Low Level Behavior – Auto-Restart:
The drive attempts to auto-restart after the PI Aux Level Control Auto-Restart Time (Q6-15) expires if the drive faults out on
a “LOAUX – Low PI Aux Lvl” Fault, parameter Q6-11 = 3, and L5-01 > 0 to enable auto-restarts. The auto-restart counter
increments and the drive remains faulted until the feedback rises above the level set in Q6-09.

PI Aux High Level Detection
Set Q6-01 to 1 and Q6-12 > 0 to enable PI Aux High Level Detection.
High Level Behavior – No Display:
The High PI Aux Level digital output (H2-0o = 9F) closes when Q6-14 = 0 (No Display) and the PI Aux Feedback rises
above the level set in Q6-12. The digital output opens when the feedback falls below the level set in Q6-12.
High Level Behavior – Alarm Only:
The “HIAUX – Hi PI Aux Lvl” alarm displays and the digital output closes when Q6-14 = 1 (Alarm Only) and the PI Aux
Feedback rises above the level set in Q6-12. The alarm clears and the digital output opens when the feedback falls below the
level set in Q6-12.
High Level Behavior – Fault:
The digital output closes and the alarm displays when Q6-14 = 2 or 3 (Fault), the output frequency > 0, and the PI Aux Feedback
goes rises above the level set in Q6-12. The drive faults out with a “HIAUX – Hi PI Aux Lvl” fault when the feedback remains
above the Q6-12 level for the Q6-13,
High Level Behavior – Auto-Restart:
The drive attempts to auto-restart after the PI Aux Level Control Auto-Restart Time (Q6-15) expires if the drive faults out on
a “HIAUX – Hi PI Aux Lvl” Fault, parameter Q6-14 =“3, and L5-01 > 0 to enable auto-restarts. The auto-restart counter
increments and the drive remains faulted until the feedback falls below the level set in Q6-12.
