When setting the parameters via the LMS14… PC software, the unit runs to a special
programming position. Before changed parameter are stored in EEPROM, the
respective backup values (CRC, test values of the transmission programs, plausibility of
parameters) – if available – and the permitted value range are checked.
Note!
If parameter settings at the heating engineer level (or higher) are changed, the
LMS14… must be restarted, especially when making changes to the Configuration
menu.
Warning!
The OEM must check to ensure the parameter settings (values, access levels,
etc.) of the LMS14... fully satisfy the requirements of the respective application
and make certain that the application conforms to the relevant directives and
standards. If not observed, there is a risk of malfunction or non-compliance
with the directives and standards.
LED flame is lit when the unit detects a flame.
If no flame is detected, LED flame is off or flashes at 1 Hz if errors with the following
error codes occur:
- 118 (water pressure below critical value at H1)
- 177 (water pressure below critical value at H2 [EM1/EM2/EM3]
- 323 (water pressure below critical value at H3)
Note!
If one of these errors occurs, the fuel valve is shut down.
For connection of the external LED, refer to chapter Assignment of terminal X30.
LED alarm is lit when the unit detects an error with a response other than the lockout
position (e.g. water pressure below critical value).
It flashes at 1 Hz if the detected error leads to lockout.
For connection of the external LED, refer to chapter Assignment of terminal X30.
After power ON or a reset, LED flame and LED alarm are lit for a moment.
