Removing/Replacing Sensor Assemblies

DANGER

EXPLOSION HAZARD: To replace the sensor you must completely remove the flow computer

from its installation location and move it to a non-hazardous area. Ensure the area is non-

hazardous before disconnecting the flow computer.

CAUTION

MAY CAUSE INJURY TO PERSONNEL OR DAMAGE EQUIPMENT

Because I/O, ground, and other wires enter the flow computer through conduit fittings and then

connect to the boards inside, a qualified technician must disconnect all wiring coming into the

flow computer and pull it out through the conduit fittings in order to replace the sensor

assembly.

You must then reinstall all boards and modules and completely rewire the unit.

If not already done, be sure to label all wires before disconnecting so you can identify them later

during the rewiring process.
