1 Getting Started
1.1 This Manual
This manual is intended to be a quick-start reference guide for Bruker service techni-
cians. It provides basic information for installing and setting up the Fourier 300 system.
Carefully read the information in this manual, as well as, the safety information
provided in the Service Manual before working on the device!
This manual provides only the basic information required for installation and set-up, for
complete information refer to the service manual.
1.2 Before You Begin
This guide assumes that the magnet has been evacuated, cooled down, and that all the
equipment for energizing that magnet is available on site.
Three test samples, two spinners and a sample gauge are shipped with the system.
• 3% CDCl3 in Chloroform (lineshape)
• 0.1% EB in CDCl3 (1H SINO)
• ASTM (C13 SINO)
To shim the magnet and perform the ATPs test you will need to bring some additional
samples:
• Urea in DMSO (Pulse Length adjustment)
• 100mg or 1g Cholac in CDCl3 (DEPT)
• Cyclosporine in C6D6 (2D Examples)
1.3 Unpacking the Console
Do not attempt to lift the Fourier console out of the carton, rather:
1. Slide the carton sleeve up and over the console.
2. Slide the console off the pallet.
The console has wheels and can be moved around freely using the handle on the back.
Retain the packaging in case the console has to be returned for repair/exchange.

1.4 Console Connections
Figure 1.1 Console Connections
1.5 External Filters
Some earlier models come with three external filters:
• Z13383 is connected to the 1H connector on the rear of the console.
• Z14331 is connected to the C13 connector on the rear of the console.
• Z00116 is connected to the C13 connector of the probe.
Later models have just two external filters:
• E1451420 is connected to the 1H connector to the rear of the console.
• E1451430 is connected to the C13 connector to the rear of the console.

1.6 Adjusting the Air Pressure
Adjust the air pressure so that the manometer in the console reads between 3.5 and 4
bar. This way the default spin and lift parameters will be sufficient to get you started.
1.7 Switching On the Console the First Time
The console has three modes:
• OFF (blue light OFF), the switch on the rear panel is set to OFF.
• STAND BY (blue light BLINKING), the switch on the rear panel set to OFF, the ON/
OFF button on the top of console is not yet pressed.
• ON (blue light ON).
It is IMPORTANT to switch the console on BEFORE switching on the PC, since the con-
sole contains the Ethernet hub, and the DHCP server will not start if a network is not
found.
1.7.1 Verifying That the Console Has Booted
This procedure takes 30-60 seconds, provided the DCHP server is already running.
There is no visual indication on the console indicating that the console has booted, but
the easiest way to check is to see if the three main Ethernet devices (main board, lock
and VTU) can be reached via ping or a Web browser. Their addresses will usually be in
the range:
149.236.99.25x
To access any of the Web server sites, the following password and user name are
required:
User: root
Password: BRUKER (in capitals!)
If you are not sure the DHCP Server is running, you can check by opening:
Control Panel -> Administrative Tools -> Services -> Bruker DCHP Server
Figure 1.2 Bruker DCHP Server

Getting Started
If you are not sure what addresses have been assigned, you can check by opening the
following file:
Bruker\Diskless\dchpd.leases
lease 149.236.99.254 {
starts 4 2010/08/19 11:08:55;
ends 2 2038/01/19 03:14:06;
tstp 2 2038/01/19 03:14:06;
binding state active;
next binding state free;
hardware ethernet 00:00:ad:11:4f:12;
uid "\001\000\000\255\021O\022"; }
lease 149.236.99.253 {
starts 4 2010/08/19 11:08:58;
ends 2 2038/01/19 03:14:06;
tstp 2 2038/01/19 03:14:06;
binding state active;
next binding state free;
hardware ethernet 00:00:ad:13:34:12;
uid "\001\000\000\255\0234\022"; }
lease 149.236.99.252 {
starts 4 2010/08/19 11:09:01;
ends 2 2038/01/19 03:14:06;
tstp 2 2038/01/19 03:14:06;
binding state active;
next binding state free;
hardware ethernet 00:00:ad:12:85:12;
uid "\001\000\000\255\022\205\022";
Once you are sure that all three devices have booted, you can start TopSpin. Normally,
the PC will come with the hardware configuration (CF) having already been carried out.
If you receive an error message stating that one or more devices cannot be found, you
may have to repeat CF (refer to Chapter 9 of the NMR Experiments User Manual).
1.8 Copying the Probe Data to the PC System
Since the Fourier system always comes with the same type of probe, there is no PICS
interface on the Fourier console. Instead a CD-ROM with the probe data is delivered
with the system. Before running EDHEAD, copy the probe.ph file from the CD-ROM to
the directory:
“conf/instr/FOURIER300”

Getting Started
1.9 Setting the Magnet to the Correct Field
The magnet is designed to be operated at 300.18 MHz, with the current in the H0 field
coil of the shim system set to zero. At this frequency the synthesizers are “cleanest” and
least likely to create spurious problems.
When the lock is powered up from a cold start, the field DAC is not automatically set.
In order to make sure the current in the field coil is set to zero:
1. Open the BSMS panel.
2. Set the field value to 2048.
3. Switch the lock to “ON” once, then switch it off again while the magnet is being
charged to the correct field and the cryo-shims are adjusted.
1.10 Setting the Spin Safety Threshold
The spin has a safety function that shuts the spin off as soon as the Lift is turned on,
either manually, or during the initialization of the sample changer. In order to do this, the
analog sensor that monitors the spinner has to be calibrated. The sensor has three volt-
ages for the three possible states:
No spinner (typically 0.1 to 0.6V)
Black (typically 0.6 to 1.5V)
White (typically 2.5 to 4.5 V)
Since the values vary between shim stacks, and also depend somewhat on the spinner
type, it is necessary to calibrate this value. Usually this only has to be done once at
installation.
1. Open the Web server of the VTU and go to -> peripheral control -> spin

Figure 1.3 Setting the Spin Safety Threshold
2. Remove the sample, or activate the sample lift, and annotate the “empty” spin volt-
age.
3. Insert, or lower the sample, and switch on the spin (either from the BSMS panel or
from the Web server).
4. Repeatedly read the spin voltage and annotate the two values that can be read
while the sample is spinning.
5. Set the “sample down threshold voltage” to about halfway between the lower of the
two “black/white” spin voltages, and the “empty” spin voltage.
Everything is set correctly when the spin does not cut off during normal operation, but
cuts off immediately when the lift is activated.
Note: The “Spin DC Voltage Counter” sets the number of times the value has to be
below the threshold, before the safety shut off is activated. It should be set to 10 to avoid
the spin cutting off with just a single bad reading.
