INTRODUCTION1.1 Safety InformationThis manual contains information that must be observed in the interest of your safety and to avoid damage to assets. Please read this manual before installing and commissioning the device and keep the manual in an accessible location for all users.Contains FCC ID: W70MRF24J40MDMECaution: To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance operation at closer than this distance is not recommended. The antenna used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. No other antenna may be used with this equipment other than the PCB antenna supplied with this equipment.Please see the Certifications section for more information on RF Exposure Compliance 1.2 Hardware FeaturesThe IWPT range of Wireless Pressure Transmitters has been designed to measure the pressure of the medium connected and transmit the value to one of the IWR range of receivers where the value can be outputted as either a 4-20 mA or 1-5 V dc signal.The IWR-1 has a single output and the IWR-5 has five outputs, each of which can be linked to an IWPT transmitter. The IWPT pressure transmitter works on the license-free 2.4 GHz band.Ranges of up to 500 m are possible using the standard transmitter and receiver unit with the optional 3dBi antenna giving a range of up to 750 m. The transmitter is powered by a 3.6V lithium cell and care must be taken to insert the battery in the correct polarity.2. UNPACKINGThe instrument should be carefully inspected for signs of damage that may have occurred in transit. In the unlikely case that damage has been sustained, DO NOT use the instrument, but please retain all packaging for our inspection and contact your supplier immediately.3. PRODUCT IDENTIFICATION LABELThe unit delivered should be carefully inspected to ensure it is suitable for the application required. Detailed information on the product is included in the identification label and the user manual.Please ensure in particular, that the pressure range of the IWPT is suitable for the intended application and that the IWPT unit will not be subjected to pressures and/or temperatures greater than those specified in this manual.4.INSTALLING/CHANGING THE BATTERYA Lithium 3.6V battery is included inside the IWPT transmitter. The battery may be changed at any time but the correct polarity must be observed at all times! After the battery has been changed, the pushbutton SW1 should be pushed for 5s at the same time as the unit is switched on using SW3. This is to ensure the battery life count is set correctly when a new battery is installed.The internal LED will flash 5 times to indicate this procedure has been carried out successfully.The battery life is determined by the rate the transmitter sends the Pressure value to the receiver, this update rate can be selected using Dip Switch 1 and the default value is 10s. Please dispose of all batteries as specified by the legislator according to the Closed Substance Cycle and Waste Management Act or country regulations.! ! WARNING !MAKE SURE THE CORRECT BATTERY POLARITY IS OBSERVED!!! WARNING !INCORRECT BATTERIES MAY DAMAGE THE UNIT USE ONLY 3.6V LITHIUM C CELL BATTERIES5.1 Mounting InstructionsEnsure that:-- The instrument is used on a pressure medium that is compatible with the wetted parts- The correct seal is used and that the maximum torque (see below) is not exceeded- Fluid is not allowed to freeze in the pressure port as the diaphragm may be ruptured- No sharp objects are inserted into the pressure port as the diaphragm may be damagedTighten the unit in place using a wrench on the 18mm A/F hexagon provided on the unit. Ensure that no more than 15Nm is applied, that the system is de-pressurized, and that a suitable pressure seal is used.5.2 SETTING UP THE IWPT WIRELESS PRESSURE TRANSMITTERThe IWPT instrument is shipped in a default configuration which allows the unit to connect with any default IWR receiver unit and transmit the measured pressure every 10s simply by switching the unit on using SW3 on the internal circuit board.If a different update rate is required, or a different network frequency channel is required these parameters can be selected using DIP Switch 1 as detailed below:Switches 1, 2, 3 & 4 select the RF Network the IWPT will transmit on. The default network for both the IWPT transmitter and IWR receiver is network 1.

