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.

On Combics scales, check and adjust as necessary:

(The procedure is the same as for all scale and weighing platform models.)

– Repeatability (standard deviation)

– Off-center load

– Span

– Linearity

When to Use Which Procedure

Combics Indicators

Activate the service mode to perform all adjustments See page 17

Important: All adjustments required after repair work (such as

replacement of the A/D converter or the load cells) are

performed using the terminal.

The Sartocas service software is not required for these adjustments.

Using this software, however, can make some adjustments

unnecessary (see „Use Sartocas software“ below).

Activate the BPI mode to load a modified data record in the controller

of the A/D converter See page 15

Activate the xBPI protocal to perform calibration and adjustment, if necessary See page 16

using Sartocas

Use Sartocas software - to reactivate the SBI protocol by selecting the „Close“

command on the Combics terminal (or by restoring

factory defaults (menu line 9-1)

- to program a new A/D converter PCB with data read from the old PCB

The necessary adjustments and customer specific menu settings

are not necessary

Use PPLoader software to update the application software in the terminal

Drift, display

Inf 02 when starting an

adjustment routine to check the A/D converter (quick-test) See page 73

or with the strain-gauge simulator,

check load cell(s) with the load cell tester

Display blank (dark) Disconnect the equipment from the power supply and

disconnect all cables and wires from the subassemblies,

connect equipment to power again, connect subassemblies

in turn and measure voltages See pages 70-72

No communication with

connected equipment Check connections and data transfer parameters;

start internal test program; if necessary, replace

Overview of the Models

The hardware configuration consists of either a Combics 1 or 2 indicator and

Sartorius weighing platform(s), or a Combics 1 or 2 indicator and weighing

platform(s) (strain-gauge load cells) from another manufacturer.

Important: Mechanical and electrical service or repair work on the 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.
