5.0 SETUP & INSTALLATION The installation of the SmartDRY™ Cabinet may be performed by the end user. Local, city, county, or other ju- risdictions may govern the use of this equipment. If you have any questions about local requirements, please contact the appropriate local agency.
5.2 LOCATION When selecting a site for the cabinet, consider conditions which may affect performance, such as heat from radiators, ovens, production equipment, etc. Avoid direct sun, fast-moving air currents, heating/cooling ducts etc. To ensure air circulation, allow a minimum of 75 mm (3”) between the unit and any walls or partitions which might obstruct free air flow.
5.3 LIFTING / HANDLING SD Series Dry Cabinets are heavy and care should be taken to use appropriate lifting devices that are suffi- ciently rated for the load. SD Series Dry Cabinets should only be lifted from their bottom surfaces. Door han- dles, enclosures and cabinet overhangs are not adequate for lifting or stabilization.
5.5 SHELF PLACEMENT Cabinet Shelves are held in place on each side by a shelf support that slips into pre-cut slots. The shelf sup- ports are symmetrical and can be used to support either the left or right side of the shelf. Slots are pre-cut to prevent blocking of air vents and LED lighting in addition to fitting most common parts bins, boxes and reels;...

10.2 ECD SMARTDRY™ HUMIDITY AND TEMPERATURE SENSOR This sensor is a highly accurate environmental sensors. Exposing the sensor to the following can cause drift of the humidity reading – irreversibly in most cases. The list below are examples and do not represent a com- plete list of possible harmful substances, but are the most common used in electronic manufacturing.
10.3 CLOCK BATTERY The real time clock is battery backed and will require replacement at least annually or more often if there have been long or total accumulative power outages. To change the battery please follow these steps: 1) ALWAYS disconnect the cabinet from the power cord from the power supply before replacing the bat- tery.
10.4 SMARTDRY™ DRYER The SmartDRY™ Dryer module should last for many years and yet is designed to be replaced, should damage occur or a component fails. SmartDRY™ will warn if a Dryer loses it's effectiveness for any reason. PRIOR TO DRYER REPLACEMENT, THE VERSION OF DRYER MODULE THAT IS INSTALLED ON YOUR CABINET MUST BE IDENTIFIED.

Step 3 - Final Assembly: 1) Replace the top cover: • Lower the top cover and connect light tower option to J5 on Power Board, if included.
The RH/Temperature probe should be calibrated on a regular basis. A good calibration schedule is annually, however your calibration practices may be different. The probe can only be calibrated by ECD and can be eas- ily removed and returned. Because the calibration information is kept internal to the probe, a replacement probe can be purchased and “swapped”...

APPENDIX E: GOSSARY Relative Humidity (%RH): The amount of water vapor currently in the air divided by the maximum amount of water vapor the air could hold at that same temperature multiplied by 100, expressed in percent. Cold air cannot hold very much water vapor, and hot air can hold much more.
Page 89
Table shows the amount of water in grams per cubic meter and the dew point over a range of relative humid- ity and air temperature. AH in g/m3 and Dew Point ºC given RH and Air Temp SD Series Dry Cabinets Setup and Operation Manual | A55-7379-00 Rev: 2.0.0 Page 89...
Page 90
Absolute Humidity (AH g/m^3): The mass of water vapor, in a given volume of air, at any temperature, typically expressed in grams per cubic meter. This means it does not matter how hot the air is, the amount of water vapor in a fixed volume of air does not change.
Page 91
Dew Point: The temperature value at which the air can no longer hold the amount of water vapor it contains and the wa- ter vapor (gas) begins to condense out and form water droplets or dew. This measurement is useful in predict- ing the weather since it highlights at what temperature dew as fog or rain will occur given the current relative humidity and the expected low temperature overnight.
Page 92
Relative Humidity Sensors: There are two basic types of humidity sensors: mechanical and electrical. Both require precise measurement of one or more temperature values and, depending on the type, some other electrical property of the sensing element or physical parameter like barometric pressure. Here are some of the most common methods for rel- ative humidity measurement: •...
Page 93
Wet Bulb, Dry Bulb (AKA: Psychrometer): The name of this method is derived from the spinning of two thermometers through the air to take advantage of the wind chill effect on one verses the dry temperature on the other. One of the older procedures for calcu- lating humidity, this technique measures two temperatures, one from a wet bulb and one from a dry bulb.
Page 94
The current barometric pressure also has a small effect on the results so, to refine the result, measure the pressure and enter it into the %RH equation 14 where P is the pressure in kiloPascals (kPa), Td is the dry bulb temperature in ºC and Tw is the wet bulb temperature in ºC and e is the “natural”...
Page 95
Polymer Capacitive Sensor: The most popular relative humidity electrical sensor, this device actually changes its capacitance as a function of Relative Humidity, about 0.2pF to 0.5pF per 1%RH. Again, the manufacturer provides details on converting this capacitance change to %RH. Polymer capacitive sensors are very dependent on the temperature; however temperature is one of the easiest measurements to take, so this does not present any issues.
APPENDIX F: NETWORK Dashboard: 1) Data Graph: Crosshair - The Data Graph displays a line connecting the points with their corresponding axis. Range Selector: The range selector is a tool for selecting ranges to display within the chart. It pro- vides buttons to select preconfigured ranges in the chart (1, 3, 6 month etc).
