HL-6900 Multi-function Humidity Device with

Temperature Sensor Installation Guide

Installation

Important: The HL-6900 Series Multi-function

Humidity Device is intended to provide an input

to equipment under normal operating conditions.

Where failure or malfunction of the HL-6900 Device

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 HL-6900

Device.

Important: Le HL-6900 Series Multi-function

Humidity Device est destiné à transmettre des

données entrantes à un équipement dans des

conditions normales de fonctionnement. Lorsqu'une

défaillance ou un dysfonctionnement du HL-6900

Device risque de provoquer des blessures ou

d'endommager l'équipement contrôlé ou un

autre équipement, la conception du système de

contrôle doit intégrer des dispositifs de protection

supplémentaires. Veiller dans ce cas à intégrer de

façon permanente d'autres dispositifs, tels que

des systèmes de supervision 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 HL-6900

Device.

Parts included

• HL-6900 Device

• Two 8 in. x 1 in. Phillips-head sheet metal screw

• Washer for use with conduit fitting; conduit fitting and

nut not provided

Tools required

• Hole saw with 1 in. (25 mm) diameter blade

• Drill with 1/8 in. (3 mm) drill bit

• No. 2 Phillips screwdriver

• Pliers

• Gasket, sealer, or other materials to seal the area

between the unit and the duct

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.

When you select a location for the HL-6900 Device,

consider the following:

• Position: The HL-6900 Device is designed for duct

mounting in any position, except with the probe tip

pointed up.

• Duct Diameter: Recommended minimum diameter

(round ducts) or width (square ducts) 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 might

be exposed to condensation.

Application setup

Before installation, configure the multi-function humidity

device for the following: input and output signals, and

setpoint and proportional band.

The HL-6900 Device has a setpoint potentiometer,

adjustable from 60% to 95% Relative Humidity (RH), and

a proportional band potentiometer, adjustable from 5%

RH to 30% RH. See Figure 1 to change the setpoint or

proportional band for the application desired. See Table

1 and Table 2 for more details about the input and output

jumper setting.

Wiring 4. About this task: CAUTION: Risk of Electric Shock. Disconnect the power supply before making electrical connections to avoid electric shock. ATTENTION: Risque de décharge électrique. Débrancher l'alimentation avant de réaliser tout raccordement électrique afin d'éviter tout risque de décharge électrique. Observe the following when wiring the unit: • Do not run low voltage wiring in the same conduit as line voltage wiring or other conductors that supply highly inductive loads.
