start-up, use and maintenance of the meter. Please have your

staff and any person in charge of the unit read and understand

this manual before starting any work with it. Store this manual

safely in a place where mechanics, installers and other techni-

cal staff as well as operators can rapidly access it in case of

emergency. Pay special warning and provide compliance with all

safety notices in this manual!

1.2 Warnings used in this Operation & Maintenance Manual

This Operation & Maintenance Manual contains vital information

which may endanger people and the unit if they are disregarded.

These statements are identiﬁed by the following symbols:

WARNING!

Refers to a potentially hazardous situation. Non-

compliance can lead to death or extremely serious

injury.

CAUTION!

Refers to a potentially hazardous situation. Non-

compliance can lead to minor injury or property

damage.

IMPORTANT! or NOTICE!

Appears in conjunction with safety instructions

which may endanger the machine and its operation

if disregarded.

IMPORTANT!

Draws attention to supplementary information to

make the work easier and ensure troublefree opera-

tion. Appropriate reference attached directly on the

unit or any of its other parts must absolutely be con-

sidered and held in completely readable condition for

future reference.

1.3 Operators qualiﬁcation and training

Your assembly, operation, maintenance and inspection staff must

be trained and have the appropriate qualiﬁcation for use and op-

eration of the unit. Area of responsibility, tasks and supervision

of the personnel must be provided at all times by the customer.

IMPORTANT!

When free chlorine potentiostatic electrode is used

in a 5-fold input block, it is possible to connect also

a total-chlorine electrode. At the same time bonded

chlorine is calculated by PC and displayed.

Output board (order no. 78399)

On the output block there are 5 integrated relay output and 3

electronic outputs (optocouplers).

The following output can be conﬁgured:

• Controller output free chlorine

with different functions

• Controller output pH value

with different functions

• Controller output bonded chlorine

with different functions

• Controller output conductivity

with different functions

• DIN - contact: Free contact if all conditions of the DIN-

Standards are respected.

• Contact for starting of the ﬂocking pump.

The software conﬁguration automatically assigns these outputs

to the respective terminals in a sequential order- depending on

the conﬁguration of the TOPAXTOPAX®DX:

1. Automatic controller free chlorine

2. Automatic controller pH value

3. Automatic controller bound chlorine

4. Automatic controller conductivity

5. DIN - contact

6. Eco - contact

7. Flocking contact

Depending upon output type, TOPAX®DXselects the next free

relay output or optocoupler. The clamps are assigned in a ﬁrm

order: clamps 87/88 to 95/96 for relays, or 81/82 bis 85/86 for

optocouplers.

NOTICE!

For further information on the terminal connection,

refer to Chapter 4.6

Interface board RS 485 (order no. 78406)

The TOPAX®DX has the option of being ﬁtted with a serial inter-

face RS 485. The RS 485 allows you to transfer data to a PC. The

data communication protocol installed is MODBUS.

With the RS 485 interface it is possible to connect more than one

TOPAX®DX to a network. For this an address is to be assigned

to each TOPAX®DX. In addition to this each TOPAX®DX is ﬁtted

with a computer-interface RS 485.

It is possible to have a maximum of 1000 m of data transfer with

the RS 485 interface. Up to 14 TOPAX®DXs can be connected to

a network with a PC.

An example of a network with more than one device is shown in

chapter 17.

NOTICE!

The data line is to be attached direct to the con-

necting terminals of the TOPAX®DX (clip A and B).

Separate clamping or branching boxes should not be

set. The network address 10 is not permitted.

IMPORTANT!

For the realization of a network with the TOPAX®DX

and the structure of a bus system to a PC a computer

cable "KAT.5 type 2X2XAWG24/1 (Lapp cable)" or

better is to be used.

Using other cables can cause data errors and affect the data

communication. The manufacturer is not liable for this.

Most modern computers are equipped with the serial computer

interface R-S 232 and/or with USB - interfaces. For the connec-

tion to a RS 485 network, an additional connector converter (RS

485 to RS 232 or RS 485 to USB) is necessary.

There are interface components in the under casing part of the

main board in the TOPAX®DX. They are partially hidden from

view by the output components (see diagram 4.6).

NOTICE!

The data line must be locked at both sides with a

120 Ohm line resistance and must be supplied a

ﬁrm potential using the two link plugs on the two

jumpers on the circuit board of the display of all la-

test TOPAX DX versions.

Two link plugs/jumpers have to be connected to the TOPAX®DX

(the last one in the network) for the 120 ohm switch, Pull-up and

Pull-down resistances. The resistances are not active in its deliv-

ered state. The resistance of 120 ohms on the PC side is applied

via the connector converter.

The jumper plug-in slots are located in the upper casing on the

display board, above the ﬂat band-connection to the main board

(see diagram 4.7).
