Handling Precautions:
ESD - electrostatic discharge. Protect the terminals from electrostatic discharge.
Failure to observe this may result in destruction or malfunction of parts of the
electronics.

Figure 6-3. Hardware settings via DIP switches
1: Connection to head transmitter
2: DIP switch (1 to 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.
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 key
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 device must be restarted with
the display attached and the DIP switch deactivated (WRITE LOCK = OFF).
Turning the display
The display can be rotated 180° using the “DISPL. 180°” DIP switch. The setting is retained
when the display is removed.
6-2. Configuration of transmitter and HART
®
protocol
The transmitter and measured value display are configured via the HART
®
protocol.
The configuration of device-specific parameters is described in detail in the User's Manual.
