3.15.2.1 Configuring the Monitoring Through the EPS30-4815AF
The EPS30-4815AF system converts the input 220 VAC into the -48 VDC to provide the -48
VDC power. In addition, the EPS30-4815AF system can manage one VRLA battery set and
monitor other environment parameters through its EPMU03 monitoring module. This topic
provides the basic information about the EPS30-4815AF and describes how to configure data
associated with environment monitoring.
Prerequisites
l
The EPS30-4815AF must be connected to the ESC port of the control board on the
MA5616 through a straight-through cable.
l
The setting of the hardware DIP switch on the EPS30-4815AF must be the same as the
setting of the EMU subnode in the environment configuration.
l
The sixth DIP switch on the EPS30-4815AF must be set to off, which indicates that the
baud rate is 19200 bit/s.
Context
l
The differences between an analog parameter and a digital parameter are as follows:
–
An analog parameter is a consecutive parameter, such as the temperature, voltage, and
current.
–
A digital parameter is a discrete value that indicates a state.
l
The EPS30-4815AF requires an RS-485 serial port for data communication.
