WARNINGS
Warning Description
Possible
Cause
Possible
Actions
Coil Current
High
There is an internal
problem with either
the torque motor that
operates the
valve or with the
electronics used to
control the torque
motor. Depending on
the problem, the
valve is either unable
to operate properly or
is unable to achieve
full performance.
Internal fault.
Replace valve.
Coil Current Low There is an internal
problem with either
the torque motor that
operates the valve or
with the electronics
used to control the
torque motor.
Depending on the
problem, the valve is
either unable to
operate properly or is
unable to achieve full
performance.
Internal fault.
Replace valve.
Delta P High
The Delta Pressure
value exceeds the
delta pressure high
warning threshold.
Warning threshold
improperly configured.
Pressure regulator
adjusted too high.
Configure warning
threshold for value
appropriate to the
application.
Adjust pressure regulator.
Delta P Low
The Delta Pressure
value is below the
delta pressure low
warning threshold.
Warning threshold
improperly configured.
Valve is installed
backwards.
Configure warning
threshold for value
appropriate to the
application.
Verify that gas flow is in
the direction of the arrow
on the valve.
Electrical
Temperature
High
The valve internal
temperature has risen
too high to allow full-
power operation. The
torque available to
move the valve is
reduced and the
valve may not meet
specified
performance levels.
Valve ambient
temperature is too high.
Internal fault.
Reduce ambient
temperature.
Replace the valve.
Electronics
Temperature
High
The internal
electronics
temperature sensor
has failed to a high
value. The valve may
not reach specified
performance.
Internal fault.
Replace the valve.
