Resistance Temperature Detector (49RTD)
Fourteen resistance temperature detector elements provide over/undertemperature protection in
applications where a remote RTD module is connected to the BE1-11m via Ethernet or RS-485 cable. For
more information, refer to the
RTD Module chapter.
Incomplete Sequence (48) Protection
An incomplete sequence element protects the motor from damage by announcing an incomplete
sequence if the motor starts and does not reach the running state after the user-settable time delay
expires.
Starts per Time Interval (66) Protection
A starts per time interval element prevents the motor from starting if the user-defined number of starts is
exceeded within a user-defined time interval.
Restart Inhibit Protection
A restart inhibit element prevents the motor from being started when motor or system conditions are such
that a motor start would not be successful due to thermal limits, or motor starting is not desired for
process or system reasons.
Analog Input Protection
Eight analog input protection elements monitor external analog input signals when two remote RTD
modules are connected via an Ethernet or RS-485 cable. Four analog inputs are provided with each RTD
module. For more information, refer to the
RTD Module chapter.
Fuse Loss (60FL)
A fuse loss element protects against false tripping due to a loss of voltage sensing. Voltage transformer
circuit monitoring adds security by detecting problems in the voltage transformer sensing circuits and
preventing mis-operations of the 27P, 47, 59P, and 51/27 functions.
Breaker Control Switch (101)
Tripping and closing of a selected breaker can be controlled by the virtual breaker control switch. The
virtual breaker control switch is accessed locally at the front panel or remotely through the communication
ports.
Virtual Control Switches (43)
Five virtual control switches are accessed locally at the front panel or remotely through the
communication ports. Virtual switches can be used to trip and close additional switches or breakers, or
enable and disable certain functions.
Logic Timers (62)
Eight logic timers with six modes of operation emulate virtually any type of timer.
Lockout Functions (86)
Two lockout elements are provided.
BESTlogic
™Plus Programmable Logic
Each BE1-11m protection and control function is implemented in an independent function element. Every
function block is equivalent to its single function, discrete device counterpart so it is immediately familiar
to the protection engineer. Each independent function block has all of the inputs and outputs that the
discrete component counterpart may have. Programming with BESTlogicPlus is equivalent to choosing
the devices required by your protection and control scheme and then drawing schematic diagrams to
connect the inputs and outputs to obtain the desired operating logic.
