2Unpacking and installation
2.1 Receiving the goods
The Shipping container and the Power Supply should be thoroughly inspected for signs of
obvious physical damage immediately upon receipt.
All materials in the container should be checked against the enclosed packing list.
DANFYSIK A/S will not be responsible for shortages against the packing list unless notified
immediately.
2.2 Instructions for unpacking
The Power Supply is shipped in reinforced cardboard.
If the equipment is damaged in any way, a claim should be filed with the shipping agent, and a
full report of the damage should be forwarded to DANFYSIK A/S or our local agent/-
representative immediately.
Upon receipt of this report, you will be issued instructions for the repair, replacement or return
shipment.
Please include the Model no, Type no, Serial no, and Order no for the Power Supply on any
communication with DANFYSIK A/S or our representative.
2.3 Installation requirements
During installation of the Power Supply, local rules and regulations for electric power supplies
should be respected and the following conditions and installations should be available.
* A normal, dust free room with humidity not above 80 % and a room temperature within
15 to 40 centigrade.
* Three-phase Mains voltage switched and fused, + neutral and protective earth.
* Ground connection according to the local authority regulation and the requirements for
the equipment.
* If applicable, cooling water supply at a temperature within 15 to 35 centigrade.
Differential pressure: Min. 1 bar.
Max. inlet pressure: 12 bar.
Please see specification sheet chapter 1.2 in this manual for actual figures for this power
supply.
* For cooling of our power supplies and magnets we recommend the use of demineralised
water or pure water with an electrical conductivity of less than 10μS/cm. This reduces
the electrolytic corrosion to a minimum.
Adding pure ethylene glycol to cooling water with no other additives should not affect
the electrolytic corrosion. However, it will reduce the thermal conductivity of the
coolant. A percentage of 40% glycol reduces the conductivity by approximate 30%. We
would recommend not using more than 25% corresponding to an approximate reduction
of thermal conductivity of 17%. It may be necessary to increase the water flow in the
power supply.

MAGNET POWER SUPPLY SYSTEM 9100
11
DANFYSIK A/S - DENMARK.
No other additives should be used.
During operation, the conductivity of the coolant should be checked regularly. A few
days operation with water of poor quality can cause more corrosion damage than during
several years‟ operation with good quality water.
2.4 Installation
Before and during installation of the Power Supply, the following points should be checked /
carried out.
* Check that the main voltage and frequency matches to the specified and labelled
requirements.
* Check that screw connections from the output terminals are tightened.
* Check that all screws on D-sub connectors are tightened.
* If the magnet is provided with a thermal breaker connect the contacts to external
interlocks and +24 VGND (Ground for +24 V)
* Unused external interlocks shall be connected to +24V ground (Ground for +24 V pin
12, X112 or to pin 11 +24V_Ext_GND if +24V_Ext, pin X8 is used for interlock
supply)

3Operating instructions
This chapter outlines the procedure and precautions for the operation in local and in remote
control mode.
It identifies and describes the controls and indicators on the M-Panel Graphical.
Also the programming of the remote lines is described.
Instructions for initial remote line set up are given in chapter 3.3.
3.1 Switching on
When precautions have been checked in accordance with chapter 2.3 and 2.4, the power supply
can be switched on.
Immediately after the Power Supply is switched on, a start up screen appears on the M-Panel
and displays which control module is connected and makes a self test and scans for a text table
has been downloaded or not.
After approximately 5sec., the panel is ready for use. The remote line is ready for use after
approximately 3 sec.
Make sure that the time between switching the control power - OFF and - ON again is at least 5
sec. to ensure a correct cold start (initialization of the Power Supply).
- Select LOCAL CONTROL mode at the CMD-menu. "LOC" text appears in the display
(1).
To turn the power supply ON for the first time, it is recommended to activate it in the
LOCAL CONTROL mode as this is the easiest way to get started.
- If any Interlocks are set, push the "Reset" button (8).
Remove the faults if the Interlocks are not reset.
- Set the desired output current by use of the SET-menu.
- Switch the Main power "ON" (3).
- The READY LED (6) illuminates, when the output current is equal to the preset value
within a given accuracy typically +/-200ppm.
- Switch the main power "OFF" (5).
3.2 Operating with the Manual Control Panel
The MANUAL CONTROL PANEL (M-Panel Graphical) is an interface module that are used
with several Danfysik Magnet Power Supplies including SYSTEM 9100.
The SYSTEM 9100 comes with a M-panel as standard. It can however also be delivered with a
display board. This has two 5 digit 7 segment displays for voltage and current. LED indicators
for POWER ON, FAULT and READY. With this display board, the System 9100 can be
operated remotely from a PC, or by connecting an M-panel to the local port situated on the
back side of the system 9100. The M-panel can be connected and disconnected from the Power
Supply without affecting the power supply operation. Communication between the Power
Supply and the M-Panel is by a serial link, and may be physically located at the Power Supply
or up to 400 meters away from it.

