Efficient Snow and Ice Management with ASE DS Series Sensors: A Complete Guide

Maximizing Efficiency and Safety with ASE DS Series Snow Melt Sensors

Winter weather brings unique challenges, from ensuring pedestrian safety to protecting valuable infrastructure from the dangers of snow and ice buildup. Automated Systems Engineering, Inc. (ASE) has developed the DS series of snow melt sensors and controllers, providing an innovative and efficient solution for combating winter’s harshest conditions. Distributed by ZOT Supply, these sensors strike a balance between affordability, sophistication, and advanced control capabilities. Let’s delve into the benefits of the ASE DS series and why they’re the go-to choice for efficient snow and ice management.

The ASE DS series sensors and controllers are engineered for the toughest conditions. Each unit is housed in a durable NEMA 3R-rated enclosure, designed to withstand outdoor environments. The internal electronic components are rated for operation between -40°C (-40°F) and +85°C (+185°F), ensuring reliability even in extreme weather. For added safety and compliance, all line voltage units are ETL UL Standard 508/CSA C22.2 No. 14 listed, and they adhere to European CE EMC directives, making them suitable for both domestic and international applications.

Unlike traditional "potted" sensors that often require full replacement when they fail, the DS series offers full access to the sensor electronics. This design allows for easy configuration, adjustment, and field repairs. The precipitation sensor is replaceable, meaning you can restore your system to "like new" performance with minimal cost and effort—a significant advantage over having to replace an entire controller.

Managing multiple part numbers for various sensors can be a logistical headache. ASE solves this problem with a standardized approach:

• Universal Voltage Compatibility: Each line voltage DS unit operates on any input supply from 100VAC to 277VAC, eliminating the need for separate units for different voltages.
• Low Voltage Options: For hydronic and other low voltage systems, the DS-224C and DS-824C provide seamless integration.
• Field-Selectable Options: All adjustments and configurations can be made on-site, reducing the need for excessive inventory and ensuring shorter lead times.

This standardization not only simplifies ordering but also minimizes inventory costs and increases operational efficiency.

The DS series operates using a combination of a base-mounted temperature sensor and a heated precipitation sensor. Here’s how it works:

• Environmental Sensing: When rain or snow lands on the precipitation sensor, the traces are bridged, signaling the presence of moisture.
• Self-Clearing Mechanism: The sensor’s built-in heater rapidly evaporates the moisture, ensuring uninterrupted operation.
• Configurable Actions: The microcontroller processes the environmental data and triggers appropriate actions based on user settings, such as activating heating systems or deicing mechanisms.

Each DS unit can be customized to suit specific applications. For example, the DS-4C features two control relays that can be configured for:

• Low-temperature detection
• Rain or snow detection
• Simultaneous control of larger loads

Additionally, the "Delay Off" drying cycle ensures that surfaces remain dry after snow and ice have melted, reducing the risk of refreezing and enhancing safety.

The DS series sensors are highly versatile and can be deployed in various settings, including:

• Satellite Antenna Deicing: Prevent signal interruptions by using remote-mounted sensors on feed booms.
• Roof and Gutter Deicing: Protect infrastructure by installing sensors in gutters or downspouts.
• Pavement Heating: Ensure pedestrian safety by activating snow melt systems for walkways and driveways.

ASE has made remote operation and monitoring simple and efficient. Each DS unit includes a control/monitor interface, allowing users to:

• Remotely monitor system activation
• Manually activate or disable the controller

Optional accessories like the DP-7B rack-mounted or CDP-2 wall-mounted remote panels further enhance control capabilities.

ASE has addressed common issues users may encounter:

1. Sensor Triggering Without Precipitation:
   • Mineral buildup from evaporated moisture can cause false triggers. Clean the sensor grid every four months with water and a non-metallic cleaning pad.
2. No Voltage Output:
   • Ensure proper wiring and check that one load lead is connected to your voltage source.
3. Unexpected Operation:
   • Verify configuration switch settings and perform a power cycle to apply changes.
4. Low-Temperature Cutoff (LTC):
   • Some models include LTC to inhibit triggering below 15°F. This can be disabled if needed.
5. Wet Snow Performance:
   • Adjust the trigger temperature higher to ensure effective operation during wet snow conditions.

The ASE DS series offers unparalleled benefits for snow and ice management:

• Reliability: Built to withstand harsh conditions with minimal maintenance.
• Cost Efficiency: Replaceable components reduce long-term costs.
• Versatility: Configurable settings accommodate diverse applications.
• Ease of Use: Simple installation and intuitive operation.
• Standardization: A single part number simplifies ordering and inventory.
