Installation

Requirements
Power supply units are to be mounted by a qualified installer, holding relevant permits and licenses (required in installation country) to connect (interfere) with ~230 V mains supply. Because power supply units is designed for the continuous operation and is not equipped with ON/OFF switch, the power supply circuit should have the appropriate overload protection. Moreover, the user shall be informed about the method of unplugging (most frequently through separating and assigning an appropriate fuse in  the fuse-box). The electrical system shall follow valid standards and regulations. The PSU shall work in a vertical position that guarantees sufficient convectional air-flow through ventilating holes of the enclosure. As PSU cyclically runs a periodic battery test, during which resistance in battery circuit is measured, pay attention to proper connection of cables to terminals. Installation cables should be firmly connected to battery side terminals and to power supply connector. If necessary, it is possible to permanently disconnect battery from power supply systems by removing FBAT fuse. PSU is protected from access to configuration menu by two-level access passwords. If, during installation, modification of factory settings is required then access must be unlocked by entering the installer password – Table 9 and section 7.1.

Installation procedure.

CAUTION!
Before installation, cut off voltage in ~230 V power-supply circuit. To switch power off, use an external switch, in which the distance between contacts of all poles in disconnection state is not less than 3mm.

It is required to install in the supply circuits, in addition to the power supply, a circuit breaker with 6 A nominal current.

1. Mount the PSU in a selected location.

2. Connect power cables ~230 V to L-N clips of PSU. Connect the ground wire to clip marked by earth symbol .

   • Use a three-core cable (with a yellow and green protection wire ) to make the connection. Wires should be desolated to a length of 7mm.
     Shock protection circuit shall be done with a particular care: yellow and green wire coat of power cable should be connected to terminal marked with grounding     symbol on PSU enclosure. Operation of PSU without properly made and fully operational shock protection circuit is UNACCEPTABLE! It can cause damage to equipment or an electric shock.

3. Connect receivers’ cables to AUX output terminals.

4. If needed, connect cables from devices to technical inputs and outputs: – APS; technical output of battery failure – EPS; technical output indication of 230 V power collapse (alarm control panel, controller, indicator, etc.).

   • PSU; the technical output of the collective failure of PSU – EXTi; input of external failure
   • TAMPER; contacts of antisabotage protection

5. Install battery/batteries in a designated area of the enclosure. Connect batteries with PSU paying special attention to correct polarity and type of connections (Fig. 4):

6. Fig. 4. Connecting batteries depending on voltage version of power supply: a) power supplies 12V version, b) power supplies 24V version

7. Screw terminals of temperature sensor to “Temp” terminals of PSU (figure 2, point 3). Attach sensor to the battery, e.g. with adhesive tape. For the 27.6V version, it is recommended to place the sensor between batteries.

8. Switch on ~230 V supply. The corresponding LEDs on the power supply PCB should be ON: green 230 V AC and above AUX connectors.

9. Check the current consumption of receivers, taking into account battery charging current, so as not to exceed the total current efficiency of the PSU (see section 2.1).

10. Once the tests and control operation have been completed, close the enclosure.

11. Close the power supply cover after testing and operation control.

Procedure for checking power supply module on installation site.

1. Check indication displayed on printed circuit board of power supply:
   • 230 V AC LED should remain lit to indicate the presence of mains supply voltage.
   • LED above AUX connectors lights up to indicate the presence of output voltage.
2. Check output voltage after 230 V power failure.
   • Simulate lack of 230 V mains voltage by disconnecting the main circuit breaker.
   • 230 V LED should go out.
   • LED above AUX connectors lights up to indicate the presence of output voltage.
   • LED ALARM LED will start blinking.
   • EPS technical outputs will change status into opposite after time 11 s.
   • Turn on 230 V mains voltage again. Indication should return to the initial status from point 1 after about 11 seconds.
3.  Check whether lack of continuity in battery circuit is properly indicated.
   • During normal PSU operation (230 V mains voltage on), disconnect battery circuit by disconnecting FBAT fuse.
   • Within 5 minutes PSU will start signalling a failure in battery circuit.
   • LED ALARM LED will start blinking. APS technical output will change status into the opposite.
   • FBAT fuse in battery circuit again.
   • Power supply should return to normal operation, indicating initial status, within 5 minutes after battery test is completed.

