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.

Note about EMC regulation: the generic emission standard
EN50081-2 (title: Electromagnetic compatibility - Generic
emission standard - Part 2: Industrial environment) sets that
“Where a relevant dedicated product or product-family EMC
emission standard exists, it shall take precedence over all
aspects of this generic standard”.
The equipments described in this manual have been classied
as industrial, scientic and medical (ISM) radio-frequency
equipments and the related standard for the emission is the
EN55011 (title: Limits and methods of measurement of radio
disturbance characteristics of ISM equipment.)
With reference to EN55011 standard, this equipment is inclu-
ded into Group 2 (Microwave generators, Thyristor command
equipment, Welding equipment, Induction heating equipment
or machine, Microwave industrial oven, etc.), Class A (indu-
strial environment): for this reason this equipment shall not
be used in the residential, commercial and light-industrial
environment.
The SM1150x and TM030, when properly installed, complies
with the limits of radio disturbance characteristic of a Group2,
Class A equipments as stated by EN55011.

SM 1150
Handling Warnings
The SM1150x 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 (17.3 kg=38 lbs).
General Description
The SM1150x is able to supply the power required by a
magnetron type NL10230 or equivalent, with nominal power
of approx. 3,000 W @ 2.45 GHz.
The power output can be adjusted continuously, from 10 up to
100%, using an external analog signal or by means of the
panel controls.
The unit, in addition to power the magnetron, has several
features and commands to control and power the magnetron’s
accessories.
The power supply is built in a self-ventilated 19” wide rack, 3
HE high, with a front panel comprising (see drw):
- a main switch [1];
- LED status lamps [2];
- a 4 digits display showing a working parameter, i.e. the
output power, or the alarms codes, also performing the funtion
of parameters viewing and setting, as well as status mode
displaying [3];
- 3 push-buttons for parameters settings having the meaning of
“scroll down”, “escape”, “enter” [4];
- a rotating knob to adjust the chosen value [5];
- pull off handles.
The power supply is designed to guarantee stable, correct and
safe operation, and offers the following special features:
a) it has a powerful CPU which controls the parameters and
the working mode; the CPU has also 2 serial communication
ports, one RS 232 to allow the upgrade of the software, the
second for future implementation of a eld-bus.
b) it is equipped with a circuit capable of detecting the
overvoltage on the magnetron (“moding”, detecting operation
at frequencies other than the normal operating frequency or
damage or end of the magnetron life). 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). This feature allows to
cut out the output in less than 1 ms.
The SM1150x has been developed to power and monitor our
remotable microwave head type TM030.
The SM1150x unit may be used also to power microwave
generators (heads) developed by others manufacturers under
condition that they are electrically compatible.See the electri-
cal specications of the unit on the next pages.
The SM1150D has been designed for US main line 3x208V,
while the SM1150T is for European system 3x400V: both
models accept wide line uctuations.
The reduced height of the rack (only 3 HE, corresponding to
133 mm) allows to use small cabinet, even in big plant: i.e.
in a standard cabinet with an height of 2 meters, arranged to
receive 19” racks, up to 12 SM1150x units may be easily
installed.
The user must provide a proper cooling ow: the cooling air
enter into the unit from the right side, it passes through the
internal circuits and components, then it goes out from the
back. The intake air ow is approx. 120 mc/h.

