Warnings - Operating the instrument

The Leica ST5020 may only be operated by trained laboratory personnel, according to its designated use and per the present Instructions for Use. In case of emergency switch off mains and unplug the power chord. While working with reagents (filling / emptying the reagent stations, working on the instrument while the lid/s is/are open) appropriate protective gear (lab coat, gloves, safety goggles) must be worn. Make sure to operate the instrument either with the activated carbon filter or with the exhaust air hose. Even when the instrument is operated according to its designated use, hazardous solvent fumes develop, which are damaging to the operator’s health and do also pose a risk of fire! Risk of fire, when working with an open flame (Bunsen burner) immediately next to the instrument (solvent fumes)! - Therefore, keep a safety distance of 2 meters! If a staining program is to be interrupted for an extended period of time, do not leave any slide racks in the tap water stations, in order to prevent them from drying out.

Warnings - Cleaning and maintenance

Prior to each maintenance and/or cleaning, switch the instrument off and disconnect mains power. Do not clean the instrument with solvents containing acetone or xylene. No liquid may be spilled into the internal components of the instrument - neither during operation nor during cleaning.

When working with cleaning detergents, comply with all safety instructions by the manufacturer of the product and the laboratory management policy. Wash the tap water and reagent stations in the dishwasher at a temperature of max. +65°C (149 °F). Use a standard detergent for laboratory dishwashers. At any rate avoid washing the stations at higher temperatures, as the stations may become deformed!

Spilled solvents (reagents) have to be wiped away immediately! - In case of long-term exposure, the lid surfaces are only conditionally resistant to solvents! To clean the lids, control panel and housing, use mild household detergents; - see safety instruction above for non-appropriate ingredients!

Caution with sequences which involve an oven at the initial step. In this case the loading unit, out of which the specimen holder is removed via the transport arm, must NOT be filled with an inflammable reagent (e.g. xylene). As the oven temperature is up to 80°C (176 °F), the reagent may ignite and cause damage to the device and to the samples.

For the same reason, steps conducted INSIDE an oven must never be carried out from a reagent station with inflammable reagents.

3.5 Container system

Reagent container

The Reagent containers can be individually removed for filling. For use, fill the reagent containers to the line marked on the inside

(approx. 450 ml capacity) and place into position in the instrument consis-

tent with the programs you wish to run. Ensure that the reagent containers are correctly seated and that the

handles (1) are over to the side and will not obstruct slide rack movement. Lids (6) are provided to reduce evaporation while the reagent containers are not in use.

The Load and Exit drawer containers (E25 and L36) can be filled with a reagent if desired. However, the instrument will not control the immersion time in these stations.

Wash stations

The wash system consists of five (optional six) wash stations each capable of holding one slide rack. Water enters the wash station through a connection piece (2) in the base and exits from the overflow lip (3) at the top left hand edge.

Wash stations have a locating pin (4) and can only be inserted one way. Take care when fitting or removing wash stations as excessive force may damage the O-ring (5) used as a seal. Lubricate the O-ring seal before fitting a wash station.

To use the wash system, slowly turn the laboratory tap on fully. The flow control valve in the Leica ST5020 will limit the total water flow in the wash stations to 1.6 liters/minute/station.

If the water flow drops below this level for any reason the

Fig. 4

wash period specified in the program may have to be extended.

instrument feet

Bring the instrument to an exact horizontal position by screwing the adjustable feet in / out as needed.

Adjustable

To do so, proceed as follows:

• Remove all vessels located in stations 1 - 24 so that the vessel holder frames can be used to support the box level for measuring purposes.

• All four instrument feet (37) are height-adjustable. To adjust, place single head wrench, size 13 (standard delivery) onto hexagon bolt (36) and adjust each foot as needed.

Fig. 21

Abb. 22 shows all four points (A to D) where the box

level must be positioned for leveling the instrument. For leveling, the box level must be placed onto vessel holder frame (39). - Do not place the box level elsewhere.

