2. Spare:
An open slot(s) for installation of another function module.
3. Power Line Carrier Analog Module (optional):
The Power Line Carrier Analog Module is part of a module set which includes a Digital
PLC Module that plugs into the front of the chassis. The digital board has eight LEDs
and five test points on its front edge for service use only. The PLC Analog Module has
two BNC connectors for connection to the power line interface, a six pin terminal block
for connecting a CLI meter or second power supply. There are also fine and coarse
tuning controls and various variable resistors used to control the amplifier.
See Section 5 for a complete description of the PLC function.
4. System I/O Module:
The function of the System I/O Module is to provide the physical connection point
between the GARD Pro™ and the substation network. In addition to this, the System
I/O Module provides the following three timing functions:
Optional GPS
IRIG-B
1PPS (1 pulse per second timing signal)
An Optional GPS interface module (GPS time receiver) can be installed in the System
I/O Module. When it is installed, a GPS antenna must be connected to the SMA series
connector labeled “GPS” at the rear of the System I/O Module. When the GPS option is
installed, the BNC connectors labeled “IRIG-B’ and “1PPS” function as outputs and can
be used to drive equipment external to the GARD Pro™. In this case the IRIG-B output
is un-modulated.
When the GPS built-in receiver is included, it resides as a piggy-back module on the
System I/O Module. The GPS receiver has to be connected to an externally mounted
antenna, provided as an accessory as shown below.
Figure 2-6. GPS Antenna
Also located on the System I/O Module is a six pin (RS-485) terminal block for use with
the DNP protocol. The six pin connector is always installed, but only used when DNP
is enabled over RS-485. The Ethernet port is used for remote management purposes.
An RS-232 port is also available for management.

2.7 Controller Redundancy
2.7.1 Redundancy Controller Overview
The GARD Pro™ Controller Module offers a redundant operation mode when used in a 6U
chassis. When equipped with two Controller Modules, a GARD system can disable a faulty
module and transfer its functionality to the standby unit.
The redundant-mode control elements are effectively independent of basic GARD functions and
features. Redundancy subsystems monitor the condition of the module and take part in
determining which module is active.
When only a single Controller is present in a GARD chassis, the redundancy subsystem still
continues monitoring, however, it has no effect on the active state of the Controller. A single
module cannot be made inactive.
Warning: System Firmware version 2.1.0 or greater is required for Redundancy. Both
controllers must have matching system firmware versions for correct operation.
2.7.2 Rules Of Operation
Two GARD Controllers present in the chassis in their dedicated slots facilitate the redundant
mode of operation. Only 6U chassis offer two controller slots. Redundant mode is not possible
with a 3U chassis.
When Both Controller slots are in use, Slot 11 has priority, while Slot 10 the standby
(Redundant) Controller has a short delay allowing the Main controller to become active first.
An “ACTIVE” module drives or controls the traffic within the chassis and configures other
submodules. An “INACTIVE” module does not output any signals onto mid-plane buses.
The basic rules governing swapping between the active and inactive state were designed to be
as simple as possible and to minimize disturbances to the system and prevent swapping into a
faulty or non-existent module.
•
A module cannot decide by itself to become active. It can become active only if the
other Controller fails or is disabled.
•
A failed module does not necessary become inactive. A swap to the other module may
happen only if the other module exists and is itself not in fault. A system with
Redundancy will block a swap into a faulty module.
•
There are no levels or degrees of fault conditions within a Controller module. A faulty,
disabled or non-existent module is treated the same way, since its state is not
trustworthy anymore.
GARD Pro
December 1, 2016

Hubbell Power Systems, Inc. – RFL® Products
(c)2017 Hubbell Incorporated
•
An inactive Controller module always obtains its configuration for the chassis from the
active module – immediately after power-up and with continuing updates thereafter.
2.7.3 Implementation
Each GARD Controller contains a monitoring system, which monitors vital hardware signals
within the module. The CPU and DSP Processors monitor their own operations and interfaces.
A dedicated communications channel (“mirroring”) is used to transfer system information, such
as configuration, from the currently active to the inactive module. This allows a newly installed
(and inactive) controller to become configured and ready to take over control if required.
Dedicated signaling channels on the midplane are used to convey faults and activity states of
the Controllers to their companion modules.
The active module has full control of the system, just as if it was the only one present. The
inactive module is idling in full operational condition. All drivers of its signals to the backplane,
Ethernet, etc. are disabled.
Besides the Controller, no “slave” module (channel module or functional module) in the GARD
chassis is aware of the presence of two Controllers, nor does it know which one is active. The
system operates the same way, regardless of which Controller is active.
If an out-of-bounds condition is detected within a Controller, an on-board fault condition is set.
Based on the rules of redundant operation, the active and inactive states may be swapped
between the two Controllers.
A Controller swap will affect GARD functionality momentarily while the “Inactive” controller
becomes “Active” and takes over control. Critical functionality will be restored within 1
minute, after the swap occurs.

