The generator output voltage has dropped below the minimum acceptable level. Under voltage can cause connected equipment to malfunction and indicates problems with AVR, excitation, speed control, or overloading.

Voltage drop under load indicates the generator may be overloaded, the AVR is not responding properly, or there is excessive voltage drop in connections. Check load vs capacity first.
Most AVRs have a voltage adjustment potentiometer. Adjust slowly while monitoring output with a meter. Only adjust with stable load and at correct speed.
