BE1-CDS220 Quick Start 2-3
For example, the 51N element has two modes (disabled and enabled), and one input, block (torque
control). To use this element, the logic setting command might be SL-51N=1,/IN2 for Set Logic-51N to be
Mode 1 (enabled) with the element blocked when contact sensing Input 2 is not (/) energized. Contact
Sensing Input 2 would be wired to a ground relay enable switch.
As noted before, the protection settings for this element, pickup, time dial, and curve, must be set
separately in the setting group settings. The setting might be S0-51N=6.5,2.1,S1R for Set in Setting
Group 0 - the 51N function = to pickup at 6.5 amps with a time dial of 2.1 using curve S1 with an
integrating reset characteristic.
The 51N element has two logic output variables, 51NT (Trip) and 51NPU (Picked Up). The combination of
the logic settings and the operational settings for the element govern how these variables respond to logic
and current inputs.
Output Logic Settings
BESTlogic, as implemented in the BE1-CDS220, supports up to 16 output expressions. The output
expressions are called virtual outputs to distinguish them from the physical output relays. In the BE1-
CDS220, VOA and VO1 through VO6 drive physical outputs OUT A (fail safe alarm output), and OUT1
through OUT6 respectively. The rest of the virtual outputs can be used for intermediate logic expressions.
For example, OUT1 is wired to the trip bus of a circuit breaker. To set up the logic to trip the breaker, the
BESTlogic setting command might be SL-VO1=VO11+101T+BFPU for Set Logic - Virtual Output 1 = to
Virtual Output 11 (which is the intermediate logic expression for all of the element tripping outputs) or (+)
101T (the trip output of the virtual breaker control switch) or (+) BFPU (the pickup output of the breaker
failure element that indicates that breaker failure has been initiated). To assign this to OUT1, the
BESTlogic command would be SL-OUT1=VO1.
USER INTERFACES
Three user interfaces are provided for interacting with the BE1-CDS220 relay: the front panel HMI, ASCII
communications, and the BESTCOMS for BE1-CDS220 software. The front panel HMI provides access to
a subset of the total functionality of the device. ASCII communications provides access to all settings,
controls, reports, and metering functionality of the system. The BESTCOMS for BE1-CDS220 software
provides a Windows based, user-friendly environment for editing settings files and uploading and
downloading them from the relay (see Section 14 for details).
Front Panel HMI
The front panel HMI consists of five LEDs for indicating power supply status, relay trouble alarm status,
programmable major and minor alarm status, and a multipurpose Trip LED that flashes to indicate that a
protective element is picked up. The Trip LED lights continuously when the trip output is energized and
seals in when a protective trip has occurred.
There is an optional front panel HMI that has all of the above features plus a two line by a 16 character
LCD (liquid crystal display) with four scrolling pushbuttons, an edit pushbutton, and a reset pushbutton.
The EDIT pushbutton includes an LED to indicate when edit mode is active. When the Trip LED lights
solidly, it indicates that target information is being displayed on the LCD. Specify front panel option “Y”
when ordering to receive the optional front panel. A complete description of the HMI is included in Section
10, Human-Machine Interface.
The BE1-CDS220 HMI is menu driven and organized into a menu tree structure with six branches. A
complete menu tree description with displays is also provided in Section 10, Human-Machine Interface. A
list of the menu branches and a brief description for scrolling through the menu is in the following
paragraphs.
1. REPORT STATUS. Display and resetting of general status information such as targets, alarms,
recloser status, etc.
2. CONTROL. Operation of manual controls such as virtual switches, selection of active setting
group, etc.
3. METERING. Display of real time metering values.
4. REPORTS. Display and resetting of report information such as time and date, demand registers,
breaker duty statistics, etc.
5. PROTECTION. Display and setting of protective function setting parameters such as logic
scheme, pickups, time delays, etc.
