7.2 Using the SD Card on the main PCB
(M90)
Logging (M90-01)
The SD card supplied as standard can approximately
store one year of logdata. Once the SD card is full,
the oldest data will be overwritten. The main PCB
writes data to the SD card at minute intervals. The
text “SD” then appears on the display. In parameter
M90-01, the status of the SD slot can be read out.

Back-up (M90-02, M90-03)
A week after turning on the unit a back-up of all set
parameters will automatically be stored on the SD
card. This back-up will be replaced automatically
every week. If wanted the set of parameters can be
saved manually from the main PCB on to the SD card
with parameter M90-02. With parameter M90-03 the
set of parameters can be loaded manually from the
SD card on to the main PCB.
7.3 Service parameter
(M99)
In parameter M99 some service details of the unit
can be found.
Parameter M99-01 mentions the current installed
software version of the main PCB.
Parameter M99-03 mentions the amount of hours the
unit has been on power without interruption.
Parameter M99-04 mentions the current installed
software version of the I/O PCB.
Parameter M99-99 is for executing a general reset.
When activating this parameter all parameters will be
restoring to the factory settings. Parameter M99-99
can only be activated by selecting the correct code.
The correct code can be requested at Zehnder.
