3. Ventilation of the 910 sT Console is accomplished by two blowers located on the bottom of the enclosure The filter on the inlet blower must be changed periodically depending on the ambient dust conditions The 910 sT Console must not be installed where the ambient air temperature will exceed 40 deg C some 910 sT System accessory components described separately do require special services or construction depending upon the application The standard 910 sT System herein described requires no special services Note that the Console has been wired to either 117 VAC or 230 VAC at the factory Supply wiring to the 910 sT Console Unit should be at least 18 AWG and run to the Unit in a manner in accordance with local wiring codes A mains circuit breaker is not required because the 910 sT Console Unit contains an internal overcurrent protective device It would be convenient for servicing and maintenance purposes however if a circuit breaker or disconnect switch was placed near the 910 sT Console Unit Power drawn by the 910 sT System does not exceed 120 VA The cables to the Sensor are shielded so it is not necessary to run them through conduit They should be routed so as to not be damaged during the normal operation of the process Cables will probably be run for the 4 mA gt 20 mA current output and or the LOP alarm switch It is not necessary to run these cables through conduit although it is recommended for protection purposes

P Signal can range from 0 to 4095 When the AGC is in its operating range the LOP will not exceed approximately 3500 The LOP Alarm values entered must also be in this range Note that a Cal Sig greater than 4000 can be prevented from generating an incorrect moisture result by entering a LO LOP value of 800 With the AGC controlling LOP at 3000 and since LOP operates on the High Heference peak or the Low Signal peak LOP Alarm will occur at a Cal Sig of 3750 by virtue of alarming at the Low Level of 800 The LOP Alarm condition freezes the moisture content output at the last value before LOP SMOOTHING CONSTANT The maximum Smoothing Constant which can be entered is 999 This corresponds to a Smoothing Time Constant of approximately 34 seconds Probably much too long for a practical installation 21 NOTES ON NUMERICAL VALUES USED IN 910 sT SYSTEM Continued 4 20 MA SCALING The entries for these factors are in moisture content The moisture values which can be entered here range from 0 0 96 to 99 99 96 A direct reading current display can be obtained over the range from 4 096 to 20 096 by entering 20 0 and 4 0 in the entry boxes When scaled this way if the moisture content exceeds 20 4 the current output will stop increasing DATAFILE The entry here is a standard DOS file name of up to eight 8 alpha numeric characters followed by nothing or a period and three more alpha numeric characters Pick a name which is related to the materi
14. T SYSTEM INTRODUCTION The 910 sT System has been configured for operation specifically as a Dry Moisture Measurement System Generally this covers a range from 0 0 96 to approximately 30 96 moisture content by the wet weight basis Consequently for best accuracy in this operating range certain restrictions are placed on the maximum value of the numerical values used in the System The 910 sT System has been evaluated with this configuration in the Wet moisture range from approximately 30 to approximately 65 moisture content wet weight basis The oystem will operate satisfactorily in this range but some materials may require that the math algorithms be changed to allow higher values of Cal Sig or other parameters for best operating results MOISTURE CONTENT The System will not permit moisture content values in excess of 99 99 to be entered It is the intent of this System that it be used primarily on materials which are calibrated on a wet weight basis If the calculated moisture content exceeds 100 00 percent the display will show only the rightmost four 4 digits Thus 104 5996 becomes 4 59 CALIBRATION SIGNAL This System will not permit values of Cal Sig exceeding 4095 to be entered in the Calibration Table The System will correctly generate Cal Sig values up to 6553 for use in the calibration math routines at which time the digital math routines will roll over and generate an incorrect output result LOSS OF PRODUCT The LO