Equipment maintenance
Cleaning
Cleaning of air lter: verify once a month. In case you need to
remove dust then proceed as follow:
- remove main line from the unit
- remove the cover
- use pressurized air from inside to outside for short time: do
not exceed or you may damage the fan
- install the cover and then power-on again.
Fuses replacement
To replace the fuses on rear panel proceed as follow:
- switch-off the main breaker on front panel or whatever device
is provided to remove main line from the equipment;
- unscrew fuseholder cap;
- replace the fuse with a new one with the same electrical
characteristics;
- inspect also the fuseholder: if it’s oxidated or it has burned
point then replace it;
- install the fuseholder cap and screw tight.
For the fuse value look at chapter “Fuses spec”, pg 5.
Equipment installation
The SM1150x cannot operate on a bench: it must be installed
into a proper cabinet like a commercial 19” standard enclo-
sure.
The equipment is intended for industrial use only, not for
laboratory use, and user must respect the wiring norms and
prescriptions as described into next paragraph (“Wiring
instruction”).
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 for, at least, 3/4 of the total depth.
Usually two “L” shaped supports on each side of the equip-
ment, having a dimension of mm 10(h) x 30(l) x 2 (thick) 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 the main line. This safety precau-
tions 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.
Note that each equipment has its own fan which intake approx
120 m³/h: the outlet of the exhaust air is on rear panel, the
inlets on the right side (looking at front).
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 depth of 800 mm
(32”);
2. allow free intake of the cooling air from the side of the cabi-
net and exhaust air from back panel throu the top of the cabinet
or the back side;
3. in case of ambient air with high degree of dust and moisture,
install a proper air conditioner; if you cannot do this, then you
have to use suitable air lters and instruct the user about their
cleaning;
4. provide a separation between the air intake duct and the air
outlets, in order to avoid air-recyrculating;
Handling instructions
The equipment weight is 17.3 kg (38 lbs). 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 the original package or use
a wooden case and a proper ller: movement of the equipment
inside the package must be avoided.
Warning for handling: use handles only for help 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 SM1150 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
using pin 4 (see the wiring diagram at page 20).
II) Connect the ground screw on panel rear (indicated by
“ground” symbol) directly to the remote microwave generator
head by a separate yellow/green wire gauge 2.5 mm².

SM 1150
III) The main supply, 3 x 208V or 3 x400V must be provided
through connector #1: connect phases according to schematic
at page 20, the connector’s pins can house wires with gauge up
to 4 mm².
IV) The connector #2, with 14 pins, brings the head’s signals
to the equipment. Use wires with max gauge of 1.5 mm², refer
to wiring diagram at page 21.
V) The connector #3 is the high voltage output and must be
connected to magnetron’s cathode, usually marked with the
symbol “FA” on the magnetron’s teminal. The voltage value is
near 5 kV .Use a proper insulated cable with working voltage
>8 kVdc and minimum gauge of 0.25 mm²; protect the wire
with sheating (armoured if appropriate).
Assemble the wire into plug according to professional rules.
The reliability of the equipment starts from the h.v. connec-
tions.
ALTER may supply the HV cable with lenght on request.
VI) The connector #4 provides the power supply for the
lament transformer (usually located near the magnetron), the
magnetron fan and a warning lamp. Use wires wih max gauge
1.5 mm². Refer to wiring diagram at page 21;
VII) The “D” type female connector #5 has 25 pins and brings
the I/O signals to the equipment. We suggest to use a shielded
ribbon cable. Refer to wiring diagram at page 22.
VIII) The “D” type male connector # 6 has 9 pins and is the
RS485 serial port on the standard version of the equipment. It
will be used fo future implementation of a eld-bus (like the
CANbus).
IX) The “D” type female connector RS232 has 9 pins and it’s
a standard serial port, useful to allow upgrade of the software
from a PC. Look the pin-out at pg 23.
X) The user must provide external cut-off device, to protect the
SM1150 from short-citcuit and thermal runaway; this external
protection device must allow to switch-off the main line for
maintenance operations.
XI) The external circuit breaker must be a 3-poles breaker and
must comply the norm EN61010-1.
XII) The external circuit breaker must be in close proximity of
the equipment and within easy reach of the operator.
XIII) The external circuit breaker must be marked as the
disconnecting device for the SM1150.
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
Before power-up the equipment you must be sure to have pro-
perly connected (look at the chapter “Wiring Instruction” for
any doubt), then set the front panel breaker in “ON” position,
marked with “1”; to switch-OFF set it to “0”.
Once set to OFF (position “zero”) wait at least ve 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 has always left in ON
state): the OFF state, between two consecutive ON state, must
last ve seconds minimum.
At power on the unit enters into “POWER-ON” state for few
seconds to performs some controls, then goes immediately
into “STAND-BY” and here stays until the “lament heating”
command is switched ON.
It’s also possible to enable permanently the “lament heating”
command: in this case the SM1150 performs the lament
heating immediately after the “POWER-ON” state, but only in
absence of alarms.
At the end of the heating cycle the unit enters in “READY”
mode: the power supply may power the magnetron, which
generates microwave, only when it will receive the enabling
command.
Any tipes of alarms force the unit to exits from “READY”
state and enters in “ALARM” state.
In absence of alarms the power supply may be left in “Ready”
continuously: when it receives the enabling command (ON) it
enters into “RF-ON” state and generates output power, when
the enabling command is removed (OFF) the unit comes back
to “READY” state.

