Difference between 277 single phase and 277/480 3 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.

Consult a professional and or your electric provider to determine what configuration is needed.

APS single phase and three phase wiring

CAN THE APS ACTIVATE ON 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 only, 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.

 

APS Snow Sensor Overide for temperature only
External contactors used with the APS-4C?

No, using external contactors will cause the GFEP circuit on the APS-4C to detect the inductive load of the contactors coil as ground fault and alarm the system every time the contactor is turned on. In order to increase the size of the application, a SC-40C satellite control can be used with the APS-4C without triggering the ground fault protection.

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.

 

Flashing supply light.

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.

sensor connections for flashing supply light
Delay between SC-40C and APS-4C?

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

This delay between the APS-4C and the SC-40C 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.

APS-4C connected to SC-40C

Snow light on SC-40C stays on longer than APS-4C

The snow light stays on longer for the SC-40C than the APS-4C 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.

APS-4C, SC-40C connection for snow light
Is a snow sensor required for a SC-40C?

No, the SC-40C does not use a snow sensor, it is completely controlled by the attached APS-4C. However, the SC-40C does require the High-Temperature sensor Thermistor to be connected (or bypassed with a 470K-ohm resistor) in order for the unit to operate. The SC-40C only acts to extend the load capabilities allowing you to energize a larger heater area off a APS-4C unit.

SC-40C, APS-4C and snow sensor digram
Temperature sensor was not installed

The high limit temperature 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

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?

Yes, you can simulate a sensor call for heat to test the system 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.

How to simulate a sensor call for heat
Snow sensor not detecting snow outside?

There can be several reasons for this. First, start by checking the snow 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.

Snow sensor diagnostics

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.

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

APS-4C to SC-40C 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————————–X
X———————7————————–5

Connection from APS-4C to SC-40C
Connection from SC-40C to SC-40C
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.

What is the EMC light for?

EMC stands for Energy Management Computer, which can be 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 18.

Energy Management Computer (EMC) Interface
The APS “C” Series interfaces with an EMC via relays. Inputs from the EMC include Override On, which causes heater operation, and Override Off, which inhibits heater operation. These functions are independent of weather conditions and the status of the Hold-On Timer. The interface provides five system status contact closures for the EMC including Supply, Snow, Heater, Alarm, and Temperature Limit.
Absent signals from the EMC, the APS Control Panel controls the heaters based on environmental conditions. Automatic snow melting control is the default condition of the system.
High Temperature Limit dial not turning unit on?
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.

High Limit Thermostat
The calibrated 40°F to 90°F (4°C to 32°C) high limit thermostat prevents excessive temperatures when using constant wattage and MI heaters. It also permits safe testing at outdoor temperatures too high for continuous heater operation. The temperature sensor is included and must be connected to the system for proper operation.
There are two DIP switch configurable operation modes for the high limit thermostat. The factory default operation mode uses the high limit thermostat as a slab temperature regulator, preventing heater operation at temperatures above the High Temperature Limit setting. The optional operating mode uses the high limit thermostat as an ambient air sensor, preventing heater operation at temperatures above the High Temperature Limit setting until the temperature drops back to within the set limits.
The details of operation in each mode are as follows:

Slab Regulating Thermostat Mode
• High temperature causes unit to turn off heaters, if running, and to ignore any call for heater operation from the panel, RCU, or EMC
• High temperature continues any hold-on cycle that was initiated before the high temperature condition. If the slab temperature drops within limits during the hold-on time, the heater will be turned back on
• In a high temperature condition, an APS will still initiate operation of connected SC–40C contactor(s)
• The Heater Cycle functions normally

Ambient Temperature Thermostat Mode
• High temperature causes the unit to turn off heaters, if running, and to ignore any call for heater operation from the panel, RCU, or EMC
• High temperature cancels any Hold-On cycle that was initiated before the high temperature condition
• In a high temperature condition, an APS will not initiate operation of connected SC–40C contactor(s)
• If the Heater Cycle switch is operated in a high temperature condition, the heater(s) will be turned on for a maximum of 30 seconds. A new Heater Cycle cannot be initiated for another two minutes after that.

Snow and ice falling from buildings

How to avoid Snow and ice falling from buildings.

