entered, it is rounded off to the nearest minimum division multiple.
- With the DFWLID/DFWLIDCC if you activate the tolerance check CHEK (F.ModE >> Funct >> Check, RIF.MAN.T,
TECH.MAN.REF.) you have the option to choose the color for each threshold of Check(under, ok and over).
PROCEDURE
After having entered the activation threshold, the target and the tolerance values, put the weight on the scale: if the target is
greater than 0, the display shows, at regular intervals, if the weight is within the entered tolerances:
Scale Display View Enable Relay Display Color (DFWLID)
Weight ≤ thrESh White
Weight < Target – t.Min _undEr reL.b.1 Yellow
Target – t.Min ≤ Weight _oK –X reL.b.2 Green
Weight = Target -oK- reL.b.2 Green
Weight ≤ Target + t.MAX oK X reL.b.2 Green
Weight > Target + t.MAX oVEr reL.b.3 Red
Weight ≥ thrESh reL.b.4
NOTE: X is the difference (1 digit) between the weight on the scale and the target.
ACOUSTIC SIGNAL
It is possible to enable an acoustic signal (beep) for the control of tolerance in two different mode:
- b.SeNS: that is emitted when the weight is greater than the enabling threshold; the frequency with which the acoustic
signal is emitted increases when the weight approaches the target and vice versa. When the weight reaches
the target, the indicator emits a different acoustic signal.
- b.out: that is emitted when the weight is less than Target-t.Min or greater than Target+t.MAX.
To enable this function, press the keys “F” and “6” in sequence (in the 17-key indicators) or the key “MODE”(in the 5-key
indicator): the display shows “b.SeNS”/”b.out” and then “StorE”; to disable the function press again the keys “F” and “6” or
”MODE” in sequence: the display shows “MutE” and then “StorE”.
TECHNICAL NOTES
- The 0 value is valid for the tolerances and for the activation threshold as well.
- By setting the target at 0 the weight check is disabled.
- If the printer has been configured and a target greater than 0 has been set, the target, tolerances, and check result will
be printed.
- The check of the weight is active also during the modification of the target and the tolerances, according to the last
confirmed values. The new entered values start working after having been confirmed.
- The 4 relays of the 2 expansion boards (optional) are automatically enabled depending on the mode selection , and
may be used to manage external signals which show the operator whether the weight on the scale is INSUFFICIENT,
CORRECT, ABUNDANT in comparison to the TARGET WEIGHT. Furthermore it is not possible to set the functioning
mode of the relays, but just the status (NO / NC) and the type of check (direct or upon stability).
- It is possible to set the target, the tolerances and the activation threshold through the serial line, see section “FORMAT
OF THE SERIAL COMMANDS”, TECH.MAN.REF..
11.9 SAMPLE WEIGHT PERCENTAGE (PErC)
In this operating mode, the instrument shows on the display the net weight expressed as a percentage, comparing it with a
reference weight which has been previously linked to a percentage.
When the functioning mode is selected, one is asked to set of:
- "WAit.t" : sampling interval.
Setting of the sampling time (in seconds, with a decimal); greater is the time set and more precise will the sampling be.
• Set the desired time.
• Confirm with ENTER/PRINT.
• Press many times the C key until the display shows the message “SAVE?”.
With the indicator fitted of a 17-key keyboard, by pressing the F and 7 keys, it’s possible to change the sampling time
