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-reset-

ting 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.

External LED

An external LED such 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.

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

rst button is pressed.

The menu system is a two dimensional matrix. Pressing the UP ↑or DOWN ↓arrow buttons will transition the display between the System

Summary screen which displays summary information for each of the “tank” channels.

Press the Next button to display more detailed information about an input channel or to show a single parameter, such as “T1” in the display

(see example below).

Press the Menu button to bring up the Setup menus. Press the UP ↑and DOWN ↓arrow buttons to move the cursor over the options and press the

Select button to see a selected display. To return to the previous display, press the Back button.

Conguring the Meter

Meter settings can be congured 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, rst navigate to the Setup

menu. Then scroll to Alarm Setup and press the Select button.

Setting Alarms

The M2 Meter family provides monitoring capability of input channels. Alarms are triggered if a channel is above or below a certain user selected

threshold value. The following example indicates how to setup a tank full alarm.

1. Go to the Alarm Setup menu.

2. Scroll to the desired input channel (i.e., Tank 1 Hi).

3. Press the Select button and the cursor should start blinking.

4. Set the tank level threshold using the ← and → buttons. (Holding down the buttons allows faster selection)

5. Press the Enter button to save the change or the Cancel button to cancel any change.

NOTE: A low tank level threshold cannot be set above a high tank level threshold. Likewise, a high tank level threshold cannot be set below the low tank

level threshold. The meter will automatically increase or decrease the tank level thresholds to enforce this.

In the above example, an alarm will set anytime Tank 1 is greater than or equal to 90% of the full scale rating. This could be used to monitor a holding

tank or to indicate that a tank is almost full while lling fuel. Note that the display can be changed from % to gallons or liters in Tank 1 Setup.

Tank Alrm Dly (Alarm Delay)

An alarm delay can be specied so that alarms don’t immediately trigger. This can be useful if tank sloshing is causing false alarms.

The hold off timer operates as a count-up/count-down timer. When the tank value exceeds the alarm value then the timer will start counting up until it

reaches the delay time. When it reaches the delay timer, an alarm will sound. If the alarm condition goes away before the delay timer has been met, then

the timer will count down until the timer is zero again. For example, if the Alarm Delay is set for 5 minutes and an alarm condition is active for 4 minutes

and then inactive for 1 minutes then if the alarm condition is active again, the alarm will sound in 2 minutes (5 minutes - 4 minutes + 1 minute). Note that

there is only one delay per channel.

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 ash if it is displayed. To view a complete list of active alarms, press Menu>Setup>Alarm Setup. Any active

alarm will ash. You may have to scroll through the menu to see all of the alarms.

Relay Setup & Control

M2 Meters provide an option to control an external relay. The M2 can trigger the relay based on high or low tank levels.

These relay options can be set from the Relay Setup menu. To get there, rst navigate to the Setup menu. Then scroll to Relay Setup and press the

Select button.

Relay 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 ash), then press the

LEFT ←or RIGHT →arrow buttons to change the setting. Press Enter to save your selection. Press Cancel to cancel a change.

Notication

The Notication setting controls whether or not a notication is displayed when a relay is activated. Notications will show which relay threshold was

surpassed and for which channel. Scroll to Notication and press Select to change the setting. Press the LEFT ←or RIGHT →arrow buttons to choose

either ON or OFF. ON will display notications and OFF will not. Use this option if you don’t want to be notied that the relay is activating. Press Enter to

save the setting or Cancel to cancel a change.

Silence Relay

Turn this option on if you want the relay to de-activate after the user presses a key on the display. The key press will only de-activate the relay and

will not engage any functions on the meter. For example, this option could be used to silence an external buzzer. Scroll to Silence and press Select to
