When Discharge is configured in the setpoint setup, Targ 1 automatically becomes an available mode for the ! key.
An entry followed by 1 or ( changes Targ 1. Pressing 1 or ( 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 65 for instructions on changing target values from the
Weigh Mode.
Target and pre-act values are entered as positive values.
If the total amount of product in the weigh vessel is less than the entered target, the indicator will prompt Tare ~
=Cont. Pressing 1 will dispense whatever is left in the vessel. Pressing any other key will abort the discharge cycle
to allow for refilling the vessel.

With a system set up to dispense ball bearings from a 50,000 lb weigh-bin and the fast-feed requiring an early cutoff to
slow-feed, the following settings might be used to achieve accurate dispensing of 1000 bearings:
Parameter Setting Actual Cutoff Value Comments
Targ 1 = 1000
0 – 1000 =
(-1000)
Desired quantity (decreasing value from a net zero: enter as a positive
value).
Based = Qty Targets are compared to quantity (P170 Enabled).
PA 1 = 200
1000 – 200 = 800
0 – 800 = (-800)
Switch to slow feed at –800 bearings (decreasing value from a net
zero: enter as a positive value).
Start = # Start discharge with # .
PA 2 = 15
1000 – 15 = 985
0 – 985 = (-985)
Final gate begins closing at 985 bearings. Delayed closure brings final
quantity to 1000 (decreasing value from a net zero: enter as a positive
value).
Learn 2 = Enabled Analyze five previous operations and auto-adjust Pre-Act 2.
PrAc 1 = Enabled Pre-act 1 available as subset of Targ 1 in Weigh Mode.
PrAc 2 = Disabled
Pre-act 2 NOT available as subset of Targ 1 in Weigh Mode (auto-
adjust only).
Pause – Remote Remote key closure invokes Pause.
Both
The ‘Both’ program combines a fill operation with a discharge operation. This automates a single-speed vessel filling
operation with a single-speed multiple dispensing function. Setpoint 1 is used for filling the vessel and Setpoint 2 is
used for product discharge. The ‘both’ program uses values for two targets and two pre-acts. Both targets must be
based alike (net or quantity, quantity if count is selected).
