Calling up the test programs
When switching on the unit, hold down the CUT effect key. »Pr. 1« appears in the displays on the front
panel.
The required test program number can be selected via the »Up/Down« keys in the COAG field.
The selected test program is started by pressing the CUT effect key.
If not described differently, the individual test programs can be cancelled and exited again by briefly pressing
the CUT effect key.
1 Basic setting of the front panel
Set the front panel as required. (Attention: to switch over the CUT effect, only press the effect key briefly,
since the Save process is started if it is pressed for a longer period of time!)
To save, the CUT effect key must be held down for about 3 seconds. At the same time, the Save process is
indicated symbolically in the display together with an acoustic signal. Once the Save has been completed,
there is a short tone. If the CUT effect key is released too soon, nothing is saved and therefore the previous
setting or the setting preprogrammed at the factory for the front panel is again valid.
Once the Save has been completed, Test program 1 is exited by releasing the CUT effect key.
If Test program 1 is exited without storing a new front panel setting, the unit must be switched off to do this.
2 Calling up the ERROR list
The ICC units are equipped with a system for error detection, error indication and error memory. Every
error is labelled with an error number (ERROR No.). The ICC 50, ICC 80 and ICC BIPOLAR units store
the last 20 ERROR numbers. Test program 2 indicates the stored ERROR numbers. The most recent error
is in Memory location 1.
After activating Test program 2, the display »Er-.—« appears for about 1 second, and then 1. xx, where
»1.« stands for the last error and »xx« is the number of the error described in the error list.
Using the Up/Down keys in the CUT field, the 20 stored errors can be selected. For example, »2.« then
stands for the penultimate error, »3.« stands for one before that, etc.
Press the CUT effect key for 3 seconds to delete the entire error memory. This is indicated acoustically and
symbolically in the displays. The deletion is complete when a short tone is heard. If the CUT effect key is
released too soon, the memory is not deleted.
Then exit the test program.
To exit the test program without deleting the memory only briefly press the CUT effect key.
3 Programming the required activation time limit
Display of »tL.« for time limit and »—«for the required limit value.
Using the Up/ Down keys in the COAG field, the permissible activation time is set in seconds.

This value must be stored in memory by pressing the CUT effect key for about 3 seconds. Refer to Test
program 1.
It is possible to exit the test program without saving a new value to memory by briefly pressing the CUT
effect key.
4 Activation of all visual front panel displays
5 Activation of all acoustic signals
Audible signals are selected using the »Up/Down« buttons in the CUT field (display t.x). By pressing any
button in the COAG field, the alarm volume can be adjusted.
• t.1: Signal for activation CUT
• t.2: Signal for activation FORCED and SOFT
• t.3: Signal for activation BIPOLAR
• t.4: Alarm signal
6 Manual closing of the output relay
Display: r.x xx, in which »r.x« stands for the relay number.
By pressing any button in the COAG field, the two relays can be switched as required, which is indicated by
»on« in the COAG display.
• r.1: Bipolar output
• r.2: Monopolar output with neutral electrode output
• r.r.: Both outputs

10 Measurement of the internal 15 volt supply voltage (»U dd« for Vdd)
11 Automatic checking of the power supply unit for the entire range 0…90 V
Automatic testing is activated with the footswitch for CUT. During the run of the test, indicated symbolically
in the COAG display, the footswitch must remain pressed.
The voltage is increased from 0 to 90 volts and measured internally at the same time. If there is a difference,
this may be displayed as an error (ERROR 80 and 81).
After this run, a voltage of 90 volts is set which can be measured between MP2 and MP1. The measurement
value of the internal measurement is indicated in the COAG display.

12 Adjustment of the phase control for the HF generator
This adjustment is made as the generator idles, but with the monopolar patient lines connected.
After starting up the test program, the power unit voltage is set to 10 volts (Display: U_ 10).
Using the CUT footswitch, the generator is activated. The HF voltage is measured using an oscilloscope
and adjusted to a sinusoidal characteristic at TP3. During activation, the power unit current (I_ xx) is
displayed, which must at the same time be at its minimum.
As soon as the footswitch is released, the power unit voltage is automatically set to 50 volts. The generator
is again activated using the CUT footswitch and set at this higher voltage as described above.
Then the whole process is repeated for a power unit voltage of 90 volts. For the final adjustment, the clean
sinusoidal characteristic has a higher priority than the power unit current, which should nevertheless be
close to its minimum.
By then releasing the CUT footswitch, the test program is automatically exited.
13 Calibration of the HF power output (c.P. hF)
ATTENTION
This test program can only be conducted in the unit's Special Test Mode. To do this, the bridge J7 must be
connected, otherwise the display »J7 n.c.« will appear.
An HF power meter (APM 600) is connected to the monopolar output. CUT is activated with the footswitch
at a load resistance of 500 ohms set at the output. Via the »Up/Down« keys in the CUT field, the output
power is adjusted in such a way that the value measured by the power meter corresponds to the setup value
on the front panel.
Proceed in the same manner at a load resistance of 200 ohms when activating SOFT. Here the power is set
via the »Up/Down« keys in the COAG field to the preset value.
To save the calibration values, the CUT effect key must be held down for approx. 3 seconds until a high
tone is heard which indicates that these have been saved to memory.
14 Automatic calibration of the NE monitoring
ATTENTION
This program can only be conducted in the unit's Special Test Mode. To do this, the bridge J7 must be
connected. Otherwise the display »J7 n.c.« will appear.

