start display –Automatic
The device is in the Automatic operation mode. The device doses upon request via an
external controller. The set dosing performance is displayed.
There is no fault.
NOTICE!
The dosing stops once you switch to the main menu by pressing “Enter” and only starts
again once you switch back to the start display. After 10 minutes without entry, the
system automatically switches back to the start display.
Start display - Startup routine –Delay booster pump - Dosing delay
The startup routine:
If the device is started via the CCT, the startup delay runs for the booster pump “Start
delay b-pump”. The startup delay is used to ensure that no air enters the booster pump
during the subsequent operation.
Setting the delay time under “Settings”“Start delay b-pump”
If the specified pump pressure is reached within 6 seconds after the start of the booster
pump, the dosing delay then runs (for a fixed 3 sec) and the dosing device switches to
the set operation mode. The remaining times are displayed at the bottom in each case.
Startup mode:
If the specified pump pressure or the minimum water level is not reached/undercut within 6 seconds after
the start of the booster pump or also during operation (fault “Pressure min”, “Level min”), a startup mode
of 120 sec. starts again up to 5x. In this case, the Boosterpump runs for 6 seconds, then pauses until 120 sec.
The remaining times are displayed at the bottom in each case. If the specified values for pressure/level are
not reached, the device enters the fault mode.
Software alarms are suppressed during this time.
6.4 The Main Menu
The main menu is reached by pressing “Enter”.

Start display –Fault indication –Acknowledge alarm
If a fault occurs, this will be indicated by a red display and the fault indication in the
bottom line.
For a description of the fault indications, see Chapter 7.2, Fault removal.
Faults must be pending for 6 seconds before a notification or an alarm is triggered.
A distinction is made between alarms (software alarms, e.g., dosing time monitoring,
monitoring switch) and notifications (e.g., “Chlorine empty”).
Examples for fault indications / alarm
Dos-limit Cl = Dosing time limit for chlorine exceeded
pH empty = pH (= acid canister) empty
Cl empt = Chlorine tank empty
Fuse F2 = Fuse F2, for details, see Chapter 7.2,. Fault removal
NOTICE!
An alarm will automatically be deleted when its cause has been remedied. For example,
the empty chemical container has been exchanged with a full one.
Acknowledge alarm
Use the Enter key to switch to the main menu
Use the arrow keys to navigate to the “Reset alarm” menu item
Press the Enter key
The alarm relay is temporarily deactivated; this does not rectify the fault! If the fault subsequently recurs,
or if the fault is not rectified, the alarm relay will be reactivated.
Navigate back to the operation mode; this will restart the device.
Special cases
The two alarms for the dosing time monitoring “Dos-limit” cannot automatically be deleted and must
always be acknowledged manually!
In case of the faults “Pressure min” or “Level min” the startup mode starts 5 times for 120 seconds
each to check if the fault is still pending. (See Chapter 6.3.2)
oIf the fault is rectified during the 5 startup attempts, the device returns to the previous state, e.g.,
automatic operation.
oIf the fault still continues after this, the GRANUDOS switches off.
oIf the GRANUDOS has switched off, the fault must be acknowledged manually. To do so, the “Reset
alarm” command must be carried out twice: Once to reset the alarm, and once to reset the startup
delay. Now, the GRANUDOS will start up again and the cause of the fault can be investigated.

Main menu Settings Dosing performance/Dosing time monitoring/dosing process
The Dosing performance menu is used to adjust the dosing performance to the expected consumption of
chemicals in the pool.
The required dosing performance depends on several factors, e.g., the pool volume, location, type of use and,
of course, the pool’s frequency of use.
Explanation regarding the dosing process
Chlorine and acid are dosed at intervals with pauses between the dosing cycles.
The dosing performance is determined by the set cycle time, the set dosing times (running time of the dosing
motors for chlorine and acid) with the intermittent pauses.
A dosing cycle proceeds as follows:
1. Chlorine dosing: 1-15 sec.
2. Pause: 3.5 sec. fixed
3. Acid dosing: 1-8 sec.
4. Pause until end of cycle –etc.
With “Manual dosing”, this cycle runs continuously.
In “Automatic” operation, this cycle also runs; however, the dosing is only activated if the control command
for the dosing (chlorine or acid) is pending. It the control command encounters a pause, the respective dosing
is activated in the following cycle.
Chlorine and acid dosing are independent; dosing occurs when the external controller requests chlorine or
acid –but always in the cycle, so that chlorine and acid can never be mixed in the open flushing tub.

