Installation Instructions Stationary Weighpad_ELWC - WIM

! Insert the securing rails and attach with locking nuts and spring washers
provided. Run the nuts down snug, using a staggered pattern. This will ensure
the weighpad is centered in the frame. Then tighten the nuts with a torque
wrench to 85 Ft-Lb torque, again in a staggered pattern.

! Verify that weighpad corresponds to roadway level over entire width by means
of a straight edge. If weighpad is lower by more than 1/32", adjust shims
accordingly and check again. Allowable tolerance is ±1/32".
! Install other weighpads in the same manner. Before inserting the last weighpad,
pull connecting cable through the conduit. Make sure the cable is not subject
to torsion, does not form any loops, and is not bent. Leave slack underneath the
frame of about 2', to allow for maintenance removal of the weighpad.
! Carefully cut off protruding red silicone rubber from securing rails. Do not cut
into the weighpad rubber, or the connecting cable.
! Seal with silicone the joints between weighpad, frame, and securing rails on the
short ends. Also, fill each recessed nut hole with silicone. This is to keep
debris out, not to prevent entry of water.
! Open the roadway to traffic after the epoxy, silicone, and loop sealant have
cured sufficiently. See the appropriate data sheets for cure time charts. This
is usually one to five hours, depending on temperature.
