6.8.4.2 Procedure for parameter
update
The information below explains how to work
with the "Update_function" parameter (see
parameter row 26 in the table above).
The update function makes it possible to
overwrite parameter settings with a parame-
ter set which is saved on an external USB
stick. As a result, the operator can make a
change without having to change the param-
eters by themselves. The modified parameter
set can be provided by HygroMatik.
The procedure is as follows:
»
With the unit switched on, insert the
USB stick into the socket on the
mainboard.
»
Call up the "Update function" in the
services submenu.
The status of the update process is displayed
(see table). Its successful completion is indi-
cated by the "Update successful" status mes-
sage.
»
Switch the unit off and on again. The
parameter set which has been
loaded is activated.
»
To reload the parameter set at a
later date if required (e.g. after a fac-
tory reset), the "ImportDone.txt" file
on your USB stick must be deleted
beforehand. To do so, the USB stick
must be inserted in an external
device (e.g. PC).
If the status "Invalid data" is output after the
update operation, a compatible parameter
set is not available on the USB stick.
The parameter set that is stored on a USB
stick is always linked with a unit serial num-
ber and can only be used for this unit.
6.8.5 History submenu
The fault message history was already
described for the user level in Section 6.6.3.
There are no differences at the operator
level.
