7.3 Functions
7.3.1 Remote ON/OFF (digital input)
CAUTION
External voltage applied to the RUN terminal
Damage to the printed circuit board!
▷ Always use a volt-free contact for the RUN terminal.
CAUTION
Using digital inputs for safety-relevant shutdown
Pump does not stop!
Damage to the electronics!
▷ For safety-related shutdown always separate the unit from the power supply
network (e.g. by installing an Emergency OFF system).
The digital input is factory-set to start up and stop the pump set.
The digital input can also be configured. For configuring use the KSB ServiceTool as

Contact Effect
Contact closed/ terminals bridged Pump set starts up.
Contact open/ terminals not bridged Pump set stops.
7.3.2 External analog 0-10VDC signal
CAUTION
External voltage applied to the RUN terminal
Damage to the printed circuit board!
▷ Always use a volt-free contact for the RUN terminal.
Function
An external analog 0-10VDC signal serves as setpoint input. If the Constant-
pressure Control, Proportional-pressure Control or EcoMode operating modes are
active, the pump set processes the current external analog signal as a setpoint. If the
Open-loop Control operating mode is active, the pump set processes the external
analog signal as a speed setpoint. If the signal level <1.5VDC, the pump will stop
and the last LED segment will extinguish.