MAGNET POWER SUPPLY SYSTEM 9100
14
DANFYSIK A/S - DENMARK.
3.2.1 Main power ON / OFF and interlock RESET
The basic function on the M-panel is to turn the power supply ON / OFF and to RESET
pending interlocks. All controlled from a single button. For further information about the
button locations, see chapter 3.2.3 Front Panel Control.
Setting the output current is done through one of the pull down menus described in the next
chapter.
When the power supply is ON the LED in the button area will illuminate.
When the power supply is OFF the LED in the button area will illuminate.
If an interlock is present the LED inside the RESET button will illuminate.
Pressing the RESET button will clear the interlocks that are not due anymore.
Hint: If an interlock is present, it will also be represented on the display at the lower right
corner.
Hint: The color of the LEDs can be reprogrammed to illuminate green, red or
“orange”.
3.2.2 Using the Manual Panel Menus
This chapter shortly describes the use of the M-Panel Graphical. The menus themselves will be
described later.
The user interface of the M-Panel Graphical is based upon pull down menus. To display the
menus simply press the MENU button (if not already standing in the Menu window).
To prevent unnecessary hiding of the main display (set current, output current and voltage) the
pull down menus are always displayed left aligned. In other words, it is the menu bar that rolls
over the pull down region.
With visible menu bar, activating the “” or “” arrow buttons the menu bar always displaying
the selected pull down menu at the left side will rotate. At the bottom right is a help text,
showing what the selected pull down menu group is used for. To select one of the lower menu
items the “” or “” arrow buttons must be used. Also here a help text at the bottom right of
the display will tell what the selected menu will do. If a menu has a sub menu it will be shown
with a right arrow to the right of the menu text. This sub menu can be accessed by pressing the
right “” arrow. Having found the desired menu it can be entered by pressing the “” Enter
key (The selected menu is shown inversed). If the chosen menu has a parameter to be edited a
pop up window will be shown with the parameter (as the set current menu), if the menu only
contains data to be shown a pop up window will be displayed with the data (as in the Interlock
menus) or if the menu is a command (as the REMote or the LOCal) then the task will be
executed immediately and the cursor will stay at its position. A pop up window is exited by
pressing the “” Enter key again.
The above in short, one can say: The menu bar is entered with the MENU key end exited again
with the MENU key (back to default window). A pop up window is entered with the “”
Enter key and exited again with the “” Enter key. Just like parentheses in equations.

MAGNET POWER SUPPLY SYSTEM 9100
15
DANFYSIK A/S - DENMARK.
As usual any rule has exceptions and these are:
- If there is no need for parameters after activating the “” button “Stand alone menu” there
is no need to press the “” button again. [One ”” equals “( )” ]
- Pressing the MENU button while editing a parameter will abort the operation. [Regret the
operation as an “ESC”]
- Remotely changing the command status to Remote will automatically abort any local
operation.
Hint: To ease the use, the “” Enter key may be used instead of one of the arrow keys in
some situations- i.e. if the action is given anyway. Eg. Standing on the top of a menu
the “” will do the same as the “” key or when standing in a menu containing a sub
menu the “” will do the same as the “” key. (Interferes a bit the mathematical
parentheses idea; but is fast to use in some cases)
Hint: Pressing the MENU key the first displayed menu will either be the SET or the INTL
menu. The last one if at least one interlock is present. This minimizes the number of
buttons to be pressed to “MENU”, “” , “” for setting the output current or the
same key sequence to se the active internal interlocks. Actually the three lowest
vertical keys pressed from bottom up.
Changing a parameter is done with the arrow keys. (See also the help text at the bottom right of
the display). A cursor, shown as the digit inverse, marks the digit to be manipulated. Pressing
the “Enter” key ends the editing.
Hint: Holding either the “” or the “” keys pressed when editing a number the auto
increment function will start.
If no menus have been used within 5 minutes, then the display will automatically be switched
back to the opening window aborting any current operation (security reason).