Control Unit, GRANUDOS S5
Index: 03 Change date: 09/01/2024 OI No.: BA SW 014-03 Granudos S5-Steuereinheit EN.docx Page 13 of 31
Explanation of the setting parameters
Chlorine: Dosing time for chlorine granulate in seconds per cycle, can be set from
1-15 sec. The dosing performance set in this way can be seen on the start display. It
is best to use the “shortcut”, see Chapter 6.2.
pH (acid): Dosing time for acid in seconds / cycle, can be set from 1-8 sec.
Cycle: Length of entire dosing cycle in seconds, can be set from 30-360 sec.
The cycle time must be set first. If the cycle time is changed, the dosing performance
for chlorine and acid changes at an equal ratio.
Dos-limit Cl: Dosing time monitoring for the chlorine dosing with external control,
can be set in minutes from 0-100 min. This prevents overdosing in case of a fault in
the control: For an explanation, see 6.4.1.8.
Dos-limit pH: Dosing time monitoring for the acid dosing with external control in
minutes from 0-100 min. –see dosing time limit for chlorine.
Explanation of dosing time monitoring “Dos-limit Cl/pH”
If the GRANUDOS is controlled by a measuring and control device, the dosing performance must be set
sufficiently high so that even large loads can be regulated without significant deviations from the target value.
In case of a pulse width modulation (PWM), this means that the pause times must always be greater than the
dosing times, since the actual values should approach the target values. However, if the dosing times are
longer than the pause times, then either the dosing performance is too low (set too weakly, or motor or
screw are defective), or there is a malfunction in the measuring and control device (control relay stuck, contact
defective) or a fault in the GRANUDOS control board.
The dosing time monitoring totals the dosing times against the pause times, and if the set dosing time limit is
exceeded, dosing is deactivated and indicated as a fault.
Both the chlorine and pH control respectively dosing are monitored.
Example for calculating the realisable dosing performance required according to DIN 19643
In accordance with DIN 19643, in indoor pools 2 g of chlorine must be added per each 1 m³/h circulation
capacity. In outdoor pools, a dosing capacity of 10 g/m³h is required as a possible dosing performance.
Calculation: Thus, for an indoor pool with 600 m³ and a circulation capacity of 200 m³/h, a dosing
performance of 200 m³/h x 2g chlorine = 400g/hour must be possible.
In the delivery state, the maximum dosing performance of the GRANUDOS is displayed in the start display
according to the installed dosing technology. (see also Chapter 6.4.1.6/6.4.1.7 Config. Cl / pH)
Example for setting the dosing performance
1.Chlorine dosing
In an indoor pool, the usual chlorine requirement is around 200-300 g/100 m3 water content per day. For
a 600 m3pool, this equals 250 x 6 = 1500 g/day or 150 g/hour with 10 hours of circulation time. If the
GRANUDOS is designed with a dosing technology of 1600 g/h –see “Config. Cl”, about 150 g/h should be
set with continuous dosing without measuring and control technology. To do so, the cycle could be reduced
to 60 seconds and the dosing time could be reduced so that the start display (see above) displays approx. 150
g/h
If a measuring and control technology is present, the dosing performance must be set about 2-3x as high
to be able to control demand peaks. In this case, a dosing performance of 300-400 g/h would be required.
Set the cycle to 30 seconds here and reduce the dosing time until about 350 g/h is displayed.
In an outdoor pool, with fair weather the chlorine consumption is about 5x as high, i.e., in the above pool,
a dosing performance of approx. 700-800 g/h should be provided. With the assumed incorporated dosing
performance of 1600 g/h, the cycle should therefore be set to 30 seconds, and the dosing performance
should be set to the desired value.
After a few days, a readjustment may be necessary, according to the obtained measuring results –
measuring value deviations from the target value!
2. Acid dosing
No exact prediction can be made for acid consumption. The actual demand for chemicals depends on the
concentration of the acid, frequency of use by pool visitors and the specific local conditions (fresh water pH,
hardness, temperature) and must be readjusted according to the measuring values:
At the start, the acid dosing is adjusted to approximately half of the chlorine dosing; e.g., if chlorine is 600g/h,
then set acid to approx. 300ml/h. (With 37% sulphuric acid).