Install the unit into the pipework as required and switch the unit ON using SW3. Pushbutton switch SW1 can be pushed to force the unit to transmit its current pressure and LED 1 will flash twice if the transmission has been received and acknowledged by an IWR receiver unit.If the unit has transmitted successfully the 4-20 mA or 1-5 V dc output of the connected receiver unit will output a value reflecting the pressure level being measured.6.TROUBLE-SHOOTING GUIDEProblem encountered Possible CausesLED1 doesn’t flash when push button SW1 is pressed Unit not switched on, switch on using SW3. The battery is not installed correctly.The battery needs replacing.LED1 only flashes once when SW1 is pressed IWR receiver not switched on. IWR receiver is not set up for the same RFnetwork.IWR receiver not within range of the transmitter.If an IWR-1 receiver is used, ensure that the transmitter is set to Tx Channel 1Output from the IWR receiver isn’t equivalent to the Pressure being monitored IWR receiver set up incorrectly, see IWR user manual for further details.Check that the green external LED on the receiver is flashing when the transmitter push button is pressed as the receiver may be out of range.7.

(11)1 Overview Thermistors电热调节器简介1.1 General总则Resistance elements come in many types conforming to different standards, capable of different temperature ranges, with various sizes and accuracies available. But they all function in the same manner: each has a pre-specified resistance value at a known temperature which changes in a predictable fashion. In this way, by measuring the resistance of the element, the temperature of the element can be determined from tables, calculations or instrumentation. These resistance elements are the heart of the RTD (Resistance Temperature Detector or short: Thermistor). Generally, a bare resistance element is too fragile and sensitive to be used in its raw form, so it must be protected by incorporating it into an housing.电阻元器件满足不同的标准,能够适用不同的温度范围,可满足多种尺寸和精度要求。

Vent Line Sensor for Ammonia and Other RefrigerantsLinear 4/20 mA Output VL F7 N4 LPA M KUSERMANUALContentsSection PageDescription 31Sensor2Installation 53Operation 8Warranty 104LimitedSpecial CautionAlways assume that a relief valve can release at any moment. Always employ a “buddy” system, having help with you and watching what you are doing at all times. Always use safety goggles or a safety face shield, and always use gloves and have additional protective equipment easily available, including eye flushing equipment and a breathing apparatus.Personnel should be well trained and protected against falling if a sudden refrigerant leak startles the service person. Make sure there is always an escape route in case of a refrigerant release.IntroductionThis manual has been prepared to help in the use and installation of the Honeywell VL-F7-LPA Vent Line Sensor. This manual will convey the operating details of the sensor, ensure proper installation, and demonstrate start-up and routine maintenance procedures.This manual must be carefully followed by all individuals who have or will have the responsibility for using or servicing the sensor. Warranties made by Honeywell. with respect to this equipment will be voided if the equipment is not used and serviced in accordance with the instructions in this manual. If in doubt about a procedure, please contact Honeywell before proceeding.1 Sensor DescriptionFigure 1: Dimensions of the Vent Line Sensor and Pre-Amp2" N.P .T. pipe plug 7/8" diameter hole for 1/2"conduit electrical connectionThe Honeywell VL-F7-LPA Vent Line Sensor has a solid-state sensor imbedded in a 2" forged steel bull plug. A NEMA 4, 16 gauge steel box is fastened to the bull plug and houses a terminal strip. This is then wired to the current pre-amp which transmits a linear 4/20 mA signal to the readout equipment.The standard trip points are normally in the 5,000 ppm to 10,000 ppm range. Honeywell highly recommends that trip points be in this range due to the fact that minute amounts of a refrigerant released in the very small volume of a relief header will cause very high gas concentrations, normally in the percent range. Trying to have lower setpoints almost always results in false trips.The solid-state sensor used in this design must be considered “broad-spectrum,” i.e., it will detect many gases. Normally this is not a problem due to the higher setpoints commonly used.The