16.10 Checkweighing function (thr)
This function allows comparing weighing result with two programmed reference values: lower and upper
threshold. Comparison result is signalled with indicators (MIN, OK, MAX) and sound signal generated (in
Impulse
mode)when threshold values are exceeded.
-
Standard scale is set for cooperation with optical indicator.
On outputs P1-P3 (
Relays
socket) short-circuit states appear as result of comparison scale indication with
threshold values.
On the chart below output states are shown during increasing load on the scale for both working modes:
Indication mode: Batching mode:

In
Batching
mode on P1 (thr I) and P2 (thr II) outputs short-circuit impulses appears for time of 0,5s. On P3
(zero) output short-circuit state appears when indication does not exceed threshold value signalling zero
load.
