With the flowmeter housing installed, mount the MQ95540 to a rigid support structure. With the outer gasket in place, bolt the MQ95540 to the housing. Adjust the sensing head leveling hardware (provided) to establish level in both horizontal planes. Note: Ensure the sensing head mounting structure is capable of supporting the dynamic material impact forces as well as the weight of the sensing head. spirit level moving beam (machined surface) rigid support Sensing Plate 1. With the sensing head cover removed, remove the taper pin. Insert the sensing plate shaft fully into the sensing head socket. Note: Ensure the sensing plate shaft is installed with the flat side up. 4. Insert the taper pin (flat side down), from the left side. Tighten the right taper pin nut to lock the sensing plate shaft in place. Tighten the left taper pin nut. shaft socket flat side up taper pin (flat side down) Page 4 Milltronics MQ95540 ­ INSTRUCTION MANUAL 7ML19985CX01 Viscous Damper 1. Good housekeeping practices in the area of the flowmeter are recommended. Maintenance Description Regular Clean area around flowmeter Check sensing place surface* Check damping fluid Check sensing head inner gasket Check sensing plate wear Check test weight Rate display Test flowmeter linearity Frequency Monthly Semi-Annual Annual * Material buildup (if any) in the impact area of the sensing plate should be removed. Spare Parts Milltronics recommends a spare inner and outer gasket, sensing plate, and spare damping fluid be kept on hand. Contact Milltronics or your distributor for spare parts ordering information. Unit Repair and Excluded Liability All changes and repairs must be done by qualified personnel and applicable safety regulations must be followed. Please note the following: · · · · The user is responsible for all changes and repairs made to the device. All new components must be provided by Siemens Milltronics Process Instruments Inc. Restrict repair to faulty components only. Do not re-use faulty components. 7ML19985CX01 Milltronics MQ95540 ­ INSTRUCTION MANUAL Page 11 Inner Gasket Placement Should it ever be necessary to replace the sensing head inner gasket, refer to the Installation and Figures sections of this instruction manual prior to performing the following procedure. Remove the MQ95540 fibreglass cover, (10 bolts). Bolt down the viscous damper cover to the shipping position, (2 bolts). Remove the sensing plate from the sensing head. Remove the inner retaining ring, (6 bolts). Remove the upper and lower hinge block bolts, (4 per block). [. . . ] Refer to the integrator manual, Calibration. Milltronics MQ95540 ­ INSTRUCTION MANUAL Page 13 7ML19985CX01 Troubleshooting Every Millltronics MQ95540 sensing head is subjected to extensive quality assurance procedures to ensure the highest degree of quality, reliability, and performance is achieved. The following listing indicates the probable cause, and proper course of action to be taken should the specified fault symptom occur. Symptom Cause Action Refer to Installation\Integrator LVDT Interconnection Refer to Installation/ Viscous Damper Program and Calibrate the integrator Refer to Range Springs Wrong or bad integrator connection Integrator Rate display Viscous damper lid in shipdoesn't change when sensing ping position plate is moved Integrator not prepared for operation Span adjustment does not have enough range Range spring not suited to application Sensing head not level Refer to Installation and Calibration/Sensing Head Level Test Moving beam is mechanically Ensure moving beam does not limited hit travel stops between -20 % Measurement results are not and 150 % flowrates repeatable Leaf springs are damaged Replace leaf springs, recalibrate flowmeter, and integrator Material flow patterns vary Consult Siemens Milltronics or your distributor Accuracy varies with material flowrate Non-linear operation Refer to Linearity Page 14 Milltronics MQ95540 ­ INSTRUCTION MANUAL 7ML19985CX01 Linearity To test linearity, at least 3 test weights are used. Each weight represents a different test rate. [. . . ]
