Quick Start Guide — Allen-Bradley Bulletin 825-P Modular Protection System Saving Settings It is important to note that programmed values become operational only after they have been saved to memory. The programming system will prompt to save settings when the user navigates higher up in the programming menu by pressing the ESCape key. The front panel display is as follows: Save Changes? Yes No To save changes, place the cursor at “Yes” and press the Enter System Configuration key.

Quick Start Guide — Allen-Bradley Bulletin 825-P Modular Protection System ATTENTION Protection elements have no effect until they are assigned to the Trip relay or an auxiliary relay. ! To assign functions to the output relays and inputs, use the following path: MAIN > Set/Show > IO Assign TIP The relay outputs will function as a N.C. contacts when the relay behavior setting is Fail-Safe (Y), and will function as a N.O. contacts when the relay behavior setting is Non-FailSafe (N).
Quick Start Guide — Allen-Bradley Bulletin 825-P Modular Protection System Trip Relay Assign The 825-P allows mapping of only protection trip elements to the Trip output relay. Settings are presented as bit-enumerated strings. The second line of the display identifies a given bit’s associated function. To assign a function to the Trip relay, simply program a value “1” in the bit location for each element you desire to assign using the TRIP A through TRIP D settings.
Quick Start Guide — Allen-Bradley Bulletin 825-P Modular Protection System AUX# Assign The 825-P allows mapping of protection (trip and warning) and general-purpose control elements to the auxiliary outputs. Assign functions to the auxiliary relays in the same manner as performed with the Trip relay settings.
Quick Start Guide — Allen-Bradley Bulletin 825-P Modular Protection System IN# Assign The 825-P provides the ability to assign a control function to each discreet input. Table H shows the available control functions and the method of assigning them.
