Page 9: Installation Of The Pem4 Touch Screen
6.3 INSTALLATION OF THE PEM4 TOUCH SCREEN 1. Install the PEM4 touch screen in a control cabinet or control panel in the ECR or on the bridge, where it will be free as possible from moisture, large fluctuations of temperature and particularly of vibration shock. - Page 10 ® 5. Only applicable if an additional (second) touch screen is connected to the T-Sense system. Additional touch screens are connected to the system as described in Figure 5. For the use of two PEM4 screens a Ethernet switch is necessary.
- Page 11 6. IP settings of the PEM4 display In order to have no malfunction of the system the IP settings of the PEM4 display have to be set up correctly. The next steps will explain how to adjust the IP settings of the system. Switch off the power supply of the PEM4 display.
- Page 12 Ensure the IP address is 168.0.0.110 for the first PEM4 display. In case a second PEM4 display is installed the second screen should have IP address 168.0.0.111. If this is correct press “Next”. Set the DNS address to 255.255.255.0 and press “Done”. The screen below will appear. Press “Confirm”...

7.5.2 Propulsion screen Figure 8 – Propulsion screen This page is showing the average propulsion data over the last 1, 4 and 24 hours. When the propeller shaft is rotating the PEM4 is continuously recalculating these average values. In case the propeller shaft is not rotating the average values stay as they are. - Page 17 7.5.3.1 Settings menu, torque inversion Figure 10 – Settings menu, torque inversion When the touch screen is showing a negative torque value, when sailing ahead, you are able to convert this negative value to positive by pushing the “Standard” button once. “Standard” will now change to “Inverse”.

Page 19: Method Of Calculations
7.6 METHOD OF CALCULATIONS Shaft power is calculated from the measured torque and the revolutions of the shaft. Shaft power ∙ ∙ 9.945 = Shaft power [kW] = Torque [kNm] = rotations per minute [rpm] Total energy is calculated from the integrating shaft power over time ... -
Page 20: Maintenance
If the PEM4 stops working completely contact VAF Instruments for instructions. VAF Instruments is working with a RMA (return material authorisation), in the event the PEM4 has to be sent back for repair, you can contact VAF Instruments, by email: service@vaf.nl... -
