ADDITIONAL REGULATOR FEATURES
SMALL ENGINE MODE
In situations where additional power is needed for propulsion, the MC-620 provides the option to manually
reduce regulator field output by approximately one half. This option, called Small Engine Mode, can be
accessed by shorting the positive and negative Alternator #1 Temperature Sensor terminals. This can be
done by splicing into the positive and negative wires of the Alternator Temperature Sensor cable (MC-TS-A)
with a switched wire. With the switch in the OFF position, the Alternator #1 Temperature Sensor will work
normally. With the switch in the ON position, the regulator will reduce field output by approximately 50%.
To enable the Small Engine Mode:
1.
If the Alternator Temperature Sensor cable is being used, replace the female terminal connectors on
the cable with Multi-Stack Connectors (Ancor Part # 230612).
2.
Install a standard ON/OFF switch in a location that’s easily reached from the helm.
3.
Run wires from the switch back to the positive and negative terminals of the Alternator #1 Temperature Sensor
terminals
( #5 and #6).
4.
Add appropriate connectors to the switched wires and connect to the positive and negative terminal connections.
DASH LAMP
The MC-620 provides a Dash Lamp circuit that’s capable of providing a signal to a user supplied and installed audible or
visual
alert if the following issues were to occur while the regulator is in operation:
•
Low Battery Voltage <51.2V Adjustable with “ALL.” (See Page 12)
•
High Battery Voltage >62V Adjustable with “AHL.” (See Page 11)
•
High Alternator Temperature 225°F Adjustable with “AL1.” (See Page 12 Requires installation of MC-TS-A sensor)
•
High Battery Temperature >125°F Adjustable with “B1L.” (See Page 12 Requires installation of MC-TS-B sensor)
•
Low Battery Temperature <32° F (LiFePO
4
only) not adjustable.
•
Alternator Failure (No voltage on stator if bdL is enabled)
•
Regulator Overtemp Fixed 194°F
AUX #1 LAMP
The MC-620 provides an Auxiliary Lamp circuit that’s capable of providing a signal to a user supplied and installed audible
or
visual alert to indicate the following while the regulator is in operation:
•
Small Engine Mode is activated
•
Regulator is at full field
