n L5-01: Number of Auto Restart Attempts
Sets the number of times that the drive may attempt to restart itself.
When the counter reaches the number set to L5-01, the operation stops and the fault must be manually cleared and reset.
The restart counter is incremented at each restart attempt, regardless of whether the attempt was successful. When the counter
reaches the number set to L5-01, the operation stops and the fault must be manually cleared and reset.
The number of fault restarts is reset to zero when:
• The drive operates normally for 10 minutes following a fault restart.
• A fault is cleared manually after protective functions are triggered.
• The power supply is cycled.
No.
L5-01
n L5-04: Fault Reset Interval Time
Determines the amount of time to wait between restart attempts when parameter L5-05 is set to 1.
No.
L5-04
n P1-01: Pump Mode
Selects the base operation mode of the drive controller.
No.
P1-01
Setting 0: Drive only
Designed for single pump stand-alone applications
Setting 1: Contactor lag
Contactor Lag systems multiplex a main pump with up to 5 lag pumps. The drive will stage and de-stage the lag pumps based
on system demand by using its digital output contacts to control the lag pump motor starters
Setting 3: MEMOBUS network
Up to eight drives can be networked together to provide for system redundancy and precise control.
When P6-01 > 0, the Flow Rate can come from another drive on the MEMOBUS Network.
Setting P9-40 to 0 (Analog) will read the Flow Meter from the analog terminal (H3-oo = 22) or from the pulse input (H6-01
= 5), while setting P9-40 to 3 (Network) will read the Flow Meter information from the network. When there is no such drive
on the network, a "Net Flow Meter Lost, Chk Source" alarm is triggered for drives with P9-40 set to 3 (Network) and P6-01
> 0.
Staging is disabled when and the drive PI output is influenced by the Water Level / Suction Pressure Control.
The functions listed below will behave slightly different when P1-01 is set to 3:
• Start Level: Active on the first pump in the network. Drives in the process of alternation will not undergo this process.
• Sleep: Active when the drive is the only drive running on the network.
• Over-cycle Protection: Active when the drive is the only drive running on the network.
• Pre-charge: Active only on the first drive to run in the network.
• Low City Pressure: Active on any drive in the network. An alarm condition will cause other drives in the network to stop
running and show a "Net Pump Err" message.
• Utility Delay: When this function is active, the drive is unavailable to the iQpump MEMOBUS Network and will force the
Home Screen text to show "Pump Off Network".
• Remote Drive Disable: When this function is active, the drive is unavailable to the iQpump MEMOBUS Network and will
force the Home Screen text to show "Pump Off Network".
