• Predefined setpoint 1
The function applies only to digital input 2.
When you set digital inputs to a predefined setpoint, the pump
operates according to a setpoint based on a combination of the
activated digital inputs.
• Activate output
When this function is selected, the related digital output is
activated. This is done without any changes to pump operation.
• Local motor stop
When the function is selected, the given motor in a multimotor
system setup stops without affecting the performance of the
other motors in the system.
The priority of the selected functions are interdependent.
A stop command always has the highest priority.
Activation of digital inputs
You can set the digital inputs to trigger on either Closed contact or
Open contact. Selecting the trigger function can only be set via
Grundfos GO Link.
The digital inputs can be activated either as active low or active
high.
The digital inputs will react as described in the table below:
Activate/
Closed
contact
Deactivate/Open contact
GND/0V Floating/3-24V
7.10.1 Timer function for a digital input
Activation delay
The activation delay (T1) is the time between the digital signal and
the activation of the selected function.
Range: 0-6000 seconds.
Duration time
Available modes:
• Not active
• Active with interrupt
• Active without interrupt
• Active with after-run.
The duration time (T2) is the time which, together with the mode,
determines how long the selected function is active.
Range: 0 - 15,000 seconds.
