1.2 Description of the pressure control panels of the BM and BE series
Spectron pressure control panels are available in BM and BE versions.
BM pressure control panels are suitable for combustible gases, non-combustible gases and oxygen up to
a purity grade of 6.0. BE pressure control panels are suitable, in addition, for use with corrosive gases.
In addition, there is a distinction between pressure control panels with single-stage pressure relief from the
inlet pressure to the desired outlet pressure (type code: 55) and two-stage pressure relief (type code: 56).
While two-stage pressure relief ensures an extremely constant outlet pressure throughout the entire inlet
pressure range (from "full" gas cylinder to almost "empty" gas cylinder), with single-stage pressure relief the
outlet pressure can vary within a certain range.
4 GES_BM+BE_55+56-2U_1212.docx
Operating Manual
of the BM and BE series
1. Introduction
In addition, the outlet pressure drops in the single-stage version at switchover from the operational side to
the reserve side. This does not happen with two-stage pressure relief.
The 2U pressure control panels are two-sided pressure control panels with a switching mechanism (2U).
The switching mechanism switches automatically from the side that is currently in operation to the reserve
side when the gas supply situation requires it. The lever position of the switching mechanism indicates
which side is the operational side and which the reserve side.
All of the above pressure control panels are equipped with a process gas valve and a waste gas valve on
each side.
With regard to both the outlet to the supply line and the pressure regulator relief valve, you can choose
between two versions:
Pressure regulator with outlet adapter: the outlet and relief valve are located parallel to each other at
the top.
Pressure regulator with outlet adapter and valve: the outlet and relief valve are located parallel to each
other at the top, but there is also a shut-off valve in the outlet.
Contact pressure gauges, pressure transducers and pneumatically operated valves can also be configured
for each of the above versions.
1.3 Intended use
Intended use
The BM55-2U and BM56-2U pressure control panels described are intended for use with non-corrosive
gases up to a purity grade of 6.0. The BE55-2U and BE56-2U pressure control panels are suitable,
in addition, for corrosive gases up to a purity grade of 6.0. The permissible gases and pressure ranges are
specified on the type plate. Pressure control panels reduce a variable inlet pressure to an outlet pressure
that is as constant as possible.
The pressure is introduced exclusively via the process gas valve. Appropriate measures must be taken to
prevent the introduction of pressure to the pressure regulator outlet via the pipe system.
Pressure control panels without electrical components (such as a contact pressure gauge or pressure
transducer) may be used in potentially explosive atmospheres, since they do not have a potential ignition
source of their own (ignition hazard evaluated in accordance with DIN EN 13463-1).
The danger of ignition has to be taken into account with pressure control panels with electrical components.
It is imperative that this is evaluated on the basis of the documentation of the electrical components,
taking into consideration how they are incorporated into the system as a whole, in compliance with
directive 94/9/EC (ATEX 95). The user can get more detailed information on the Internet at
www.spectron.de
or directly from the customer support staff at Spectron Gas Control Systems GmbH.
Foreseeable misuse
The following operating conditions are deemed to constitute misuse:
Operation with gases that are not specified on the type plate
Use with gases in their liquid state
Operation outside of the permissible technical limit values
Failure to heed and comply with any applicable legal regulations and other provisions
Failure to follow the instructions in this operating manual
Failure to carry out inspection and maintenance work
Failure to heed the information on the type plate and in the product data sheet

2.3 Safety features
The pressure regulator of the pressure control panel is equipped with an integrated relief valve to protect
the fitting.
Note
The relief valve allows gas that has to be released as a result of an impermissible rise in the
outlet pressure to be blown off.
It does not function as the safety valve for the entire gas supply system.
Important
In the event of the failure of the pressure regulator and its relief valve, a safety mechanism
that meets the requirements of the regulations for operators must be incorporated to protect
downstream fittings, pressure vessels and pipes from excess pressure.
Danger
With combustible, toxic, corrosive and other gases that are harmful to health or the environment,
an exhaust pipe must be connected to the relief valve to take the gas away safely.
The factory setting of the relief valve must not be altered.
Possible hazard Hazard-prevention measures
Danger of death
If oxygen comes into contact with oi l or grea se, the re is
a risk of fire due to a chemical reaction.
Keep all parts that come into contact with oxygen
free of oil and grease.
Danger of death
Gas escaping into the ambient air can ign ite; there is
a risk of fire and explosion.
Smoking and naked flames are strictly prohibited
near gas supply equipment.
Danger of death
The pressure control panel may be damaged by
unauthorised changes or alterations and may no
longer work as intended. There is a risk of the sy stem
malfunctioning, catching fire or getting damaged.
No changes or alterations may be made without the
written approval of the manufacturer's authorised
technical personnel.

