Measured parameter
Select one of the parameters, such as the parameter
to be measured in the system by the Pt100/1000
sensor connected to the actual Pt100/1000 input.
See fig. 40.

13.10 Digital inputs
* See section 7.5.1 Connection terminals,
advanced functional module, FM 300.
To set 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 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 stops 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 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 stops. The
pump cannot restart as long as the input is
activated. This requires the use of an accessory,
such as:
– a pressure switch installed on the inlet side of
the pump
– a float switch installed on the inlet 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 gives a
feedback signal as a pulse per defined flow of
water. See section 13.18 "Pulse flowmeter
setup".
• Predefined setpoint digit 1, applies only to digital
input 2.
When digital inputs are set to predefined
setpoint, the pump operates according to a
setpoint based on the combination of the
activated digital inputs. See section
13.16.2 "Predefined setpoints".
The priority of the selected functions in relation to
each other appears from section 16. Priority of
settings. A stop command always has the highest
priority.
