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.

Function of the Service Keys and Switches

A. Menu Access Switch

This switch must be open to work with the service software or configure the A/ D converter (e. g., “Trade” configuration). If the menu access switch is closed, the error message “ACCESS SWITCH LOCKED” is displayed in the service program and the indicator shows “L” (underload) or “H” (overload). In this case, the A/D converter cannot be configured. If adjustment is necessary (span, linearity), the “± 2%” window is active.

B. SBI/BPI Key

To use the Sartocas program (v 1.46 or later) or Psion server (v 4.10 or later). the Combics indicator must be in BPI (binary processor interface) mode (for example, to load a modified data record from the A/D converter into its controller). This setting is valid for the COM1 port.

Note: To perform adjustment

only with the service software, the COM1 interface is set to the xBPI (eXtended Binary Processor Interface) protocol and the laptop or Psion server connected to that port.

Calibration/Adjustment Routines in Service Mode (General Information)

There are three ways to adjust the span: – Using external weights – By entering the specifications of the load cell(s) (sensitivity in mV/V) – By entering geographical data (latitude and altitude of the place of use) or by

entering the acceleration of gravity (at the place of use)

Span adjustment with external weights always takes precedence.

What does this mean when performing service work?

If a weighing system is used in a location other than that for which it was originally intended (i.e., the geographical data at the new place of use does not match the entered at Sartorius AG in Goettingen, Germany), the scale span can be adjusted by using external weights or by entering the specifications of the load cell(s). In this case, the geographical data entered for the original place of use is no longer valid. The same applies for span adjustment performed after any repair work on the weighing system. Once you store the geographical data or acceleration of gravity at the place of use and subsequently perform span adjustment using weights, the scale is correctly programmed and adjusted. You can now enter the geographical data of the new place of use to adapt the scale for use at that location.

If the acceleration of gravity has been entered, this data takes precedence over any geographical data (latitude and altitude) previously entered.

Valid Locations for Use

Once the exact geographical data or the acceleration of gravity has been entered and subsequent span adjustment performed, a scale with a resolution of 3000 digits can be used within a tolerance zone of ±100 km from the latitude entered and ±200 m from the altitude. The same applies when the acceleration of gravity is entered.

The following values are entered when the Combics scale is adjusted in Goettingen, Germany: – Latitude: 51.53 degrees (= 51° 32’) – Altitude: 151 m – or the corresponding acceleration of gravity, 9.811590 m/s-2

The greater the precision of the geographical data entered, the greater the precision achieved with the weighing instrument; the tolerance range, however, is restricted accordingly (see above).

Zone “D”

For a complete scale used in the Federal Republic of Germany, the following data can be entered for scales with a resolution of 3000 digits at the place of span adjustment:

– Latitude: 51.00 degrees – Altitude: 513 m – or the corresponding acceleration of gravity, 9.810 m/s

-2

The area of use valid for this scale is designated “Zone D” (valid only in Germany).

Menu Item 1-20: Entering the Geographical Latitude and Altitude, or the Acceleration of Gravity

When you activate menu item 1-20-1, the value 99999.99 is displayed; under 1-20-2, is 9999999 displayed too. Otherwise, if values have already been entered for geographical latitude and altitude, then 0.000000 is displayed under menu item 1-20-3. During calibration, the Combics show will whether and which gravimetric data (geographical latitude and altitude, or acceleration of gravity) is used, if the menu item 8-12-2 is activated.

If latitude and altitude are used, the display shows “Altitude” for 2 seconds when the calibration procedure is started (CAL), followed by the configured elevation above sea level in meters. Press ) to confirm this information. Next, the display shows “LATITUDE” for 2 seconds, followed by the value set for the geographical latitude (in degrees). Press ) to confirm this information. The calibration weight is now prompted. If the acceleration of gravity is given rather than the geographical latitude and elevation, the display shows “GRAVITY” for 2 seconds (after “CAL”), followed by the value entered for the local acceleration of gravity. Press ) to confirm this information.

