NOVA, what does the indicator diode show?

Alarms and alerts from the device go in descending order from fast flashing red to solid green. This means that lower priority alarms and warnings can be hidden by higher priority flashes.

Example: Device is slowly flashing red (Low system voltage). The error is rectified and then the device lights up with a solid yellow light (Low battery voltage). The error is rectified and then the device flashes because the tamper contact is not active. When the cabinet door is closed, the last problem is thus remedied and the LED shows a solid green light.

Red fast flashes mask all other lower priority indications.

The alarm order in the example	Mean
	Low system voltage alarm masks Low battery voltage and tamper alarms. This is remedied and then:
	Alarm for low battery voltage masks alarm for tamper contact. This is remedied and then:
	Alarm for tamper contact is given. This is remedied and then:
	Lights up a steady green light, all ok.

Status means: The device is working normally.

Action: No action is required.

Note. for certain NOVAs manufactured before June 2021

For some NEO3/PRO3 units manufactured before June 2021, a software update may be required, if the output voltage is low even though the indicator LED is green.

Troubleshooting NEO3/PRO3 cards (Milleteknik's NOVA system as well as Stanley, Bravida, Vanderbilt).

1. Measure output voltage P1:1 and P1:2 (1). If the voltage is lower than 12 V / 24.0 V or if the voltage is lower than 13 V / 26.0 V and does not rise at least 0.1 V after 5 minutes, proceed to the next step.

2. Reset “J11” (2) (quick short circuit and system restarts). If the indicator LED flashes quickly orange (cell short circuit or disconnected batteries or very low batteries), call our support and order upgrade dongle. Have serial number available.

3. Measure the battery voltage on each battery with the battery fuse (3) disconnected and note the different pole voltages of the batteries. Battery replacement may be necessary but upgrading may not be necessary.

Status means: Alarm from the tamper contact.

Remedy: Check whether damage has been done to the device or that the tamper switch is correctly adjusted. If the battery box is connected, the yellow cable in the battery backup connector must be cut and in all battery boxes except the last battery box. Adjust tamper contact if necessary.

Troubleshooting: Keep the tamper switch pressed, then the tamper alarm should stop, if not check the jumpers on the motherboard.

Tamper switch adjustment

Adjustment of tamper switch

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.

Status means: Interruption of power supply (230 V) to the device.

Action: Fix network interruption. Check that the terminal for 230 V is seated properly and that there is mains voltage up to the jackable terminal.

Troubleshooting: Check if the mains voltage diode lights up with a solid green light on the circuit board.

Figure 4. PRO1 card (RCO and ASSA and Tidomat) or earlier systems by Stanley.

D1 LED should light up if 230 VAC is connected.

Figure 5. PRO2 short 15A and 25A (Milleteknik's NOVA system as well as Stanley, Bravida, Vanderbilt).

D12 LED should light if 230 VAC is connected.

Figure 6. PRO3 cards 5A and 10A (Milleteknik's NOVA system as well as Stanley, Bravida, Vanderbilt).

D1 LED should light up if 230 VAC is connected.

If the LED lights up green, there is mains voltage to the card and the processor registers it, otherwise measure with a multimeter AC voltage measurement on mains terminal P1:1 "Line"(Phase) and P1:2 "N"(Zero) that 230 VAC is present.

Status means: Battery voltage is low below 12 V / 24 V when the device is powered by batteries.

Action: Normal operating condition during long-term power failure and subsequent recharging of the batteries.

Troubleshooting: Troubleshooting does not need to be done when batteries are being charged.

Status means: Batteries need to be replaced, so that backup operating time can be safely maintained. Weekly battery capacity tests are carried out, over a built-in test load, to establish that the batteries are not outdated.

Check: That the temperature is not too high, above 25 °C, in the surroundings.

That any fan works/spins. It should be considered to also change the fan in connection with changing the battery.

Remedy: Replace all batteries with equivalent batteries in terms of life and capacity. Possibly replace the fan as well (its lifespan is 6-8 years depending on the ambient temperature).

