PRODUCT OVERVIEW The HP and HN Series humidity sensors provide high accuracy humidity monitoring with a fully replaceable HS element for easy field maintenance. NIST certified accuracy and temperature sensing capability are available. The HP is a pendant style design, meant to be suspended from the ceiling. The HN is an insertion design meant to be mounted in a wall or other surface. Both are warranted for a period of five years.

TROUBLESHOOTING ProblemSolution Filter tip does not fit on probeHS element is backwards; reverse element. Unit reads approx. 4.5mAHS element is backwards; reverse element. Unit reads 100% with new replacement sensor Unit must be unpowered when installing a new sensor; interrupt sensor power to restart. Accuracy appears incorrect· Remove HS element while powered and verify output goes to full scale. · Verify voltage test leads on 4-20 mA models corresponds to the 4-20 mA output. SENSOR REPLACEMENT Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty. 1. Disconnect power to the unit. 2. Remove the probe from the junction box by loosening the black swage nut and sliding it out. 3. Unscrew the filter on the tip of the probe. Set filter aside. 4. Remove the HS element by gently pulling from the pin connector. Do not attempt to remove the temperature sensor adjacent to the HS element (if equipped). 5. Place a new HS element onto the pin connector. Orient as shown, or the unit will not function (the filter will not screw on if the HS is inserted incorrectly). Top Side Bottom Side Top Side Bottom Side Temp Sensor (if equipped) 6. Replace the filter. Re-insert the probe into the junction box and tighten the swage nut. Replacement HS Element Ordering Information HS2xxx Replacement 2% HS Element, Duct HS3xxx Replacement 3% HS Element, Duct HS4xxx Replacement 5% HS Element, Duct HS1Nx Replacement 1% HS NIST Element, Duct HS2Nx Replacement 2% HS NIST Element, Duct Replacement filters are provided with all HS elements. Order the appropriate element accuracy to match the motherboard accuracy for compatability. For 4–20 mA versions: Test leads output 0-1 VDC corresponding to 0 to 100% RH sensor reading. For example, a 0.42 VDC output on test points equals 42% RH sensor reading. These test points also provide an output that verifies the motherboard accuracy when the HS element is removed. Connect test point leads to voltmeter only. This output is not suitable for connection to a DDC panel. To check the motherboard functionality using the test leads, remove the sensor element. A 1.0 VDC reading verifies motherboard functionality. To verify sensor accuracy, de-power the unit and insert a replacement HS element. Repower the unit and compare readings to the original sensor. For example, if test points read 0.40 VDC (40% RH) with the original sensor, and 0.45 VDC (45% RH) with the replacement sensor, then the original sensor is 5% off specification. This method of ensuring accuracy offers more precision than using slings or other devices, and it eliminates the need to manually adjust sensors to an unstable standard. Note: Temperature, body sweat, and breath effect humidity. Ensure that conditions are stable to evaluate performance. The filter may be washed using warm water and a soft brush. Do not attempt to scrub the HS element. For 0-5V/0-10V versions, use the output as a test point and scale accordingly. Test leads and voltmeter verify accuracy and simplify DDC programming 1VDC 0.42 WHITE (+) GREY(--) Voltmeter shows reading of 42% RH TEST POINTS AND SETUP VERIFICATIONNext >
