Setting:
1. Select function mode with or .
2. Press [OK] to enable the function mode.
When you have selected the function of the input, specify the
sensor parameters by filling in the right values in unit, sensor

You can set the relay outputs to the following:
•"Not active"
•"Ready"
•"Alarm"
•"Operation".
The pump incorporates two signal relays for a potential-free
alarm signal, ready signal and operating signal. For further
information, see section 7.4.1 Relay outputs.
Set the function of the signal relays, alarm signal (factory setting),
ready signal and operating signal on the pump control panel.
The output is electrically separated from the rest of the controller.
The signal relay is operated as follows:
•"Not active"
The signal relay is deactivated.
•"Ready"
The signal relay is active when the pump is running or has
been set to stop, but is ready to run.
•"Alarm"
The signal relay is activated together with the red indicator
light on the pump.
•"Operation"
The signal relay is activated together with the green indicator
light on the pump.
