BE1-BPR Functional Description
Figure 4-1. Functional Block Diagram
Serial Ports RS-232/RS-485
Serial communication ports at the front and rear of the BPR relay provide total programming capability and
remote access for diagnostic, relay setup, and control.
Circuit Operation
The microprocessor continually monitors itself to ensure proper operation. Separate, independent circuitry
monitors the power supply and the microprocessor to ensure that any problem in these areas automatically
takes the BPR Relay off-line and activates the alarm output. Relay circuit functions illustrated in Figure 4-1
are described in the following paragraphs.
Power Supply
The isolated switching power supply generates ±12 Vdc, +5 Vdc, and an is5 Vdc. If the +5 Vdc
digital supply falls outside the defined tolerance, then the microprocessor will be reset by the power supply
supervisory circuit. This reset takes the relay off-line and lights the ALARM LED.
