7.CONTROL SIGNAL (External I/O Connector)
98
7-4-4. Total weight clear (edge input)
The value of TOTAL is zero-cleared by the falling edge (OFF->ON).
* This input is ignored while RUNNING is on.
7-4-5. Digital Zero (edge input)
GROSS WEIGHT is cleared to zero by ON edge (OFF->ON).
Note, however, GROSS WEIGHT must be within the range specified by DZ REGULATION
VALUE for this function to operate properly. If the value is out of range, it will not be cleared
and ZALM will come out (in reversed-red) to report irregularity.
DIGITAL ZERO, used for function settings, also behaves in the same fashion.
7-4-6. Zero point auto adjustment (edge input)
Zero-point automatic adjustment is triggered by a falling edge (OFF->ON).
The zero point measurement is performed in [TEST MODE], and [ZERO ERROR
SET] value is automatically updated. ZERO ERROR MEASURING signal (45-pin)
turned on while this measurement is in progress. Successful completion of the
measurement will output ZERO ERROR MEASUREMENT OK (46 pin).
This procedure is disabled if the system receives a falling edge while load ration
exceeds the value dictated by [Z_ERR UPPER LIMIT]. Note also that this process is
aborted if the following conditions occur, outputting a ZERO ERROR
MEASUREMENT NG (47 pin).
・
Load ratio exceeds [Z_ERR UPPER LIMIT] during the process
・
is pressed
・
The signal changes from ON to OFF (rising edge) during the process
If this process ended abnormally, [ZERO ERROR SET] will not be updated (the value
prior to the adjustment process will be retained).
* This input is ignored while RUNNING is on, and when the system is in one of other
modes.