Make sure, all four instrument feet are firmly set on the bench surface once the instrument adjustment has been completed.

• For leveling, position box

level (38) alternately in positions (A and B) - see Fig. 22 on the vessel holder frame.

• Screw the instrument feet inward / outward as needed,

gradually bringing the instrument into a horizontal position. Start with the instrument foot located opposite the highest point of the laboratory bench.

4.9 Alarm functions

Instrument alarm

The instrument alarm is generated from within the Leica ST5020. The instrument alarm is used for all alarm situations.

Remote alarm

This alarm is external to the Leica ST 5020. Any alarm generated in the instrument, no matter of which alarm type, is passed on to the remote alarm system, even when the type 1 instrument alarm is switched off. The remote alarm sound/volume is the same for all alarm types - individual sound and volume settings selected in the ALARM menu (see

chapter 5.4.2) are disregarded.

4.10 Transport

The following measures must be taken if the instrument is to be transported:

• Remove all the racks.

• Empty all reagent containers.

• Secure the transport arm of the instrument.

• Disconnect the instrument from the supply voltage.

• Detach the water inlet hose and the water drain hose.

• If necessary, detach the air evacuation hose.

• Reattach the carrying handles (see

4.2).

• If the instrument is transported over longer distances, pack the instrument in its original shipping box and follow the measures for securing it for transport.

Chapter

Connecting a remote alarm device

The remote alarm system which can be optionally connected works with a potential-free relay. If an alarm is generated, the alarm circuit closes. The remote alarm device connected to the instrument must be rated at less than 2 amp. A maximum voltage of 24 V AC/DC may be present. The remote alarm device is connected to the printer via a 6.3 mm-diameter jack connector (optional accessory). For details on how to connect a remote alarm device to the Leica IP, please contact your local Leica sales office or the manufacturer Leica Microsystems Nussloch GmbH directly.

Securing the transport arm:

• Change to the Supervisor mode.

• Call up the keyboard (e.g. as required for entering the password, see

• Enter the command “#transport“.

The arm moves down into station 6 where it remains and can no longer be moved. After switching the instrument off, it is ready for transport.

↓

If the Reagent Management System (RMS) is switched on, the table headers are displayed as buttons.

The following limit parameters can be defined for the RMS:

• Maximum number of days the reagent may be used.

• Maximum number of racks that can be processed until the next reagent change.

In ‘instrument status’ a red bar in the station button indicates how long a reagent has already been used depending on the values entered here.

The longer the red bar, the closer the time when the reagent will have to be changed. (See chapter 5.5.1)

Press the header buttons to access the corresponding numerical keypads for entering RMS data.

Fig. 44

Numbers between 1 and 99 can be entered in both columns.

• Highlight the reagent you want to delete from the list.

• Press DELETE and confirm the screen prompt. The reagent is removed from the list and the blue highlighting bar moves one row down.

ata backup

This menu allows all instrument data to be written to a PCMCIA card. It is even possible to load saved data from such a card into the multistainer memory. The data can only be backed up in supervisor mode (9, fig. 48). If a staining program is running, it is therefore impossible to write data to a PCMCIA card or load data from the card into the memory.

To ensure compatibility of card and instrument, the card must be formatted IN THE INSTRUMENT before its initial use. Using a PCMCIA card that was formatted on a PC (e.g. with Windows XP) can lead to loss of data.

→

Formatting a PCMCIA card:

• Change to the Supervisor mode.

• Call up the keyboard (e.g. as required for entering the password, see

Chapter 5.4.3)

• Enter the command “#format a:“.

The card is formatted. At the end of the process, the information line indicates whether the

Fig. 48

formatting was successful or not.

The following data is saved or loaded:

• All settings in the USER INTERFACE and MOVE menus as well as the print settings from the DISPLAY/PRINT menu.

• The current station settings.

• The reagent list.

• The program list with all program details.

