Caution: The contacts carry high capacitive loads even after
disconnecting the transducer connection cable. These must be
unloaded by short-circuiting them before measuring and
touching them.
How to proceed:
1. switch off the generator
2. loosen the HF connection cable from the generator (back of
the unit)
3. short-circuit HF pole and mass at the HF plug of the cable;
this unloads the transducer
4. use the ohmmeter to measure the resistance between HF
pole and mass
The measured value should be infinitely high and be at least in
the mega-ohm range. Otherwise, there is a fault.
12 Malfunction of the generator Troubleshooting
12.1 (MF2000
– MF 4000 only)
Generator without SPS control
Normal operation of the generator is indicated by 2, 3 or 4
green lamps in the display (small LED G1
– G4), depending on
the type of generator (MF 2000, 3000, 4000).
If one module of the generator is faulty, the GREEN lamp turns
RED.
The generator is shut down completely, the remaining lamps
(indicating the functioning modules) go out. In order to operate
the generator with the remaining modules, the faulty module/s
must be switched off.
1. Switch on the generator/keep the generator switched on,
turn the frequency switch to „0“ (centre).
2. Use a small screw driver to turn the switch above the RED
lamp (or the lamp that had been RED) from 11 o'clock to 12
o'clock. The RED lamp goes out, the green lamps indicating
the remaining functioning modules go on again.
3. Switch off the generator using the timer and switch it on
again after 5 seconds. The green lamps for the remaining
modules go on. The lamp indicating the switched-off module
remains out. The generator can now be operated with the
remaining functioning modules.
