Power, control; PCON

For technicians and partly for sales managers!

 

 

 

 

 

 

The scanner Pannoramic Confocal got some modifications concerning the power supply and the electronics also, these modifications are required because in practice a scanner unit, based on the modular MIDI and a spinning disk imaging system are combined, so new components are also implemented.

 

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

ˇ      The internal construction and used components are derived from the scanner P250.

ˇ      Software related settings and checks are based on the software version 1.19

 

 

 

 

Overview

The power supply and control electronics consists of the following components and units:

 

 

See:    “Power tower slide show”

 

 

 

 

 

 

 

 

Important remark

           

ˇ      After maintenance or service and performed tests of the scanner are 100 % finished, protective ground connections and other safety regulations related to hazardous voltages, accessible conductive parts and dangerous to life parts have to be checked (again).

Housing and construction

 

 

 

 

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

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

A temperature sensor is implemented to avoid probable overheating.

 

ˇ      The entire power tower is mounted by 4 bolts to the truss of the PCON.

 

 

 

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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Units

 

 

 

 

 

Power supply TDK -Lambda

Power distribution and switch board

USB controller unit

X-Y-Z-motor control

Stepper motor

Mechanical shutter

Immersion liquid feeder

 

 

                                            Power input and main switch

 

The power input connector and mains switch consists 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.

ˇ      Push the fuse container lock guide (1) to the center of the fuse container (e.g. with a flat screw driver) and pull it out (2) of its housing.

  • If the fuses are dismounted, please use an Ohmmeter to check the fuses.
  • If a fuse exchange is necessary, please use always a slow-blow fuse of T3.15 A / 250V (100V~ or 230V~ power input is unimportant).

 

 

 

 

 

 

 

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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Power supply TDK -Lambda

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

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 PCON 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 these create further, required voltages.

 

ˇ    The power supply is short circuit protected.

ˇ    The “Housing Switch” switch is used to switch off the entire scanner if mechanical jamming or any other emergency situation occurs!

ˇ    If the input voltage is changed from 230V~ to 100V~ or vice versa, no alterations are required inside the scanner!

 

Remark

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

 

 

 

 

 

 

 

 

 

 

 

Power input

 

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

ˇ      Connect the power wires as shown (2).

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

Output voltages; power

  • 5V- /10A DC
  • 12V- / 13A DC
  • 24V- / 18.75A DC

 

The outputs are short circuit protected and are ground independent (the minus pole is not connected to GND) so each voltage has a plus (+) and a minus (-) pole.

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 110V~ or 230V~ is not interrupted; the power supply goes to standby!

 

By shorting the 2 pins “ and “, (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 / 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.

Power distribution and switch board

 

Outputs, Connections

Current amplifier

Temperature

Temp. sensor; Fan control

Power Fan

Aventos servo drive unit

 

 

 

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.

 

 

 

 

 

 

 

 

 

 

Outputs, Connections

 

1= reserve 5V- output

2= reserve 5V- output

3= Power output 12V-        for the logo LEDs in the front of the housing

4= Power output 12V-        for the PCO.edge scan camera

5= Power output 24V-        switches the current amplifier for LumencorŽ SPECTRA.

6= Power output 24V-        switches the Aventos servo drive to drive the motorized front door

7= reserve switch1

8= reserve switch2

9= reserve 24V- output

 

5V= Power input from the TDK-Lambda power supply

12V= Power input from the TDK-Lambda power supply

24V= Power input from the TDK-Lambda power supply

 

The switched outputs are ground independent (the minus pole is not connected to GND) so each voltage has a plus (+) and a minus (-) pole.

 

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

 

 

 

Connectors Fan1 and Fan2

Via the connector “Fan the fan in the bottom part of the power tower is connected; the connector “Fan is not used.

 

 

Temperature sensor input

The temperature sensor input is an I2C bus input and the temperature sensor is connected here.

 

 

 

 

 

 

 

Current amplifier for Lumencor SPECTRA light engineŽ

 

The current (power) amplifier is realized by the use of a relay; it is switched on or off by the output 5 of the “Power distribution and switch board”.

 

Because the relay on the “Power distribution and switch board” output 5 can not handle the required current of 5A DC a second relay is used.

 

The relay is found in the “Power tower” see also: Power amplifier

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

                                            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.

 

See also:       “Temperature sensor”

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 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.

ˇ       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.

ˇ       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.

                                            Aventos servo drive unit

 

The Aventos servo drive unit is used on the left side of the front door mechanics to open and close the front door. The unit gets its power of 24V- / 1.4A from the output 6 of the “Power distribution and switch board”.

By disabling the power output via software, the opening of the front door can be prohibited. The front door may be opened by the user only in specified states of the scanner software; e.g. for filling the immersion liquid feeder.

SWITCH, SYNC and COLL

 

The button “SWITCH” is used to realize the communication between the wireless switch and the Aventos drive unit.

 

“SYNC” is used to synchronize 2 or more Aventos drive units (not used in PCON).

The button “COLL” (collision) is not used in our implementation.

