The different operating modes, functions and fault statuses have a dif‐
ferent effect on whether and how the pump reacts.
The following list shows the order:
1. - Priming
2. - Fault, Stop, Pause
3. - Auxiliary frequency (external frequency changer)
4. - Manual, External contact, Batch, External analogue
Comments:
re 1 - "Priming" can take place in any mode of the pump (providing it is
working).
re 2 - "Fault", "Stop" and "Pause" stop everything apart from "Priming".
re 3 - The "Auxiliary frequency" stroke rate always has priority over the
stroke rate specified by an operating mode listed under 4.
