PL-4016-00, Rev11, DCO# 18-057
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 “ON” (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.
State “Error”:
If an error according to Table 15 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 “ input the system gets back to the “ state.
Effect on Designated
Digital Output of the PLC
Temp. was higher than 90 °C for more than 10 minutes.
Temperature more than 90 °C
No motor temperature signal
Motor power cable not connected with controller
Motor sensor cable not connected with controller
Power channel interrupted
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)
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
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.
Dry Running Detection
- Pump keeps running on reduced speed (5000 rpm)
- The system accelerates to the set speed value when the pump is refilled
- Note that the speed is only reduced during dry running if the speed was ≥ 6000 rpm.