2.7.4 Controls and Indicators
LED Indicator
LED indicator DS3, located at the card edge of the module, shows the state of redundancy
control of a Controller Module.
Mode Switch
A request to take the Controller module off-line (inactive) is made by moving card-edge switch
SW2 from “Normal” position to “Disable” position. This is equivalent to creating an on-board
failure, and will be indicated by the appropriate color of indicator DS3 (color will change from
Green to Orange).
If the rules of redundant-mode operation are satisfied, the Controller will become inactive and
the other module will take over.
It is important to remember that even though the Controller will be in a failed state, it may be
actually made inactive only if a good companion module exists.
The rules of operation are designed to enforce the continuity of operation for the whole system.
Therefore, a module cannot be made inactive if the other Controller is in a fault condition or
does not exist.
Returning SW2 to the “Normal” position will clear the on-board fault condition. It does not
automatically make the module active. As per the rules of operation, the Controller Module
becomes active only if the other module fails or is disabled.
Configuration Mirroring
An inactive Controller module will retrieve (mirror) a copy of a system configuration from the
active module. This process starts immediately after power-up or reset of the Controller and
continues as long as the module remains inactive.
When manually forcing a switch between redundant controllers (such as when installing a new
module from a set of spares), the user should observe whether the first configuration transfer
completed, as indicated by DS3. If switched too early, the newly active Controller may be
configured incorrectly.
After first successful mirror, the inactive Controller will contain a copy of configuration that is
no more than one mirroring cycle behind the active module.

cabinet at the customer's site. In such cases, the entire assembly is enclosed in a wood crate or
delivered by air-ride van:
1.
If the equipment is crated, carefully open the crate to avoid damaging the equipment.
2.
Remove the equipment from the crate and carefully examine all packing materials to
make sure no items of value are discarded.
3.
Make sure all modules are fully seated in the chassis. The machine screws securing all
I/O modules to the rear of the chassis should be fully tightened.
3.3 Mounting
After unpacking, GARD Pro™ equipment must be securely mounted, following the instructions
in the following paragraphs. Procedures are provided for individual chassis, interconnected
chassis installed in racks or cabinets, and interconnected chassis mounted on shipping rails; use
the procedure that suits your equipment.
3.3.1 Individual Chassis

3.3.2 Interconnected Chassis Installed in Rack or Cabinet
Systems mounted in racks or cabinets at the factory are to be placed in position and then bolted
to the floor or wall, as appropriate, to secure the equipment in place. The type of hardware used
will depend upon the particular surface to which the rack or cabinet is being mounted. Because
of this, mounting hardware is not supplied with the rack or cabinet.
3.3.3 Interconnected Chassis Mounted on Shipping Rails
Equipment to be installed in a rack or cabinet at the customer's site is mounted on shipping rails
at the factory. To remove the shipping rails and mount the equipment, proceed as follows:
1.
Place the equipment as close to the front of the rack or cabinet as possible, with the rear
panels of the equipment facing the front of the rack or cabinet.
2.
Remove all the screws securing the shipping rails to the equipment.
3.
Slide the equipment into the rack or cabinet.
4.
Install and tighten screws to all panels to secure the equipment in place.
3.4 Ventilation
The specified operating temperature range for GARD Pro™ equipment is -20oC to +70oC
(-4oF to +158oF). Operation at higher temperatures may affect system reliability and
performance. Systems installed in enclosed cabinets should be ventilated to keep the
temperature inside the cabinet within limits.
CAUTION
During normal system operation, the switching of relay contacts can produce
voltage spikes; these spikes can travel down the relay output leads and induce
currents in other leads. These induced currents can result in false trips. To reduce
this possibility, use a shielded twisted pair for each input lead, and ground the shield
at the GARD PRO™ chassis only. As an added precaution, do not bundle input,
output, and power leads into the same harness, and keep them as far apart as
possible.

WARNING!
The GARD Pro™ must be properly grounded as described in the following section before
attempting to connect input power. Improper ground connections may result in system
malfunctions, equipment damage, or electric shock.
3.6.3 Chassis Ground Connections
A protective earth stud at the lower right rear of the GARD Pro™ chassis is the main ground
for the terminal.

Hubbell Power Systems, Inc. – RFL® Products
(c)2017 Hubbell Incorporated
Grounding is accomplished by connecting a wire 6AWG or larger between this protective earth
stud and rack ground. The grounding wire should be kept as short and straight as possible, to
keep its resistance and inductance to a minimum.
Before attempting to make power connections, make sure the GARD Pro™ terminal is
equipped with a power supply designed to operate at the available input supply voltage. This
can be determined by checking the power supply label on the exterior of the unit, as shown in
Figure 1-2 If an external power supply is being used, check the markings on the external power
supply. If the wrong voltage is connected to the power supply, component damage will result.
3.6.4 Input Power Connections
WARNING!
Individual double pole disconnects must be installed between the building or station battery
supply and GARD Pro™ power supply. This must be done for both the main and back-up
supply.
CAUTION
Power supplies are not hot swappable. Power must be switched off at the appropriate power
supply, before installing or removing power supplies from the GARD Pro™ chassis
After all other connections have been made to the GARD Pro™, input power connections can be
made to the Power Supply I/O at the rear of the chassis.
Before proceeding to connect power to the GARD Pro™ ensure that the main and redundant power
switches on the rear of the unit are in the “OFF” position and that the power wires to be installed are
disconnected at their source.
If only one power supply is installed at the front of the chassis in the slot designated as “Power
Supply 1”, input power connections must be made to the terminal block labeled “Power Supply
1” at the rear of the chassis. If only one power supply is installed at the front of the chassis in
the slot designated as “Power Supply 2”, input power connections must be made to the terminal
block labeled “Power Supply 2” at the rear of the chassis. If two power supplies are installed at
the front of the chassis, input power connections must be made to the terminal blocks labeled
“Power Supply 1” and “Power Supply 2” at the rear of the chassis.
Input power connections can be either DC station battery voltage (24, 48, or 250VDC) or AC
voltage (125VAC or 220VAC), depending on which power supplies are installed in the chassis.
Station battery positive goes to the “+” terminal and station battery negative goes to the “-“
terminal. If AC input power is used, connections are made to the “+” and “-” terminals and the
polarity markings can be neglected.

