IT
INTEGRATED TECHNICIAN™ (IT) is a system diagnostics utility which, in conjunction with an HI 6010IT or HI 6020IT
junction box, continuously monitors the excitation circuit (with up to 4 load sensors for the 6010 and up to 8 load
sensors for the 6020) for possible malfunctions. IT reads individual load sensor voltages and weights and isolates
individual system components for quick and easy troubleshooting.
If you do not have the HI 6020IT or HI 6010IT Junction Box connected to the module, the mV/V reading is
displayed as the total for all the load sensors on the system.
Return to Zero Test – Optional
This test requires the HI 6020IT or HI 6010IT Series Junction Box to monitor individual load sensors. It compares
the original voltage reading (saved at calibration) against the current voltage reading of an empty vessel. The
test checks for damaged load sensors due to electrical zero shift or abnormal mechanical forces that cause
binding on one or all of the load sensors in the system.
NOTE:
The HI 1734-WS
IS
compatible with the Hardy HI 6020IT, HI 6020JB HI 6010 IT or HI 6010JB. You
must use the HI 6020IT or the HI 6010IT to run this particular test. The HI 1734-WS is not
compatible with the Hardy HI 215IT Junction Box. It is compatible with the HI 215JB without the
IT functions.
Weighing System Test – Optional
For full utilization, this test requires the HI 6020IT or the HI 6010IT Series Junction Box. The Weighing System
test is used to diagnose drifting or unstable weight reading problems. The Weighing System Test does the
following:
1.
Disconnects the load sensors and engages an internal (in the junction box) reference signal to see if the
cable between the instrument and the Junction Box is causing the problem.
2.
Reads the weight of each load sensor to see if the load sensor might be causing the problem.
The ability to read the weight seen by each individual load sensor allows use of this test to make cornering,
leveling and load sharing adjustments to the weighing system.
Auto Zero Tracking
Auto Zero Tracking automatically adjusts for zero weight. This capability allows the module to ignore material
build-up in the weighing system within a pre-set auto zero tolerance. For auto zero to work, the current gross
weight must be within the auto zero tolerance. The current gross, plus any previously zeroed weight must be
within the Zero Tolerance level value and the scale must not be in motion. This is not used on all applications
and should be reviewed before use.
NOTE: The amount of weight zeroed off is cumulative. The Auto Zero command will not run if the current gross
weight plus any previously zeroed amount exceeds the zero tolerance value.
