Chapter 2 ___________________________________________________________ Product Overview
Analog Output Overrange Behavior
Analog outputs of the HMDW80 series transmitters have a defined behavior when the values measured by the transmitter are outside the scaled analog output range: - Output is clipped at the end of the range. - Output is set to error state when measured value is 5% outside the
scaled range. See section Analog Output Error State on page 41.
- Output resumes normal function when measured value is back on the scaled range.
NOTE
HMW82/83 and TMW82/83 transmitters are different from the rest of the HMDW80 series. Their analog output is clipped at 10% outside the scaled range, and their analog outputs enter the error state when the measured value is 20% outside the range. For example, consider the temperature output of the HMD82 transmitter. The output is 4 ... 20 mA, scaled to -40 ... +60 °C (-40 ... +140 °F). - When measured temperature rises above +60 °C (+140 °F), the output rises to 20 mA and stops rising even if temperature rises further. - If the temperature rises above +65 °C (+149 °F), the output enters the error state of 3.6 mA.
NOTE
This overrange behavior does not mean there is a problem with the measurements, and it does not affect the readings shown on the display (if included in the transmitter model). The display always shows the currently measured readings if the measurement is operating without

CHAPTER 3
INSTALLATION
This chapter provides you with information that is intended to help you install HMDW80 series transmitters.
Selecting Location
When mounting duct model transmitters: - Avoid installing in a location where condensation may fall on the sensor inside the duct. - Position the sensor in the center of the duct. - Select a site where the transmitter can be installed horizontally, onto the side of the duct. When mounting wall model transmitters: - Select a location that represents well the area of interest. - Do not install on the ceiling. - Avoid placing the transmitter near heat and moisture sources, close to the discharge of the supply air ducts, and in direct sunlight. When mounting outdoor transmitters: - Install in a place that receives minimal direct sunlight. In the northern hemisphere, the North side of the building typically provides a suitable shaded location. - Avoid placing the transmitter near windows, air conditioning units, or other heat and moisture sources such as cooling towers. - Install the transmitter at least 2.5 m above ground level. 18 ___________________________________________________________________ M211510EN-E

MAINTENANCE
This chapter provides information that is needed in basic maintenance of HMDW80 series.
Cleaning
NOTE
The body of the transmitter can be cleaned by wiping with a moistened lint-free cloth. Do not use cleaning agents or solvents, or blow pressurized air into the transmitter housing or on the filter. Do not attempt to clean contaminated INTERCAP ® sensors or filters. Instead, replace them with new parts. Filters and sensors can be
purchased from Vaisala. For order codes, see section Spare Parts and Accessories on page 47.
Calibration
You can verify the performance of your HMDW80 series transmitter by comparing its reading with the reading from a portable reference instrument such as the HM70 Hand-Held Humidity and Temperature Meter. For operating instructions, refer to the documentation of your reference instrument. If the comparison indicates that the reading from the transmitter is not within specification, the transmitter may need to have its filter and sensor replaced.

CHAPTER 5
TROUBLESHOOTING
This chapter describes possible problems, their probable causes and remedies, and provides contact information for technical support.
Problem Situations
Table 7 Possible Problem Situations and Their Remedies Problem
Transmitter outputs an incorrect humidity reading. Temperature reading shown by the transmitter is too high. Current output on the temperature channel is ~24 mA. Analog output reading is unchanging and incorrect.
Probable Cause and Remedy
1. Models with probes: check if the yellow transport protection cap has been left over the probe. Remove it if present. 2. Models with configurable output parameter: check that the desired output parameter has been selected using the DIP switches. 1. The transmitter may be installed in an unsuitable location, for example, near a heat source or in sunlight. Use a portable reference meter to check this. 2. HMW82 and HMW83: Check that the transmitter is installed in proper orientation, with the arrow on the mounting base pointing up. Check that the humidity output channel is powered. Loop powered HMDW80 series models that have humidity measurement require that the humidity output channel is connected, even if only measuring temperature. The analog output channel may be in an
error state. See section Analog Output Error State on page 41.
40 ___________________________________________________________________ M211510EN-E
Chapter 5 ____________________________________________________________ Troubleshooting
Analog Output Error State
HMDW80 series transmitters set the output channel(s) into a defined error level instead of the measured result in two situations: - Transmitter detects a measurement malfunction. This means an actual measurement problem, such as sensor damage or unsuitable environmental conditions. - Measured value(s) are well outside the scaled output range. For a
more detailed explanation, see section Analog Output Overrange Behavior on page 17.
The error level depends on the output type: - For 0 ... 10 V output, the error level is
11 V
. HMW83 and TMW83 are an exception to this, their error level is
0 V
. - For 4 ... 20 mA output, the error level is
3.6 mA
.
The transmitter resumes normal operation of the analog output(s) when the cause of the error state is removed.
Error Messages on the Display
Table 8 Error Message
INTERNAL 1 INTERNAL 2 INTERNAL 3 ERROR HUM ERROR T
