It shows the drive status during the pump control operation according to the following table:
Status
Description
REGL
Drive is regulating in PID mode.
PMAN
The drive is at protected manual mode.
OMAN
Drive is in manual mode, not protective mode.
HIPP
Drive is stopped (pause) due to high pressure, according to
the read data in the analogue input.
HIPR
A fault due to high pressure has occurred according to the
read data in the analogue input or in the digital input.
FLOD
The drive has stopped (Pause status) due to No Flow
detection.
NFLO
The drive has tripped (Fault status) due to No Flow detection.
CAVS
The drive has stopped (Pause status) due to Cavitation.
CAVI
The drive has tripped (Fault status) due to Cavitation.
LOPR
The drive has tripped due to low pressure fault.
LOWA
The drive has tripped due to a fault detected in one of the
digital inputs configured as ‘No Water’
CYCL
The drive has tripped due to excessive starting cycles.
IRFA
The drive has tripped due to a fault in the irrigation equipment
which has been detected in the digital input configured in that
option.
FLOW
The drive is limiting the speed to limit the flow.
OFF
The drive has received the stop command.
SLEP
The drive is in sleep mode because there is no flow demand.
BYPA
The drive is forcing the speed after starting or stopping some
of the fixed pumps.
RAMP
Set point ramp activated.
FILL
The drive is running at reduced speed because Pipe Fill
function is active.
COMP
The time of automatic stop has expired and the drive is
stopped.
JOCK
The Jockey pump is running.
PRIM
Priming pump is connected.
FINP
Fault occurred because the pressure switch is open.
Additionally, the reference in PID mode (as %) followed by feedback (as %) is shown.

The status of the three first fixed pumps is shown according to the next information:
Status
Description
OFF
Pump disabled by keypad.
RDY
Pump ready to start.
ON Pump
started.
FLT
Pump in a fault status (input which controls the signal is
active).
Note:
See digital input configuration in Pump Control mode.
G1.7 and G4.1.4 parameters are linked to this.
