Situation
Possible causes and solutions
Digital switching rules do
not work as expected
1. Wrong bank number.
Check and match bank numbers across
connected devices.
2. Incorrect settings or rules.
Check Device settings and active rules
via the YDBMSAVE.TXT file, or with Can Log Viewer (see IX.2).
The Device LED is
continuously giving 1-second
red flashes.
1. Make sure that CALCS is ON.
See CALCS parameter or YD:CALCS
command in Section IX.
2. Make sure your chartplotter supports PGN 127506 «DC
Detailed Status

.
Incorrect SoC readings
1. Battery is not synchronized after a prolonged period
in operation.
2. Battery reconnected after being used separately with
a noticeable loss of charge.
3. (if a new battery is connected) The battery has partially lost
its charge.
In any of the 3 cases, perform a Partial Synchronization (see Section X).
4. NiCd or NiMH battery (see Section III for details).
Device does not recognize
fully charged state when
battery charging is finished
(no LED signals, Partial
Synchronization date is not
updated)
1. Unsuitable settings related to fully charged state.
Revise
and adjust CHARGED_VOL, CHARGED_CUR, and CHARGED_PERIOD
parameters. You may also adjust the CHARGE_EFF value.
This adjustment may require several iterations: if no LED signals appear
after the charging is finished, partially discharge the battery and charge
it again; repeat this step if necessary.