• All saved clips (code and color allocation).

• The error log (Errorlog.txt).

Leica ST5020

Fig. 49

Only the error log can be read directly from the card. All other data is stored in code form and cannot be edited with normal PC tools (e.g. text editing).

5. Operation

Important! At least 1 MB of free memory is required on the PCMCIA card. Otherwise, data backup cannot be completed and the writing of the data to the card will appear to take a very long time. In this case (if data backup lasts longer than 2 min.), remove the card from the slot, replace it with an empty card and repeat data backup.

Backup the data as follows:

• Insert a PCMCIA card into the card slot beside the mains switch (see

Caution! When you press a button in the data backup window, all data saved on the PCMCIA card or elsewhere in the instrument is automatically overwritten. The data is always saved or loaded into the instrument in its entirety. It is not possible to transfer individual files on their own (e.g. just the reagent list but nothing else).

• If you do not want to back up any data after calling up the menu, e.g. if you called up the menu by mistake or there is no (empty) PCMCIA card available, do NOT insert the card into the slot and press the BACKUP button to leave the data backup screen. No data will be written and the text "Backup inprogress..." does not appear. However, if you press RESTORE, the instrument will restart as described above.

5.5.1 Station buttons

Each of the 40 stations is configured as a button that can be pressed to directly access the STATION DETAILS menu. The station buttons are divided into three lines containing different types of information, depending on each individual configuration.

5.5.2 Station types

• The first line contains the station number (2) plus a letter (3)

indicating the station type. These are: R: Reagent station L: Load station

O: Oven station E: Unload station W: Water station

Empty stations do not carry any letters.

• At the left border of the button a bar (4) may be displayed, providing different types of information, depending on the type of station.

• The second and third line are activated when a station is used in a program run.

• The first line of a station turns white (5) when the transfer

arm is located above that station.

• In the second line the program code (6) is displayed in

the clip color that has been allocated.

• The third line contains a rhombus (#) followed by the se-

quential number (7) of the rack. This rhombus counts the number of racks which pass the station everyday. When

Fig. 51

no. 99 is reached and everyday at 24:00, the rack counter is reset to “0“.

Load station

• There is a maximum of four load stations (L33-L36), L36 being nonchangeable. Load stations do not have a bar on the left border.

• After a new rack has been placed into a load station, the second line of the corresponding button indicates which program (color and code) has been recognized and will be carried out. The rhombus (#) indicates that the rack has been detected by the software and will be processed as soon as possible.

Page 64

5. Operation

Defining exact steps

↓

As there is potential for timing clashes to occur when multiple racks are present in the instrument, steps which require precise timing are designated as ‘exact’ in the program.

• Press EXACT to alter between yes (=exact) and no (not exact).

• Immersion times at exact steps are achieved to within ± 1 second. Immersion time at non-exact steps is at least as long as defined, most of the time however, non-exact steps take longer than defined, as racks due for non-exact steps receive attention only as the transfer arm becomes available after an exact step.

• Define ‘exact’ steps only when really needed. The more exact steps, the slower and less flexible the instrument (instrument throughput decreases).

If you interrupt the staining with PAUSE, take care not to do so while an exact step is in progress. Otherwise, the program will be stopped and the duration of the step will be extended by the duration of the pause. This can the cause errors during staining. If PAUSE buttun has been pressd druring an exact step is in process, a warnig message will be appear in the dialog box

Setting the dips

• Press DIP to switch from yes (= Dips activated) to no and vice versa.

• Duration and speed of one complete up and down movement (dip) are selected in the MOVEMENT menu. The parameters selected there will be applied to all programs. Increasing numbers of dips reduce instrument throughput.

For exact steps the following applies: If the immersion time of an exact step is shorter than the time to do the set number of dips, only the number of dips that fit into the immersion time will be done.

• Keep creating program steps until your program is complete.

