Alarm status
If the pump detects an alarm, the LED switches from green to red.
This can mean one of the following:
• low supply voltage
• blocked rotor
• electrical error.
The alarms for blocked rotor and electrical error can be read via the
PWM return signal, while all three alarms can be read via the LIN
bus signal.

Alarm status
If the pump detects one or more alarms, LED 1 switches from green
to red and one of the other LEDs lights yellow.
If multiple alarms are active at the same time, the LEDs only show
the error of the highest priority. The priority is defined by the
sequence of the table as shown in the fault finding information.
When there is no active alarm anymore, the operating panel
switches back to operating mode.
