LCD-display (only models with LCD display)
When the solar controller is connected to the battery voltage, an initialization process takes place for approx. 1
second. During this time, the manufacturer's name appears in the display:
When initialization is complete, the display changes to the following:
The value on the left is the battery voltage, the value on the right is the battery current. The letter on the far right
indicates the status: C = charging, D = discharging.
The zero point of the current display is adjusted during initialization. If, over time, the offset values become
larger, press the "Set" key and the "Next" key simultaneously to adjust the zero point of the current display. The
module and load side must be shut down briefly when the zero point is recalibrated, to ensure correct display
indication.
Press the "NEXT“ key to display other measurement values.
The next menu shows the current values occurring:
The value on the left is the maximum charging current occurring. The value on the right is the minimum charging
current occurring. The negative sign indicates discharging.
To delete the min./max. values press the "Set" key and then simultaneously the "Next" key. The current values
are then stored in the min./max. memory.
The next menu shows the voltage values occurring:
The value on the left is the maximum battery voltage occurring. The value on the right is the minimum battery
voltage occurring.
To delete the min./max. values press the "Set" key and then simultaneously the "Next" key. The current values
are then stored in the min./max. memory.
The next menu shows the current temperature:
When the "NEXT“ is pressed again, the display jumps to the original representation.
Serial interface (only for models with LCD display)
The data can be accessed via the serial interface with the aid of a proprietary 9-pin RS232 cable. Please refer
to the "read me" file in the software instructions for details. PC requirements: Pentium as of 100 MHz with at
least 16 MB RAM and operating system Windows 9X/NT/XP/ME/2000 with serial interface. Approx. 4 MB of free
hard disc space are required for installation. We recommend a screen resolution of 1024x768.
Troubleshooting
Reverse polarity of the battery: plug-in fuse melted; replace with the same type and nominal current (see
Changing the internal fuse).
Reverse polarity of the modules: must always be avoided!
Reverse polarity of the consumers: These can be destroyed before the fuse is triggered. Batteries store large
volumes of energy. In the event of a short circuit this energy can be quickly released and cause a fire due to
heat development at the point of the short circuit.
Two LED’s provide information about the status of the system. The current status of the LED’s can, in
conjunction with certain criteria, also indicate a fault in the system.
