14.10 Pt100/1000 inputs
Available inputs depending on the functional module fitted in the
pump:
* See section
22. Identifying the functional module
Set the Pt100/1000 input for a feedback sensor via the "Assisted
pump setup" menu. See section
If you want to set a Pt100/1000 input for other purposes, you can
do this manually.
You can set the analog inputs via the "Setup, analog input" menu.
See section
If you perform the manual setting via Grundfos GO, you need to
enter the menu for the Pt100/1000 input under the "Settings"
menu.
Function
The Pt100/1000 inputs can be set to these functions:
• Not active
• Feedback sensor
• Ext. setpoint infl.
See section
14.17 External setpoint function
• Other function.
Measured parameter
Select one of the parameters, i.e. the parameter to be measured
in the system.
Select one of the parameters, i.e. the parameter to be measured
in the system by the Pt100/1000 sensor connected to the actual
Pt100/1000 input. See fig.

14.11 Digital inputs
Available inputs depending on the functional module fitted in the
pump:
* See section
22. Identifying the functional module
.
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 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
maximum 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. This function depends on input
from external equipment.
• 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:
– a pressure switch on the inlet side of the pump
– a float switch 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
can give a feedback signal as a pulse per defined flow of
water. See section
.
• Predefined setpoint digit 1 (applies only to digital input 2)
When digital inputs are set to a predefined setpoint, the pump
will operate according to a setpoint based on the combination
of the activated digital inputs. See section
.
The priority of the selected functions in relation to each other
appears from section
A stop command will always have the highest priority.
