INTRODUCTION Product overview The MAGPOWR TLC-B Load Cells are extremely accurate devices used to measure tension in any unwind, rewind, or intermediate web processing application. The load cells are to be mounted in a machine supporting an idler roll in a part of the machine where measurement of web tension is desired.
SAFETY INSTRUCTIONS Instructions for To ensure safe and problem free installation of the load cell device, the load cell must be properly transported and stored, professionally installed and placed in operation. Proper operation and maintenance will ensure a long service life of the device.
SAFETY INSTRUCTIONS Symbols used The following safety identification symbols are used in these operating instructions. WARNING/CAUTION – General danger or important note Reference to general hazards that may result in bodily injuries or damage to device or material. WARNING/CAUTION – Danger due to crushing Reference to danger of injury caused by crushing.
SAFETY INSTRUCTIONS Basic safety information Proper use The load cell devices are intended to be used on machines or systems to monitor the tension in a web. Indoor operation. Improper use Operation outside the technical specifications Operation in an Ex-area or intrinsically safe area, unless used with a MAGPOWR IS2 barrier.
MOUNTING DIMENSIONS Shaft and roller diameters When mounting inside the machine frame, clearance is required for the installation fasteners. See dimensions illustrated below. If 'Y' will be less than 50 mm [2.0 inches], then the roller diameter 'X' should be less than the diameter of the intended mounting bolt circle: 3-bolt pattern: 150 mm [3.5 inches] maximum 4-bolt pattern: 135 mm [3.0 inches] maximum...
INSTALLATION General installation CAUTION – Possible damage to load cell. Do not hammer on the load cell. CAUTION – Possible damage to load cell. Do not disassemble the load cell – there are no serviceable parts inside the unit. WARNING – Danger of injury from crushing. Maintenance and repair tasks on the load cell device must be performed only when the machine has been stopped and has been secured from being turned on again.
INSTALLATION Resultant force polarity The label on the load cell indicates the output polarity based on the resultant force direction in relation to the connector. Default wiring Cable wiring diagram + Power Pin 1 (A) + Signal Pin 2 (B) White - Signal Pin 3 (C)
INSTALLATION Flange mounting The TLC-B Load Cell can be mounted using one of two bolt patterns: 3-hole on a 150 mm bolt circle 4-hole on a 135 mm bolt circle Before installation, each machine frame must be prepared with a 100 mm hole for the load cell hub and M8x1 (or 5/16") threaded holes for the fasteners.
INSTALLATION Pillow block mounting When using the optional pillow block bracket, the load cell can be rotated in 30° increments to align the resultant force with the connector. One bracket per load cell required; - MAGPOWR Part No. TLCB-PBK Fasteners Mount load cell to pillow block bracket (kit included) - M8 bolts - Minimum fastener length is 75 mm [3.0 inches]...

INSTALLATION Bearing and shaft installation Inside machine frame mounting – continued Installing the shaft assembly 1. Align the shaft assembly between the machine frames and slide the floating load cell inboard until the hubs fit between the frames. There will be some axial clearance to allow for fit.
4-10 INSTALLATION Bearing and shaft installation – continued Outside machine frame Use the illustration on page 4-6 for reference. Note the overload pins that are loose inside the covers. Ensure that they are in place before reinstalling the covers. NOTE: A fixed load cell uses two large retaining rings to secure the bearing; a floating load cell uses none.
