Safety functions
Hold mode
Display:
The Hold mode is a safety state during configuration and cali-
bration. The loop current is frozen (Last) or set to a fixed value
(Fix).
If the calibration or configuration mode is exited, the transmit-
ter remains in the Hold mode for safety reasons. This prevents
undesirable reactions of the connected peripherals due to
incorrect configuration or calibration. The measured value and
“HOLD” are displayed alternately. The transmitter only returns
to measuring mode after enter is pressed and 20 seconds have
passed.
Configuration mode is also exited automatically 20 minutes
after the last keystroke (timeout). The transmitter returns to
measuring mode.
Timeout is not active during calibration.
Behavior of output signal:
Last: The loop current is frozen at its last value.
Recommended for short configuration procedures.
The process should not change decisively during
configuration. Changes are not noticed with this
setting!
Fix: The loop current is set to a value that is noticeably
different from the process value in order to signal the
control system that the transmitter is being worked at.
See Configuration, Pg 51.