Before connecting the power at its source and switching on the GARD Pro™, check the following:
•
Is the GARD Pro™ grounded correctly?
•
Is the installed GARD Pro™ power supply designed to operate at the available input
supply voltage?
•
Is the polarity of the supply power correct?
•
If installed in an enclosed cabinet, is the unit ventilated correctly?
Power connections may now be made to the GARD Pro™.
3.7 Current Limiter Option
The current limit module is used with the station battery to supply and limit the current through
older carrier auxiliary relays (such as KA-4 relays). This module is located on the inside of the
chassis. On the 3U chassis it is located on the left hand side of the frame when viewed from the
rear, next to the I/O System Module. On the 6U chassis it is located below the Power Supply
Board on the right hand frame when viewed from the rear. For terminal block designations see
the diagram below.

3.8 GARD Pro™ Boot-Up Sequence
When the LEDs on the front panel display (see Figure 2-7) are lit the unit has booted up. This
should take less than 2 minutes. However for a more detailed description of the boot-up
process, proceed as follows.
With the front panel open, verify that a boot up is in progress as displayed by the LEDs (DS1DS4) on the Controller Module.
a. During the multiple stages of the boot-up process the DS1 and DS2 indicators will
change colors (starting red, yellow and green). A Solid Green LED of DS1 indicates a
final boot up has been successfully completed.

b. The complete boot-up process will take less than 2 minutes.
c. The LED DS2 indicates the status of the Front and Rear Ethernet Port. When the LED
is unlit, the Ethernet cable is not connected to the Front or Rear RJ-45 Ports. If the LED
is orange the Ethernet cable is connected to the Front Port, if the LED is Green the
connection is made to the Rear Port.
d. The LED DS3 indicates a state of redundancy control. (The 3U chassis does not support
redundancy, therefore this LED under a normal condition should be solid green).
However, if this LED is Solid Orange the module has detected an on-board fault, but it
continues operating. If the LED DS3 is Red the module has detected an on-board fault
and is not functioning.
e. The LED DS4 indicates logic error or failure.
f. Verify the position of the Toggle Switch SW2. In the 3U chassis, SW2 should be in the
NORM position (left-front view) and not in the Disable position.
g. After a successful boot up the GARD Pro™ is ready for interrogation through the front
or rear Ethernet Port.

4.1 Connecting a Laptop and Setting IP Addresses
The GARD Pro™ is delivered with pre-set IP addresses. The front port IP address is fixed, and
factory set to 192.168.1.1 with a subnet mask of 255.255.255.0. The rear port IP address is
configurable.
4.1.1 Front Ethernet Port
The IP Address assigned to the front port is https://192.168.1.1 for every GARD Pro™ chassis.
DO NOT plug this port into a LAN. You cannot have more than one device with the same
address on a network. The front port is strictly for direct connection to a Laptop PC. The
Laptop should have an IP Address on the same subnet (192.168.1.x) as described below. The
front port has no default gateway configured, so it is not routable. This is done for security
purposes

Note
All GARD Pro™ front Ethernet ports are preconfigured to an IP address of 192.168.1.1
at the factory, and cannot be changed.
Connect a standard Ethernet Cable from the RJ-45 Ethernet port on your PC to the front
RJ-45 Ethernet port on the GARD Pro™ as shown above.
DHCP (Dynamic Host Configuration Protocol) is available when connecting to the front
Ethernet port on the GARD Pro™ with a laptop or PC. DHCP will obtain the parameters
necessary for operation in an IP Network. This protocol greatly reduces the system
administration workload, allowing addressing setup with minimal or no manual configuration.

Pro™ front Ethernet port. This will be disabled by default, and is disabled after every
power-cycle or reboot of the GARD Pro™ controller module regardless of the setting.
Enabling the SCP server will only last until the controller reboots. Before a field
upgrade is possible the SCP server must be enabled, it will be disabled during the
upgrade process since power cycling is required.
2. HTTP/HTTPS: The GARD Pro™ web server can be configured to use either hypertext
transfer protocol (HTTP) by itself or https over a secure sockets layer (HTTPS), HTTP
is the default. When using HTTP without a secure sockets layer the entire web page and
form content is sent in clear text. Passwords and usernames are obscured to prevent the
casual user from seeing them in packet captures, but this is by no means secure. When
using https all traffic between the browser and server is encrypted.
The server on the GARD Pro™ may be configured to listen to HTTP requests on the
front port, HTTPS requests, both or none for front and rear Ethernet ports
independently. The option to listen to none or turn off the server is available only for
the rear port. The front port must be configured for at least one protocol.
3. HTTPS Certificate/Key Pair: In order to perform the security tasks involved the
GARD Pro™ needs a certificate file and private key file, both of which must be PEM
(Privately Enhanced Mail) encoded. The unit comes with an RFL self-signed
certificate. You may choose between using the built in certificate and key or a custom
certificate and key that you upload.

