The "External Contact" operating mode is described below in the
"Operation" and "Installation, Electrical" chapters.
The "External Analogue" operating mode is described below in the
"Operation" and "Installation, Electrical" chapters.
6.6 Functions
The functions are described below in the "Operation" chapter.
6.7 Relay
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".
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 (pro‐
viding it is functioning).
re 2 - "Fault", "Stop" und "Pause" stop everything apart from "Pri‐
ming".
re 3 - The stroke rate of "Auxiliary frequency" always has priority
over the stroke rate specified by an operating mode in 4.
