15.24. Function of comparing with preset threshold values (trESh)
This function compares weighing result with two reference values: lower and
upper threshold. The balance signalises comparison result with MIN, OK and
MAX indicators and sound signal generated when threshold values are exceeded.
If comparison result is:
- smaller than lower threshold – the balance displays MIN,
- between threshold values - the balance displays OK with the sound signal
when exceeding the threshold,
- greater than upper threshold - the balance displays MAX with the sound signal
when exceeding the threshold,
If the balance is equipped with
THRESHOLDS
control connection, the
comparison result may be used to control:
- optical signalling devices (
SIGNAL
mode),
- batching devices (
IMPULS
mode).
In standard configuration the scale is set up to cooperate with optical signalling
device.
On the outputs
P1
and
P2
the short-circuit states appear, which depend on
comparison results of balance indications with threshold values.
THRESHOLDS
outputs states chart (with increasing balance load) for both
modes:
SIGNAL
mode:
IMPULS
mode:
In
IMPULS
mode on outputs P1 (threshold I) and P2 (threshold II) short-circuit
impulses appear for about 0,5s. On output P3 (zero) short-circuit state appears
with the zero threshold indication.
