DIN RAIL AMPLIFIER, MWI-13262 ULTRA SERIES 2.6 MAN-13262 ULTRA REV BA POTENTIOMETERS In addition to the Gain and Zero adjustable Potentiometers visible on the front of the unit, there are adjusts you can make by removing the snap-off cover on the side of the amplifier. The adjustments are on the output and input printed circuit boards as shown in Figure 4.
DIN RAIL AMPLIFIER, MWI-13262 ULTRA MAN-13262 REV BA 2.9 GAIN SELECT SWITCHES The group of jumper-switches that control the fixed gain of the Instrumentation Amplifiers (IA) are located closest to the front left edge of the Input card. (Refer to Figure 4) Typically, you configure both channels to the same setting if both transducers are the same force rating.
DIN RAIL AMPLIFIER, MWI-13262 ULTRA SERIES 2.12 MAN-13262 ULTRA REV BA WIRING Most start-up problems are the result of mis-wiring or failure to reference the detailed information in this manual. While a convenient basic wiring diagram can be found printed on the side label of the amplifier case, the diagram is intended only as a helpful guide when checking field wiring.
DIN RAIL AMPLIFIER, MWI-13262 ULTRA MAN-13262 REV BA 2.13 THE POWER SUPPLY For best performance a regulated power supply should be used with the Ultra Series DIN Rail amplifier. It is important that you pay particular attention to the power supply for susceptibility to the effects of conducted and radiated energy from noise sources. Every effort should be made to provide stable voltage to the amplifier using correct wiring practices and filters. To protect against circuit damage, include a 0.
DIN RAIL AMPLIFIER, MWI-13262 ULTRA SERIES MAN-13262 ULTRA REV BA 2.13.2.1 4 TO 20 MA ANALOG CURRENT LOOP The 4-20 mA current loop output is undamped and can be used concurrently with the other outputs. The 20 mA current level corresponds to the +10V output. The 4 mA level corresponds to 0 volts on the 10V output. This output does not have an individual Gain and Zero Potentiometer adjustment.
DIN RAIL AMPLIFIER, MWI-13262 ULTRA MAN-13262 REV BA 2.13.2.2 APPLICATION INTERFACE DETAILS The 4-20 mA output stage is designed to drive a loop current through a floating burden resistance. Examples of driving a loop current through a floating burden resistance include: a loop powered 4-20 mA display or, the isolated input of receiving electronics (isolated Analog to Digital input).

DIN RAIL AMPLIFIER, MWI-13262 ULTRA MAN-13262 REV BA 2.13.2.4 DAMPED +/- 1 MA ANALOG The meter output stage can be configured to operate as current output (sinking or sourcing current depending upon output polarity). It can be used concurrently with the other outputs. It does not have an individual Gain and Zero adjustment, necessitating that a compromise be made during calibration, or a particular output be favored (over one that can accommodate external scaling and offsetting).
DIN RAIL AMPLIFIER, MWI-13262 ULTRA SERIES 3.1.2 MAN-13262 ULTRA REV BA POWER APPLICATION Apply DC power to the amplifier and use a DC voltmeter to confirm that the supply polarity and voltage is within the prescribed limits. As soon as is practical, confirm that the excitation voltage is either 5.0 VDC or 10.0 VDC as appropriate for the type of load cells being used. Promptly identifying any over-voltage condition can help minimize potential damage to the strain gage elements internal to the transducer.
DIN RAIL AMPLIFIER, MWI-13262 ULTRA MAN-13262 REV BA 3.4 APPLYING FORCE TO TRANSDUCERS The application of an accurate calibration force can be a challenge. Keep the following points in mind: 3.5 • The test force should be a moderate percentage of the intended working force of the transducer, and never over the 100% Mean Working Force (MWF) or you may risk calibrating with an overloaded (“clipped”) transducer signal.
DIN RAIL AMPLIFIER, MWI-13262 ULTRA SERIES 3.6 MAN-13262 ULTRA REV BA ADJUSTING AMPLIFIER COURSE ZERO Two individual coarse offset adjustments have been provided. There is an adjustment for each Instrumentation Amplifier channel because each transducer can have unique offset voltages. Keep in mind that the Coarse Zero adjustments are usually only adjusted one time, typically when the amplifier is installed, or transducers are replaced. 1.
DIN RAIL AMPLIFIER, MWI-13262 ULTRA MAN-13262 REV BA 3.8 GAIN AND FINE ZERO CALIBRATION Use the following steps to make your final calibration adjustments: 1. Verify Zero on the analog Outputs for the “unloaded” condition and adjust the (Fine) Zero POT to correct for any minor offset voltage. 2. Apply the calibration force to the transducer(s) and adjust the Gain potentiometer to achieve the desired span. 3.

DIN RAIL AMPLIFIER, MWI-13262 ULTRA SERIES MAN-13262 ULTRA REV BA Appendix B. CABLE GLANDS Several manufacturers provide cable glands that can be used to ensure the integrity of the EMC requirements when installing this equipment in the enclosure. The objective of the cable gland is to provide a good mechanical entry into the enclosure to protect the cable and also provide an electrical bond the outer shield (screen) of the cable to the enclosure.
