This information is necessary for theController to convert themeasurement into GPM. In theexample 917 pulses counted over 10seconds correspond to 250 GPM.The actual numbers depends on theflow sensor and the pipe size.

Pulse/10 seconds are mostly usedwith impeller type flow meteres.

ms/pulse (milli-seconds betweenpulses us used with sensors thatgive a small number of pulses persecond.

mA (4-20 mA) is an industrial type ofsensor.

If you check this box allflow measurements willbe logged in the monitorfile.

The test offers a choice of 3 voltagelevels for the testing.Test level 1 (15Volts) will search for only severeleakages as compared to test level 3(35 Volts) which will search for verysmall leakages.

Unless there are many and severeleakages it is recommended to startat level3. If there are many faults thetest should be repeatet afterrepairing the faults because manyheavy faults may cover up for theminor leakages.

Reprogramming

After selection of the test voltage thetest will start with reprogramming ofall decoders followed by a period of5 minutes where the two linees areautomatically connected togetherand supplied wotih the line voltage(of the level selected), with respect toground.

After the 5 min’s period the normalline voltage is applied again, and thetest “LD short” is run automatically.

During this rest all leaky positionaare displayed with measurementsresult on the screen . The threecurent values represent (as before)standby-, inrush- and holdingcurrents.

A given number of currentmeasurements will be made eachtime a decoder is tested. The timeinterval will set the time betweeneach measure taken. The value ofthe time interval is user definable andcan be set from 5 ms to 100 ms. Thedefault value is 20 ms. In ourexample you may verify the standby,inrush and holding to 34, 482 and 56mA.

21

The necessary instruments for servicing the irrigation system is a digitalvoltmeter and a clampmeter. If the voltmeter is used only to checkvoltages on the system, a resolution of 1 V is sufficient.

The clampmeter can be either a probe connected to a voltmeter or aseparate instrument. In the first case the voltmeter must have aresolution of 1 mV (AC). Observe that although the resolution is 1 mVthe accuracy is typically +/- 3 mV. The probe must have a resolution of 1mA. For the probe a conversion of 1 mA to 1 mV would be normal. As aseparate instrument, it is difficult to find one with a measuring rangedown to 1 mA. Most of these are designed for power applications andminumum ranges of 1 A are the usual. Normally clampmeters registeronly AC current but it is possible to get meters that register DC currentsas well, but those are more expensive.

A problem common to both the voltmeter and the clampmeter is thefrequency of the AC in the system. AC meters are normally designed forfrequencies from 50 Hz to 1000 Hz (mains frequency is 60 Hz). Thefrequency of the Flowmaster system is 1 Hz, but more about this inconnection with the individual measurements.

Line SurveyLine SurveyLine SurveyLine SurveyLine SurveyThis screen gives an overview ofvoltages and currents in the system.Values are updated every second,but not all at the same time. Thismeans that when values are varyingwith time, the readings shown on thescreen does not correspond.

This part contains Line current. Thelimit is the current where the voltageis reguylated down to preventoverload. The expected current iscalculated on basis of the nubmer ofLine Decoders in the installation database. The difference between singleand multiple Decoders is of courseconsidered.

The voltage is the Line voltagemeasured on the output of thecontroller. When the voltage dropsbelow the high threshold, the linepower is shut off. The low theshold isused when the Field Access unitcommunicates. The Line 1 and Line2 fields alternates red/green tosimulate the AC but are notsynchronized with the actual LineVoltage.

The graph on top showssequential method for our TESTschedule. Note that the total durationis 2:06.

Note thatthe total duration is 0:47. If there aremistakes in the flow data (too largevalve on too small pipe) the schedulewill not run! This method is of coursemore efficient than the sequential butstill has the advantage that the orderin which the valves are started is wellknown.

When the PROCOM Central unit is“Off line” (not in contact with yourPC), it still records events to memoryin the TWC-500. The recordings aretransmitted to the PC next time theyare “On line”. The TWC-500 canstore at least 2.500 lines.

The monitor window shows thename of the unit, action, date & timeand the flow total.

When the data treatment is finished,click on the Overview button on theFront Page to get the report osshown here. The report will showstart times and gallonage for theSchedules and eventual alarms.

If you want to check the deails of themonitoring, select from the “Excel”menu “data.xls”

This will open a window that listswhich valves were operatingtogether, the times and thecorresponding flows.

Notice that each Schedule has itsown sheet with a separate tag in thedata window.

Any of the monitoring sheets may beprinted from Excel in the usual way.

When you want to close the“Logviewer”, select “logviewer97-2000.xls and click the exit button. Allthe data sheets will automatically bestored when you exit this way.

SectorSectorSectorSectorSectorSectors are groups of Decoders thatshould be treated in the same way. Itis a tool to expedite data input whenyou set up an Irrigation schedule.

In this example a sector (BEDS) iscreated with 4 Decoders that willnormally run together and for thesame time.

Though a Decoder is included in asector it may still be included inschedules as an individual.

Select Display/Modify Sector. In theSector Edit window select the firstfield (with Total) and wirte the sectorname.

Now click on the Decoders field inthe “BEDS” line. This will open anew window, “Decoders display”

Click on the first field (Total) andwrite the name of the first Decoder.To add another Decoder, press<Enter> until the next field becomesselected and write the next name.

If you key in a non existing name,this message will occur.

Pump StatusPump StatusPump StatusPump StatusPump StatusThe pump status has three modes:

-Not installed-Active-Passive

The picture shows that only Pumps 1and 2 (with Pump Decoders) havebeen installed. Their status are now“Active”. This means that these twopumps will be used during irrigation.“Passive” means that a pump isinstalled, but is temporarily out ofoperation (for repair or mainte-nance). The system will correct forreduced pump capaicty duringirrigation. If you change the status ofa pump it will affect the time neededto carry out irrigation. It is thererforeadvisable to make a Dry Run.

Note that the status of pumps canonly be changed while the system isin Irrigation off mode.

Sensor StatusSensor StatusSensor StatusSensor StatusSensor StatusThe sensors status has three modes:

-Not installed-Used-Not used

If, for example, you want to preventyour Rain sensor from stopping theirrigation, it is not necessary todisconnnect it. Just change thestatus to “Not used”.

The table also shows when a sensorwas ON last time and when it wentOFF again. If a sensor is on whenyou select this function, no OFF timewill appear.
