Enable Jumper
The RTU uses battery-backed memory to store
setpoints and the current time and date. The
battery for the MultiFlex RTU is located either
underneath the output plug-in board (for old-
style MultiFlex boards) or on the rear side of the
input board layer facing the snap-track ( Figure
2-7 ).
Battery-backed memory is enabled by the
ENABLE BATTERY jumper (JP5) located at
the bottom right corner of the input board layer
(
Figure 2-8
). This jumper is shipped from
Emerson in the DISABLE position. The jumper
should be set to the ENABLE position (UP)
before installation. To preserve battery life,
when storing the MultiFlex RTU, the jumper
should be set to the DISABLE position.
