The PSU is fitted with intelligent circuits: battery charging circuit with the function of the accelerated charging and battery control, which main task is to monitor the condition of the batteries and the connections in the circuit. If the controller detects a power failure in the battery circuit, appropriate indication and activation of the APS FLT and ALARM technical outputs takes place. 8.1. Battery detection.
www.pulsar.pl EN54-7A28LCD RED POWER The battery test will also be automatically locked when the PSU is in the operating mode, in which the battery test is impossible. Such condition occurs, for example, during battery assisted operation or when the power supply is overloaded. In this case, the LCD will display the crossed out „START” message in the PSU Settings -> PSU -> Battery test menu. Fig. 28. Battery test – inactive. 8.6. Measurement of the resistance of the battery circuit.
www.pulsar.pl EN54-7A28LCD RED POWER 9. Remote monitoring (options: Wi-Fi, Ethernet, RS485, USB). 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 Wi-Fi, Ethernet or RS485 standard. It is possible to connect the PSU and the computer via the USB –TTL interface.
www.pulsar.pl EN54-7A28LCD RED POWER The RS485-ETHERNET „INTRE” interface is a device used to convert signals between the RS485 bus and the Ethernet network.
