Fault during an internal self-test.
Reset the fault; switch the mains voltage off and on again if necessary.
Using the remote control software, compare the current parameter setting and last
working data record.

Different input signals on main processor and monitoring processor terminal-
H
Fault during an internal self-test.
The digital input signals for the main processor (H) and monitoring processor (Ü)
are compared and are not the same.
Reset the fault; switch the mains voltage off and on again if pertinent.
Check all fuses in the device.
A bouncing signal can lead to different states being detected between the main and
monitoring processors.
In the case of the main and monitoring processors, the detection of the digital input
signals takes place at slightly different times. A signal change is present only long
enough for the main processor to detect it, but not the monitoring processor.
Check the signal sequence.
If fault messages are constantly appearing one after the other
exchange the
device or the respective card (processor card).

H/Ü
Fault during an internal self-test.
Reset the fault; switch the mains voltage off and on again if necessary.
Check all fuses in the device.
If the display remains dark or shows confusing characters, some or all of the LEDs
will light up and faults 111 and 140 will appear.
After the exchange of an EPROM or RAM:
- Remove the processor pc board
Check the components for the correct polarity (all notches point in the same direc-
tion).
Check whether all components are properly inserted (e.g., whether any prongs are
bent), and press them in firmly if necessary.
Check the proper seat of the processor card connection to the backplane.
Check the proper seat of the power supply card connection to the backplane.
If fault messages are constantly appearing one after the other
the EPROM pro-
gramme is possibly defective.
Request a new programme EPROM from LAMTEC with the precise specification of
the respective purchase order number, sales order number, and commission of the
device. Return the defective EPROM in any case (for the address, see the overleaf
of this publication).
