Measured parameter
Select one of the parameters listed below, that is the
parameter to be measured in the system by the
sensor connected to the actual analog input. See fig.

Overview of sensor locations
Unit
Electrical signal
Select signal type:
•
0.5-3.5 V
•
0-5 V
•
0-10 V
•
4-20 mA.
Sensor range, minimum value
Set the minimum value of the connected sensor.
Sensor range, maximum value
Set the maximum value of the connected sensor.
12.7 Digital inputs
To set the digital input, make the settings below.
Function
Select one of these functions:
•
Not active.
When set to Not active, the input has no function.
•
External stop.
When the input is deactivated (open circuit), the
pump stops.
•
Min. (minimum speed).
When the input is activated, the pump runs at the
set minimum speed.
•
Max. (maximum speed).
When the input is activated, the pump runs at the
set maximum speed.
•
"User-defined speed"
When the input is activated, the motor runs at a
speed set by the user.
•
External fault.
When the input is activated, a timer is started. If
the input is activated for more than 5 seconds,
the pump is stopped and a fault is indicated. This
function depends on input from external
equipment.
•
Alarm resetting.
When the input is activated, a possible fault
indication is reset.
•
Dry running.
When this function is selected, lack of inlet
pressure or water shortage can be detected.
When lack of inlet pressure or water shortage
(dry running) is detected, the pump is stopped.
The pump cannot restart as long as the input is
activated.
This requires the use of an accessory, such as
these:
– a pressure switch installed on the inlet side of
the pump
– a float switch installed on the inlet side of the
pump.
The priority of the selected functions in relation to
each other appears from section
.
A stop command always has the highest priority.
