Verify that the “AC Mains” LED on the PDU front panel is ON

Verify that the Emergency Stop on the E-Stop Module is deactivated (24V_ON LED must be lit). Rotate the Emergency Stop button clockwise to release the EMERGENCY STOP button, press the Start button to enable the PDU main power contactor, and ensure that the Start/Stop button is lit.

Verify that the signal harness on the rear panels of the E-Stop Module and PDU (P1 connector) is correctly plugged in.

Verify that all power bars inside the test bench are plugged in (double-check for any loose connection) and turned ON (indicator light should be lit on power bars)

Verify that the power switch is turned ON (I) on the PDU rear panel.

For test bench models with more than one DC power supply, verify that the 3-phase connections are interleaved from one power supply to another to ensure balanced three-phase currents, as documented in OP1400PR PHIL Prime Test Bench Series Installation

Verify that the current limits of the DC power supplies are properly set. Refer to DC Power supplies - Functional overview.

Verify that the DUT channel is locally Enabled and remotely activated (the light between the Start/Stop button must be lit)

Verify that the wiring from the amplifier to the DUT interface is correct, refer to https://opal-rt.atlassian.net/wiki/pages/createpage.action?spaceKey=pssdd&title=%5BNEW%5D%20-%20OP1400PR%20PHIL%20Prime%20%20Test%20Bench%20Series%20Operation&linkCreation=true&fromPageId=2365587498

Verify that the SFP cable is correctly connected between the amplifier (right SFP port) and the simulator

Verify that the SFP communication link has been correctly configured in RT-LAB and that the model is running (measurements coming from the amplifier should have a little noise)

Verify that the OP8110 amplifier unit is turned ON (the light inside the power-on button on the front panel is green), refer to problem OP8110 Amplifier does not turn ON if necessary.

Verify that the SFP cable is correctly connected between the amplifier (right SFP port) and the simulator

Verify that the SFP communication link has been correctly configured in RT-LAB and that the model is running (measurements coming from the amplifier should have a little noise)

Verify that the OP8110 amplifier unit is turned ON (the light inside the power-on button on the front panel is green), refer to the problem “OP8110 Amplifier does not turn ON” if necessary.

Power down the DC supply and wait for 5 minutes before reenabling the precharge sequence, refer to OP8110 Power Stage (DC Precharge section).

Verify that the SFP cable is correctly connected between the amplifier (right SFP port) and the simulator

Verify that the SFP communication link has been correctly configured in RT-LAB and that the model is running (measurements coming from the amplifier should have a little noise)

Try clicking on the DISABLE button before retrying the ENABLE button (GUI synchronization issue that arises when trying to enable outputs too rapidly).

Verify that the auxiliary supply harnesses (one for OP8110-3, two for OP8110-6) are correctly plugged in on the OP8110's 12 V AUX connectors on the rear panel.

Verify that the auxiliary supply harness on the PDU rear panel is correctly plugged in

Verify that the Emergency Stop on the E-Stop Module is deactivated (the 24 V ON LED must be lit), and rotate the Emergency Stop button clockwise if not the case, to release the EMERGENCY STOP button if necessary.

Verify that the signal harness on the rear panels of the E-Stop Module and on the rear panel of the PDU (P1 connector) are correctly plugged in.

Verify that the 24 V ON LED on the PDU front panel is lit.

Verify that the front panel 24V ON light is lit, refer to “LP or HP Bus Bar is not supplied (24 V ON light is not lit)” if necessary.

Enable the DUT by pressing the Start button - the button light should start blinking.

Activate the DUT remotely - the button light should be lit continuously.

Verify that a DB37 harness is connected between the Bus Bar DI connector (rear panel) and the appropriate digital output connector of the simulator.

Verify that the digital output module of the simulator is correctly configured (a loopback test can be done with the DB37 harness looping back to a digital input module).

Verify that the signal harness on the rear panels of the E-Stop Module and on the rear panel of the PDU (P1 connector) are correctly plugged in.

Verify that all power bars inside the test bench are plugged in (Double Check for any loose connection), and turned ON (indicator light should be lit on power bars).

Verify that the power switch is turned ON (I) on the PDU rear panel.

Verify that the 24 V ON LED on the PDU front panel is lit