Power Line Carrier
Section 5. P ow er Line Carrier
5.1 Power Line Carrier Function
The RFL GARD Pro™ with PLC is a Single Function PLC protection unit. The PLC function
consists of two plug-in modules: A digital module which plugs into the front of the chassis, and
an Analog module which plugs into the rear of the chassis. Both modules can be installed in a
3U or 6U GARD Pro™ chassis.
The single function channel can be configured for two modes of operation: FSK, or On/Off. In
FSK mode, it can be configured to support either 2F or 3F operation. In On/Off mode, it can be
configured to support both Normal Checkback and Hard Carrier Checkback.
In addition to performing the normal PLC functions, the unit will monitor the transmit interface
to measure transmit power, reflected power, trans-hybrid loss, and receive signal strength.
5.1.1 FSK Operation
As stated above the GARD Pro™ with PLC supports two FSK operational modes: 2F and 3F.
In 2F operation a guard tone is located at a fixed deviation below or above the channel center
frequency. At the occurrence of a trip, the tone shifts to the opposite side of the channel center
frequency. In 3F operation a guard tone is located at the channel center frequency. One of two
trips can occur. One trip causes the tone to shift a fixed deviation below the channel center
frequency. The other trip causes the tone to shift a fixed deviation above the channel center
frequency.
The performance of 2F and 3F operation is defined by the Maximum Trip Transport Delay,
Dependability and Security.
Maximum Trip Transport Delay is defined as the time between the following two events: 1)
when the unit transmitter is notified of a trip event through the Logic Bus, until 2) the unit
receiver on the other side of the link writes the trip event into the Logic Bus status registers.
More specifically, it is defined as the delay between the Logic Bus frame reception interrupt
which contains the trip event information until the status register is written in the receiver. The
Maximum Trip Transport Delay for 2F operation is defined by the three operational
configurations given in Table 5-1. The Maximum Trip Transport Delay for 3F operation is
defined by the three operational configurations given in Table 5-2. See also Figure 5-1.
Minimum Channel Spacing (FSK).
Dependability is defined as the probability that a trip event will be successfully communicated
to the other end of the link within the Maximum Trip Transport Delay as a function of the
signal to noise ratio of the link.
Security is defined as the probability that a false trip event will be declared at the receive end of
the link as a function of the signal to noise ratio of the link.

5.1.2 On/Off Operation
On-Off operation defines the absence of a tone (Off) to be the guard condition. The presence of
a tone (On) is the block condition. Since there is no tone present under normal non-block
operating conditions, no receive AGC functions may be performed. Therefore, the nominal
receive signal level is determined during deployment, and the operating parameters of the
system are set accordingly and maintained in non-volatile memory of the Module.
In order to determine that the link is operating normally, a checkback process is used to test the
link. For the purposes of checkback, the Module at the near end of the link is defined as the
Master and the Module at the far end of the link is defined as the Remote. During checkback, a
pre-defined sequence of on-off states (checkback codes) is transmitted by the Master to the
Remote which responds with an acknowledgement on a successful reception.
The Remote responds in one of two ways depending on how the Master terminates its
transmission of the Checkback Code. If the Master leaves the tone on for 5 seconds after the
last bit of the Checkback Code, the Remote responds in Hard Carrier Mode. Otherwise, the
Remote responds in Normal Mode. In Normal Mode, the Remote responds by transmitting a
pre-defined sequence of on-off states (called the Acknowledgement Code) to the Master. In
Hard Carrier Mode, the Remote responds by transmitting a tone to the Master for a pre-defined
length of time.
Four, Hard carrier transmitted codes and two received codes can be programmed into either the
master or remote units. Operation from either end is possible.
Checkback may be initiated automatically by either the Master or the Remote. It may also be
initiated manually by the user. Remote initiation is accomplished by sending a specific code to
the master. This code tells the master to initiate a test sequence. This code is not available as a
response code from remotes for normal tests.
On/Off Systems transmit and receive on the same frequency. Therefore, the local receiver
cannot differentiate between remote transmissions and local transmissions. In addition,
checkback sequences are detected as a sequence of block events. The local receiver will report
all block events through the Logic Bus interface whether the source is from local transmissions,
checkback sequences, or real block events. It is up to the logging mechanism in the Logic
Controller to filter out unwanted SOE reports. To aid in this filtering the module will indicate
that a test is in process through a bit on the logic bus that is active while a test is ongoing in a
master or while an incoming code is detected in a remote.
The performance of On/Off operation is defined by the Maximum Block Transport Delay,
Dependability and Security.

Maximum Block Transport Delay is defined as the time between when the Module transmitter
is notified of a block event through the Logic Bus until the Module receiver on the other side of
the link writes the block event into the Logic Bus status registers. More specifically, it is
defined as the delay between the Logic Bus frame reception interrupt which contains the block
event information until the status register is written in the receiver. The Maximum Block
Transport Delay for On/Off operation is defined by the three operational configurations given
in the table below.
Dependability is defined as the probability that a block event will be successfully
communicated to the other end of the link within the Maximum Block Transport Delay as a
function of the signal to noise ratio of the link.
Security is defined as the probability that a false block event will be declared at the receive end
of the link as a function of the signal to noise ratio of the link.
Security & Dependability do not really apply to an on/off unit. The unit should issue a block
received output any time there is sufficient energy in the receive band regardless of total SNR.
Instead of security, adjacent channel rejection is probably more relevant. Dependability of an
on/off unit should remain constant as noise increases until the input circuits (or DSP numbers)
saturate.

5.1.3 Compatibility Issues for PLC Module Software
For users of older GARD Systems:
The PLC Module Software is used with the GARD Custom System Logic to meet each user’s
specific application needs. The PLC Module Logic and GARD PLC System Logic were
updated and both logic versions need to agree.
Beginning in October 2011, new PLC software (indicated as V17) was released to improve the
functionality of the unit. Although these changes are transparent to the end user, certain
compatibility issues with the new PLC software and older System Logic should be noted.
Units shipped after October 2011 will have updated default PLC System Logic, however if
GARD units are modified in the field and have either new PLC software with old PLC System
Logic or the reverse, the units may not perform as expected. The two scenarios are described
below:

