18 TERMINAL CONNECTION
E1/E2: Single-phase sensing voltage.
E3/4: Power supply voltage and single-phase sensing voltage common connection
3: Power supply.
: Connection to 5k / 3W potentiometer (for external voltage control).
F+ e F-: Connection to exciter field of the generator.
JHz: Jumper 50/60 Hz (JHz position 1-2 = 50 Hz – position 2-3 = 60 Hz).
JR: Sensing voltage selector Jumper (pins 1-2 = 160 to 300V, pins 2-3 = 320 to 600V).
