Activation delay (only for input)
Select the activation delay (T1).
This is the time between the digital signal and the activation of the
selected function.
Range: 0 to 6000 seconds.
Duration timer mode (only for input)
Select the duration timer mode.
• Not active
• Active with interrupt (mode A)
• Active without interrupt (mode B)
• Active with after-run (mode C).
Select the duration time (T2).
This is the time which, together with the mode, determines how long
the selected function is active.
Range: 0 to 15,000 seconds.

Signal relay 1 and 2 (Relay outputs)
The pump incorporates two signal relays for potential-free signals.
For further information, see section Signal relays.
Function
You can configure the signal relays to be activated by one of the
following incidents:
• Not active.
• Ready. The pump can be running or is ready to run and no
alarms are present.
• Alarm. There is an active alarm, and the pump is stopped.
• Operating (Operation). Operating equals Running but the
pump is still in operation when the pump is stopped due to low
flow. See low-flow detection in section Stop function.
• Running (Pump running). The pump is running.
• Warning. There is an active warning.
• Limit 1 exceeded. When this function is activated, the signal
relay is activated. See section Limit-exceeded function.
• Limit 2 exceeded. When this function is activated, the signal
relay is activated. See section Limit-exceeded function.
• External fan control (Control of external fan). When you
select External fan control, the relay is activated if the internal
temperature of the motor electronics reaches a preset limit
value.
