Zero Setting
The zero setting program is designed to acquire the belt
weigher’s zero point error over one or multiple integer
belt circuits.
In normal mode, value is used to correct current
measuring result.
If no automatic mode is selected, use program in regular
intervals.
During zero setting, totalizing counters stop counting.
Prerequisite:1. Conveyor belt totally unloaded.
If necessary, abort program.
User “Start Prefeeder” function, if
available.
2. Belt running,
indicated automatically.
3. No batch active; batching mode can
remain active.
4. This function has to be activated with
the parameter A08.
Call:
G
TU
f
Call Zero Setting function and start.
If belt is not running, program aborts
and requests START.
Program running:
Upper display: Residual run time in % of total run
time.
Lower display: Zero point error in %, related to
nominal belt load.
N Abort program at any time.
Program complete:
Upper display: Deviation of zero point from
previous zero setting operation in %
of nominal belt load.
Dev=+:error increased
Dev = - : error decreased.
Lower display: Deviation of zero point from basic
tare in % of nominal belt load.
Taring program corrects basic tare
during calibration.
Acquire result, or view for information and reject.
f Acquire result.
Scale zero point is corrected.
N Abort program.
Result is rejected.
Restart prefeeder.
Event messages:
1- C7 Zero setting time elapsed.
Deselect message, if not desired.
2- Value Excessive
Zeroing range exceeded; clean
scale and retare, if necessary.
3. Note:
The function setting to zero can also be
started via the digital input P05. The
program is started by a positive flank of the
contact. The result is automatically accepted
if it is within the admissible zero setting limit
(5% of the nominal belt load). An
ackowledgement of the result is not
necessary. The calibration program can only
be aborted in its active phase.
