ECB warnings
Led1
Power supply to electronic circuit is ok (from either the
panel
or the battery).
By removing either the panel wire or the battery wire it is
possible to verify from where the power is being supplied.
Led 2
This is the LED which is the closest to the dip switches. It
indicates how things are working.
1 flash: power supplied from the panel is too low to
charge,
but not low enough to allow product to “light up”
2 flashes: battery charging and searching for MPPT
3 flashes: LEDs on, in other words, light hitting panel is
low
that LEDs are instructed to switch on.
If the battery has insufficient charge to switch to light up
the product, the ECB remains in this operating mode up
until the
end of the pre-set light-up time (which can be set up via
dip switch).
4 flashes: LEDs off as per settings
Continous flashing: Diagnostic mode
Led 3
Placed in the middle of the ECB, this gives additional
input for diagnostics.
1 flash: LED diagnostic mode, with LEDs off, use the
button to switch them on.
2 flashes: Motor diagnostic mode
3 flashes: LED diagnostic mode, with LEDs on and power
supply below the maximum.
6 flashes: LED diagnostic mode, with LEDs on and power
supply above 80%.
Led2
and
Led3
on at the same time means the ECB is
resetting (has a 2 second duration). The ECB is in this
mode when it either switches the LEDs on or if you hold
both buttons down for 2 seconds.
