Nemtek SOL-REG140 User Manual

6. Operation
6.1 Power up
When connecting a battery, some or all (depending on the battery condition) of the
"BATTERY CONDITION" LED's should light up.
The "LOAD DISCONNECT" LED might also light up, but will switch off after a few seconds if
no abnormal condition is present (See section 6.3).
6.2 Battery Charge
When the solar panel is charging the battery by more than 200mA, the green "SOLAR
CHARGE" LED will light up.
The "BATTERY CONDITION" LED's give an indication of the current battery voltage as
follows:
LED's On
Green, Yellow and Red
Yellow, Red
Red
6.3 Load
The load output provides a connection to drive a load of up to 10A at the current battery
voltage. The red "LOAD DISCONNECT" LED will light up and the load automatically
disconnect in the following scenarios:
6.3.1 Undervoltage Protection
When the battery voltage drops below 11.2V the load is disconnected to prevent damage
to the battery. As soon as the battery voltage recovers above 11.6V, the load will be
automatically reconnected and the LED will go off.
6.3.2 Overcurrent Protection
When the load terminals are short circuited or the connected load draws in excess of 10A,
the load will be disconnected. The load will be reconnected and the LED will go off in a
few seconds after the short circuit is removed or the load current falls below 10A.
If a higher load current is required, the load can be connected directly to the battery.
All protection will be bypassed in this case.
