8. TRIMPOTS FUNCTION
Vad: Voltage Adjustment.
Stb: Stability Adjustment.
U/F: Adjusting the beginning of the range of the Protection U/F= Constant.
Drp: Droop adjustment.
9. STATEMENT OF LED’S
OK: Regulator is on
Oexc: On: Under stress acting
Off: Over voltage not acting.
Hz: ON: U/F acting.
Off: U/F not acting.
10. TRIMPOTS ADJUSTMENT
Vad: Turning clockwise increases the voltage and counterclockwise decreases.
Stb: Turning clockwise slower response and faster counter-clockwise.
U/F: Rotating clockwise decreases the range of U/F and counterclockwise increases.
Drp: Turning clockwise increases the reactive compensation range and counterclockwise decreases.
Note: Of the regulators encapsulated version, can be connected potentiometer for fine voltage adjustment (5k

/3W,
preferably 10 laps) on terminals with this symbol
