control) or as an I/P (pressure control).

Drive Signal
Drive Signal (DRIVE_SIGNAL [53]) indicates the drive signal, as a percentage of the maximum drive available, going to
the I/P converter from the printed wiring board. In most applications, the drive signal ranges between 50% and 75% of
the maximum drive signal.
Temperature
Temperature (TEMPERATURE [48]) displays the internal temperature of the instrument in either degrees Fahrenheit or
Celsius.
Cycle Counter

must occur after the deadband has been exceeded before it can be counted as a cycle.

accumulator only increments when travel exceeds the deadband. Then the greatest amount of change in one
direction from the original reference point (after the deadband has been exceeded) will be added to the Travel
Accumulator.
