High temperature
When temp ≥ 85℃, the controller will enter into the first
protection phase: it will lower the PV input current in order to
lower the temp. There is no alarm on the LCD display.
When temp >90℃, the controller will enter into the second
protection phase: the PV input current will be reduced to zero,
the load output will be switched off and a high temp alarm icon
will show on the LCD.
After the temp has decreased to less than 82℃, BlueSolar PWM
Charge Controller will resume normal operation.
Low battery voltage
When the battery is discharged to less than the Low Voltage
Disconnect (LVD) voltage, the controller will disable the load
output. After over-discharge the load output will be re-enabled
when the battery voltage reaches the Low Voltage Reconnect
(LVR) level.
Over-current protection.
A load output over-current or short-circuit is indicated by a
flashing load icon. The controller will disable the load output and
try to re-enable after 30 seconds.
Shut down after 60s in case of 110%-130% load.
Shut down after 5s in case of 130%-160% load.
Short-circuit protection
The BlueSolar PWM Charge Controller will switch off the load
output and wait for 30s and then try to restart. User should
check and remove the trouble in time.
