remote module. The HI 1746-WS module can be used
for a wide variety of process weighing applications
such as batching, blending, filling/dispensing, check
weighing, force measurement, level by weight and
weight rate monitoring. The module can control two
(2) relays via two (2) TTL level outputs and transmits
data via the back plane to the SLC. The 20 bit analog
to digital converter in the weigh module controller
updates twenty (20) times per second and is capable
of 985,000 counts of display resolution. This gives the
instrument the ability to tolerate large “dead” loads,
over sizing of load cells/sensors and still have suffi-
cient resolution to provide accurate weight measure-
ment and control. The HI 1746-WS module is set up
by using the SLC 500 AI Series, RS Logix500

WS100 Configuration Software. The software config-
uration applications must be installed in a PC with
either Ethernet, DH+, DH-485, or RS-232-C that can
initiate communications with the SLC 5/02, 5/03, 5/
04 or 5/05. To calibrate the module you can simply
push “The Button” to effect a C2 calibration. C2,
Hard (Traditional calibration with weights), and Soft
calibration can be implemented from the SLC 500 AI
Series DOS software, RS Logix500

Technician) enabled which means the module has a
built in IT excitation monitor to detect some load cell
problems and with the addition of the optional HI
215IT Junction Box and the HI WS100 software, the
operator can use the other IT functions for fault isola-
tion troubleshooting of the weighing system.

Typically, mechanical noise (from other machinery in
a plant environment) is present in forces larger than
the weight forces trying to be detected by the module.
The HI 1746-WS is fitted with WAVERSAVER
®
technology which eliminates the effects of vibratory
forces present in all industrial weight control and
