ALARM AND SENSOR INSTALLATION

Alternator Temperature Sensor (MC-TS-A) - Optional

The Alternator Temperature Sensor enables the regulator to sense when the alternator tem-

perature exceeds safe working limits. The MC-612 responds by reducing the field current at

the alternator and activating the alarm output. To install the Alternator Temperature Sensor:

Attach the positive and negative wires to the Alternator Temperature Sensor terminals on the MC-

612 (See Figure 4). Observe proper polarity at the terminals.

Attach the heavy lug terminal to a location described below on your alternator. Flat washers are

included with the temperature sensors to ensure solid mounting connections. The following are

typical installation locations:

MID CASE MOUNT - Small Case Alternator - Remove (1) of (4) 5/32" Allen bolts, install probe, re-

secure bolt. (See Figure 5.)

MID CASE MOUNT - Large Case Alternator - Remove (1) of (4) 3/16" Allen bolts, install probe, re-

secure bolt.

Caution: The alternator temperature sensor is not

meant to be used as a method to maintain alternator

temperature. Optional temperature sensors are not a

guarantee of protection against damage from over-

heat conditions. Inspect your system as quickly as

possible if the sensor alarm is activated. Have your

system inspected if overheating occurs.

Battery Temperature Sensor (MC-TS-B) - Optional

When equipped with the optional Battery Temperature

Sensor, the MC-612 will automatically compensate for

variation above and below normal ambient tempera-

tures. The MC-612 is equipped with dual battery sen-

sors to enable sensing at two separate batteries. To

ensure proper operation, be sure the battery terminals

are completely clean and free of corrosion prior to

installation. To install the Battery Temperature Sensor:

Secure the 3/8" copper probe to a clean negative (-) battery terminal (see

Figure 6). The 20' leads may be shortened or extended, if needed. Note: An improperly

installed or corroded battery terminal may generate heat and severely diminish charging

and impede accurate temperature sensing.

While observing polarity, connect the battery temperature pins to the positive and nega-

tive terminals as shown on Figure 4.

Note: Battery #1 terminal is capable of temperature compensation and activating

warning alarm. Battery #2 terminal activates the warning alarm only. The upper volt-

age limit for battery compensation is 14.8 volts. If higher voltage limits are desired,

adjust voltage levels in the Compensation Limit (CL) mode of the advanced program-

ming adjustments.

Lamp / Alarm Outputs

The MC-612 includes two output terminals, one for system alarms (dash lamp) and and another for advisory information (Aux.

#1). These terminals output battery negative (0.5-amp max) when in alarm condition. Refer to Figure 7 for common system con-

ditions that may initiate an alarm. When in the alarm mode, the 3-digit numeric display will indicate the exact cause for the alarm.

Specific advisory codes are shown in Figure 17 on Page 6.

Small Engine Mode

The MC-612 can be modified for provide a half-power setting by installing a toggle switch between the positive and negative ter-

minals of the alternator temperature sensor circuit. When activated by closing the switch, the regulator reduces the alternator

output by approximately 50%. This mode is ideal for smaller engines that are not capable of providing suitable horsepower to drive

both the alternator and propeller at full output. When in Small Engine Mode, the regulator will send a signal to the Auxiliary #1

Status Output.

V. SHORT DISPLAY

The Model MC-612 provides a wide range of operational, programming and diagnostic data through its 3-digit numeric LED read-

out. After an initial start-up period, the numeric LED will cycle through the Short Display, shown in Figure 8 on the following page.

The short display includes manufacturer, model, battery type, charging cycle, actual voltage and target voltage. This display cycles

continuously during regulator operation.