SM 1150
Working Modes
The working capability of the SM1150x depends from its
“working status”: it has several statuses with different meaning
and functionality. The logic ow of these statuses is showed on
the bottom drawing.
These statuses (or modes)are:
POWER-ON: it goes in this mode at power-on, when the main
breaker is set to 1: the CPU performs some controls, displays
the name of the unit (“1150”) then the software version (i.e.
“V2.01), and after few seconds, the unit enters in Stand-By
mode.
STAND-BY it’s a waiting state, the unit is powered but not
ready as the magnetron lament is not powered; the display
shows “STBY”, all the working parameters can be setted from
Operator Panel; the unit enters in Stand-By from the previous
Power-On state or from a Reset state.
The unit exits from Stand-by and goes to Preheating only
if there aren’t alarms, the Interlock chain is closed and the
HIBERNATE command is OFF.
PREHEATING it’s a temporary state, driven by a timer, to
allow the lament to be heated. The display shows “PREH”.
Entrance in this mode is done by an external command or self-
starting after the end of Power-On state. When the timer is
elapsed the unit goes in Ready mode.
READY it’s a waiting state, the display shows “RDY”. The unit
waits the enabling command to generate power to the magne-
tron. The magnetron lament has been heated.
The unit may last in this state as long as needed: it exits auto-
matically in case of alarms or when the
”lament heating” command is removed. It goes to next “MW-
ON” when the enabling command is set ON.
MW-ON starts microwave emission at the presetted power
level. The display shows alternatively the name of the choosen
unit (“CURRENT” or “%POWER” or “POWER” or..) and its
value, while the led “MW ON” is lighted up.
The unit exits from this mode in case of:
* the enabling command is set OFF: enters into Ready state, or
* ALARM presence: the unit goes to Stand-by, or
* the INTERLOCK chain is open: it goes to Stand-by again.
ALARM in this mode the output power is immediately shut-off
as well as the lament.
The alarm type is showed on the display, alternatively with the
word “ALAR”.
The unit may exits from the Alarm mode, to enter into the
Reset Waiting mode, only when the alarm cause is removed.
RESET WAITING: the unit enters in this mode when the alarm
cause is cancelled and the enabling command is still present
(ON).
The unit exits from this condition, and enter in Reset mode,
only when the enabling command is switched OFF.
RESET: It’s a temporary state, driven by a two seconds
timer. When the timer is elapsed the Reset state end, and the
SM1150 enters automatically in Stand-By mode.
The working condition is indicated on the display.
Look at the diagram for the working mode logic.
Meaning of external command.
HIBERNATE: has value ON/OFF. If ON the magnetron’s
lament is not powered and the SM1150 goes into Stand-by
mode.
In OFF the unit makes lament heating and, when the related
timer is elapsed, enters in Ready mode.
If a user don’t like to use the Hibernate function, he may not
connect it: the system then detect it as in OFF condition.
POWER ENABLE: has value ON/OFF, but its effect is related
also with the Hibernate command as follow:
a) in OFF state -and HIBERNATE is OFF- the unit performs
lament preheating and goes in Ready mode but does not
generate output power, even if the reference signal is >0;

