Non-replaceable Parts
The controller contains a non-replaceable 2.5 A
slow-blow fuse, soldered on the main circuit board.
This fuse provides protection from internal shorts or
connection to incorrect power supplies. If the fuse
circuitry is suspect, contact technical support for
assistance.
Standard Replacement Parts
Table 5 lists the standard replacement parts. Standard
replacement parts cannot be returned for credit and
should be disposed of in an appropriate manner.
New Replacement Unit
To replace a faulty FX70, order a new one. To ensure
proper credit for a FX70 still under warranty, contact
the Johnson Controls Product Sales Operations Team
for return authorization.
Note:
Before ordering a new controller, it is strongly
recommended that you contact your normal technical
support resource to eliminate the possibility of a
software issue or mis-configuration problem.
Replacing the FX70 Supervisory Controller
To replace an FX70 with a new replacement unit,
proceed as follows:
1.
Use FX Workbench to back up the FX70
configuration to your computer.
2.
Remove power to the controller, including any
external 12 V battery. The unit should power down
automatically. Wait for all LEDs to remain off.
3.
Remove the front cover. See

Note positions of all communications and other
wiring cables going to the controller. If necessary,
label connectors and accessory modules to avoid
mis-connection later, after the controller is
replaced.
