Next, calibrate the external 4...20 mA signal conditioners.
1. Set a digital multimeter to mA and place it in line with the signal
conditioners. If the output of the conditioner is terminated, use the meter
as a load.
2. Assign a parameter to the Analog Output port you are calibrating. This
parameter must be configurable from minimum to maximum for test
purposes only, for example: IDC Command Test. See previous page on
assigning an output.
3. Set IDC Command Test to 0.000 pu. This is the minimum. Adjust the
Zero adjustment screw on the isolator to read 4 mA.
4. Set IDC Command Test to 1.500 pu. This is the maximum. Adjust the
Span adjustment screw on the isolator to read 20 mA.
5. Repeat the process until you complete the adjustments.
6. Set IDC Command Test to 0.750 pu to ensure you read 12 mA (Half-
scale). Set IDC Command Test to 0.000 pu.
7. Assign the required parameter to the Analog Output port we have
calibrated.
8. Save all changes to NVRAM.
Configurable Alarms
Test the external faults by lifting the wires to all external warning / fault inputs
while running in system test mode. These wires terminate at the Digital I/O
boards. Opening the circuit at any point will verify the external fault’s
configuration and functionality. However, it is preferable to actually force the
trips from the source. If that is not possible, lift the wire at the protective device.
ATTENTION: Do not short the lifted wire to ground when testing the circuit or
damage will occur to the Digital I/O board and possibly weld the equipment’s
trip contact.
