VLT ® 6000 HVAC■ List of warnings and alarmsThe table gives the different warnings and alarmsand indicates whether the fault locks the frequencyconverter. After Trip locked, the mains supply must becut and the fault must be corrected. Reconnect themains supply and reset the frequency converter beforebeing ready. A Trip can be reset manually in three ways1. Via the control key [RESET]2. Via a digital input3. Via serial communication In addition, anautomatic reset may be selected in parameter400 Reset function.Wherever a cross is placed under both Warning andAlarm, this can mean that a warning precedes thealarm. It can also mean that it is possible to programwhether a given fault is to result in a warning or analarm. This is possible, e.g. in parameter 117 Motorthermal protection. After a trip, the motor will becoasting and on the frequency converter alarm andwarning will flash. If the fault is removed, only thealarm will flash. After a reset, the frequency converterwill be ready to start operation again.No. Description Warning Alarm Trip locked1 10 Volts low (10 VOLT LOW) x2 Live zero fault (LIVE ZERO ERROR) x x4 Mains imbalance (MAINS IMBALANCE) x x x5 Voltage warning high (DC LINK VOLTAGE HIGH) x6 Voltage warning low (DC LINK VOLTAGE LOW) x7 Overvoltage (DC LINK OVERVOLT) x x8 Undervoltage (DC LINK UNDERVOLT) x x9 Inverter overloaded (INVERTER TIME) x x10 Motor overloaded (MOTOR TIME) x x11 Motor thermistor (MOTOR THERMISTOR) x x12 Current limit (CURRENT LIMIT) x x13 Overcurrent (OVERCURRENT) x x x14 Earth fault (EARTH FAULT) x x15 Switch mode fault (SWITCH MODE FAULT) x x16 Short-circuit (CURR.SHORT CIRCUIT) x x17 Serial communication timeout (STD BUSTIMEOUT) x x18 HPFB bus timeout (HPFB TIMEOUT) x x19 Fault in EEprom on power card (EE ERROR POWER) x20 Fault in EEprom on control card (EE ERROR CONTROL) x22 Auto-optimisation not OK (AMA FAULT) x29 Heat-sink temperature too high (HEAT SINK OVERTEMP.) x30 Motor phase U missing (MISSING MOT.PHASE U) x31 Motor phase V missing (MISSING MOT.PHASE V) x32 Motor phase W missing (MISSING MOT.PHASE W) x34 HPFB communication fault (HPFB COMM.
