Float Voltage
You can set
Float Voltage (VFlt at 25°C). When battery voltage is equal to charge
voltage (Vch) for Tabsorption time, WRM15 enter in float state, where battery voltage is
set to VFlt. Float Voltage is temperature compensate (
-24mV/°C at 12V and -48mV/°C at 24V
).

Absorption time
You can set
Absorption time in hours. When battery voltage is in Vch livel for
Absorption time, the WMarine10 start float state, where battery voltage is set to VFlt.

Error codes
With the intervention of del WMarine10 internal protections, there are the below reported error codes.
Table of Error code
When
low battery
symbol is flashing
this indicates that there is the low
battery protection - load has been
disconnected to preserve battery life.
This protection intervenes when the
battery voltage goes under V
LB
threshold that can be set by the user
(fig. 4). WMarine10 leaves this
protection when the battery will be
charged by the PV module at V
OUT-LB
voltage (settable).
Overload protection occurred. The load
current exceeded the maximum allowed limit
for WMarine10 (
Iload
in the “Table of
electrical features”) and the device detached
the load to prevent internal damages. If
there is such a signalling, it is necessary to
check if the current absorbed by the load is <
than the allowed limit. After 1 minute
WMarine10 tries to power supply again the
load. It exits from this condition if the cause
that generated the overload has been
eliminated.
The battery was connected with
inverted
polarities.
Check
the
electrical connections of the battery.
You have this error when the battery voltage
is < than 9.0V. In these conditions, the charge
is disabled.
You have this error when internal
temperature of WMarine10 exceeds
80°C and deactivates the charge. You
exit automatically from this protection
when the internal temperature goes
below the threshold of 50°C (note: the
internal temperature of the charge
controller is not displayed on the LCD).
If you see often this protection we
advise to place the device in a cooler
place.
