    1. Introduction General In the program version 1.5.0.0 the ‘G4 Modular Weighing Instrument’ includes a program option for ‘Batching’. The option can be activated by a code specific for each individual instrument. The code can be ordered from Nobel Weighing Systems and should be entered in menu ‘Program Options’...

  • Page 7: Batching Principles

    2. Batching principles General Batching with the G4 Instrument means performing up to 12 activities in numerical order as one sequence for each scale. Batching can be used with each used scale in the instrument. Each Scale Batching sequence operates independent of the other.

  • Page 8: Batch Start Check

    Technical Manual Supplement Batch start check When batching is started (start button or communication start command) an I/O usage check is done to verify that all the rules described above are followed. This check is only done for the scale to start. If there are any violations to the I/O usage rules there will be an error and the batching sequence will not start.

  • Page 9: Activity Description

    G4 Multi Channel Weighing Instrument 3. Activity description General In the description of activities below Scale 1 Activity 1 parameters are used as an example. The parameter names includes the scale number and the activity number. E.g. ‘1/1:AcivityType’ applies to Scale 1, Activity 1 while ‘3/4:ActivityType’ applies to Scale 3, Activity 4 etc.

  • Page 10: Weigh In

    Technical Manual Supplement Weigh In The Weigh In activity is used when the material is batched into the weighed vessel. Setpoint check When a Weigh In activity is started, the Setpoint value is checked to determine if the receiving container has sufficient capacity for the set quantity of material. The implication of this Setpoint check is that actual Gross weight + Setpoint value must be less than ‘S1:Capacity’...
  • Page 11 G4 Multi Channel Weighing Instrument  ‘1/1:Batching Mode’ is ‘Fine+Coarse’ and ‘1/1:Fine on during Coarse’ is ‘No’: The coarse output is activated. The instrument shows increasing weight. When the weight reaches ‘Coarse Level’ the coarse output is deactivated and the fine output is activated (Coarse Level = Setpoint –...
  • Page 12 Technical Manual Supplement Stability check after batching After the complete batching of a Weigh In (or Weigh Out) activity and Wait time, a stability check is performed if ‘1:Motion Check’ is ‘On’ (stability check is never performed for a Pulse Batching activity). Unstable weight initiates an alarm.
  • Page 13 G4 Multi Channel Weighing Instrument 100.00 % means that tolerance check is not performed (all weights are approved). 5.00 % means that the batched weight is permitted to deviate from the Setpoint value by 5 % thereof. If the weight is below the ‘1/1:Minus Tolerance’ limit, and a ‘1/1:Pulsing Time’ other than zero is selected, the fine output will be activated again for the time defined by the parameter ‘1/1:Pulsing Time’.

  • Page 14: Weigh Out

    Technical Manual Supplement Automatic inflight compensation Automatic inflight compensation is operative when the ‘1/1:Inflight Factor’ has a value higher than zero. It is used to adjust the ‘1/1:Inflight Value’ after each activity to bring the batched weight value as close to the Setpoint as possible. Automatic inflight compensation for any activity is performed by: New Inflight value = preceding Inflight value + (batched weight - Setpoint value) x ‘1/1:Inflight Factor’.

The batching sequence continues immediately.

  • Page 19: Manual

    G4 Multi Channel Weighing Instrument Manual A Manual activity halts the batching to allow special operations that must be carried out manually. (For example, to add small quantities of material manually.) Before batching is halted autotaring is performed, which means that the net weight zero is displayed when the manual operation starts.
