SPAN FAIL

The span value, set with the local span adjustment button, exceeds the maximum range down allowed for a particular range, or the pressure sensed by the transmitter exceeds the sensor limits.

KEYS DISABL

This message appears during reranging with the integral zero and span buttons and indicates that the transmitter local zero and span adjustments have been disabled. The adjustments have been disabled by software commands from the HART Communicator or AMS. Keys are not detected when write protect jumper is active. See “Security (Write Protect)” on page 2-5for information on the software lockout.

STUCK KEY

The zero or span button is stuck in the depressed state or pushed too long.
