HAND Reference Prime
Loss Level
Sets the level at which the drive will detect the Loss of Prime in the pump.
Note:
• If these conditions occur at the same time, the drive will detect LOP [Loss of Prime]:
–The monitor set by Y1-18 [Prime Loss Detection Method] ≤ S5-08 for longer than
Y1-20 [Prime Loss Time]
–Output frequency ≥ S5-05 [HAND Frequency Reference]
• The drive response to the Loss of Prime condition changes when the Y1-22 [Prime
Loss Selection] setting changes.
• Parameter Y1-18 [Prime Loss Detection Method] sets the units for this parameter.
