The terminals are locked and resistant to external
voltage.
Dielectric strength: 250 V AC
Input for potential-free closed contact with the
x
function Ext. Off
contact closed: Pump works in standard mode.
Contact opened: pump still.
Contact load of the potential-free closed contact:
24 V DC /
10 mA
Dielectric strength: 250 V AC
Input for potential-free closed contact with the
x
function Ext. Min:
contact closed, Pump works in standard mode.
Contact opened: Pump runs at fixed min. speed.
Contact load of the potential-free closed contact:
24 V DC / 10 mA
Dielectric strength: 250 V AC
Output as potential-free opened contact with the
x
function operating signal SBM:
Contact closed: Pump works in the specified
mode.
Contact opened: Pump still.
Max. permissible contact load of the potential-free
opened contact: 24V AC, 1A.
Control input 0...10V:
x
Input resistance: >100 kV
Dielectric strength: 24 V
Accuracy: ± 5%
The following functions can be set:
Remote speed
adjustment: The pump's differential pressure
control is active. The set value
for the differential pressure is
given by the analog voltage
0...10V (Fig 12).
Representation in display:
Remote speed
adjustment: The pump's differential pressure
control is deactivated. The
pump works as an actuator at a
constant speed specified by the
voltage 0...10V (Fig 12).
