In this table, load represents the equipment with which you are using the Voltage Stabilizer. Symptom Possible cause Solution Voltage Stabilizer does not switch ON, none of the LEDs are illuminated. Voltage Stabilizer has turned off automatically. Voltage Stabilizer appears to function normally but the load will not turn ON. Voltage Stabilizer appears to function normally but the output voltage is consistantly low. Voltage Stabilizer's LEDs are all on at one time, or no LED is lit. The fuse has blown. The power supply to the stabilizer is not available. Power switch circuit breaker has tripped. Load is not plugged in. Load is not switched ON. Load fuse has blown. The supply voltage is too low due to continuous brown-out. The supply voltage is too low because the unit is rated at 230 V but the supply is 110 V. Possible internal fault, which could be temporary or permenant. Very bad power supply waveform or frequency. Replace the fuse (see Replacing the fuse on p. 17). Make sure the incoming power supply is available. Verify that the current load does not exceed the capacity of the stabilizer and that you are using the correct voltage. Make sure the incoming power supply is not excessively low or high. Reset the circuit breaker. If it trips again and the power supply is normal, return for repair. Verify that the load is plugged in. Verify that the input voltage is within the input range of the stabilizer. Verify that the load is switched ON. Replace the load fuse (see Replacing the fuse on p. 17). Resolve the power supply problem. or Return the unit for a stabilizer rated at the correct voltage. Verify that the current load does not exceed the stabilizer's rating.
