Install Battery #1 Temperature Sensor
The optional Battery Temperature Sensor (MC-TS-B) allows your Max Charge MC-614 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 discontinuing charging. 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
When an electric tachometer is used, the alternator’s stator output will provide the electrical pulse needed to drive the
tachometer. The MC-614 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-614, the regulator will ensure that the tachometer will not discontinue supplying
field current when the batteries are fully charged. When connecting the tachometer to the alternator stator output, it will be
necessary to determine the number of poles in the alternator in order to properly adjust
your tachometer. Most Balmar alternators feature 12-pole rotors and stators, though, in
some cases, the pole count may be 14. See alternator manual for specifics. See your
tachometer manual for adjustment instructions.
Install Battery #2 Temperature Sensor
Your Max Charge MC-614 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 and RX circuits provide a connection point with outside monitoring equipment. At this time, the Data TX and RX circuits
are only for factory use.
Install Aux. 1 Lamp
The Max Charge MC-614 regulator’s Aux. #1 (#16) terminal provides the ability to use a visual indicator when the regulator is
operating under the following conditions: Full field (the alternator is working at full power) and Small Engine Mode (the regulator
is being controlled at 50% field output). When a described condition is detected, the regulator sends the Aux. #1 terminal from
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.
