MM-R/MM-RC Remotes Instruction Sheet
ABSORB LED (yellow)
•
On (solid) – Absorb Charging; the charger is in the Constant Voltage
stage and begins once the bulk voltage has been reached. The DC
charging current starts to taper down to maintain the Bulk voltage
setting. Absorb Charging time is based on the inverter's default AHr size.
•
Blinks On (1 time every 4 seconds) – Charger Back-off (while in Absorb
mode); the charger current is reduced. This occurs if: 1) The internal
temperature is very hot (charger reduces the charge rate to maintain
temperature) or, 2) The AC input voltage has fallen below 85 VAC (charger
reduces the charge rate to help stabilize the incoming AC voltage).
•
Off – the charger is not in Absorption Charge mode.
FLOAT LED (green)
•
On (solid) – Float Charging; at the end of the Absorb Charging time,
the charger reduces the charge voltage to maintain the batteries at the
fl oat voltage (13.5 VDC)—see Table 1-1.
•
Blinks On (1 time every 4 seconds) – Charger Back-off (while in Float
mode); charger current is reduced. Occurs if: 1) The internal temperature
is very hot (charger reduces the charge rate to maintain temperature)
or, 2) The AC input voltage has fallen below 85 VAC (charger reduces
the 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, the charger turns off and goes to Full Charge mode.
If the battery voltage drops to 12.7 VDC, the charger automatically
initiates another fl oat charge.
•
Off – the charger is not in Float Charge mode.
Factory Default Settings
When connected to an inverter, the remote's settings override the default
settings (see Table 1) in the inverter. The settings in the remote are saved
in the remote's non-volatile memory, and will be used—even if DC power to
the inverter is lost—as long as the remote is connected.

* Typically MM/MMS models = 200 AHrs (60 min.) and ME/MS models= 600
AHrs (120 min.).
** These voltage settings are based on the BTS being disconnected; if the
BTS is connected, these voltage settings will increase or decrease depending
on temperature around the BTS—this ensures correct charging.
