2.2 Transmitter Power Wiring

NOTE: Models 344 and 345 have the same motherboard (P/N 030-3564-00X), but have unique daughter boards. The 345 uses a daughter board (P/N 030-3565-001) that drives the 50 kHz Model 385-XXXX-XXX transducer, and the 344 uses a daughter board (P/N 030-3573-001) that drives the 38 kHz Model 384-XXXX-XXX transducer. Caution: DO NOT attempt to operate this unit at voltages other than as specified from the Model Identification as it will damage the unit. Caution: This instrument is grounded through the grounding con- nector of terminal block TB1. The power input must include a ground wire connected to a good earth ground. Failure to ground the instrument may allow a shock hazard to exist! 1. Open the cover of the transmitter enclosure by loosening the six screws. 2. The PC board is marked for 120/240 VAC (L1, L2/N, GND) and 24 VDC (+,–) power connections. Ensure proper con- nections are made on the six position terminal block TB1. Refer to Figure 14. Spade lugs should be used. For opti- mum operator safety, observe the wiring colors listed in the chart at left. 3. T o prevent electromagnetic noise from disrupting the normal operation of the Model 344/345, the ground (GND) should be connected to a good earth ground with as short a length as possible of heavy wire or copper braid. 4. Proceed to the appropriate transducer wiring section. NOTE: Stainless steel transducers are shipped with a protective rub- ber cap over the transducer face. Remove this cap after mounting is complete.

2.3 Transducer Wiring

Caution: Do not run transducer cable in the same conduit with power, signal, or other transducer cables. The transducer cable consists of two twisted pairs of wire wrapped with a shield. Refer to Figure 15 for wire identifi- cation. NOTE: It is imperative that Magnetrol cable part number 037-3176 (Belden Type 8102) be used. If connecting cable was not pro- vided with unit, consult factory for specifications. Maximum total cable length is 500 feet (152 m). AVOID SPLICING CABLE. If a 316 stainless steel transducer is used, connect the green ground wire to an earth ground (i.e. conduit, tank, etc). If a junc- tion box is used, connect earth ground to green terminal screw.

3.3 Operator Keypad

All Unit Configuration instructions in this manual will show the local transmitter display exactly as it will appear to the operator. The operator interface to the 344/345 is via a keypad consisting of the following keys: 17Echotel Model 344/345 Ultrasonic Non-contact Transmitter Password Sup Pass For numeric entry of parameters. For decimal-point entries. To exit any programming area and return to a measurement mode. For entering new parameter values into memory. Also used to exit the parameter entry mode, if pressed prior to entering numeric parameter values. To sequentially access other parameters. Parameters may also be skipped over without affecting their stored values. The DOWN arrow also acts as a backspace for correcting data entry errors.

5.7 Meas urement Range Calculations

U ltrasonic non-contact devices are typically rated for a ma ximum rang e in ideal conditions. Exp erience has shown that ma ximum range must be red uced for certain factors. Although the max imum rang e rating is somewh at conserv - ative, each application must be evaluated for specific con - ditions in the tank. H O W T O C A L C U L A T E To evaluate the performa nce of a 344 or 345 in a particular application, use the chart on the next page and follow the steps below: 1. Select one condi tion from each of the o perating param eters that best describes your app lication. 2. Enter the corresponding perform ance mu ltiplier value in the application co lumn. 3. M ultiply all of the selected values together. 4. Mu ltiply step 3 by the m aximum po tential range of the unit. This yields a value that is the m aximum allowa ble meas uremen t range for the ap plication. E X A M P L E The vessel is a closed-top tank, 26-feet tall and is filled from the top.

Operating Parameter Condition Performance Application Multiplier SURFACE AGITATION: Surface agitation or waves can degrade the Smooth, glasslike surface 1.0 performance. Moderate agitation results in only slight degradation Slight agitation, choppiness 0.9 of performance. The worst case is when the surface is a good Heavy agitation 0.8 reflector, but in the wrong direction. (See also transducer alignment.) Slight vortex (6°) 0.7 VAPORS AND STEAM: Vapors in the air space, above the process, become apparent, and cause problems when the liquid process No condensation 1.0 temperature is well above the temperature of the airspace. The greater the difference, the more expected vapor problems. The problems result from condensation or layering in the sound path, both of which attenuate the sound signal, degrading performance Little condensation 0.9 To avoid these problems, ensure that the vessel is insulated so that vapors are less likely to condense. If a vent is used, be sure that the Much condensation/ 0.8 vent, which is where condensation will form, is well away from the foggy appearance transducer. BEAM SPREAD INTERFERENCE: It is strongly recommended that No interference 1.0 nothing be allowed within the transducer’s beam, except the liquid which is being monitored. Often, the signal from the liquid will be Agitator at speed less than 60 RPM 1.0 strong, compared to the signal from other sources, such as ladder rungs, filling process material, support struts, etc. For that reason, Agitator at speed greater than 60 RPM Consult some applications may provide satisfactory results, even with Factory interference. Interference from agitator blades is only an intermittent interference that usually has little effect on performance. Interference outside 4°, far from 0.8 It is recommended there be no interference within the 6° half angle of transducer (in bottom third of range) the transducer beam. If interference is unavoidable, make the inter- ference as far as possible from the transducer so that the real signal Interference outside 4°, near to 0.5 at the longest distance is stronger than the interference signal. transducer (in top third of range) TRANSDUCER ALIGNMENT: Optimum performance is obtained when Beam perpendicular to liquid surface 1.0 the transducer is perfectly aligned. If the process is not perpendicular to the sound beam, the sound will not reflect properly back to the transducer. The effect is significant. Beam 4° off from perpendicular 0.5 FOAM: Even small thicknesses of foam can attenuate the ultra- No foam 1.0 sound and render the system inoperative. If possible, moving the Light froth, less than 0.25" thick 0.8 transducer to an area in the tank where there is less foam will improve the performance. Thick, heavy-density foams can sometimes produce Light foam, less than 0.5" thick 0.5 a reflection from the top of the foam. The multipliers shown at right Light foam, more than 1" thick 0.1 are general guidelines. For further assistance consult the factory. DUST: Dust attenuates the sound and results in poor performance. No dust 1.0 Even barely perceptible haze in the air can cause significant Haze, barely perceptible 0.7 attenuation. Slight dust 0.4 Heavy dust 0.1 AIR MOVEMENT: The movement of air, as possible in an open top No air movement 1.0 vessel, can create a layer from which the sound will reflect. This will Open vessel, but transducer below rim 0.8 be most noticeable in applications where vapors or steam tend to form. Open air movement in sound path 0.7 AMBIENT TEMPERATURE: The ambient temperature can have a -20° to +140° F (-29° to +50° C) 1.0 significant effect on the sound and on the transducer’s capability to -40° to -20° F (-40° to -29° C) 0.9 transmit and receive sound. The most noticeable effect on the transducer is at the temperature extremes. +140° to +160° F (+50 to +70° C) 0.9 PRESSURE: Sound requires air molecules to be able to travel. Sound -10 to +50 PSIG (0.689 to +3.45 Bar) 1.0 will not travel in a vacuum. Likewise, higher pressures will allow the sound to continue without decay, which can cause problems with Pressures outside above rating Consult multiple echoes.
