MSA-1 Installation Operation Instructions

MSA-1

Aerial Moisture Sensor for Connection to MSC‑1 Panel for Snow & Ice

Melting Installations Installation & Operation Instructions

GENERAL

The MSA‑1 sensor detects falling or blowing snow coming in contact with the sensor grid, then sends a signal to the

MSC‑1 to energize heating equipment (snow melting or de‑ icing cables, etc.).

Housing

The sensor operates on low voltage supplied by the MSC‑1 control unit and has a built in 1/2" NPT conduit connection and includes 10´ of wire for connection back to the MSC‑1.

The MSA‑1 is well suited for mast mounting and custom positioning. Rounded features and neutral colour allows the sensor to discreetly blend into almost any environment.

The MSA‑1 connection wire may be extended up to 500´ with an appropriately rated 18‑20 AWG 3 wire unshielded stranded cable.

WARNINGS

1. This is not a “do-it-your-self” product. A qualified electrician must install the MSA‑1.

2. If after carefully reading these instructions you still have questions regarding installation, operation or maintenance of this product, call the numbers listed for assistance.

3. Prior to installation, check the MSA‑1 body enclosure or wires for possible shipping damages. Do not install a damaged MSA‑1 sensor.

4. All heating equipment, controls & associated systems must be installed in compliance with the latest editions of all applicable electrical codes and ordinances.

5. The MSA‑1 has been designed for the sole purpose of connection to an EasyHeat MSC‑1 Control Panel.

The risk of fire or electric shock exists if the MSA-1 is connected to any device other than an MSC‑1 Control

Panel.

6. These instructions must be saved and made available to owners or users of this product and/or transferred to future owners.

8. Secure the MSA‑1 in an area free of obstructions such as trees, shrubs, etc. to prevent any damages to the snow sensor.

9. Avoid excessive shock or vibration.

10. Do not install an MSA‑1 Sensor when the ambient temperature is colder than 32°F (0°C). Installing the sensor below this temperature will damage the connection wire and result in the risk of fire or electrical shock.

MSA‑1 Installations & Operation Instructions

INSTALLATION INSTRUCTIONS

1. Mount the MSA‑1 securely in upright position in an open space, in direct contact with snowfall pattern with a ½” NPT mounting connector. The unit is water‑resistant, but it is not designed to be submerged or immersed in water. Ensure that the mounting location is close (less than 10 feet) to the MSC‑1 Control Panel or a suitable connection box. See Fig.2

2. Ensure that all pipe connections are sealed to prevent any penetration of water inside of conduit or electrical junction box.

3. The MSA‑1 connection wire may be extended up to 500’ with an appropriately rated 18‑20AWG 3 wire unshielded cable.

Ensure that all electrical connections within connection boxes are sealed to prevent any penetration of water.

4. The MSA‑1 is wired directly to the appropriate zone sensor terminal block on the MSC‑1 control panel.

MSA‑1 Installations & Operation Instructions

OPERATION INSTRUCTIONS

The MSA‑1 snow melting control is designed to send a signal to the MSC‑1 control panel indicating when snow or ice conditions exist. The MSC‑1 control panel uses this information, along with temperature data from the TS‑1 to determine when snow‑melting equipment should be energized.

The MSA‑1 may be tested for functionality if outside temperature is below 3°C (38°F), Apply a small amount of moisture onto the surface of the moisture sensor, the MSC‑1 should energise the heating equipment in the associated zone. After this test, dry the sensor, the heating equipment in the associated zone should de‑energize after the pre‑set hold time.

Every year, in the fall the MSA‑1 must be inspected for physical damage and to clean up the snow sensor surface. To clean the snow sensor surface:

1. Disconnect MSA‑1 from the power supply.

2. With a clean wet swab clean up the surface of the snow sensor.

3. Reconnect MSA‑1 to the power supply.
