User's Guide _______________________________________________________________________ Wiring WARNING Connect only de-energized wires. NOTE 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.

Chapter 4 _______________________________________________________________ Maintenance CHAPTER 4 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 Do not attempt to clean contaminated INTERCAP® sensors or filters.
User's Guide _______________________________________________________________________ Replacing the INTERCAP® Humidity Sensor HMDW80 series transmitters use the Vaisala INTERCAP® sensor for humidity measurement. The INTERCAP® sensor is designed to be replaced when necessary, and does not require adjustment by the user. Replacing the INTERCAP® Sensor on Models HMD82/83 and HMW88/89 New INTERCAP® humidity sensor. New filter (always recommended when replacing the sensor).
Chapter 4 _______________________________________________________________ Maintenance Replacing the INTERCAP® Sensor on Wall Models HMW82/83 - REQUIRED TOOLS 1. 2. 3. 4. New INTERCAP® humidity sensor. Small flat head screwdriver. Use the screwdriver to push down on the tab on the top of the transmitter and open the transmitter cover. Remove the old sensor, and insert the new one. See Figure 21 below. Reconnect the cover to the mounting base.
User's Guide _______________________________________________________________________ Replacing the INTERCAP® Sensor on Outdoor Models HMS82/83 - REQUIRED TOOLS NOTE New INTERCAP® humidity sensor. New filter (always recommended when replacing the sensor). Medium size crosshead screwdriver (Pozidriv) Flat head screwdriver 3 mm hex key (Allen key) for opening the radiation shield screws.

Chapter 5 ____________________________________________________________ Troubleshooting 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. Probable Cause and Remedy 1. Models with probes: check if the yellow transport protection cap has been left over the probe.
User's Guide _______________________________________________________________________ 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.
Chapter 5 ____________________________________________________________ Troubleshooting Technical Support For technical questions, contact the Vaisala technical support by e-mail at helpdesk@vaisala.com. Provide at least the following supporting information: - Name and model of the product in question Serial number of the product Name and location of the installation site Name and contact information of a technically competent person who can provide further information on the problem.
