If the temperature sensor is short-circuited or damaged, the controller will charge
or discharge at the default temperature setting of 25 ºC
(no temperature
compensation).
3 Wiring
Installation Procedure:
Connect the system in the order of
❶
battery
❷
load
❸
PV array
, and
disconnect the system in reverse order
❸❷❶
.
NOTE: While wiring the controller, disconnect the circuit breaker or fast-
acting fuse. Ensure that the polarity of the electrode is connected correctly.
NOTE: A fast-acting fuse whose current is 1.25 to 2 times the rated current
must be installed on the battery side with a distance from the battery not
longer than 150 mm.
NOTE: The LS-B series is a positive ground controller. Any positive solar,
load, or battery connection shall be earth grounded as required.
NOTE: If an inverter is to be connected to the system, connect the inverter
directly to the battery, not to the load side of the controller.

NOTE:
1) When the battery type is sealed, gel, or flooded, the adjusting range of equalizing
duration is 0 to180 minutes, and boost duration is 10 to180 minutes.
2) The following rules must be observed when modifying the value of the parameter in the
user battery type (factory default value is the same as the sealed type):
A.
Over Voltage Disconnect Voltage > Charging Limit Voltage ≥ Equalize Charging
Voltage ≥ Boost Charging Voltage ≥ Float Charging Voltage > Boost Reconnect
Charging Voltage.
B.
Over Voltage Disconnect Voltage > Over Voltage Reconnect Voltage.
