Page 6: Mounting Procedure
Mounting Procedure The TuffSeal junction boxes come in two sizes: • 4-Channel small enclosure (JB4ES and JB4SS) • 4-Channel mid-range FRP enclosure (JB4EP and JB4SP) The junction boxes should be mounted in a location that is convenient for servicing and away from standing water. Mount the enclosure in a location that allows for the cable supplied, do not cut the cable. -

Mid-Range Junction Boxes (JB4EP and JB4SP) Depending on the mounting surface, the JB4EP and JB4SP enclosure can be attached using four pan-head screws, bolts or other suitable masonry fasteners. 9.25" (235mm) 7.25" (184mm) 4.00" (101.6mm) 4x 0.31 holes 8.75" (222mm) 5.25"... -
Page 8: Junction Box Wiring
Junction Box Wiring All TuffSeal junction box models have been designed to connect and trim up to four load cells per board. It is possible to use this box with other combinations. Use the expansion port on the main board, to connect multiple junction boxes in series to accommodate applications that have more than four load cells. -
Page 9: Connect Indicator
Connect Indicator The indicator terminal strip is used to connect the main cable to the indicator. 1. Determine the indicator’s load cell input connections from the indicator manual. 2. Run a cable from the indicator terminal into the junction box through the cord grip. Indicator Indicator Cable... -
Page 10: Trimming Procedure
Trimming Procedure Trimming is a process of equalizing the output from multiple individual load cells. If needed, load cell output can be individually trimmed with potentiometers. If more than 5% of normal output needs to be trimmed to equalize output, check for other possible problems. - Page 11 7. Allow the scale to return to zero each time to check for friction or other mechanical problems. 8. Select the load cell with the lowest value as the reference load cell. This load cell will not be trimmed. 9. Place the same test load over one of the other load cells. 10.Use the corresponding potentiometer to trim the load cell equal to the reference load cell.

Page 12: Signal Board Trimming Procedure (Jb4Ss And Jb4Sp)
Signal Board Trimming Procedure (JB4SS and JB4SP) Use the following steps to properly trim the JB4SS and JB4SP junction boxes. 1. Determine the number of load cells needed. 2. Ensure jumpers are in place to enable trimming the load cells. Remove jumpers for unused cells. - Page 13 11.Repeat Steps 9 and 10 until all remaining load cells have been trimmed. 12.Once trimming is complete, check all loads cells again for repeatability. If necessary, repeat Steps 4 through 11. 13.Pull excess cable out of the enclosure. 14.Tighten the cord grip assemblies with a wrench. To be watertight, each cord grip must be tightened so the rubber sleeve begins to protrude from the hub.
