Detailed Wiring
IMPORTANT! The Sensing Description section of this manual gives important details to the location of sensors in the AC and DC electrical systems of the boat. Improper location and configuration of sensors can result in erroneous readings and possible damage to components.
[For 1830, 1833 & 1834 modify quick start drawing to only contain one battery] [On all meters note that pin 4 is only required if the external relay is used or that an external battery is being monitored]Meter Supply Connections
All meters must have pins 1 and 2 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. Note on some DC meters pin 2 is also used to monitor additional voltages.
AC Connections
(1836, 1837, & 1838)AC Current
In most cases, the AC Current Transformer should be located on the main AC line wire before any other devices. See http://bluesea.com/viewresource/86 for more information on AC Current Transformer location.
The Current Transformer does not indicate polarity. The leads should be twisted to reduce the effects of interference from other electrical circuits.
AC Voltage
The AC supply HOT ( Line, or "Ungrounded Conductor") connection should be protected with a fast acting fuse of 0.25A to 0.5A to protect against shorts.
AC connection North American 120/European 230
[Use modified quick start drawings 1838 that shows shore connector w/ breaker and sub-panel assembly]AC connection North American Split Phase 120/240
To monitor a split/phase system, place the AC 1 & 2 Voltage Hot ('LINE", or "Ungrounded Conductors") and Neutral ("Grounded Conductor") connections on the LOAD side of the transfer switch as indicated in the diagram.
Note that AC 1 Voltage Neutral and AC 2 Voltage Neutral are tied together.
[Use modified 1838 Drawing with AC1N and AC2N combined as ACN]For more information regarding Current Transformer placement in 120/240 Volt AC Systems, refer to the following article.
DC Connections (1830, 1832, 1833, and 1834)
DC Current
Some DC Meters (SoC, Ammeter, and Multimeter) require use of a "shunt." Shunts must be connected between the negative terminal on Battery 1 and the main negative bus. All loads and charge sources should have their negative terminals on the main negative bus, with the exception of the M2 negative source which must be connected directly to the battery side of the shunt. Shunt sense wires must be a twisted pair from shunt to the M2 Meter for proper calculation of State of Charge (SoC). Twisted pair wire can be purchased from electrical supply companies, or made by twisting by hand or with an electric drill motor. The current (Amperage) reading for Battery 1 should be negative when it is not being charged and DC power is being used (loads are active). If it is not, reverse the twisted pair DC shunt sense leads.
It is possible to connect the the DC shunt on the positive side of the circuit without a Shunt Shifter (for example on the output side of an alternator) however the measurements will only be accurate to +/- 4%, as opposed to +/-1% on the negative side.
DC Voltage
DC positive(+) voltage supply wires for M2 Meters should be directly connected to the positive battery terminal with a dedicated wire before any other connections. This will ensure correct voltage and SoC monitoring. Use an appropriate in-line fuse (5A suggested) on the positive wire. A twisted pair should be used for V1 (1830, 1833, 1834) and for V2 (1833).
Multiple Battery Connections (1830 & 1834)
[Insert wiring diagrams for 1830 from quick start guide]Single Battery Connection (1830 & 1834)
In this configuration pin 2 and pin 4 must be connected to the Battery positive terminal and pin 1 is connected to ground.
[Insert modified quick start guide with a single battery] Pin 4 is only required if the internal mosfet relay is used.Single Battery Connection (1833)
In this configuration pin 2 and pin 4 must be connected to the Battery positive terminal and pin 1 is connected to ground.
[Insert modified quick start guide with a single battery] Pin 4 is only required if the internal mosfet relay is used.M2 Relay Connections
M2 Meters contains an internal MOSFET relay that can drive external DC loads up to 0.5A. The input is protected with a thermally activated auto-resetting fuse that will protect against shorts. In addition, an inline fuse rated at 5A should be used to protect against shorts. In typical applications, a power source is connected to the Relay+ pin and a load is connected to the Relay Out to Load connection. In the 1830, 1833, and 1834 meters, the Relay+ connection can also be used to monitor a voltage. Pin 4 is only required if the internal mosfet relay is used.
External LED
An external LED such PN 8171 can be connected to the Relay Output terminal. If the system is going to operate at more than 24V nominal, an additional 4K Ohms of resistance should be placed in-line with the LED.
(insert diagram)External Alarm
The Relay+ terminal can support an external audible alarm. Such as the Floyd Bell Turbo Alarm (1070).
(insert diagram)External Relay
If you need to switch more than 0.5 A, you can use an external relay such as 7713 or 7717 Remote Battery Switch. Connect the Relay+ terminal to the red control wire. Activating the internal relay will also activate 7713. NOTE: 9012, 7701, & 7703 Remote Battery Switches are not compatible with the internal relay.