Hubbell Power Systems, Inc. – RFL® Products
(c)2017 Hubbell Incorporated
Power Line Carrier
New PLC software/Old system logic
New System Logic/Old PLC software
The function to disable the Transmitter from an external input will not function.
The security against unwanted
operations in FSK mode will be slightly
reduced.
The unblocking feature in FSK will not work.
The RX SNR alarm will not work.
Because of these differences, care must be taken when swapping modules or reusing the
“Whole Chassis Configuration” files from different versions.
The following is invalid:
• Transferring existing PLC Digital Modules with V13 software (or earlier) into
units with updated System PLC Logic (V17 software).
• Transferring new PLC Digital Modules (V17 software) into existing units with
previous System PLC Logic revision, other than V17.
• Loading any whole chassis configuration files not identified as V17 (-A17-) into
units with new V17 PLC Digital Modules.
• Loading whole chassis configuration files with the new revision into units with
existing PLC Digital Modules (version V13 or earlier).
Identifying revision levels:
PLC Module software and System Logic:
Through the web interface, System Management > Inventory and Version Info
The revision of a System Logic or Whole Chassis Configuration file can be determined by its
file name. See the example below, taking note of the “17” identification after the revision
letter.
• Logic Filename: GARD3U175_00146_001_A17.EDN,.TXT,.DSN.PDF
• Whole Chassis Configuration Filename:
GARD3U175_00146_001_A17_C01.ZIP
When creating new Whole Chassis Configuration Files verify the version of the logic loaded
into the unit. If the unit has V17 System Logic installed then mark the filename with a V17
indication. This file should only be loaded into units with V17 PLC Module software.
RFL will modify any logic designed for the previous PLC software version (V13) and earlier
PLC software to work with version 17. Please do not hesitate to contact RFL for technical
support at 973-334-3100 ext 226 or via e-mail at [email protected]

CAUTION
The GARD Pro™ PLC Module set is a Static Sensitive Device. Persons working on this
equipment must observe Electro Static Discharge (ESD) precautions. As a minimum you must
do the following:
Use anti-static devices such as wrist straps and floor mats and leave modules in their anti-static
bags until they are ready to be installed.
Before proceeding to make connections to the Analog PLC Module ensure that all the modules
in the chassis are correctly seated. Remove the front panel to the GARD Pro™ chassis and
using minimal force remove and re-seat all front panel modules. Typically when a single PLC
module set is used they are installed in a 3U chassis, however if more than one PLC is required

Figure 5-6. CLI Meter, Front Panel Mounting on a 3U Chassis
The PLC carrier level indicator RX value is displayed on the meter. The value displayed
represents a variance in received signal level from the initial signal level when the unit was
commissioned. The meter is normally factory installed and MUST be used in conjunction with
the Digital PLC Module (500455-1). The meter is connected to J6 on the Digital PLC Board.
There are two potentiometers for Offset and Scale. Normally no adjustments are necessary as
the CLI Meter is calibrated before leaving the factory, but if tuning is required instructions are
given in Section 5.5.5.1.

useful in troubleshooting, tuning auxiliary coupling equipment or measuring levels etc. Forcing
the carrier will cause the PLC module to go into minor alarm. This reminds the user that the
PLC is not in its “normal” state. Remember to always put the carrier back into the normal
state before leaving the unit.

Receiver:
7. RX Block Frequency: Sets the RX block frequency from 30kHz to 500kHz in
0.125kHz increments.
8. RX Bandwidth: There are three settings available in On-Off mode: 500, 1000 or
1500Hz.
9. Block Hold Timer: This setting delays the dropout of the block output after the
blocking signal is lost. This delay can be set in the range of 0 to 50ms in increments of
1ms. The recommended default setting is 10ms. The timer increases the reliability of
the blocking receiver by preventing an intermittent loss of carrier. This loss can be
caused by arc gap flashover which would allow the protective relay to over-trip for an
external fault condition.
Start/Stop Logic:
10. Start Logic: Sets the polarity for the “Stop 1” and “Stop 2” input contacts. Can be set
to Normal or Inverted. When set to Normal, the contact is active when the station
battery voltage is present, and is inactive when the station battery voltage is not
present. When set to Inverted, the contact is inactive when the station battery voltage is
present, and is active when the station battery voltage is not present.
11. Start Logic – Start 1 or Start 2: Selects whether the “Start 1” and “Start 2” contacts
are ANDed or ORed. The options are “And” or “Or.”
12. Stop Logic: Sets the polarity for the “Start 1” and “Start 2” input contacts. Can be set
to Normal or Inverted. When set to Normal, the contact is active when the station
battery voltage is present, and is inactive when the station battery voltage is not
present. When set to Inverted, the contact is inactive when the station battery voltage is
present, and is active when the station battery voltage is not present.
13. Stop Logic – Stop 1 or Stop 2: Selects whether the “Stop 1” and “Stop 2” contacts are
ANDed or ORed. The options are “And” or “Or.”

5.5 Power Line Carrier Commissioning
5.5.1 Introduction
The GARD Pro™ with PLC is factory-configured as a 50-ohm power line carrier terminal. If
50-ohm termination is being used, then the Receiver Calibration is typically the only
commissioning procedure required in the field. This section is broken down into two parts: User
interface calibrations, which require a PC connected to the management port of the GARD
Pro™ PLC and rear module adjustments, which are made on the amplifier module.
Below is a complete list of calibrations and adjustment procedures:
User-interface calibrations:
•
•
•
Receive level calibration (user interface, field calibration procedure)
Transmit power level measurement calibration(user interface, factory-set at 50-ohm)
Reflected power measurement calibration (user interface, factory-set at 50-ohm)
Rear-module adjustments:
•
•
•
•
Impedance adjustment (rear module, factory-set at 50-ohm)
Transmit power level adjustment (rear module, factory-set at 50-ohm)
Transmit fail level adjustment (rear module, factory-set at 28.5dBm, 50-ohm)
Skewed hybrid tuning (rear module, factory-set at 50-ohm)
The following pages will describe calibration procedures initiated through the user interface:
WARNING!
When running the TX Monitor or Reflected Power Monitor level procedures the transmitter
MUST be terminated into a 50Ω non-inductive dummy load.

