4 General and application
This document describes the connection of Schaudt products developed for
solar systems:
FLRM 1218 solar regulator*
FLR 1218 solar regulator
FLT 320 control and display panel
* the solar regulator LRM 1218 was delivered with two different housing ty-
pes. The connection is the same for both types.
Which devices are to be fitted new and the situation inside the vehicle must
be known before work is commenced. Then the corresponding connection
diagram must be determined and the connectors established in the form
shown therein:

7.1 LR 1218 with LT 320
YWhen the LR 1218 is used on bus systems, display of the solar power
from the main control and display panel is NOT possible, even if it sup-
ports a solar power display. The display on the main panel can only be
activated from the SDTBUS. This is only possible using the LRM 1218
solar regulator.
Set 9990219 (LR 1218 with connector material) is required.

Y*In this case, the solar power is displayed on a suitably configured main
control and display panel (e.g. LT 13 or DT 713) and on the DT 320. The
display on the DT 320 however is also possible when the system is shut
down or the 12 V supply is switched off. This means battery charging can
also be checked whilst the vehicle is idle (such as in winter).
