 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.