sensors normally exhibit long life (five to eight years) unless exposed to very high gas concentrations for long periods or immersed in liquid refrigerant.Proper location in mounting the vent line sensor is the key to long and trouble-free life. Carefully reviewthe mounting instruction portion of this manual.Honeywell VL-F7-LPA Gas Sensor 1998M10501 Sensor DescriptionSystem SpecificationsMethod: Solid-stateRange:•Ammonia – 0 to 10,000 ppm (1%)•CFC/HCFC/HFCs – 0 to 1,000 ppm(depending on refrigerant)Output: Linear 4/20 mA – connects to all Honeywell readouts or other devices capable of accepting a 4/20 mA signalPower Requirements: Powered directly from Honeywell readouts or, when used as 4/20 mA pre-amp and sensor only, requires 17/24 VDC at 200 mA Operating Temperatures: –20° F to +120° F Enclosures:•Sensor – Aluminum NEMA 4•Pre-amp – Stainless Steel NEMA 4 Weight:• 3 lbs., sensor only•15 lbs., with mounting kitDimensions:•Sensor – 4 1/2" x 3 1/8" x 3 1/8"•4/20 mA pre-amp enclosure – 6" x 4" x 4" Cable Requirements:•Pre-amp to readout – #18/3 shielded cable (Belden #8770), maximum run length 1,500 feet •Sensor to pre-amp – #16 AWG, 4 conductors, non-shielded for runs up to 25 feet Specifications subject to change without notice.A Locating the VL-F7-LPAin a Vent Line SystemMount the Vent Line sensor 4-5 feet from the roofline and away from the discharge.See Figure 2 which shows where to mount the vent line sensor.Important mounting considerations:•Make sure discharge does not come down on top of sensor, i.e., hit the sensor or maintenancepersonnel when working on sensor.•Weld nipple to a vertical pipe.•Do provide a plug or means of inducing a draft through the vent header to remove residualrefrigerant after a leak. (Check with local codes tosee what is allowed in your area before doingthis.) Inducing an easy means of clearing theheader will help in troubleshooting a weepingrelief valve.•Safety – Always follow accepted industrypractice by using a face shield and gloves whenworking on the vent line sensor or any part of thevent line system. Always assume a relief valvecould release at any moment. Always treat ventline systems with extreme caution (see Figure 2).B Mounting the VL-F7-LPAin a Relief System VentingDirectly into a Water TankDue to numerous code requirements a common practice is to plumb vent line systems to discharge directly into a water tank. Even though this seems like a very simple and safe way to protect from atmospheric discharge, it presents some unique challenges to the refrigeration designer in assuring a safe relief system. It also presents challenges in where to mount the vent line sensor.The vent line sensor was developed over the years for monitoring atmospheric discharge of vent lines. When properly mounted as described in Section A, it is an extremely reliable method of detecting releases to the atmosphere.Figure 2: Mounting the Vent Line SensorThe advent of the water dump tank utilizing a standard water level covering the relief header discharge presents the vent line sensor with some unique challenges. There are several possible mounting locations as follows: •Water tank atmospheric vent. The simplest and most trouble-free method of mounting a vent linesensor is in this location. This location will not catchthe small weepers but only the larger dischargesresulting in NH3 vapor escaping from the water tank.This method requires no compressed air ventingand the resulting problems this can cause. To helpeliminate water condensation on the sensor, removethe 3/4" test plug to allow ventilation across thesensor (see Figure 3).•Mounting the sensor between the water seal and relief valves. After years of actual field experiencethis location has proven the most difficult. Therehave been occasions where the water has beensiphoned back into the vent header, completelyimmersing the vent line sensor and relief valves.Figure 3: Mounting the Vent Line Sensor whenusing a water tank atmospheric vent •Mounted with compressed air purge. The most successful systems have used compressed airventing into the header as shown in Figure 4. It isessential that this is dry air. Small compressorsdedicated to this have been marginally effective dueto the water condensed during the compressioncycle. It is essential the compressed air be dry inorder to help purge the complete vent line headerand also to compensate for the moisture migrationfrom the water seal. Process