• Program steps whose definition is not correct (duplicate station

assignment, incorrect reagent,...) are highlighted in red in the REAGENT column. Such steps must be corrected accordingly.

• A program will not be ready to start until all details have been defined.

Three different types of “last steps“ can be defined:

1. Last step = unload station.

Go to CHOOSE STATION and select EXIT as last station.

2. Last step = transfer station to Cover Slipper (optional).

go to CHOOSE STATION and select CV as last station. The REAGENT column from the reagent list now allows selecting

between CV program 1 to CV program 4. The transferred rack is automatically processed with the selected program (1 ... 4) in the CV5030.

Leica ST5020

3. Last step = any station other than EXIT or CV.

Programs do not necessarily have to finish in the unload station, as a particular staining protocol might e.g. have to end with a specific reagent not contained in the last station.

Be sure to define the DURATION of the last step. Otherwise it will not be carried out (default duration 00:00 will be assigned). Otherwise, the program cannot be started.

• If in user mode, a message is displayed telling the user that supervisor mode is required and asking whether to switch to that mode (see

chapter 5.8.2).

If an unknown clip is detected, proceed as follows:

1. Select the station carrying the unknown clip - the station is displayed as having been pressed (wider border) - as e.g. station L34 in (Fig. 60).

2. Press the color button corresponding to the actual color of the clip on the rack. The color selected will be displayed on the station button (here: L34).

3. Press CONFIRM to go back to INSTRUMENT STATUS. The color will be allocated to the station (clip) as selected. If the selected color was already allocated to a different program, the 3-digit program code of that program will be shown as well (see also Creating programs

5.8 Staining

Prior to starting a staining program, thefollowing preparatory steps must be taken:

• Optimize all USER INTERFACE parameters.

• Programs needed for staining must be ‘ready-to-start’.

• Stations have to be configured and filled according to configuration.

• Racks needed for staining must be equipped with a clip and filled with the slides to be processed. Place the clips (1) onto the rack with the transponder (2) facing outwards.

• Make sure the instrument “knows“ all clips needed for staining.

For the same reason, steps conducted INSIDE an oven must never be carried out from a reagent station with inflammable reagents.

5.8.1 Loading the racks

• Racks may only be loaded via the load stations (front right of the instrument).

• Open the load drawer and insert the racks as shown in stations with the clips facing outwards (towards the user).

• Each rack must bear a clip corresponding to the program to be run.

• Close the drawer completely.

• Once identified, the clip colors / program codes are displayed in IN- STRUMENT STATUS (3) (see also

chapter 5.5).

Automatic program start

• Once all components have been identified and are ready to be started, the staining programs will start automatically. For programs to be started

(automatically), the instrument must be at

user access level (4).

If there are already some staining programs running, the new racks are integrated into the overall process as soon as the software detects capacity for a new program start. Racks are processed in the order of optimized throughput, not

necessarily in the order in which they have been placed into the load station.

Loading a clip not allocated to a program (any longer)

• If a rack placed into the load station carries a clip which is not allocated to any program or the color of which is allocated to a program not ready to be started, in the second line of the corresponding load station three question marks “???“ will be displayed instead of a program code.

• Processing options with such a clip depend on the current instrument mode.

- In supervisor mode, the color of a ‘ready-to-start’ program can be

assigned to the clip (see

chapter 5.6.3).

- In user mode, an error message will be displayed, specifying why

that particular rack cannot be processed. At the same time, the corresponding alarm sound is triggered. Remove the rack to acknowledge the error message and stop the alarm; close the drawer.

Caution - bear in mind any steps defined as exact! During the color allocation procedure the instrument is paused. The programs in progress are paused until the color allocation has been completed and the instrument is switched back to user mode.

Manual program start

5. Operation

• If a rack carrying an unknown clip is placed into the load drawer, the CLIP COLOR menu opens up automatically. If any staining processes are already in progress, a screen prompt will open up inquiring whether the user wishes to access supervisor mode.

