■
Function: Pump 3 Control (Setting: 41)
The multi-function digital output is configured to enable a third lag pump based on the normal operating conditions of the iQpump, which
determines when the third lag pump should be activated or deactivated. The operation of the digital output is determined by the
programming of the Pump Mode selection (P1-01).
If P1-01 = 1 or 2, the iQpump is programmed for drive only or drive + 1 pump; therefore, the Pump 3 Control output will be deactivated.
If P1-01 = 2, the iQpump will activate the Pump 3 Control output based on normal operating conditions.

■
Function: Pump Fault (Setting: 42)
The multi-function digital output can be configured to indicate a Pump Fault (H2-0x = 42). An open contact or output will indicate a
normal condition and that no Pump Fault has occurred.
A closed contact or output will indicate a Pump Fault has occurred. The following is a list of dedicated Pump Faults: Low Feedback
Fault, High Feedback Fault, Over Cycling Fault, Pump Protection Fault, Thermostat Fault, Low Water Fault, External Pump Fault.
Note: The Pump Fault function is active in Hand, Auto, Pre-charge and Thrust Bearing Modes. If the Pump Fault function is
used, one or both of the Pump Controls (Pump 2, pump 3) will not be available.
■
Function: Mot 2 Alternate (Setting: 43)
<0034>
Used in conjunction with the 2-motor alternation function.
Open: Motor 1 in use (or 2-motor alternation is disabled).
Closed: Motor 2 in use.
■
Function: Sleep Active (Setting: 44)
<0034>
Closed: Drive is in the sleep mode.
■
Function: Start Lvl Delay (Setting: 45)
<0034>
Closed: During the Start Level Delay Time (P1-05). Feedback has dropped below the P1-04 level and the drive is delaying running.
■
Function: Thrust Bearing (Setting: 46)
<0034>
Closed: The Thrust Bearing feature is active (output frequency is between zero and P4-05).
■
Function: Pre-charge (Setting: 47)
<0034>
Closed: The Pre-charge feature is active (configured by P4-01 ~ P4-03) - OR -
Closed: The Pre-charge 2 feature is active (configured by P4-12 or P4-13).
■
Function: High Feedback (Setting: 48)
<0034>
Closed: During a “High FB / Water” Fault - OR -
Closed: During a High Feedback” Alarm.
