General Information

QC scales come in different model series, each with different housing versions.

The QC7CCE... series comes in the “QS-Mini” housing version and the

QC34EDE... and QC64EDE... series in the “QS-Maxi” version.

The strain gauge Systems are different in these models.

The electronics are the same in all of these models (MC1), i.e., the operating instructions, scale operating menu and error codes are the same for each model.

The -S0UR versions are equipped with a different keyboard foil compared to the standard versions (for american users).

SARTORIUS QC - Scales

Activating the BPI Mode

In order to use CAS programs with the MC1 server or a personal computer, the scale must be set to the BPI mode.

Disconnect the AC adapter from the scale and open the display unit by removing the 4 screws at the back.

Carefully pull the front panel with the main PCB far enough away from the rear panel to access the BPI switch (see illustration at left).

Reconnect the AC adapter and switch on the scale by pressing e.

Once 0.0g is displayed, move the BPI switch to the right.

The segment check is now displayed periodically. Wait until the segment check has lit up at least 3 times; the scale is now in the BPI mode.

Move the switch back to the original position; the scale now shows the normal weighing display.

Close the display unit.

You can now operate the scale in conjunction with the Sartorius MC1 server in the BPI mode.

After working in the BPI mode, make sure to set the write-protect again (with the Sartorius MC1 server: “close”), so that the QC scale returns to the standard data output protocol (SBI mode).

Otherwise you will not be able to transfer data to a peripheral device; if you press the print key, the error code “Err30” will be displayed.

This function switch has no effect on service operations, but you need to make sure that it is always in the correct position, i.e., set to the left (see illustration).

Overload Stops

1. QC7CCE-S

Adjusting the Lower Middle Stops

The lower middle stop cannot be seen while you are adjusting it; thus you need to go by sound in checking and finding the correct position.

– Place the scale on a stable surface, so that you can reach both stop screws (113) from underneath the scale.

– Place a load equal to the maximum capacity of the scale plus 1 kg on the middle of the weighing pan.

– Unscrew the stop screws (113) until you can hear that the stop is free.

– Turn one of the screws (113) slowly against the stop while checking the distance by pressing down on the load.

– Continue this procedure until you have found the position in which the screw (113) touches the stop (the sound of the stop can no longer be heard).

After setting the first screw correctly, turn it back by ¼ turn in order to adjust the second screw.

- Follow the same procedure to adjust the second screw (113).

- After the second stop screw (113) is in the correct position, readjust the first screw by ¼ turn so that it is back in the correct position as well.

- Once both screws (113) are adjusted properly, remove the scale from its raised position.

12

SARTORIUS QC - Scales

Adjusting the Upper Middle Stop

– Remove the weighing pan.

– There must not be any load on the scale when the upper middle stop is being adjusted.

– Adjust the upper middle stop so that the gap between the weighing pan and the stop is 0.6 mm (tolerance range: + 0.1 mm); check the gap size with a feeler gauge.

– When the gap is correct, place the weighing pan on the scale.

Adjusting the Corner Stops

– Remove the weighing pan and place it upside down on the scale.

– Place a load equal to the maximum capacity in Position 1 on the weighing pan.

– Use a feeler gauge to check the distance between the corner stop screws

(115) and the weighing pan.

– Proceed as in the following example to adjust the corner stops:

– The actual value of the gap (as determined with the feeler gauge) is

1mm.

– The target value is 0.25 mm.

– The deviation (actual minus target value) is, in this example, 0.75mm.

– The lead of the stop screws is 1 mm, i.e.:

1 turn clockwise increases the gap by 1 mm

1 turn counter-clockwise decreases the gap by 1 mm

– The adjustment step is calculated from the above values:

1 turn of the stop screw changes the gap size by 1 mm, i.e. in the above example, you would need to turn the screw ¾ of a turn counter clockwise to achieve the required adjustment (deviation: 0.75 mm).

– Before adjusting the screws (115), remove the weighing pan from the scale.

