Information:
This procedure is used in order to verify that the engine wiring between the junction box and the MECP Enclosure is correct. The following procedure should be performed after all of the wiring has been completed.Powerup Test
Pre-Powerup Test
Visually inspect all of the wiring for loose connections or incorrect connections.
Measure the resistance between "1A" and "2" in the control panel. Measure the resistance between "1B" and "2" in the control panel. Measure the resistance between "1C" and "2" in the control panel. Measure the resistance between "1D" and "2" in the control panel. Measure the resistance between "1E" and "2" in the control panel. All of the measurements should be at least 30 ohms.
Verify the power supply's polarity. Connect the 24 VDC to "TB-1". Connect the common ground to "TB-2".
The Engine Control Switch should be in the OFF/RESET position. The Fuel Control Switch should be in the OFF position. The Prelube/Start Switch should be in the RUN position.Powerup Test
Close circuit breaker 2. The Programmable Logic Controller should power up.
Close circuit breaker 4. The flex Input/Output and the engine speed switch should power up.
Close circuit breaker 3. The Marine Monitoring System's display should power up.
Close circuit breaker 1. The relay logic and miscellaneous circuits should power up.
Check the resistance between the following points:
"TB-109B" and "TB-109C" (Crankcase Pressure)
"TB-105B" and "TB-105C" (Lube Oil Pressure at Low Speed)
"TB-102B" and "TB-102C" (Lube Oil Pressure at High Speed)
"TB-107B" and "TB-107C" (Customer)
"TB-86B" and "TB-86C" (Summary Shutdown)
"TB-30A" and "TB-30C" (No Trip Alarm for the Circuit Breaker)
"TB-150B" and "TB-150C" (Fuel Control)Note: All of the measurements should be very close to zero.
Ensure that the display is communicating with the Programmable Logic Controller. The status of the PLC can be checked by selecting the "PLC Status Screen" on the PC display's main menu. The status of the PLC should be displayed.Prelube Test
Note: This test is only for intermittent prelube.
Turn the Engine Control System to the LOCAL position.
Temporarily disconnect the wiring to the prelube pump. The wires should be disconnected from terminals "TB-73" and "TB-72".
Turn the Prelube/Start Switch to the PRELUBE position.
Ensure that there is voltage between "TB-73" and "TB-72".Note: The voltage should be 24 VDC.
Connect a jumper wire between "TB-72" and "TB-2" in the junction box. The prelube light should be on.
Turn the prelube switch to the "Off" position.
Reconnect the wires from step 2.
Turn the prelube switch to the "Prelube" position.
The prelube pump should run, if air is supplied to the pump.Test for the Local Emergency Stop
Push the "E-Stop" button on the control panel.
Check the display in order to verify that an emergency stop has been activated. Ensure that the "Summary Shutdown" light has been illuminated.
Check the connections at both "TB-85" and "TB-82A" for 24 VDC with respect to terminal strip 2. This is done in order to verify that both the Air Shutoff Solenoid and the fuel control relay have been energized.
Turn the Engine Control Switch to the OFF/RESET position. Release the "E-Stop". The shutdown indicator should disappear.Test for the Remote Emergency Stop
Connect a jumper wire between "TB-84" and
Pre-Powerup Test
Visually inspect all of the wiring for loose connections or incorrect connections.
Measure the resistance between "1A" and "2" in the control panel. Measure the resistance between "1B" and "2" in the control panel. Measure the resistance between "1C" and "2" in the control panel. Measure the resistance between "1D" and "2" in the control panel. Measure the resistance between "1E" and "2" in the control panel. All of the measurements should be at least 30 ohms.
