CHAPTER 7: TESTING
The 469 specification for analog input and analog output accuracy is ±1% of full scale.
Perform the steps below to verify accuracy. Verify the Analog Input +24 V DC with a
voltmeter.
4 to 20 mA Analog Input
Alter the following settings:
S12 ANALOG I/O ANALOG INPUT1 ANALOG INPUT1: “4-20 mA”
S12 ANALOG I/O ANALOG INPUT1 ANALOG INPUT1 MINIMUM: “0”
S12 ANALOG I/O ANALOG INPUT1 ANALOG INPUT1 MAXIMUM: “1000” (repeat this
value for Analog Inputs 2 to 4)
Analog output values should be ±0.2 mA on the ammeter. Measured analog input
values should be ±10 units.
Force the analog outputs using the following settings:
S13 TESTING TEST ANALOG OUTPUT FORCE ANALOG OUTPUTS FUNCTION:
“Enabled”
S13 TESTING TEST ANALOG OUTPUT ANALOG OUTPUT 1 FORCED VALUE: “0%”
(enter desired value in percent; repeat for Analog Outputs 2 through 4)
Verify the ammeter readings as well as the measured analog input
readings.
For the purposes of testing, the analog input is fed in from the analog
output (see FIGURE 7–1: Secondary Injection Test Setup on page 7–2).
