Enclosures
The 920i is available in four enclosures: universal
(tilt-stand), deep enclosure, panel mount, and wall
mount. Stainless steel enclosures are rated for NEMA
4X/IP66. This manual provides assembly drawings and
replacement parts lists for the universal model;
supplemental documentation provides information
specific to the panel mount and wall mount models
(Section 1.5 on page 5).
1.1 Operating Modes
The 920i has two modes of operation:
Normal mode
Normal mode is the weighing mode of the
indicator. The indicator displays gross, net, or tare
weights as required, using the secondary display to
indicate scale status and the type of weight value
displayed. Once configuration is complete and a
legal seal is affixed to the large fillister-head screw
on the indicator enclosure, this is the only mode in
which the
920i can operate.
Setup mode
Most of the procedures described in this manual
require the indicator to be in setup mode, including
configuration and calibration.
To enter setup mode, remove the large fillister head
screw from the enclosure. Insert a screwdriver or a
similar tool into the access hole and press the setup
switch once. The indicator display changes to show
scale configuration menus.
