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
described in the KSB ServiceTool supplementary operating manual.

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.
