2 Introduction
Bruker’s sub-cooled magnets are monitored and controlled by the Bruker Magnet Pump
Control 2 (BMPC/2). To maximize reliability and up-time, the BMPC/2 features redun-
dancy of several components of the sub-cooling technology, most importantly the sub-
cooling pump. As the pump is subject to wear, BMPC/2 operation is based on an appro-
priate backup and a cyclic replacement scheme.
Figure 2.1: The Bruker Magnet Pump Control 2
The shipment of the BMPC/2 comprises three sub-cooling pumps. Each of those pumps
alone is sufficient for normal sub-cooling operation and can operate as default pump. A
second pump acts as backup pump. The default pump and backup pump are installed
in the BMPC/2. The third pump serves as spare pump, and is supplied as a stand-
alone unit.
In normal operation (Automatic Mode), the BMPC2 permanently monitors the default
pump. In case of a failure of the default pump, the BMPC/2 automatically switches over
to the backup pump. The switchover also can be done manually.
In case of such a failure, the pumps are rotated in a cyclical fashion: The pump that was
originally the backup pump continues to be operated as the default pump. The failed
pump must be replaced by the spare pump which is then operated as the new backup
pump inside the BMPC. Finally, a new or refurbished sub-cooling pump specifically
qualified for BMPC/2 operation must be procured from BRUKER to ensure that a spare
pump is again available for the next exchange.

10 Z31823_00_08
In addition to the monitoring and control of the pump system the BMPC/2 also monitors
the magnet status and the main cryogenic system parameters. The monitoring system
also features an alarm function.
The main functions include:
• Monitoring of the magnet status and the most important cryogenic system parame-
ters.
• Monitoring and control of the pump system.
• Alarm system.
Bruker part numbers:
• Standard BMPC: MC5300
• Aeon BMPC: M136266
• Double-Rack BMPC: M147753
2.1 Modes of Operation
The BMPC/2 can be operated in two different modes, manual or automatic. The modes
of operation are discussed in detail in the chapter "Principles of Operation" on page 41.
2.2 User Interface
The BMPC/2 is controlled by a software user interface. This interface contains three
user levels:
1. User - Standard User Level.
2. Administrator - System Administration and Configuration Level (typically accessi-
ble to the lab responsible).
3. Service - For Bruker Service Personnel.
There are five different screen display modes and four different work display modes
available within the user interface. These various software interface displays can be con-
figured individually by the System Administrator or by Bruker Service. Refer to the chap-
ter "Software" on page 47 for an overview of the user interface.

Z31823_00_08
2.3 Parameter and System Configuration Overview
The BMPC/2 system is pre-configured by Bruker service personnel during installation.
The configuration parameters for the alarm and voice box systems can be adjusted by
the System Administrator or by Bruker Service. The contact details of the alarming sys-
tem should be kept up to date by the Administrator (lab responsible). Information for the
Administrator on how to configure the system is available in the chapter "Configuration
(Administrator)" on page 79.
2.4 Alarm and Notification System
An integral part of the BMPC/2 system is the Alarm System and Voice Box System.
The Alarm System is needed for the supervision of the magnet system. A description of
this system is available in the chapter "Alarm System" on page 67.
The Voice Box System is the telephone interface that is used for an alarm sequence or
for requesting a remote status report. An overview of this system is available in the
chapter "Voice Box System" on page 71.
2.5 Additional Information Available in This Manual
The following chapters have been included in this manual to provide additional informa-
tion for the user:
•"Hardware Overview" on page 19
•"Maintenance and Cleaning" on page 117
•"Setup and Diagnostics Tool" on page 75
•"Maintenance and Troubleshooting" on page 119

3 Safety
3.1 General
The following safety guidelines are relevant for the Bruker Magnet Pump Control 2
(BMPC/2) unit:
• Service and maintenance should only be accomplished by qualified personnel.
• Only personnel trained on the use of the BMPC/2 should operate the unit.
• Read this manual completely before operating the BMPC/2. Pay particular attention
to any warning references made.
3.2 Intended Use
The device has been designed and constructed solely for the intended use described
here.
Intended use also includes compliance with all specifications within this manual.
Any use which exceeds or differs from the intended use and the instructions of this man-
ual shall be considered improper use and may impair the safety of operation. No claims
of any kind for damage will be entertained if such claims result from improper use.
The BMPC/2 is intended for sub-cooling and controlling of Bruker ultra high field mag-
nets. It is not intended for other purposes or for sub-cooling of non-approved magnets.
Users must follow all instructions in this manual and observe all local or regional rules
and regulations.
NOTICE
To avoid switching off the device by accident the BMPC/2 circuit breaker is not
directly accessible for the user. The circuit breaker of the UPS unit can be used to
switch off the BMPC/2 unit.
Disconnect the mains power supply before servicing the unit.
NOTICE
Small quantities of liquid helium are present in the Joule-Thomson refrigeration unit
inside the magnet to which the BMPC is connected. In some non-standard opera-
tional scenarios, this liquid volume can evaporate rapidly, and lead to a slight
increase of the pressure in the pump inlet. The pump inlet is protected by a bursting
disc installed in the pump line between the BMPC and the magnet. This bursting disc
limits the maximum overpressure to 2 bar.

14 Z31823_00_08
If you have questions about how to use the BMPC/2, please contact the supplier.
3.3 Safe Handling of Cryogenic Substances
NOTICE
Please keep this manual for future use.
NOTICE
The BMPC pumps gaseous helium at room temperature from the magnet. The
pumped helium is expelled into the atmosphere, into a helium recovery system, or, in
case of Aeon systems, circulates in a closed loop. The maximum flow rate is on the
order of 3 SLPM. Helium is a noble gas. It is nontoxic and inflammable. In case of no
or only partial helium recovery or helium recirculation the helium concentration in the
vicinity of the BMPC can increase. To avoid this, the BMPC must only be operated in
well ventilated areas. No gases other than helium are released from the BMPC.
WARNING
Cryogenic Substances
To avoid injury, cryogenic substances must be handled and stored in a safe manner.
Refer to the magnet manual for information on the safe handling and storage of
cryogenic substances.

3.4 Analog Telecommunication Safety
NOTICE
Analog Telecommunication Safety Warnings
Before servicing, disconnect this product from its power source and telephone net-
work, and adhere to the following safety warnings:
Never install telephone wiring during a lightning storm.
Never install a telephone jack in wet locations unless the jack is specifically
designed for wet locations.
Use this product with UL and cUL listed computers only.
Never touch uninsulated telephone wires or terminals unless the telephone line
has been disconnected at the network interface.
Use caution when installing or modifying telephone lines.
Avoid using a telephone during an electrical storm. There may be a remote risk of
electrical shock from lightning.
Do not use a telephone in the vicinity of a gas leak.
CAUTION: For USA and Canada a modem cable must be used with the following
properties: 2 x RJ11 - 6P4C - min AWG 26 - AWM 20251, UL or CSA listed.
