B.11 Electrical Termination

Surge Protection Recommendations

This electric blower utilizes a number of processor-based control

systems, all of which are susceptible to damage from lightning and

other electrical surges. While every effort has been made to ensure

that the control systems have been adequately ‘hardened’, Thermon
Heating System’s surge mitigation efforts can only be effective if ALL

external remote circuits connecting to the electric blower have been

protected by primary surge protection devices in accordance with
the following generally accepted requirements for surge protection of
wayside signal equipment:

• Provide primary surge protection devices (standard

signal air gap arresters) on all external electric blower
control I/O circuits. These arresters should be located

“upstream” of the electric blower housing (within the

signal housing, which interfaces to the electric blower).
It is essential to protect ALL circuits entering or leaving
the signal housing.

• Provide a primary surge protection device

(commercial high capacity MOV type) on the
external electric blower AC power feed. This surge

protection device should be located “upstream” of
the electric blower in conjunction with the electrical
service entrance panel and main disconnect.
Observe primary surge protector manufacturer’s

instructions for installation and circuit breaker

protection (if required).

• Grounding of the electric blower metal housing as

well as the ground terminals of the primary arresters

is essential for personnel protection as well as surge

protection. Grounding rods and conductors must

be installed in accordance with the AREMA Signal
Manual of Recommended Practice.

• Primary surge protection must be installed in

accordance with the AREMA Signal Manual of

Recommended Practice.

3. Conductors are to be sized in accordance with the electrical

code and the minimum circuit ampacity data as detailed on the
unit’s data plate.

Thermon Heating Systems Inc.

4. Incoming supply lines should be connected directly to

the main disconnect switch. Where applicable the neutral
should be connected to the neutral lug and grounded at
the source.

See photo detail below for electrical connection points.

Electrical Connection Points

WARNING

WARNIN G

Electrical connections are to be performed by qualified
personnel and in accordance with the local electrical
code and the local electrical authority.

1. Connection entries for electrical conduits are located

on the right hand side of the discharge duct. The power
connection entry is 1 1/4" NPT and the remote signal entry
is 1/2" NPT.

2. The use of water tight connections for incoming conduits

is mandatory. See applicable electrical codes for seal
requirements of field installed conduits.

5. The control chassis and the rest of the main unit must be

connected to ground.

6. The maximum allowable deviation from rated voltage to

supply line voltage is 5%. Verify voltage is present on all
three lines for three phase units and two lines for single
phase units.

7. Customer requested external low voltage signal inputs and

outputs shall be routed through the secondary connection
point adjacent to the main power connection. Termination of
remote operator controls is found in Section D. Controls of
this manual under D.4 Remote Signalling.

8. Manually spin the blower shaft to ensure the blower turns freely.

9. The electric blower unit is electrically isolated from the track

by the isolation block between the distribution duct and the
flexible duct.

inrush of multiple units

• Staggered starting of motor and elements to minimize

peak current draw

• Self monitoring and automatic adjustment to minimize risk

of damage while maintaining a reduced but effective level
of snow clearing and sensing operation in the event of
some installation issues or equipment failures

D.2 Control System Operating Modes

1. Timed Local Run Mode: The Fastrax

if the “MANUAL START” button is pushed for 3 seconds

or one of the snow sensors detects snow. The Fastrax
will run in this mode until the red “MANUAL START” button

is released and the snow sensors no longer detect snow, at

which point it will begin a timed run where it will continue to

run in this mode until the preset run time (2 hours by default)
has elapsed. The run timer will be reset if the “MANUAL

START” button is pushed or one of the snow sensors
detects snow again.

2. Timed Remote Run Mode: The Fastrax

after the remote start/stop contacts are held closed while

“REMOTE TIMEOUT MODE” is on (default). The Fastra x

FEB will begin a timed run and will continue to run until the
preset run time has elapsed or the remote start/stop contacts
are opened.

NOTE: Opening of the remote start/stop contacts will cancel

the timed run if the snow sensors are not currently
detecting snow.

3. Continuous Remote Run Mode: The Fastrax

mode while the remote start/stop contacts are closed and

“REMOTE TIMEOUT MODE” is off. The Fastrax

run in “CONTINUOUS REMOTE RUN MODE” until the
remote start/stop contacts are opened.

4. Cooldown Mode: If “COLD AIR MODE” is off, the Fastrax

FEB enters “COOLDOWN MODE” after exiting the run

®

modes. The Fastrax

FEB will run in “COOLDOWN MODE”

where the duct heater is off and the blower continues to run
until the preset cooldown time (3 minutes) has elapsed or

®

the Fastrax

FEB is forced to re-enter a run mode.

5. Cold Air Mode: This mode increases energy efficiency

in exchange for reduced snow clearing capability. While

“COLD AIR MODE” is inactive (default), the Fastrax

discharges heated air while it is running. While “COLD AIR

MODE” is active, the Fastrax

it is running.

The Fastrax

®

FEB may be forced to enter this mode

regardless of the setting of the “COLD AIR MODE” selector
switch if the primary high temperature limit trips repetitively
due to a serious issue with equipment or installation. In this

®

case, the Fastra x

FEB will remain in cold air mode until the

issue has been resolved and the unit has been manually
reset by pressing the “MANUAL START” button.

