The 607D housing is specifically designed to mount on a 35 mm DIN railin a panel. This mounting style allows for several units to be mounted closelytogether reducing required space. A wide range of models are available factorycalibrated to 0.25% full scale accuracy in ranges from the very low 0.1 in w.c. to25 in w.c. The zero control is for field calibration. Units also include red/green LEDstatus of proper transmitter operation. Versatile circuit design enables operationin 2-wire current loops.INSTALLATION1. LocationSelect a clean, dry mounting location free from excess vibration where thetemperature will remain between 20 and 170°F (-7 and 77°C). Distance from thereceiver is limited only by total loop resistance. See Electrical Connections below.The tubing supplying pressure to the instrument can be practically any lengthrequired, but long lengths will increase response time slightly.2. PositionA vertical position, with pressure connections pointing down, is recommended.That is the position in which all standard models are spanned and zeroed at thefactory. They can be used at other angles, but final zeroing must be done whiletransmitter is in that alternate position.Pressure ConnectionsIntegral barbed tubing connections are sized to fit 1/8˝ (3.12 mm) or 3/16˝ (4.76mm) ID tubing. Be sure the pressure rating of the tubing exceeds that of theoperating ranges.Model607D-01607D-02607D-03607D-04607D-05607D-06607D-07607D-08607D-11607D-12607D-13607D-14607D-15Range (in w.c.)0 to 0.10 to 0.250 to 0.50 to 10 to 2.50 to 50 to 100 to 250 to ±0.050 to ±0.10 to ±0.250 to ±0.50 to ±1Do not exceed specified supply voltage ratings. Permanentdamage not covered by warranty will result. This unit is notdesigned for 120 or 240 volts AC line operation. Electrical connections are made tothe terminal block located in front of the transmitter. Terminals are marked (+) and(-).NOTICEELECTRICAL CONNECTIONSWire LengthThe maximum length of wire connecting transmitter and receiver is a function of wiresize and receiver resistance. Wiring should not contribute more than 10% of thereceiver resistance to total loop resistance. For extremely long runs of wiring (over1000 feet), choose receivers with lower resistance to minimize size and cost ofconnecting leads. Where wiring length is under 100 feet, wire as small as 22 AWGcan be used.2-Wire OperationAn external power supply delivering 16 to 32 VDC with minimum current capability of30 mA DC (per transmitter) must be used to power the control loop. Shielded two wirecable is recommended for control loop wiring. If grounding is required, use thenegative side of the control loop after the receiver. It is not necessary to observepolarity of control loop connections.Wiring DiagramCalibration CheckEach Series 607D Transmitter is factory calibrated to the range given in the modelchart. To check calibration and adjust if necessary, the following procedure should beused. For purposes of clarification in these instructions, range is defined as thatpressure which, applied to the transmitter, produces 20 milliamps of current in theloop. Zero pressure is always assumed to be 4 milliamps except on bidirectionalmodels.1. With the transmitter connected to the companion receiver, insert an accurate multimeter in series with the current loop. The multimeter full scale range should be 30 mA or greater.2. Connect a controllable pressure source to one leg of a tee with the other two legs connected to the high pressure port of the transmitter and the third leg to an accurate test gage or manometer, in an appropriate range. The low pressure port should be vented to atmosphere. Calibration must be performed with the unit in the same position in which it will be mounted.3. Apply electrical power to the unit and allow it to stabilize for 10 minutes.4. With no pressure applied to the transmitter, adjust ZERO control so that loop current is 4 mA. Bi-directional zero pressure is 12 mA.Voltage OutputSeries 607D Transmitters can be easily adapted for receivers requiring 1 to 5 or 2 to10 VDC inputs. Insert a 249 ohm, (1 to 5 VDC) or 499 ohm (2 to 10 VDC) resistor ofthe proper power rating in series with the current loop but in parallel with the receiverinput. Locate this resistor as close as possible to the input. Because resistor accuracydirectly influences output signal accuracy, we recommend use of a precision ±0.1%tolerance resistor to minimize this effect.MAINTENANCEUpon final installation of the Series 607D Transmitter, no routine maintenance isrequired. The Series 607D is not field serviceable and should be returned if repair isneeded (field repair should not be attempted and may void warranty). Be sure toinclude a brief description of the problem plus any relevant application notes.
