4.7 High Feedback Level Alarm and Fault Setup
◆ P1-09, P1-10, P1-13
Table 4.14
The iQpump drive continuously monitors the systems feedback device and has the ability to show an alarm and/or fault the iQpump drive
when the feedback signals rise above a programmed high feedback level (P1-09) for a programmed high feedback level fault delay time
(P1-10).
The hysteresis level (P1-13) determines the high feedback alarm turn-off level. In case of a high feedback alarm, the alarm message will
turn-off when the feedback level falls below the programmed high feedback level (P1-09) minus the hysteresis level (P1-13).

The Drive will display a “High Feedback Level (HFB)” alarm when
the feedback level rises above the programmed level. The alarm will
turn off when the feedback level falls below the programmed High
Feedback Level minus the Hysteresis Level (P1-13). This function is
active during running in the hand mode, auto mode, pre-charge and
thrust-bearing mode.

The Drive will initiate a “High Feedback Fault (HFB)” when the
feedback level rises above the programmed level for a time specified
in P1-10. The Drive will coast to a stop when a fault occurs. This
function is active during running in all operation modes.
