Operating Instructions for Solar Charge Regulator LRM 1218
Leisure battery
Starter battery
4
The starter battery is also charged -- as soon as the leisure battery has finis-
hed the main charging phase.
The solar regulator has an SDTBUS connector and so can be integrated
perfectly into bus systems from Schaudt. For the upgrading of older systems
(such as the DT 201 and DT 220 control panels in conjunction with EBL 101
and EBL 220), a connector with an appropriate analogue signal to display
the solar currents in the leisure and starter batteries is provided.
Two LEDs for "Operation" and "Charge retention" provide information on
function and broadly full battery. The device has a very compact and light-
weight design. The fan fitted is very quiet and runs only when the perfor-
mance is high.
Its function means the MPP LRM 1218 solar regulator is able to deliver (de-
pending on conditions such as outside temperature and level of sunshine) a
5 ... 30% higher solar current than conventional series regulators (a low out-
side temperature and high level of sunshine would be ideal).
Three different charging curves ("Lead-acid", "Lead-Gel/AGM I" and "AGM
II"), or supply with a fixed voltage, can be set from two slide switches.
The charge curve however is dependent not only on the setting of the bat-
tery type switch, but also on the battery temperature determined (when an
optionally available battery temperature sensor is connected or when the
LRM 1218 is connected to an SDTBUS system having a battery temperature
sensor).
The preference is to load the leisure battery. As soon as the LRM 1218 re-
stricts the loading voltage of the leisure battery, it indicates the broad char-
ging of the leisure battery. Charging of the starter battery is activated at this
moment.

Operation

The solar charge regulator has no controls.
The LRM 1218 solar regulator may have to be readjusted when the battery
type is changed:
Battery type set Battery type set
Supply mode
AGM2
Lead-gel / AGM1
Lead-acid
The charge regulator supplies a constant output voltage in supply mode.
Y
The two switches are well recessed to stop them being used incorrectly.
Y
A small screwdriver may have to be used to change the switches.
