www.pulsar.pl PSBEN5024C BLACK POWER 4. Installation. 4.1 Requirements. The PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and required for a given country) for ~230 V in and low-voltage installations. As the power supply is designed for a continuous operation and is not equipped with a powerswitch, therefore, an appropriate overload protection in the power supply circuit should be provided.
www.pulsar.pl PSBEN5024C BLACK POWER off. The battery protection is on when the PBAT jumper is off. 7. Switch on the ~230 V supply (red AC diode and green AUX diode should be on). 8. Check the output voltage (the PSU voltage without load and without battery should amount to 27.5 V÷27.7 V, with a battery or during battery charging process: 22 V÷27.6 V). If the value of the voltage requires adjustment, it should be set with use of the VADJ potentiometer, monitoring the voltage at the AUX output of the PSU.

The panel buttons are used to select and confirm the parameters, which should be displayed. Fig. 5. Control panel. Table 5. The description of the buttons and LEDs of the LED panel.
www.pulsar.pl BLACK POWER PSBEN5024C 5.2 Main menu. The PSU is equipped with a menu, which allows to preview the current electrical parameters. The diagram explaining the menu structure is presented below. Fig. 6. The menu of the display. Table 6. The description of display symbols. Symbol Description AUX output voltage [V] Additional information Factory setting 27,6 V Output current [A] Failure history Section 5.2.3 Current failures Section 5.2.
www.pulsar.pl PSBEN5024C BLACK POWER The PSU stores 30 last failures in non-volatile memory, which can be reviewed later. In order to review the failures, use the "<" or ">" button to set the FLh parameter and confirm by pressing "OK". The display will show the number of failure in the memory and its code. Pressing the "OK" button again will display the next failure in the memory.
www.pulsar.pl PSBEN5024C BLACK POWER - press „<” or „>” button to set the „FLc” parameter on the display „FLc” - press „OK” button - the number 1, indicating the number of failure in the memory (the highest priority), will be displayed. Then, after one second, failure code will be automatically displayed - press „OK” button - the number 2, denoting the next number of failure in the memory, will be displayed. Then, after one second, the next failure code will be automatically displayed.

www.pulsar.pl BLACK POWER PSBEN5024C 5.3 PSU configuration. The PSU is equipped with a configuration menu that allows to configure the settings by changing or the activation of some of its parameters. The figure illustrating the configuration menu structure is shown below. Fig. 7. The PSU configuration menu. Table 10. Description of symbols.
www.pulsar.pl 5.3.1 BLACK POWER PSBEN5024C Battery test ON/OFF „tSt” The "tSt" function allows to enable or disable the test of the battery (Section 6.3) connected to the power supply. When activated, the battery test occurs automatically if it is not blocked by the control system (section 6.3).
www.pulsar.pl BLACK POWER PSBEN5024C LED display dimmer allows to dim the display if no buttons are pressed within 5 minutes.If the display is in the blackout mode, pressing any button will "reactivate" the display.
www.pulsar.pl BLACK POWER PSBEN5024C - press „OK” - the current address of the PSU will be displayed - use the „<” or „>” buttons in order to set the address 1÷ 247 – address of the PSU during the communication with the computer - confirm by pressing „OK” - in order to return to the main menu, simultaneously press the „<,>” rightmost and leftmost buttons 5.3.4 Setting the transmission speed „trS” applies to cooperation with PowerSecurity.
www.pulsar.pl BLACK POWER PSBEN5024C All the parameters responsible for communication between the PSU and the computer, namely the address, parity and speed should have the same settings for both the PSU and the PowerSecurity program. The PSU has preset transmission parameters of 115200 baud 8E1. However, if it is connected to the network with differently defined parameters, make the appropriate changes to its configuration.
www.pulsar.pl PSBEN5024C BLACK POWER 5.5 Technical outputs. The PSU feature indication outputs, with galvanic isolation, which change their state if any of the following events occur: EPS FLT - output indicating 230 V power loss. The output indicates 230 V power loss. Under normal status (with 230 V supply on) the output is closed. In case of power failure, the PSU will switch the output into the open position after a time lag set by the TAC jumpers (J1, J2).
www.pulsar.pl PSBEN5024C BLACK POWER The electrical diagram below shows the way of connecting external devices to the EXT IN input. Outputs such as: OC (open collector), relay may be used as a source of the signal. Fig. 10. Examples of connections. In the option with tamper switches, the VEXT jumper must be on. It polarizes the EXT IN input circuit therefore is required in such configuration.
www.pulsar.pl PSBEN5024C BLACK POWER In case of voltage exceeding 31 V±0.5 V at the switching regulator’s output, the system cuts off the power at the outputs to protect the battery and the receivers from damage. The outputs will be battery-powered. The activation of the protection system is indicated by the OVP yellow LED on the PCB board, and the PSU FLT output. 5.9 PSU overload. The PSU is fitted with the LED OVL (overload) on the PCB and indicator on the LED panel, informing about output overload.
www.pulsar.pl PSBEN5024C BLACK POWER 6 Reserve power supply circuit. The power supply is equipped with intelligent circuits: charging and battery control circuit, whose main task is to monitor the condition of the battery and its connections in the circuit. If the power supply driver detects a malfunction in the battery circuit, appropriate signaling and change in the APS FLT technical output take place. 6.1 Running the PSU from the battery.
www.pulsar.pl BLACK POWER PSBEN5024C 6.4 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. Characteristics for a 2x17 Ah/12 V SLA: Grade 1, 2 - standby time 12h Output current 1,4 A + 3 A battery charge Grade 3 - standby time 30h if the faults of the main power source are reported to the Alarm Receiving Centre - ARC (in accordance with 9.
www.pulsar.pl PSBEN5024C BLACK POWER 7. Remote monitoring (options: Ethernet, RS485). The PSU has been adjusted to operate in a system that requires a remote control of the parameters in a monitoring centre. Transmitting data concerning PSU status is possible due to an additional, external communication module responsible for communication in Ethernet or RS485 standard. Different connection topologies, presented later in this chapter, are only a part of possible communication schemes.

www.pulsar.pl PSBEN5024C BLACK POWER 9. 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 any specific maintenance; however, its interior should be cleaned with compressed air if it is used in dusty conditions. In case of fuse replacement, use only compatible replacement parts. Technical inspections should be carried out not less frequently than once per year.
