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. |
