATION

 

7.1 

Switch On 

The 

Voltage 

R e g ul a t o r

 

Make sure all the loads connected to the voltage regulator are switched off. 
Make sure the 

MANUAL BYPASS SWITCH 

is on the 

"AVR" 

(or 

"II") 

position. 

Put the 

INPUT AIR BREAKER 

to 

"ON" 

position, the voltage regulator starts to work. 

Switch on the loads one by one.

 

7.2  Switch Off 

The 

Voltage 

Re g ula to r 

Switch off all the loads.

 

Put the 

INPUT AIR BREAKER 

to 

"OFF" 

position.

 

7.3  From Regulating Mode to Bypass Mode

 

Switch off all the loads.

 

Put the 

INPUT AIR BREAKER 

to 

"OFF" 

position.

 

Put the 

MANUAL BYPASS SWITCH 

to 

"BYPASS" 

(or 

"I) 

position.

 

Put the 

INPUT AIR BREAKER 

to 

"ON" 

position

 

Switch on the loads one by one.

 

7.4  From Bypass Mode to Regulating Mode

 

Switch off all the loads.

 

Put the 

INPUT AIR BREAKER 

to 

"OFF" 

position.

 

Put the 

MANUAL BYPASS SWITCH 

to 

"AVR" 

(or 

"II) 

position.

 

Put the 

INPUT AIR BREAKER 

to 

"ON" 

position.

 

Switch on the loads one by one.

 

7.5  Operation Of Display Panel

 

Each digital display shows the 

Input Voltage, Output Voltage, Output Current 

for each 

phase(A, B,C), and the 

Line Voltage 

(AB, BC, CA) for Input and Output. It also shows the 

status of the voltage regulator by means of symbol:

 

"L":   Output Under Voltage

 

"H": Output Over Voltage

 

"C": Transformer Windings Over Temperature

 

"F": Overload

 

"P": Input Wrong Phase Sequence

 

Press 

SWITCH BUTTON OF PHASE AND LINE VOLTAGE     

to switch the display 

between 

Phase Voltage 

and 

Line Voltage.

 

Press 

SWITCH BUTTON OF INPUT AND OUTPUT      

to switch the display between 

Input Voltage, Output Voltage, and Output Current.

 

Press down the 

DELAY BUTTON 

to select the delay time of 180 seconds, press 

it up to select the delay time of 6 seconds.
