Foreword

M-series are monitoring units for DC-systems with voltage range 9 – 300 VDC.

For monitoring of DC-voltage, DC-current, earth fault and AC-voltage and also triggering of

battery test. Settings are easily made with buttons on the front panel and momentary

value/setting is shown in the display. For advanced settings there is a service menu.

M-series is available both as 19” and wall-mount.

Installation Wall

Unpack

Open box and find follow parts:

1 pcs. monitoring unit M-series

1 pcs. manual

1 pcs. set of male connectors for connection inside

1 pcs. connected cable for earth fault sensing

Option: 2 pcs. of brackets for door-mounting incl. screws and washers

Wall-mounting

Unscrew the screws on the four sides and remove the front panel. Fasten the back side

against the wall by using the four holes at each corner inside. Connect the cables for safety

earth (preferably the same screw as for earth sensor), DC-power and signaling. Use the wire

pull protections. Finally fasten the front panel again with the four screws.

Door mounting

Unscrew the screws on the four sides and remove the front panel. Fasten the mounting

brackets (option) with the screws. Fasten the front panel against the door. Connect the

cables for safety earth (preferably the same screw as for earth sensor), DC-power and

signaling. Use the wire pull protections. Fasten the back side using the screws.

Never do a high-pot test without disconnecting the earth fault sensor cable.

Disconnect this cable before doing the test.

Connections left

Illustration for M300 19”. M100/200 has fewer connections which is shown by the label on

the unit. The wall model has the corresponding connectors internally as the 19”. For

connection of the safety earth on Wall model use the same screw as for earth fault sensing.

Mains alarm relay in/out (only M300), Used with

external main fault relay. UT gives 5V which are

connected to the relay and returned to IN. The input

can be inverted with a setting in the service menu. Do

not use at the same time as AC-input (see below.

Shunt +/- (only M300), for connection of current

shunt. The shunt must be connected to minus side.

Different values for shunts can be used. Max 60mV.

The unit is precalibrated for 100A/60mV. Calibration

for other shunts are made in the service menu.

Earth fault sensing, connects to the safety earth bolt.

Disconnect when doing hi-pot test.

DC, for powering the unit and for measuring of DC-

voltage. Depending on model: 9-36VDC, 30-75VDC or

70-300VDC.

AC N and L (only M300), for connecting of mains

voltage to measure voltage level and mains fault. Not

used for powering the unit. Do not use at the same

time as external main fault relay (see above).

Earth stud, connection of safety earth and earth fault

sensor.

Front panel

Below is explanation of front panel. The different models in the M-series are different in form

and function and all features may not be present on delivered unit.

Measurement connectors, display, display indicators and display button

Alarm indicators and the battery test indicator

Buttons for choosing what to display

Indicators for what is displayed

The display shows momentary values or adjustment

value (by pressing adjustment button. VDC: 0-

300VDC. ADC: depends on shunt. KΩ(+)KΩ(-): 0-

1000KΩ, above 1000KΩ display shows ”----”. VAC:

0-250VAC, above 250 VAC display shows ”----”.

Earth connector (not for safety earth)

Measurement connector for V-meter. Short circuit

protected.

Red alarm indicators. Flashes when each alarm

has been triggered. If set delay is reached the

indicator goes into latched state (and the relay is

closed) and does not stop flashing until the alarm

is gone and the reset-button is pressed. Note:

battery fault goes into latched state instantly

without delay. Automatic resetting (no latching)

can be enabled in the service menu.

Yellow battery test indicator. Flashing when

battery test is in progress. Manually started or

auto.

Buttons

B-test: Start/stop battery test. If no battery

test is in progress the battery test is started

with the length that is set by using the

”length-button”. If pressed while battery test

is in progress the battery test is stopped.

Both manual and automatically started tests

can be stopped.

Reset: Alarm reset. Flashing alarm

indicators with no alarms active stops

flashing.

I-val: Battery test interval. For setting of

time between start of battery tests.

Possible: Off, 1 day, 30 days, 90 days and

180 days.

Length: Battery test length. Possible: 5 sec

(circuit test), 15 min, 30 min, 1 hour, 2

hours, 4 hours.

Level buttons for earth fault, high DC

voltage, low DC voltage 1 and low DC

voltage 2.

Earth fault: 50-1000Kohm.

High DC voltage, low DC voltage and low

DC voltage 2: 1-300VDC

Delay buttons. Delay of earth fault, mains

fault, high DC voltage, low DC voltage 1

and low DC voltage 2. Possible: 1-1800

sek. Above 1800 sec blocks the alarm and

is indicated with ”bloc” in the display.

Blocking blocks both alarm indicators and

relay.

Service menu

The service menu is used for calibration and other settings. It is used when testing the unit

before leaving the factory and can be used when the installer wants to adapt the units in a

more advanced way than is being offered by only using the normal settings. Use the service

menu with care.

Enter/exit the service menu and navigation

Enter the service menu by holding in the level

buttons for high DC voltage and for low DC voltage

2. The display shows an animation. Keep holding

the buttons until ”On” is displayed. Release the

buttons. The number ”0” is shown which is the

service menu.

Navigate to the menus with +/-. Then push the

button “Display” and use +/- to change the setting.

Available menus are listed on next page.

The service menu is exit the same way as it is

entered. By holding in the level buttons for high DC

voltage and for low DC voltage 2. The display

shows an animation. Keep holding the buttons until

”Off” is displayed. Release the buttons.

The service menu is automatically shut off after 5

minutes of no button presses.

Calibration of DC-voltage.

Connect calibrated V-meter in the V-meter output. Press Display button and use +/- to set

the same value in display as the V-meter is showing. Release Display button. Calibration is

finished. Calibration of earth fault display is recommended after calibration of voltage. The

unit is calibrated before delivery from factory.

Calibration of earth fault.

Check that no earth fault is present or disconnect the earth fault sensing cable. Press

Display button (without holding) to start the calibration. The display shows an animation and

the calibration is done automatically. The calibration is done when “done” is shown in the

display. Make sure the calibration if DC-voltage is done before calibration of earth fault. The

unit is calibrated before delivery from factory.

Calibration of current display zero-value (only M300).

This menu is not active in units with firmware ver. 102 and later. The Display button can be

pressed and Done will be shown in order to replicate earlier versions but it doesn’t do

anything.

Calibration of current display (only M300).

Use calibrated A-meter as reference. Increase the current over the shunt to max. Press

Display button and use +/- to set the same value in the display as the A-meter is showing.

Release Display button. The calibration is now finished. If the display current value is still not

correct try calibrating the zero-value first and retry calibrating the current display. The unit is

calibrated for a 100A/60mV shunt from factory.

Calibration of mains voltage display (only M300).

Connect external V-meter to the main voltage. Press Display button and use +/- to set the

same value as the V-meter is showing. Release Display button. The calibration is now

finished.

The unit is calibrated before delivery from factory.