However, if the calibration weight is prompted as soon as the “CAL” display goes out, this means whether the correction of the calibration factor has been deactivated nor the menu item 8-12-2 is activated; in other words, neither the geographical latitude and altitude nor the acceleration of gravity have been entered under menu line 1-20.

Entering the Place of Adjustment with Subsequent Adjustment (Example)

Configuring the A/D Converter in the Combics Indicator (Service Mode)

The A/D converter must be configured in the following cases:

– To adapt the existing configuration to customer requirements (for example,

to change the nominal capacity or the resolution). – To adapt the Combics for use with any commercially available strain-gauge

load cell or analog Sartorius CAPP or CAPS weighing platform, when installing

a new system. – After replacing the electronic A/D converter during repair work, also on

combics scales, when the Sartocas software is not used.

Menu Item 11: A/D Converter Settings (Configuration: Standard, Trade)

Note: Before the A/D converter can be configured, you need to load either the

“Standard” configuration or the “Trade” configuration, depending on customer requirements.

– 9-1-3: Load “Standard” configuration – 9-1-4: Load “Trade” configuration

Menu Item 11: A/D Converter Configuration (General Information)

Note: Access is restricted by a special password.

Features With the menu access switch open, you can

configure most of the parameters affecting the following specifications:

– Toggling between Standard and Trade configurations

(for use in legal metrology)

– Verification scale interval e – Scale interval d – Minimum load – Maximum load – Maximum load for a given range – Verification scale interval e for a given range

– User-definable weight units

These parameters are not reset when you restore the factory defaults in the operating menu. Parameters not listed above are not affected by your choice of Standard or Trade configuration; the same restrictions apply as for Sartorius weighing instruments which cannot be configured.

Note on A/D Converter Configuration

A/D converter configuration is performed using the numeric menu (weighing platform 1).

Important: The A/D converter can be configured only in

the service mode.

The maximum load for each weighing range must be entered in an appropriate weight unit. Select the desired weight unit for operation under menu line 11-7, “Weight units”. The maximum load for each range must be a value that can be displayed in any available weight unit. Weight units that are accessible (or blocked) for use as Weight unit 1 are also available (or blocked) for use as Weight unit 2. The weight unit used for the configuration cannot be blocked.

Checking and Configuring the Equipment for Use in Legal Metrology:

Following A/D converter configuration, write the metrological data on a tag for all weighing ranges. Afterwards, affix the enclosed protective acetate overlay to the tag.

After completing calibration and adjustment, move the menu access switch back to the “closed” position and then turn the Combics indicator off and back on again to activate the new configuration.

Open menu line 1-7 to make sure only the permitted weight units are accessible.

Perform necessary routines for scales used in legal metrology.

Descriptions of the Individual Menu Items

Menu Item 9-1-3 / 9-1-4: Selecting and loading configuration data

Before selecting the menu item for A/D converter configuration, check whether the weighing platform is used in the standard operating mode (Standard configuration) or in legal metrology (Trade configuration):

– Standard Configuration

(menu item 9-1-3) or

– Trade Configuration

(menu item 9-1-4)

Menu Line 11-1 (Accuracy Class) This menu line is not shown when the Standard configuration is active.

When the Trade configuration is active (for verifiable or verified weighing platforms), only menu item 11-1-4 is shown. Select the accuracy class appropriate for the weighing platform connected. Which class is appropriate depends

on the load cell(s) installed.

In legal metrology, only classes l (menu item 11-1-4) can be selected. Press k to select the accuracy classes and ) to confirm. A circle (o) after the menu code indicates the active setting.

Selecting the Weighing Range Structure (Menu Item 11-3)

The capacity of the weighing platform can be divided into multiple ranges. These settings are configured under menu item 11-3:

Single-range Scale (11-3-1) The entire weighing range is divided into scale intervals on the basis of the lowest interval d and the maximum load. In this case, the readability over the entire weighing range is always the lowest scale interval d.

