Temperature Functions - Blue Sea Systems M2 Instructions Manual

TEMPERATURE FUNCTIONS

(1841)
Monitor up to four temperatures. Provides High/Low level alarms for each channel.
Memory
All M2 meters store settings in flash memory that will remember your settings while powered off.
Meter Power Supply Connections
All meters must have pins 1 (DC Negative) and 2 (DC Supply) connected. These pins are used to provide power to the meter. Connect pin 1 to ground
and pin 2 to a 12V to 48V power source through a 5A fuse.
Temperature Connections
Use Blue Sea Systems Temperature Sensor 1820 or 1821
Only use Blue Sea Systems temperature sensor 1820 or 1821. Other temperature sensors may not give the correct temperature result.
The negative lead of all the temperature sensors should terminate as close as possible to pin 1. For a simple and clean installation, use
Blue Sea Systems PN 2304 as a small common bus bar for all of the meters DC negative connection. There should be one connection between pin 1
of the meter and the bus bar using 18 AWG wire. This connection should be as short as possible to minimize temperature reading errors.
