SNOW SWITCH FAQS – PD-PRO 

BLANK
Why is my supply light flashing?

A flashing supply light indicates a missing or broken High Temperature Limit sensor.  This sensor is required to make the APS-C series controller to work.  It is required on all of the APS-C series controllers.

The sensor is not polarized and must be connected to pins 10 and 11.  Refer to figure 22 in the manual.  If the Class two terminals are black with screw connections problems can occur when the screws are over tightened. 

Why doesn’t adjusting the High Temperature Limit dial turn the unit on?

The high temperature limit dial is used to set the maximum temperature that the unit will work at.  When the High temperature limit sensor detects a temperature higher than what is selected on the dial it overrides the system and shuts it off.  This function can be used to further regulate slab temperatures in pavement applications and as a warm weather override when the system is used for roof and gutter melting applications.

When the system was installed the high temperature sensor was not installed, can I still make the unit work?

The high temperature limit sensor is intended for two purposes, either as a slab sensor when the APS-C series unit is used for heating sidewalks, patios or drives or for ambient air temperature when the unit is used for roof and gutter melt systems.

 

In roof and gutter applications the sensor is run outside the building and placed in a location that is out of direct sunlight and away from other heat sources such as air conditioners or vents.

 

In slab applications this sensor is usually installed in conduit.  If this was not provided for when the slab was poured then the alternative is to either use it as an ambient air sensor or bypass this function all together.

 

The high temperature limit can be bypassed by installing a 470K-ohm resistor in place of the sensor on pins 10 & 11 Refer to figure 23 in the manual.

 

Can I simulate a sensor call for heat to test the system?

Yes, by putting a jumper between pins 1 and 2 of the class two terminal blocks the system will respond as if the sensor were seeing snow conditions.  The snow and heat indicators will come on and relay or contactor will be pulled in.

Why won’t the sensor turn on the system when it is snowing outside?

There can be several reasons for this.  First start by checking the sensor supply voltage between pins 2 and 3 of the class two terminal blocks. It should be close to 24 VDC (the label on some unit incorrectly say 24VAC).  If there is no voltage then check the fuse on the board behind the terminals. 

 

If you have already simulated a sensor’s call for heat and the controller is not suspect then examine the wiring to the sensor, damaged wires can cause loss of signal from the sensor or power to the sensor.

 

Lastly the snow sensors must see both a temperature below 38F and moisture on the moisture grid.  High wind conditions can keep snow from accumulating on the moisture grid so consider how the weather is affecting the snow sensor.  High accumulations can bury the sensor and allow the moisture sensors to melt a cave in the snow, which will not allow snow to touch the grid.  This igloo effect will render the sensor inoperative. This effect can be reduced by the use of a moisture cup on GIT sensors and by placing CIT and LCD sensors at a slight angle to allow gravity to help remove excess snow.

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.

Why is the GFEP light flashing on my APS-4C?

This indicates that there is a ground fault on one of the attached SC-40C satellite controllers.  The SC-40C that has the ground fault will have a solid red GFEP light and will not allow the heaters to be powered.  Isolating the heater leg that has the ground fault is done in the same way as on the Isolating a ground fault on the APS-4C.  If the light is flashing but there is no indication of a ground fault on the APS-40C then review the wiring of the communication wiring between the APS-4C and the SC-40C.

How do I connect my SC-40C to my APS-4C?

These connections are done on the Class 2 terminal blocks on both units as follows

APS-4C Pin                             SC-40C Pin                       Next SC-40C Pin

               4——————————    4 ——————————   4

               5 —————————–     6 ——————————   6

7——————————-   5

7 ——————————-  5

What is the EMC light for?

EMC stands for Energy Management Computer, which can used to remotely monitor and control the APS-C series ice melt controllers.

 

These connections are made to the Class 2 connection terminal block on pins 14 through 22.  The following diagram will aid in making these connections.

 

The EMC can use the override on and override off to turn the systems on and off and provides internal dry contacts for monitoring and alarms.  For a complete description of how the EMC works refer to the manual page 15.

Do I need to attach a snow sensor to the SC-40C?

No the SC-40C is controlled completely by the attached APS-4C.

 

 

Why does the snow light go off on the APS-4C but remain on for the SC-40C’s?

 

This occurs because the APS-4C gets its command from an actual snow sensor where the SC-40C’s get their command from the APS-4C. 

 

When the snow sensor’s moisture grid dries out, it no longer sends a snow present command to the APS-4C so it’s snow light goes out.  However the APS-4C remains on for the duration of the hold on time set on the front panel dial.  While the hold on time continues the APS-4C continues to send a snow signal to the SC-40C’s and hold them on as well.  When the hold on time is complete all of the controllers will turn off.

 

Why is there a delay between when the APS-4C turns on and when the SC-40C comes on?

