Fault Code Latch Description Action
after a lightning strike or large
voltage transient on the power
or signal lines to the unit.
F004 EEPROM Error Latch In the event of an EEPROM
error, the user must recycle
the power to potentially clear
the error. After power reset,
the following may occur:
1. Unit returns to normal.
a. This indicates the
EEPROM writing did not
keep up to changing
events or the write cycle
is too fast.
2. Unit goes to sensor faults. The
user must recalibrate after 1-2
minutes sensor warm up.
a. This means the non-
critical part of the
EEPROM was corrupted.
b. This is probably caused
by an event-logging
problem.
c. There is a possibility any
of the following may be
corrupted: Event logging
data, Modbus settings,
HART settings,
Calibration information.
3. Unit returns to F004.
a. This is a critical error.
This fault occurs when an
attempt to verify the
setup/calibration
parameters just written to
the EEPROM memory
fails.
b. Reset transmitter
settings to reload the
factory default to the
EEPROM. Sensor
recalibration is required
after this operation. All
settings including, but
limited to, alarm/warning,
setpoint, relay, Modbus,
AO output level should be
verified and
reprogrammed.
