Q5-09
(0F28) Low Suction Pressure
Detection Level
Low Pres Detect
Sets the level below which the suction pressure must fall for the
time set in Q5-10 to trigger a drive response according to Q5-11,
Low Suction Pressure Behavior Select.
Setting this parameter to 0.0 will disable the function.
Note:
Q4-10 detection time delay is only applicable
when Q4-11 = 2 or 3. When Q5-01 = 2, Q5-10
detection time delay applies to settings 1, 2, and
3.
Min.: 0.0
Max.: 1200.0
Q5-10
(0F29) Low Suction Pressure
Detection Time
Low Pres Det Tm
Sets the length of time that the water level must fall below the
level set in Q5-09 to trigger drive response. Applicable when
Q5-11 = 2 or 3. When Q5-01 = 2, Q5-10 detection time delay
applies to Q5-11 settings 1, 2, and 3.
Min.: 0.0
Max.: 300.0
Q5-11
(0F2A)
Low Suction Pressure
Behavior Select
Low Pressure Sel
0: No Display
1: Alarm Only
2: Fault
3: Restart (Q5-15)
Determines drive response when the suction pressure drops
below the level set in Q5-09 for longer than the time set in
Q5-10.
0: No display (digital output only)
1: Alarm only
2: Fault
3: Auto-restart (time set by Q5-15)
Note:
Q5-10 detection time delay only applies to
settings 2 and 3 while Q5-01 = 1. When Q5-01 =
2, Q5-10 detection time delay applies to settings
1, 2, and 3.
Default: 1
Range: 0 to 3
Q5-12
(0F2B) High Suction Pressure
Detection Level
Hi Pres Detect
Sets the level above which the suction pressure must rise for the
time set in Q5-13 to trigger a drive response according to Q5-14.
Setting this parameter to 0.0 disables the function.
Note:
Q5-13 detection time delay only applies when
Q5-14 = 2 or 3.
Min.: 0.0
Max.: 1200.0

Restart Time
Suction Restart
Sets the length of time that the drive will wait before attempting
an auto-restart of the Low Suction or High Suction fault.
Parameter is only effective when Q5-11 is set to 3 or Q5-14 is
set to 3 and L5-01 is greater than 0.
Default: 5.0 min
Min.: 0.1
Max.: 6000.0