– Proceed in the same manner to adjust the corner stops in positions 2 – 4.

– After completing this adjustment procedure, place the weighing pan right side up on the scale.

– When you have finished adjusting the corner stops, proceed to the adjustment/calibration functions.

2.

QC34EDE-S, QC64EDE-S

The models QC34EDE-S and QC64EDE-S have two overload-protection features.

The first overload stop is in the pan support, accessible from beneath the scale. This is an adjustable set screw, fixed by a locknut.

Adjustment:

– Remove any load from the scale.

– Place the scale on 4 blocks of equal height in order to make the bottom of the scale easily accessible, since the set screw is only accessible from the bottom.

– Place a load on the scale, on the front of the weighing pan, equal to the following weight:

QC34EDE-S

QC64EDE-S

40kg

70kg

– Carefully turn the set screw until it just touches the System, and then attach the locknut.

– Check your adjustment by placing the maximum load on the scale

(QC34... 34kg; QC 64... 64kg) - the set screw must be free and the weight displayed.

Adjusting the Second Overload Stop Feature:

The second overload protection device consists of four hex nuts, located in the base pan of the scale and accessible from below. You can adjust the height of these hex nuts with a 13 mm wrench.

– Unload the scale and turn it over.

– Place a load on the first corner (see illustration):

QC34...: 20kg

QC64...: 40kg

Adjust the height of the hex nut until a slight overload (QC34...: +2kg;

QC64...: +5kg) causes the base pan to rest on the screw (displayed value no longer changes).

Repeat this procedure on all 4 corners.

SARTORIUS QC - Scales

Zero Point Offset Value

The zero point offset value must be adjusted in order to adapt the bridge voltage of the strain gauge System to the working range of the scale’s electronics. You may need to adjust this value:

after replacing the strain gauge system

after replacing the main PCB

if the scale’s span (sensitivity) cannot be adjusted (not even with the

PSION server) and the error code “Err02” is generated

if the zero point offset voltage has changed and lies outside the tolerance range, e.g., if the strain gauge System becomes “warped”

Adjusting the Zero Point Offset Value

The are two ways of adjusting the zero point offset value:

1. using a digital voltmeter

2. using the PSION server, Datapack version 4.4 and newer

1. Adjustment using a digital voltmeter:

Open the display unit by removing the 4 screws at the back.

Reconnect the scale to AC power.

With no load on the weighing pan, use the digital voltmeter to measure to ground on R122 (OP output IC 20 / pin 6).

The zero point offset voltage should be between - 300 mV and - 2V.

If the zero point offset voltage lies outside these limits, you can adjust it by changing the following solder bridges on the main PCB.

Adjustment using the PSION server

– Switch the scale to the BPI mode (see page 11).

– Switch on the PSION server and call the CAS program (version 4.4 or newer)

– Select the menu item “Electr-zero-point” from the “Diagnosis” submenu

– With no load on the weighing pan, a value of 14.8 % ±11% should appear in the PSION display.

If the value displayed is outside the tolerance limits, you can adjust this voltage by changing the solder bridges LB7 and LB8.

LB7/LB8

2 / 2 open open

After adjusting the zero point offset, proceed with the adjustment of the span

(sesitivity) (with the PSION server, if desired).

Adjusting the Linearity

There are two methods for adjusting the linearity:

1. As described in this manual, or

2. Using the MC1 PSION server

– Test the linearity of the scale in 1000g steps over the entire weighing range.

– If any deviation is greater than the tolerance values given, you need to adjust the linearity.

– Set the code “1 9 5” in the scale operating menu (external linearization accessible).

– When 0.0g is displayed, press the e key and hold it for about 3 seconds; then release it.

– The first linearization value is displayed.

– Place the prompted weight on the middle of the weighing pan.

– After the weight is stored, the next weight value is displayed.

– Each linearity support point is called and stored.

– When this routine ends, the scale returns to the normal operating mode.

