5.2.4 Functional and Fault Indicators
The fault indicator lights up if the fluid level in the dosing tank falls
below the second switching point of the level switch (20 mm
residual filling level in the dosing tank).
The fault indicator lights up if the current falls below 3.8 mA (only
with 4...20 mA) or exceeds 23 mA in "External Analogue" operating
mode.
This LED flashes in the event of an undefined operating status.
The warning indicator lights up if the fluid level in the dosing tank
falls below the first switching point of the level switch.
The operating indicator lights up if the pump is ready for operation
and there are no fault or warning alerts. It goes out quickly as soon
as the pump has performed a stroke.

6 Functional description
6.1 Liquid End
The dosing process is performed as follows: The diaphragm is
pressed into the dosing head; the pressure in the dosing head
closes the suction valve and the feed chemical flows through the
discharge valve out of the dosing head. The diaphragm is now
drawn out of the dosing head; the discharge valve closes due to
the negative pressure in the dosing head and fresh feed chemical
flows through the suction valve into the dosing head. One cycle is
completed.
6.2 Drive Unit
The diaphragm is driven by an electromagnet, which is controlled
by an electronic controller.
6.3 Capacity
The capacity is determined by the stroke length and the stroke
rate.
The stroke length is adjusted by the stroke length adjustment knob
within a range of 0 ... 100 %. A stroke length of between 30 ... 100
% (SEK type: 50 ... 100 %) is recommended to achieve the speci‐
fied reproducibility!
Data Value Unit
Recommended stroke length,
standard type
30 ... 100 %
Recommended stroke length, SEK
type
50 ... 100 %
The stroke rate can be set within a range of 10 ... 100 % using the
multifunctional switch.
6.4 Self-Bleeding
Self-bleeding liquid ends (SEK types) are capable of independent
priming when a discharge line is connected and diverting existent
air pockets via a bypass. During operation they are also capable of
conveying away gases which are produced, independently of the
operating pressure in the system. It is also possible to dose pre‐
cisely in a depressurised state due to the integral back pressure
valve.
6.5 Operating modes
The operating modes are selected by means of the multifunctional
switch.
As soon as the stroke rate has been set by the multifunctional
switch, the pump finds itself in "Manual" operating mode. 100%
corresponds to 180 strokes/min.
"Manual" operating mode
Functional description
19

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.
