The functions are described below in the "Operation" chapter.
The pump has two connecting options.
The relay can switch a connected power circuit (e.g. for an alarm horn) in
the event of warnings or fault messages (e.g. warning levels).
The relay can be retrofitted with the retrofit kit via a knock-out opening in
the pump foot - refer to "Retrofitting relays".
This combined relay can generate a contact with each stroke via its pacing
relay in addition to its function as a fault indicating relay.
The relay can be retrofitted with the retrofit kit via a knock-out opening in
the pump foot - refer to "Retrofitting relays".
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. - Test (priming)
2. - Fault, Stop, Pause
3. - Auxiliary frequency (external frequency changeover)
4. - Manual, Extern Contact
Comments:
re 1 - "Priming" can take place in any mode of the pump (providing it is
functioning).
re 2 - "Fault", "Stop" und "Pause" stop everything apart from "Priming".
re 3 - The stroke rate of "Auxiliary frequency" always has priority over the
stroke rate specified by an operating mode in 4.
