FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which standard relay functions are provided through Eaton 4A55149H02?
The LMR Plus Power I/O Board provides seven standard relay positions for Common Alarm, Phase Failure, Phase Reversal, Pump Run, Startup, Acceleration and Future 1 functions.
How can the relay-output capacity of Eaton 4A55149H02 be expanded?
The Power I/O Board accepts up to four snap-on optional relay boards. Each optional board provides two relays, allowing up to eight additional relay outputs.
What must be verified when connecting line-voltage sensing to Eaton 4A55149H02?
Verify the controller nameplate voltage, incoming conductors and applicable wiring diagram before connection. The three transformers used by the LMR Plus Power I/O Board support line-voltage sensing from 100 to 600 V AC.
Which controller documentation should be used with 4A55149H02?
Use the documentation and wiring drawings for the exact installed Eaton LMR Plus controller and starting method. Family information does not replace the unit schematic.
Where should field wiring be checked when replacing Eaton 4A55149H02?
Check the customer connection terminals located along the bottom of the Power I/O Board. Record every terminal number, conductor position and associated field function before disconnecting the original board.
How can relay commands be diagnosed on Eaton 4A55149H02?
Use the onboard LED assigned to each relay to confirm whether its coil is being commanded. A lit LED confirms the coil command only, so the relay contacts, terminal wiring and connected field circuit must also be tested.
Which optional I/O settings must be preserved when replacing Eaton 4A55149H02?
Record the custom input and output labels, relay links, alarm associations, fail-safe selections, latching behavior and programmed time delays. These settings must be restored before the fire-pump controller returns to service.