5.5.2 Calibrations through the User Interface
Menu location: Test > Calibrate.
The following example web page is for FSK applications. ON-OFF applications are similar but
not shown. As shown below, clicking on the listed calibration procedure will display the
required steps to complete the procedure. Note that the “Receiver Auto-Set” procedure should
be performed in the field. Follow the step-for-step calibration procedures as required.
This procedure should be
performed in the field
These procedures are factory set

5.5.2.1 Receiver Calibration
Receive Auto-Set: This procedure is the most commonly run calibration procedure and is
typically the only one that needs to be done in the field. This procedure will set up the PLC unit
for optimum performance on a particular PLC channel. The procedure is run after all channel
elements (traps, tuners, hybrids, etc.) have been installed and tuned. Once the channel has been
optimized, this procedure will calibrate the PLC for the nominal carrier receive level (0 dB),
setting up operation of things like front-panel CLI meter, Rx alarms, etc. It should only be done
at commissioning or any time there is a change made to the PLC system which affects the
carrier receive level.
5.5.2.2 TX Level Measurement
Set TX Monitor Level: This procedure calibrates the “TX Power Level” indication on the
Status page and as reported over DNP. This is a factory-calibration procedure, and is performed
at the factory using a 50-ohm load. This procedure is typically not done in the field, as it is
factory-set for 50-ohm applications.
5.5.2.3 Reflected Power Measurement Calibration
Set Reflected Power Monitor Level: This procedure calibrates the “Reflected Power Level”
indication on the Status page and as reported over DNP. This is a factory-calibration procedure,
and is performed at the factory using a 50-ohm load. This procedure is typically not done in the
field, as it is factory-set for 50-ohm applications.

5.5.3 Rear Module Adjustments
5.5.3.1 Equipment Requirements
The following equipment is required to perform the commissioning procedure:
•
Frequency-selective voltmeter (FSVM). Signalcrafters, PowerComm, etc.
•
Small Flat-head screwdriver (pot tweaker)
•
50-ohm load or dummy load (minimum 10W rating)
Adjustments are made to the PLC Analog Module rear panel as shown below.

5.5.3.2 Verifying/Adjusting Amplifier Output Impedance
The GARD Pro™ PLC amplifier output impedance is factory-set for 50-ohm impedance. This
procedure describes the fine adjustments that may need to be made in the field, in order to
precisely match impedance and minimize the reflected power.
When the load and source impedance are precisely matched, the loaded output voltage is
exactly one-half of the unloaded output voltage (or, the loaded output is 6dB below the
unloaded output). This fact is used to fine-tune the output impedance of the PLC amplifier.
Proceed with the following steps.
1. Send a “Guard” signal (FSK) or “Block” (On-Off) at 1W.
Note: Set block level to 1W (On-Off), otherwise send 1W Guard (FSK)
2. Disconnect the load from the amplifier.

3. Measure the transmit output level using an FSVM across the “PA-OUT” (red and
black) test points on the power amplifier module and record the value.
4. Re-connect the load, continuing to measure the transmit output level.
5. Adjust the potentiometer R13 on the rear of the amplifier module to achieve 50% of
the previously measured voltage, (or to achieve 6dB below the previously measured
level).
6. Complete. The PLC amplifier output impedance is now precisely matched to the
impedance
5.5.3.3 Verifying/Adjusting the Transmit Output Power
The PLC amplifier output power level is factory-set for +30dBm (1W) and +40dBm (10W) into
a 50-ohm impedance. This procedure describes how to verify the transmit output power, and
how to make adjustments (if required).
1. Connect the TX port of the PLC to a 50-ohm load.
2. Measure the transmit output level using an FSVM across the “PA-OUT” (red and
black) test points on the power amplifier module.
3. Key the transmitter at 10W using the keying inputs or the input test pages
(See 4.7.1.4)
4. Measure +40dBm (10W at 50-ohm) on the FSVM. If the reading is not +40dBm,
adjust the potentiometer R8 on the rear of the amplifier module to achieve +40dBm
(22.26Vrms).
5. Complete. The transmitter levels are now verified / adjusted for 1W and/or 10W.
5.5.3.4 Transmit Fail Adjustment
The PLC amplifier output transmit fail (“TX Fail”) level is factory-set for +28.5dBm into a 50ohm impedance. This is typically sufficient for most applications. The TX Fail alarm will go
active if the transmitter output fails below this level. If a different TX Fail level is desired, this
procedure describes how to verify/adjust the TX Fail level.
1. Connect the FSVM to the PA OUT Test Points on the Analog Module and tune the
FSVM for the TX frequency.
2. Send Guard (In FSK) or Block (On-Off) at 1W (30dBm).
3. Adjust R8 on the Power Amplifier until the desired TX Fail Threshold is shown on
the FSVM.
Note: RFL recommends setting the threshold to 1.5dB below the Guard or Block
Signal level (28.5dBm).
4. Adjust the TX Fail Threshold pot (R19) of the Power Amplifier until the TX Fail
Output turns on.
5. Adjust the Gain pot (R8) on the Power Amplifier until the nominal TX level is
shown on the FSVM.
6. Confirm TX Fail Output is OFF.

5.5.3.5 Hybrid Tuning Procedure (If Equipped)
The PLC internal skewed hybrid is factory-set for a 50-ohm impedance. So long as the
termination impedance is 50-ohm, no adjustment should be necessary. This procedure describes
how to verify the skewed hybrid operation, and how to make adjustments (if required). The
purpose of tuning the PLC internal skewed hybrid is to match the transmit impedance to the line
tuner impedance, in order to minimize reflected power. The skewed hybrid also provides
isolation between the TX and RX signals, while coupling the transmitter to the line with
minimal loss.
1. Install the amplifier module on a card extender (Part No.500940).
2. Verify that jumpers J12 through J15 do not have jumpers installed.