Multiple-range Scale (11-3-3) A multiple-range scale has two weighing ranges. When the maximum capacity of the lower range is exceeded, the scale switches to the higher range (lower resolution) and remains in that range. The scale can be returned to the lower weighing range (higher resolution) only by unloading the scale and then pressing the ( key.

Scale Interval d

The lowest scale interval d indicates the resolution of the weighing instrument. The scale interval d can be entered only in increments of 1, 2, 5, 10, 20, 50, etc. When working on a verifiable or verified scale in accuracy class l, you are not prompted to enter the lowest scale interval, as this is equal to the verification scale interval e.

Verification Scale Interval e

The verification scale interval e indicates the resolution of the weighing instrument in legal metrology. When accuracy class l is active, this is equal to the scale interval d. Thus with classes l, the lowest scale interval d is not prompted.

Range 1, Range 2, Range 3

Here you can enter the limits for each of the weighing ranges. When a limit is exceeded, the accuracy changes. The following applies when entering range limits: Range 1 < range 2 < range 3 < maximum capacity. Thus the weighing capacity can be divided into 4 ranges. The resolution changes in intervals of 1, 2, 5, 10, 20, 50, etc. The lowest resolution is equal to the specified lowest scale interval d. Set unused ranges to 0.

Maximum Capacity

The maximum capacity is the maximum load that may be placed on the weighing instrument. If a heavier load is placed on the platform, the display shows H. The scale intervals are derived from the maximum load and the lowest scale interval d. In legal metrology, the number of intervals must not exceed 6000 e, or 3000 e per range in a multi-interval scale. In standard operation, as opposed to legal metrology, you can define a “SuperRange” weighing instrument with more intervals. For example, a maximum load of 60,000 lb with a lowest scale interval d of 0.001 lb 60,000 scale intervals. These parameters, however, may be influenced by physical restrictions.

Available Weight Units (Menu Item 11-7)

With this function, you can make particular weight units inaccessible during weighing. Available units are indicated by a circle (o) on the display (more than one can be selected).

Calibration/Adjustment Unit (Menu Item 11-8)

This setting defines the weight unit with which calibration must be performed. The calibration unit remains the same, even when a different weight unit is used during normal weighing operation.

Calibration without Weights (Menu Item 1-19)

The values entered for nominal capacity (in lb; menu item 1-19-1; specification of the strain-gauge system), resolution in kg; (menu item 1-19-2) and sensitivity in mV/ V menu item 1-19-3) are converted to internal quantities. Once the A/D converter configuration data has been stored, these parameters can no longer be read. For weighing platforms with multiple load cells, enter the sensitivities of the other load cells under menu items 119-4 (cell 2) through 1-19-6 (cell 4). Select menu item 1-19-7 to store the data entered.

Important: Calibration without weights cannot be

performed on weighing instruments used in legal metrology.

Storing Configuration Data (Menu Item 11-10)

Select menu item 11-10-1 to store the A/D converter configuration data.

Once these parameters have been configured, the A/D converter in conjunction with the load cell is defined as a weighing instrument. The A/D converter, in conjunction with the weighing platform, can now be used like any standard weighing platform.

In addition, the weight unit must be defined and the weighing platform adjusted (calibration/adjustment and linearization must be performed). For a detailed description of these procedures, see the chapter entitled “Calibration/Adjustment in Service Mode”.

Important: After configuring the A/D converter

and adjusting the weighing instrument (calibration/adjustment and linearization), return the menu access switch to the “closed” position (i.e. for use in legal metrology). Turn the Combics indicator off and then on again (key sequence: e e to activate the new configuration.

Once the A/D converter configuration has been locked (menu access switch closed), the indicator can no longer be used to influence weighing results. The scope of functions available in the weighing instrument is defined by the A/D converter. Scale functions which can be activated are, for example: weight readout, taring, adjustment, reading tare value, saving/deleting tare values.

