Pre-installation requirements for Microstar (Ultra)
and FR591 generator
Information to prepare the installation of the Rotating Anode X-ray
generator.
Check also the pre-installation requirements of the equipment (goniometer)
delivered with the generator.
General
It is assumed that the installation of the system is conducted by Bruker
AXS. Please send the checklist to Bruker AXS once the preparations are
ready. Only after approval of the checklist by Bruker AXS the engineer
will start the installation work.
Packing and shipping
The system consists of several crates, pallets and boxes. The exact
number of crates may vary. The heaviest crate is 210 x 125 x 125
cm 560 kg. The largest crate is approximately and 260 x 110 x 65 cm. After
unpacking all parts will fit through a standard door (90 cm).
-
Upon receipt please check the number of crates against the packing list.
-
Inspect for visual shipping damage.

Table model generators can be extended by additional elements (cubicle;
75 x 130 cm, weight 110 kg).
-
The generator requires a firm floor. You are advised to obtain installation
permission from your local building authority, fire brigade, safety council
and insurance broker.
-
Relative humidity: maximum 80% if <31°C, decrease linearly to 50%
at 40°C
Power requirements
-
Mains voltage: 200-240 V (phase - neutral), 347-415 V (phase - phase),
±10%, 50/60 Hz ±5%.
-
Three phase Y (WYE or star) supply with a five wire connection,
3 line, 1 neutral and 1 ground. A four wire connection plus external ground
is also suitable.
-
-
Additional a separate earthing connection is required to which a
safety earthing line is connected.
-
Mains current surge :
-
Microstar :3 x 25 A
-
FR591 9 kW version : 3 x 35 A
-
FR591 18 kW version : 3 x 63 A

-
The power cable is 4.5 meters outside the cabinet, 5 conductor cable,
each conductor is 6 mm² (Microstar) or 10 mm² (FR591). It must
be connected to the wall isolator or plug of a mains connector. With a
fixed mains terminal an isolator must be installed in a convenient position
near the equipment which enables the generator to be completely isolated
from the electrical mains supply for maintenance and service.
-
The generator is earthed (grounded) at one point and from there
the ground is internally distributed.
-
If the supply neutral is grounded it should have the same potential
as the earth point on the generator.
-
No RCD (earth leakage relay) should be installed, because of the
earth current of the internal filter. A delayed RCD, like from Hager
could be possible. The right settings must be found by trying the lowest
values.
-
Grounding resistance should be less than or equal to 0.16 Ohm.
Step-up
/ down mains transformers
When the local voltage between phase and neutral is not between 200
V and 240 V an additional 3 phase transformer with secondary star point
is required. Because the energy consumption is not of sinusoidal nature,
the rating of the transformer should be 2 - 2.5 times the consumption as
indicated above. The following ratings are recommended:
-
Microstar: 15-19 kVA
-
FR591 9 kW version: 38 - 47 kVA.
-
FR591 18 kW version: between 58 - 73 kVA.
Cooling Water
-
Specification:
-
Maximum power:
-
Microstar: 2.7 kW
-
Microstar Ultra: 2.2 kW
-
FR591: X-ray tube (6-18 kW) + 1.5 kW
-
Inlet water temperature :
-
Microstar: 15-25 ºC, optimal 18-22 ºC.
-
FR591: minimum 15 ºC (too cold causes condensation and fatal corrosion).
-
Temperature variation in time:
-
With 6 cm Cu optics (Montel 200): not more than 3 ºC (+/- 1.5 ºC).
-
With Mo optics or Helios optics (i.e. with 10cm optics): not more then
1 ºC (+/- 0.5 ºC).
-
Microstar Ultra: not more then 0.8 ºC (+/- 0.4 ºC).
-
Minimum cooling water flow rate (for the High Brilliance Anode) with a
inlet water temperature of 20 ºC:
-
Microstar: 10 litres per minute.
-
FR591 9kW: 14 litres per minute (for more extensive data see the Technical
User Manual).
-
FR591 18 kW: 20 litres per minute (for more extensive data see the Technical
User Manual).
-
Pressure : 2 - 6 Bar (beween input and output).
-
The wall behind the system must have suitable cooling water supply connections
with stop cocks. When the generator is to be cooled from a closed recirculating
in-house water supply it is advised to fit a stop cock between the supply
and return lines. This enables you to isolate the generator from the water
supply without affecting other water consumers.
-
-
For the internal (secondary) cooling system 25 litres of demineralized
water is needed.
-
Flexible hoses with couplings must be provided, with an inner diameter
of 25 mm and of sufficient length to reach the generator with a extra length
of about two meters (for inside the cabinet). These hoses will be connected
to the generator by the installation engineer.
-
When mains water supply is used, it is strongly recommended that a water
filter is fitted.
-
Coolers which can supply the cooling water:
Water cooler
-
A water to air recirculating cooler should be outside the generator room,
to avoid heat and noise problems.
-
When a cooling water unit is included in the delivery it must be determined
before installation where the unit must be installed and how the connections
to the generator will be made.
Compressed Air
Supply
When a goniometer with an air pad system is used then a flow of oil
free compressed air of 100 L / min. at a pressure of 4 bar is required.
Nitrogen connection
To avoid long pumping after a cleanup of the vacuum system, we recommend
dry nitrogen to be used, whilst the vacuum chamber is exposed to the atmosphere.
The consumption is very low, so that a 10 litres nitrogen bottle is sufficient
for one year. A set of good quality pressure reduction valves with accurate
low pressure ( 0 - 0.3 bar) manometer is required.
Interlock
The equipment has a provision for an external interlock (contact) to
be connected into the control system to prevent X-rays being generated
unless the interlock is closed. If an interlock is desired, this should
be communicated with Bruker AXS before starting the installation.
Generators without radiation
enclosure
When no radiation enclosure is used, the generator must be located in
a separate X-ray shielded room.
-
The cable from the operator panel outside the cabinet is approx. 4 m.
Maintenance
Good and timely maintenance is essential for a reliable operational
life. All components should not be altered, omitted or replaced by other
than identical factory supplied genuine replacement parts. It is the buyer's
responsibility that maintenance is carried out on a regular basis according
to the maintenance protocols as provided by Bruker AXS and as supplied
with the system components. Neglecting to do so will void the warranty.
Routine maintenance protocol is included in the operation instructions.
Non-routine maintenance should preferably be carried out by service engineers.