5.5.4 Setting the Transmit Carrier Frequency Range
The operating band transmit carrier frequency is normally factory set, however if changes are
required in the field the following settings may be followed.
The operating band of the PLC is from 30kHz to 500kHz. Jumpers J3 through J11 on the
Analog Module can be set to accomplish the desired frequency range. Note that the circuit
board has been revised with the addition of jumpers J38, J39 and J40. Table 6.1 gives the
assembly numbers for the new Analog Module Assembly with various operating options
followed by the jumper settings to achieve the required frequency range. Table 6.3 gives the
assembly numbers for the old board followed by the jumper settings to achieve the required
frequency range. Note that on the old board the 393.5kHz to 500kHz version has no
jumper settings.

5.5.5 Carrier Level Indicator Settings
The PLC has a carrier level indicator output for use with external measuring devices such as a
panel meter or an analog RTU input. The value at this output represents a variance in received
signal level from the initial signal level when the unit was commissioned. The output is an
analog value that is at mid-scale when the commissioned level is being received. It is above
mid-scale for higher levels and below mid-scale for lower levels.
The output is actually a voltage output with one of three jumper selectable resistors in series
with it. When attached to the proper load, the current swings over the designated range.
J34 J33 J32
Figure 5-25. PLC Analog Module, Carrier Level Indicator Modes - Jumpers
Install a jumper for the required setting as shown below and in the following table. When a
jumper is installed the other two jumpers must be empty (uninstalled). Note that the CLI output
levels are calibrated during the receiver commissioning procedure and no further adjustments
are necessary or possible.
The three jumper settings are as follows:
•
The “0-5V” jumper position (J32) puts a 5K ohm resistor in the circuit. When
connected to a high impedance volt meter the resistor is insignificant and the output is
2.5 volts at mid-scale. The scale is 0.25V/dB and the resolution is 1dB. This means that
a signal 6dB higher than commissioned level will result in an output of 4.00 volts.
Similarly, a drop of 6dB will result in an output of 1.00 volts. The maximum scale is
+/- 10dB or 5.00V to 0V.
•
The “0-1 mA” jumper position (J34) is designed for panel meters with an input load
of 5k Ohms. The full scale output of 5V through 5Kohms will result in 1mA. There is a
50 ohm resistor in the output circuit to protect against short circuits. The scale will
effectively be 0.05mA/dB.
•
The “0-100 µA” jumper position (J33) is designed for low impedance current sensors.
Full scale will result in 5V/50Kohms or 100µA. The scale will effectively be 5µA/dB.

The DIP switches shown above are factory set to protect the circuit board from overvoltage or
excessive phase angle situations. See Table 5-6 for a description of the switch settings.
If the protective circuits are activated the Power Amplifier will shut down for approximately
2.5 seconds and then come up for 25ms. This pattern will continue until the safety parameters
are met and the condition cleared.

The function of the TX Filter is to filter out harmonics and noise that is out of the bandwidth of
the filter. The bandwidth of the filter can be set to either 8kHz or 16kHz using two
programmable jumpers, J1 and J45. The filter center frequency is tunable from 24kHz to
496kHz using programmable jumpers. The outer edges are 20kHz and 500kHz. The 8kHz
bandwidth is used for most applications.
5.6.3.1 Setting Jumpers on the TX Filter
The TX Filter consists of two PC boards that are mounted at right angles to each other and are
supported by an aluminum frame. The TX Filter has a total of 44 jumpers that must be
configured for proper system operation. Two of these jumpers (J1 and J45) are used to select
the bandwidth of the filter which can be either 8kHz or 16kHz. Jumper J44 is used for system
testing, and the other 41 jumpers are used to tune the center frequency of the filter from 24kHz
to 496kHz. The outer edges are 20kHz and 500kHz. Tuning the filter is done from the 9508 TX
Filter Programming Sheet supplied by RFL on the Customer CD. 27 of the jumpers are located
on the 107828-2 board. This is the board with the two large air core inductors shown on the

5.6.5.1.1 Hybrid Transformers
The RFL 9508 Line Board contains two hybrid transformers, T3 and T4. The primary winding
of T3 accepts the transmit input signal, and the primary winding of T4 develops the receive
output signal that is passed to the RX Filter.
Both hybrid transformers have two secondary windings, and are interconnected so that one
secondary of T3 is in series with a secondary of T4. One set of secondaries is connected across
the complex balance network, and the other set of secondaries is connected to the line coupling
equipment through line matching transformer T2. Fuses F1 and F2 provide overcurrent
protection, and surge arrestors E1 and E2, protect the equipment against an overvoltage
condition. For four wire applications, the signal going to the line coupling equipment can be
monitored at TP2, and the signal coming from the line coupling equipment can be monitored at
TP3. For two wire applications the signal going to or coming from the line coupling equipment
can be monitored at TP2.
5.6.5.1.2 Receive Attenuator
Resistors R9, R11, R12 and dual-section Receive Level potentiometer R10 are connected across
the primary of T4 to form an attenuator. The amount of signal sent to the RX Filter is controlled
by the setting of R10. Zener diodes CR1 and CR2 clamp the signal to a safe level. The signal
being sent to the RX Filter can be monitored at test points TP6 and TP7.
5.6.5.1.3 Complex Balance Network
Inductors L1 through L8, capacitors C1 through C9, Coarse Switch S1, fine potentiometer R1
and resistors R2 through R8 form an internal reactive balance network. This network is
connected across one set of secondaries of the hybrid transformers. Jumper J13 can be used to
enable or disable the internal balance network. The balance network is adjusted to match the
line impedance. To adjust the network, a frequency selective voltmeter (FSVM) is connected
across test points TP6 and TP7 on the Line Board, and S1 and R1 are adjusted to the lowest
possible transmitter signal level. S1 provides a rough adjustment of the resistance across the
hybrid secondaries by determining how many resistors in the network are connected in series.
R1 provides a fine resistance adjustment that allows the resistive balance to be precisely set.
Inductors L1 through L8 and capacitors C1 through C9 form the reactive portion of the balance
network. All components in the reactive portion can be jumpered in or out to balance out local
line reactance. L1 through L8 can be enabled or disabled by jumpers J13 through J19. Jumper
J1 controls C1, J2 controls C2, and so on. If no reactive balancing is required, J1 through J9,
and J14 through J19 must be placed in the out position.
5.6.5.1.4 Dummy Load
An internal Dummy Load and Attenuator Board are provided as described in Section 5.5.8 To
observe the signal going to the line coupling equipment use test points TP1 and TP2.
5.6.5.1.5 Impedance Matching Transformers
Impedance matching transformers T1 and T2 match the impedance of the Line Board to that of
the line. Jumper J10 selects one of T1’s four impedance settings: 50, 75, 100, or 130 ohms.
Fuse F1 provides current protection, and surge arrestor E2 protects the equipment against an
overvoltage condition. Jumper J20 selects one of T2’s four impedance settings: 50, 75, 100, or
130 ohms. Fuse F2 provides current protection, and surge arrestor E1 protects the equipment
against an overvoltage condition. In 2 wire applications, the signal going to or coming from the
GARD Pro