– If desired, reset the menu item “1 9 “ to the standard setting.

After linearization, make sure you perform the adjustment of the span

(sensitivity).

SARTORIUS QC - Scales

Adjusting the Span (Sensitivity)

There are two methods for adjusting the span (sensitivity):

1. As described in this manual, or

2. Using the MC1 PSION server

– Set the code “1 9 1” in the scale operating menu (external calibration accessible).

– When 0.0g is displayed, press and hold the e key for about 3 seconds; then release it.

– The adjustment weight is displayed.

The scale will only accept an adjustment weight that is within a tolerance of

2% of the target value. Any greater deviation can only be adjusted using the

MC1 PSION server (Datapack version 4.4).

– Place the prompted adjustment weight on the middle of the weighing pan.

After confirming the weight, the scale returns to the normal operating mode.

Replacing the Main PCB

In the case of defects, do not attempt to make any repairs at the component level, but rather replace the entire subassembly.

Before replacing the main PCB, read out and store the scale’s data records using the MC1 PSION server, if possible.

If this is not possible, order a replacement PCB; make sure you supply the model and serial number of the scale for programming purposes.

– Open the display unit by removing the 4 screws at the back.

– Carefully pull the front panel far enough away from the rear panel to disconnect the 3 cables (data output, power supply and connecting cable) that lead to the strain gauge system.

– Remove the entire front panel.

– The main PCB is connected to the front panel by 5 screws (one in each corner and one to ground the keypad overlay). Remove these 5 screws.

– Remove the cable that leads to the keypad.

– You can now remove the main PCB.

Make sure you duplicate the solder bridges from the old main PCB to the new one!

Install the new main PCB (follow the above steps in reverse order).

Switch the scale to BPI mode.

You will now need to program the scale with the appropriate data set.

Check the following points and adjust them if necessary:

Zero point offset value

Linearity

Span (Sensitivity)

SARTORIUS QC - Scales

Note:

Installation of the YDI01IS-0CE (Industry Printer)

It is possible to use the industrial printer (paper strip or label) YDP01IS-0CE

(from the isi range) together with the QC scales.

The following changes must be done on the QC´s menu configuration:

9600 Bd

Space Parity

2 Stopbits

Handshake 2 Z.

Print Art-Nr ID

5 1 7

5 2 2

5 3 2

5 4 2

7 4 3

(Restriction: Date/time print is not possible; for this feature you need to use the YDP02-0CEV3)

The following initialisation procedure must be done on printer YDP01IS-0CE if paper shifts out several print lines after pressing FEED key:

Hold FEED key while power switching on. Release if paper begins to shift out automatically.

Wait until shift out stops (approx.after 20cm). Then again press the FEED key.

Switch power off and on again, now FEED works for the rest of printers life with only one line shift.

You can use the printer YDP01IS-0CE for label printing!

Frequently Answers and Questions

How do I access the scale operating menu?
Press 'e' to switch the scale off and then on again. While all segments are displayed, briefly press the '=' key. A '1' will be displayed. You can then navigate the menu using the 'u' and 'p' keys.
How do I activate the BPI mode?
Disconnect the AC adapter from the scale and open the display unit by removing the 4 screws at the back. Carefully pull the front panel far enough away from the rear panel to access the BPI switch. Reconnect the AC adapter and switch on the scale by pressing 'e'. Once 0.0g is displayed, move the BPI switch to the right. Wait until the segment check has lit up at least 3 times; the scale is now in the BPI mode. Move the switch back to the original position; the scale now shows the normal weighing display. Close the display unit.
What are the different types of error codes that may be displayed?
The manual lists several error codes, including Err01, Err02, Err03, Err10, Err11, Err12, Err20, Err22, Err23, Err30, Err50, Err53, Err54, Err55, Err62, Err63, Err64, Err70, Err101, Err102, Err103, Err104, Err110, Err220, Err230, Err237, Err241, Err243, Err247.
