Diagnostic system by blinking “SUPPLY/DIAGNO”
led
If the battery charger stops before the end of charging
for any reason it is signalled by a number of blinks
(continuously repeated with a pause between one
group and the next) that lets the operator know the
reason for the block.
The set anomaly codes are the following:
Diagnosis led on
: normal conditions, indicates mains
power present.
Diagnosis led off
: mains power absent, new cycle
ready to start.
2 blinks:
battery voltage too high (both when turned
on and during the charging phase).
The limit is set to 2,85 V/el.
3 blinks
: battery voltage too low when turned on.
Comment as above.
The limit is set to 1,4 V/el.
4 blinks:
maximum charging time expired without the
battery voltage rising (14 hours).
“Test” Mode
“TEST” mode can be selected to perform an
accelerated test cycle - 1 normal hour becomes 1
second – and reflects the true voltage limit set. This
mode is activated creating a transition (opening or
closing) of BRIDGE 1 ("TST") during the time when all
the leds are on (the first two seconds after turning on).
In reality, the TEST mode is performed with the same
sequence as the normal mode, with the same limits.
No mains power
As soon as mains power is disconnected, the board
opens all the relays and the “SUPPLY” and “BATERY
CHARGED” leds turn off. It remains in standby in
power savings mode (<10mA) waiting for a new
charging cycle that will start the next time mains power
is connected. The “BATTERY CONNECTED” led that
is directly connected to the battery stays on.
“Fail” Relay
Normally idle, it is enticed only if charging terminates
anomaly. It is release as soon as the mains power is
disconnected.
“Mains” Relay
Enticed while mains power is present, release when
disconnected.
