4. Hardware evolution of Thermatur 200

Version A:
Initial version.
Starting in all units from SN 10 (01/1992)

Version B:

Modification of tuning capacitor.
Capacitor is divided in 2 parts:

- Fine adjustment capacitor plate

- Coarse adjustment capacitor plate
This will result in a more ‘stable’ tuning during the treatment since the unit can change the capacitor
value in smaller steps.
This modification was introduced together with the release of software version 6.2.
For 230 V units: starting from SN B852 (05/1996)
For 115V units: starting from SN B5047 (05/1996)

Power supply FUBA 702

New, smaller PCB (for more information: chapter 4.1.2)

For 230V: starting from units with SN B1253 (01/1999)
For 115V: starting from units with SN B5101 (04/1999)

Power supply FUBA 702A

Same as FUBA 702, but with adjusting potmeter.

For 230V: starting from units with SN B6058 (12/1999)
For 115V: no information

Version C:
Amplification of SUM/DIFF of A 200 from 1 to 0.82. The generator A 200 remains forwards and
downwards compatible.

For 230V: starting from units with SN C6168 (06/2000)
For 115V: no information

5. Software evolution of Thermatur 200.

V 6.0:
Initial version: from 12/1991 to 09/1992

V 6.1:
Improved keyboard function. From 10/1992 to 04/1996

V6.2:
Together with hardware modification to version B.
Indication of intensity: displays set power and not the real power.
For 230 V units: starting from SN B852 (05/1996)
For 115V units: starting from SN B5047 (05/1996)

V 6.3:
Special version. Indication of peak power (max: 400 watts)
For 230 V units: only for SN 6209 to 6217.

V 6.42:
For units delivered in 2002.

In version 6.2, the error message FE6 showed up in case of strong patient movements during a
treatment. This problem is solved in version V6.42.

In case of a poor tuning (SWR>6), the unit will start searching for a better position of the tuning
capacitor, just like it does when starting a treatment (full turn).
In case of SW V6.2, the unit could hang up (oscillation). This problem is solved in version V6.42.

The range in which the generator starts oscillating is reduced.

6. Operating voltages

Before any repair work shall be done, it is important to check the operating voltages.

6.1 Mains power

When the unit is powered up, both the mains switch and the display will light up. If not check the
mains fuses (F001/F002) and replace with the same type:
230 V: SP 6.3A fast (ceramic pipe)
115 V: FST 6.26A, slow (glass pipe)

6.2 Operating voltages coming from power supply PCB (A 100)

What you need to know:

There are 3 different versions of power supply PCB (all switched PS).

Power supply initial version

: big PCB with adjustment potentiometer. Not compatible with other
versions.