b) in OFF state -and HIBERNATE is ON- the unit is in Stand-
by mode but does not generate output power, even if the
reference signal is >0;
c) in ON state -and HIBERNATE is OFF- the unit waits the
end of preheating timer, if not yet elapsed, then starts to gene-
rate output power;
d) in ON state -and HIBERNATE is ON- the unit is in Stand-
by mode but does not generate output power, even if the
reference signal is >0.
POWER SET: it’s an analog input value and has the meaning
of “percent” of the output power.
When this value is lower than 9% of full value the unit does
not generate any output power, when >9% the unit generate
power proportional to signal value.
The signal can be 0-10V, 0-5V, 0-20mA depending on hard-
ware setting of internal jumpers located on the CPU board
(look at the related drawing to nd them).
The output power can also be considered:
a) linear to the anodic current generated, or
b) linear to electrical output power (V * I), or
c) linear to forward r.f. power when the related feedback signal
is available from the process cavity.
INTERLOCK: has value ON/OFF. When in ON state the serie
of the hardware safety contacts is closed and the CPU light-up
the related Interlock OK led; in OFF state the led is Off and the
unit goes in Stand-by.
User Interface
At power on the 4 characters display shows the name of the
unit (“1150”) then the software version (i.e. “V100), and after
few seconds, the unit may enter in the working mode the unit
had at Power-Off only if the related parameter is set in this
way, otherwise the unit enters in Stand-By mode.
The unit, throu the display, informs the user of its working
mode displaying the abbreviations SBY or RDY or PREH.
At the end of the temporary lament preheating cycle (PREH),
the unit enters into the mode set by user and gives the fol-
lowing informations:
Control Mode: the parameter to be displayed (Power or Cur-
rent or Voltage or...) and the parameter’s name.
The parameter can be set throu the parameters table, position
zero.
Alarm Mode: type of alarm, alternating its name (lock at the
alarms list) and the word “ALAR”.
Programming Mode: depending on the selected level (look at
the next par.) may be displayed the Parameters Name or the
Parameter: in the latter case it may be possible to modify the
value using the digital potentiometer.
Buttons meaning
To enter on Programming mode press ESC button, then with
TAB button (the button with the arrow) it is possible to run
over all the parameters and with the ESC button, or after a
period of 10 seconds idle, you may exit from Programming.
When you are set on a Parameter with the ENTER button you
go to second level and view its value (numeric or alfanume-
ric).
This value can be modied by the potentiometer (which is a
digital encoder), but the new value is stored only pressing the
ENTER button once again.
When positioned at second level, pressing the ESC button will
bring you to upper level without saving any variation.
Look at the next drawing about the “Control menu congura-
tion”.

Software specications
At present the following versions of software have been distri-
buted:
- ver. 1.04 (V104) see the menu cong. at page 12
- ver 2.01 (V201) to ver 2.05 (V205) see the menu cong. at
page 11.
Main Characteristics of ver. 1.04:
The version 1.04 has a complex menu organization, with all
the functions than can be reached and selected by means of the
front panel commands only. In addition the Ver. 1.xx allows to
choose between 5 different control modes of the output:
1- Open Loop control: the reference signal sets the anodic
current and the control loop is performed only by hardware,
the CPU does not execute any control. I.e.: 1V = 90 mA, 5V
= 450 mA, 10V = 900 mA. This mode is equal to the control
mode of any unit without CPU (like the SMx45, SM1050,
SM1180): if the anode voltage does not vary then the power
is costant. The precision of the control is driven only by
precision/tolerance of the hardware.
2- Current Loop control: the reference signal sets the anodic
current and the control loop is performed also by the CPU.
I.e: 1V = 90 mA, 5V = 450 mA, 10V = 900 mA. If the anode
voltage does not vary then the power is costant. The precision
of the control is improved by the CPU which reduces hardware
drift for temperature modication.
3- Forward Power control: the reference signal sets the r.f.
forward power and the feedback signal should come from a
power sensor installed on the load cavity or waveguide.
I.e: 1V = 300 Wrf, 5V = 1500 Wrf, 10V = 3000 Wrf. It is useful
only if the feedback signal from the power sensor is true and
quite stable.
4- Power control: the reference signal sets the electrical
output of the power supply unit: the CPU reads continuously
the anodic voltage and adjusts the anodic current to keep the
output power constant.
I.e: 1V = 500 Wdc, 5V = 2500 Wdc, 10V = 5000 Wdc. The
precision and repeatability of the output is within 1% of full
scale.
5- Table control: the reference signal sets the electrical power
needed by the magnetron to get a presetted r.f. power. It is
useful to linearize the r.f. power with reference to the signal.
The “Table” is a set of 20 values of electrical output power that
has the effect to produce the 20 corresponding r.f. power by the
magnetron: intermediate values are calculated by the CPU with
linear interpolation. The 20 r.f. values start from 300 (Wrf)
up to 3000 W, with steps of 150 W (300, 450, 600, 750....): at
each of these steps corresponds a DC power that the unit has to
produce.
The SM1150 has a “default” Table (20 prestored values) that
can be used at any time and is not erasable by the user: in addi-
tion the software allows to load customized values that may be
used instead of those of the default Table.
To customize the Table it’s required to have a power meter
connected to the microwave cavity and then to select a table
step, adjust the power with the panel knob till the power
meter’s reading is the same. See more details on the Menu
Descriptions.
Main Characteristics of ver. 2.01:
The version 2.01 has a simplied menu organization and
the default control mode is the Table mode. The other two
control modes available, Open Loop and Forward Power, can
be selected only by means of the remote control with a PC,
connected thru the serial port RS232, and the specic program
“FrontPanel” distributed togheter with the unit. See the rele-
vant paragraph “The FrontPanel program”.
For the basic explanation of the control modes see the previous
paragraph about characteristics of the ver 1.xx
With reference to the “Control Menu Conguration” at page 11
there are the further explanations of the symbols and names;
the numbers enclosed in bracket [ ] into description refer to
the small numbers associated to names or functions on the
drawing. The description apply to drawing of the version 1.04
too.
[1, 2, 3, 4, 5, 6] WORKING MODE: see “Working Mode” para-
graph at page 8.
[7] DISP: entering this menu you select what value the unit
DISPLAYS between the following [8]:
POW DC power (Watt)
%POW Percent of output power
FPOW Forward Power (Watt)
RPOW Reverse Power (Watt)
CURR Anodic Current (mA)
VOLT Anodic Voltage (Volt)
Once selected the measured value is displayed only when the
unit is in MW-ON state.

