1) of Tare subtraction bit (0th bit of n CH) triggers tare
subtraction, zero-clearing Net weight.

Feeding starts with all valves full open. When the weight reaches (Final-
SP1), SP1 signal turns ON (9th bit of n+3 CH) and the Comparison inhibit
time starts (if enabled). Travel of the raw material tank valve changes from
“large” to “medium”.

When the weight reaches (Final – SP2), SP2 signal turns ON (10th bit of n+3
CH) and the Comparison inhibit time starts (if enabled). Travel of the raw
material tank valve changes from “medium” to “small”.

When the weight reaches (Final – FF CPS.), SP3 signal turns ON (11th bit of
n+3 CH) and the Compare time starts (if enabled). Feed valve is totally
closed.

When the Compare time expires, Over/Under judgment is made. If the
weight exceeds the range of Over/Under set values, Over or Under signal is
raised.

Open the metering tank valve to discharge the material into the container.
Completion of discharge can be confirmed by checking Near zero signal (8th
bit of n+3 CH). Repeat steps (1) to (5) for the next container.
Use CJ1 or appropriate relay sequencers to open/close the Feed/
Discharge valves, and these sequencers are controlled by F159.