viewfile?j=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUSetting Alarms
The M2 Meter family provides monitoring capability of input channels. The meter can monitor Voltage, Current, State of Charge and Frequency. Alarms are triggered if a channel is above or below a certain user selected threshold value. (Note: not every meter supports every alarm) The following example indicates how to setup an over voltage Alarm.
- Go to the Alarm Setup menu.
- Scroll to the desired input channel (i.e, DC1 Volts Hi).
- Press the Select button and the cursor should start blinking.
- Set the voltage threshold using the ← and → buttons. (Holding down the buttons allows faster selection)
- Press the Enter button to save the change or the Cancel button to cancel any change.
Note: A battery's low voltage threshold cannot be set above its high voltage threshold. Likewise, a high voltage threshold cannot be set below the low voltage threshold. The meter will automatically increase or decrease the voltage thresholds to enforce this.
In the above example, an alarm will set anytime the AC voltage is greater than or equal to 135V.
Voltage Alarm
Voltage alarms can be set for high (Hi) or low (Lo) voltage conditions.
Current Alarm
The current alarm can only be set for over current conditions.
State-of-Charge (SoC) Alarm (PN 1830 Only)
The state-of-charge alarm can only be set if the state of charge is below a certain threshold.
Frequency Alarm
The frequency alarm is only available on AC meters and indicates that the AC frequency is out of range. The alarm is only valid if the input AC voltage is greater than 40 Volts.
Clearing Alarms
When an alarm occurs, the buzzer will sound, the red ALARM LED will light, and the screen will display which alarm was triggered, the Alarm set point and the current value. Pressing any button silences the buzzer and another button press returns to the previous display.
Until the cause of the alarm is resolved, the ALARM LED will remain on and the channel that triggered the alarm (Voltage, Current, State-of-Charge, or Frequency) will blink.
viewfile?j=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUViewing Alarms Status
For any active alarm, the parameter will flash if it is displayed. To view a complete list of active alarms, press Menu>Setup>Alarm Setup. Any active alarm will flash. You may have to scroll through the menu to see all of the alarms.
Relay Setup & Control
M2 Meters provide a set of options for controlling a connected relay. The M2 can trigger the relay based on Voltage, Current, or State-of-Charge or Frequency.
These relay options can be set from the Relay Setup menu. To get there, first navigate to the Setup menu. Then scroll to Relay Setup and press the Select button.
viewfile?j=eyJ0eXAiOiJKV1QiLCJhbGciOiJIURelay Normally On/Off
This setting sets the normal operating state of the connected relay. The options are ON or OFF where ON means the relay is on (contacts closed) in normal operation and OFF means it is normally off (open contacts). Scroll to Relay Normally, press Select(selection will flash), then press the LEFT "←" or Right "→" arrow buttons to change the setting. Press Enter to save your selection. Press Cancel to cancel a change.

Setting Input Thresholds
Settings for each channel's high and low voltage thresholds are provided. The connected relay’s normal operating state will toggle (change state) if these thresholds are met. For both high and low thresholds, the activation and deactivation voltages are different to prevent the relay from rapidly toggling (cycling on and off). Each channel has Hi ON and Hi OFF settings and Lo ON and Lo OFF settings.
Relay with Relay Normally = Off Relay Setup Screen with Relay Normally = Off (Open) viewfile?j=eyJ0eXAiOiJKV1QiLCJhbGciOiJIU Relay Setup Screen with Relay Normall = On (Closed)Example. If the relay is Normally On (closed) and is connected to AC1, then it will open at the User input threshold value for AC1 V Hi Off (135 V). To close again, the voltage must drop below the User's input value for AC1 V Hi On (130 V). Similarly, the relay will open at the User input for AC1 V Lo Off. The voltage must meet the User input for DC1 V Lo On to close the relay.
(Insert graphs below to illustrate this explanation, Kelly, I will give you a hand drawn diagram).To change one of the settings, scroll to it and press Select. Press the LEFT "←" or RIGHT "→" arrow buttons to change the Voltage value and then press Enter to save the setting. Press Cancel to cancel a change.
Note: Lower threshold settings cannot be set above higher voltage threshold settings. Similarly, higher voltage thresholds cannot be set below lower voltage thresholds. The meter will automatically increase or decrease the voltage thresholds to enforce this.Clearing Relay Notification
If the Notification option is set to ON then any time the relay is opened (Normally Off) or closed (Normally On). A message will be displayed on the main screen. Pressing a key will clear this notification. If Silence is set to ON then the relay will be opened (Normally Off) or closed (Normally On).

