New HIDS Drum Scales!
Click Here to Learn More!Yes, the unit can be setup so the output controls a set of lights to indicate how much product is in the vessel. Below is an example of doing the mapping and setpoint setup in an HI 4050 unit to control three lights. This could be applied to the HI 4060, the HI 3030, or HI 3010. The below example uses the DIO option in the HI 4050 unit, however, this could be mapped as a boolean output to a network connection like a PLC also.
Application: Three lights, green, yellow, red; to come on at different weight readings. Need the green light to indicate when the weight is above 7.5, the yellow to indicate that the weight is above 4.5, but less than 7.5, and the red to indicate that the weight is above 2.5, but less than 4.5.
Wiring:
Hook up green light to DIO output #1
Hook up yellow light to DIO output #2
Hook up red light to DIO output #3
The instrument setup that I came up with for the stack lights to work as described is:
Setpoint #1: Mode= Gross weight; Type = Gain in Weight; Target = 7.5; Preact = 0; Deadband = 0.
Setpoint #2: Mode= Gross weight; Type = Gain in Weight; Target = 4.5; Preact = 0; Deadband = 0.
Setpoint #3: Mode= Gross weight; Type = Gain in Weight; Target = 2.5; Preact = 0; Deadband = 0.
Mapping:
HO0.0=+HI2.0
HO0.1=+HI3.0*~HI2.0
HO0.2=+HI4.0*~HI3.0
Explanation:
HO0.0 is DIO output #1.
HO0.1 is DIO output #2.
HO0.2 is DIO output #3.
HI2.0 is output for setpoint #1
HI3.0 is output for setpoint #2
HI4.0 is output for setpoint #3
HO 0.0 will turn on when setpoint #1 is true. This will turn on the green light.
HO0.1 will turn on when setpoint #2 is true and setpoint #1 is false. This will turn on the yellow light.
HO0.2 will turn on when setpoint #3 is true and setpoint #2 is false. This will turn on the red light.
This will allow only one light to be on at any time.
