TOPAX
®
DX Multichannel controller
The active charcoal and the flocculation central dosage can be subse-
quently turned off."
Parameter Range
Disinfection: Minimum 0.30 and adjustable maximum between
0.60 and 1.20 mg/l
(adjustable, as the DIN Standards 19643 do not
clearly indicate the upper limit value)
pH value: pH 6,5 – pH 7,6
Redox: > 700 mV
Combined chlorine: < 0.20 mg/l
Tab.: Parameter for DIN-Contact
For all measuring outputs the hysteresis must be known.
The DIN contact is closed when all the measured values are in the ad-
justed range.
ATTENTION!
The values for the DIN-contact can be set in the
“Service - DIN-contact” menu. If the values for the
DIN-contact need to be changed, e.g. the “Disin-
fection” value with a Whirlpool, then working in the
“Configuration” menu, menu item 0.4.11: switch
on the contact “Output DIN-contact”, otherwise the
menu item “DIN-contact” cannot be accessed in the
“Service” menu.
ATTENTION!
If no total chlorine was measured and thus no com-
bined chlorine was determined, the contact can be
used when combined chlorine is proven to be within
the DIN range by means of photometric analysis.
In the economy mode there are two variants:
14.1 TOPAX DX is responsable for economy mode
During initial configuration of the in- and outputs, the TOPAX DX re-
quests the "DIN contact". For the DIN contact, one of the options is
"ECO-control". If this mode is switched on, the following functions are
activated:
Save the "ECO - control" and enter the following menu to select the type
of contact (relay or optocoupler). This contact is called "ECO - contact".
The DIN values are internally compared. If all DIN values are respected,
the ECO-contact is set as "ECO-default mode" and will be activated
every time when the night-time mode or timer is manually switched on.
To reduce the circulation capacity, working in the “Night mode menu
(see section “19.1.11 Menu 2.4: Night operation” on page 35) enter
the reduced circulation capacity in % and set the reduced setpoint for
the “disinfection” measurement. If you enter this lowest value as a per-
centage figure, all controller parameters will be adjusted accordingly to
this lower percentage. Reduction rate up to 50 % are admissible.
When the TOPAX DX is set on night-time reduced operation mode, the
“Night-time operation” contact must be externally set to provide a feed-
back confirming that the recirculation capacity was actually reduced.
The economy mode is effective only when a confirmation is given. Lack
of compliance to DIN - parameters at the time of switching to night-time
saving mode, will activate ongoing comparative timer check-up and the
ECO contact will be actually active as soon as the DIN-parameters are
in place.
14.2 TOPAX DX only transfers the DIN-contact
If the DIN-contact is transferred outwards, this can be processed in
a management system. Responsibility in this case is not carried by
TOPAX DX. The "Night-time operation" menu will have to be reset as
well as the recirculation capacity.
15 Startup after a long shut down period
If the TOPAX DX is switched off for a long period, it is possible that hu-
midity (condensate) accretes within the housing. This can mean that the
high-resistance inputs (pH value and Redox) no longer function correctly.
In such cases, the TOPAX DX must be dried out before start-up: Close
the housing and switch on the TOPAX DX. No further humidity should be
present after c. 12 – 24 hours in this state, and the faulty input should
readjust itself.
IMPORTANT!
To rule out the build-up of condensate water, we recom-
mend that the TOPAX DX remain switched on during down-
time.
16 Control of the flocculation pump
For the control of the flocculation central pump different possibilities
can be selected.
16.1 Control proportional to the pure water throughflow
Input signal 0/4…20 mA
Adjustment range 0-100 %
(Disturbance factor input)
16.2 Control with direct input
In the night operation mode the dosing pump can be operated for re-
duced flocculation capacity. The following operation modes can be se-
lected in the "service" menu for the control of the flocculation pump:
• Operating mode Off
• Operating mode ON with output capacity in %
• Operating mode Night-time economy mode with setting of sepa-
rate %-wise output capacity for day and night time operation.
• Operating mode Through-flow dependant (disturbance variable)
with %-wise setting of the output capacity
• Operating mode Through-flow dependant (disturbance variabel)
and night-time economy mode with separate %-wise setting of the
output capacity for day and night time operation
The night operation mode is activated by the timers (setting of the tim-
ers in the service menu). The configuration of the output signal for the
dosing pump is made in the configuration menu. The following outputs
can be configured:
• Pulse frequency with optocoupler
• Pulse frequency with relays
• Pulse length with relays
• Constant output 0/4...20 mA
• ON/OFF with relay
ATTENTION!
The night-time economy mode of the flocculant
pump does not depend on the DIN parameters!
