Overview

Service Concept

Prerequisites for performing maintenance and repair work on Sartorius Combics

scales requires considerable experience with both indicators and weighing

platforms.

In case of defects, repairs are performed on site. Generally, the equipment is not

replaced.

General Information

– Do not connect or disconnect cables to or from the equipment; always

disconnect the power cable from the wall socket (mains supply) first!

– To ensure safety, an isolating transformer must be installed between the

indicator and the power supply before performing work that entails opening

the Combics indicator housing.

Important: Mechanical and electrical service or repair work on the complete Combics scale

requires considerable experience, and for this reason should be performed only

by Sartorius technicians trained at the factory. Any attempt to perform repair

work can result in damage to the equipment.

Description of the Equipment

The complete Combics scales from Sartorius are primarily used in industry. Because there are a number of hardware

configurations to choose from, Combics models are constructed according to customer requirements.

The complete Combics scale consists of:

– A choice of weighing platforms with capacities from 3 kg to 3000 kg (in stainless steel or steel) and indicators

The Combics 3-indicators consist of:

– Front panel with keypad and

digital display (Combics 2 has

additional keys and LEDs)

– Combics indicators

are equipped with either cable

glands or D-Sub 25

connectors.

Note: Additional electronic subassemblies are optional.

Operating Design

With Combics 3 you can

– collect weight values from two

weighing platforms

– use application programs to

calculate and display results

– assign codes to identify the

samples weighed

Before you begin, you need to

configure your Combics complete

scale for your requirements. This is

achieved by setting parameters in the

operating menu (for example, to

configure a connected printer). You

can then begin operation, with

functions active for storing and

calculating weighing data.

The description of the operating

design is divided into the following

sections:

– Data Input

– Display Modes

– Error Codes

– Data Output

– Saving Data

Data Input

There are a number of options for

entering data:

– Through the indicator keypad (e.g.,

with the 0, 1, 2... 9keys)

– Through the weighing platform

(e.g., tare values)

– Through the digital input |output

interface

– Through the COM port

– Through a bar code scanner or

external keyboard
