See Pre-acts (General) on page 37 for details on the operational functions of pre-acts.
Learn Feature (Fill)
Pre-act 2 has a learn feature available which allows the Model 370/375 to adjust the final cutoff
based on changing environmental conditions. See Learn Feature (General) on page 37
for 'learn'
feature details.
Pause Feature (Fill)
The standard pause feature (keypress, remote key closure or both) is available for the fill
operation. See Pause Feature (General) on page 37
for 'pause' function details.
Changing Targets From The Weigh Mode (Fill)
When fill is configured in the setpoint setup, Targ1 automatically becomes an available mode for
the [SELECT] key. An entry followed by [TARE] or [SAMPLE/Enter] changes Targ 1. Pressing
[TARE] or [SAMPLE/Enter] alone allows access to the subsets. PA 1 and PA 2 are the subsets
for Targ 1. The pre-acts can be deleted as subsets by choosing 'disabled' at P5114 and P5115.
See Changing Targets from the Weigh Mode (General) on page 38 for instructions on changing
target values from the Weigh Mode.
Example (Fill)
With a system set up to fill 55-gallon drums with motor oil, the following settings might be used to
achieve an accurate final fill weight of 400 lbs.:
Parameter Setting Actual Cutoff Value Comments
Targ 1 = 400 Desired final weight.
Pre-act 1 = 28 400 – 28 = 372.0 Switch to dribble feed at 372.
Pre-act 2 = .5 400 – 0.5 = 399.5 Final fill valve closes at 399.5.

The standard batch program is used for batching up to three separate items. Ingredients 1
