CHAPTER 7: TESTING
469 MOTOR MANAGEMENT RELAY – INSTRUCTION MANUAL 7–9
A2 METERING DATA ZV ANALOG INPUTS:
0 to 1 mA Analog Input
Z Alter the following settings:
S12 ANALOG I/O ZV ANALOG INPUT1 Z ANALOG INPUT1: “0-1 mA”
S12 ANALOG I/O ZV ANALOG INPUT1 ZV ANALOG INPUT1 MINIMUM: “0”
S12 ANALOG I/O ZV ANALOG INPUT1 ZV ANALOG INPUT1 MAXIMUM: “1000” (repeat for
Analog Inputs 2 to 4)
Analog output values should be ±0.01 mA on the ammeter. Measured analog input
values should be ±10 units.
Z Force the analog outputs using the following settings:
S13 TESTING ZV TEST ANALOG OUTPUT Z FORCE ANALOG OUTPUTS FUNCTION:
“Enabled”
S13 TESTING ZV TEST ANALOG OUTPUT ZV ANALOG OUTPUT 1 FORCED VALUE: “0%”
(enter desired percent, repeats for analog output 2-4)
Z Verify the ammeter readings as well as the measured analog input
readings.
