6.1.1 Display mode
Either the operating status or the alarm status is shown in display
mode.
Operating status
If the pump is in operation, LED1 lights up green. The other four
LEDs show the current power consumption (P1) according to the
following table. When the pump is running, the active LEDs light
up permanently in display mode. This differentiates the display
mode from the settings mode. In settings mode, the active LEDs
flash. If the pump is switched off via the external PWM signal, the
green LED1 flashes. The
LEDs do not light up.

Alarm status
If one or more faults occur, the LED1 lights up red. If an alarm is
active, the yellow LEDs show the cause of the fault according to
the following table. If multiple faults are active at the same time,
the LEDs indicate the fault with the highest priority. The priority is
shown in the following table.
If an alarm is no longer active, the display switches back to the
operating status.
