C. LEDs CHECKING ON THE BATTERY CHARGER BOARD
1. GREEN LEDS ARE ON BUT LED DS1 IS
OFF
Check that 24 V are present in J2-1 of Battery Charger Board.
• If it is OK, replace Battery Charger Board.
• If it is not OK, check 24V in J2-7 Line Monitor .
G If it is OK, repair links between J2-1 of Battery Charger Board & J2-7 of Line Monitor Board.
G If it is not OK, check 20 VAC between J2-5 and J2-6 at Line Monitor Board.
-- If it is OK, replace Line Monitor Board.
-- If it is not OK, check voltage from 2T1 Battery Charger T ransformer to the Line Monitor
Board and replace it if necessary.
2. SOME GREEN LEDS ARE NOT ON AND DS1 IS
ON.
Check Fuses F7 to F21(2A, 250 VAC) (Charger Sectors) of the Battery Charger Board.
Check V AC at J6 and J4 in Battery Charger Board (connectors J6 and J4 must be plugged in the
Board), it should be 28 VAC (measure between: J6-1 & J6-2, J6-3 & J6-4........... until J6-15 & J6-16,
and also check J4-1 & J4-2 ........ until J4-13 & J4-14).
• If VAC is OK, replace Battery Charger Board.
• If VAC is not OK, unpplug connectors J6 and J4 from the Battery Charger Board and repeat the
measure checking V AC from 2T1 Battery Charger Transformer at connectors J6 and J4, it
should be 28 VAC (measure between: J6-1 & J6-2, J6-3 & J6-4........... until J6-15 & J6-16, and
also check J4-1 & J4-2 ........ until J4-13 & J4-14). Check 2T1 Battery Charger Transformer and
replace it if necessary .
3. NONE LED IS
ON
Check that Generator is Powered ON.
If DL1 is blinking (yellow) at Line Monitor Board and DL2 and DL3 are OFF
:
• Check VAC between J2-1 and J2-3 at Line Monitor Board.
G If no VAC found, replace Line Monitor Board.
G If VAC found, check VAC in 2T1 Battery Charger Transformer.
-- If no VAC found, check and fix connection at 2T1 Battery Charger Transformer.
-- If VAC found, check 2T1 Battery Charger Transformer.
If DL1 is blinking (yellow) at Line Monitor Board while DL2 and DL3 are ON (any of them)
:
• Check Line VAC +/- 15%.
G If Line VAC is not OK, it is an external problem.
G If Line VAC is OK, review the Line Monitor Board adjustment.
Line Monitor Board Adjustment: Configure SW1 at Line Monitor Board according to
Power Line Voltage (refer to Installation chapter in Service Manual). Measure the Power
Line Voltage with a Digitalmeter and adjust VDC in TP2 with POT1 at Line Monitor Board
as per the following formula:
V
measured
V
nominal
× 2.5 = V
TP2
V
(measured:220V)
V
(nominal:230V)
× 2.5 = V
TP2
(2.4VDC)Example:
V measured is the real voltage obtained with polymeter.
V nominal is the SW1 configuration Voltage.
If all Leds are off at Line Monitor
Board:
• Check VAC in J2-1 / J2-2 at Line Monitor Board.
G If VAC is OK, review configuration of Jumper SW1.
G If VAC is not OK, check (Magnetothermic ) 1SW1 is ON and external VAC power.
