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 17 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
Temperature 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
Temperature was higher than 70°C for more than 10 minutes.
Supply voltage out of range (Power input)
(Ext. range: < 90 or > 378 V DC corresponds to < 64 VAC or > 267 VAC Input)
If the voltage is out of extended range the system starts to reduce the speed and
an error is generated. When reaching 0 rpm and the voltage is still out of extended
range the system is disabled.
Supply voltage out of range (Power input)
(Nominal range: < 130VDC corresponds to 180VAC Input)
If the voltage is below nominal range still within extended range than performance
reduction may be possible at higher flows and speeds and warning is generated.
For DC voltages < 130 but >90 VDC the speed is limited to 4000 rpm.
Dry Running Detection
Pump keeps running on reduced speed (5000 rpm)
The system accelerates to the set speed value when the pump is refilled with liquid
Note that the speed is only reduced during dry running if it was ≥ 6000 rpm