- CONTINUE stops the selection procedure and continues the stain-

ing processes in progress. The load station button will display three question marks instead of a program code “???“ and no color allocation will be visible. - The rack must be removed.

- ADMINISTRATOR opens up the keyboard for entering the password

and then switches over to CLIP COLOR for a color to be allocated.

5.8.4 Finishing programs

Unloading racks from the unload drawer

If a rack is located in the unload drawer, the alarm type 1 sounds.

• The code of the completed program and (in the bottom row) the basket number are displayed in the unload station symbol. The colored program indication blinks in two-second intervals.

↓

• Carefully open the unload drawer and remove the rack. You may also remove the entire reagent container together with the rack and replace it by another container.

5. Operation

• Close the unload drawer - program code and rack number must disappear from the station button.

• If, despite the unload drawer having been opened and closed several times, the instrument still displays code and rack number of the rack already removed, the transponder or the automatic recognition system might be defective. Press CANCEL RACK to manually ‘unload’ the clip.

Fig. 70

Removing racks from stations other than unload

If a program finishes in a station other than unload, alarm type 3 sounds at the end of the program and there will be a screen prompt requiring the user to remove the rack.

• Press CONTINUE to confirm that the rack has been removed from the station. This is necessary, as the instrument will otherwise not be able to recognize whether there is still a rack in that station or not.

• Confirmation of rack removal also switches off the alarm. The staining program is considered to be finished and removed from the list of pending staining runs.

7. Troubleshooting

7.1 General

7.2 Correcting errors

The Leica ST5020 is equipped with a troubleshooting system. If an error is detected, detailed error messages and corresponding user

instructions on what to do are displayed on the touch screen. For all correctable error conditions the instrument will take corrective ac-

tions to protect the specimens. Details of all staining protocols carried out are recorded in the daily run

log. The daily run log can be viewed and/or printed in the VIEW/PRINT menu.

If any programs are in progress, check the job queue containing the staining programs to be run.

If all programs are completed, check the error log for error messages: access the error log (either view in menu VIEW/PRINT --> ERROR LOG) or

print it out - entries are listed in chronological order.

7.3 Power failure

• Check whether there is a general power failure (no mains power).

• Check whether the mains plug is inserted correctly into the wall outlet and whether the wall outlet is switched on, if applicable.

• Check whether jumper cable (or UPS cable) is inserted correctly into the corresponding sockets.

• Check whether the mains switch is switched on correctly.

• Check whether one of the four secondary fuses is defective. Some instrument malfunctions / failures are caused by defective fuses.

7. Troubleshooting

7.4 Replacing the secondary fuses

Prior to exchanging a fuse, always switch the instrument off and unplug the mains cord. Defective fuses may be replaced only with the replacement fuses supplied together with the instrument.

Important! Follow the instructions below to make sure you select the correct replacement fuse for each fuse holder.

Selecting the correct replacement fuse

The amp value (here: 2A) printed on the fuse and the amp value next to the fuse holder on the rear panel of the instrument MUST be identical!

Four fuse holders, marked F1 through F4, are located at the rear panel of the instrument, below the power supply sockets.

Check the malfunction table on

page 78 to find out, which

fuse needs to be replaced.

Example:

Touch screen failure:

--> Exchange fuse F1.

The fuse value is shown on the metal caps of the replacement fuses - the imprint looking more or less as indicated above (may vary slightly depending on the fuse type).

Amperage (A) is the parameter that is important for allocating fuses correctly to the corresponding fuse holder (in the example above: F1/T2A )

Fig. 72

To replace the fuse in fuse holder F1, select the replacement fuse marked ‘2A‘ (see

Fig. 69).

Only the fuse marked ’2A‘ can be inserted into fuse holder F1. The same applies for the remaining fuse holders F2 - F4, i.e. always make sure the amp rating on the fuse corresponds to the amp rating indicated above the fuse holder.

Instructions for Use, V1.9, RevD - 12/2012
