vided. The tray of reagents has an outlet where spilled liquids can be

drained off.

Reagents Depending on the analyzer module, various reagents are required for

the operation of the TresCon UNO:

 Standard solutions

 Cleaning solution

 Other reagents

The reagents are supplied to the analyzer module via tubes.

Reagent containers The tube connections of the reagent containers are also color coded so

that the tubing can be connected without any problem. The colors cor-

respond to the reagents connections on the analyzer module. This ena-

bles the reagents to be uniquely assigned.

1.2.3 Enclosure

The enclosure of the TresCon UNO consists of a robust synthetic

material. It has a large lockable door on the front. It is opened to switch

the instrument on or off, to operate the controller and to do mainte-

nance work.

The door has a transparent pane so that the measured value can be

read on the outside of the controller and the analyzer module can be

observed during the operation.

The enclosure has the following openings/lead-in ducts on the under-

side:

 Drillings to lead in the reagent tubes

 Cable glands for relay connection cable, valve control line, interface

cable etc.

 Lead-in duct for power cable

 Drain drilling for reagents

gram

The display mode allows you to display one

or more measured values for daily, weekly or

monthly periods of time as graphs on the dis-

play or to output them via an external printer.

Data storage The display of one or more measured values

for the last four weeks in the form of a list.

The values can also be output to an external

printer.

Overview TresCon UNO

ba43134e08 05/2017

In addition, the measured values can be forwarded to external devices

(e.g. recorder, PC) via the interfaces (RS232, RS485, modem, 20 mA

recorder output).

Record The comprehensive record functions enable

data records to be compiled (analyzer

module-related, time-dependent, etc...) and

the corresponding interval to be individually

optimized.

Report The report function enables the limiting con-

ditions and operating states to be traced in

case of malfunction. This makes trouble-

shooting easier. The instrument configura-

tion can be optimally adapted to individual

operating conditions.