Repairing the Combics Indicator

Important: An isolating transformer must be installed between the indicator and mains

before performing work that entails opening the Combics indicator housing.

To open the Combics indicator, remove the four nuts as shown in the illustration on the left.

Note: After completing maintenance or repair work, check the seal between the

front panel and the housing body for damage and replace if necessary.

If the Combics indicator in question has an IP67 protection rating,

a special test procedure is used to check the IP67 protection after the housing has been closed.

Replacing the Front Panel

In the case of a defective keypad overlay, keys, LEDs, or display, the entire front panel must be replaced.

combics_10.eps

Blank Display

If the display is blank (dark), disconnect the equipment from mains, open the housing and disconnect all cables and wires from the subassemblies. Then connect the equipment to power again through an isolating transformer and connect all subassemblies again, measuring the supply voltage in each case.

– The voltage at the power supply output (connector A; see page 71) is

15V ± 0.3 V direct current. – The output voltages of the DC/DC converter are listed on page 72.

Replacing the Power Cable

– Disconnect the cable from the power source.

– After replacing the power cable, use a torque wrench to tighten the cable gland

to 3 Nm.

pg_netz.jpg

Replacing the Power PCB

– Disconnect the cable from the power source.

– Pry the protective cap from the power PCB.

To do this, insert the end of a slotted-head screwdriver into each of the

four openings on the protective cap and carefully push the retainer clips,

located further down, to one side.

– Remove the protective cap and disconnect the two wires (blue/brown).

– Unplug connector A, remove the 2 screws and replace the power supply.

After replaceing the PCB, make sure to return the protective cap to its

original position.

Replacing the DC/DC Converter

Note: Use a digital voltmeter (DC setting) to measure voltages against ground (earth).

No particular points of measurement are defined for this procedure; for this reason, use a thin test pin and exercise extreme caution to avoid short-circuiting the equipment.

The various supply voltages delivered by the DC/DC converter can be measured at the following points. M 1: 13V ± 1.3V Supply voltage for a connected printer. M 2: 15V ± 0.3V Input voltage for the DC/DC converter. M 3: –29V ± 1.5V Supply voltage for the front panel electronics. M 4: –8.5V ± 0.2V Supply voltage for the A/D converter M 5: 8.5V ± 0.2V Supply voltage for the A/D converter M 6: 5V ± 0.13V Supply voltage for the digital PCB

Replacing the A/D Converter

– Before replacing the A/D converter, try to read out the data from the A/D

converter’s controller using the service software; if this is successful, you can

load the adjustment data in the controller of the new A/D converter once it is

installed. In many cases, this precludes the need to adjust the weighing system.

– Because the model designation and serial number are not stored in the A/D

converter’s controller, you do not need to enter this data again after replacing

the A/D converter. – When connecting the weighing platform (load cell(s)) to the A/D converter,

it is important to install a ferrite ring over the signal lines leading from the

platform, to ensure electromagnetic compatibility.

1. Disconnect the platform measuring voltage lines from the terminal strip (pins 3 and 4) in the A/D converter. Then short circuit these two lines and connect them to pin 7 (GND) of the terminal connector. If the A/D converter is intact, the weight readout should be stable. Disconnect the cable from the platform.

2. Connect the strain-gauge simulator and turn the switch to simulate different input signals. The weight readout should be stable.

Replacing the Digital PCB

Note: If communcation problems occur during communication with connected devices

(such as a printer), check the cable connections and the data transfer parameters first; if the error source is not found, start the internal test program.

– Turn off the indicator. – Press and hold the k key and turn the indicator on again. The test program

starts.

In case of defect, replace the digital PCB.

Some Combics indicators are equipped with D-Sub 25 female connectors, and some with cable glands; make sure you order the correct PCB for your indicator (see the illustration on the left).

