Replacing the Regulator and Fuses in the
Monitor
The FlowHawk monitor contains a removable power regulator
secured to a special dome that resides inside the monitor enclosure
and is attached to the monitor top. If a regulator failure occurs, it
typically involves a bad fuse on the regulator board corresponding
to communications or sensors. However, monitors with regulators
manufactured prior to 2012 do not possess replaceable fuses.
Therefore, fuse failures that occur with these units require
replacement of the whole regulator/dome assembly. All monitors
that require a new regulator must be returned to IETG for
regulator/dome assembly replacement. Do not attempt to exchange
a regulator in the field!
Monitors with regulators manufactured as of January 2012 contain
replaceable fuses that attach to the regulator board on the inside of
the dome. This new design allows for the replacement of individual
fuses when failures occur, eliminating the need to send a monitor to
IETG for an entire regulator/dome assembly exchange. Refer to the
Troubleshooting section beginning on page 8-38 to identify whether
a regulator or fuse may be the source of a particular problem that
has arisen within the FlowHawk system.
Note: Monitors manufactured as of 2012 contain
regulators with replaceable fuses.