This delay is programmed into the system in order to reduce surge current.  When the heaters are turned on they will have a large inrush of current for a few seconds.  If all the heater circuits came on at the same time the inrush current could be large enough to trip the main breaker in supplying panel.  This 5-second delay is meant to reduce this problem.

How can I test the snow sensor?

The APS-3C and APS-4C controllers utilize the CIT-1 aerial snow sensor, the GIT-1 gutter snow sensor and the SIT-6E pavement snow sensor to detect weather conditions. All three of the sensors that work in the same way, they require a temperature below 38F and moisture on the moisture grid.  Both the CIT and GIT have a protruding tube that contains the temperature sensor and the moisture grid is on the opposite side.

 

In all cases using a moist rag or paper towel and a freeze spray or ice to test the sensor.

Is there a way to make the system come on with temperature only?

The APS-C series systems are designed to turn on and off, as the weather requires heat to deal with snow or icing conditions.  Although a thermostatic dry contact switch can be used to override the system on for temperature alone, is not recommended since it will reduce the efficiency of the system.  Running the heaters on cold days that do not have snowfall will not hurt anything but your budget.

 

If you must do so choose a thermostat with dry contacts that close when the temperature is below 40F and connect it to the override-on terminals of the EMC section of the Class 2 terminal block.

Can I use the APS-4C to drive external contactors for more circuits?

No.  Doing so will cause the GFEP circuit on the APS-4C to detect the inductive load of the contactor coil as ground fault and alarm the system every time the contactor is turned on. 

 

The APS-3C is designed without an internal GREP circuit so it will work with external contactors or direct heater loads.  In both of these applications you must provide a GFEP breaker to power the heater circuit.

What is the difference between the 277 single phase unit and the 277/480 three phase unit?

The difference is the step down transformer that provides the power for the internal circuitry.  On the 277 single phase the transformer is 277 VAC to 24 VAC and you will note that its primary winding is connected to the top and middle poles on the contactor.

 

On the 277/480 three phase unit the transformer is 480VAC to 24VAC and the primary winding is connected to the top and bottom poles on the contactor.

Installation Instructions

  1. Download and save it to your local drive, thumb drive, or similar media. For the purposes of these instruction we will assume that you chose to save the file in your “My Documents” folder.
  2. Uncompress the contents of the zip file.
  3. Open the windows command window by clicking on start, run and type “cmd” then click OK. This will open a black screen window with dos command lines. You will also see a line like “C:Documents and Settings(User)>” where (User) is the name of the directory the “My Documents” folder is in. A flashing cursor will be next to the >
  4. Using the windows command line:
    • Change directories to the location you uncompressed the files to in step 2. You can do this by typing “CD my documents” and pressing return. The “CD” is the dos command for change directory to the directory you list. “CD” should take you all the way back to the root directory (C:). Typing “CD..” will take you back one directory (C:Documents and Settings). If you make a typing mistake and there is no directory if you hit the return then it will return the line unchanged.
    • Type “cscript ncfirm.vbs 192.168.52.9” and press return. This will start loading files to the NETCOM. The 192.168.52.9 is the default IP address of the NETCOM, which you can change later, if you wish to suit your network. If you have already changed the IP address then use that address instead of the default.
    • Wait for the command to complete. (This will take some time so be patient. Once the lights begin flashing on the dehydrator it is alright to exit the windows command line if you wish but the installation has another step so you may want to wait.)
  5. You will be prompted to wait for the front panel lights to stop flashing while the unit reboots. Wait for the lights to stop flashing before continuing.
  6. Using the windows command line:
    • Type “cscript ncpages.vbs 192.168.52.9 and press return. This will again start loading files to the NETCOM.
    • Wait for the command to complete.
  7. Open a web browser and go to http://[your_ip_address or your_network_name]/. You should see the new user interface.

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

ETI TRACON – HEAT TRACE – HELPFUL TIPS

TRACON FAQ’S – FPT-130

 

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.

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.

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.

ANTHONY MACRI NAMED ETI’S DIRECTOR OF ENGINEERING

TUESDAY, SEPTEMEBER 29, 2020 (SOUTH BEND, IN) The ETI Network of Companies (ETI, ETI Fab, and ETI Controls) is proud to announce the promotion of Anthony Macri to Director-Engineering. Anthony is a proven leader at ETI with over 5 years of experience as an Electrical Engineer.  In his first year with ETI, Mr. Macri’s background and knowledge were vital in the creation of ETI Controls (ETI’s In-house Board Building Division).

 

“Anthony was influential on The ETI Network Grand Strategy creation and is now leading the execution of the plan” stated Ben Crawford President & CEO”.  We are excited he accepted the position and with his energy and skill he will create an environment of speed and innovation of ETI custom designed products while launching private label manufacturing for new customers”.

 

Anthony received a B.S in Electrical and Computer Engineering Technology from Purdue University.  Prior to joining ETI, Anthony held the position of Electrical Engineer at Roush Industries in the Detroit area with a focus on wire harness automotive engineering. 

 

“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
