Power, control; iSaCS

For technicians and partly for sales managers!

 

 

 

 

The scanner 3DHISTECH iSaCS has modified power supply and electronics compare to the Pannoramic 250. These modifications are required because the scanner is based on a modular MIDI and contains a staining and cover slipping unit that have new components.

 

·                             The entire power unit has also got a separate housing and is arranged in a tower; the so-called “Power tower”.

·                             The internal construction and used components are derived from the scanner Pannoramic 250 Flash and the Pannoramic Confocal.

·                             Control of the staining and cover slipping units are realized by the main control electronics and the local electronic units.

·                             Power for the main electronics and connected components is supplied from the Power tower.

·                             The power supply of the Lumencor SPECTRA light engine is realized with an external power supply.

·                             Software-related settings and checks are based on the software version 1.20.

Housing and construction

 

 

The main components of the power supply and control electronics for the scanner are arranged in a “Power tower”.

In the bottom part a fan with particle filter is implemented, so the power supply and other electronic components reach cooling.

A temperature sensor is implemented to avoid probable overheating.

 

·                             The entire power tower is mounted by 4 bolts to the truss of the iSaCS.

 

 

 

More detailed information about the internal construction can be found in the “Power tower gallery”.

                                            Power input and main switch

 

The power input connector and mains switch consist of:

·                   Power cord connector (Mains input)

·                   Mains switch

·                   Fuse housing with fuses

 

The double-pole mains switch disconnects the mains power from the internal power supply.

Each pole is secured by a slow-blow fuse of T3.15 A / 250V.

 

 

 

 

 

 

 

 

 

 

 

 

230V~ or 100V~

 

The alteration of the mains power input in the range from 100V~ to 240V~ is reduced to the use of the appropriate mains power cable (additionally, various connector outlet constructions are used in different countries worldwide).

If the mains power is changed from 230V~ to 100V~ or vice versa, no alterations are required inside the scanner. The change of the mains power is fully handled by the input voltage range of the power supply; see also “Power supply TDK -Lambda.

 

 

 

More information can be found in the “Power input gallery” and the “Power input slide show”.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Check or replace fuses

 

Disconnect the power cable.

·                   Open the fuse housing and remove the fuse container.

·                   Push the fuse container lock guide (1) to the center of the fuse container (for example with a flat screw driver).

·                   Pull the container out (2) of the housing.

·                   If the fuses are dismounted, use an Ohmmeter to check the fuses.

·                   If a fuse exchange is necessary, always use a slow-blow fuse of T3.15 A / 250V (100V~ or 230V~ power input is unimportant).

Power_Supply_type

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The internal OEM power supply TDK-Lambda with an input voltage range of 90V~ to 264V~ AC, an input frequency of 47Hz ~ 63Hz and output voltages of 5V-, 12V- and 24V- DC supplies the internal units of the iSaCS with power. Inside the controller units (USB, X-, Y-, Z-motor controller, power distribution board and some stepper motors) a local power supply is located and this create further, required voltages.

 

·      The power supply is short circuit-protected.

·                  The “Housing Switch” is used to switch off the entire scanner if mechanical malfunction or other emergency situation occurs.

·                  If the input voltage is changed from 230V~ to 100V~ or vice versa, no alteration is required inside the scanner.

 

Remark

The fan of the power supply is removed in the iSaCS; the cooling of the components is done by the central fan of the power tower.

 

 

 

 

 

 

 

 

 

 

 

Power input

 

·                Press the power input cover a bit downward until the clamps (1) are disconnected from the upper housing part and remove the cover.

·                Connect the power wires as shown (2).

·                Fit the parts (a) into the slots of the base cover and the clamps (b) into the appropriate slots of the top cover.

Housing Switch and standby

 

The Housing Switch inhibits and stops the switching power supply by the help of a relay, but the mains voltage of 100V~ or 230V~ is not interrupted; the power supply goes to standby.

 

By shorting the pins “2” and “3”, (the voltage between the two pins is about 15V) the power supply control is inhibited and all output voltages are disabled (standby mode).

If there is no connection between the two pins (or the standby option is not used), the power supply is running continuously.

·                   These two pins will be shorted via a relay, if the “Housing Switch” is active and closed.

Housing Switch

 

The Housing Switch is situated in the left handed side wall of the scanner and is used to inhibit the power supply. The power distribution is interrupted and all movements are stopped immediately.

 

·                          If the power is supplied again to the scanner, the software has to be started again.

The power outputs can be switched by software; so momentarily unused units can be switched off, or if any emergency event occurred, all outputs may be disabled.

The outputs are switched by the use of relays.

The communication between software and the power distribution board is realized with the control bus connector; this is connected to the USB controller and is used to switch on / off the power outputs and to transfer status information to the USB-controller.

