TRACON FAQ’s – FPT-130

BLANK
Why is the blue low temp LED on?

The blue LED lit solid indicates when the temperature falls to 32 °F (0 °C) for all setpoints except the 30 °F (-1.1 °C) setpoint. For the 30 °F (-1.1 °C) setpoint the LOW TEMP alarm will indicate when the temperature drops to 28 °F (-2.2 °C).

What do the blinking lights mean?
  • POWER indicator – This green LED lit solid indicates that the FPT 130 is receiving power.

– Blinking indicates a calibration error.

 

  • HEAT indicator – This yellow LED lit solid indicates when the heater is energized.

– Blinking asymmetric (1/2 sec off × 1–1/2 sec on) – Low Current Alarm, heater relay closed.

– Blinking asymmetric (1/2 sec on × 1–1/2 sec off)

– Low Current Alarm, heater relay open.

– Blinking fast – Stuck relay.

 

  • LOW TEMP indicator – This blue LED lit solid indicates when the temperature falls to 32 °F (0 °C) for all setpoints except the 30 °F (-1.1 °C) setpoint. For the 30 °F (-1.1 °C) setpoint the LOW TEMP alarm will indicate when the temperature drops to 28 °F (-2.2 °C).

– Blinking indicates sensor fault.

– Blinking fast – indicates High Temperature alarm.

  • ALARM indicator – This red LED lit solid indicates when there is a high ground fault current. – Blinking indicates a GFEP circuit failure (this light will also blink while system is preforming a self–test).
How do you disable the low temp alarm?
  • Hold down the red TEST/RESET pushbutton for approximately ten seconds.

– After the first five seconds the unit will go into Manual Mode, energizing the heater cable if it is not all ready energized.

– After the second five seconds the unit will enter the LOW TEMP blue LED edit mode. This is indicated by the blue LED flashing rapidly. Release the button at this point. (The unit will exit Manual Mode.)

Note: The blue LED may flash for a couple of seconds after releasing the red TEST/RESET pushbutton.

  • The blue LED will indicate whether the LOW TEMP Alarm is currently disabled or not. – If the blue LED remains on the LOW TEMP Alarm is currently enabled.

– If the blue LED goes off the LOW TEMP Alarm is currently disabled.

– To keep the setting as it is wait five seconds and the unit will resume normal operation. – To change this setting press the red TEST/RESET pushbutton within five seconds. The new status of this setting will show for three seconds before the unit resumes normal operation.

Note: The blue LED will flash rapidly before exiting the LOW TEMP blue LED editing mode and resuming normal operation.

Can I use an RTD?

No, the FPT-130 is meant to be used with only the supplied thermistor sensor.

What voltage can I supply it with?

The FPT 130 operates from 100 – 277 V ac at 50/60 Hz.

Can the unit interface with BMS? Can it communicate with BACNET or MODBUS?

No, the FPT 130 provides a summary alarm via a dry contact relay.  This relay is energized whenever the unit is powered.  So, with power off the NC contact is closed, and the NO contact is open.  When the unit is powered these are in the opposite state.  A fault will de-energize the alarm relay and close the NC contact.  This allows for a default, power loss alarm without power.

Can you extend the length of the temperature sensor?

Yes, you can extend the sensor up to 2,000 ft. cable for enhanced installation options

What type of wire do I need to extend my lead length? Sensor vs. Thermistor

When installing ETI sensors and thermistors, you may find that you need to extend the leads greater than what’s already provided from the factory. Because the Snow Switch sensors operate at a higher voltage and use higher current than the thermistors, the recommended wire gauge differs between the two. To avoid confusion, we’ve created this writeup to explain our recommendations for extending the leads on ETI’s Snow Switch sensors and thermistors. For Snow Switch sensors, ETI recommends #18 AWG wire for up to 500 ft and #12 AWG wire for anything greater than 500 ft. On several product datasheets, #12 AWG wire is limited to 2000 ft because the average sensor runs 24 volts at 250 mA of current to limit voltage drop and low current issues.

 

Regarding the temperature sensors (thermistors), the requirement differs because the thermistor runs at 5 volts and approximately 2 mA of current, which is a negligible line loss. The main difference resides in the line resistance. ETI controllers use a 100k ohm thermistor with a negative temperature coefficient, so when the temperature decreases, the resistance increases. Since the thermistors are used for snow melt and freeze protection, the range of resistance used is 2.7Meg ohms (-40F °) to 75.2k ohms (+90F °). This means a single digit degree change will be marked by a resistance change of between 800k ohm per degree on the cold end to 2k ohms per degree on the hot end.

 

Since #22 AWG wire (which is what is specified on the thermistor) has a resistance value of 16.5 ohms per 1000 ft, it can be observed that the wire gauge will not make a considerable difference in the measurement of temperature. This means it is acceptable to use a #22 AWG wire to extend the cable.

