Overview

General

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

Keypad Input

Labeled Keys

These keys always have the function
indicated by the label, but the
functions
might not be available at all times.
Whether a function is available at a
given time depends on the operating

settings active at that time. Some of
the keys have a second function,
activated by pressing and holding the
key for longer than 2 seconds.

e On/off
