SBM: Output as potential-free NO contact.
• Contact closed: pump operates in the specified operating mode.
• Contact open: pump off.
0-10 V: Control input.
• Remote setpoint adjustment: differential pressure control is active on the
pump. The setpoint for differential pressure is given by the analogue voltage
0-10 V (Fig. 1).
• Remote speed adjustment: differential pressure control is de-activated on the
pump. The pump operates as an actuator with a constant speed, which is
given by the voltage 0-10 V (Fig. 1).
DP: Interface between two pumps acting together as a double pump. The roles
of the two pumps (master/slave) and the operating mode (main/standby or par-
allel operation) can be set.