– After replacing the digital PCB, use the PPLoader program to load the

application software, if necessary.

– Afterwards, enter the model designation and the Serial number of the Combics

scale (see pages 65 and 67).

Adjusting the Weighing Platform

Adjusting the Off-center Load

If the weighing platform has only one load cell, the off-center load is not adjusted in case of error; rather, the load cell must be replaced. The off-center load is adjusted only in weighing platforms that have four load cells.

Procedure (Example Illustrated on the Left)

– Place the test weight (1000 lb) on the weighing platform and write down the

weight values measured.

– The load cell with the lowest weight value (9972 lb) is the reference load cell.

This load cell does not require adjustment.

– Calculate the difference between the weight value registered by this load cell

and those registered by the other load cells.

– Plot the point of intersection of the calculated off-center load difference

(x-axis) and the test weight (see page 77).

– The adjustment resistance (total) and the best resistor combination can be read

from the y-axis (see the diagram on page 77).

In the example given here, load cell 3 has an off-center loading error of 8 lb,

which yields an adjustment resistance of 1.5 ohm + 0.82 ohm.

– Depending on the resistor combinations of each individual load cell, the

required resistors are activated by disconnecting the corresponding “0-ohm resistor” (see page 78).

Note: The resistance values detected are based on 350-ohm load cells.

For 700-ohm load cells, double the resistance values.

Off-center Load Adjustment: 0-ohm Resistors (Example)

In the example given on page 75, the two 0-ohm resistors (marked by a white dot) must be removed. This activates the adjustment resistors (0.82 and 1.5 ohms). Follow the same procedure to determine the resistance values for load cells 1 and 2, and remove the 0-ohm resistors if necessary.

The allocation of load cells in the weighing platform to contact on the adjustment PCB can be determined by checking the wiring in the weighing platform.

Note: On stainless steel models, the IP67 protection must be checked after closing the

junction box.

Repairing the Weighing Platforms

Replacing the Connecting Cable

If the connecting cable (from junction box to Combics indicator) needs to be replaced on a weighing platform with four load cells, or if the load cell needs to be replaced on a platform with only one load cell , open the Combics indicator and disconnect the cable from the terminal strip of the A/D converter. Unscrew the cable gland; the cable or load cell can now be replaced.

Remove the isolation and connect the new cable: – Expose approx. 6 cm (2.4 in.) of the wires (3) in the cable. – Remove the isolation from approx. 1 cm (0.5 in.) of the wires and affix ferrules

to the wire ends. – Thread the cable through the cable gland. – The shielding (1) must have contact with the clamps (2). Connection to ground

via the shield. – Make sure you install the required ferrite ring (see page 73).

– After replacing the cable or load cell, use a torque wrench to tighten the cable

gland to 5 Nm.

Note: On stainless steel models, the IP67 protection must be checked after

closing the junction box.

Replacing Load Cells

If an off-center load error is detected (platforms with one load cell), or if the output signal from the load cell is too high or too low (InF 02 is displayed during span adjustment), replace the load cell.

Because the mechanical construction of the platforms is basically uncomplicated, no detailed description of the disassembly procedure is included here.

Important:

– When replacing load cells in a weighing platform with four load cells, lift the

corner using an M16x120 threaded rod to access the cells.

The threaded rod can be obtained from a specialized supplier.

– When reassembling the weighing platform, make sure to replace any plates that

were under the platform frame.

– When replacing a load cell designated “GWT Type 011275/500 C3”, the three

bushings (two for affixing the load cell; one for the load cell base) must be

removed from the defective load cell and installed in the new load cell. These

bushings are located in bore holes in the load cell.

lastz_1.jpg

eckl_5.jpg

– When installing the new load cell, make sure any arrow (see the illustration on

the left) always points in the movement of the load cell. – Tighten the load cells with the required torque.

Torque Values

– After replacing load cells, you need to check the overload stops and adjust

them if necessary (see page 77-80).