ATTENTION!
The use of sulphuric acid is generally possible up to a concentration of 50%. With
higher concentrations or when using other acids (e.g., hydrochloric acid, dissolved
sodium hydrogen sulphate, etc.), pay attention to a change in dosing performance
and/or increased corrosiveness! We recommend consultation with the manufacturer!
NOTICE!
When refilling the pool, the pH value must be manually brought to the desired value,
since a relatively large amount of acid is required to reach the desired value with a high
pH-value and extreme hardness. This would take too long if only using the
GRANUDOS’s acid pump. The result would be a poor disinfection performance at a
high pH-value, or possibly a fault indication because the target value has not been
reached.
Main menu Settings Shock chlorination
With this menu, you can adjust the dosing performance for chlorine and pH for a shock
chlorination. Please select a dosing performance that ensures the availability of the
desired concentration during the shock chlorination.
This dosing performance is used when a filter disinfection is requested by the CCT.
For monitoring purposes, the chlorine concentration should be checked several times
during shock chlorination.

Main menu Settings Control (password entry)
Control via external measuring and control technology
CORROSIVE!
The measuring and control technology must not switch the GRANUDOS device on or
off under any circumstances, but only the dosing unit –see wiring diagram. Any
necessary shutdown of the GRANUDOS must not take place during cycle. The dosing
cycle must always be able to run unimpeded. Otherwise, a chemical back-up could
occur when flushing the chlorine granulate, resulting in chlorine gas formation!
This setting determines the control mode of the chlorine and acid dosing and can only
be executed by entering the password.
a) Control PWM = Pulse width modulation (standard)
The controller output is organised in cycles. The control signals come with 230 VAC or potential-free. After
capturing the input signal, the GRANUDOS doses for chlorine or acid using the set performance. If the input
signal is pending for a longer time than the set cycle duration, another dosing is carried out in the following
cycle.
NOTICE!
The shortest signal duration should be at least 2 seconds long to ensure accurate
dosing.
Explanation about the operation with an external acid dosing pump for regulating the pH-
value; only possible with PWM control
If an (existing) external dosing pump is to be operated for regulating the pH-value, it must be considered that
the acid dosing in the GRANUDOS must also always be active in order to avoid deposits in the dissolving
system.
For this purpose, the acid control can be clamped parallel on the chlorine control (electric wire bridge).
With 230 V control: on SL3 terminal 1+3, plus bypass 2+4.
With potential-free control: on SL8 terminal 1+3, plus bypass 2+4.
Thus, during each chlorine dosing the acid dosing is activated as well. For the required cleaning function, the
dosing performance for acid dosing must be set to a low value. However, it must be checked if the set dosing
performance is sufficient for the cleaning; the mixing cyclone must not get cloudy. See also Chapter 6.4.1.1,
page 12, Example for setting the dosing performance.
CAUTION!
It is urgently recommended in this case to also connect the pH-control at the
GRANUDOS in parallel to avoid acid overdosing in the event of a fault in the chlorine
dosing.
TIP!
As a rule, the pH-value in the pool is set with the acid dosing at the GRANUDOS.

b) Frequency control pH external, Cl external
The maximum number of impulses (frequency) of the external control technology is set
on the GRANUDOS up to max. 200 impulses/minute. The GRANUDOS now always
counts the incoming impulses per minute, calculates the requested dosing performance
on this basis and doses the respective amount in the following cycle.
In this case, an input signal of 200 impulses/minute results in 100% dosing
performance.
An input signal of 100 impulses/minute results in 50% of the set dosing
performance.
The setting must be made separately for the pH and chlorine control.
c) Manual control = Manual dosing
It is possible to change over to continuous dosing. This may be required in the event of
a fault in the external measuring technology, e.g., electrode failure, that cannot be
rectified at short notice.
“Manual dosing” can only be selected for both chlorine and acid dosing together.
Upon activation of Manual dosing, the status line on the start display changes from
Automatic to Manual dosing.
CAUTION!
In the “Manual dosing” operation mode, the water quality must be checked
continuously and the dosing performance must be adjusted to the current
consumption. Non-compliance with this may result in considerable incorrect dosing!
Main menu Settings Teach Cl full (optional)
TIP!
This function is not available in the standard design; it only works in combination with
a special sensor.
The switch for the Chlorine empty notification in the device is a capacitive proximity
switch. This switch must be recalibrated, if necessary. The justage is carried out as
follows.
Full adjustment (justage):
Full adjustment can only be carried out if the dosing hopper contains granulate!
Fill chlorine granulate into the dosing hopper (for GRANUDOS Flex +
GRANUDOS 15), or attach the chlorine drum (for GRANUDOS 45/100) and
pivot into the dosing position.
Carry out the full adjustment in the menu via “Teach Cl full” Full adjustment. The
process is started by pressing the Enter key; it runs for 12 seconds. The full
adjustment has now been carried out.
For the standard design, the justage is described in the Operating Instructions
for the respective dosing device.
