Detecto 825CBW Continuous Bulk Weigher User manual

Brand: Detecto

Model: 825CBW Continuous Bulk Weigher

Type: User manual

Detecto 825CBW Continuous Bulk Weigher allows you to automatically weigh and record large amounts of material in consecutive batches called drafts, which are summed to provide a total weight at the end of the weighing cycle. Once a weighing cycle is complete, you can print a record of the gross, tare, and net weights for each draft, as well as the total weights for the cycle.

The 825CBW can be set up to operate in either "ship" or "receive" mode, and you can choose to enter the total weight and draft size, or the draft size and number of drafts required. The system will automatically fill the weigh hopper to the required draft weight, record the weight, and then discharge the completed draft into a lower garner. This process is repeated until the required amount of material has been delivered or received or the process is stopped by the operator.

I. INTRODUCTION

The purpose of this manual is to provide information

describing the use, setup, operation and maintenance of the

Cardinal Model 825 CBW Continuous Bulk Weigher system. The

system is used to automatically weigh large amounts of

material by weighing them in individual drafts or

weighments then totaling the individual weights. The gross,

tare and net weights of each draft are recorded on the

printer.

Information covering the installation, calibration and use

of the Model 825 Weight Indicator is contained in the Model

825 PWI manual. A copy of this document is furnished with

the system and should be consulted for detailed information

concerning the use of the 825 PWI.

Information describing the use of the Cardinal P500 series

tape printer, including the loading of paper is contained

in the Printer Manual. This manual is also included with

the system and should be consulted for additional

information describing the printer.

II. GENERAL DESCRIPTION

The Cardinal Model 825 CBW is designed to control the flow

of material from a upper garner or hopper into a weigh-

hopper and from the weigh-hopper into a lower garner or

surge bin. This control is accomplished by activating the

discharge gates on the upper garner and the weigh-hopper.

Control of the flow of material into the upper garner and

out of the lower garner is accomplished by other controls

not provided with the Cardinal 825 CBW.

The system will accept either the total weight required

amount and draft size, or the draft size and number of

drafts required. The system will automatically deliver the

required amount of material by accurately filling the

weigh-hopper to the required draft weight, recording the

weight and then discharging the completed draft into the

lower garner. This process is repeated until the required

amount of material has been delivered or received or the

process is stopped by the operator.

III. SETUP

Several parameters must be set prior to operating the 825

CBW system. To get to the setup menu press the SETUP key on

the main screen. The main screen follows.

The CBW SETUP menu is shown after pressing the SETUP key.

TIMERS

This system uses a number of time delays to guard against

material outages and incorrect weight readings. Values for

these timers must be entered before operations begin. To

access these timer values, press the TIMERS key on the CBW

SETUP menu screen. The following screen will be displayed.

Page 2 of 28

The “Fill Alarm” timer is the maximum length of time given

for a draft to complete its filling before an alarm is

issued to indicate no material flow. If, for example,

material flows at a rate which allows the weigh-hopper to

fill to the required draft weight in 45 seconds you may

wish to set the timer to 55 seconds. After 55 seconds has

elapsed and the weigh-hopper has not reached the required

draft weight an alarm will sound signaling the operator

that the system is either out of material or there is a

problem with the material transporting system. To change

the “Fill Alarm” time press the UP or DOWN navigation key

to highlight the “Fill Alarm” value and then enter the

desired time value.

The “Dump Alarm” time is the length of time required for

the weigh-hopper to discharge a completed draft of material

and return to a weight less than the zero cutoff weight

before turning on the alarm. The alarm serves to warn the

operator that material is either lodged in the weigh-hopper

or that there is a discharge gate malfunction. For example,

if it takes 15 seconds to fully discharge a completed

draft, you may wish to set the timer to 25 seconds. To

change the dump alarm time press the UP or DOWN navigation

key to highlight the “Dump Alarm” value and then enter the

desired time value.

The “Fill Settle” time is the length of time that is

allowed to pass after fill is complete and motion has

ceased and the time the weight is recorded. To change the

fill settle time press the UP or DOWN navigation key to

highlight the “Fill Settle” value and then enter the

desired time value.

Page 3 of 28

The “Extend Dump” time is the length of time between

completion of a discharge of a draft from the weigh-hopper

and closure of the gate to the time when the empty weight

is stored and recorded. As with the settle timer, this

delay may have to be determined experimentally because it

is affected by the mechanical structure of the system. To

change the “Extend Dump” time press the UP or DOWN

navigation key to highlight the “Extend Dump” value and

then enter the desired time value.

When all of the time values are set as desired press the

ENTER key to store the values and return to the “Setup

Menu”. To cancel any changes press the SHIFT key and then

the /ESC key.

Zero Limit

The zero limit is a weight range used to approximate when

the scale is near 0 weight. If the zero limit is set to 50

lbs, then the zero range is from -50 to +50 lbs. Any time

the scale weight is within this range, the CBW system will

consider the scale to be close enough to zero to allow the

starting of weigh-hopper fill cycle or the completion of a

weigh-hopper dump operation. To enter the zero limit value,

press the ZERO LIMIT key. The display will show:

Enter desired weight value for “Zero Limit”. Press the

ENTER key to save the change and return to the “Setup

Menu”.

Trim Adjust.

The Trim Adjust. is the amount of additional material that

flows into the weigh-hopper after the upper garner or

hopper discharge gate is closed. This is sometimes referred

Page 4 of 28

to as material in suspension. This system is equipped with

an automatic adjustment of this amount. That is, if the

final weight is less than the required draft weight, the

system automatically decreases the TRIM weight which

increases the weight in the next draft. Likewise if the

final draft weight is more than the required draft weight,

the system automatically increases the TRIM weight

resulting in a decrease in weight on the next draft taken.

The value entered is only used on the initial draft or

weighment, which will be automatically adjusted by the

system as drafts are completed. Press the TRIM ADJUST key

and enter the initial value at the following screen.

Enter the desired weight value for the “Trim Adjustment”

and press the ENTER key to save the change and return to

the “Setup Menu”.

PRINT MODE

Press the PRINT MODE key to select the printer mode of

operation. The PRINT MODE will cycle through the available

modes of operation. If the PRINT MODE is “Normal” then the

total weights will be printed for each weighing cycle. If

the PRINT MODE is “Itemized” then the Gross, Tare and Net

weights will be printed for each draft, and then the total

weights will be printed for each weighing cycle.

The printer status is indicated on the main weight display

screen just above the START key. “Prt On” indicates that

the printer is on. “Prt Item.” indicates that an itemized

print out of the weights will be printed for each draft.

If no printer is connected or the printer is offline then

the status on the main weight display screen will be “Prt

Page 5 of 28

Off”. If the printer is offline no filling operation may be

started.
