time monitoring and faults (switch inputs)).
In the event of measuring value alarms, the respective measuring value is
additionally illustrated in red.
In the event of disruptions, the corresponding symbol appears in the IN list.
Alarms or faults must be pending for approx. 5 seconds before an alarm is
triggered.
The button can be used to deactivate the alarm relay temporarily,
without rectifying the fault.
The GRANUDOS starts now with the „start routine“
If a fault occurs again, or the fault is not rectified, the alarm relay will
be reactivated.
Tip!
An alarm will be automatically deleted when its cause has been remedied. When, for
example, the empty chemical container has been replaced.
However, the alarm switch-off time monitoring must be acknowledged manually!
Manual dosing (emergency programme)
In the event of a fault with the external measurement technology that
cannot be rectified, for a limited period of time, the disinfection dosing
and the dosing of the pH value regulation can be performed via the
emergency function Manual operation.

Main Menu Settings dosing performance chlorine/acid
The dosing performance menu serves for adjusting the dosing
performance to the expected consumption of chemicals in the pool.
Especially in case of lower water content, it is very important to adjust
the dosing performance.
The required dosing performance depends on several factors, e.g., the
basin volume, location, type of use and of course the frequency of use
by pool visitors.
Explanation of setting parameters
Chlorine: Dosing time of chlorine granulate adjustable from 1-15 seconds
Acid: Dosing time of acid in seconds adjustable from 1-8 seconds
ATTENTION!
The use of sulphuric acid is generally possible up to a concentration of 50%. For higher
concentrations or when using other acids (e.g. hydrochloric acid, dissolved sodium
bisulphate, etc.), the changed dosing performance and/or increased corrosiveness must
be observed! We recommend to consult with the company WDT!
Cycle: Length of complete dosing cycle adjustable from 30-360 seconds
Dosing time limit acid: Dosing time monitoring for external control adjustable from 0-100 minutes
Dosing time limit chlorine dosing time monitoring for external control adjustable from 0-100 minutes
Manual dosing off / on: Switch between automatic and manual dosing
Explanations of the dosing process
Chlorine and acid are dosed at intervals with pauses between the dosings.
The dosing is organised in dosing cycles (time from dosing interval to dosing interval) and dosing times (dosing times for
chlorine and acid dosing motors).
A dosing cycle proceeds like this:
1. Chlorine dossing - 1-15 sec.
2. Pause - 3.5 sec.
3. Acid dosing - 1-8 sec.
4. Pause until end of cycle
This cycle runs continuously with "manual dosing".
In "Automatic" mode, the cycle will also run, but the dosing will only be activated if the control command for dosing (chlorine
or acid) is pending. If the control command hits for a pause, the corresponding dosing will be activated in the next dosing
cycle.
Example for setting the dosing performance
Prerequisite: Indoor pool with a circulation capacity of 200m³/h. In accordance with DIN 19643, in indoor pools 2g of
chlorine must be added per each 1m³/h circulation capacity.
Calculation: 200m³/h x 2g chlorine = 400g/h chlorine dosing
Maximum dosing performance GRANUDOS 45 = 2000g/h = 100%
That means that the dosing performance must be set to 20% for a chlorine dosing of 400g/h.
The acid dosing is initially set to the same value, i.e., at 20%.
A readjustment may be necessary during ongoing operation.
Explanation of dosing time monitoring
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 large deviations from the target value. This means that the pause times must
always be greater than the dosing times. If, however, the dosing times are longer than the pause times, there is a fault with
the measuring and control device (e.g. control relay hanging) or the dosing performance is too low (set too weak or motor
or dosing screw faulty) or the input relay on the GRANUDOS control plate hangs. 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-control and pH-control or -dosing is monitored.

Explanation regarding the operation with external acid control (pH)
If a (existing) external dosing pump is to be operated for regulating the pH-Value, it must be remembered that the acid
dosing in the GRANUDOS is always active in order to avoid deposits in the solvent system.
In this case the acid control input can be clamped parallel on the chlorine control input (wire bridge).
With 230V control: on pin connector Nr. SL7 on the power plate NT-GRD, clamp 1+3 and clamp 2+4 is to brigde.
With potential-free control: on the I/O plate on pin connector Nr. SL10, clamp 1+3 and clamp 2+4 is to bridge.
Thus, during each chlorine dosing the acid dosing is activated as well. The dosing performance for the acid dosing must be
set to a low value here for the required cleaning function. However, it must also be checked whether the set dosing
performance is sufficient for the cleaning: the cyclone may not get turbid. See also Section 6.3.2.12, Page 22.
Tip!
It is urgently recommended to connect the pH-control at the GRANUDOS to avoid
acid overdosing in the event of a fault in the chlorine dosing.
Manual dosing Off/On
It is possible to change over to continuous manual dosing. This may be
required in the event of a fault with the measurement technology, e.g.
electrode failure, that cannot be rectified. For a limited period of time,
both the disinfection dosing and the dosing of the pH regulation may
be performed via the emergency function Manual operation.
After activation of Manual dosing, the display in the start screen
changes.
CAUTION!
In the operation mode Manual dosing, the operating personnel must continually check
the water quality and adjust the dosing amounts. Non-compliance with this may result
in significant incorrect dosing!

b) Main menu Settings System Password
Guest (user level 0)
No password, read-only rights
End user (user level 1)
There is no factory setting for an end user password. We recommend
the assignation of an end user password to protect the system against
unauthorised access. Enter the password in the operation data sheet.
The individual end user password must contain four digits between
0000 and 9999. In the second line, the password must be entered once
again.
Technician 1 (user level 2)
The Technician 1 password consists of five digits and has a factory
default setting of 01234. This password is intended for service
partners. We recommend that you change this password as well and
enter it in the operation data sheet.
If you place a green check mark next to Clear text, the entered
numbers are shown instead of white dots.
To change an active end user password, it must be entered in the upper
line. The new password must be entered in the two following lines.
If you wish to delete the end user password completely, simply enter the active password in the upper line.
The other two lines remain clear.
If an incorrect password is entered, an error message appears.
NOTICE!
Please store the individually chosen passwords safely in the operation data sheet. Lost
passwords can only be reset by the factory customer service!
