Push one end of the clear flexible PVC (vinyl) tube to the tapered end of the intake strainer, until the tube is within 0.635 cm (¹ in.) of the solid white Teflon strainer body.142. Push the other end of the vinyl tube on to the stainless steel fitting connector end that points away from the pump control housing.143.4.2 Teflon-Lined Polyethylene Intake Line141. Place the stainless steel hose clamp over the stainless steel fitting until it abuts the shoulder of the tubing connector. Secure with a tubing clamp.142. Push the stainless steel fitting into the Teflon-lined tubing until it abuts the shoulder of the stainless steel fitting.143. Slide the stainless steel hose clamp over the silicone tubing, then push the silicone tubing over the stainless steel fitting on the liquid sensor.144. Slide the tubing clamp over the silicone tubing until it is over the stainless steel fitting on the liquid sensor. Tighten to secure.155. Repeat the procedure for the intake strainer.153.5 Setting Up the Intake Line and Strainer153.6 Choosing Bottles153.7 Installing the Full Bottle Shut-Off15Figure 5 Full Bottle Shut-off161.

The external flow meter must provide a dry contact closure.184-20 mA Input18Note: Older model 4-20 mA interfaces (Cat. No. 913) require correct loop polarity to properly work. The newer generation (Cat. No. 2020 series) interfaces are not sensitive to loop polarity.18Figure 6 4-20 mA Interface and Pulse Duration Input19Splitter Interface19Figure 7 Splitter Interface19Section 4 Operation214.1 Keypad and Key Functions21Figure 8 Front Panel224.2 Tips and Techniques for Programming the Instrument224.3 Setting the Time and Date23Note: When setting the time and date, the * key causes the display to back up to the previously flashing character.231. Check the real-time clock and date settings by pressing TIME/READ. The display will show the time and date for several seconds: 10:35 AM 24OCT00232. If the time or date are not correct, press TIME/SET. The time and date will appear on the display, with the hour flashing.233. Press the appropriate numerical key(s) for the correct hour. When the correct hour flashes on the display, press YES. This will cause the minutes to flash on the display.234. Using the same procedure, select the correct minutes and press YES. The am/pm indicator will flash.235. If the desired indicator is flashing on the display, press YES. If the desired indicator is not flashing, press NO. This will cause the other indicator to flash.236. Press YES. The month will begin to flash. Select the correct day, month and year using the same procedure as you used to set the time.237. After the correct year has been entered, the display will read "Synchronize Time-enter at Time". Pressing YES will start the clock. The display will read "Clock is Now Set".234.4 Bottle Setup Mode231. With the sampler in standby state, press the * key. The display will read “Enter units for bottle volume, milliliters?”.232. Press NO to cause other volume units to appear. When the desired units appear on the display, press YES.233. The display will show "Volume = _ _ _ _ _ mL" (or "Volume = _ _ _ _ _ Gallons"), whichever was chosen in the previous step.234. Enter the volume for the individual sample bottle by pressing the numerical keys.235. Press YES to accept the volume.234.5 Explanations of Program Messages244.6 Data Logging251. To access information, the sampler must be in the "Program Halted" or "Program Complete" standby state.252. Press TIME/READ for two seconds. The display will read "Samples Taken".253. To display the time/date for each sample, press YES. To advance to the next sample time/date, press YES again-and so forth, until all are given.254. To exit this routine, press NO. The time and date of any missed samples are displayed after collected samples.254.7 Manual Mode254.7.1 Manually Operating the Sample Pump251. To manually operate the pump, place the sampler in standby state. The sampler is in standby state when the display reads "Ready to Start", "Program Halted", or "Program Complete".252. To operate the pump, press either the PUMP or PURGE key. This will cause "Manual Mode - Pump/Purge/Clear" to appear on the di...253. To run the pump continuously in either direction without having to hold down the PUMP or PURGE keys, press the * key. This will cause "Lock-Pump/Purge" to appear on the display. Then press either PUMP or PURGE.254. To stop the pump, press STOP PUMP or turn the sampler off with the OFF key. Pressing STOP PUMP returns the display to "Pump/Purge/Clear".255. To exit the manual mode, press CLEAR ENTRY. This returns the sampler to the standby state.264.8 Measurements Triggered by Liquid Levels or Flow26Mode 126Mode 226Mode 3264.9 Programming the Sampler for Level Control274.10 Other Displayed Messages274.11 Flow Proportional Operation284.11.1 How to Calculate Pulses/Counts284.11.1.1 Flow Proportional Sampling Intervals-Using External Pulses281. Determine f, where f represents the flow increment between samples and n represents the total number of samples to be collected.282. Multiply the flow increment between samples, f, by the pulse frequency output of the flow meter (i.e. 1 pulse per 100 gallons...28Example 1281. Determine the flow increment between samples:282. Multiply the flow increment, f, by the pulse frequency output of the flow meter.28Example 2281. Determine the flow increment between samples:292. Multiply the flow increment, f, by the pulse frequency output of the flow meter.29Example 3291. Determine the flow increment between samples:292. Multiply the flow increment, f, by the pulse frequency output of the flow meter.29Flow Proportional Sampling, External-Using 4-20 mA Signal Converted to Pulses, Flow Signal Interface291. Calculate Q, where Q is the average flow rate (during the sampling program) divided by the maximum flow rate. (The maximum flow rate corresponds to the 20 mA output of the flow meter.)292. Calculate t, where t is defined as a/n; n is the total number of samples collected over a given period of time; and a represents time in minutes, over which n samples are collected.293. Multiply Q x t. Enter the result in the programming step: INTV = _ _ _ _ CNTS.29Example 1301. Calculate Q.302. Calculate t.303. Multiply Q x t.30Example 2301. Calculate Q.302. Calculate t.303.

Turn the unit off by pressing the OFF key.332. Disconnect and remove all cables to the controller housing, including the distributor/full bottle shutoff cable.333. Disconnect all tubing.334. Place the controller, face down, on a cloth-covered workbench to prevent scratching the front panel.345. Inside the Center Section, remove the four screws that fasten the Controller.346. Lift the Center Section off the controller.347. Remove the 17 screws from around the perimeter of the controller back panel.348. Carefully pull open the bottom panel and let the attached connectors swing out of the way.349. If necessary for the repair being performed, unplug the appropriate connectors. Always note each connector location before unplugging anything. Re-installing a plug into the wrong connector can cause extensive damage.345.7 Re-installing the Bottom Panel341. Hand tighten each nut until it makes contact with the panel.342. Tighten the nuts in sequence shown in Figure 9 to 5 in.-lb (0.56 N-m).343. Repeat the tightening procedure in the same sequence to 10 in.-lb (1.13 N-m).34Figure 9 Tightening the Nuts on the Bottom Panel345.8 Internal Desiccant Module355.9 Circuit Board Identification35Figure 10 Circuit Board Description351.
