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 is rotating with the referenced flow/pressure. The motor
has electrical power when in this 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 can also be configured within EEPROM-editor.
State “Error”:
occurs in the pump system, the system defaults to the
Error
state. The
according digital output on the PLC Interface Module is activated. The pump system is switched OFF. By a
pulse off 300-700 ms on the
Enable/Reset
input the system gets back to the
Off
state.

DC link (supply voltage) out of range (< 18 or > 30 V DC)
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

5.2.2 Operation with Fieldbus (RS485)
See
Section 4.3.5
5.2.3 Operation with User Panel LUI-B.1
The RS485 interface can also be used with the user panel
LUI-B.1
, which has basically the same menu
functions as the
Stand-Alone
model (described in
Section 5.1
). The relevant configurations are illustrated in
for the
OEM
and in
for the
EasyConnect
driver models.
5.2.4 Operation for Serial Pumping
