FX Supervisory Controller Installation Instructions 17
Connecting the Backup Battery
With the cover removed from the FX20/FX60, locate
the red and black wires with a plug on the backup
battery. Insert the plug into the battery connector on
the bottom board as shown in Figure 10.

The connector is keyed so you cannot insert it
incorrectly. The red (positive) connection should be the
furthest from the two 30-pin option board connectors.
For more battery details, see About the Battery.
Operation
Apply power to the FX20/FX60 by plugging in the
power plug into either the FX20 (if using the wall
mount power module) or the 24 VAC/DC power
module. If the controller is using the line voltage power
module, energize the 90-263 VAC circuit.
IMPORTANT: Do not connect both the wall power
module and the DIN rail power modules at the same
time, or equipment damage will result, or a power
outage may go unrecognized.
Checking the Status LEDs
When power is applied, the green LED labeled Status
is lit. This indicates that the system is normal and
power is applied. Once the FX20/FX60 boots, the
yellow BEAT (heartbeat) LED begins to blink, with a
typical rate of about one blink per second. Blinking
should begin within 30 seconds after power is applied.
If, after applying power, the STATUS LED goes out, or
the BEAT LED comes on steady and stays lit for
longer than 2 minutes, contact your technical support
representative for assistance. See also Using Status
LEDs.
About the Battery
The FX20/FX60 is provided with a custom, 10-cell
NiMH battery pack mounted to the unit under the
cover. This battery allows the FX Supervisory to
continue operation through very short power
interruptions (a few seconds in duration). If a longer
power outage occurs, the battery provides enough run
time for the FX Supervisory to backup data and then
shutdown. Typically, this takes 1 minute to complete.
Shutdown occurs automatically, after data is backed
up to onboard flash memory.
The FX20/FX60 charges the battery during normal
operation, until fully charged. Typically, the charge
operation completes within 18 hours. Following a
power outage, the battery is charged again, as
necessary. The power and battery circuitry is
monitored by a station running on the FX20/FX60 (via
the PowerMonitorService). Station alarms are
generated when primary power is lost, or if the battery
is uncharged or unable to hold a sufficient charge.
The battery should be replaced about every 3 years. If
the unit is in a high temperature environment, replace
it more often.
Note: The NiMH battery looses its charge if not left
in trickle-charge mode. If you leave the battery
disconnected or attached to the unit when powered off,
the battery fully discharges in a matter of weeks. A
new FX20/FX60 ships from the factory with a
completely discharged battery; after installation, allow
at least 18 hours for the battery to fully charge.
Using Status LEDs
The FX20/FX60 includes several LEDs that can help
determine the status of the unit. These LEDs include:
Ethernet Ports
Heartbeat
Status
Serial Ports
Refer to Figure 6 for the location of the status LEDs.
Ethernet Ports LEDs
Each Ethernet port has one green LED, visible on the
top cover. A LAN# LED indicates activity on that port
as follows:
Off: No Ethernet link is established.
On: Ethernet link is established, but no activity is
on the LAN.
Blinking: Ethernet link is established with data
activity on the LAN.
