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

See the relevant chapter “Specs of version 54/55” at page 22,
23.
IX) the user must provide external circuit breaker . We also
suggest to install a thermal cut-off device, to protect the
SM1180 from short-citcuit and thermal runaway with breaking
capacity > 50 kA: note the unit has a magnetic circuit breaker
with a breaking capacity of 15 kA;
X) these external protection devices must allow to switch-off
the main line for maintenance operations;
XI) the external circuit breaker must be a three poles breaker
and must comply the norm EN61010-1;
XII) the external circuit breaker must be in close proximity to
the SM1180 and within easy reach of the operator;
XIII) the external circuit breaker must be marked as the
disconnecting device for the SM1180;
XIV) the connector #1 must never be used as a switch-off
device.
Failure to comply with these instructions may involve con-
siderable risks for the staff responsible for checking and
using the equipment, as well as the risk of general malfunc-
tions of the equipment itself.
Equipment operation
Power-up procedure
To power-up the equipment set the front panel breaker in
“ON” position. In case the breaker trigs to OFF then wait at
least ten seconds before setting it ON again.
This rule must be valid even in case the power is given
by an external contactor (and the panel breaker is always
left in ON state): the OFF state, between two con-
secutive ON state, must last ten seconds minimum.
At power on the unit starts the lament preheating cycle, :
during preheating the “MAGNETRON ON” led ashes twice
per second. At the end of preheating the unit is ready to start
microwave emission on command as described in the next
paragraph: the “MAGNETRON ON” led ashes 5 times per
second and the “READY” contact is closed.
Operating control
The SM1180 operation is controlled by an external command
at +24 Vdc (nominal): the voltage range may vary from 8 to 30
Vdc, common to ground, Z=2.5 kOhm.
The command signal must be wired to pin 3 of the connector
#2: if the user doesn’t have a suitable voltage generator for this
signal, then the equipment’s internal voltage generator can be
used: a voltage signal is available at pin 4 of connector #2. In
this case the user must provide an external contact closing the
circuit between pin 4 and pin 3 to enable the equipment opera-
tion. Refer to wiring diagram at page 24.
When the command is ON and the followings condition are
satised:
-the SM1180 has been properly connected to a remote
microwave head,
- there are not alarms conditions,
- the “interlock” loop is closed,
- the lament preheating has been completed, then
the SM1180 reaches the preset value of anodic current and
power-up the remote microwave head.

Display and LED meaning.
On the front panel there are 2 digital displays, one upon the
other, and on one side there are the status leds. The upper
display and leds are controlled by the main CPU (or “master”
CPU), the lower display is controlled by the secondary CPU
(or “slave” CPU).
The panel potentiometer must be enabled by means of the key
switch located on the rear of the unit: the switch avoid the
presence of both signals at the same time.
Led meaning:
POWER ON: ON when main breaker is ON and
main line present
MAGNETRON ON: FLASH twice per second during la-
ment preheating.
FLASH 5 times per second: the la-
ment is preheated, the unit is ready
ON with Ia> 50 mA.
OVERTEMP.: OFF with no overtemperature alarm.
FLASHING in case of overtemp.
inside the rack.
ON in case of magnetron overtempe-
rature.
WATCH DOG: OFF with no alarms
FLASHING in case of arc detection
(an electrical arc occured inside the
waveguide launcher and has been
detected by the arc detector)
ON : shortcircuit present.
OVERVOLTAGE: OFF with no alarms
ON : magnetron overvoltage (moding)
POWER ON (slave): ON when main line is present
MAX REVERSE: ON when the signal of the reverse
power exceeds its threshold .
Visualization modes of the upper display
(CPUMaster)
This display usually shows one of the followings (see the
function table): - anodic current (in mA), or
- anodic voltage (in Vx10), or
- magnetron power (in Wx10)
with the following exceptions:
- when you switch on: all the segments are shortly
lighted up, then appear the
word “mast” for a short time.
- during an alarm condition:
shows an alarm code (A...)
(see the alarms code table)
Visualization mode of the lower display
(CPU Slave)
This display shows the reected r.f. power (in Wx10) with the
following exception:
- when you switch on: all the segments are shortly
lighted up, then appear the
word “slav” for a short time.

