9 Malfunctions And Errors
The System-Manager is designed for many years of constant use. Nevertheless, there may be faults. It is very often,
however, that the causes for these faults and errors do not occur in the System-Manager itself, but in the peripheral
system components. The following description should be used as a helpful guide to find the sources of malfunctions and
to put the device into operation as soon as possible so that unnecessary costs can be avoided. Certainly not all errors
are listed below. You will find the most common errors and symptoms covering the major part of all possible errors. Send
in the System-Manager only when you are sure that none of the below-described errors has occurred.
The System-Manager is protected against damage by various measures. Nevertheless, always take utmost care in the
proper operation of the System-Manager. Short hints of the malfunctions are indicated with the help of the LCD display.
However, errors are only properly indicated in which the system has been properly installed. If there are other
malfunctions than the ones described below, please check first of all if the System-Manager has been connected to the
battery, the module and the loads correctly in the right polarity. Afterwards, check the safety fuses. In each case of
malfunction, the System-Manager automatically switches off the load.