When this option is selected, the meter will consider the battery’s present State-of-Charge to be FULL. To do this, scroll to Ok and press Select. The screen will then return to the meter summary display.
Battery Voltage (PN 1830 Only)
This setting indicates the nominal voltage of the battery. The options are 12V, 24V, 36V, & 48V.
Bat. Type (PN 1830 Only)
This setting indicates the battery type. The available options are as follows:
- FLStd - Standard Flooded Lead Acid Batteries
- AGM - Standard Absorbed Glass Mat (AGM) Batteries
- TPPL - Thin Plate Pure Lead AGM Batteries
- GEL - Gel Batteries
- FLRsv - Flooded Acid Reserve. Premium Flooded Lead Acid Batteries such as Rolls.
- FLLoM - Flooded Low Maintenance. Sealed Flooded Lead Acid Batteries
Bat. Capacity (PN 1830 Only)
This setting indicates the capacity of the battery in Amp-hours. The available range is 0 A to 5000 A.
Full Chrg Volts (PN 1830 Only)
This setting indicates the voltage at which the battery is considered to be fully charged. The available range is 0.1 V to 70.0V. This should be set to the absorption voltage of your charger. If you don't know the absorption voltage, you can figure the absorption voltage out by observing the output voltage of the charger once it enters the absorption phase. If you have multiple charging sources, set it to the higher absorption voltage. In extremely hot or cold temperatures the absorption voltage will need to be set slightly higher (for cold) or slightly lower (for hot).
Full Chrg Amps (PN 1830 Only)
In addition to Voltage, the user can set the Charging Current at which the battery is considered fully charged. The value is a percentage between 0.0 % and 10.0 % of the battery’s set Amp-hour capacity. This value should be set to 0.2% higher than the End of Absorption Amps. That is the current where the battery charger switches from Absorb to Float stage. Values are typically 2% for AGM and 3% for Lead Acid. As a battery ages, this percentage may need to be increased.
Charge Eff. (PN 1830 Only)
This setting is for indicating the battery's percent charge efficiency. The value may be set between 0% and 100%.
Shunt Value (PNs 1830 & 1834 Only)
The M2 is shipped with a single 500A/50mV shunt (the ratio is 10000:1). The shunt value assumes that the full scale shunt output voltage is 50 mV. To use a shunt with a smaller output voltage use the following formula: Shunt Value = (New Shunt Ratio) / 20. For example to use a 400A/20mV shunt (Note: 20mV = 0.02V), you would set Shunt Value to (400A/0.02) /20 = 1000A.
Zero Shunt (PNs 1830 & 1834 Only)
Menu->Setup->DC1 Setup->Zero< Shunt. To zero out the shunt, connect both of the current sense wires to the negative bus bar side of the shunt. Then press the reset button on the M2 Meter to confirm the action.
State of Charge(SoC) Cycles (PN 1830 Only)
Menu->Setup->DC1 Setup->SoC Cycles. The SoC Cycles option allows the user to reset the battery’s recorded SoC cycles to 0. To do this, scroll to and press Select on SoC Cycles. Text will then appear asking to confirm or cancel the reset request. Press Yes to confirm or No to cancel the action. Note: This function does not work in Version 1 of the Firmware.
State of Charge(SoC) Default Settings
To reset the battery’s State-of-Charge settings to the default values, scroll to and press Select on SoC Defaults. Text will then appear asking to confirm or cancel the reset request. Press Yes to confirm or No to cancel. The following changes will occur after a reset:
- SOC Cycles will be reset to 0
- State of Charge is Reset to 98%
DC2, DC3, DC4 Setup

Turn the channel on or off. If Enable is set to OFF then the channel will not be displayed when scrolling through the main menus. The alarms and relay functions for that channel will not be disabled. To disable the alarm and relay for a channel, set the alarm and relay for each channel to OFF.
Toggle A/V
Switch the Current and Voltage display on the channel's Summary Screen. If this option is set to OFF then Voltage will be displayed in the center field. If the option is set to ON then Current will occupy the center field.
viewfile?j=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUExample: Toggle A/V Set to OFF
Full Scale Amps
The M2 is shipped with a 150A AC/50mA AC Current Transformer (the ratio is 3000:1). The full scale output is based on transformers with a maximum output value of 50mA AC. A different value transformer can be calculated with the following formula: Full Scale Amps = New Ratio / 20. For example to replace the standard transformer with a 100A/20mA transformer (Note: 20mA = 0.02A): (100A/ 0.02) /20 = 250A.
