HE-67xx Humidity Element with Temperature Sensor

Installation

IMPORTANT: Use this HE-67xx Humidity

Element with Temperature Sensor only as an operating control. Where failure or malfunction of the humidity element with temperature sensor could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the humidity element with temperature sensor.

IMPORTANT : Utiliser ce HE-67xx Humidity Element with Temperature Sensor uniquement en tant que dispositif de contrôle de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du humidity element with temperature sensor risque de provoquer des blessures ou d'endommager l'équipement contrôlé ou un autre équipement, la conception du système de contrôle doit intégrer de s dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autre s dispositifs, tels que des systèmes de supervisio n ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement du humidity element with temperature sensor.

The humidity elements are available in both a wall mount or duct probe package to suit a variety of sensing application needs. Refer to the Mounting section for a complete list of the parts included and tools required for installation.

Location Requirements

IMPORTANT: To avoid damage to the circuit

board and components, do not mount the unit in a location where high concentrations of corrosive vapors are present.

Wall Mount Humidity Element

Locate the humidity element on an inside wall, f ree from drafts, out of direct sunlight, and where the element is not exposed to excessive vibration. Be careful not to drop the unit.

Mount the wall mount element at a height of 4 to 6 ft (1.2 to 1.8 m) above the floor and with one of the two mounting direction arrows on the circuit board pointing up. (See Figure 1.) Improper orientation can result in heat-induced error.

Figure 1: Mounting Direction Arrows

and Output Jumper Location

Duct Probe Humidity Element

Place the duct probe humidity element in a location that complies with the following:

• Position: Designed for duct mounting in any position, except with the probe tip pointed up.

• Duct Diameter: Recommended minimum diameter (round ducts) or width (square duct s) is 12 in. (305 mm).

• Air Stratification (when the unit is mounted on the discharge side of the fan): Recommended location is at least 8 ft (2.4 m) downstream from humidification equipment, where duct air and water vapor are sufficiently mixed. Avoid areas where the probe may be exposed to condensation.

Wiring

To mount the duct probe humidity element, ref er t o Figure 5 and proceed as follows:

Figure 5: Duct Probe Humidity Element

Assembly and Mounting

1. Remove any excess insulation from the duct that prevents the probe from extending a minimum of 3 in. (76 mm) into the air stream.

2. Use the hole saw to make a 1 in. (25. 4 mm) hole in the duct for inserting the probe.

3. Pull the plastic cover off the housing.

4. Insert the probe into the du ct , and use the housing as a template to mark the location of the holes for the mounting screws.

5. Remove the unit, and drill a 1/8 in. (3 mm) hole for each mounting screw.

Wiring

WARNING: Risk of Electric Shock.

Disconnect the power supply before making electrical connections. Contact wit h compon ents carry ing hazardous voltage can cause electric shock and may result in severe personal inj ury or deat h.

AVERTISSEMENT : Risque de décharge électrique. Débrancher l'alimentation avant de réaliser

tout branchement élect rique. Tout contact av ec des composants conducteurs de tensions dangereuses risque d'entraîner une déc harge él ectriqu e et de provoquer des blessures graves, voire mortelles.

Observe the following when wiring either ty pe of element:

• Do not run low voltage wiring in the same conduit as line voltage wiring or other conductors that supply highly inductive loads.

• Use 18 or 24 AWG wire.

• Make all wiring connections in accordance with t he

National Electrical Code and all local regulations.

Wall Mount Humidity Element

To wire a wall mount model:

1. Connect the wires to the appropriate positions on the terminal block. (See Figure 6.)

IMPORTANT: Remove the unit before drilling to prevent any metal remnants from falling onto the circuit board.

Seal any holes created during installation to help reduce drafts and for more accurate humidity readings.

6. Use a gasket, sealer, or oth er m eans to seal the area around the 1 in. (25.4 mm) hole between the unit and the duct.

7. Reinsert the probe, and se cure the housing to the duct using the two No. 8 screws provided.

2. Place the cover over the base, an d tighten the button-head screw (shown in Figure 3) on either side of the unit to secure.

3. Choose the appropriate faceplate (vertical or horizontal), depending on the mounting positio n of the unit.

4. Remove the adhesive-backed paper from the faceplate, and apply to the cover.

Duct Probe Humidity Element

To wire a duct probe model:

1. Route the wires from the controller to the unit through the conduit hole in the housing.

IMPORTANT: If using a conduit fitting (not provided), a washer is provided to support the fitting in the housing. If the washer is not used, the fitting could stress the plastic housing.

2. Break out the appropriat e knockout from the cover (shown in Figure 5) with pliers to accommodate the wiring or conduit if used.

3. Connect the wires to the appropriate terminals of the wiring block. (See Figure 7.)

Troubleshooting

If the humidity element is not functioning properly:

1. Verify the unit is mounted in a locat i on that is indicative of space humidity and temperature (away from drafts, moisture, sunlight, etc.).

2. Use a humidity tester with accuracy greater than the element (±2% between 20 and 80% for 2% models; ±3% between 20 and 80% for 3% models), such as an optical dew point hygrometer, to determine the percent of Relative Humidity (RH).

Note: The humidity tester and the element must

sense the air at the same temperature. Before testing, be sure to wait 30 to 60 minutes for the tester to stabilize to ambient temperature and humidity. A temperature difference of as little as 1F° (0.6C°) can cause a difference in measured RH of over 2.5% RH.

3. Calculate the percent of RH i ndicated by the element as follows:

For 0 to 10 VDC output, multiply the output voltage

by 10. For example: 7.5 VDC x 10 = 75% RH

For 0 to 5 VDC output, multiply the output voltage

by 20. For example: 3.5 VDC x 20 = 70% RH

Note: ±0.9F° (±0.5C°) corresponds to an error of

about ±2% RH at 25°C if RH is at a high level, e.g., 70%.

Figure 7: Wiring the Duct Probe Humidity Element

4. Press the cover onto the base.

4. Compare the RH readings between the humidity tester and the element. If the difference is more than the sum of the allowable errors, replace the element.
