Data logger
An SD card enables you to save all the measurement data collected
by the controller over a long period of time. The data logger enables
detailed system control e.g. chronological sequence of yields. In addi-
tion, you can use the stored measurements to optimise the settings of
the solar energy system and thus achieve the highest possible efficiency
of the system.
9.1
Handling the SD card
All standard SD cards can be used, including GB. The SD cards must
be formatted with the FAT16 format and there should be no existing
data on the SD card.
To insert an SD card in your controller, push the SD card, with the con-
tact surface at the front, into the side slot of the controller until the
card engages.
To remove the card press it slightly inwards until it is released and
pushed out by spring-action. The card can now be taken out.
Before you take the card out make sure that the data logger function
is switched off (see chapter 7.3.17). This will prevent any possible loss
of data.
NOTE
SD cards are very sensitive. Ensure that you do not soil the contacts
and that no pressure is applied to the card. Observe the instructions
of the card manufacturer.
The controller manufacturer accepts no responsibility for claims for
damages resulting from defective or lost data.

Display screen
The controller can recognise the different statuses of the SD card:
An hourglass symbol shows that the controller is accessing the SD card
and calculating the remaining days. During this time keypad entries
are not possible and the display is not updated. During this time the
outputs remain at the status they were before the controller accessed
the SD card.
The hourglass symbol is displayed after the following actions:
•
Inserting an SD card
•
Changing the interval time for data collection
•
Changing the date
•
Switching on the controller
•
Resetting the operating switch from "OFF" to "Automatic" after
formatting
•
Switching on the data logger function
•
Changing the clock from 3:59 to 00:00
If an SD card is inserted in the controller, the "Data logger" function is
activated and no SD card error has occurred, a window appears in the
status display in which the data transfer from the controller to the SD
card is displayed. This is illustrated by an animation. A help window can