3.2.4 The Display
The display is a multi purpose graphic window to the user. The window can be divided into
three groups:
Default window:
The default window is shown below. If the Operator Control Panel is unused for 5 minutes, the
Operator Control Panel will automatically enter this state. This is for security reason. Escaping
from any menu back to this default window can be performed by pressing the “MENU” button
again. Any ongoing operation will be cancelled.
Scrolling menu bar
The upper part of the display is normally used for displaying the viable top menus. In the
default window, “------ DANFYSIK ------“ will be displayed. It is called “scrolling menu
bar” because contrary to normal Windows © pull down menus it is the top menus that
scrolls with the “” “” buttons.
Pull down menu area
The pulls down menus are always shown in this area. If a pull down menu has sub menus
they will advance to the right. The second submenu will overwrite the “ Set and Output”
area.
Power supply Set and Output
Upper line displays the output current setting with six digits. After a cold start it displays
"SET 000000 ppm". When full output current is set, it displays "Iset 999999 ppm", which is
to be read as 99.9999 % of full scale. If required a setting in Ampere with six digits and a
decimal point can be adapted. This will be set at Danfysik during test or by Danfysik service
personnel.
The middle line display the actual output current with two digits. E.g. "Iout 54 %" means
that the current is 54 % of full scale. This reading is made by the internal 8 Bit bipolar ADC.
If a more accurate read out is required, the Control module can be added with a 16 Bit ADC.
The current will then be automatically displayed by six digits where the last digit always
will be zero. That is with five significant digits. E.g. "Iout 346340 ppm" means that the
current is 34.634 % of full scale. If required an output reading in Ampere with two or five
digits can be adapted. This will be set at Danfysik during test or by Danfysik service
personnel.
The lower line displays the actual output voltage with two digits. E.g. "Vout 45 %" means
that the current is 45 % of full scale. This reading is made by the internal 8 Bit bipolar ADC.
If required an output reading in Volt with two digits can be adapted. This will be set at
Danfysik during test or by Danfysik service personnel.

100 % when the bar-graph is full. The minor tics are for 5% steps and the major tics for 10%.
Each pixel represents therefore 0.5%.
Status area
The status area shows for a quick view the present control status of the power supply
These are:
- Control mode. LOCal or REMote Remote is shown inversed.
- Regulation status. ReaDY or not Ready is shown inversed and not ready as three bars.
- Main power. ON or OFF. OFF is shown inversed.
- The controlling address in a multi drop configuration. Blank if not enabled
Information area
The bottom right corner of the display is used for displaying other information. These are:
- The time taken from the SMD Control module is shown if nothing else is to be
displayed.
- INTERLOCK present if an interlock is pending. (In default window)
- STATUS present if a particular Status is pending, normally 1 transistor fault.
- Help text on the menus.

Menu Window:
Pressing the MENU button the
Menu window will appear. The
picture to the right shows the
opening window if no interlock is
present and after the “” button is
pressed once.
Editing Window:
If a value needs editing a cursor, shown as an inverted character, will occur somewhere in the
value. Somewhere because the cursor can remember its last used position. Move the cursor to
the desired position and change its
value with the “” or “” keys.
Holding the keys pressed will
initiate an auto increment /
decrement operation.
Pop Up Window:
The picture to the right shows a pop up window displaying many interlocks. The bar at the
bottom indicates that there is no further information downwards, and the arrow at the top
indicates that pressing the “”
button will display the above
listed interlocks. If a pop up
window contains values to be set,
the line to be changed will be
displayed inversed (cursor over
the line). Use the “” “” buttons
to change the value. “” & “”
scrolls between the lines. (Eg.
LED Color setup menu).
History Window:
The history window can be seen as
an oscilloscope screen with auto
scaling.
The picture to the right shows an
example history window set to
absolute scale with visible scale
units. The indicates one pixel unit.
