Alter’ policy about Reduction on Hazardous Substances (RoHS) and Waste
Electrical and Electronic Equipment (WEEE)
Law Reference
• Directive 2002/96/EC of European Parliament (WEEE)
• Directive 2002/95/EC of European Parliament (RoHS)
• Decreto Legislativo D.L. n. 151 – 25/07/2005 (WEEE and RoHS)
Starting from September 2005 Alter has set the rule to accept only RoHS compliant components from its Suppliers.
At the present date of 15 May 2006, 90% of components in our stock is RoHS compliant.
The components still not compliant were hold in stock and still used for two reasons:
• there is not the same or equivalent product RoHS compliant, or
• the product is a spare part for equipment produced and put on market before 1st July 2006.
Alter Risk Assessment on RoHS
Of the six substances forbidden from electronic equipment (Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent
Cromium (Cr-VI), Polybrominated biphenyls (PBB), Polybrominated diphenyl ethers (PBDE)) only two are used in
Alter’s current manufacturing process, Pb and Cr-VI, of whose lead is the more important.
Mercury: not present, never used
Cadmium: was present as part of alloy on relay contact. We are using relay RoHS compliant now.
Never used as anti-corrosion coating on metal parts.
Pbb & Pbde: may be present in some cables and insulating material in the past.
We are using only RoHS compliant suppliers and products now.
Cr-VI: is used as anticorrosion layer on aluminium part. We are evaluating alternative coating. It is still
present within the limit of 0,1% in weight as set by Directive.
Lead: it is largely used as an alloy for welding of electronic parts. We are already using alternative alloys
lead-free, but as we still have components that cannot be soldered without lead, we have to use some
lead-alloy for welding. At present there are still general concerns about reliability over the time of a
soldered electronic joint done without traditional Sn/Pb alloy. We are putting any effort on reducing
lead weight within 0,1% of products as set by Directive.
Important information to User about disposal, recycling, reuse of this electronic
equipment at the end of its useful life (WEEE Directive).
According to Annex IA and IB of EC Directive 200/96/EC this equipment is not included on the list of categories/
products covered by the Directive (as a matter of fact it does not perform a function alone, must be included into a
larger process equipment and it’s for stationary use).
Nevertheless we invite the User to respect the following Directive rules:
• this WEEE is not a municipal waste and should be collected separately according to rules of your country
• the symbol means that this WEEE cannot be disposal in the same place and in the same way like
municipal waste
• this WEEE may present risk for environment as well as for person in case of disposal in unauthorized
place, due to content of hazardous substances
• for disposal of this WEEE in unauthorized area the User may be charged with a ne or prosecuted by
law.

Handling Warnings
The SM1180 has two handles on the front panel to help
unpacking and handling operations: never use only the
handles to lift the equipment but support the weight with
an appropriate base on bottom!
The handles do not withstand the off-center weight of the
equipment
(SM1180T: 36.5 kg = 80 lbs, SM1180D/U: 40 kg = 87 lbs).
General Description
The SM1180 is able to supply the power required by a magne-
tron with power up to 6 kW (which correspond to 1100 mA
of anodic current), meeting the specications set by the tube
manufacturer.
This manual describes the features of the following:
- version 4: standard version for YJ1600 magnetron
- version 5: standard version for H3881 magnetron
- version 54: special version with separate aux voltage and
magnetron YJ1600
- version 55: special version with separate aux voltage and
magnetron H3881
The description apply to any versions unless specied diffe-
rently.
The power output can be regulated continuously using an
external analogue signal or the panel potentiometer where
provided.
The power supply is built in a self-ventilated 19” wide rack,
7HE high, with a front panel comprising:
-a 4 digit display (upper) showing a working parameter, i.e. the
output power, or the alarms codes
-a 4 digit display (lower) showing the reverse power (if the
necessary external accessories are provided)
-several signalling LED for working conditions
- inlet air lter
The power supply is designed to guarantee stable, correct and
safe operation, and offers the following special features:
a) all the versions has the option to be driven with a reference
signal 0-10 V (or 0-5 V or 0-20 mA), while into versions 2
and 3 may be used also the front potentiometer.
b) it is equipped with a circuit capable of detecting the over-
voltage on the magnetron (“moding”, detecting operation
at frequencies other than the normal operating frequency or
damage or end of the magnetron life).
The circuit accepts a short period of overvoltage (about 2
seconds) in the switch-on phase, this is normal, especially if
the magnetron reaches the end of its life or the lament power
supply voltage is low.
The circuit also ensures that the power supply is switched
off if the high voltage cable is disconnected, or if the heating
lament fails.
c) it has a circuit capable of detecting an earth current on the
anode circuit, super imposing the normal current circulating in
the magnetron (which returns to earth).
The circuit can pick up current from a resistance of 5 Kohm,
in parallel to the magnetron, irrespective of the current circu-
lating.
The circuit also intervenes in case the high voltage short cir-
cuits to earth, or there is a reduction in the working voltage of
the magnetron.