Alarms coding
A--1: magnetron overtemperature
A--2: rack overtemperature
A--3: arc detection
A--4: overcurrent/undercurrent
A--5: overvoltage
A--6: head sensors (water switch or air switch or
cover sw.)
A--7: reverse power exceeding the threshold
Warning: in case of alarm the unit shuts-off the output. To
restart the user must remove the alarm condition and must
execute the reset procedure which starts a lament preheating
cycle again.
Reset procedure after alarm condition:
I) with the unit powered but not enabled to generate
microwave (the “enabling command” was OFF): hold down
for 1 second both the “+” and “-” buttons of the upper display
(master CPU). To do a remote reset procedure set ON and
then OFF: keep OFF the enabling command for at least 2
seconds;
II) the unit was generating microwave: keep OFF the enabling
command at least 2 seconds.
When the alarm condition is removed the alarm code is hold
on display till the reset procedure is executed, then the display
shows the current parameters.
The code of the alarms are present also on the signal connector
#2 as a 3 bit binary numbers as shown in the “alarms table”.
ALARMS TABLE
The 3 bit binary code is wired as follow:
- bit n° 1 (LSB): pin n°11 of the connector #2
- bit n° 2: pin n°12 “ “ “
- bit n° 3 (MSB): pin n°13 “ “ “
Buttons meaning and programming procedures
(Master CPU):
During normal operation the display shows a user dened
parameter. In addition the on-board software allows the access
to several internal parameters, such as alarm threshold and
linearization parameters, already set in factory during nal
tests.
These parameters are recorded into 28 functions, shown on the
display with the format Fnn: nn is the function number from 0
to 27.
I.e. the function F_0 allows to select which type of value is
displayed during normal operation (anodic current, or anodic
voltage or magnetron power).
For all these datas the CPU does an analog reading and then
use a calculated value with respect to a line dened during
calibration on factory.
As known to dene a line it needs two points, the rst at low
value, the last at higher value.
The “X” co-ordinates, which refer to analog reading, are self-
stored by means of a simple command, while the “Y” co-ordi-
nates, which refer to the value you want to display, must be
stored by User.
For more informations pls ask detailed informations about
“Calibration procedure of the SM1180”.

On the right side of the display are located the 3 push-buttons:
“F” to enter into programming or select a function or
conrm/exit;
“+” to increase the displayed value;
“-” to decrease the displayed value.
Note: in the next paragraph the words:
“current page” means the usual parameter and / or infor-
mation displayed during working mode;
“F_nn” means the function # nn displayed with that
format.
Viewing and modifying parameters:
(From current page of working mode)
I) Press F and hold for 2 seconds: you enter in programming
mode; the display will show F_nn.
II) Press + o - to increase or decrease nn and choose the func-
tion F_1.
III) Press again F to see the value of the parameter which is
set to 0: press + to set the value to 1.
From this point it is enabled the programming mode.
IV) Press again F to go back one step and the display will
show F__1: you are now into programming mode. Press + or
- to modify nn (function selection).
V) Press F to see the value of the function: now using + and
- you may modify this value.
VI) Press again F to go back one step: the display will show
F_nn (you are now at step “II”).
VII) Press F and hold for 2 second to exit from the program-
ming mode and to go to current page. You may exit at any
time: if none value has been modied, the previous values are
actual, otherwise the new ones are stored.
VIII) It is provided a timeout to exit from any situation: after
10 seconds without modications you exit from programming
mode and come back to current page.
Every time you go back to current page you also leave the
programming mode: F__1 is automatically set to 0.
Buttons meaning and programming procedures
(Slave CPU):
To modify the internal parameters follow the same procedure
described for the Master CPU.
Main parameters of the Slave CPU:
The value in F 7 shows the alarm threshold of the Reverse
Power (value: Watt x 10).
It is possible to x this threshold to the preferred value, also
over the value of the max forward power: in this case the alarm
will not enter in function.
The value in F 19 shows the level of the Reverse Power with a
10Vdc input signal (value: Watt x 10).
If the value of the maximum Reverse Power is measured with
an output signal different from 10V it is possible to change
with this value (F 19) the Slave CPU visualization.
Default values:
F7 (Reverse Power alarm threshold) = 300 means 3000W
F19 (max power with 10Vdc input) = 600 means 6000W

Equipment maintenance
Cleaning
Once a week inspect the inlet air lter as well as the outlet
window.
The inlet lter, on the front panel, may be taken off by means
of a screwdriver or similar tool doing raise between the lter
and the panel: before doing any operation switch off the
external circuit breaker provided to remove the main from the
equipment.
In case the equipment needs internal cleaning then proceed as
follow:
- switch off the external circuit breaker or whatever device
provided to remove the main from the equiment;
-remove the main connector #1 by rotating counter-clockwise
the external ring then pull it;
- remove cover
- remove dust with dry air
- reinstall cover: tighten all the screws
- plug the connector #1: push the plug into the socket, rotate
clockwise the ring.
