Sets one of the output relays to ‘32 (LDT)’ to monitor the level detection
status.
<An example of PRT-71 set to (1: Above Level)>
As shown in the figure above, level detection can be carried out (relay output is ‘on’) as the output
frequency is above PRT-76 frequency for the PRT-73 time and above the PRT-74 detection level.
The LDT operation is reset if the LDT Source (PRT-72) value is less than the PRT-74 level
subtracted from the PRT-75 value (band width).
The LDT operation is carried out if the inverter operation is above PRT-74.
Modify PRT-74 and PRT-75 appropriately when modifying LDT Source of PRT-71.
PRT-74 and PRT-75 become default value if the LDT Source is modified.
PRT-77 (Restart DT) and PRT-08 (RST restart) features operate separately.
The inverter waits until the delay time set at PRT-73 (LDT Dly Time) before it operates based on
the setting in LDT-70 when the level detection time condition is met.
