FLIGHT: Set the amount of material that is in-flight. This is used to turn the output off before the
target it reached so it does not overshoot.
LOCK: Set if the target and flight values will be locked from editing in the OPER menu.
SOURCE: Select the weight source for the setpoint to use. Options are:
– GROSS uses gross weight only
– NET uses net weight only
16.6 Status Based Setpoint Types
The following setpoint types are all based on the status of the instrument.
NONE: Setpoint is always inactive.
ON: Setpoint is always active. This type of setpoint is useful to show that the instrument is running.
Centre of Zero (COZ): Setpoint is active when the gross weight is within COZ bounds.
ZERO: Setpoint is active when the gross weight is within the Zero Band setting.
NET: Setpoint is active when the NET annunciator is lit.
MOTION: Setpoint is active when the MOTION annunciator is lit.
ERROR: Setpoint is active when the instrument detects any error condition signified by the display of
Exxxxx on the display.
BUZZER: Setpoint is active when the buzzer beeps.
16.7 Example 1 (filling a bag)
Type = Over, Logic = High, Source = Gross, Target = 2000kg, Inflight = 50 kg, Hysteresis = 5 kg. Initial
weight = 0 kg.
Trip point = target - inflight = 2000 - 50 = 1950 kg.
The output will switch ON at a weight over 1950 kg and switch OFF again at a weight under 1945 kg.
If the type is changed to weigh in the output will be ON at 0 kg, switch OFF at a weight over 1950 kg and
switch ON again at a weight under 1945 kg.
16.8 Example 2 (loss in weight system)
Type = Under, Logic = High, Source = Net, Target = -100kg, Inflight = 5 kg, Hysteresis = 1 kg. Initial
weight = 0 kg.
Trip point = target + inflight = -100 + 5 = -95 kg.
The output will switch ON at a weight under -95 kg and switch OFF again at a weight over -94 kg.
