Checklist For Commissioning And Testing - Protrol IPC4020 Manual

Checklist for Commissioning and Testing

1. Check the polarity and level of the auxiliary voltage before powering up the IPC402x.
2. Connect to IPC402x via the Ethernet or USB interface. Log in as config or admin.
3. Open the Site manager subtab.
4. Test binary inputs by applying 24 VDC at one input at a time. Verify that:
a. The correct LED on the unit lights up.
b. The corresponding LED symbol in the Site manager is activated.
c. Corresponding indication message is sent via the selected remote interface.
5. Check Enable Manual control of outputs box in Site manager. If required, disconnect the
outputs from external objects. Verify that:
a. The correct LED on the unit lights up when activated in Site manager.
b. The correct output is activated. Measure the resistance across the output on
c. If possible, activate the output via the remote interface.
6. If the station is in operation, the phase currents connected and with a measurable current,
check that:
a. The correct amplitude is displayed in the Site manager.
b. The currents are symmetrically presented in Site manager. If the amplitudes are
c. Create a disturbance file and check that the phase sequence is the expected one.
d. Measurement values are displayed correctly in the remote control center.
7. To test overcurrent and earth fault detector functions:
a. Inject current with a one or three phase instrument. Check the indications for each
b. With a current connected in counter phase to two inputs, both overcurrents and
c. If no current injection instrument is available and if the station is in operation with

if possible, in the remote control end. See Figure 18.
earth faults can be verified. For testing of earth faults, typically apply 0.5 A and
then short-circuit one of the phases swiftly on a terminal or directly on the plug-in
contact of the device.
