Ultramax PB Supplementary Information For AGU2.511
Communication Clip Installation Including LMU64 Controller
reprogramming. (Part Code. 96.38000-7005)
Following the installation of the AGU2.5 communication clip (complete with base mounted wiring
connection) onto the front of the LMU64 controller a number of operational parameters within the unit
must be altered to ensure the clips operates as required.
LMU64 Pictured above with AGU2.511 and OCI420 communication clips.
A number of parameters will require altering within the LMU64 controller from their standard default
setting to allow the AGU2.511 communication clip to operate correctly.
Access is gained to the H parameters by pressing the PROG ! buttons simultaneously for 3 seconds
unit H 90 appears on the screen. The required H parameters can then be reached by using the PROG
. Or PROG !buttons. Once at the required H parameter the required setting is achieved by using the
+ - buttons. To save the alteration in the controller the INFO button must be pressed.