The temperature sensor input controls the fan output directly, without any scan software control, bat the temperature value and the fan speed can be read from the software; see also the service program, Low level service, power supply. The fan speed is controlled via the PIC on this switch board, depending on the sensed temperature value.

 

 

 

 

Enable or disable of the switch board

For technical enhancements and upgrades, the type of the entire “Power distribution & switch board” can be defined or the board might be disabled.

The relevant parameter and value is found in the section [Microscope] of the file “MicroscopeConfiguration.ini”.

 

To enable the switch board:

PowerSwitchBoardType=PowerSwitchBoard_Type1

Actually, the most recent “Type1” is used.

 

To disable the switch board:

PowerSwitchBoardType=PowerSwitchBoard_None

 

Remark

Usually, the board is enabled.

If the entire “Power distribution and switch board” is disabled, the power supply for the camera and all other connected units is disabled; the scanner will not start correctly or the powering of the appropriate units have to be realized otherwise; e.g. with external power supplies.

The board is found in the “Power tower” see also: Distribution and switch board

 

 

 

Connectors Fan1 and Fan2

Via the connector “Fan 1” the fan in the bottom part of the power tower is connected via the line VERL-1; the connector “Fan 2” is not used.

 

 

Temperature sensor input

The temperature sensor input is an I2C bus input and the temperature sensor is connected via the line “TSRL-1”.

 

 

 

 

 

 

                                            Temperature

 

The temperature inside the Power tower is sensed via a temperature sensor by the help of the PIC on the switch board.

 

Probably errors may be:

·                   Temperature sensor is not connected; any wire is broken or has no contact.

·                   Sensor is defective.

·                   Power distribution and switch board is defective.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Temperature sensor; TSRL-1

 

The temperature inside the Power tower is sensed via a temperature sensor by the help of the PIC on the switch board.

 

Probably errors may be:

  • The temperature sensor is not connected; any wire is broken or has no contact.
  • Sensor is defective.
  • Power distribution and switch board is defective.
  • Wrongly defined  address of the sensors (after exchange).

 

 

Sensor type:    Maxim DS1621S

 

                               Voltage:           3.6V ~ 5.5V max

                               Data sheet:      DS1621S

 

 

 

 

 

 

 

 

 

 

 

Temperature sensor, fan and fan control

 

Because the fan of the power supply is removed and cameras needs cooling (their temperature must not exceed 60º C (140º F)), temperature sensing and active cooling of the scanner is required.

The sensed temperature value is used to control the speed of the fans directly; without any interaction of the scan software “SlideScanner.exe”.

In the service program, the sensed temperature is shown in [ºC], the fan speed is shown in a value between 1 and 255; 255 is the full speed of the fan.

 

·                   The sensed temperature value and the fan speed can be read with the service program any time.

 

If the field “Error” is different from zero, a HW error exists in the temperature sensor and fan control electronics; depending on the error code.

 

 

 

Error codes

16                              Fan error; the spinning speed of the fan is too slow; the fan blades moving too strong; they have too much resistance in the bearing.

32                              Fan error; the blades of the fan are not spinning; check cabling, connection; try to rotate the fan blades manually; check for any mechanical reason also.

64                              The temperature of 60º C (140º F) reached; check and clean the dust filter of the fan; check the fan’s connection and the movement of the blades also.

128                            Power tower overheated; the relays are switching off; the power to the connected units is interrupted; the temperature reached 70º C.

·                                         Because the error bits are arranged in a byte, other values are possible if more errors existing at the same time; e.g. 96= 64 + 32.

·                                         If the units are switched off by overheating, the scan software SlideScanner.exe shows the error message

 

 

Error occurred

and stops working.

 

 

 

 

 

 

 

 

                                 Power Fan

 

The spinning of the blades is recognized by the PIC.

 

Probably fan errors may be:

·                                 The signal of the fan spinning sensor (situated inside the fan) is not recognized by the fan control logic, because the fan is not or not well connected; the fan blades does not rotate (any mechanical or cabling reason) or the fan is defective.

·                                 If the fan speed is too slow please check and clean the dust and particle filters or the fan blades moving too strong; they have too much resistance in the bearing (fan goes defective).

·                                 The power distribution and switch board is defective.

The USB controller connects, supplies and controls all the addressable units and outputs; these are:

 

·                   X-Y-Z-motor control

·                   Power distribution & switch board

·                   Tray loader

·                   Slide Loader

·                   Objective changer unit (OC)

·                   Preview BF illumination

·                   Barcode illumination

·                   Tray sensor

·                   Slide sensor

 

·                   The USB controller gets its +-24V power directly from the tdk lambda OEM power supply.

 

 

Control

 

The USB controller receives the command for the units from the program SlideScanner.exe (the scan program) or the SlideScannerService.exe (the service program) via the USB control port of the PC and the USB cable.

