Procedure
1. Switch off the pressure sensor to be replaced (P sensor 1 in the
example). Also refer to section Operation.
2. Wait until the ON/OFF key is no longer subdued.
3. Disconnect the pressure sensor from the CAN bus.
4. Connect the CAN bus cable to the new pressure sensor.
5. Also refer to Fig. 7‐13 for information on T-Tap and CAN bus cables with
hexagon nut.
6. Refer to Pressure Sensor Setup in the section Operation for information
on how to proceed.
NOTE: If during work on the CAN bus errors occur that have no readily
apparent cause (red indication lamps) or the unit shuts down, switch the
melter off then on again with the main switch.
