VLT ® 2800 SeriesProgramming0 - Temp. MAX 0-20 mA/4-20 mA.An output signal is obtained, which is proportionalto the present heatsink temperature. 0/4 mAcorresponds to a heatsink temperature of less than20 °C, and 20 mA corresponds to 100 °C.323 Relay output 1-3(RELAY 1-3 FUNCT.)Value:No function (NO OPERATION) [0]✭Unit ready (UNIT READY) [1]Enable/no warning (ENABLE/NO WARNING) [2]Running (RUNNING) [3]Running in reference, no warning( RUN ON REF/NO WARN) [4]Running, no warnings(RUNNING/NO WARNING) [5]Running in reference range, no warnings(RUN IN RANGE/ NO WARN) [6]Ready - mains voltage within range(RDY NO OVER/UNDERVOL) [7]Alarm or warning(ALARM OR WARNING) [8]Current higher than current limit, par. 221(CURRENT LIMIT) [9]Alarm (ALARM) [10]Output frequency higher than f LOW par. 225(ABOVE FREQUENCY LOW) [11]Output frequency lower than f HIGH par. 226(BELOW FREQUENCY HIGH) [12]Output current higher than I LOW par. 223(ABOVE CURRENT LOW) [13]Output current lower than I HIGH par. 224(BELOW CURRENT HIGH) [14]Feedback higher than FB LOW par. 227(ABOVE FEEDBACK LOW) [15]Feedback lower than FB HIGH par. 228(UNDER FEEDBACK HIGH) [16]Relay 123 (RELAY 123) [17]Reversing (REVERSE) [18]Thermal warning (THERMAL WARNING) [19]Local operation (LOCAL MODE) [20]Out of frequency range par. 225/226(OUT OF FREQ RANGE) [22]Out of current range(OUT OF CURRENT RANGE) [23]Out of feedback range(OUT OF FDBK.

The output is activated (1-2make) when a given condition is fulfilled.Description of choice:No function. Is selected if the frequency converteris not to react to signals.Unit ready, there is a supply voltage on the controlcard of the frequency converter, and the frequencyconverter is ready for operation.Enable, no warning, the frequency converteris ready for operation, but no start commandhas been given. No warning.Running is active when there is a start commandor the output frequency is above 0.1 Hz. Alsoactive during ramp-down.Running in reference, no warning speedaccording to reference.Running, no warning, a start command hasbeen given. No warning.Ready - mains voltage within range, the frequencyconverter is ready for use; the control card isreceiving a supply voltage; and there are noactive control signals on the inputs. The mainsvoltage lies within the voltage limits.Alarm or warning, the output is activated byan alarm or warning.Current limit, the output current is higher than thevalue programmed in parameter 221 Current limit I LIM .Alarm, The output is activated by an alarm.Output frequency higher than fLOW, the outputfrequency is higher than the value set in parameter225 Warning: Low frequency, f LOW.Output frequency lower than f HIGH , the outputfrequency is lower than the value set in parameter226 Warning: High frequency, fHIGH.Output current higher than I LOW, the outputcurrent is higher than the value set in parameter223 Warning: Low current, ILOW.Output current lower than I HIGH, the output currentis lower than the value set in parameter 224Warning: High current, I HIGH.✭ = factory setting.