All units contain separate electronics and are connected via a bus system. To differentiate the units, connected to the USB controller, all stepper motor electronics and the unit-controller as well has an address. Each data transfer starts with the specified address for the unit and is listen by all units at the same time, but only this unit receives the message, which internal address and the message address is identical. The stepper motor electronics can receive commands (number of steps to go and direction) and can send status information (desired position reached and the status of the sensors Home1 and Home2).  The status information is sent via the USB cable to the software, hereby the address of the unit is used also.

With this solution it is possible to change the “Hirschmann” connection with another “Hirschmann” cable (Connectors A ...F; e.g. for fault detection) without any risk or functional restrictions. The label of the cable for digital electronics has no reason in functionality; it differentiates the cables from each other instead, because some cables are shorter than others.

 

Important

 

The construction of the controller powering on the board does allow the drive of maximal 3 stepper motors at the same time!

 

·                             Please take this into account, if you are working with the service program and the batch test program module!

Bus extender

 

The addressable units are also connected via the “Bus extender” because the number of connected units increased. The bus contains the power supply for the unit (24V-) and the serial bus (I2 C). Via the serial bus the connected units are addressed, receive command and control information and returns status information.

Each connected unit contains a local power supply to create further, required voltages.

Cabling of addressable units

The addressable units are connected with the “Binder” connector (except the Power distribution and switch board); the connection is secured with a knurled nut. On the other end of the cable a “wire to board” connector is used.

 

Important

Please do not use pliers to loosen or tighten the cable header lock nut. If there is too much force used on the connectors, the soldering of the connector may be destroyed and broken and the appropriate motor or unit will not work.

The addresses are used by the scan program and the service program to select the unit; these addresses are programmed into the specified unit and can be changed via special software only. It is important, that none of these addresses should exist twice inside of one Pannoramic scanner, otherwise command and status mismatch occurs.

If data transfer is in progress, all addressable units listen to the address of the data stream.

If the address of the unit is identical with the address of the data stream, the addressed unit is found and this receives the information.

 

 

 

 

 

 

Connections

·                             The length of the cables is so dimensioned, that every bus connector may be reached with any bus cable header.

 

·                             Positions of the bus cables may be changed without any risk or functional restrictions; e.g. for fault detection!

 

 

 

 

 

 

 

 

 

 

 

 

 

 

X-Y-Z-ND-motor and Flash light control

 

 

 

 

Because in the P250 the ND-motor is additionally implemented, the Flash light control has to be resolved and the focus motor is of a different type, a new electronics box was implemented.

The unit realizes the control, connections and interfacing of the following units:

 

·                   X-motor

·                   Y-motor

·                   Z-motor (focus)

·                   ND-motor

·                   Flash light control for brightfield scan

·                   Trigger connection of the CIS-camera

·                   Darkfield illumination

 

·                   The power supply and the control of the addressable unit are realized with the “Hirschmann” connector (Bus connector).

 

·                   The X-, Y-, Z- and ND-stepper motor control electronics is realized with the appropriate module; these motors itself does not contain control electronics.

 

·                   The motor modules are all from the same type and are interchangeable without address modifying.

 

 

Flash light control

 

The arc frequency of the Flash light source is controlled via the software.

The connector “CIS-camera trg” is software controlled and defines the shutter time and pulse width for the CIS-camera.

 

 

 

Darkfield illumination connector

 

·                   The two connectors “DF illumination” provide the power for the darkfield illumination and are interchangeable; the intensity can not be affected.

 

 

 

 

 

Motor cable headers

 

The wires of the appropriate stepper motor as well as the wires of the sensors are directly connected to the electronics via the motor cable headers.

The construction of the connectors does not allow an interchanging of the two cables to each other, but the motor can be connected to another module; e.g. for fault detection.

 

·                   The sensors Home1 and Home2 are also connected via the motor headers.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Important

Please do not use pliers to loosen or tighten the cable header lock nuts. If there is too much force used on the connectors, the soldering of the connector may be destroyed or broken and the appropriate motor will not work or may working very noisy.

 

Hint

 

·                             For test purposes and fault detection, the motor cable header pair may be connected to another motor output; e.g. the X-motor headers are connected to the Y-motor output.

·                             In this example, the service program Y-direction will be used to move the X-stage!!

·                             Before SlideScanner.exe will be started, the motor cable headers have to be connected to their original, correct motor connection!

Because the entire staining and cover slipping part of the iSaCS is controlled via an USB cable to the PC, different from the scanner part, and the staining and cover slipping part is divided into several control electronics, addresses are used to distinguish the data stream for the controllers.

 

·                             The addresses are programmed into the unit, so each unit is unique in the system, nevertheless several controllers are from the same construction!
