Using The Setpoint Feature on EZIII Indicators


Setpoint is a feature that allows the operator to set a gross weight that will activate the +12VDC Relay Output on PIN 4 of the J901 power connector. This feature is commonly used for automations or visual/audible notifications. An additional option determines how much change of weight will be required before the relay signal will switch states again.  This value must be lower than the Setpoint and can be used as a solenoid shutoff value in an automated system. The weight value used for Setpoint is the Serial Gross Weight which can be isolated from the displayed gross weight to prevent unintended zeroing errors or can coincide with the displayed gross weight.

D.A.N. 406 – RELAY

This must be set to SETPNT.

D.A.N. 423 – SETPNT

Enter the value at which the 12V relay will activate.

D.A.N. 424 – SETCHG

Enter the amount of weight change that is needed to de-activate the 12VDC relay. Value must be lower than the Setpoint.

D.A.N. 425 – SETDEL

Enter a delay value in seconds (0-10) that must expire before the relay will switch states. This prevents rapid toggling of the relay if the weight value is fluctuating at the Setpoint.

D.A.N. 426 – SETOUT

OVER The relay will turn on when the weight is equal to or exceeds the Setpoint.

UNDER The relay will turn on when the weight is equal to or below the Setpoint value minus the Set Change value.

D.A.N. 427 – SETCTR

This counter will increment each time the setpoint is triggered. Use this setting to view the number of triggers or to manually enter the current value.

D.A.N. 219 – ZEROUT

Serial Gross Weight value. This is the value that will be used to trigger the Setpoint.  When system is empty, enter D.A.N. 219 and hold the ZERO key to set the Serial Gross Weight to zero.  By default, the Serial Gross Weight will run independently from the displayed gross weight.  If the user inadvertently zeros the scale, the Serial Gross Weight value will not shift.  If desired, this can be set to match the displayed gross weight by turning on D.A.N. 249. This will zero balance the Serial Gross Weight any time the scale display is zeroed via the front panel.

 


On scales without a keypad, most of these settings can be found in Menu 4.  ZEROUT can be found in menu 2.  Hold Net/Gross and ON until a message scrolls across the screen then press select until the desired menu is shown.  Press ON to enter the selected menu.

The Setpoint feature can be used for multiple automation or notification purposes. 

Some examples of Setpoint applications:

 

Example #1: Trigger a light or alarm when a bin weight exceeds 10,000 lbs.

DAN 406 – SETPNT

DAN 423 – 10,000

DAN 424 – 1000

DAN 425 – 3

DAN 426 – OVER

When the Serial Gross Weight is greater than or equal to 10,000 lbs, the 12VDC relay will activate and turn on the light after a 3 second delay.  Once the bin weight drops below 9,000 lbs the relay will de-activate after a 3 second delay.

 


Example #2: Trigger a bin to fill automatically when its weight is below 100 lbs and stop filling when the weight equals 1000 lbs.

DAN 406 – SETPNT

DAN 423 – 1000

DAN 424 – 900

DAN 425 – 1

DAN 426 – UNDER

When the Serial Gross Weight is above 1000 lbs the relay will be de-activated.  Once the weight drops below 100 lbs, the relay will activate until the weight is once again above 1000 lbs.
