9 Operation options for the head transmitter
For the head transmitter, display and operating elements are available locally only if
the head transmitter was ordered with an attachable display unit!
The transmitter's optional Bluetooth interface is only active if a display unit is not
attached or the CDI interface is not used for device configuration.
6.1.1 Measured value display and operating elements
Option: display TID10 with transmitter
The display may also be subsequently ordered
at any time after purchasing the transmitter,
see the 'Accessories' section in the Operating
Instructions for the device.

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

6 'Configuration locked'
symbol
7 Status signals
e.g. PV for a measured value from channel 1 or DT for the device

The 'configuration locked' symbol appears when configuration is locked
via the hardware.
Symbols Meaning
Error message "Failure detected"
An operating error has occurred. The measured value is no longer valid.
The display alternates betweenthe error message and "- - - -" (no valid
measured value present), see "Diagnostics events" section →37.
The display alternates betweenthe error message and "- - - -" (no valid
measured value present).
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 hardware settings for the fieldbus interface 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. →41
NOTICE
‣ESD - electrostatic discharge. Protect the terminals from electrostatic discharge.
Failure to observe this may result in the destruction or malfunction of parts of the
electronics.

12 Hardware settings via DIP switches
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.
3. Configure the DIP switch on the rear of the display accordingly. In general: switch to
ON = function enabled, switch to OFF = function disabled.
4. Fit the display onto the head transmitter in the correct position. The head transmitter
accepts the settings within one second.
5. Secure the cover back onto the terminal head or field housing.
Switching write protection on/off
Write protection is switched on and off via a DIP switch on the rear of the optional
attachable display. When write protection is active, parameters cannot be modified. A lock
symbol on the display indicates that the write protection is on. Write protection prevents
any write access to the parameters. The write protection remains active even when the
display is removed. To deactivate the write protection, the display must be attached to the
transmitter with the DIP switch switched off (WRITE LOCK = OFF). The transmitter adopts
the setting during operation and does not need to be restarted.
Turning the display
The display can be rotated 180° using the "DISPL. 180°" DIP switch. The setting is retained
when the display is removed.