line coupling equipment can be monitored at test point TP2. In 4 wire applications, the signal
going to the line coupling equipment can be monitored at test point TP2, and the signal coming
from the line coupling equipment can be monitored at test point TP3.
5.6.5.2 Setting Jumpers and Controls on the Line Board
The Line Board has 25 jumpers that must be set for proper system operation. Two of these
jumpers, J10 and J20, are for impedance matching, 12 jumpers are used for balancing the line
impedance, and 4 jumpers are used to select 2W or 4W operation. The location of these jumpers
is shown below. Refer to Table 5-11 for information on how to configure these jumpers on the
Line Board.

In addition to the jumpers, the RX filter has three tunable inductors, L1, L2 and L3. Their
functions are as follows:
L2 controls the balance of the filter (flat response at both sides of center frequency).
L1 controls the attenuation at the upper side of center frequency.
L3 controls the attenuation at the lower side of center frequency.

*Note
At TB1-8 on the Mother Board Rear Panel a ground wire should be connected. Ideally this
wire should go directly to the sub-station ground bar, if this is not feasible, shorting the wire to
TB1-7 (Chassis ground) is an alternate method. This will cause surge currents to pass through
the Mother Board and chassis before exiting to ground. Connecting directly to the sub-station
ground bar is preferred.
5.6.10 Quick Tuning Procedure and Jumper Setting Overview
1.
For the selected center frequency, set the jumpers as described in the Microsoft Excel®
Worksheet “9508 Rx Filter Programming Sheet.xls.”
2.
Connect a signal generator (HP3336B or HP3325A or equivalent) to J2 of the Rx Filter.
Connect a selective level meter (Wandel & Golterman SPM-32A or 33A, Rycom
6021A, Signalcrafters 110, or equivalent) with a terminating impedance of 50 Ohms, to
J3 of the RX Filter. Use J4 as the ground connection.
3.
Set the center frequency of the test equipment (signal generator and selective level
meter) according to the selection made in Step 1.
4
Adjust inductors L1, L2 and L3 to have a minimum loss (highest voltage level) at the
selected center frequency.
For 8kHz bandwidth Rx Filters, perform steps 5, 6 and 7.
For 16kHz bandwidth Rx Filters perform steps 8, 9 and 10.
5.
Check the attenuation at the selected center frequency +/- 4kHz <0.35 dBm.
Adjust L2 to have a balanced response (the same level at +4 and –4 kHz) dBm.
6.
Check the attenuation at the selected center frequency +/- 12kHz.
Adjust L1 to get the desired attenuation at +12 kHz >9.5 dBm.
Adjust L3 to get the desired attenuation at +12 kHz >9.5 dBm.

5.7 Optional Switched Battery Power Supply
I/O Module, Single On-Off Switch
This module was developed for use when a PLC (On-Off) module is installed in a GARD Pro™
chassis. Input power is feed out to an auxiliary device through the Switched Battery Terminals
as shown below. No communication interface is possible with this Power Supply I/O when a
double pole switch is used.
This Power Supply I/O will connect internal power supplies to an external auxiliary device and
provide major and minor alarm contacts. The switch has a dual function when placed in the
OFF position:
a. Main power is disconnected.
b. Power is disconnected to an auxiliary device.

The “+” and “-”designations on the Power Supply I/O module rear panel terminals are totally
arbitrary and the AC or “+” and “-”DC external power sources can be connected to either
terminal. The major and minor alarm relays are contained on this interface and the connections
are brought out to the lower three terminals of each terminal block as shown in the figure
above. Both relays are energized under normal operating conditions and are de-energized for an
alarm or alert condition. This ensures that the chassis will cause an alarm condition when power
is lost.

6.3 Module Level Alarms
Each module can report a Major or Minor alarm. This information is sent over the Control Bus
and is a status condition only. The time critical alarms should be handled by the logic functions.
Not all modules generate alarms.
The criteria for a module going into Major or Minor alarm is hard-wired into the module and
cannot be changed by the user. However, how the system reacts to these alarms is controlled by
the user. For each alarm type on each module, the user can select if he wants to put the system
into Major Alarm, Minor Alarm, or to ignore the module alarm.
The user programs the GARD Pro™ alarms using the Alarm Configurations Webpage
described in Section 4.11.2