SM1180 & TM060
The SM1180 has been developed to power and monitor our
remotable microwave head type TM060.
The SM1180 power supply may be used also to power
microwave generators (heads) developed by others manufactu-
rers under condition that they are electrically compatible. See
the electrical specications of the unit on the next pages.
The reduced height of the rack (only 7HE, corresponding to
310 mm) allows to use small boards, even in big plant: i.e. in a
standard board with an height of 2 meters, arranged to receive
19” racks, up to 5 SM1180 units may be housed.
The user must provide a proper cooling ow: the cooling air
enter into the unit from the front panel, it passes through the
internal circuits and components, then it goes out from the
rear panel.
The intake air ow is approx. 200 m³/h.
The rear panel comprises the following:
- a 7 pins socket for main supply (Conn. #1)
- the fuses holders
- a 14 pins socket for the signals (Conn. #2)
- a 7 pins socket to power the remote microwave head (Conn. #3)
- a 9 pins socket for the signals coming from the remote
microwave head (Conn. #4)
- a 4 pins socket for the high voltage output (Conn. #5)
- a 2 pins terminal to allow remote head “INTERLOCK” func-
tion (Conn. #6);
if you don’t use this feature then let the jumper between the 2 pins
unchanged (= connected)
- a 2 position key switch to enable the panel potentiometer;
pos. 0 = potentiometer disabled; pos. 1 = potentiometer enabled
- a “READY” contact (closed when the unit is ready to gene-
rate anodic current).
- the outlet of the cooling air.
The rear panel of the version 54 and 55 comprises also the
following:
- a 3 pins socket to power the auxiliary section (Conn. #7)
vers. 4/5
vers. 54/55

Specs of version 54 and 55 only:
The connector #7 has been added, on version 54/55 only, to
power the control section of the psu, in order to have the latter
separated from main line power (provided through Conn #1)
The Conn #7 powers the remote head (fan, lament transfor-
mer, lamp) and the internal fan of the psu.
The user must provide an external switch to power/unpower
the control section of the SM1180 vers. 54/55.
Two 6A fuses (F1 and F2) are provided to protect the 230V
(nominal) circuit.
A max current of 1.4 Arms (@ 230V) must be provided in
normal operation, while 3.2 Arms is the max surge inrush
current, due to initial cold lament heating, every time the
lament is switched off (i.e. by removing the power input, or
by interlock chain opening).
The main line voltage can still be switched ON and OFF
through the front panel breaker.
WARNING: to avoid alarms it must be adopted the correct
sequence of switch-on
Enable signal ON
OFF
Power section ON
OFF
Control section ON
OFF
Correct sequence:
1) Enable signal: OFF
2) Control section: POWER-ON
3) Preheating time: 30 seconds
4) Power section: POWER-ON
5) Enable signal: ON
No problem arises if the Power section is switched Off (or
ON) while the Enable signal is OFF, but powering down the
Power section while Enable is ONleads to A_4 alarm, after
10 seconds, as the system doesn’t sense the power anode
current.
Also powering ON together the Power section and the
Enable can cause an A_2 alarm

Intake air ow: approx 200 m³/h
Cleaning of air lter: at least every 200 hours in a normal
industrial environment or more frequently for dusty envi-
ronment. Before removing the lter switch-off the unit!To
remove the lter simply raise the front grid with a tool and
pull.
Equipment installation
The SM1180 cannot operate on a bench: it must be installed
into a proper cabinet like a commercial 19” standard enclo-
sure.
The equipment cannot operate cantilevered, it must be safely
xed inside a cabinet by means of screws on the front panel
(which is provided with 4 holes) and supported by means of a
proper frame on the bottom.
Usually two “L” shaped supports on each side of the equip-
ment are suitable for that purpose.
The rear side of the equipment must be protected by a xed
panel which can be removed only by means of tools or by a
door with security micro-switch: when the door is opened the
micro-switch must shut-off at least the enabling signal of the
equipment or the main line. This safety precautions must be
taken to avoid operations on rear fuses or on connectors while
the unit is still powered.
Special attention must be taken on designing the cooling air
ow in case of stacking several units into the same cabinet.

SM1180 & TM060
Note that each equipment has its own fan which intake approx
200 m³/h: the outlet of the exhaust air is on rear side of the
equipment.
When designing a board to house several units we recommend
to adopt the following design criteria:
1. use a standard 19” wide enclosure with a minimum depth of
600 mm (24”);
2. allow free intake of the cooling air from the front of the
cabinet;
3. in case of ambient air with high degree of dust and moisture,
you need a deeper cabinet (at least 32”) to assemble the units in
the middle of cabinet and install a closed door. In this way you are
providing two vertical ducts (inside cabinet) with exit from top or
bottom; the front one is for air inlet, the rear one for exhaust air;
4. provide a separation between the air intake duct and the air
outlets, in order to avoid air-recyrculating;
Consider a ow rate of 200 m³/h for each power supply.
Connectors and fuses specications
The following specications refer to panel connectors and
installed fuses. Please note that all the connector plugs must be
ordered separately with the p/n 44/SET1180 or 44/SET1180D.
The set includes also the single pins and spare fuses.
Handling instructions
The equipment weight is 36.5 kg (80 lbs) for SM1180T and
40 kg (87 lbs) for SM1180D/U. Always lift from the bottom
and use an adeguate rugged support to avoid personal injury
and damage to equipment itself.
In case of shipping package with wooden case and a proper
ller: movement of the equipment inside the package must be
avoided.
Warning for handling: use handles only for helping during
installation. Never use handles to lift the rack: the handles
don’t withstand the off-center weight of the rack!
To lift always lean the rack over a proper supporting base.
Wiring instructions
The SM1180 must be installed and serviced only by quali-
ed personnel acquainted with the regulations covering the
application. For safety operations the following rules must be
adopted:
I) the equipment must be grounded through the connector #1
