Connect the mains to the motherboard (PCB)

Connect mains

Pull wiring through the cable entry on the cabinet.

Before connecting, the supply circuit should be disconnected and voltage-free. Verify that the conductor area and cable type meet the applicable installation rules and that the strain relief and insulation levels comply with the requirements for 230 V AC

After connection, all screw connections should be checked and tightened. Tensioning shall only take place after mechanical protection, caps and housing have been reassembled and comply with the contact protection according to EN 62368-1

Secure F and N with cable ties.

Important

Protective earth (PE) must be connected to the PE terminal on the motherboard. The motherboard is grounded via its mounting points in the enclosure, ensuring proper potential equalization between PCB and enclosure. Also the cover is grounded through ground cable/earth braid between cover and enclosure to maintain continuity and EMC

Mains wiring must be kept separate from other wiring to avoid EMC interference.

The protective earth (PE) must be connected to the PE terminal on the motherboard. The motherboard is grounded via its mounting points in the enclosure, ensuring correct equipotential bonding between the circuit board and the enclosure. The cover is also grounded via a grounding cable / grounding braid between the cover and the enclosure to maintain continuity and EMC function.

Check that the marking on the circuit board matches the wiring order on the terminal block.

Battery test (dip 8)

To do a battery test, dip 8 needs to change position and five seconds need to pass before the test is initiated.

  • If dip 8 in original position is on OFF then switch dip 8 to: ON (wait 5 seconds) and then switch back to OFF.

  • If dip 8 in original position is on ON then switch dip 8 to: OFF (wait 5 seconds) and then switch back to ON.

This activates the battery test after 3-8 seconds. The battery test lasts for about 6 seconds and then the LED flashes yellow quickly. Aged battery alarms may be indicated while the battery test is being performed.

Only reset dip 8 when the test is complete.

Reboot to confirm changes in address, battery and alarm settings to parent system

After the dip-switch has been set for various parameters, the device's software needs to be restarted. This is for the new settings to be stored and take effect.

Important

Rebooting according to this procedure does not   interrupt the output voltage.

Restarting the device software is done by jumpering J11 (PRO3)

In the event of a change of address, the card should be reset once more after 20-30 seconds.

Important

Reboot must be done every time a change is made to the device.

NEO cannot be connected to communication/UC.

Reset after battery replacement -PRO3

After battery replacement, the device needs to measure the capacity of new batteries and clear previously set battery capacity. All alarms are cleared from the units memory, statistics remains and can not be cleared.

  • Insert jumper on J11 and remove jumper on J11

After doing step, the battery capacity is cleared in the units memory and is ready to read the new battery capacity.

This procedure needs to be done each time the batteries are replaced or when connecting a battery box.

Note on test of batteries

At start-up, it takes 72 hours before the system performs battery tests. This is to ensure fully charged batteries and to collect averages / history for at least 72 hours. Thereafter, every four hours, a qualified cell sample of the batteries is performed.

Note on start-up with short-circuited batteries

Peak current at start-up with short-circuited batteries: Up to 30 A p-p for 200 ms. Always follow the start-up procedure.

Adjustment of tamper switch

SABK_PLIERS_INSTRUCTION.eps

The tamper switch lever must be in the closed position when the cabinet door is closed. If the alarm goes off ("tamper alarm"), the lever may needs to be adjusted.

The lever is adjusted by the following steps:

  1. Pinch with pliers in the middle of the lever.

  2. Carefully adjust the lever in the desired direction (up / down).

  3. Check by closing the door. A click is heard when the contact is closed.

Notice

Tamper switch will not give an alarm when closed and locked the door.

Maintenance

The system with the exception of batteries is maintenance-free when installed in an indoor environment.

Inspect the fan annually. The fan should rotate smoothly without any noise. Clean the fan from dust and dirt. The fan must be replaced if it does not rotate smoothly or is so dirty that it cannot be completely cleaned. If the fan does not work well, the air flow in the unit will be obstructed, whichcauses heat to build up inside the enclosure, which can lead to reduced battery capacity and to a significantly shorter battery replacement interval.

About batteries

Batteries generate electricity through a chemical process and there is thus a natural degradation of capacity. The biggest factor in battery life is temperature. The higher the temperature, the shorter the battery life. The date of manufacture stamped on the battery and the service life (as stated by the battery manufacturer). An ideal temperature is 20 °C both in operation and in storage. Higher ambient temperature greatly reduces the service life. Thus, actual lifespan varies when used. Batteries should be replaced after half specified (from the battery manufacturer) lifetime for safe operation. Batteries purchased through the manufacturer of the battery backup have a lifespan (from the battery manufacturer) of between 10-12 years with recommended replacement after 5-6 years.

battery change

  • If possible, disconnect mains (voltage) when replacing the battery.

  • Disconnect battery cables. Note how battery cables are mounted before removing them.

  • Remove battery fuse between batteries.

  • Insert and fasten the new batteries.

  • Connect the battery cables in the same way as before.

  • Connect battery fuse between batteries.

  • Switch on mains voltage. The indicator LED may not be green (up to 72 hours), until the batteries are charged.

  • Test the system by briefly disconnecting the mains voltage, (= the load is driven by the batteries), and then switch on the mains voltage again.

Battery recycling

All batteries must be recycled. Return to manufacturer or return to recycling station.

In case of troubleshooting, the voltage of the batteries can be checked using a multimeter. Measure each 12V battery separately over the plus and minus pole. Next, measure the entire battery group connected in series. Two 12 V batteries connected in series should provide approximately 24-27 V DC depending on the degree of charge and whether charging is in progress. If measured voltage is significantly lower than expected, check polarity, battery fuse and wiring between battery box and battery backup.

If the problem persists after these checks, contact Milleteknik support and provide the product name, serial number, and a brief description of the fault.

Wiring diagram and jumper

Alarms for tamper contact are connected in series and therefore the loop must be unbroken to the last battery box wiring. Jumper closes the loop on each wiring that goes from battery backup to battery box and in order for an alarm to be given on the tamper connector in the battery box, a yellow jumper on wiring must be cut. Do not cut the jumper on the last wiring in the battery box, as sabotage alarms will not be given in any connected battery backup or battery box.

Battery backup (NOVA FLX) with 4 battery boxes (NOVA FLX)

Inkopplingsschema_batterier_med_batteribox.psd

Tamper switch when using battery box(-es)

If one or more battery boxes have been connected to the unit, the tamper switch must be connected in series in order for alarms from all units to be given. It is important that the series connection ends at the last tamper contact. The series connection must start in the battery backup unit and return to the last battery box.

All tamper contacts must be in series for everyone to be part of the alarm chain. Therefore, the yellow cable that is in the jackable connector must be cut on all connecting cables, except the last on. The cable must not be cut on the last connection / battery box.

Backup operating time on batteries

The reserve operating time in battery operation depends on how large a load is connected to the power supply. If the load varies, as with frequent opening of door locks, the time that batteries can continue to power the security system decreases. To get an estimate of reserve operating times see: www.milleteknik.se/Manualer/FaQ/Reservdrifttider/
