Item no. Function Description
1 Displays the TAG TAG, 32 characters long.
2 'Communication' symbol The communication symbol appears when read and write-accessing via
the fieldbus protocol.
3 Unit display Unit display for the measured value displayed.
4 Measured value display Displays the current measured value.
5 Value/channel display
DT, PV, I, %
e.g. PV for a measured value from channel 1 or DT for the device
temperature
6 'Configuration locked'
symbol
The 'configuration locked' symbol appears when configuration is locked
via the hardware.
7 Status signals
Symbols Meaning
Error message "Failure detected"
An operating error has occurred. The measured value is no longer valid.
The display alternates between the error message and "- - - -" (no valid
measured value present), see "Diagnostics events" section→ 37.
Detailed information on the error messages can be found in the
Operating Instructions.
"Service mode"
The device is in service mode (e.g. during a simulation).
"Out of specification"
The device is being operated outside its technical specifications (e.g.
during warm-up or cleaning processes).
"Maintenance required"
Maintenance is required. The measured value is still valid.
The display alternates between the measured value and the status
message.
Local operation
You can make various hardware settings using miniature switches (DIP switches) on the
rear of the optional display.
The user has the option of ordering the display with the head transmitter, or as an
accessory for subsequent mounting. → 42

12 Hardware settings via DIP switches
1: Connection to head transmitter
2: DIP switches (1 - 64, SW/HW, ADDR and SIM = simulation
mode) no function for this head transmitter
3: DIP switch (WRITE LOCK = write protection; DISPL. 180° =
switch, turn the display monitor 180°)
Procedure for setting the DIP switch:
1. Open the cover of the terminal head or field housing.
2. Remove the attached display from the head transmitter.
