BULK (yellow) -
• On (solid) – Bulk Charging; the charger is delivering maximum
current to the batteries. The charger will remain in Bulk Charge
until 14.6 VDC* is achieved (per Battery Type selection**).
• Blinks On (1 time every 4 seconds) – Charger Back-off; charger
current is reduced. This occurs if: 1. The internal temperature is
very hot (charger reduces charge rate to maintain temperature) or,
2. The AC input voltage has fallen below 85 VAC (charger reduces
charge rate to help stabilize the incoming AC voltage).
• Off – charger is not in Bulk Charge mode.
ABSORB (yellow) -
• On (solid) – Absorb Charging; the charger is in constant voltage
stage and begins after the bulk voltage has been reached. The
DC charging current will start to taper down to maintain the bulk
voltage setting. The absorb charging time is 120 minutes (per
Battery AmpHrs selection**).
• Blinks On (1 time every 4 seconds) – Charger Back-off; charger
current is reduced. This occurs if: 1. The internal temperature is
very hot (charger reduces charge rate to maintain temperature) or,
2. The AC input voltage has fallen below 85 VAC (charger reduces
charge rate to help stabilize the incoming AC voltage).
• Off – charger is not in Absorption Charge mode.
FLOAT (green) -
• On (solid) – Float Charging; at the end of the absorb charging
time, the charger reduces the charge voltage to maintain the
batteries at 13.4* VDC (per Battery Type selection**).
• Blinks On (1 time every 4 seconds) – Charger Back-off; charger
current is reduced. This occurs if: 1. The internal temperature is
very hot (charger reduces charge rate to maintain temperature) or,
2. The AC input voltage has fallen below 85 VAC (charger reduces
charge rate to help stabilize the incoming AC voltage).
• Blinks On (2 times every 4 seconds) – Full Charge; monitors
the battery voltage to determine when to continue charging. After
four hours in the Float Charge mode, charger turns off and goes
to Full Charge mode. If the battery voltage drops to 12.9 VDC, the
charger will automatically initiate another fl oat charge.
• Off – charger is not in Float Charge mode.
* These voltage settings are based on the BTS being disconnected;
if connected, these voltage settings will increase or decrease
depending on temperature around the BTS – this ensures correct
charging.
** These settings are preset by the inverter or the connected
remote (see Table 1, Inverter and Remote Settings), but can be
changed by the ME-RC50 remote.
