5.11 P: Pump
• The "Low Feedback" fault is disabled when forward-acting PID is selected (b5-09 = 0) and the "High Feedback" fault is
disabled when reverse-acting PID is selected (b5-09 = 1).
• The "Not Maintaining Setpoint" fault is disabled.
• The "Feedback Loss" detection (4 to 20 mA wire break) is enabled, however, the Pre-Charge frequencies will override and
the b5-13 "feedback loss goto speed".
The drive will always exit Pre-Charge Mode when Pre-Charge times P4-03 and P4-07 have expired. The drive will also exit
Pre-Charge Mode when one of the following conditions are met:
• P4-03 and P4-32 are set to 0.0
• The "Disable Pre-Charge" digital input (H1-0o = 8C) closes.
• A digital input programmed to "Low Water" (H1-0o = 8F) is deactivated (open when P1-30 = 0 or closed when P1-30 =
1).
• The PID feedback satisfies both Pre-charge levels 1 and 2 (all must be true):
Pre-charge timers P4-03 and P4-07 have NOT expired
PID is enabled (b5-01 > 0).
PID is NOT disabled via digital input
Pre-Charge Level Set (P4-01 > 0) (and if used, P4-32 > 0)
Feedback is greater than Pre-Charge Level (P4-01) and Pre-charge Level 2 (P4-32) (forward-acting PID, b5-09 = 0) or less
than Pre-Charge Levels 1 and 2 (reverse-acting PID, b5-09 = 1)
Drive is NOT in a "Feedback Loss" condition (4 to 20 mA wire-break detection).
P2-04: Sleep Activate Level
n
When P2-01, Sleep Level Type, is set to 0 (Output Frequency / Speed), the Sleep function activates when the output frequency
is greater or equal to the level set in P2-04. When P2-04 is programmed to 0.0, the Sleep function activates above P2-02, Sleep
Level.
No.
P2-04
P2-05: Sleep Boost Level
n
Sets the amount of boost applied to the setpoint prior to going to sleep. A setting of 0.0 disables the sleep boost function.
No.
P2-05
P2-06: Sleep Boost Hold Time
n
Sets the amount of time the boosted pressure will be maintained before the drive goes to sleep.
No.
P2-06
P2-07: Sleep Boost Maximum Time
n
Sets the amount of time the system (feedback) has to reach the boosted setpoint. The drive goes to sleep when the amount of
time set in P2-07 is exceeded.
No.
P2-07
P2-08: Delta Sleep Feedback Drop Level
n
When the drive enters sleep mode, the software monitors the feedback to detect a flow-no flow condition. When the PID error
(setpoint minus feedback) exceeds the level set in P2-08 within the time set in P2-09 and the output frequency exceeds the
P1-06 setting, the sleep operation deactivates and the drive returns to normal operation.
No.
