INTRODUCTION
ALSATOM SU MPC series electrosurgical units are made up of the following sections:
•Microcontroller section;
•HF output power section;
•Power display section (only for SU 140, 140/D, SU 140/BD);
•Handle control section (only for SU 140 e 140/D).
Microcontroller section performs main system functions: according to signals coming from HF output power
section, setting commands and monitoring circuits, it enables HF output power delivery, blocking it as soon
as control parameters are out of normal safety conditions. Driving signals for HF output power section are
delivered in this section as well.
HF output power section is composed by a mosfet push-pull configuration: throughout the HF output
transformer, it supplies HF power available in output connections. Some relays drive the waveform either to
monopolar or bipolar output, blocking HF power in not used output receptacle.
Since HF output power is higher than 50 Watts in all models, neutral plate alarm is supplied: this blocks HF
power delivery as soon as a neutral electrode failure occurs. Failed condition is displayed with a red light and
error code PPP (in 140/D and 140 only) on front panel together with an acoustic signal
SU 140/D and SU 140 models are provided with two 3-digit seven-segment displays to allow user to set HF
power in both cut and coagulation modes. Furthermore user can usespencils with pushbuttons to activate
these models, due to a circuit to allow activation for theseaccessories.
Switching the unit ON, SU MPC performs a selftest phase to check if all parameters are in safety range.
During the selftest, displays show 8.8.8. 8.8.8.,cut and coagulation activation lightsis on. Next, CUT display
shows “L“with software release for few seconds. At the same time COAGULATION display shows a digit
from 1 to 5: this means what model is (refers to the following table).
Coagulation display Code Model
1SU 140/D
2SU 140
3SU 100
4SU 50
5SU 140/BD
Schematics to perform maintenance on ALSATOM SU MPC are the same for the following models: SU
140/D MPC, SU 140 MPC, SU 100 MPC, SU 50 MPC. In the last two models some components are not
used. Refers to bills of materials of every model on the last page of this manual.
SU 140/BD MPC only has different schematics and bills of materials.

PRELIMINARY
PAY ATTENTION!! BEFORE TO CONNECT THE UNIT TO MAINS, CHECK MAINS VALUE ON REAR
SIDE ELECTRICAL DATA LABEL.
Remove F3 fuse –connected to power supply for HF output –placed on main board (alsa code 801336).
SETTING PROCEDURE
J11 connected to GND is needed to switch ON the unit in setting mode. To do this, a 100 ohms/ ¼ watts
resistors must be used. This avoidsalarms due to setting not yet carried out or in case of troubleshooting.
After the unit is switched on, connection from J11 and GND can be removed, until the next switching on.
With the unit in setting mode, display showsdifferent parameters according to what mode is selected to let to
monitoring the whole unit. Refers to the following table for shown parameters according to the mode selector.
Mode selector Cut display Coagulation display
Pure Cut HF output power setting Proportional signal to HF output power
Blend Cut HF output power setting Proportional signal

Micro Coag Proportional signal to mains HF output power setting
Bipolar Coag Proportional signal to HF output power
HF output power setting
+5V AND +15V LOW POWER SUPPLY CHECK
In setting mode, connect a multimeter in parallel to D28 (“TP1”) on main board. DC voltage must be +5V(±
0.2 V). Next connect multimeter to “TP2” and check DC voltage: this must be +15V(±0.6 V).
D/A CONVERTER VOLTAGE REFERENCE CHECK
Connect multimeter to J8 (“TPA”) on microcontroller board and check if DC voltage is +5V (± 0.01V); set
voltage using R20 pot if required.
PAY ATTENTION!!! CARE SHOULD BE TAKEN TO SET THAT VOLTAGE! IF VOLTAGE REFERENCE
IS HIGHER THAN 5.1 V, MICROCONTROLLER COULD BE DAMAGED. IF SETTING IS REQUIRED,
REMOVE J8 JUMPER, SET REFERENCE VOLTAGE WITHOUT EXCEED THE ABOVE MENTIONED
LIMIT. AFTER PLACE J8 JUMPER IN ITS ORIGINAL POSITION.
SETTING OF NEUTRAL PLATE ALARM CIRCUIT
(not needed in SU 140/BD MPC)
Connect the oscilloscope probe to “TPB” on microcontroller board; set R35 pot to obtain a 71 kHz (±2 kHz)
square waveform.