HF, HL

 

ˇ      In the state HF the drive unit can be dismounted or mounted to the mechanics.

ˇ      In the state HL, the unit is physically connected to the mechanics, this is the normal operating state.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Aventos door switch

The door switch is used to operate the Aventos servo unit. By pushing the button, a wireless connection between button and servo unit is realized and, depending on the actual state, the door will be opened or closed respectively.

Synchronize

 

Usually, the synchronization between drive unit and switch is done during installation of the unit.

 

If the synchronization between switch and controller of the drive unit is lost, the procedure should be executed.

 

 

ˇ      The synchronization procedure assigns the switches to the controller unit.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Replace the battery

ˇ      If the LED in the switch is flashing, the battery needs to be replaced

 

Battery type:       CR 2032

 

 

ˇ      If the battery was replaced, synchronization between switch and aventos unit might be required!

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

 

 

 

 

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 (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!

 

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

Bus extenders

 

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.

Power LED

 

The power LED is lighting if the power is supplied to the Pannoramic scanner (the power cable is connected; the Mains switch and the Housing Switch are switched on).

 

If the power LED is not lighting

 

 

 

 

If the power LED is flashing

 

If there is a shortcut inside the scanner, the power supply is switched off by overload!

Every 200 ms the power supply will switch on itself and tries to supply the output voltages. This behavior makes slightly flashing the power LED; the fan may rotate.

  • Switch off the mains power of the power supply and measure with the ohmmeter the resistance between the positive and the negative pole of the output voltages 24V, 12V and 5V of the power supply “tdk Lambda”. (Do not measure the +pole in relation to ground, because the voltages are ground independent!)
  • If the resistance is 1 or 2ohms only or nearly 0 ohm, the defective (shortcut) output is found.

 

  • Remove the power output connectors of the “Power distribution and switch board” and switch on the power supply again and measure any output voltage of the power supply. 
  • Remove the Power input connector of the “Power distribution and switch board” and switch on the power supply again and measure any output voltage of the power supply.
  • Remove the power output connections of +24V of the power supply “tdk Lambda” and switch on the power supply again and measure any output voltage of the power supply.
  • Remove the power output connections of +12V of the power supply “tdk Lambda” and switch on the power supply again and measure any output voltage of the power supply.
  • Remove the power output connections of +5V of the power supply “tdk Lambda” and switch on the power supply again and measure any output voltage of the power supply.

 

If the shortcut disappeared, measure the resistance of the disconnected paths / wires with the ohmmeter against the negative pole of the appropriate output voltage or reconnect the appropriate connections singly, separately to find the faulty path.

 

 

 

 

 

 

 

 

EEPROM

 

The EEPROM stores the scanner specific parameters and these are collected in the files MicroscopeConfiguration.ini and MicroscopeSettings.ini. To ensure an always proper functioning of the scanner, the content of the EEPROM should be updated after adjustments are done or units are exchanged and parameter values are modified. The EEPROM is a part of the USB controllers PCB.

ˇ   To update the content, the EEPROM should be cleared with the service program.

ˇ   If the scan software is started and the EEPROM is empty, the content of the appropriate *.ini files will be written automatically from the HDD into the EEPROM.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1.      Start the program “SlideScannerService.exe”.

2.      Click in the field “Clear EEPROM” of the selector menu.

3.      Answer the dialogue with “Yes”; then the EEPROM is cleared.

4.      Exit the service program with “EXIT”

5.      Start the program SlideScanner.exe; the *.ini-files will be automatically saved from the appropriate HDD folder into the EEPROM during startup of the program.

 

 

 

 

 

 

 

Compressed content of the EEPROM

 

The compression of the EEPROM content is required since the software version 1.16, because there are newly implemented parameters and the capacity of the EEPROM is limited to be 2kB.

ˇ       By compressing the content, memory space is won.

 

In systems, delivered with the version 1.16 the modified handling of the EEPROM content will not be noticed by the user; the files “MicroscopeConfiguration.ini” and “MicroscopeSettings.ini” staying on the HDD in uncompressed form.

ˇ       If the EEPROM content is written, the files “MicroscopeConfiguration.ini” and “MicroscopeSettings.ini” will be compressed before these are stored in the EEPROM.

ˇ       If the EEPROM is read, the content will be uncompressed before it is stored as file “MicroscopeConfiguration.ini” and “MicroscopeSettings.ini” on the HDD.

 

If an upgrade is made (from the version 1.15 to the version 1.16) the content in the EEPROM is uncompressed but the version 1.16 expects a compressed content; therefore:

 

Before you are installing the software version 1.16

ˇ       Make sure; the content of the files “MicroscopeConfiguration.ini” and “MicroscopeSettings.ini” is the most recent content on the HDD.

ˇ       Save these files to a save place

Install the software version 1.16

ˇ       Start the program “SlideScanner.exe” first time.

ˇ       The compression of the EEPROM content will be done automatically.

 

 

 

 

 

Mechanical shutter

 

The mechanical shutter is used to cover the condenser optics during the Fluorescent scan session and other, not brightfield illuminated scan sessions.

