PRT-75 LDT Band
Width
If the source is detected below the set level, it must be adjusted to be above
the ‘LDT Level + LDT Band Width’ value to release the level detection fault trip.
If the source is detected above the set level, it must be adjusted to be below
the ‘LDT Level - LDT Band Width’ value to release the level detection fault trip.
The level detection trip bandwidth is 10% of the maximum source value.
PRT-76 LDT Freq
Sets the start frequency for the level detection. When setting the level
detection frequency, take into consideration the source type and the LDT level.
PRT-77 LDT
Restart DT
If PRT-08 (RST restart) is set to ‘YES,’ the inverter restarts after the time set at PRT-
76 elapses when an LDT trip is released. The LDT Restart operates each time an
LDT trip is released.
If PRT-77 is set to any other value than ‘0’ and the inverter is operating in HAND
mode, the inverter resets and the LDT trip is released. However, the inverter
stays in OFF mode and does not restart the operation instantly.

PRT-97 LDT Rst

PRT-98 LDT Cnt
Clr T
When the LDT trip occurs, the number of automatic restart is set by PRT-
96.
If an LDT trip occurs, the inverter automatically restarts after the time set
in PRT-77 (LDT Restart DT) has elapsed. The PRT-97 is incremented by
1 each time it is automatically restarted.
When the value of PRT-97 becomes equal to PRT-96, it does not try to
restart automatically.
The LDT trip will be restarted within the time set in PRT-98 after auto
restart
If not, PRT-97 is initialized to 0.
OUT-31–35 Relay
1–5
Sets one of the output relays to ‘32 (LDT)’ to monitor the level detection status.