[28] TMR: entering this menu you access to internal timers
[29]: ON timer: it’s enabled only when the lament is hot
(Ready mode): the value can be resetted by user but the system
holds information of the reset.
The CPU makes a round value to tens of hours, but the time
count has the accuracy of the minute. Max value displayed is
99.99 (=99,990 hours)
[30]: RDY timer: it’s enabled by presence of main line and
cannot be resetted by user.
The CPU makes a round value to tens of hours, but the time
count has the accuracy of the minute. Max value displayed is
99.99 (=99,990 hours).
[32] MODE: entering this menu you access the Control
Mode, enabling the type of control
MANU (Manual): the unit is controlled by the
panel commands, i.e. if you want to adjust the
power by panel knob
EXT (External) the unit is controlled by exter-
nal command, i.e. if you are supplying com-
mands from a PLC
REMO (Remote) the unit is driven by serial port or
CanBus
[36] VERS: entering this menu you get the release number
[37], i.e. V201 (for version 2.01)
[54] CAL: entering the Calibration menu you access to custo-
mize /verify the Table [55] or modify the Efciency value [62]
or select the Default Table [61]
[55] TABL: entering this menu you may modify the Table.
The Table consists of 20 values of linearized output power the
unit will reach to match the reference signal.
The unit has a default Table that is stored during nal
tests at Alter: from vers. 2.01 the unit uses, as standard at
Power-ON, this default Table.
Customizing of the Table: you need a power meter measuring
the forward r.f. power on your system.
The measure is needed to linearize the whole system as, in
principle, twice the dc power supplied to magnetron does not
mean twice the microwave power delivered to the load.
Once entered into TABL menu, the software shows you xed
numbers, starting from 300 - with increment of 150 - up to
3000: these are the 20 steps you may customize. These num-
bers represent the desired microwave power (i.e. 300 = 300
Wrf).
At every step is associated and memorized a corresponding
d.c. power that the SM1150 will ignite to the magnetron to
produce the desired microwave energy.
You may skip forward and backward, leaving them as they are
or modifying all or just few.
To modify conrm with ENTER button but be careful: this
procedure requires the SM1150 to produce power and the
microwave generator will produce, consequently, microwave
energy.
Warning: if the power supply is in MW - ON state but does
not produce microwave energy because the reference signal is
zero, once you push the ENTER button, from TABL menu,
then the SM1150 will produce output power and you may
adjust at any level of power, once you are entered into a step,
simply rotating the encoder knob on the panel
I.e.: suppose the rst step 300, which is 1/10 of the full range
and also corresponding to 1V of reference signal, has stored a
default value of 500 Wdc, and the third step 600, correspon-
ding to 2 V of signal, has stored a default value of 1000 Wdc:
if you’d like to verify and, in case, to modify them, you have:
a) to enter into TABL menu (press ENTER from
CAL menu)
b) to enter into the 300 step (press ENTER again)
c) to see the stored dc power value press ENTER
and the unit will produce energy: the display shows
you 500 (Wdc, the stored value)
d) read from your power meter the microwave
energy: suppose it’s close 300 W, then you decide to
leave the step as it is: press ESC
e) you are back, the display shows you the number
300 (point b)
f) reach the third step (600) with the TAB and
then press ENTER
g) repeat point c): the display shows you 1000
h) read the power meter: it shows close to 550
Wrf and then you decide to correct it

