Internal errors
Internal error – the electrosurgical unit does work properly. For safety reasons the functions of the unit cannot be activated. Please contact the authorised EMED service.
Error code |
Description of the error |
It is applies to the outputs responsible for the settings of relays. It is checked whether after a certain state has been generated at a processor port the
501desirable state has really been achieved at its legs.
It may be caused by a breakdown of the ULN2003 system which is connected to the processor outputs.
When the unit is started the voltage is read out at measurement pins in the state of no activation. All the measured results are treated as zero points and if voltage levels are higher than those acceptable in this state, an error is
502reported.
The acceptable voltage is the voltage corresponding to 7 units of a 8-bit converter with 5V reference voltage, i.e. 137mV as a maximum. It may be caused by failure to connect or incorrect connection of the MPM module.
The error of voltage, current or power output measurements.
The voltage, current or power output levels are continuously controlled during
503activation and at all times it is checked whether the obtained results make sense (e.g. it is an error when the voltage and current are almost zero, whereas the power is very high). If the measured results do not make sense and the situation repeats in successive measurements, an error is reported.
