2. _ AE Section 3 Installation This section provides information on installing the 3010 Flow Transmitter and ultrasonic level sensor USLS and describes connection of a 3010 to a sampler 3 1 General Comments on You can use the 3010 for portable or temporary installations Installation However you will generally make your installation permanent as you must connect the unit to a commercial power source You can install the flow transmitter either inside or out but inside installation is preferable particularly in areas with extremes of heat cold or moisture The flow transmitter is housed in a strong weather resistant plastic case but you should avoid installation where the case will be exposed to full sunlight This is particularly true in warm climates where it is important to prevent overheating the electronic components The flow trans mitter contains heaters to help maintain proper operating tem peratures for the electronics in severely cold weather 3 1 1 Location of the Flow The flow transmitter has a seal on the door and operation in wet Transmitter environments is permissible but never install the unit where there is any possibility of submersion This is not only harmful to the 3010 but there is also the possibility of electric shock from the presence of AC power inside the unit Always try to locate outside installations in relatively secure areas to min imize the possibility of tampering or vandalism Keep the
3. A CAUTION Do not transmit level or flow rate with event marks to any external equipment other than a circular or strip chart recorder Transmission of event marks causes momentary jumps of the 4 20 mA loop current to 100 full scale opera tion This will cause erratic operation of some process control equipment and could possibly have hazardous conse quences with certain equipment This output a variable DC current of 4 20 mA changes with the level or flow rate measured by the 3010 4 mA 0 flow or 0 level 20 mA 100 flow rate full scale or maximum head The 4 20 mA current output is a standard industrial control format It pro vides an analog variable signal to associated process equipment that must respond to the changing conditions measured by the flow transmitter The operation of such equipment is like a lamp controlled by a dimmer You can make the lamp can burn at many levels of brightness between fully off and fully on Compare this with equipment that is either on or off Step 18 Adjust Level This step allows you to adjust the measured level for the 3010 Acceptable values range from 1 to 12 5 feet 0 304 to 3 81 meters There are various ways to cali brate the level sensor after you have installed it depending on the primary device used Make your measurement from the zero level point of the primary device to the surface of the flow stream very carefully to determine the level in the flow stream Co

Teledyne Isco strongly rec ommends you call our Teledyne Isco Customer Service Department at 800 228 4373 or 402 465 3022 outside the U S A The customer service department will advise you how to return the 3010 to the factory Due to the complex nature of microprocessor based circuitry specialized knowledge and instrumentation are required for troubleshooting The Teledyne Isco service department has trained technicians and spe cially designed equipment necessary for timely efficient repairs If you still wish to attempt repairs the Teledyne Isco Technical Service Department is available to provide advice and infor mation on servicing Servicing circuitry controlled by a microprocessor is difficult when the program that controls it is not understood completely especially when there is no way to know whether the micropro cessor and memory are good Therefore when attempting to isolate problems within the unit assume the CPU and memory are working properly until you have exhausted attempts to find problems in the rest of the circuitry We advise you to do this for two reasons first the likelihood of failure is far greater on tran sistor drive circuits heavier currents pass through here than on the CPU or memory Second it is doubtful that the repair facility would have the time or equipment to do worthwhile trouble shooting beyond changing components on the CPU or memory Following are suggested areas to check before attem
10. The purpose of this program step is to provide signals to the sampler to run its own program The range is from 0 to 9 999 pulses per hour Determine this number the same way as in Step 9 previously Note that selection of the number of flow pulses to the sampler per hour is based on flow rate at maximum head so the actual number of pulses per hour will probably be consid erably lower Determine the number chosen by the volume of flow that must pass through the primary device before a sample is taken rather than a particular interval of time For example assume the flow rate at maximum head for a par ticular installation is 32 540 GPM 32 540 GPM x 60 min hr 1 952 400 gallons per hour GPH 3010 Flow Transmitter Section 2 Programming We want to send a flow pulse to the associated sampler every 10 000 gallons 1 952 400 GPH 10 000 gallons per pulse 195 pulses per hour You would then enter 1 9 5 If you programmed the associated sampler to take a sample every 50 pulses it will take a sample every 500 000 gallons 10 000 gallons per pulse x 50 pulses per sample 500 000 gallons per sample If you programmed the sampler to take a sample every 200 pulses it will take a sample every 2 000 000 gallons 10 000 gallons per pulse x 200 pulses per sample 2 million gallons per sample Steps 11 to 15 Plotter Output You only need to program these steps if your installation includes an Isco Model 2312 Plotter or other

The Flow Transmitter circuit board contains CMOS semicon ductors which are easily destroyed by the discharge of static electricity Do not attempt to make repairs at the job site Return the board to the factory for servicing or make repairs at an appropriately equipped service area See also Section 5 6 5 With the lower section of the cabinet open you can change the fuse The fuse is located on the Terminal PCB on the left side of the board It is visible when the protective cover is off See Figure 1 3 The fuse is labeled F1 The proper size for this fuse is 4 2 amp Slow Blow Always replace a blown fuse with one of the same rating Using a larger fuse could cause serious damage to the flow transmitter and could even cause a fire hazard by burning up the transformer if there is a severe short on the sec ondary Remove the power before changing the fuse If the new fuse blows immediately after power is restored there is a serious problem Either have qualified personnel repair the flow trans mitter or return it to the factory for repair The 3010 LCD displays various error messages to warn the user of problems in the program or difficulties inside the flow trans mitter Messages will generally assume the format of X represents a E XX number or numbers from 1 to 80 As mentioned in Section 2 a message of EE 80 indicates a failure to detect a return echo A message of EE 19 indicates that the temperature probe in the ult
