Description Attribute

Acceleration

This element serves a feedback that the pump rotation accelerates.

CleanValveOpen

This element serves a feedback about the open state of the cleaning valve.

Deceleration

This element serves a feedback that the pump rotation decelerates.

FlushValveOpen

This element serves a feedback about the open state of the flush valve.

GasDilValveOpen

This element serves a feedback about the open state of the gas dilution valve.

InletValveOpen

This element serves a feedback about the open state of the inlet valve.

NoRotation

This element serves a feedback that the pump stands still.

OutletValveOpen

This element serves a feedback about the open state of the outlet valve.

ProcessIsActive

This element serves a feedback that the process is active.

PumpActivation

This element serves a feedback about the activation state of the pump. The activation state takes into account that control mechanisms are active. Never the less the pump is not necessarily running

PumpDirection

This element serves a feedback of the pumps direction of rotation.

PumpOperation

This element serves a feedback about the operation state of the pump. In the operation state the pump rotor is rotating.

PumpPowerMax

This element serves a feedback of pump operating at maximum power.

PumpSpeedMax

This element serves a feedback of pump operating at maximum speed.

PumpSpeedMin

This element serves a feedback that the pump operates at minimum speed.

PurgeValveOpen

This element serves a feedback about the open state of the purge valve.

RatedSpeed

This element serves a feedback that the pump rotation is at rated speed.

StandBy

This element serves a feedback about the process standby of the pump. In the stand by state the pump is ready for operation.

StandBySpeed

This element serves a feedback that the pump rotation is at standby speed.

TargetSpeed

This element serves a feedback that the pump is at target speed.

VentValveOpen

This element serves a feedback about the open state of the vent valve.