2. For your safety
Danger of death
If pressure control panels are used that are not
suitable for the relevant gas and pressure range,
there is a risk of a fire or explosion o ccurring as
a result of a chemical reaction.
The pressure control panel must be suitable for the
relevant gas and the pressure ranges involved.
Only use for the gases indicated on the device.
If there are no gas types specified on the pressure
control panel, you have to ask the manufacturer which
gases it can be used with.
On no account must the pressure control panel be put
into operation without this information.
Danger of death.
If the pressure control panel is operat ed with
combustible, toxic or corrosive gases, the gas can
be released into the environment when the relief
valve opens.
Relief valves of pressure control panels for
combustible, toxic or corrosive gases must have
a pipe that brings the gases emitted to a safe recycling
facility that complies with regulations.
Danger of death
Gas that escapes in an uncontrolled manner indoors
can reduce the oxygen content of the air a nd be lif ethreatening.
Make sure that the outlet end of the blow-off pipe of
systems operated indoors is outdoors. In the case of
toxic or corrosive gases or gases that are harmful to
the environment in some other way, dispose of the
blown-off gas in accordance with the applicable
regulations.
Danger of death
Oxygen that escapes in an uncontrolled manner
indoors can result in a dangerous rise in the oxygen
content of the air and an increa se in t he tend ency of
clothing and other objects to ignite.
Make sure that the outlet end of the blow-off pipe of
oxygen systems operated indoors is outdoors, and do
not start a fire or ignite a flame.
Read the EIGA document SAG 79/04/E for more
information.
If the pressure control panel is used outside the
specified ambient temperature ran ge, ther e is a r isk
of the system malfunctioning, catching fire or getting
damaged.
Do not use in ambient temperatures below -30 °C or
over +60 °C.
If dirt particles get into the pressure r egulator of the
pressure control panel, this can damage it or cause it
to malfunction.
It must be ensured that no dirt part icles of any kind ca n
get into the pressure regulator. That is why a filter is
incorporated into the process g as in let of the pressu re
control panel.
If the device is not handled properly and used as
intended, this may be dangerous for the user and
others and may damage it.
Use and handle the pressure control panel only as
described in this operating manual.
If the connecting surfaces or gaskets of the fittings
are damaged or missing, there is a danger of g as
escaping in an uncontrolled manner .
Check the connecting surfaces for damage, and do
not install if the connecting surfaces are damaged or
gaskets are missing.

Operating Manual

3. Description
3.2 Functional description
The automatic switching pressure control panels of the BM/BE 55/56-2U series reduce any inlet pressure,
provided it is within certain limits, to the outlet pressure required. The pressure is reduced by the pressure
regulator used. You select which side of the pressure control panel is to be used by operating the switching
mechanism:
Lever up: the pressure regulator on the left is in operation
Lever down: the pressure regulator on the right is in operation
The switching mechanism links the pressure regulators with each other by their pressure adjusting spindles.
If you shift the lever from the upper position to the lower position, for example, this reduces the outlet
pressure in the pressure regulator on the left and increases the outlet pressure in the pressure regulator on
the right. The right-hand side is thus currently the operational side.
The automatic and interruption-free switchover to the reserve side on the left, where the pressure is set
lower, takes place as soon as the outlet pressure on the operational side (on the right) drops to below that
of the reserve side. This can happen as a result of the constant emptying of the gas cylinders on the right
and thus the falling of the inlet pressure on the operational side to under the level of the reserve side or as
a result of very large amounts of gas being drawn, thus lowering the outlet pressure on the operational side
quickly. Thus, if the reserve side goes into operation with single-stage switching panels (BM/BE 55-2U),
the outlet pressure made available by the switching panel is lower than the outlet pressure made available
by the operational side beforehand. The manual operation of the switching lever helps here: it increases
the outlet pressure of what has been the reserve side, thus converting it into the operational side, and at
the same time reduces the outlet pressure of what has been the operational side up to now. As a result,
it becomes the reserve side.
In the case of two-stage switching panels, the fall in the outlet pressure as a result of the switchover is
barely noticeable. The outlet pressure is kept largely constant by means of the second regulating stage.
All single-stage automatic switching panels have an inlet pressure gauge for each pressure regulator to
indicate the current inlet pressure. Since the pressure regulators are linked to each other on the outlet side,
only one pressure regulator has the outlet connection. The other one has the outlet pressure gauge.
Depending on the variant, up to the version with an outlet pressure of 100 bar there is an outlet adapter in the
outlet with an integrated relief valve or an outlet adapter with an integrated relief valve and shut-off valve.
The BM/BE56-2U series have a second regulating stage incorporated into the outlet. An outlet pressure
gauge and relief valve are connected to this.
Note
The pressure control panels can be equipped with contact pressure gauges. These issue
a switching signal when a specific pressure limit is violated or, in the same way as pressure
transducers, supply a current that varies continuously with the pressure (4-20 mA).
The switching signal or variable electrical current can be processed by means of connected
control units, resulting, for example, in the issue of a gas shortage alarm.
When these contact pressure gauges or pressure transducers are used in areas where there is
a risk of fire or explosion, special measures have to be taken, as described in directive 95/9/EEC
(ATEX 95). You will find more detailed information at www.spectron.de
.
Another option is to equip the pressure control panel with pneumatically operated valves.
These require a pneumatic control pressure of between a minimum of 5.5 bar and a maximum
of 8 bar.