6. Remote Timeout Mode: This mode prevents the possibility

®

of the Fastrax

FEB running permanently if the remote start/

stop contacts are inadvertently left closed. While “REMOTE
TIMEOUT MODE” mode is active (default), closure of the
remote start/stop contacts will activate timed remote run
mode. While “REMOTE TIMEOUT MODE” is inactive,
closure of the remote start/stop contacts will activate

“CONTINUOUS REMOTE RUN MODE”.

D.5 Smart Relay Operation

The EATON easy700 series smart relay is a rugged microprocessor

based programmable logic controller, which includes a myriad of

useful function blocks along with 12 inputs and 6 outputs that can

be used to achieve the same control functionality available with
traditional electromechanical relays and timers. There are many
advantages of the smart relay over traditional relay logic systems.

The system wiring using the smart relay is simpler and more

compact, which results in less risk of functionality issues caused

by wiring connections. The smart relay includes a built in display,
which shows diagnostic messages that are helpful in the event that
troubleshooting is required. If desired, the functionality of the smart
relay can be easily adjusted in the field using its display and buttons.
Finally, if desired, the smart relay can be reprogrammed to suit
application specific needs with little or no modification of wiring.

1.1 The preset run time is shown in hours and minutes to

the right of the “SET” label.

1.2 The run timer’s actual elapsed time is shown in hours

and minutes to the right of the “ACT” label.

1.3 The timed run ends when the run timer’s elapsed run

time equals the preset run time.

Controls

2. Continuous Remote Run: While in continuous remote run

mode, the smart relay display shows a message similar to:

2.1 The total time that Fastrax

®

FEB has run in continuous

run mode is displayed. The value to the right of the

“DAY” label indicates the portion of the elapsed time

in days, while the value to the right of the “HR” label
indicates the remainder of the elapsed time in hours
and minutes. For instance, the message indicates that
the Fastrax

®

FEB has been running for 3 days, 8 hours,

and 10 minutes in continuous remote run mode.

3. Cool Down: While the Fastrax

®

FEB is running in cooldown

mode, the smart relay display shows a message similar to:

1.1 This fault message indicates that the duct heater has

been disabled due to an over-temperature condition.

This condition may be a transient issue that happens

only in rare circumstances or a more serious issue
that happens regularly. If the primary high temperature
limit thermostat trips often enough, it will eventually
be forced into cold air mode and the snow clearing
performance of the Fastrax

®

FEB will be impaired.
Please see Section G. Troubleshooting for more
information.

2. Cold Air Mode Forced: If the primary high temperature limit

thermostat has tripped 10 times over the course of a day,
the smart relay display shows:

18

3.1 The preset cooldown time is shown in minutes and

seconds to the right of the “SET” label.

3.2 The run timer’s actual elapsed time is shown in minutes

D.8 Protection

1. Primary High Temperature Limit Thermostat: The purpose

of this device is to provide a first line of defense against
overheating conditions that could otherwise cause equipment
damage or failure. If there is an issue with the installation
of the Fastrax
restriction or a malfunctioning blower, the heating elements
and ducting downstream of the elements could run at an
elevated temperature. If this temperature is sufficiently high to
be of concern, the primary high temperature limit thermostat
contacts should open, de-energizing the duct heater elements

to allow the Fastrax® FEB to cool down. Once the Fastrax®
FEB has cooled sufficiently, the primary high temperature
limit thermostat contacts should automatically reclose and
the duct heater elements should re-energize. If the cause
of the overheating condition is transient and goes away on
its own, then the Fastrax
it should. If, on the other hand, the cause of the overheating
condition is not rectified, the Fastrax
alternate between energizing and de-energizing the duct
heater elements during operation until cold air mode is
forced on indefinitely, which could negatively impact snow
clearing performance.

2. Backup High Temperature Limit Thermostat: The purpose

of this device is to provide a second line of defense
against overheating conditions that could otherwise cause
equipment damage. If there is an extreme overheating
condition that causes the equipment to run at a much
higher temperature than the threshold of the primary high
temperature limit, or if the primary high temperature limit
has malfunctioned, then the backup high temperature
limit thermostat contacts should open, de-energizing the
duct heater elements to allow the Fastrax
down. The contacts of the backup high temperature limit
thermostat will remain open and prevent the duct heater
elements from energizing until this thermostat is manually
reset. The backup high temperature limit thermostat should
only be manually reset if the heater has been thoroughly
checked and evaluated to be in proper working order.

FEB to cool

3. Motor Controller: The purpose of this device is to protect the

motor from medium and long term overcurrent conditions
that could otherwise damage it and result in a costly
replacement. There are many common causes of motor
overloads that must be mitigated, including excessive
loading on the blower impeller due to clogged ducting or
bearing friction. The class 10 tripping characteristic curve
of the motor controller has been carefully designed to
prevent degradation of the motor windings in these overload
conditions. Without this protection, the otherwise long life of
the motor could be cut short if an overload occurs.

4. Circuit Breakers: The purpose of these devices is to

protect and isolate the Fastrax

®

FEB electrical components
including the controls and duct heater elements from short
term overcurrent conditions and from line and ground faults.

The codes printed on the labels of these breakers and their

corresponding functions are listed in the table found in
subsection D.9 Control Panel Layout.

4.1 In the event of a fault, one of these breakers should trip,

disconnecting the faulted circuit from the rest of the

®

Fastrax

FEB’s circuits. After the fault is cleared and
its underlying cause is resolved, this breaker must be
manually reset to restore normal operation.
