5.1.2 State Description of Integrated Pump Controller
Pump
State “Off”:
The pump system is switched off and the impeller is not levitated. In this state,
Levitronix
®
Service Software
has full control.
Pump
State “Flow Control Mode”:
The pump system is switched ON and the impeller is rotating with the referenced flow.
Pump
State “Speed Control Mode”:
The pump system is switched ON and the impeller is rotating with the referenced speed.
Pump
State “Priming mode”:
The pump system is switched ON and the impeller is rotating with the priming speed. The motor has
electrical power when in this state. This mode can only be accessed by activating priming feature within
EEPROM-editor in
Levitronix
®
Service Software
. Priming speed and Timeout-time can also be configured
within EEPROM-editor.
Pump
State “Error”:
occurs in the pump system, the system defaults to the
Error
state. The
relevant digital output on the PLC Interface Module is activated. The pump system is switched OFF. By a
pulse of 300-700 ms on the
Enable/Reset
input the system gets back to the
Off
state.

Error = Open circuit
DC link (supply voltage) out of range (< 18 or > 30 VDC)
If the voltage is out of range the system starts to reduce the speed and a warning is generated. When reaching 0
rpm and the voltage is still out of range the system is disabled and an error is generated. In case the voltage is
again within the range during speed reduction the system switches to normal operation and no Error is generated.
Error = Open circuit

5.1.3 State Description of Integrated Flow Converter
Flow Converter Sta
te “Normal Operation”:
A flow sensor is connected to the integrated flow controller. The flow converter can measure a flow.
Flow Converter State “Measurement Error”
The flow converter cannot measure a flow due to at least one of the following reasons:
-
No flow sensor is connected to the flow controller.
-
There is no medium or too many air bubbles in the flow sensor.
-
The zero adjustment was made with a medium with different characteristics.
→
Zero adjust
Flow Converter State “Zero Adjustment in Progress”:
Zero adjustment procedure is in progress. The flow converter measures the current characteristics of the
medium and sets the current hydraulic condition in the flow sensor as 0 ml/min.
There should be medium inside the flow sensor and no flow during the zero adjustment procedure.
Flow Converter State “Zero Adjustment error”:
The last zero adjustment failed because of at least one of the following reasons:
-
No flow sensor is connected to the flow controller.
-
There is no medium or too many air bubbles in the flow sensor.
