Ref Value
(Current Input)
4..20 mA = 0..10000 rpm (speed mode)
-> Speed Limit = 9000 rpm 18.4mA
-> Cut-off (min.) speed = 300 rpm
4..20 mA = 0..100% (process mode)
- Grounds are internally connected
- Direct connection, no protection.
Galvanic isolation on the user side
is required.
- Default input settings:
Current inputs selected.
Voltage input can be selected with
EEPROM–editor in Levitronix

24 V active
0 V not active
24 V active
0 V not active
Switches between process mode
and speed mode
24 V active, system on
0 V not active, system off
The Enable signal switches the
pump system on and off.
Relay closed active, system on
Relay open not active, system off
This signal indicates the state of
the pump system.
Relay closed not active, system on
Relay open active, system off
When active, the system drives the
impeller to zero rpm and shuts
down. With a reset pulse the
system can be re-initialized.
Relay closed not active, system o.k.
Relay open active, system not o.k.
The warning signal indicates if a
system fault has been detected.
The warning signal indicates a
system fault, but the system does
not shut down
Default Setting:
Trend Warning
Relay closed warning active
Relay open warning not active
Default setting: Relay closed if
trend warning is active. Can be
changed in EEPROM with
Levitronix
®
Service Software.
Option:
Priming Valve
Signal
Relay closed Prime valve signal active
Relay open Prime valve signal inactive
Can be used to control a priming
valve for priming of the pump.
Feature can be activated and
configured with Levitronix
®
Service
Software.
