Configuring Protection & Logic Functions
Overview
This chapter describes configuring the 825-P relay settings for motor protection,
basic functions, I/O mapping, and communications.
This chapter includes the following subsections:
• Application Data – information that is required about the protected
mo
tor before calculating the relay settings
• Main Settings – settings that configure the relay inputs to accurately
mea
sure and interpret the AC current and optional voltage input signals
• B
asic Motor Protection – settings for protection elements included in all
models of t
he 825-P, including the thermal element, overcurrent elements,
load-loss functions, and load-jam functions
• RTD-Based Protection – settings associated with the RTD inputs
(re
quires RTD Scanner Module)
• Voltage-Based Protection (Relays With Voltage Inputs) – settings
as
sociated with the optional AC voltage-based protection elements
• I/O Co
nfiguration – settings for the front-panel display control, control
in
puts/outputs, and analog output for all relay models
• Serial Port Settings – settings that configure the relay front and rear panel
ser
ial ports
• DeviceNet Port Settings – settings that configure the relay rear panel
De
viceNet port
• S
elect Relay Logic Diagrams – selected logic diagrams for protection,
con
trol, and outputs
NOTE: Each 825-P is shipped with default factory settings. Calculate the settings for your motor
