28 Indicator applications 6. Place a weight on the scale If the weight is below the lower accept weight, the left bargraph segments will light. Any weight between the lower and upper acceptable weights will cause the middle bargraph segment to light to show the weight is within the target range. If the weight is above the upper acceptable weight, the right bargraph segments will light. 7. Remove the item from the scale and repeat step 6 to check other items. 8. To set new upper and lower limits, repeat steps 1 through Setpoint operation in the checkweighing application Inside the Gross Zero Band = All outputs and annunciators are off. Under Target or Below Low Accept Weight = SP1 annunciator and Output 1 are on. Inside Target = SP2 annunciator and Output 2 are on. Over Target or Above Upper Accept Weight = SP3 annunciator and Output 3 are on. Outputs have to be enabled (see Service manual). Contact AWTX technical support for information about setpoint use with battery operated scales. Outputs can be set as latched or unlatched in a password protected menu. If outputs are unlatched If outputs are latched The annunciators and outputs follow the status of the bargraph except in gross zero band. The annunciators and outputs status is determined by where the first stable weight occurs after an item is placed on the scale. The latched annunciator and output is reset OFF only when weight returns inside the gross zero band. 28 ZM305 Standard Indicator User Instructions

29 3.5 Batching application 3.5 Batching application This section applies if your indicator has the Batching application active SELECT key default function In the Batching application you can view the gross, net and tare display s by repeatedly pressing SELECT Special key functions The following keys have an extra function in this application: START STOP F1 Press START to start or resume a batch operation. Press STOP to pause a batch operation. Press STOP a second time in succession to abort the batch operation. F1 acts as a START and a STOP key on successive presses. The Batch application has added selections for Preact s (1-3) in the Setpoint menu, shown below: Press SETUP Setpnt out1 out2 out3 Preact1 Preact2 Preact3 setpoint setpoint setpoint preact preact preact Setpoint or Preact s can be either positive or negative, up to or equal to scale capacity. See Entering a negative number on page 14 on how to enter negative s. PREACT definition - A preact is the amount of material in free fall. For example: You would like 1000 lbs of material added to a scale but when the supply valve closes you always end up with a final weight that is 120 lbs over the desired amount. To correct this, set a preact of 120 lbs. This causes the setpoint controlling the material to stop sooner and allows the material in free fall to be accounted for in the final weight. In Discharge or Negative fill applications using manual preact, the preact weight will typically be entered as a negative. ZM305 Standard Indicator User Instructions 29

30 Indicator applications Batching operation Batching allows the indicator to control up to three motors, timers, augers, gates, etc. using the three outputs for the purpose of making batches based on weight. There are four types of batching operation: l l l l 2-speed single ingredient Ingredient filling (up to three ingredients) Independent setpoints filling Fill/discharge operation Other parameters, that are set in a password protected menu, affect the batching operation. The bargraph will sequentially light up to show from 0 to 100% of the batch weight in all types of batching except the independent setpoints Speed filling 2-Speed is for a single ingredient with a dual speed filling control (Fast/Slow), typically a valve or hopper gate that can be full open, partially open or closed. When the fill starts both SP1 and SP2 are turned on (outputs activated) which should set the dual speed control to full open (Fast speed). When the Out 1 is reached SP1 and Output 1 are turned off and this should set the dual speed control to partial open condition (Slow speed). When Out 2 is reached SP2 and Output 2 are turned off to close the control device and complete the fill. SP3 and Output 3 can be used as a Batch Cycle Active indicator. 1.

Fill/Discharge Fill/Discharge mode is typically used for applications that use negative filling to dispense a smaller amount of product from a large vessel, tank or hopper type scale. The vessel (tank or hopper) is filled to a set gross weight and then multiple operations of filling via negative amount of weight into bags or containers can be completed before the vessel (tank or hopper) requires a recharge or refill. Fill Discharge Out 1 is assigned as the gross fill amount for the vessel (tank or hopper) and START or F1 key starts the fill. The fill is based only on gross weight. If you have Out 1 set to 2000 and the scale already has 500 lb remaining, the Output 1 will cutoff (and annunciator SP1 turns off) when the additional 1500 is added for a total gross of 2000 lb. Out 2 is assigned as the discharge fill amount (negative weight) with the TARE key used to initiate the discharge cycle. The scale will tare prior to activating Output 2 (SP2 annunciator will light). An operator can perform multiple discharge operations. When the vessel gross weight is low, perform a refill. 1. Press SETUP or press and hold SELECT to access the setpoint editor. 2. Set Out1 to the gross fill weight in the vessel or container. Set Out 2 to the weight of the product to be discharged into smaller bags or containers. 3. To start or restart the large vessel fill process, press START or F1. 4. To stop the large vessel filling process, press STOP or F1. 5. Press TARE to start the bag filling process. 6. To stop bag filling process, press STOP or TARE. ZM305 Standard Indicator User Instructions 31

Numeric entries are non-functional from a remote display unit, or secondary indicator, such as numeric tare entry, numeric ID entry, etc. If the Remote indicator is connected to a GSE 35xIS Primary indicator, then additional features and options may be available for use from the remote such as setpoints, remote inputs, Com port communication forwarding to local devices and analog output option. Contact your local Avery Weigh-Tronix representative for information on setting up the ZM indicator as a Remote or Primary indicator. ZM305 Standard Indicator User Instructions 33

34 Indicator applications 3.8 In-Motion application This section applies if you have the In-Motion application active. In-motion weighing involves items moving across a conveyor scale. When the item is completely past the beam of the entrance photo-eye the weight capture starts at the ADC rate of 80 samples per second. While weight is being captured the indicator will show. When the item breaks the beam of the exit photo-eye the weight capture stops and the average of all the weight readings is displayed for a configured length of time or until the next item breaks the beam of the entrance photo-eye. GROSS or NET annunciator will light depending on if a Tare is active. GROSS NET lb These three annunciators light during in-motion weighing. A print of the averaged weight will occur when the exit photo eye is tripped. If the averaged weight timer expires before the next item arrives the display will show middle dashes SELECT key operation Press the SELECT key to toggle between gross weight and the in-motion weight. The in-motion weight will have either the Net or Gross annunciator turned on depending on if Tare is active. 34 ZM305 Standard Indicator User Instructions
