HUMAN-MACHINE INTERFACE
GENERAL
This section describes the BE1-CDS220 Current Differential System optional human-machine interface
(HMI) and illustrates the front panel display menu tree branches.
FRONT PANEL DISPLAY
Figure 10-1 shows the standard front panel HMI for a horizontal mount BE1-CDS220 Current Differential
System. The vertical mount relay layout has identical functionality. The locators and descriptions of Table
10-1 correspond to the locators shown in figure 10-1.

Locator Description
A
Identification Label – This label lists the style number, serial number, sensing input current
and voltage range, and power supply input voltages.
B Power Indicator – This green LED lights when operating power is applied to the relay.
C
Relay Trouble Indicator – This red LED lights momentarily during start-up and lights
continuously when a relay failure is detected. Section 6, Reporting and Alarm Functions,
provides a complete description of all relay failure alarm diagnostics.
D, E
Minor Alarm, Major Alarm Indicators – These red LEDs light to indicate that a programmable
alarm has been set. Each indicator can be programmed to annunciate one or more
conditions. Section 6, Reporting and Alarm Functions, provides detailed information about
programming alarms.
F
Trip Indicator – A flashing Trip LED indicates that a protective element is picked up. A
continuously lit LED indicates that a trip output is closed. This red LED is sealed in if a
protective trip has occurred and targets are displayed.
G
Communication Port 0 – This RS-232 serial port can be used to communicate with the relay
using simple ASCII command language. A computer terminal or PC running terminal
emulation software (such as Windows

HyperTerminal) is required to send commands to
the relay or receive information from the relay.
