Activation Method (Independent)
Independent Setpoints can be activated when either the gross weight, net weight or quantity (if
counting is enabled) is above or below a target value. When an independent setpoint is set to
Activate Above, the setpoint will activate when the selected mode (gross, net or quantity) is equal
to or above the target. When set to Activate Below, the selected mode must actually be below the
target.
Independent Status Annunciator Status Setpoint Status (Requires Setpoint Option Board)
Setpoint 1 Active SP 1 Illuminated Relay 1 Closed
Setpoint 2 Active SP 2 Illuminated Relay 2 Closed
Setpoint 3 Active SP 3 Illuminated Relay 3 Closed
Table 3-11: Independent Setpoint Reset (deactivation) choices
Parameter Setting Reset Choice Description
P51x5.0 Tare Setpoint deactivates with [TARE].
P51x5.1 Remote Key Do not use.
P51x5.2 Auto
Setpoint deactivates when weight returns to +/- 5 graduations of
zero and stabilizes.
P51x5.3 Non-Latched
Setpoint deactivates when weight value is in a range opposite of the
activation setting.
P51x5.4 Reset Value
Setpoint deactivates when weigh reaches a second value and
stabilizes.
The Pre-Acts, Learn Mode, and Pause Feature options are not applicable to Independent Setpoint
operation.
Changing Targets From The Weigh Mode (Independent)
When Independent Setpoints are configured in the setpoint setup, Targ 1, 2 and 3 automatically
become available modes for the [SELECT] key. An entry followed by [TARE] or
[SAMPLE/Enter] changes the currently viewed target. If the reset for a setpoint is set to 'value',
then pressing [TARE] or [SAMPLE/Enter] alone will allow access to the subset of the target. Rtrg
1, 2 and 3 are the respective subsets for Targ 1, 2 and 3. See Changing Targets from the Weigh
Mode (General) on page 38 for detailed instructions on changing target values from the Weigh
Mode.
Example (Independent)
Setup a continuous-cycle static weighing system that fills a weigh hopper from a storage bin. The
weigh hopper should stop the fill at a predetermined target, dump the product into a bag, and
then restart the fill. A warning light should come on to give an operator advance notice to change
the bag. The following setup might be used to achieve 1000 lb dumps:
