15.9 Digital inputs
Available inputs depending on the functional module fitted in the
pump:
To set up a 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 will
stop.
• Min. (minimum speed)
When the input is activated, the pump will run at the set min.
speed.
• Max. (maximum speed)
When the input is activated, the pump will run at the set max.
speed.
• External fault
When the input is activated, a timer will be started. If the input
is activated for more than 5 seconds, the pump will be stopped
and a fault will be indicated.
• Alarm resetting
When the input is activated, a possible fault indication will be
reset.
• Dry running
When this function has been 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 will be 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 suction side of the pump
– a float switch installed on the suction side of the pump.
• Accumulated flow
When this function has been selected, the accumulated flow
can be registered. This requires the use of a flowmeter which
can give a feedback signal as a pulse per defined flow of
water.
See section 15.17.1 Pulse flow meter setup.
• Predefined setpoint digit 1 (applies only to digital input 2)
When digital inputs are set to predefined setpoint, the pump
will operate according to a setpoint based on the combination
of the activated digital inputs.
See section 15.15.2 Predefined setpoints.
The priority of the selected functions in relation to each other
appears from section 20. Priority of settings.
A stop command will always have the highest priority.
15.10 Digital inputs/outputs
Available inputs/outputs depending on the functional module
fitted in the pump:
To set up a digital input/output, make the settings below.

You can set the digital input/output 3 and 4 to act as digital input
or digital output:
