I/O Wiring
The FX22/FX62 has 16 on-board I/O points that
include:
•Eight Universal Inputs that support analog inputs
(temperature, resistance , voltage, a nd current) an d
digital inputs (contact closure, pulse count).
•Eight Outputs that include:
•four analog outputs (0–10 VDC)
•four relay digital outputs (24 VAC/VDC, 0.5 A
maximum)
See Figure 12 for location of I/O terminals.
Inputs
Each of the eight Universal Inputs (UIs) can support
•Type-3 10k ohm Thermistor (also see the Important
Figure 13: Thermistor Sensor Wiring
Figure 14: 0–10 VDC Sensor Wiring
Figure 15: 4 to 20 mA Sensor Wiring
statement for Resistive 0—100k Ohms
)
•Resistive 0–100k ohms
•0–10 VDC
•4–20 mA
•Binary Input (BI) (Contacts or Pulse)
Thermistor
Inputs support 10k Thermistor temperature sensors.
Input accuracy is ±1% of span. By default, conversion
is for a standard Type 3 thermistor sensor, with a
sensor range of -10 to 135°F (23.3 to 57.2°C). Use a
conversion type of Tabular Thermistor to specify a
different thermistor response curve, by importing a
thermistor curve .xml file. Currently, the kitIo module
contains an xml folder with thermistor curves for
various thermistor temperature sensors. You can also
edit and export (for reuse) customized thermistor curve
xml files. Refer to the Niagara
AX
NRIO Guide for details
(in the docs folder in FX Workbench).
Figure 13 shows the wiring diagram for a Thermistor
sensor.
0–10 VDC
Inputs support self-powered 0–10 VDC sensors. Input
impedance is greater than 5k ohms. 0–10 V accuracy
is ±2% of span, without user calibration. Figure 14
shows the wiring diagram for a 0–10 VDC sensor.
4–20 mA
Inputs support self-powered or supervisory
controller-powered 4–20 mA sensors. The input
requires an external 499-ohm resistor for current input
(four resistors are supplied). For supervisory
controller-powered sensors, the supervisory
controller’s two V+ terminals supply 24 VDC, at up to
80 mA combined. Input accuracy is ±2% of span,
without user calibration.
Resistive 0—100k Ohms
Inputs can read a resistive signal within a ra nge fro m 0
to 100,000 ohms. Wiring is the same as shown for a
Thermistor temperature sensor (Figure 13). Resistive
signals require a ResistiveInputPoint.
IMPORTANT: UI inputs provide optimum
resistive-to-temperature resolution in the 10k ohm
range. For a sensor with a range far from 10k ohms
(such as a 100-ohm or 1000-ohm sensor), reso lution
is unusable. To successfully use such a sensor,
install a transmitter that produces a VDC or mA
signal, and then wire the transmitter to the UI
according to the 0–10 VDC or 4–20 mA instructions.
Figure 15 shows wiring used for a 4–20 mA
self-powered sensor (top) and a 2-wire supervisory
controller-powered sensor (bottom).
Note: A 4–20 mA sensor requires a
Vo ltageInputPoint, using conversion type 500 Ohm
Shunt, and secondary conversion type Linear.
Inputs support both pulse contacts and normal dry
(equipment status) contacts.
•Pulse contacts may have a Change of State
(COS) frequency of up to 20 Hz with a 50% duty
cycle.
Note: Minimum dwell time must be > 25 ms.
(Contacts must remain open at least 25 ms and be
closed at least 25 ms.)
•Standard Dry cont a ct s must have a 1 Hz (or less)
COS frequency, with minimum dwell time > 500
ms. (Contacts must remain open at least 500 ms
and be closed at least 500 ms.)
Note: Both types of dry contacts support 3.3 VDC
open circuits or 330 µA short circuit current.
Figure 16 shows the wiring diagram for binary input
wiring.
•For a pulse contact, use the CounterInputPoint in
the station database.
•For other dry contacts, use the
BooleanInputPoint.
Analog Outputs
Analog Outputs (AOs) are referenced by the terminals
labeled An and GND (ground). Each AO can supply a
maximum of 4 mA over the entire 0 to 10 VDC range.
The minimum input impedance of a device controlled
by an AO must be greater than 2,500 ohms. Ty pical
wiring for an AO is shown in Figure 17.
For each AO, use VoltageOutputWritable in the
station database.
Relay Outputs
Each relay output is rated at 24 VAC or VDC at 0.5 A.
Relay outputs have Metal Oxide Varistor (MOV)
suppressors to support inductive type loads such as
heavy duty relay coils.
Outputs
The FX22/FX62 has four 0–10 V Analog Outputs and
four digital Relay Outputs. See Figure 12 for location of
the output terminals.

normal operation, an On status indicates that the load
is powered. See About LEDs

details.
Nrio16Module (Software) Representation
In the station interface to the LP-FX22xx and LPFX62xx, the FX22/FX62 supervisory controller’s
onboard I/O is modeled in the stat ion’s M2mIoNetwork
(copied from the nrio palette), under a child
Nrio16Module device level component. This
Nrio16Module has a default name of LocalIo16.
If there are no remote I/O modules (LP-FXRIO16-0),
this is the only Nrio network needed in the station.
The M2mIoNetwork has a fixed Port Name property of
COM3, and a Trunk property of 1.
If any remote I/O modules are connected to the
FX22/FX62 RS-485 port, the station needs an
additional NrioNetwork, with a Port Name property of
COM2, and Trunk property of 2. For more details, refer
to the Niagara
Workbench). For wiring details, see Wiring to Remote I/O Modules on page 19. Note that a maximum of three
LP-FXRIO16-0 modules is recommended, due to
platform resource considerations.
AX
NRIO Guide (in the docs folder in FX
After remote I/O modules are discovered and added to
the station under this separate NrioNetwork (each one
as an Nrio16Module), the serial status LEDs for the
supervisory controller’s RS-485 port (S2TX, S2RX)
continually flash, reflecting polling activity. See About LEDs on page 21 for more details. Also, the STATUS
LED on each remote I/O module lights solid green.
Note: Any time a remote I/O module’s status LED is
not lit solid green, all of its outputs are in failsafe state
(all relay outputs OFF, and all AOs are at a 0-volt level).
Blinking of a remote I/O module’s status LED occurs for
two reasons, shown at different rates:
•Rapid flash (low duty cycle), meaning the unit is
unconfigured. Discovery and addition to the station
database is required.
•Equal time on and off (50% duty cycle), meaning
the unit is configured, but currently offline with the
FX22/FX62. Check RS-485 wiring between the
controller and remote I/O module.
For both local and remote I/O, each input or output
used requires a special Niagara Remote Input/Output
(Nrio) point to be added in the station database. These
components act as the station interface to the physical
I/O points. The Nrio points you need for each input or
output type are noted in previous wiring se ctio ns in
boldface.
For Nrio software details, see the Niagara
AX
NRIO
Guide in Workbench online Help, or the PDF in the
docs folder in FX Workbench.
Communications Wiring
Communications ports on the supervisory controllers
are on the edge of the supervisory controller board,
accessible with the right cover removed (Figure 19).
Communications port types include:
•Ethernet
•Serial
Note: Prior to connecting cables, provide strain relief
to prevent damage to the supervisory controller.
Ethernet
Two female 10/100 mega bits per second (Mbps)
Ethernet connections are provided on the supervisory
controller. These Ethernet connections are RJ-45
connectors labeled PRI and SEC. Use a standard
Ethernet patch cable for connecting to a hub or
Ethernet switch.
The supervisory controller’s factory default Internet
Protocol (IP) address for PRI (LAN1) is 192.168.1.149,
and the subnet mask is 255.255.255.0.
By default, SEC (LAN2) on the supervisory controller is
Figure 19: Communications Wiring
(Right Side Cover Removed)
disabled.
IMPORTANT: Typica lly, you only use PRI (primary
port), unless you have a specific application for
isolating a driver’s network traffic to a separate LAN,
using SEC. Do not use SEC as the primary port.
Serial
There are two RS serial ports on the FX22/FX62 base
board. Each has a UART capable of operation up to
115,200 baud.
•An RS-232 port uses an RJ-45 socket connector,
and operates as COM1.
•An isolated RS-485 port is on three terminals of a
6-position screw-terminal connector, and operates
as COM2 (by default).
Note: An additional serial port may be added with an
option card in Option Slot 1, such as an LP-FXRS232-0
card (port operates as COM7) or LP-FXRS485-0. This
option adds two serial ports, which operate in the
supervisory controller as COM7 and COM8.
Note: If a dialup modem option card (LP-FXMDM-0) is
installed in the FX22/FX62, the onbo ard RS-232 por t is
disabled, and the modem operates as COM1. This
option card is not supported if the FX22/FX62 is
equipped with the onboard GPRS modem.
RS-232
You can make RS-232 serial port connections to the
female (socket) RJ-45 connectors using an
8-conductor flat silver satin stranded cable with
standard male (plug) RJ-45 connectors. Connect the
flat satin cable (maximum distance 50 ft [15.24 m])
through the enclosure knockout nearest the port. This
straight-through cable is then connected to a
socket-to-socket type RJ-45-to-DB-9 adapter.
The supervisory controller is a serial Data Terminal
Equipment (DTE) device; another DTE device (a
computer, for example) requires a null modem adapter
(LP-KITFX2DB-0, optional item). If connecting the
supervisory controller to a Data Circuit Terminating
Equipment (DCE) device (a modem, for example), you
can use a straight through adapter. Table 4 provides
pinouts for both types of RJ-45 to DB-9 adapters.
Note: Silver satin cable is not standard Ethernet
Unshielded Twisted Pair (UTP) cable, in which the
pairs are twisted around each other. The twisting of the
pairs may cause undesirable effects on serial
communications; therefore, we recommend the use of
flat silver satin cable instead. Flat silver satin cable is
unshielded. If installing flat silver satin cable in a noisy
electrical environment, run the cable through conduit.
Note: If you need a temporary serial shell connection
from your computer to the supervisory controller, and
you have the necessary RJ-45 to DB-9 null modem
adapter (LP-KITFX2DB-0), but you have no silver satin
cable, you can substitute an ordinary Ethernet patch
cable. However, using silver satin cable is
recommended for any permanent RS-232 connection.
Note: If the supervisory controller reboots with the
mode jumper in the Serial Shell position (see
Figure 10), the RS-232 port provides system shell
access. If a dialup modem option card (LP-FXMDM-0)
is installed, this modem is disabled during this serial
shell access. LP-FXMDM-0 operation resumes on ly
after putting the mode jumper back to the Normal
position, and then rebooting the supervisory controller.

RS-485
An RS-485, optically isolated port is available on three
pins of a 6-position connector, and operates by default
as COM2. As shown in Figure 19, the screw terminals
are minus (–), plus (+), and shield. Wire in a continuous
multidrop fashion to other RS-485 devices, meaning
minus-to-minus, plus-to-plus, and shield-to-shield.
Connect the shield-to-earth ground at one end only,
such as at the FX22/FX62 Supervisory Controller. For
wiring to one or more remote I/O modules
(LP-FXRIO16-0), see Wiring to Remote I/O Modules
The FX22/FX62 Supervisory Controller provides a
2-position connector for support of an external 12 V
Sealed Lead Acid (SLA) rechargable battery. Usage is
optional. For more details, see
Battery Backup
on page 21.
Wiring to Remote I/O Modules
Wiring to remote I/O modules (LP-FXRIO16-0) typically
provides both 15 VDC power and 12 V battery backup
to the modules, along with RS-485 communications
(Figure 21).

Powerup and Initial Checkout
Complete all mounting and wiring procedures (I/O
Wiring, Communications Wiring, External 12 V Backup
Battery, Wiring to Remote I/O Modules), then perform
the following:
•Apply power.
•Check status LEDs.
Note: Also see About the Backup Batteries
20.
Apply Power
CAUTION: Risk of Property Damage.
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.
Mise En Garde: Risque de dégâts
matériels. Ne pas mettre le système
sous tension avant d'avoir vérifié tous les
raccords de câblage. Des fils formant un
court-circuit ou connectés de façon
incorrecte risquent d'endommager
irrémédiablement l'équipement.
IMPORTANT: The FX22/FX62 Supervisory
Controllers do not include an on/off switch. To apply
power, energize the 24 V AC transformer (or 24 VDC
power supply) wired to its 3-position power input
terminals.
If remote I/O modules are wired to the unit, they are
also typically powered by the controller as well.
Check the Status LEDs
See Figure 22 for a description of the status LEDs.
When power is applied, the green STATUS LED lights
(top LED). The STATUS LED indicates that the system
is OK and that power is applied. Once the supervisory
controller boots, the yellow BEAT (heartbeat) LED
begins a steady blink, with a typical rate of about once
per second (1 Hz). The BEAT LED begins blinking
within 30 seconds after power is applied.

About the Backup Batteries
The FX22/FX62 can have two different backup
batteries:
For continuous system operation during loss of primary
AC power (unless power is lost for only a few seco nds),
both backup batteries should be installed. Station
alarms are generated if either battery is uncharged or
unable to hold a sufficient charge, as well as wh enever
primary power is lost. Always investigate any alarm
related to backup batteries.
NiMH Battery Pack
Note: See the NiMH Battery Precautions
A custom 10-cell NiMH battery pack is mounted inside
the FX22/FX62, under the cover, on top of a metal
shield plate (see Figure 2). This battery allows the
supervisory controller to continue station operation
(only) through very short power interruptions (a few
seconds in duration). If a longer outage occurs, the
NiMH battery provides enough run time for the
supervisory controller to backup data, and then
shutdown. T ypically, this process takes about 1 minute.
Shutdown occurs automatically, after data is backed up
to the onboard flash memory.
Upon startup (boot), a test of the NiMH battery is
performed. A system alarm is generated if the NiMH
battery voltage level is found to be bad. A charge is
also initiated upon startup, which last s from 3 hours
minimum, and up to 18 hours if the battery is
completely discharged.
During this NiMH battery charge period, neither the
NiMH battery or the external backup battery (if
installed) is tested. After the startup NiMH charge
period, a periodic test occurs of the NiMH battery (and
the backup battery, if the supervisory controller
platform is so configured). The appropriate battery
alarm is generated if either battery is found to be bad.
Note: If the last NiMH battery test was bad, upon loss
of primary power, the FX22/FX62 performs an
immediate shutdown, backing up data and powe ring off
(including attached expansion modules).
Note: A NiMH battery characteristic is to lose charge if
Figure 22: FX22/FX62 LED Descriptions
not left in charge mode (trickle charge). Leaving the
battery unconnected, or in the unit powered off causes
the battery to fully discharge in a matter of weeks. Note
that in the case of a new FX22/FX62, it ships from the
factory with a completely discharged battery.
Therefore, allow at least 18 hours for the battery to
charge if it has not been in a powered unit.
Replace the NiMH battery pack every three years, or
more often if the supervisory controller is in a high
temperature environment. For more information on the
use and replacement of the battery, refer to Required NiMH Battery Maintenance on page 22.
Battery Backup
The optional sealed lead acid backup battery is an
external, 12 V, rechargeable battery (or multiple
batteries) sized to operate the system during loss of
primary power for an extended duration of time. The
backup battery includes power to the FX22/FX62, as
well as any attached remote I/O expansion modules.
Connect the backup battery to the supervisory
controller using a 2-position connector (Figure 20).
Whenever primary powered, the supervisory controller
supplies a constant trickle charge to this battery, at
200 mA, maximum.
Note: Commonly used 12 V batteries for this
application include 7 Ampere hour rechargeable (7Ah r)
types, such as the Yuasa NP7-12 or Panasonic®
LC-R127R2P1, or equivalents.
Providing the FX22/FX62 platform is so configured, at
startup (boot), a test of the backup battery is
performed, as well as a periodic test. (The periodic test
is always performed. The startup test is selectable.) A
system alarm is generated if a battery test finds the
backup battery is bad. If the backup battery has a
successful test, upon loss of primary power, the system
operates from this backup battery power until the
charge level of the onboard NiMH battery pack reaches
0. Note that both batteries discharge in parallel;
however, as the sealed lead acid backup battery
capacity is much greater, the NiMH battery p ack
discharges much slower than if these backup batteries
were bad or not present.