After battery replacement, the alarm resets itself, may take up to a week. With reset, the alarm can be cleared immediately.

For battery replacement: read under section battery replacement in the installation manual

Troubleshooting: Measure battery voltage in mains operation across the battery terminals. 13.65 V / 27.3 V.

Disconnect all battery fuses in battery backup and battery boxes. Measure the voltage of each individual battery and record the value. The voltage must be over 13.3 V / 26.6 V on each battery. The differences between batteries must be less than 0.3 V.

Status means: Batteries are disconnected or battery fuse between the batteries switched off or cell failure in batteries which led to a short circuit in the battery.

Action: Check that all battery terminals are tightened and all battery fuses (one per battery box and in the main unit) are switched on.

Battery Troubleshooting:

1. Measure battery voltage with multimeter and with mains voltage and battery fuse switched on; note the total voltage value. Measure the battery terminal voltage, it should be higher than 12 V / 24 V (13.65 V / 27.3 V).

2. Measure battery terminal voltage to confirm that the batteries do not have a cell short circuit. Disconnect all battery fuses in battery backup and battery boxes. Measure the voltage of each individual battery and record the value. The voltage must be over 13.3 V / 26.6 V on each battery. The differences between batteries must be less than 0.3 V.

Status means: Problem with the power supply, it is providing too much or too little voltage or has received an internal error.

Action and Troubleshooting: Disconnect all batteries by disconnecting all battery fuses. Measure across the plus and minus poles of the power supply unit to check unit voltage. In case of larger deviation (more than -0.5 V and +0.2 V), measure the load with a current clamp / Ammeter, set to DC current and note that the current does not continuously exceed 80% of the rated capacity. If over 100% of the measurement capacity, install larger battery backups or distribute the load on more battery backups. Otherwise, in case of minor deviations, the voltage of the power supply can be adjusted via potentiometer to setpoint 13.65 V / 27.3 V.

After measurement: Reset battery fuses. Disconnect the mains voltage to verify that the battery backup works in battery operation.

Status means: The voltage from the battery backup is too low, (below 12.0V / 24.0V), which is a natural operating condition when recharging after a long-term power failure.

Action: If there has not been a longer power outage recently. Check that the load does not exceed the rated power of the battery backup and that the power supply is set correctly.

Troubleshooting: Measure the load with a current clamp / Ammeter, set to DC current and note that the current does not continuously exceed 80% of the rated capacity. If over 100% of the measurement capacity, install larger battery backups or distribute the load on more battery backups.

Disconnect all batteries by disconnecting all battery fuses.

Status means: Fuse for load or battery has tripped.

Action: Replace the fuse / switch on the circuit breaker or contacts on the circuit board become loose.

Troubleshooting: Check that battery fuses are intact or switched on. Check that the load fuses are intact, if the load fuses have tripped, check that there is no short circuit in the load. Green indicator diode lights up at each load output if the fuse is intact and there is voltage out.

2. JU2. Cable for battery fuses from external battery boxes on terminal "JU2", (NO). there is no battery box connected, no cable is connected to JU2. JU2 Does not need to be bridged. Pull this cable and if the alarm stops, then there is a fault with this cable or in non-activated battery fuses in battery box(es).

2.1. If alarm stops. Put the cable back and check that the automatic fuses in the battery box(es) are switched on.

3. J15. Check if external load cards are connected to J15 (NC). Loosen the cable, put a jumper so that the alarm from J15 cannot be given. If the alarm disappears when the jumper is inserted, the fault lies in the external load distribution board. Troubleshoot as below.

3.1 If the load card is not connected, J15 must be jumpered.

3.2 If load cards are connected to J13, pull this cable to check whether the fault is in cable or external load card. No jumper is needed. If the alarm disappears, the fault lies in the external load distribution board. Troubleshoot as below.

4. J13. Load distribution cards can be connected to J13 alt (J15) and further to load cards: 2 OUT LOAD J1 or J2 or 5 Output module J6 or J7 or 10 Output module J11 or J12 “.
