 13 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 screen 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 lock
symbol on the display indicates that write protection is on. Write protection prevents any
write access to the parameters. Write protection remains active even when the display is
removed. To deactivate 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.
Hardware locking for the TMT85 is disabled (HW_WRITE_PROTECTION = 0) as soon
as the display is removed. When the displayed is attached, the value set at the DIP
switch is updated on the device.
Turning the display
The display can be rotated by 180° via the DIP switch. The setting of the DIP switch is
saved and displayed in the Display Transducer Block via a read-only parameter
(DISP_ORIENTATION). The setting is retained when the display is removed.
