removed. Otherwise, exciter field voltage keeps on over 85 ±5Vdc for 10sec, or instantaneously it exceeds 100Vdc. After shutdown, to reset the regulator, generator set should be stopped or the power input to the AVR Should be interrupted for more than 20second ...

Remove the jumper from the terminal 6 and 7, and connect the remote voltage adjust potentiometer (rheostat) to the terminals 6 and 7 as specified. ▶ Sensing voltage Generator voltage sensing is single-phase 220Vac or 380Vac. It can be selected in accordance with generator output voltage (or rated voltage) as follo ...

▶ turning CCW decrease damping level to cause under damping 6.6. Choice frequency switch depending on generator frequency (SW1) This option protects generator and AVR by decreasing generator output voltage if it reduces generator frequency. (under frequency protection) - Fr ...

7) Reconnect all wires. 8) Start engine and check the output voltage. ● ● ● ●NOTE To take flash exciting without engine running, keep the button on a pushed condition to close the flash exciting circuit for 30sec. 7.2. AUTOMATIC FILED FLASH EXCITING Whenever start generator set, to avoid no out ...

SYMPTOM CAUSE ACTION Residual Voltage- No Output Residual voltage at regulator power input wires 3 & 4 below 3Vac. Field leads F+, F- not connected. Power input leads not connected. Blown or missing fuse. Defective regulator. Defective generator. Check ...

Incorrect connections. Voltage adjust turned down. Remote voltage adjust is turned down. Defective regulator. Check wiring diagram for proper connections. Incorrect sensing voltage connection can cause output voltage low-no adjustment. Rotate voltage adjust CW until desired voltage is reached. Rotate remote voltage adjust CW until desire ...
