Display

Display is present on the following models:
- HMD82D and HMD83D
- HMW88D and HMW89D
When the transmitter is powered on, it displays a sequence of information screens about the transmitter and its analog outputs. The screens are shown for a few seconds each. Checking the screens on startup is a good way to verify that the transmitter’s configuration DIP switches are set correctly.
1302-021
Figure 5 Startup Screens (HMD83D)
After the startup screens have been displayed, the transmitter will show the measurement screen.
1302-024
Figure 6 Measurement Screen (HMD83D)
If one of the transmitter’s error states is active, a notification symbol and error text will appear on the screen. Depending on the error, the affected measurement readings may be replaced by asterisks “*”. For more information on the possible errors, see section Error Messages on the Display on page 42.

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 42.
- Output resumes normal function when measured value is back on the scaled range.
NOTE
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.
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 error. For more information on transmitter errors, see section Error Messages on the Display on page 42.

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.

WARNING
NOTE
Connect only de-energized wires.
Transmitters with a configurable humidity output parameter use the marking HUM on the screw terminal labels. The default output parameter is relative humidity (RH) with output scaled to 0 ... 100 %RH, but the parameter can be changed using DIP switches. Changing the parameter also changes the output scaling. See section DIP Switches on page 30.

MAINTENANCE

This chapter provides information that is needed in basic maintenance of HMDW80 series.

Cleaning

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.
NOTE

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.

Error Message
Possible Cause and Solution

INTERNAL 3
Internal problem with the transmitter. Restart the
technical support if unable to remove the problem.
ERROR HUM
Humidity measurement failed. Check if the humidity sensor is damaged or missing.
ERROR T
Temperature measurement failed. Check if the temperature sensor is damaged or missing.

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 16.
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.