Check the neutral plate alarm circuit using various resistors: with values higher than 100-200 ohms alarm
occurs. With values lower than 100 ohms the circuit doesn’t give alarm and the unit can be used.
HF OUTPUT POWER FREQUENCY CHECK
Connect the oscilloscopi probe to “TPC” test point on microcontroller board and check a frequency of 938
kHz (±5 kHz); waveform must be like the following:
SETTING OF RAMP DRIVING SIGNAL
Set the unit in CUT mode with power setting at its minimum level, connect the oscilloscope probe to “TPD”
test point; press the footswitch and set R31 pot in order to obtain the following waveform (ramp signal must
be set at 4 V exactly in all models with both monopolar and bipolar output; only in SU 140/BD MPC ramp
signal must be set at 4.120V).
HF OUTPUT MOSFETS DRIVING SIGNAL CHECK
Connect the oscilloscope probe at “TPE” test point.
Set power setting at its maximum level.
Activating the unit in CUT mode,check the following waveform:

To check correct pencil activation mode using a standard pencil. If no activation occurs, turn R75 pot slightly
counter clockwise. Moreover,pushing both pencil buttons at the same time unit must give alarm.
Switch the unit OFF and place F3 fuse in main board.
HF SECTION POWER SUPPLY CHECK
Switch ON the unit in setting mode.
Connect the multimeter to R18 placed on main board; check a +81V (±5 V) DC voltage. This voltage can’t
be set.
SETTING OF MINIMUM AND MAXIMUM HF OUTPUT POWER LEVELS
Set 80 in CUT mode, connect a 500 ohms/200 Watts non-inductive load to monopolar output (in SU 140/BD
MPC load must be 400 ohms).
Start the unit: HF output current flowing in the load must be 400 mAmps (i.e. 80 Watts). In SU 140/BD MPC
current must be 440 mAmps.
If HF output current is different from the above mentioned value, turn R31 pot on microcontroller board.
Set 10 in CUT mode and start the unit.
Turn R39 pot on microcontroller board to obtain a HF output current of 145 mAmps (i.e. 10 Watts).
Since maximum and minimum settings are interactives, above mentioned steps must be performed two or
three times in order to obtain best setting.
SETTING OF I_LEAK SIGNAL
Start the unit in CUT mode setting up values in the following table and check corresponding values on COAG
section display.

RICERCA GUASTI TROUBLESHOOTING
To monitoring the unit, and make easy troubleshooting, the unit software gives different alarm codes
depending on the failure. So it’s possible to look for it directly on the damaged section or ask for information
to our technical dept. giving the appeared error code.
The unit advises about error codes using different acoustic signals: number of acoustic slow repeated gives
what error occurs. Refers to the following table for the complete list of error codes.
N° repeated

13 Error in watchdog timer Microcontroller board
-Neutral plate Main board
-Wrong activation by the user (press cut pedal
with selector mode in bipolar) -
-Wrong activation by the user (press cut and
coagulation pedals at the same time) -
NOTE: last three errors have no alarm code because are recoverable failures.
Neutral plate a red light on panel advises about it; in models with displays, unit
shows PPP on CUT display.
“Cross” activation if a conflict exists from user activation and selector mode position.
The unit advises with blinking yellow and blue lights for CUT and
COAGULATION and a intermittent acoustic signal as well. In
models with displays unit shows EEE on CUT display. To solve this
problem, simply stop the activation.
Simultaneous activation as above, when two pedals or two pencil pushbuttons or a
pushbuttons and a pedal are activated at the same time.
