Frequency of battery replacement
Typically, the batteries will last for about 6 months of operation. When the
temperature is lower, the energy consumption is higher. Battery life also depends on
their quality.
When the red indicator light flashes in small intervals or the device has stopped
working completely, the batteries should be replaced. It is recommended to avoid the
use of rechargeable batteries as voltage drops may occur during very low ambient
temperatures.
Make sure that the new batteries are not discharged and that they are installed
according to the polarity indicated on their housing and on the battery compartment.
Testing the driver
a) Open the transparent cover of the controller.
b) Adjust the light sensitivity control so that the arrow points to 8 o'clock (on the
imaginary clock face).
c) Disconnect the plug of the battery compartment from the printed circuit board
(PCB)
d) Press the "UP (RST)" button and at the same time connect the plug of the
battery compartment to the printed circuit board (PCB).
e) When the red indicator light is on, the controller will enter the test mode.
f) STEP 1: TEST THE LIGHT SENSOR
