Gasing regulation
The solar controller eliminates or reduces the formation of acid layers by gentle, controlled gassing. The solar controller is suitable for the
charging of lead-acid, AGM and lead-gel batteries as the thresholds are selected in such a way that the recombination of hydrogen within
the closed cells takes place without triggering of the pressure release valve. The gasing regulation is also temperature-dependent. Due to
the integrated temperature sensor the cut-off voltage will be automatically adjusted in accordance with the ambient temperature.
Temperature compensation
The integrated temperature sensor ensures optimum adaptation of the charging voltage to the battery ambient temperature. For this
purpose, the controller and the battery should be operated in the same room.
Changing the internal fuse
The solar controller has an internal plug-in fuse.
For changing the fuse, the housing of the solar controller needs to be opened. For this
purpose, disconnect the connected cables and the four screws on the side of the housing. Now it is easy to remove the lid of the housing
and you have free access to the fuse.
Attention: Replace the fuse only by a fuse of the same type and rated current!
Now close the housing of the solar controller.
Ensure that the temperature sensor and the LEDs are correctly placed in the lid and that no cables are squeezed or damaged.
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, pressing any other keys at the same time is strictly prohibited!
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. In the case of no load operation the battery current will be indicated with 0.1-0.2 A L.
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.
The next menu shows the voltage values occurring:
The value on the left is the maximum occurring battery voltage, which depends on the battery type, internal resistance of the battery,
charging current, temperature and so on. 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/Vista/Win 7 with serial interface. Approx. 4 MB of free hard disc space are required for installation. We recommend a
screen resolution of 1024x768.
Connection to USB- Interface
When connecting the solar controller to a USB interface we suggest the use of an EX-1302 (UBS to 1S RS-232port) converter cable by
Exsys.
Transfer protocol solar controller-PC:
Parameter
Baudrate: 1200
Parity: no
Databits: 8
Stopbits: 1
To retrieve the data the PC must send F<CRLF>
Response of the SCD: In this sequence the data will be returned as ASCII signs.
For testing purposes you can use the HyperTerminal- Program.
R: current voltage; current power; current temperature; minimum voltage; maximum voltage; minimum power; maximum power; CRLF
To delete the minimum/maximum data the PC must send L<CRLF>
The values will be immediately deleted.
