US LISTED IND. CONT. EQ. 51EB GENERAL DESCRIPTION SAFETY SUMMARY PAXLIT 5 Amp AC Current Meter provides the capability of measuring large AC currents. The internal current shunt in the PAXLIT can measure up to 5 Amps AC current directly. Using an external current transformer, AC currents of up to 1,999 Amps can be measured and displayed. The PAXLIT can be scaled, using the scaling potentiometer, to display between 200 and 1999 when measuring full scale current. Using the DIP switch selectable decimal points, the display can be customized for direct readout for practically any application. The 3½-digit bi-polar display (minus sign displayed when current is negative) features a 0.56" high, 7-segment LEDs for easy reading. The meter is also available with custom units label capability. Using the PAX label kit (PAXLBK30 PAXLBK30), the selected label is installed behind the panel, keeping it safe from washdown or other environmental conditions. A DIP switch is used to control the backlight for the units label. The meters have a NEMA 4X/IP65 4X/IP65 sealed bezel and extensive testing of noise effects to CE requirements, allowing the meter to provide a tough yet reliable application solution. All safety related regulations, local codes and instructions that appear in the literature or on equipment must be observed to ensure personal safety and to prevent damage to either the instrument or equipment connected to it. If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

In extremely high EMI environments, the use of external EMI suppression devices, such as ferrite suppression cores, is effective. Install them on Signal and Control cables as close to the unit as possible. Loop the cable through the core several times or use multiple cores on each cable for additional protection. Install line filters on the power input cable to the unit to suppress power line interference. Install them near the power entry point of the enclosure. The following EMI suppression devices (or equivalent) are recommended: Ferrite Suppression Cores for signal and control cables: Fair-Rite # 0443167251 (RLC #FCOR0000 FCOR0000) TDK # ZCAT3035-1330A ZCAT3035-1330A Steward #28B2029-0A0 28B2029-0A0 Line Filters for input power cables: Schaffner # FN610-1/07 FN610-1/07 (RLC #LFIL0000 LFIL0000) Schaffner # FN670-1 FN670-1.8/07 Corcom #1VR3 Note: Reference manufacturer's instructions when installing a line filter. 5. Long cable runs are more susceptible to EMI pickup than short cable runs. Therefore, keep cable runs as short as possible. 6. Switching of inductive loads produces high EMI. Use of snubbers across inductive loads suppresses EMI. Snubber: RLC#SNUB0000 SNUB0000. WIRING OVERVIEW Electrical connections are made via screw-clamp terminals located on the back of the meter. All conductors should conform to the meter's voltage and current ratings. All cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that power supplied to the meter (AC) be protected by a fuse or circuit breaker. When wiring the meter, compare the numbers embossed on the back of the meter case against those shown in wiring drawings for proper wire position. Strip the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded wires should be tinned with solder.) Insert the lead under the correct screw-clamp terminal and tighten until the wire is secure. (Pull wire to verify tightness.) EMC INSTALLATION GUIDELINES Although this meter is designed with a high degree of immunity to ElectroMagnetic Interference (EMI), proper installation and wiring methods must be followed to ensure compatibility in each application. The type of the electrical noise, its source or the method of coupling into the unit may be different for various installations. Listed below are some EMC guidelines for successful installation in an industrial environment. 1. The meter should be mounted in a metal enclosure, which is properly connected to protective earth. 2. Never run Signal or Control cables in the same conduit or raceway with AC power lines, conductors feeding motors, solenoids, SCR controls, and heaters, etc. The cables should be run in metal conduit that is properly grounded. This is especially useful in applications where cable runs are long and portable two-way radios are used in close proximity or if the installation is near a commercial radio transmitter. 3. Signal or Control cables within an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other noisy components. 