4. The mV signal then passes through custom linearization and conditioning circuitry The resulting signal is an industry standard 4 20 mA This mA signal is factory set over the specified range of the unit From here the signal may be sent to an Anderson digital display Microprocessor based controller chart recorder or customer supplied instrumentation Section 3 Installation The physical installation is the most important concern with regards to promoting sensor reliability Sensors must be installed in such a way that the housing and cable are not subject to physical abuse In addition moisture or moist air must not be allowed to enter the sensor housing or cable NOTE The installer assumes responsibility for preventing water or water vapor from entering the sensor housing Your new HA transmitter is supplied with a conduit housing If mounted horizontally the conduit connection should point downward Also to prevent entry of excessive moisture it is highly recommended that flexible conduits not be connected directly to the sensor If conduit is to be run to the sensor it is preferable that the watertight connector provided with each sensor not be removed from the sensor Instead run the flexible conduit as near to the sensor as possible and utilize a seal tight connector at the end of the conduit Allow a short amount of cable to run between the sensor and the flexible conduit This isolates the sensor housing from the conduit system

6. adjust at atmospheric zero If transmitter is a compound range you should be as close to sensor zero as possible You must calculate the expected mA signal use formula proved at start of this section 2 Remove cap from transmitter 3 With your meter set to DC mA connect the RED Meter lead to the TP terminal Connect the BLACK Meter lead to the TP terminal See Figure 2 4 Adjust the transmitter ZERO potentiometer as shown in Figure 2 until you either see 4 00 mA if you are at atmospheric zero or your expected mA signal for a compound range 5 Expose the transmitter to a know process variable near the top end of the range 6 Again using the formula provided calculate the mA reading expected 7 Adjust the transmitter SPAN potentiometer as shown in Figure 2 until you see your expected mA output NOTE For pressure transmitters with compound ranges the ranges must first be converted to all one type unit of measure For example a 30 Hg 0 30 psig unit may be considered to have a range of 14 7 psig 0 30 psig and a span of 44 7 psig 2 036 Hg 1 psi Be careful not to lose the sign while performing the calculation of the proper reading Section 7 Troubleshooting 7 1 VOLTAGE CHECK Using a digital multimeter on the DC volts scale and with the sensor connected to the re ceiver confirm that the sensor is being provided the correct loop power Place the RED Meter lead on the Loop terminal
7. and any moisture it may contain If the conduit is connected directly to the sensor the chances are high that the sensor will eventually fail due to exces sive water or water vapor entry into the housing NOTE It is recommended that a sensor ZERO be performed at time of installation Refer to section 6 1 for information on this procedure PAGE 5 PAGE 6 Section 4 Sensor Wiring Anderson recommends a cable of 24 gauge 4 conductor shielded Belden 9534 or equivalent Four conductor cable is utilized because of its roundness which provides a suitable seal when used with seal tight connectors strain reliefs and rubber grommets Irregular shaped cable does not allow for a watertight seal If utilizing customer supplied cable select a round cable with 22 24 AWG wire and a shield In order for the Anderson provided seal tight connector to seal on the cable the O D of the cable must be between 3 16 and 1 4 smaller cable is utilized a different neoprene bushing must be used must be customer supplied If an alternate seal tight type connector is going to be used be absolutely certain that the rubber bushing will adequately seal on the cable Do not use a connector intended for power cable large inside diameter if the sensor cable is only 1 4 Be sure to use Teflon thread tape when attaching the new seal tight connector Wiring to the conduit housing sensor is accomplished as follows 1 Remove the housing cap to expose t
8. and the BLACK Meter lead on the Loop terminal You should see between 10 40 VDC for a standard transmitter 7 2 CURRENT CHECK To check the mA loop be sure the sensor is connected to the receiver Open the cap on the transmitter to expose the wiring terminals Using a digital multimeter on the mADC scale connect the RED Meter lead to the TP terminal and the BLACK Meter lead to the TP terminal You will be reading the mA current loop A high current flow approaching 30 mA indicates a problem with the transmitter internal short If no current flow is observed this indicates either an open loop or a problem with the transmitter To check a transmitter at a know pressure refer to the Calibration section for information on how to properly calculate the mA output at the known value 7 3 NISCELLANEOUS TROUBLESHOOTING Symptom Action When testing Loop NO current flow Check for broken connections detected Check loop wiring incorrect polarity affects loop Feel free to contact Anderson Technical Services Department at 1 800 833 0081 for further assistance with troubleshooting PAGE 9 PAGE 10 Section 8 Warranty and Return Statement These products are sold by The Anderson Instrument Company Anderson under the warranties set forth in the following paragraphs Such warranties are extended only with respect to a purchase of these products as new merchandise directly from Anderson or from an Ander
