Levitronix BPS-2000.1 User Manual page 37

State "Off":
The pump system is switched off and the motor has no power. In this state, Levitronix Service Software has
full control.
State "ON" (speed control mode):
The pump system is switched ON and the impeller is rotating with the referenced speed. The motor has
electrical power when in this state.
State "ON" (process control mode):
The pump system is switched ON and the impeller speed is controlled in order to get the referenced
flow/pressure. The motor has electrical power when in this state.
State "Error":
If an error according to Table 16 occurs in the pump system, the system defaults to the Error state. The
designated digital output on the PLC Interface is activated. The pump system is switched OFF. By activating
the "Reset" input the system gets back to the "Off" state.
Error Source Errors
Motor No rotor
Motor Temperature over 100°C
Motor Temp. was higher than 90°C for more than 10 minutes.
Motor Temperature more than 90°C
Motor No motor temperature signal
Motor Motor power cable not connected with controller
Motor Motor sensor cable not connected with controller
Controller Over-current
Controller Power channel interrupted
Controller Temperature over 80°C
Controller Temp. was higher than 70°C for more than 10 minutes.
DC-link voltage error < 90 VDC or > 378 VDC
(Corresponds to supply voltage of < 64 VAC or > 267 VAC)
Controller
If the voltage is out of range the system starts to reduce the speed to 0 rpm and
the controller goes into an error state.
DC-link voltage warning > 90 VDC and <130 VDC
(Corresponds to supply voltage of > 64 VAC or < 92 VDC)
If the measured DC-link voltage is < 130 VDC and > 90 VDC the speed is limited to
Controller
max. 4000 rpm and a warning is generated. If the measured DC-link voltage
returns within the voltage input range of > 130 VDC and < 378 VDC, the system
switches back to normal operation.
Controller Temperature over 70°C
Dry Running Detection
- Pump keeps running on reduced speed (5000 rpm)
Controller
- The system accelerates to the set speed when the pump is refilled with liquid.
- Note that the speed is only reduced during dry running if the pump speed was ≥
6000 rpm
Table 16: Errors and warnings with indication on PLC interface
- Standard firmware is E1.48 for "High Flow" and E2.48 for "High Pressure" systems
- For other configurations of error codes refer to alternate controller or firmware documentation
