Danfoss VLT - Fire Mode Live Zero Timeout Function; Terminal 53 Low Voltage

6-02 Fire Mode Live Zero Timeout Function
Option: Function:
The function set in par. 6-01 Live Zero Timeout Function will be activated if the input signal on
analogue inputs is below 50% of the value defined in parameter group 6-1* to 6-6* "Terminal xx
Low Current” or “Terminal xx Low Voltage" for a time period defined in par. 6-00

3.8.3 6-1* Analog Input 1
Parameters for configuring the scaling and limits for analog input 1 (terminal 53).
6-10 Terminal 53 Low Voltage
Range: Function:
0.07 V* [Application dependant] Enter the low voltage value. This analog input scaling value should correspond to the low reference/
feedback value set in par. 6-14
Terminal 53 Low Ref./Feedb. Value .
6-11 Terminal 53 High Voltage
Range: Function:
10.00 V* [Application dependant] Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/feedback value set in par. 6-15
Terminal 53 High Ref./Feedb. Value .
6-12 Terminal 53 Low Current
Range: Function:
4.00 mA* [Application dependant] Enter the low current value. This reference signal should correspond to the low reference/feedback
value, set in par. 6-14
Terminal 53 Low Ref./Feedb. Value . The value must be set at >2 mA in order
to activate the Live Zero Time-out Function in par. 6-01
Live Zero Timeout Function .
6-13 Terminal 53 High Current
Range: Function:
20.00 mA* [Application dependant] Enter the high current value corresponding to the high reference/feedback set in par. 6-15 Terminal
53 High Ref./Feedb. Value