At the NE socket a resistance of 260 ohms is connected via a standard NE cable. Then the reference value
for the NE monitoring is automatically adjusted by the unit, which is indicated by the appearance of an
unbroken line (»—«) in the COAG display and the illumination of both the red and the green NE LEDs.
This calibration value must now be stored by holding down the CUT effect key for 3 seconds.
15 Checking the activation signals (accessories) and safety shut off feature
All four activation signals (finger- and footswitch) must be pressed at least once so that instead of »— —«
a display of »oo oo« appears and the test program is automatically finished.
16 Automatic burn-in procedure for 2 hours (»2h b.i.«)
Automatic burn-in procedure for 2 hours (»2h b.i.«) with 25% activation (10 sec ON, 30 sec OFF), in which
the maximum power (50 watts) is output for CUT at 500 ohms.
A 500 ohm load resistance (noninductive and noncapacitive) is connected to the monopolar output.
Before the burn-in procedure can be started, the CUT footswitch signal must be present.
Start the procedure with the CUT effect key.
17 Setting programmable options (»P.O.«)
For example, to lock the activation signals according to Spanish regulations.
ATTENTION
This program can only be conducted in the unit's Special Test Mode. To do this, the bridge J7 must be
connected. Otherwise the display »J7 n.c.« will appear.
The possible options can be called up in the COAG field via the »Up/Down« keys. To save the option
currently displayed, or to switch the unit to this mode, the CUT effect key must be held down for approx. 3
seconds as for all save procedures.
Options:
• St.: Standard
• SP.: Spanish version: if another activation signal is detected during activation, the unit switches off
immediately with an error message.

21 Verification of the modulation timer and the modulation monitor (»t.t.«)
At the test program start, the timer is initialized and switched on. Activation using the CUT footswitch turns
on the generator (with the output relay open) and the feedback is measured. In the COAG display, the
measurement value for the feedback is indicated. This must accept a value of 30 (28–32). Greater deviations
are not permitted.

ERBOTOM ICC 50, ICC 80, ICC BIPOLAR
Automatic error detection, indication and documentation
ERBOTOM ICC series high-frequency surgical units are equipped with a device for automatic error detection,
indication and documentation (ERROR monitor).
Error detection
For ERBOTOM ICC series equipment with software version 1.07, the ERROR monitor can detect up to 91
different errors, depending on the type of equipment and its features, and indicate these on the display.
Error indication
Error numbers (ERROR nos.) are assigned to the various errors. If an error is detected, it is immediately
reported. The error report is both and visual and audible.
Error documentation
The error numbers of detected errors are automatically saved in chronological order. Since only 20 memory
locations are available, only the last 20 error messages are displayed. If the same error is detected several
times in a row, the corresponding error number is then saved only once in consideration of the limited number
of available memory locations. The error numbers documented in memory can be displayed via Test program
2 and deleted.
Troubleshooting for ICC family equipment
The ICC equipment family is equipped with an error detection system which records the last 20 (ICC 50, ICC
80, ICC BIPOLAR) errors in an ERROR list and saves them in memory. This error memory can be called up
via Test program no. 2. The idea of troubleshooting is to help the user of the equipment in the event of
malfunction. He should thus be capable of localizing errors himself and deciding whether this is an operational
error or an error originating with the accessories which he can possibly remedy himself, or whether it is
necessary to contact the technical service.
If there is a complete failure of the system and no display is visible, the power supply may have been interrupted
or the voltage supply inside the unit is defective. In such a case, first check whether the outlet used is live or a
fuse in the house power supply has been tripped (Does a different unit function at this outlet?). If the outlet
used is live, check the powerline to the unit and replace if necessary. The equipment fuses on the rear panel
should also be checked and replaced if necessary.
If these efforts produce no results, there is presumably an error within the unit. You should then contact the
technical service.
In the case of a malfunction with a properly functioning display, but without indication of an ERROR number
on the display, the error may be located in defective accessories. There may, for example, be a defect in the
fingerswitch or footswitch, or there may be a power interruption. The cause of the error may be determined by
exchanging the accessories used.
To determine other causes of errors, an ERROR number in the unit display indicates the course of further
action according to the following table.

2 ERROR list20 / 58

1Activation time limit reached.
If the activation time limit has been set too short, extend this by using Test program no. 3.
2
During monopolar activation, the NE monitor produces an impermissible value.
Check whether the NE is correctly applied and connected to the unit. Check the NE lines.
Tech. Service: Check NE monitor.
3
Activation of the unit without prior acknowledgement of the front panel setting.
Setup values on the front panel must be acknowledged by pressing any key before the unit
can be reactivated.
4Activation of CUT with nonspecified power setting.
With a nonspecified power setting, the CUT function is inactive.
5Activation of COAG with nonspecified power setting.
With a nonspecified power setting, the COAG function is inactive.
6
Activation of COAG with fingerswitch at BIPOLAR setting.
The unit is setup for bipolar coagulation and cannot therefore be activated with the
fingerswitch for coagulation, but rather only with the footswitch or via AUTO START.