3.3 Technical data
Note
The technical data can be taken from the Spectron data sheet for the relevant product. If this is
not available, you can view and download it at www.spectron.de
.
The maximum inlet and outlet pressures and the gas type are indicated on the type plate.
3.4 Connection options
Inlet pressure connector: 1/4" NPT female thread, generally equipped with a stainless steel
compression fitting for 6 mm pipes
Outlet pressure connector: 1/4" NPT female thread
Relief valve: 1/4" NPT female thread
Extension connector: 1/4" NPT female thread
3.5 Changing the supply side
Step Activity
1 The position of the lever indicates which side the gas is drawn from:
Switching lever up – gas is drawn from the gas cylinders on the left-hand side:
The outlet pressure of the pressure regulator on the left is set higher than that of the pressure
regulator on the right.
Switching lever down – gas is drawn from the gas cylinders on the right-hand side:
The outlet pressure of the pressure regulator on the right is set higher than that of the pressure
regulator on the left.
If the handle is positioned horizontally, the two pressure regulators are set to the same outlet pre ssure.
2 The gas cylinder pressure on the preselected side falls below the outlet pressure of the reserve side:
the reserve side takes over the job of supply ing proce ss ga s to th e conne cted co nsumers with out
interruption.
With single-stage switching panels, the outlet pressure falls markedly when there is an
automatic switch from the preselected operational side to the reserve side. When the
switching lever is operated, the reserve side is raised to the normal outlet pressure level
and thus becomes the operational side.
Two-stage switching panels keep the pressure very largely constant.
4 Move the switching lever to increase the outlet pressure again on the reserve side that has now
become the operational side.
5 Change the gas cylinder on the side that has now become the reserve side.

3. Description
3.6 How the operating pressure is adjusted
The pressure control panel is set at the factory to a specific nominal operating pressure or average
pressure (with the switching lever positioned in the middle). If necessary, this nominal operating pressure
can be changed.
Step Activity
1 Position the switching lever (item 1) horizontally and turn it anti-clockwise to unscrew it.
2 Loosen the grub screw (item 2) using an SW3 Allen key.
3 An SW6 Allen key can now be used to adjust the working pressure by turning the hexagon socket
head screw (item 4) below the switching lever.
Turn clockwise to increase the pressure level.
Turn anti-clockwise to reduce the pressure level.
4 After adjusting the pressure level, re-tighten the grub screw (item 2), screw the switching lever
back on, and position it to preselect the side from which the gas is to be drawn.

Note
The gas type must be specified on the pressure control panel. If the gas type is not specified on
the type plate, it must be done using the attached gas-type adhesive labels before the device is
put into operation for the first time.
Warning
Only the gas type for which the pressure control panel was ordered may be specified on it.
4.2 Installing the pressure control panel
Note
You can find instructions on how to install the pressure control panel in the installation manual
MA_BM+BE.
You can view and download this at www.spectron.de
.
4.3 Putting the pressure control panel into operation
Important
Before putting the equipment into operation for the first time, the entire pressure control panel must
be purged via the process gas valve right up to the consumer. It is imperative to adhere to the
direction of the gas flow when doing this. You must not purge counter to the usual direction of flow
(from the tapping point to the pressure control panel), since this can flush debris resulting from the
installation work, for example, back into the pressure regulator.
The connecting thread and connecting surfaces of the gas cylinder valves and the sealing rings of
the manual connectors of the pigtails must be checked to ensure they are in perfect condition.
Pigtails with manual connectors are connected to gas cylinder valves without the need for a tool.
Pigtails with flat faces for tightening (generally for corrosive or toxic gases) are tightened with
a suitable spanner until they are gas-tight.
Always turn shut-off valves as far as the stop when opening or closing them.
Step Activity
1 Ensure that:
The gas type is specified on the pressure control panel.
All protective caps have been removed.
The installation has been carried out properly.
The pigtails and other connecting points have been checked for leaks.
The waste gas valves are closed (the red marking is visible in the handwheel window).
The pressure regulator is released.