 

The shutter mechanics was removed from the focus unit (in relation to previous scanners) and the shutter motor is placed onto the scanner plate from beneath.

 

ˇ      The possible movement of the shutter guide is approximately 110º and this is defined by the number of steps, executed between shutter on to shutter off and vice versa.

 

 

See also:       “Shutter mechanics”, “Focus unit”, “Mechanical shutter” and “Shutter sensor”

 

 

 

 

Define the shutter open and closed position by setting the values of the sensor in [Motor steps] in the file “MicroscopeConfiguration.ini”.

 

 

 

 

ˇ      Check the correct values with the service program!

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Immersion liquid feeder

 

The immersion liquid feeder is used to spend drops of distilled water onto the cover slip of the tissue to be scanned with the 40x immersion liquid objective.

 

The distilled water is filled manually into the pipette and will be spend automatically by the use of the stepper motor before the scan process starts.

 

The stepper motor has a resolution of 200 full steps/revolution (3200 micro steps) and is used to drive the spindle and so the plunger.

X-Y-Z-motor control electronics

 

 

 

 

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

 

  • The power supply and the control of the addressable unit are realized via the Bus connector.

 

 

 

 

 

Darkfield illumination connector

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

 

ˇ      The connection to the DFP illumination unit is realized with the pins 14 ~ 17 of the connector “CON1”

 

 

 

 

 

 

 

 

 

 

 

  • The X-, Y-, Z-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.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Motor cable 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.

 

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 with the service program.

 

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

 

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

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

 

Important

ˇ      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.

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

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

Background (preview) brightfield illumination

 

The preview illumination consists of 6 LED’s and is used to illuminate the scan area of the slide and makes so the sample visible for the preview camera.

The preview illumination exists as a 0R version only.

The output for the preview illumination is driven by a current generator. The intensity of the backlight can be adjusted in the range between 1 and 255 (maximum) in the service program only, 0 means the backlight is switched off. The parameter is removed since the software version 1.15 from the file “MicroscopeConfiguration.ini” section [PreviewAndBarcodeScanning].

Barcode illumination

 

The “Tray Sensor” and the “Slide Sensor” are realized with Hall elements.

  • If the south pole of a magnet is over the Hall element or the north pole on the opposite side, the switch is closed and this state is recognized by the software.
  • If the polarity of the permanent magnet is inverted or a magnetic field is not present, no action occurs.
  • The sensors are so implemented, that the south pole of the permanent magnet stays over the sensor surface if the action position is reached.

 

 

 

ˇ      The sensor position is often adjustable. For adjustment procedures see the appropriate chapters.

ˇ      The sensor does not need maintenance.

Address coding

 

Because the sensor is used in a bus system (I2C), the sensor needs an address; the address have to be A0=A1=0.

 

ˇ      Other address combinations may be used in other systems or in further solutions.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Fan

 

Type:                                   ebmpapst 4412 F/2

 

Power:                                12V-DC 440mA; 5.2W with spinning sensor (operating range = 8V- to 15V)

 

Max spinning speed:       2700 rpm

 

By control of the fan’s voltage via the PIC on the “Power distribution and switch board”, the spinning speed of the blades will be affected; and so the air quantity, blown into the scanner.

 

 

 

 

The fan speed can be calculated by the following formula:

Fan speed = (2700 / maximal speed value) x actual value.

 

In the example on the right the fan speed is:

Fan speed = (2700 / 255) x 26 = 275 rpm.

Shutter sensor

 

Coupler type:           H22L  Data sheet

 

 

 

The light path of the sensor is broken if the sensor flag is moved against the limiter.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Sensor construction

 

If the flag of the shutter sensor stays in the optical path of the photo-coupler, the optical path is broken; this is also the Home position of the mechanical construction.

To change the shutter position from on to off or vice versa, the stepper motor is rotated by a predefined number of steps.

 

 

ˇ      The Home position is identical with the position “Condenser cover on; (shutter closed)”

ˇ      To operate the shutter, the rotor of the stepper motor is rotated by about 350 steps.

 

 

A mechanical limiter ensures, that the stepper motor can not be moved in negative direction,

 

By adjusting the shutter clamp position and the sensor clamp position, defined requirements are fulfilled.

Switch “Housing Switch”

 

The Housing Switch puts the power supply into running mode if the pins “Brown” and “White” are shorted.

ˇ       The voltage is about 15V- DC.

ˇ       The polarity of the cable connectors is unimportant.

 

 

 

 

 

The LED is driven by the 12V- output of the power supply TDK-Lambda.

 

ˇ      The polarity is important!

Housing Switch relay

 

 

 

ˇ      The relay is used to invert the Housing Switch’s action!

 

ˇ      3 = open:                   Power is supplied

 

ˇ      2 and 3 short:           Standby (power off state)

Trouble shooting

 

If the standby connector is disconnected from the Housing Switch’s logic and the power is supplied to the TDK-lambda, the power supply should run continuously and all output voltages should be present!
