State “Off”:
The pump system is switched off and the motor phases have no power (current). The Setpoint Speed can be
modified with the Up and Down buttons, without any effect on the system states.
State “On (Speed Control)”:
This state can be reached by manually activating the system with the On/Off button. The impeller is levitating
and rotating with the Setpoint Speed, which can be manually adjusted with the Up and Down buttons. The
motor has electrical power when in this state.
State “On (Controlled by PLC)”:
This state can be reached by activating the digital input on the PLC connector (see Table 8). The pump
system is switched on and the impeller is levitating and rotating with the Setpoint Speed, which is adjusted
with the current of the analog input (see Table 8).). The motor phases have electrical power when in this
state.
State “Error”:
If an error occurs, the system switches to the Error state. The pump system is disabled. The system switches
back to the “Off state by pushing the On/Off button or by a pulse of 300-700ms on the digital input of the
PLC interface (see Table 8).

or repetitive timer. The values are selected with the On/Off button, and modified with the Up and
Down button.
Menu Tab 2: System Information