Operating Manual
of the BM and BE series
4. Operation
Step Activity
2 Position the switching lever to specify which is the operational side and which is the reserve side.
3 Pressure purge the system:
Slowly open the gas cylinder valves on the left and right.
Slowly close the gas cylinder valves on the left and right.
Open the waste gas valve on the left and right to relieve the pressure, and then close it again.
Repeat at least three times.
If the inlet pressure is low, the process has to be repeated more often.
4 Slowly open the gas cylinder valve(s).
5 Slowly open the process gas valve.
6 Check the entire pressure control panel and all detachable connections for leakage.
7 Gas can now be drawn.
4.4 Changing the cylinder
Important
Once it is put into operation, both sides of the panel must always be connected.
Before replacing a cylinder, always turn the switching lever with the "In operation" display to the
side from which gas is currently being drawn. The arrow indicating the reserve side points to the
side of the pressure control panel on which the gas cylinders are now to be replaced.
It is extremely important to move the switching lever, since otherwise once the empty gas
cylinders have been replaced with full gas cylinders and the process gas valve has been
opened, this side would take over the gas supply function again.
The reserve side would then remain the reserve side, but its gas reservoir would not be
100% full.
Each time you change the cylinder, check that the gasket is in perfect condition and replace it
if necessary.
Note
Each time you change the cylinder, ambient air gets into the con necting part s of the system. To prevent
the gas and the entire system from being contamin ated, the con nection must be purged b efore gas is
drawn from the cylinder again. In the case o f non- toxic, non-cor rosive gase s, this ca n be don e by
means of multiple pressure purges with own gas. In t he case of co rrosive or toxic gases or gases that
are hazardous in some other way, purging must be carried out with foreign gas. The flushin g device
required for this has the designation BE55-SP. It may have to be retrofitted.

4. Operation
The procedure for changing a cylinder is describ ed below, taking the right -hand ga s cylinder by way of example:
Step Activity
1 Acknowledge the change of cylinder.
Position the switching lever with the arrow marking pointing up.
"In operation" can be read for the cylinder on the left --> which is now the supply side.
"Reserve" can be read for the cylinder on the right --> which is now the reserve side.
2
Close the right-hand gas cylinder valve and process gas valve.
3
Open the waste gas valve on the right.
Release the residual pressure in the pigtail.
Close the waste gas valve on the right.
Loosen the pigtail on the cylinder valve on the right and connect it to the new cylinder.
4 Pressure purge the system:
Slowly open the gas cylinder valve on the right.
Close the gas cylinder valve on the right.
Open the waste gas valve on the right to relieve the pressure.
Close the waste gas valve again.
Repeat at least three times.
If the inlet pressure is low, the process has to be repeated more often.
5 Slowly open the gas cylinder valve on the right.
6 Slowly open the process gas valve on the right.
7 Check the gas cylinder connection and all detachable connections for leakage.
4.5 Taking the equipment out of operation
Taking out of operation or interrupting operation for a short period
When interrupting operation for a short period, all you need to do is close the process gas valve.
The red marking in the handwheel window indicates immediately that the valve is closed.
Taking out of operation or interrupting operation for a longer period
Step Activity
1 Close all valves.
To do this, turn until you can see the red marking in the handwheel window.
2 Open the waste gas valves.
3 Any gas in the system flows out of the waste gas pipe.
4 Close the waste gas valves.
5 The pressure in the pressure control panel must be released by allowing the gas to flow away via
the consumer. It must be ensured that the indicators of the two pressure gauges are on zero [0] –
visual check.
If it has been used with corrosive or toxic gases, the entire pressure control panel must be purged
with inert gas.

5. Problems
Problem/cause Remedy
Gas is released from the relief valve.
Impermissible increase in the outlet
pressure.
Close all valves immediately.
Have the pressure control panel checked immediately by the
manufacturer or an authorised specialist company.
The pressure regulator is making noises.
This indicates a defect.
Close all valves immediately.
Have the pressure control panel checked immediately by the
manufacturer or an authorised specialist company.
The pressure regulator is frozen.
This indicates that too much gas is
being drawn.
Reduce the amount of gas drawn or – if technically, chemically
and physically possible – add a heater to pre-heat the gas.
There is a leak.
This indicates a defect in a pressure
regulator component.
Close all valves immediately.
Have the pressure control panel checked immediately by the
manufacturer or an authorised specialist company.
The outlet pressure level is unstable and
is not adhering to the usual range of
variation. This indicates that too much
gas is being drawn.
Reduce the amount of gas drawn.
It is also possible that there is dirt in the inlet filter. In this case,
the pressure control panel must be checked by the manufacturer
or an authorised specialist company.
The inlet pressure or gas cylinder
pressure of the side indicated as the
reserve side by the position of the lever
is falling.
The reserve side is also supplying gas to the down stream pro cess.
This could either be because too much gas is being drawn or
because the pressure regulator has a defect.
Reduce the amount of gas drawn. If this is not possible or if this
does not correct the problem, contact the manufacturer or have
the pressure control panel checked by the manufacturer or an
authorised specialist company.