SM 1150
i) rotate the encoder knob on panel till the power
meter shows you the value of 600 Wrf and conrm
with ENTER. The display will show you the new dc
power needed to obtain that rf value: suppose 1100.
l) use ESC to leave the procedure.
You have customized the Table: when you’ll apply a reference
signal of
- 1 V you’ll get a microwave power of 300 W: the SM1150
ignite 500 Wdc into the magnetron,
- 2 V you’ll get a microwave power of 600 W: the SM1150
ignite 1100 Wdc into the magnetron.
- 1.5 V = 450 Wrf = 800 Wdc.
[62] EFF: entering the Efciency menu you may modify the
visualization of the power: it represents the percentage factor
to display the power. It has effect on visualization only. If you
set 100 the power displayed is the electrical power of the unit;
if you select a value close to 70 it gives you the indication of
the microwave power produced by the whole system.
[61] DEFA: entering the Default Table menu, if you conrm
the OK? question pressing ENTER you reset the Customized
Table, if any, and load the Default Table.

1) Reverse and Forward power: the two signals shows the Forward and Reverse power supplied to the SM1150, coming
from external measurement circuits generally located on the MW generator (head).
2) Output Power: both signals represent the electrical output current (V x I)
3) Off: the monitor signals are switched-off
4) Anodic voltage and current: on pin 2 the signal represents the Anodic Voltage; on pin 3 it represents the Anodic
Current.
The monitor signals are ltered through the internal CPU and can’t follow fast variation.

Software upgrading
The software stored on the CPU can be upgraded to a newer
version thru the RS232 serial port provided on the unit, with
simple operation and an external PC.
To upgrade you need:
- a serial cable with 9 pin D type connectors, one male on the
equipment side, the female for the PC side. Wiring of con-
nectors must be 1:1 (pin 1 to pin 1, pin 2 to pin 2, etc.);
- the program “FlashPro32” to run under your PC: ask a copy
to Alter or download the latest version from the web site at
www.altersystem.com
- the new version of software you want to upload into the
SM1150 (a le with extension .hex: usually the latest version
is available also from our site but you have to ask whether you
may have advantage or not)
Upgrading procedure:
I) switch OFF the SM1150 - (Enable signal must be OFF)
II) connect the serial cable to PC serial port and to RS232
serial port on the SM1150
III) remove the cover
IV) nd the CPU board installed on the front panel and loca-
lize the programming switch and the jumper as indicated.
Switch ON the SM1150
V) insert the jumper into the 2 pins and move the arm switch
as indicated: The CPU is ready to upload the new program into
its “ash” memory: this will cancel the existing program
VI) run the FlashPro and download from the PC the new sof-
tware: it will takes few minutes and FlashPro will advise once
completed.
VII) The CPU’s display may show random pattern: don’t care
VIII) when the procedure has been completed, remove the
jumper and place it into the original position and move back
the switch arm
IX) close the cover
X) switch ON the SM1150: one of the rst messages should be
the new version number.
