Page 13: Alarm And Protection
8. ALARM AND PROTECTION 8.1. Overload Protection When load is <120%, the voltage regulator won't give alarm and protection. Once the load is over 120%, the buzzer will beep once per 2 seconds, in the same time, the countdown time for output cutoff will be shown in the display. Once the countdown is finished, the output will be cut off by contactor, in the same time, symbol "F"... -
Page 14: Maintenance
9. MAINTENANCE The voltage regulator is basically maintenance free! But regular check and maintenance can extend its life span. 9.1. Preventive Method. Do not put any liquid on top of the voltage regulator. Try to install the voltage regulator in a clean place, avoid much dust, sandy area. 9.2. -
