139 0 0 Integr. Flame Detector: selftest fault
H/Ü Especially in the case of oil flames: Reduce the intensity of the flame sensor.
Check the hardware and software configuration:
If the hardware jumper is set to external flame monitoring and parameter 2 is set to
integrated flame monitoring, fault 139 appears as soon as the digital input of the
external flame monitoring becomes active. If the flame signal is detected via the
flame sensor of the integrated flame monitoring in this configuration, the display of
the digital input cycles and a flame fault appears.
140 0 0 The EEPROM is defective.
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.
The EEPROM of the respective processors contains important operating data, the
parameters, and the curves.
During an attempt to save the curve to the EEPROM, a fault was discovered.
Repeat the programming.
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.
Reset the fault if it is still present; the EEPROM is possibly defective.
Request a new EEPROM from LAMTEC with the precise specification of the
respective purchase order number, sales order number, and commission of the
device.
Return the defective EEPROM in any case (for the address, see the overleaf of this
publication).
Exchange the EEPROM, import the current data record into the device using the
remote control software, and check the data record.
When exchanging this component, a basic setting must exist before you can con-
tinue to work with the device.
If you have saved the data of the device using the remote control software, it suf-
fices to reimport this saved data into the new EEPROM.
For more details, see the "Protected data record" description in the remote control
software.
If this is not possible, you must order a preprogrammed EEPROM from LAMTEC.
When ordering, you must enter the device number and software checksums. Only
in this way are mix-ups excluded. For the address, see the overleaf of this publica-
tion.