 

#18AWG wire is 6.51 ohms per 1000 feet of wire and #12 AWG is 1.62 ohms per 1000 feet. It is worth mentioning because the #22 AWG may be the most cost-effective solution compared to the #18 or #12 AWG wire.

 

With all of that said, if the wire meets the work requirements for insulation and protection of the wire and meets ETI’s wire recommendations, it is acceptable to use #22 AWG or larger to extend the wires for the thermistor, and #18 AWG wire for up to 500 ft and #12 AWG wire for anything greater than 500 ft for ETI’s Snow Switch sensor cables

Heat Trace with Plastic Pipes

Heat Trace with Plastic Pipes

Heat cable can be used on plastic pipes but the plastic’s durability and thermal properties must be considered. Plastic has approximately 125 times the thermal resistance than steel but is also more susceptible to damage from direct high temperatures. The key to heating plastic pipes is to use a lower temperature and distribute it as evenly as possible.

It is always a good idea to use a heat trace system with an automatic thermostat and control, but especially so when using heat trace on plastic pipe. An automatic heat trace control can monitor and maintain the system’s temperature, alarm for problems, and shut off the heat cable to prevent damage.

There is heat cable designed specifically for plastic pipes that is self-regulating and has limited wattage. Self-regulating heat cables have a conductive core between two bus wires that becomes more conductive when cold. This system increases the power to the cold spots and decreases it to the warmer areas, which provides a more even heat source.

The manufacture of the plastic pipe should be able to provide information as to the maximum temperature and how close heat cable can be spaced or wrapped on the pipe to avoid damage. Some applications may require heat cable to be applied to opposite sides of the pipe at a lower temperature to distribute the heat more evenly, avoiding one direct area of concentrates heat which may damage the pipe.

It is recommended to install a foil material between the pipe and the heat cable to avoid direct contact and help provide a more even heating. If doing this place the heat trace control thermostat directly onto the pipe with no foil over it or between it and the pipe to ensure a more accurate reading.

You can use heat cable on plastic pipes as long as you follow precautions, such as determining your pipe’s thermal capacities, selecting a self-regulating, low wattage heat cable and using an automatic heat trace control with safety functions. Following these guidelines will help prevent damage and increase the life of your heat trace system.

SNOW SWITCH FAQS – PD-PRO

WHY DO I HAVE A RED GFEP LIGHT ON?

 

The GFEP indicator will come on when a ground fault occurs in one of the heater circuits.  The insulating resistance of the heater cable is breaking down or the cable has been damaged allowing current to pass to ground thru an incorrect pathway.  Left un-repaired the cable could cause a fire if it continues to be powered.

 

When a ground fault is detected the controller will not allow power to be applied to the heater circuits until the problem is corrected.  You can isolate the offending heater by removing all the heaters and reinstalling them one at a time to discover the heater with the fault. An alternative to this method is to use a Meg-ohm tester and test each heater leg per the manufactures specifications.

 

You will need to contact the heater manufacturer for instructions on how to locate the problem and fix it. Most heaters can be repaired with repair kits or splice kits but the manufacturer will be able to provide the details.

FREQUENTLY ASKED QUESTIONS – TRACON TEMPERATURE CONTROLLER

Temperature Controller – GPT-130

 

 

 

 

 

 

 

 

QUESTION –

WHY AM I GETTING A GROUND FAULT WHEN THE GROUND FAULT CURRENT IS SO LOW?

 

ANSWER – 

The GPT-130 displays a number of alarms, beside the ground fault it will also alarm for low current.  If you have disconnected the load to trouble shoot a possible ground fault in the heater cable, then you probably have a Low Current Alarm and a very low default ground fault current reading.

You can tell the difference by looking closely at the display, it will tell you what the alarm is for.  If you want to clear the low current alarm so you can test the controller then go into the configuration menu and disable the Low Current Alarm.

Remember to re-enable the Low Current Alarm when you are done testing and ready to put the unit back into service.

“I’m very excited about this new opportunity here at ETI,” Macri stated.  “ETI has established a great team of industry experts over the years and it is truly an honor to work with them every day.  With a continued focus on quality and product development, I see great things on the horizon for the entire ETI Network of Companies.”

September Is Sensor Placement Month At ETI

SENSOR PLACEMENT FOR SNOW & ICE MELT APPLICATIONS

 

A great number of service calls come in with the common problem of the heaters not coming on even though it is snowing outside or there is ice buildup. After trouble- shooting the system it is discovered that the equipment is fine but there is no snow or ice on the sensor.

 

The proper placement of sensors is critical for the snowmelt system to operate. This is especially true if only one sensor is used, multiple sensors can be a little more forgiving for incorrect placement but to get the most out of the system it would be advisable to locate as many sensors in the “sweet spot” as possible.

 

The best person to determine the sweet spots for the sensors is the installer but to do so the installer needs to consider several parameters when considering the site and the final location of the sensor or sensors. These include but are not limited to:

 

          1.  Prevailing winds

          2.  Obstructions

          3.  Orientation of buildings and their affects on snow and drift patterns
