OPERATING INSTRUCTIONS FOR

WIRELESS KILN DATA ACQUISITION SYSTEM

consisting of Kiln Data Collectors and Kiln Data Transmitters

INTRODUCTION

These instructions are intended for professional manufacturers of lumber drying equipment who

use the Wireless Data Acquisition System as part of their kiln control system.

PRODUCT SUMMARY

The Wireless Data Acquisition System features individual, battery-powered

Kiln Data Transmitters, sending the readings they determine via radio frequencies to at least

one Kiln Data Collector.

The Kiln Data Collector picks up data from Kiln Data Transmitters and also determines

dry bulb temperature readings and wet bulb temperature readings (both optional).

Three models of Kiln Data Transmitters are available:

a. Model MCT-TX:

Determining wood moisture content (MC) or equilibrium moisture content (EMC) and

wood temperature (internal sensor)

b. Model WT-TX:

Determining wood temperature (external sensor)

c. Model MCT&WT-TX:

Determining wood moisture content (MC) or equilibrium moisture content (EMC) and

wood temperature (external sensor)

All modules are encapsulated in a highly insulating epoxy compound with maximum hydrolytic

stability protecting them against high ambient air humidity.

The Kiln Data Collector and all Kiln Data Transmitter models can be installed in dry kilns; they

have been designed to withstand the corrosive, hot air conditions existing there. They are

specified for ambient temperatures of up to 85°C/185°F.

OPERATING INSTRUCTIONS FOR WIRELESS KILN DATA ACQUISITION SYSTEM consisting of Kiln Data Collectors and Kiln Data Transmitters INTRODUCTION These instructions are intended for professional manufacturers of lumber drying equipment who use the Wireless Data Acquisition System as part of their kiln control system.

KILN DATA COLLECTOR WARNING Note that the Data Collector does not detect incorrect readings if they are within the measuring range. Whenever false readings are suspected, the accuracy of the readings must be checked by taking comparative readings. To prevent secondary product damage caused by malfunction of the Data Collector, appropriate fail-safe functions must be incorporated into any control system using the readings delivered by the Data Collector.

EXTERNAL CONNECTIONS TO DATA COLLECTORS: Use twisted pair communication cable, shielded. Red (1st pair): Black (1st pair): White (2nd pair): Blue (2nd pair): Shield: +8V to +25.5V (average current consumption: < 35mA) GND RS485 Rx/Tx+ RS485 Rx/TxEarth ground POWER SOURCE: Max.

KILN DATA TRANSMITTERS CONNECTIONS TO TRANSMITTERS: WARNING: FIRE, EXPLOSION AND BURN HAZARD! Every transmitter contains a Lithium battery consisting of one Lithium Metal Cell which is not replaceable or rechargeable.
PAGE 5
HANDLING OF TRANSMITTERS: Transmitters have been designed for everyday use in a harsh kiln environment. However, damage (mechanical and to the circuitry) can occur if these guidelines are not followed to avoid conditions of abuse: Lithium Batteries can only take mechanical shocks to a certain degree. A free-fall of a transmitter on a hard surface can lead to internal short circuits of the battery. In consequence the battery is drained and the transmitter will fail.

TRANSPORTATION OF TRANSMITTERS (all models): Every transmitter contains a Lithium battery consisting of one Lithium Metal Cell which is not replaceable or rechargeable. Lithium batteries are considered hazardous material. When shipping, observe all limitations for primary (non-rechargeable) lithium metal batteries specified in the US national dangerous goods regulations contained in Code of Federal Regulations Title 49 (49 CFR).

REGULATORY INFORMATION FCC Compliance Statement: Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
