and the 'Error' identifier on the LCD screen, see also the "Trouble‐

Fault indicator (red): The fault indicator illuminates if a fault occurs e.g.
liquid level low 2nd stage".
Warning indicator (yellow): The warning indicator illuminates if the pump
electronics detect a condition which may lead to a fault, e.g. "liquid level
low 1st stage".
Operating indicator (green): The operating indicator illuminates provided
the pump is correctly connected to the operating voltage. The operating
indicator goes out briefly with every stroke.
The different operating modes, functions and fault statuses have a dif‐
ferent effect on if and how the pump reacts.
The following list shows the order:
1. - Priming
2. - Fault, Stop, Pause
3. - Auxiliary frequency (external frequency changeover)
4. - Manual, external contact, batch, external analog