facilities that haveplant compressed air work the best when utilizing alarge dedicated dryer for the air injection.T he purge air will cause a small pressure to builddue to the water “head” of the tank. A water head of15 feet to 20 feet will cause the sensor to be 30 to40 percent less sensitive due to the higher airpressure. This is normally not a problem due to thehigh refrigerant concentrations needed for a tripcondition (see Figure 4).In summary, if at all possible mount the vent line sensor on the tank atmospheric vent and utilize a water monitoring method such as pH in the water tank. Figure 4: Compressed air purge system for theVent Line SensorC WiringFigure 5 presents wiring information for the VL-F7-LPA. Electrical wiring must comply with all applicable codes. Plant equipment that may be involved and operating conditions should be discussed with local operating personnel to determine if any special needs should be taken into account.Nearly all start-up problems are due to improper wiring or monitor configuration. Please follow these guidelines carefully.Between the current pre-amp and monitoring equipment use three conductor, #18 AWG, insulated, stranded, shielded copper cable. Between the vent line sensor and current pre-amp use #16 AWG, four conductors, non-shielded.Do not pull sensor wiring with AC power cables. Thiswill cause electrical interference. Be sure there are no breaks or splices in sensor wiring runs. If cable runs cannot be made without a splice, all connections must be soldered. Soldering should be done using a rosin flux to tie the connecting ends of sensor wires to ensure a positive and long-lasting contact.Ground the shield at the main control panel. Tape all exposed shield wire at the sensor to insulate it from the enclosure.All penetrations into a refrigerated room should be sealed to prevent condensate from forming in theconduit and dripping into the sensor enclosure. Silicone should not be used near the sensor, because silicone can damage the sensor.Make drip loops for cables going into sensor housings. Follow the mounting instructions on the Pre-Amp enclosure (…This End Up). See Figure 2.Electrical Power: 24 VDC regulated, 300 mA. Output: Linear 4/20 mA output corresponding to 0–1%.Monitoring equipment may have a maximum input impedance of 250 ohms.Cable Recommendation, Pre-Amp to Monitoring Device:#18/3 shielded cable (Belden #8770 or equivalent). Length of cable to pre-amp should be no greater than 1,500 feet. Use only the existing punched holes for connections to the pre-amp.Cable Recommendation, Vent Line Sensor to Pre-Amp:#16 AWG, 4 conductors non-shielded. Length of cable from vent line sensor to pre-amp should be no greater than 25 feet. Use only the existing punched holes for connections to the pre-amp.Monitoring: The VL-F7-LPA Sensor may be monitored by the Honeywell GM-JR, Air Alert 96D, or otherappropriately configured system. Monitoring equipment must be configured to indicate a fault if the signal is below 1.5 mA.A signal above 20 mA must be considered a high gas concentration.Figure 5: Wiring diagram for the Vent Line SensorBare Black Red (300 mA)WhiteA Start-Up Procedures Before applying power, make a final check of all wiring for continuity, shorts, grounds, etc. It is usually best to disconnect external alarms and other equipment from the sensor until the initial start-up procedures are completed.After power-up, allow 24 hours for the system to stabilize before testing the sensors. Because sensors are normally located at a distance from the main unit, thetest time required and accuracy of the response checks will be improved if two people perform the start-up procedures and use radio contact.Start-Up Test:•One person exposes each sensor to a small amount of the gas that is being monitored.•The second person stays at the control unit to determine that each sensor, when exposed to thegas fumes, is connected to the proper input andresponds, causing appropriate alarm functions. To do this preliminary check, there are two simplepossibilities:•Before installing the 2ft pipe, soak a small rag in “Parsons Ammonia Cleaner” and stuff this rag upthe 2" tee to expose the sensor.•After installation of the 2ft pipe, inject a small amount of propane/butane from an unlitplumber’s torch into the vent opening.Either of the above methods will work for the ammonia or halocarbon vent line sensor as they both use broad-spectrum sensors. Zero Calibration: After the unit is installed and has been powered up for a minimum of 24 hours, the unit should be zero calibrated by the following:•Be sure the unit is in clean air, or apply zero air at 0.8 L/min.