CAUTION: Reversing the polarity of the terminal connections on any of the alternator or battery
temperature sensors can result in invalid sensing and potential damage to alternators, regulator and/or
batteries.
INSTALL BATTERY #1 TEMPERATURE SENSOR
The optional Battery Temperature Sensor (MC-TS-B) allows your Max Charge MC-620 voltage regulator to monitor your battery
bank for changes in battery temperature, adjust charging voltages to compensate for battery temperature, and respond to a
battery over-temperature condition by stopping charging. For the LiFePO4 profile only, the regulator will also disable charging if
the sensor temp drops to or below 32°F, 0°C. The MC-TS-B sensor includes a 20’ cable, a sensing attachment, lug and positive
and negative regulator plug-in connectors. To install the MC-TS-B:
1.
Connect the sensor lug to the battery negative post closest to the center of the
battery bank. Extend sensor cable to the regulator.
2.
Connect the temperature sensor to the Bat. #1 Temp. terminals on the regulator. It is
essential that the terminals
are connected to the correct pin. Connect the RED wire
to the positive terminal (#8) and the BLACK wire to the negative terminal (#7).
INSTALL WHITE STATOR-IN AND TACH-OUT WIRES
NOTE: Do not attempt to use the White Stator Out to drive a tachometer
unless you have verified that it can be safely driven from a 48V alternator
output. Consult the Tachometer Manufacturer if you are unsure.
When an electric tachometer is used, the alternator’s stator output will provide the electrical pulse needed to drive the
tachometer. The MC-620 has been designed to provide regulated tach output when the WHITE stator wire is connected to the
regulator’s Stator In (#12) terminal and the out feed wire to the electric tachometer is connected to the Tach Out terminal (#13)
terminal. *Not required for magnetic pick-up Tachs.
Stator output can also be used to detect alternator failure. See Page 10 for details.
When the tachometer is connected via the MC-620, the regulator will ensure that the tachometer will continue to operate by
supplying just enough field current to keep the tachometer operating. See your tachometer manual for adjustment instructions.
INSTALL BATTERY #2 TEMPERATURE SENSOR
Your Max Charge MC-620 voltage regulator can accommodate a secondary battery temperature sensor. Used in conjunction
with an optional MC-TS- B battery temperature sensor, the regulator can monitor temperature at a secondary battery bank and
respond to a battery over-temperature condition by discontinuing charging.
To install a secondary battery temperature sensor:
1.
Connect the temperature sensor to the secondary battery bank following the directions provided for the primary battery
temperature sensor.
2.
Connect the temperature sensor to the Bat. #2 Temp. terminals on the regulator. It is essential that the terminals
are
connected to the correct pin. Connect the RED wire to the positive terminal (#15) and the BLACK wire to the negative
terminal (#14).
DATA TX AND DATA RX
Data TX((#10) and RX(#11) circuits provide a connection point with outside monitoring equipment. At this time, the Data TX and
RX circuits
are only for factory use.
