FX70 Supervisory Controller Installation Instructions

Removing and Replacing the Cover
You must remove the controller’s cover to connect the
battery (new unit), and/or to install any option cards, or
replace the NiMH battery. The cover snaps onto the
base with four plastic end tabs—two on each end.
Note:
If accessory modules are plugged into the
controller, you may need to slide them away from the
unit to get to the end cover tabs.
•
To remove the cover, press in the tabs on both
ends of the unit, and carefully lift it off (see the
Important statement in this section). If necessary,
unplug the LED cable from the cover, at the
connector on the back of the cover (see Figure 4).
•
To replace the cover, make sure that the LED cable
is connected and not folded outside the base.
Orient the cover so the cutout area for comm ports
is correct, then push inwards to snap in place.
Board Layout
Figure 6 shows the location of connectors, option slots,
and other features of the main board in the FX70. For
side views of communications ports and other features,
see Figure 8.
The FX70 ships with both option card slots 1 and 2
open. The Double Data Rate 2 Random Access
Memory (DDR-2 RAM) socket is populated with a
1 GB module. A variety of communications option
cards are available.
IMPORTANT:
A Light-Emitting Diode (LED) ribbon
cable connects the cover to the main board. Be
careful when lifting the cover off. If the controller is
on a flat work surface, you can leave the cable
connected, with the cover next to the unit. See
Figure 5.