Note: If the backup battery test was bad, upon loss of
primary power, the FX22/FX62 performs an immediate
shutdown, back up data and power off (including
attached readers, expansion mod ules).
Replace the sealed lead acid backup batteries
approximately every 3 years, or more often if the
supervisory controller is in a high temperature
environment.
About LEDs
The FX22/FX62 has a variety of LEDs, most of which
are visible on the left cover . Figure 22 provides the LED
locations and descriptions.
Status
The green STATUS LED is located on the cover. The
status LED remains lit when the supervisory controller
is powered, and blinks during the boot sequence. If the
status LED does not light while power is applied,
contact your technical support representative for
assistance.
Beat
The yellow heartbeat BEAT LED is located on the
cover. Following bootup, the heartbeat LED blinks
about once per second. If the heartbeat LED stays on
constantly , d oes not light, or blinks very fast (more than
once per second), contact your technical support
representative for assistance.
Ethernet
A green activity LED for each of the two Local Area
Network (LAN) ports (PRImary for LAN1, SECondary
for LAN2) is located on the cover under the STATUS
and BEAT LEDs, and operate as follows.
•Off—No Ethernet link is made
•On—Ethernet link is made, but no data activity on
the LAN
•Blinking—Ethernet link is made with data activity
on the LAN
Relay Out
Each of the four relay outputs has an associated gre en
LED on the cover , K4 to K1 (from top to bottom). Under
normal operation, each digital status LED indicates
activity as follows:
The GPRS LED provides status of the onboard GPRS
modem (for supervisory controller models so
equipped), and is visible on the cover . It flashe s various
LED patterns based on the state of the modem. This
LED is directly under control of the modem itself, not
the Niagara
Upon initial powerup, the GPRS LED pattern is typically
600 ms On/600 ms Off, and ma y change dep ending on
various modem state changes. If the supervisory
controller does not have the integral GPRS modem,
this LED remains Off without activity.

software.
Serial
LEDs for the two serial ports are located on the
supervisory controller’s main board, near the Analog
Output terminals (Figure 22). Board markings S1 and
S2 correspond to the software configuration of the
COM1 and COM2 ports. LEDs show the transmit (TX)
and receive (RX) activity for the two serial ports.
Remove the right cover to see the serial port LEDs.
See Removing and Replacing the Covers
•The yellow TX (transmit) LED indicates that the
supervisory controller is sending data out the serial
port over a communications line to a connected
device.
•The green RX (receive) LED indicates that the
supervisory controller is receiving data from a
connected device.
These LEDs are on only when data is detected on the
port. If the receive LED is on constantly, this indicates a
problem with the communications channel, such as a
shorted wire or reversed wiring.
Note: If the RS-485 port is connected to configured
remote I/O modules (LP-FXRIO16-0), during no rmal
operation the COM2 LEDs both continuously flash
about three times a second, indicating ongoing polling.

Required NiMH Battery Maintenance
NiMH Battery Precautions
See NiMH Battery Precautions
Battery life expectancy depends on its discharge cycles
(the number of discharges and their depth) and the
ambient temperature of the battery during normal
operation. In most applications, the NiMH battery
should see few discharges. Therefore, ambient
temperature determines the life expectancy of the
battery more than other factors. If the supervisory
controller is installed in a conditioned space, this
battery should provide dependable service for
approximately 3 years (average). In an environment
where the operating temperature is higher (> 50°C
[122°F]), the battery lasts approximately 1 year.
The NiMH battery in the supervisory controller is fully
discharged when factory shipped. Additionally, NiMH
batteries lose charge over time if not kept
trickle-charged (see NiMH Battery Pack
Therefore, even a new supervisory controller (or
replacement battery) requires up to 18 hours of
powered operation before the battery can provide
reliable backup power (before the battery is at full
charge).
The supervisory controller monitors the NiMH battery
and periodically loads the battery to test its ability to
maintain battery backed functions. Investigate any
battery trouble message, and check the battery
connections to the supervisory controller. Replace the
battery as required. To order a new battery, see
Standard Replacement Parts