Functions

Technical outputs
PSU module is equipped with indication outputs OC type changing status after a specified event:

EPS – output indicating 230 V power loss.
The output indicates 230 V power loss. Under normal status – with 230 V supply on, output is closed. In case of power failure, PSU will switch output into open position after a time about 11 seconds.

APS – output indicating battery failure.
The output indicates the PSU failure. Under normal status (during correct operation) the output is closed. In case of failure, the PSU will switch the output into the open position. Failure can be triggered by the following events:

• defective or low battery
• battery voltage below 23 V or 11,5 V (depending on the voltage version of the power supply) during battery operation
• battery fuse failure
• no continuity in the battery circuit

PSU – output indicating PSU failure.
The output indicates the PSU failure. Under normal status (during correct operation) the output is closed. In case of PSU failure, it will switch into the open position. PSU failure can be caused by the following events:

• low UAUX output voltage, less than 23 or 13 V – depending on the voltage version of the power supply
• high UAUX output voltage, higher than 28,4 or 14,2 V – depending on the voltage version of power supply
• exceeding power supply output current
• battery charging circuit failure
• internal damage of PSU
• activation of the EXT IN input
• to high battery temperature (> 65°C)
• temperature sensor failure, t < -20°C or t > 80°C

The power supply technical outputs are open collector (OC) type, as shown schematically below.

If it is necessary to use technical relay outputs, the AWZ642 relay module should be used.

Collective failure input EXT IN.
EXT IN (external input) technical input indicating collective failure is intended for additional, external devices that generate failure signal. The voltage appearing at the EXT IN input will trigger PSU failure, storing the information about the event in the internal memory and sending the signal about the failure to the PSU output.
The connection of external devices to the EXT IN input is shown in the electrical diagram below. OC outputs (open collector) or relay outputs can be used as the source of the signal.

The EXT IN input has been adjusted to work with fuse modules generating a failure signal in case of blown fuse in any of output sections (e.g. AWZ536). To guarantee a correct cooperation between the fuse module and the EXT IN input, the connections shall be made as presented in the diagram below .

Optical indication.
PSU is equipped with LEDs on PCB indicating PSU operation status:

ALARM LED flashes specified number of times to indicate failure code according to table below. If PSU has several failures at the same time, they are all indicated consecutively.

Table 3. Coding of PSU failure by number of ALARM LED flashes on PCB of PSU.

Failures are also indicated on the LCD panel (see section 6.4.3.)

Indication opening enclosure – TAMPER.
PSU is fitted with tamper microswitches indicating enclosure opening and detaching from the surface. The contacts of microswitches are normally closed, and their wires must be connected to input of control panel, etc.

PSU overload.
PSU is equipped with an output overload protection circuit. If a rated current of PSU is exceeded, the microprocessor will switch to a specially implemented procedure and signal failure on PSU output and ALARM LED on PCB. Depending on duration and level of PSU overload, microprocessor may put PSU into battery operation mode. After overload has stopped, PSU will resume correct operation. An overload status of the PSU is indicated by changing status of PSU technical output and blinking of ALARM LED on the PCB.

Reserve power supply circuit.

PSU is fitted with circuits: charging and battery control whose main task is to monitor the state of the battery and connections in its circuit. If the controller detects a power failure in battery circuit, appropriate indication and change of APS technical output.

Running PSU on battery backup.
PSU has been fitted with a button on PCB to enable activate battery operation of PSU if required. Activation of PSU from battery: to do that, press and hold the START button on the unit board for 1 second.

Deep discharge battery protection UVP.
PSU is fitted with a disconnection system and battery discharge indication. During battery operation, lowering voltage below 10 V +/-0.2 V (20 V±0.2 in 27.6 V version) will disconnect battery within a few seconds. Batteries are reconnected to power supply unit automatically once ~230 V mains supply is restored.

Battery test.
The PSU runs a dynamic battery test every 5 minutes, temporarily switching the receivers to the battery operation mode. During testing, the control unit of the PSU measures the electrical parameters according to the implemented measuring method. Negative test result will occur as soon as continuity of battery circuit is broken, or if the voltage drops below 12 V or 24 V (depending on the version of the PSU). The battery test function will also be automatically blocked if the PSU is in a working mode in which running of the battery test would not be possible. This condition occurs, for example, during battery operation or when PSU is overloaded.

Measurement of resistance of battery circuit.
PSU is checking resistance in the battery circuit. During measurement, the PSU driver takes into account key parameters in circuit, and once limit value of 300m ohms is exceeded for 13,8 V version or 350 mΩ for 27,6 V version, a failure is indicated. A failure may indicate considerable wear or loose cables connecting batteries.

