1. Alter the following setpoints:
S11 ANALOG I/O\ANALOG INPUT1\ANALOG INPUT1:
0-1 mA
S11 ANALOG I/O\ANALOG INPUT1\ANALOG INPUT1 MINIMUM:
0
S11 ANALOG I/O\ANALOG INPUT1\ANALOG INPUT1 MAXIMUM:
1000 (repeat for analog inputs 2 to 4)
2. Analog output values should be ±0.01 mA on the ammeter. Measured analog input values should be ±10 units. Force
the analog outputs using the following setpoints:
S12 TESTING\TEST ANALOG OUTPUT\FORCE ANALOG OUTPUTS FUNCTION:
Enabled
S12 TESTING\TEST ANALOG OUTPUT\ANALOG OUTPUT 1 FORCED VALUE:
0% (enter %, repeat for outputs 2 to 4)
Verify the ammeter readings as well as the measured analog input readings. View the measured values in:

To verify the functionality of the output relays, perform the following steps:
1. Using the setpoint:
S12 TESTING\TEST OUTPUT RELAYS\FORCE OPERATION OF RELAYS:
R1 TRIP
select and store values as per the table below, verifying operation
R6 Service relay is failsafe or energized normally, operating R6 causes it to de-energize.
