Warning and Caution Symbols

WARNING: The symbol refers to possible injury to the user or

signicant damage to the meter if the user does not follow the procedures.

CAUTION: The symbol refers to restrictions and rules with regard

to preventing damage to the meter.

WARNING

• If you are not knowledgeable about electrical systems, have an

electrical professional install this unit. The diagrams in these

instructions pertain to the installation of M2 Digital Meters and not

to the overall wiring of the vessel.

• If an inverter is installed on the vessel, its power leads must be

disconnected at the battery before the meter is installed.

• If an AC generator is installed on the vessel, it must be stopped

and rendered inoperable before the meter is installed.

• Verify that no other DC or AC sources are connected to the vessel’s

wiring before installing the meter.

CAUTION

• The back of the unit is not waterproof. Do not install where the back

of the meter is exposed to water.

Installation 1. Make all connections to the meter’s terminal block before connecting the terminal block to the unit. Keep hands away from the terminal block when applying power to the meter. 2. As the final DC connection, insert a fuse into the in-line fuse holder on the wire to the positive (+) battery terminal.

Tank Functions (1839) Monitor up to four tanks. Provides High/Low level alarms for each channel. Connections 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.

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. 4 Relay Supply Pin 4 voltage connections are only required if the relay is used.
PAGE 7
External Alarm (1070 Floyd Bell Turbo) The Relay+ terminal can support an external audible alarm. Such as the Floyd Bell Turbo Alarm (1070). External Alarm Supply 5 to 30V DC 1 2 3 4 5 6 7 8 + Red - Silver 1070 External Relay If you need to switch more than 0.5 A, you can use an external relay such as PN 7713, 12V or PN 7717, 24V Remote Battery Switch. Connect the Relay+ terminal to the red control wire. Activating the internal relay will also activate PN 7713.

Getting Started Example Screens From PN 1839 Tank Meter When an M2 Meter is initially powered up, it will display the Blue Sea Systems Logo,its serial number and its Software revision. After a couple of seconds, the unit will display a high-level System Summary screen. Pressing any button will display a temporary pop-up menu. Select an option by pressing the button beneath it. The pop-up menu will disappear after the first button is pressed. The menu system is a two dimensional matrix.
PAGE 9
Configuring the Meter Meter settings can be configured from the Setup menu. This menu can be accessed by pressing the Menu button and then scrolling to and selecting Setup. Press the UP ↑ and DOWN ↓ arrow buttons to move the cursor. The different setup options are described below. Alarm Setup & Control The meter’s alarm can be set to trigger for full or empty tanks. Alarms can be set from the Alarm Setup menu. To get there, first navigate to the Setup menu.
PAGE 10
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 will blink. Viewing Alarms Status For any active alarm, the parameter will flash if it is displayed.
PAGE 11
Setting Input Thresholds Settings for each channel’s high and low tank 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 levels 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.
PAGE 12
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). Viewing Relay Status For any active alarm, the parameter will flash if it is displayed. To view a complete list of active alarms, press Menu>Setup>Relay Setup.
PAGE 13
Changing System Labels The M2 allows the user to change the labels that are displayed above each channel. Each channel can have a maximum of 16 characters however in the summary screens only the first 11 or 12 characters of the channel label are displayed. Changing Label Names To change the name of a tank, follow the instructions below: 1. Navigate to the setup menu for the desired tank (such as tank Setup). Menu->Setup->Tank 1 Setup 2.
PAGE 14
Tank Depth (Only used with 1810 and 1811 Senders) This setting indicates the depth of the tank in inches. This setting is not affected by switching the units in Setup->Display->Units. Tank Shape • • • • Rect – Standard Rectangular Tank Tri – Triangular Shaped Tank. Good for tanks in Bilges. Auto – This setting only shows up after the tank has been auto calibration. Changing this value back to Rect or Tri will overwrite the auto-cal values.
PAGE 15
Using Auto-Calibrate The Auto-Calibrate function requires the tank to be filled at a constant rate and for the sensor reading be initially less than 15%. For grey, waste, and water tanks a hose can be used to provide a constant flow. Diesel and Gas tanks can be more difficult because foaming may cause the user to slow down filling once the tank is almost full. If foaming is a problem then use the Manual method described above. 1. Select Setup->Tank(1-4)->Auto Calibrate->Ok 2.
PAGE 16
Software Upgrade The meter firmware can be updated in one of two ways. The first option is to use the Software Upgrade option in the Setup menu. The second option is to force the meter into upgrade mode on startup. Each method involves using a USB memory stick connected to the USB port on the back of the meter. The USB port is a type A/B micro USB port. This port is also known as a Micro USB Host OTG. Available at Best Buy or Amazon: http://amzn.