3.2 INPUT SIGNAL WIRING AC Terminal 1: VAC Terminal 2: VAC AC 3 AC Power 1 2 Current Signal (self powered) Terminal 4: + Amps AC Terminal 3: - Amps AC SIGNAL 3.1 POWER WIRING COMM 3.0 WIRING 4 - 115/230 A + 5A MAX. 4.0 SCALING THE METER FACTORY SCALING SCALING READOUT The meter is calibrated from the factory for 5 Amps AC current input to show 1999. This scaling will be used when the Scale Switch is in the "OFF" position. Place the Scale Switch in the "ON" position. This enables the Scale Potentiometer which is accessible from the back of the meter. (Enabling the Scale Potentiometer does NOT affect the calibration of the meter.) Place the Decimal Point Switches to the proper location. Apply the meter power and the current signal. Adjust the Scale Potentiometer to the desired value. This scaling only effects the span. There is no offset scaling. This means that only zero current can display a value of zero. At 5 Amps AC current input, the display can be scaled from 1999 down to 200 by using the scaling potentiometer. For display values below 200, turn on the appropriate Decimal Point Switch and then adjust the potentiometer to achieve the desired display value. Example: A customer wants to display 50 Amps because he is using a 50:5 CT. In this case, he must turn DIP switch 1 on for a decimal point and DIP switch 5 on for scaling. Then apply the 5 Amp signal and turn the scaling pot until 50.0 is shown on the display. 5 5.0 APPLICATION MOTOR CURRENT MEASUREMENT CURRENT TRANSFORMER USING A The PAXLIT 5 Amp AC Current Meter is configured by simply connecting the "COMM." (Terminal 3) and the "5AMP" (Terminal 4) to the external current transformer. The current carrying wire to be sensed is passed through the center of the current transformer. The resolution of the display, in this case, is 0.1 Amp, therefore, "Switch #1" is selected. The meter is now ready to be scaled. The installer has access to a calibrated portable digital current meter capable of measuring the motor current. Scaling will be accomplished by adjusting the scaling pot on the PAXLIT meter to agree with the portable digital current meter. The operator turns on the AC motor and lifts a large weight to load the motor. The installer then simply adjusts the scaling adjustment, located at the rear of the unit, until the display is equal to the value indicated on the portable current meter. The meter will now indicate the load current of the motor precisely. 115V/230V SCALE ADJUST 1 2 3 4 5 6 7 8 9 10 CURRENT TRANSFORMER 200 AMP/5 AMP RATIO AC CRANE MOTOR CAUTION: It is recommended that the current transformer be internally protected or that a voltage clamping circuit be provided, preventing dangerous high voltage across the CT secondary windings in case of accidental opening of the secondary output leads when the primary is energized. In order to prevent risk of electric shock ensure CT is installed according to local NEC regulations for installation of current instrument transformers. 6.0 TROUBLESHOOTING PROBLEM REMEDIES NO DISPLAY CHECK: Power switch and line voltage INCORRECT DISPLAY CHECK: Scaling adjustment pot DIP switch position ADJUST: Scaling pot VERIFY: Input Signal OVER-RANGE INDICATION VERIFY: Input signal For further assistance, contact technical support at the appropriate company numbers listed. 7.0 CALIBRATION The meter has been fully calibrated at the factory. Scaling to convert the input signal to a desired display value is performed by enabling the scale pot DIP switch. If the meter appears to be indicating incorrectly or inaccurately, refer to Troubleshooting before attempting to calibrate the meter. When recalibration is required (generally every two years), it should only be performed by qualified technicians using appropriate equipment. Input Calibration WARNING: Calibration of this meter requires a signal source with an accuracy of 0.05% or better and an external meter with an accuracy of 0.005% or better. Before starting, verfiy that the precision signal source is connected and ready. Allow a 30 minute warm-up period before calibrating the meter. Then perform the following procedure: 1. Set the DIP switch off to disable the scaling pot. 2. Apply half scale input signal. 3. Adjust calibration potentiometer as necessary for the display to read 1000 (ignore decimal point) 4. Apply zero signal and ensure display reads zero. 5. Apply full scale signal and ensure display reads 1999. 6 This page intentionally left blank 7 LIMITED WARRANTY The Company warrants the products it manufactures against defects in materials and workmanship for a period limited to two years from the date of shipment, provided the products have been stored, handled, installed, and used under proper conditions.
