2.2 The Drum Carrier
The rotating drum carrier assembly (6) is fixed to the main vertical support (10). The drum
(1) with chlorine is fixed on the carrier assembly (6) by band clamps ( ) and a retaining belt.
The dosing hopper (3) is fixed on the drum in place of the drum lid. The carrier with the drum is
then turned through 180° to the dosing position, the chemical is dosed into the dissolving
system (5) where it is fully dissolved and conveyed by a venturi to the buffer tank.
2.3 Chlorine Dosing Assembly
10 dosing hopper 16 hopper cover
11 dosing motor 17 knocker
12 dosing screw 18 seal washer
13 motor mounting 19 dosing hopper screw ring
14 dosing nozzle heated
15 drum empty switch with adjusting screw and ED
The dosing screw (1 ) meters the chlorine through the heated dosing nozzle (14) to the dissolving
system. If the drum empty switch (15) is indicating, app 1 kg chlorine is left in the hopper. The knocker
(17) gives a hit to the hopper wall at each dosing motor run cycle so supporting flowing of the granules.
Dosing performance is adjusted by the switch 4 at front fascia, see para "Start up operation".

2.4 Acid Dosing
The acid required for pH control is metered by the peristaltic pump to
the flushing water via the dosing injector. As the pH-control is vital for
the correct function of the chlorine/ORP-control, chlorine dosing is
stopped if the level switch at the supply carboy lance indicates container
empty. Besides this primary effect of controlling the pH-value, the dosing
of the acid at this point ensures an always clean dissolving system and
tubing, blockage of the injection valve is avoided.
As acid use one on base of sulphuric acid (37 – 50 %), please do not
use concentrated hydrochloric acid for this job as that penetrates the
peristaltic hose and will destroy the pump head. Diluted hydrochloric acid
may be not strong enough for the neutralisation job. Please note that using
dry acid (sodium bisulphate) 0% (= maximum concentration) is equivalent
to a only 10% sulphuric acid.
Maximum dosing performance is app. 3 l/h and is set as for chlorine.
The dosing cycle set for chlorine is valid for acid too.

least 0.2 bar. The pump pressure is controlled by the pressure switch ( 0) fitted on top of the pump. At
a pressure below the set switch pressure by sucking air or at pressure drops the machine stopps, lamp 1
& will burn. At works 1,5 bar is set.
The supply water is divided in the allocation rinsing water ( 8) at the discharge of the booster pump
( 6), one way leading to the flushing tank ( ), the other branch directed to the venturi nozzle ( 5),
where the water is sucked together with the dosed chemicals out of the flushing tank. The supply water
flow is controlled by means of a floating valve ( 1) and a flow switch ( 4), the latter being installed in
the suction tube of the venturi. To mix the chemicals and to ensure the complete dissolving of the
chlorine granules a cyclone mixing chamber ( 7) is fitted after the venturi.. To ensure that chlorine and
acid do not come into contact with each other in the open tank part of the dissolving assembly a
sophisticated control system is installed:
- metering of the two chemicals is regulated with pauses between the metering intervals
(para .6.3, page 11 “ Dosing Performance Dosing scheme ”).
- power supply for chlorine and acid dosing motors are connected by a relay system so that
only one or none of them can get power ( 4VDC) and dose chemical.
- flow switch ( 4) , level switch ( 9), pressure switch ( 0) supervising water supply and flow
conditions. If any non-compliance with the given limits occurs, the GRANUDOS will be
switched off.
2.6 Control System with program GR S41
The microprocessor based control of the GRANUDOS has three functions:
Contains the circuit self check and dosing and test programmes
Function control and interruption display (1 green + 4 red LED). If any
interruption is displayed, the GRANUDOS dosing is switched off.
All faults activate the fault remote control.
2.6.1 Operation elements
operation elements on front plate
- mains switch
- main fuse 3,15 Aslow
- 1 programme switch for test- and
Operation programmes
- 2 knobs to adjust the wanted dosing
performance for chlorine and acid
- 1 ED green to monitor operation
- 4 ED red to monitor irritations
operation elements inside on control plate:
2 fuses 500 mAslow,
Code switch to select programme alteratives
The control system is enclosed within a dust
proof and splash proof housing (IP 65). External switches and fault remote indication are to be connected
at the back of the control panel.

2.6.2 Operation and Test Programmes
Leistungssteller für Chlor und Säure:
By turning the programme switch there is a retention time of seconds with flashes of the green lamp
At the performance knobs for chlorine and acid the dosing performance that is selected by the code
switches on the control plate is reduced to the wanted one.
Auto:
Dosing control by external auto-controller free chlorine and pH-
value. Dosing always within the dosing cycle advance or at the next
cycle. The cycle is to be set on 1 minute with code switch S1 on
“on”, or on 6 minutes with code switch S on “off”. Dosing of
chlorine and acid is independent.
Auto monitor.: as „Auto“ but with dynamic time monitoring: :
When controlling the GRANUDOS dosing by an external auto-
controller the dosing performance must be set high enough to
ensure the dosing times (= dosing performance) of acid and
chlorine shall not exceed 50% of total time, the actual values are
near to the set points of free chlorine and pH. If the controller
output time exceeds 50% , there must be any interruption in the
system:
- dosing performance set too low
- interruption at the dosing motor or dosing screw
- interruption at the auto control system: hanging relay,
faulty electrode etc.
The GRANUDOS controller S4 adds up all demanded dosing
time (input time) that exceeds50% of total time and stops dosing
if 60 minutes excess time is reached: Indication by flashing of the
red lamp 3 (acid) or 4 (chlorine).
Hand
Continuous dosing as set. Dosing cycle as set on code switch S
”on”1 minute, “off” 6 minutes..
With the longer cycle time you get a lower dosing performance
Test chlorine:
Test chlorine dosing for 6 minutes continuously, then stop, the green lamp flashes
Can be used to test the real dosing performance.
Test acid:
Test acid dosing for 6 minutes continuously, then stop, the green lamp flashes.
Can be used to test the real dosing performance
Test knocker
Test for knocker function: the knocker hits 4 times all seconds then stop, the green lamp flashes
Dos-off
Dosing switched off, the booster pump continues. Used for maintenance.
Off:
Switch off of all functions. Used if the machine is taken out of operation for a longer period.
Used also for a restart of the machine after switch off by the fault “level low – pump pressure”
Dosing can be switched off by an additional external switch e.g. a flow or pressure switch
in the measuring water tubing or in the circulation to prevent dosing if there is an
interruption.
