Codes de défaut couverts
15-94
High line voltage may result in increased stress on electronic components and shorten the life of VFD. “Line Voltage High” fault is set when incoming line voltage rises above 285V AC RMS at any time, or when line voltage rises above 280V AC RMS for more than 5 seconds. Once line voltage drops below these thresholds the fault will clear. While fault is active unit will not operate or will shut down if already running. This fault does not escalate to a malfunction.
On 26VNA/27VNA models, this measurement is taken at the secondary side of the 24VAC transformer and a scaler value applied at the factory to correct for transformer variation. On 27VPA models, the VFD measures the line voltage directly.
