The pump incorporates two signal relays for potential-free
signalling. For further information, see the section on megging.
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 the section on
low-flow detection.
• "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
the section on the limit-exceeded function.
• "Limit 2 exceeded".
When this function is activated, the signal relay is activated. See
the section on the 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 reach a preset
limit value.
Factory setting
See the section on factory settings.

Whether the analog output is available or not, depends on the
functional module fitted in the pump:

See the section on the identification of functional module.
The analog output enables the reading of certain operating data to
external control systems.
To set the analog output, make the settings below.

• "0-20 mA"
• "4-20 mA".