•Adjust the zero pot until the sensor outputs4.0 mA (40 mV from Test [–] to Test [+]). Span Calibration: The unit is factory calibrated and normally does not need to be spanned. Do not adjust the span pot without certified calibration gas! If span adjustment is required, the following procedure will span the unit:•Perform zero adjustment before spanning •Apply span gas at 0.8 L/min (span gas must be in air, not nitrogen or other carrier).•After span gas has been on sensor for twominutes, adjust the span pot until the correctoutput is achieved.Calibration kits are available from Honeywell. Calibration of vent line sensors is normally done in the field by using the simple method described under “Start-Up Procedures” where the sensor is challenged with a gas and the proper outputs and trips are observed. (The challenge gas must cause a proper alarm trip.)In a vent line the recommended trip point level is between 15-18 mA. Lower setpoints can result in false trips. Never set alarm points higher than 20 mA.If certified gas samples are required, contact Honeywell for gases available and to discuss techniques in calibration depending on how the vent line sensor is mounted.Each Vent Line Sensor has been factory tested with a calibrated gas sample. Information is noted on the data sheet provided with each sensor.Due to environmental differences and background gases, the installed clean air signal may be different than it was during factory calibration. This difference can be zeroed out.B CalibrationC TroubleshootingSee the mounting instructions for proper mounting techniques.Contact Honeywell for more details if you cannot identify the problem.D MaintenanceHoneywell recommends that as a minimum eachsensor be challenged with a gas sample once each six (6)months.Also, the signal being sent by the sensor should be logged on a monthly basis.During the gas challenge test, all alarm outputs should be confirmed and logged to insure system integrity.E Replacement PartsFor replacement parts, contact Honeywell . Be sure to give serial number of unit.Figure 6: Troubleshooting the 4/20 mA Vent Line Sensor and Pre-AmpThe greatest probability for trouble is reversed orincorrect wiring. Always be consistent with color codes and double-check terminal screw tightness.If sensor output is 0.5 mA: The vent line pre-ampcontinuously monitors the status of the sensor and, if fault conditions arise, the red FLT LED in the pre-amp will light (see Figure 6). After a short time delay, the pre-amp will output a signal of 0.5 mA. Monitoring equipment must be configured to indicate a fault if the signal is less than 1.5 mA.First, check for proper color codes or loose wires to sensors labelled “O O R R” on both the pre-amp and vent line sensor.Second, if the FLT LED is lit continuously, remove the Vent Line Sensor junction box cover (see Figure 5). With power off, measure the resistance across the “RR” (Red Red) terminals which should be approximately 30 ohms. If this is an open circuit, a replacement sensor isrequired. Contact Honeywell . If the FLT LED is flashing, this indicates a faulty sensor. Contact Honeywell for a replacement sensor.If the sensor output is 0 mA: First, verify +24 VDC atthe sensor terminal block (see Figure 6, Note 2).Second, check voltage between Test– and Test+ (see Figure 6, Note 1). Voltage should be in the range of 40 mV to 200 mV corresponding to an actual current flow of 4 to 20 mA. If this voltage is 0 mV, the signal has no path to ground. Check monitoring equipment connections and configuration. Input impedance must be 250 ohms or less.If sensor output indicates a gas concentration when the vent line appears clean: Ensure the mud dauber screen is clear of debris. Cleaning the screen is essential for correct oxygen flow to the sensor. If the sensor is not responding correctly , remove the 2' vent pipe to apply gas directly to the sensor. Weeping pressure relief valves could be the problem. Always do the testing at the sensor with special caution as all vent line systems could discharge at any time. Always be prepared and wear appropriate protective gear such as a face shield and gloves.4Limited Warranty1.Limited WarrantyHoneywell Analytics, Inc.