Sheets of snow and ice falling and being blown off buildings are a major hazard that can cause damage to the structure, equipment, and possibly injure someone. Winter conditions have been accounted for in the building design process for a long time, but mostly in a way that only accounts for the weight of the snow and ice acumination and how it will affect the building’s structure. New technologies, innovations, and design trends are requiring that more attention be paid to the dangers of snow and ice when designing and maintaining a building.

Before energy conservation was a big concern buildings were basically large boxes with inefficient insolation that would leak phenomenal amounts of heat that would melt most of the snow and ice almost immediately. Most older building also had simpler designs with smooth walls, and a flat roof with a tall parapet on top to contain snow and ice accumulation so it can be safely drained away. The only real concern back then was how much snow weight could the structure hold, and there were building codes and regulations to account for this.

With advancements in technology, materials, and engineering, buildings are vastly more energy efficient, retaining almost all their heat which creates a colder exterior for snow and ice to accumulate on. Some of these new materials create smooth surfaces snow and ice can slide down in an uncontrolled way causing hazards below. These new materials also allow for more complex building designs, which can create areas where snow and ice can accumulate in unforeseen dangerous ways. These advancements in technologies, materials, and building designs have immense benefits, but also create new problems and hazards which need to be addressed.

The most cost-effective way to address these hazards is in the design phase of the building. There are microclimate professionals that can take data such as local historic weather conditions, surrounding buildings, the building’s airflow patterns, shadow patterns, along with other factors and help identify any potential environmental problems with a building’s design before it is built. These microclimate professionals can also recreate designs in test conditions to see how they perform. It is highly recommended to consult a microclimate professional when designing a building to address potential hazards before the building is built and more expensive fix must be made.

Older buildings will still need to address this problem as they are constantly being upgraded to be more efficient and new buildings being built around them impacting their microclimate. This is where a snow and ice melt system should be installed for safety. Snow and ice acumination that forms in new ways on a building can cause unforeseen consequences. Water can freeze between and behind structures, expanding and causing structural damage. Drainage paths can be overwhelmed in some areas, causing refreezing and accumulation. New areas can become shaded by new buildings in the area causing accumulation where there wasn’t before that needs to be addressed and properly removed. A snow and ice melt system can increase the safety and protection of a building by minimizing the amount of accumulation and keeping drainage paths clear.

Preventing snow and ice buildup is important for the safety of a buildings structure, equipment, and the safety of people below. Whether it is in the design process, or after it is built a building needs to be able to manage snow and ice effectively. Any building’s microclimate should be periodically checked and analyzed to identify and address any problems, especially when they can impact the safety of the people below.

Heat Trace and Hoppers

Many industries that use hoppers utilize heat trace to aid in material flow. Hoppers are elevated storage containers that contain and dispense granular materials. Commonly used in agriculture hoppers are also used in industries such as plastics, chemical, pharmaceutical, energy, and construction. Despite being used to hold and dispense different types of materials they all function the same way and face the same issues.

The main issues with hoppers focus on the material flow. These issues include aspects related to material sticking together or accumulating on the walls of the hopper. This is commonly caused by the particle structure of the material or the presence of moisture. There are many ways moisture can enter the system, these can be caused by environmental conditions or by water or chemicals being applied to the material in the process before being placed in the hopper.

Major environmental factors that can introduce moisture into the hopper material are temperature and humidity. One way to mitigate this is to install a heat trace system onto the hopper. This controls the temperature of the hopper and material avoiding drastic temperature differences which could cause condensation to form on the inside of the hopper.

The application of water or chemicals to the material or the hopper for dust prevention, cleaning or as a step in the production process add moisture to the material. Moisture such as this should be accounted for in the design and selection of a hopper system to insure proper flow. However, despite accounting for this added moisture in the system variable conditions can still cause flow problems. One major problem for hoppers with chemicals or water added is freezing. Material freezing in a hopper can cause the material to clump together or freeze to the walls, causing a blockage or flow problems. This can cause production to be shut down until the material can be thawed or it is manually cleared out. The presence of a heat trace system in these cases will avoid the freezing and allow the material to flow in a predictable manner, avoiding costly shutdowns or disruptions.

There are many pieces of equipment that can be added to a hopper system to aid in the material’s flow such as augers and vibration units, but to combat the effects of variable environmental impacts a heat trace system should be included.
