Overview

General Information

Service Concept

Prerequisites for performing maintenance and repair work on Sartorius Midrics
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.

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

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

Information

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

indicator and the power supply before performing work that entails opening
the Midrics indicator housing.

On complete Midrics scales, check and adjust as necessary:

– Repeatability (standard deviation)
– Off-center load
– Span
– Linearity

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

5

Overview of the Models

The hardware configuration consists of either a Midrics 1 or 2 indicator and
Sartorius weighing platform(s), or a Midrics 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 complete Midrics 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 Midrics scales from Sartorius are primarily used in industry. Because there are a number of hardware
configurations to choose from, Midrics models are constructed according to customer requirements.

The complete Midrics scale consists of:

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

The Midrics 1 / 2 indicators consist of:

– Front panel with keypad and

digital display (Midrics 2 has
additional keys)

– Midrics indicators

are equipped with either cable
glands or D-Sub 25 connectors.

Note: Additional electronic subassemblies are optional.

Function of the Switches

This switch must be open to work with the service software or to 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.

Repairing the Midrics Indicator

Indicator

Important:

An isolating transformer must be installed between the indicator
and mains before performing work that entails opening the Midrics
indicator housing.

To open the Midrics 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 Midrics indicator in question has an IP65 protection rating,
a special test procedure is used to check the IP65 protection after the
housing has been closed.

Mi171107.eps

10

Replacing the Front Panel

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

There are two front panel variants, Midrics 1
and Midrics 2. The only difference between
the two is the range of operating keys.

If the indicator housing seal is defective, it
must be replaced. When installing a new
seal, make sure it rests entirely within the
housing and is not caught between the
upper and lower housing parts when you
close the indicator.

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 12) is

15V ± 0.3 V direct current.

– The output voltages of the DC/DC converter are listed on page 13.

Replacing the Power Cable

– Disconnect the cable from the power source.

– Open the housing.
– Replace the cable

Note:

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

Points of Measurement

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: 15 V ± 5% Input voltage for the DC/DC converter.
M 2: –9.2 V ± 5% Supply voltage for the A/D converter
M 3: +9.2 V ± 5% Supply voltage for the A/D converter
M 4: 5 V ± 5% Supply voltage for the digital PCB
M 5: 3.3 V ± 5% Supply voltage

Replacing the Main PCB

– Before replacing the main PCB, try to read out the data from the main PCB

controller using the service software; if this is successful, you can load the
adjustment data in the controller of the new main PCB once it is installed. In
many cases, this precludes the need to adjust the weighing system.

Procedure for Off-center Load Adjustment

Proceed as follows to adjust the off-center load using the junction box:

– Stand the weighing platform (with 4 load cells) on its side and secure it in this

position.

– Remove the four screws (S) from the junction box.

– Pull approximately 20 to 30 cm of the load cell cables out of the platform (see

arrow).

– Return the weighing platform to the horizontal and position it next to the

junction box.

– The junction box is now accessible for adjustment of the resistors.

– At the conclusion of off-center load adjustment, follow the instructions above

in reverse order to reassemble the weighing platform.

Important:

Make sure to push the cables back into the weighing platform.

Adjusting the Off-center Load

If the weighing platform has only 1 load cell, the off-center load is not adjusted in
case of error. The load cell must be replaced.

The off-center load is adjusted only in weighing platforms that have 4 load cells.
Mechanical asymmetries can result in off-center loading errors that exceed
permissible tolerance limits. Such errors must be compensated by soldering resistors
to the PCB in the junction box.

The 4 solder bridges for the resistors are short-circuited at the factory (see the
illustration on the left; note the 4 solder bridges and the sequence of the load cells).

Note: The off-center load is adjusted only in weighing platforms that have 4 load

cells.

The 4 solder bridges for the resistors are short-circuited at the factory (see the
illustration on the left; note the 4 solder bridges and the sequence of the load cells).

To minimize the off-center loading error, use the load cell with the lowest readout
value as a reference. Then adjust the other load cells to this value by adding
resistors.

Repairing the Weighing Platforms

Replacing the Connecting Cable

If the connecting cable (from junction box to

Midrics 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 Midrics 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.

– 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:

To replace a load cell in a platform with four load cells, use two eye bolts

(6740-81) in two corners and then lift the weighing platform. Remove
the plastic caps from the bore holes before inserting the eye bolts.

The eye bolts can be ordered under spare part number 6740-81.

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

were under the platform frame.

Determining the Resistance for Adjustment of the Off-center Load

Determining Resistance Values

- Place the test weight on each load cell in turn and write down each displayed
value.

- Using the lowest displayed value as the basis, calculated the resistance values
for the other load cells in accordance with the following equation:

Equation:Equation:

R = required resistance (in ohms)

RR

RR

R(0) = Initial resistance in the load cell being adjusted (in ohms), (if not specified

in the specification sheet) measured between Signal + (OUT_POS, positive
measuring voltage) and Signal - (OUT_NEG, negative measuring voltage).

GG

GG

G(D) = Difference between lowest off-center loading error (from reference load

cell) and the off-center load value displayed for the weigh cell (in kg).

GG

GG

G(T) = Test weight applied (in kg)

- Solder the required resistor into the bridge of the load cell being adjusted.

- Then perform calibration/adjustment again.

Adjusting the Weighing Platform

Sample Calculation Based on Diagram 2

Initial resistance in the load cell: 1000 ohms.

- Test weight: 500 kg

- Readout for reference load cell = 498 kg (load cell with the lowest readout
value).

- Readout for load cell being adjusted = 501.1 kg

-

GG

GG

G(D) = 2.3 kg

RR

RR

R = R(0) x G(D)

RR

RR

R = 1000 ohms x 2.3 kg

RR

RR

R = 4.6 ohms

G(T) 500 kg

In this example, note that the test weight (500 kg) is also distributed over the
other load cells, which means that the weight on the load cell being tested is
somewhat lighter. To compensate for this effect, always use the next higher
resistor value.

R = 4.7 ohmsR = 4.7 ohms

R = 4.7 ohmsR = 4.7 ohms

R = 4.7 ohms ((resistor to be installed (see page 42)).