Battery operating temperature readings.
Temperature measurement and compensation of battery charging voltage can extend life of batteries. PSU has a temperature sensor to monitor the temperature parameters of installed batteries. Attach sensor to battery, e.g. with adhesive tape. For the 27.6V version, it is recommended to place sensor between batteries. Be careful not to damage the sensor when moving batteries.

Standby time.
Battery-assisted operating depends on battery capacity, charging level and load current. To maintain an appropriate standby time, current drawn from the PSU in battery mode should be limited.

Remote monitoring (option: Ethernet, RS485).

PSU has been adjusted to operate in a system that requires a remote control of parameters in a monitoring centre. Transmitting information about the status of the PSU is possible by using an additional, external communication module realising communication in the Ethernet or RS485 standard. The various connection topologies presented in the following section constitute only a part of the possible communication schemes. More examples can be found in the manuals dedicated to the individual interfaces. When installing optional features in power supply unit, power supply current consumption, used for calculation of standby time, should be taken into account (see section. 5.6).

ETHERNET network communication.
Communication in Ethernet network is possible due to additional interfaces: Ethernet „INTE-C” and RS485-ETH „INTRE-C”, according to IEEE802.3 standard. Ethernet „INTE-C” interface features full galvanic isolation and protection against surges. It should be mounted inside enclosure of PSU.

RS485-ETHERNET „INTRE-C” interface is a device used to convert signals between RS485 bus and Ethernet network. For proper operation, unit requires an external power supply in range of 10-30 V DC e.g. drawn from a PSU of HPSG3 series. Unit is mounted in a hermetic enclosure protecting against adverse environmental conditions.

„PowerSecurity” web application.
The PowerSecurity web application has been embedded in the INTE-C and INTRE-C communication interfaces. The programme is a website uploaded from an embedded WWW server which is loaded upon entering the IP address in the web browser window. Upon loading the PowerSecurity application, access is gained to the preview of the status of the PSU connected with an INTE-C interface, or to the preview of all PSUs in the RS485 bus in case of an INTRE-C interface. From the WWW browser level, the current status of the PSU can be checked, with preview of such parameters as output voltages, presence of 230 V supply, or resistance of the battery circuit. Moreover, the application has an option of interface configuration for the function of remote alerting through email notification including information on the status of the PSU in case of occurrence of specific events. The drawing below shows the appearance of a tab with the current PSU status.

The web application also has a graphic tab „Graphs” from which the PSU history of operation may be downloaded and viewed in the graphic form, as a graph. A read graph may be saved in a file on a disc.

Another tab enabling checking of the PSU history is the tab of events. The read history is displayed as a table, following a chronological order. From the table, we can read the exact time of occurrence of the event, the error code, the event type description, as well as electric parameters and the status of individual technical outputs.

The PowerSecurity programme provides functionality in the form of a remote battery test and the function of remote alerting via automatically sent email notifications. The notifications contain information on the current error codes, with the exact malfunction occurrence time. The email notifications are sent to 2 recipients. The service includes SSL encryption of the mail and authorization for the user’s verification through the outgoing mail system (SMTP) in order to ensure safety of the mail account. Time periods between alerts and types of initiating events are individually configured by user.

Technical inspections and maintenance.

Technical inspections and maintenance can be performed after disconnecting the power supply from the power network. The PSU does not require performing any specific maintenance measures, however, in the case of significant dust rate, its interior is recommended to be cleaned with compressed air. In the case of a fuse replacement, use a replacement of the same parameters. Technical inspections should be carried out not less frequently than once per year. During the inspection, check batteries and run battery test. 4 weeks after installation, re-tighten all threaded connections Fig. 2 [2].

Battery replacement of LCD panel.
The estimated operating time of battery type CR2032 is about six years. After this period, battery will need to be replaced. Battery replacement of the LCD panel should be done during mains operation or battery-assisted operation in order to avoid resetting the time settings.

CAUTION!
Removed batteries should be stored in a designated collection point. Do not reverse polarity of batteries. Improper use of battery may lead to explosion.

WE MARK
According to the EU WEE Directive – It is required not to dispose of electric or electronic waste as unsorted municipal waste and to collect such WEEE separately.

CAUTION! The power supply module unit is adapted for a sealed lead-acid battery (SLA). After the operation period it must not be disposed of but recycled according to the applicable law.
