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.

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.

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

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.

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
®

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