Trimpots Function - Weq EA08A Manual De Instalación Y Operación

3. IDENTIFICATION OF CONNECTION TERMINALS
E1- 110, 220, 380/440 : Sensing voltage (110/220/380 Vac).
F+, F- : Connection for alternator field.
X1, X2, Z1, Z2 : The power input can be Self-Excited Shunt, PMG, Harmonic, Full Harmonic and Auxiliary Winding.
S1-S2 : Connection for CT 5A of parallel operation.
S2-S3 : Connection for CT 1A of parallel operation.
VR-VR : Connection for potentiometer 1kΩ/1W (It should be isolated using twisted cable for connection).
A1-A2 : Analog input voltage. A remote DC voltage to adjust the output voltage of the alternator.
ATTENTION
1. Before connecting the regulator to the alternator, verify in the installation manual, the rated sensing
voltage.
2. Incorrect voltage and frequency adjustment can damage AVR.
3. If no potentiometer is used, keep EXT.VR terminal connected. (shorted).
