Fig. 1 Battery setting switches and LEDs
T wo LEDs show the current status of the regulator:
F Yellow LED: Device in charge mode (leisure and/or starter battery)
F Green LED: Charge retention active (leisure battery full)
F The two LEDs flash alternately: Supply mode
The solar currents are displayed on a control panel connected (such as an
LT 320) -- refer to the separate operating instructions.
Proceed as follows if a battery temperature sensor is to be retrofitted:
" Switch off the system from the main switch (control panel)
" Remove the ”Solar modules” connector on the LRM 1218
" Remove the ”Leisure and starter battery” connectors on the LRM 1218
" Plug the battery temperature sensor into the LRM 1218
" Plug the ”Leisure and starter battery” connectors into the LRM 1218
F The LRM 1218 solar regulator reconfigures itself automatically -- chan-
ged battery charge curves are now used.
" Plug the ”Solar modules” connector into the LRM 1218
Y A battery temperature sensor connected directly to the solar regulator
has the benefit that charging is temperature-controlled even when the
bus is not active (such as when not in use in the winter break).
4Faults
Please contact our customer service team if you cannot rectify the fault
using the following table.
If this is not possible, such as when you are abroad, the solar regulator can
continue to be used. For faults E271 and E272 (display of only SDT ... bus
systems possible), standard curves are used for charging. Charging is then
no longer temperature-controller .
