Functionality Device Error:
From D-IBM2900 Gen3 on, the device are equipped with an error output in form of a
potential-free contact (NO/NC relays contact in the device). This can be used to implement
an error evaluation via an external system (e.g. PLC).
When all accumulators have reached the minimum voltage of approx. 58V, the NO contact
is closed. The relay is always supplied with voltage as soon as all accumulator modules are
in a functional state and charged. It will not open again until one of the battery voltages
drops below 51V, the battery is defective, or the cell temperature has risen above 70°C.
The fault activation occurs immediately (without any time delay) and is independent of the
supply situation of the device. Thus, even before the power supply to the DBL is
interrupted, the fault is detected and can be rectified.
The intelligent charging technology attempts to charge a defective battery, which no longer
has any internal voltage, up to 12 times with interruptions for approx. 10 sec. After that, no
further charging attempt is made. This causes the error signal to be interrupted up to 12
times during this time, but then to be evaluated continuously. After an overtemperature
error, which does not occur during normal operation, the D-IBM must therefore be
disconnected from the mains for 30 sec. Disconnected from the mains. After that it goes
back to normal operation. A device with a defective battery module shows the behavior
after the mains connection that it clears the error 12 times for approx. 10 seconds, but then
remains continuously on fault.
