6.6.3 Clamshell Installation
Protective stainless steel clamshells are available as an option for all RL2100 bench scales. Clamshells are
pre-drilled for load cell screws, overload screw, and cables. Existing load cell shims are reinstalled inside
the clamshells.
To install the clamshell, do the following:
1. Remove platter, spider plate, and load cell using the procedure described in Section 2.4.1 on page 7.
2. Install lower clamshell in base. Route load cell cable through lower clamshell and grommet., then reinstall
lower shim and load cell so that no part of the load cell touches the clamshell enclosure. Replace lower
load cell screws and lock washers. Torque to 80 in-lb (9.0 N-m).
3. Install upper clamshell, ensuring clearance on all sides to prevent binding against the lower clamshell.
Reinstall upper shim, spider plate, lock washers, and upper load cell screws. Torque screws to 80 in-lb (9.0
N-m).
4. Replace scale platter. Ensure that scale is level.
5. Readjust lift-up protection screws and overload protection set screw on bottom of scale base as described
under Section 2.4.2 on page 8.
6. Connect load cell cable to indicator. Power-up indicator and recalibrate scale.
