Relay outputs
• Relay output 1
• Relay output 2.
The relay outputs can be set to the following:
• Not active
• Ready
• Alarm
• Operation.
The pump incorporates two signal relays, terminals 1, 2 and 3, for
a potential-free alarm signal, ready signal and operating signal.
For further information, see section 5.5.1 Relay outputs.
Set the function of the signal relays, alarm signal (factory setting),
ready signal and operating signal, on the pump control panel.
The output, terminals 1, 2 and 3, is electrically separated from the
rest of the controller.
The signal relay is operated as follows:
• Not active
The signal relay is deactivated.
• Ready
The signal relay is active when the pump is running or has
been set to stop, but is ready to run.
• Alarm
The signal relay is activated together with the red indicator
light on the pump.
• Operation
The signal relay is activated together with the green indicator
light on the pump.

Setpoint influence
• External setpoint function
• Temperature influence.
13.7.1 External setpoint function
The external setpoint function is an external 0-10 V or 4-20 mA
signal that will control the pump speed in a range from 0 to 100 %
in a linear function. See fig. 37.
Fig. 37 External setpoint function, 0-10 V
3.1.12.0.0.0 Relay outputs
3.1.15.0.0.0 Setpoint influence
Range
4-20 mA [0-100 %]
0-10 V [0-100 %]
Control
0-20 % (e.g. 0-2 V) Setpoint = Min.
20-100 % (e.g. 2-10 V) Setpoint = Min. ↔ setpoint
Before the "
External setpoint function
" can be
enabled, the analog input must be set to "
External
setpoint influence
" via the "
Assist
" menu.
See section 5.6 Analog input for external sensor.
