ProMinent Beta BT4b - 6.8 Hierarchy of Operating Modes, Functions and Fault Statuses

6.6 Functions
The functions are described below in the
"Operation" chapter.
6.7 Relays
The pump has two connector options.
The relay can close a connected power circuit,
in the event of for an
alarm buzzer, in the event of fault or warning indicating alerts, such
as a level warning.
The relay can be retrofitted through a knock-out opening in the pump
foot - refer to Retrofitting Relays and Ordering Information in the
Appendix.
This combined relay can generate a contact with each stroke from
its pacing relay in addition to its function as a fault indicating relay.
The relay can be retrofitted through a knock-out opening in the pump
foot - refer to Retrofitting Relays and Ordering Information in the
Appendix.
6.8 Hierarchy of Operating Modes, Functions and Fault Statuses
The different operating modes, functions and fault statuses have a
different 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.
