1.1 Software history
For all GDC devices, the "Electronic Revision" (ER) is consulted to document the revision status
of the electronics according to NE 53. It is easy to see from the ER whether any fault repairs or
major changes to the electronic equipment have taken place and what effect they have had on
compatibility.
Changes and effect on compatibility
1 Downwards compatible changes and fault repair with no effect on operation (e.g. spelling
mistakes on display)
2-_ Downwards compatible hardware and/or software change of interfaces:
H
HART® Version 7
P PROFIBUS (pending)
F Foundation Fieldbus
M Modbus
X all interfaces
3-_ Downwards compatible hardware and/or software change of inputs and outputs:
I Current output
F, P Frequency / pulse output
S Status output
C Control input
X all inputs and outputs
4 Downwards compatible changes with new functions
5 Incompatible changes, i.e. electronic equipment must be changed.

1.2 Intended use
CAUTION!
Responsibility for the use of the measuring devices with regard to suitability, intended use and
corrosion resistance of the used materials against the measured fluid lies solely with the
operator.
INFORMATION!
The manufacturer is not liable for any damage resulting from improper use or use for other than

OPTISONIC 3400
Figure 3-16: Turning the display of the field housing version
The display of the field housing version can be turned in 90° increments.
1 Unscrew the cover from the display and operation control unit.
2 Using a suitable tool, pull out the two metal puller devices to the left and right of the display.
3 Pull out the display between the two metal puller devices and rotate it to the required position.
4 Slide the display and then the metal puller devices back into the housing.
5 Re-fit the cover and tighten it by hand.
CAUTION!
The ribbon cable of the display must not be folded or twisted repeatedly.
INFORMATION!
Each time a housing cover is opened, the thread should be cleaned and greased. Use only resinfree and acid-free grease.
Ensure that the housing gasket is properly fitted, clean and undamaged.

4.3 Power supply
WARNING!
When this device is intended for permanent connection to the mains.
It is required (for example for service) to mount an external switch or circuit breaker near the
device for disconnection from the mains. It shall be easily reachable by the operator and marked
as the disconnecting the device for this equipment.
The switch or circuit breaker and wiring has to be suitable for the application and shall also be in
accordance with the local (safety) requirements of the (building) installation
(e.g. IEC 60947-1 / -3)
INFORMATION!
The power terminals in the terminal compartments are equipped with additional hinged lids to
prevent accidental contact.
1 100...230 VAC (-15% / +10%), 22 VA
2 24 VAC/DC (AC: -15% / +10%; DC: -25% / +30%), 22 VA or 12 W
DANGER!
The device must be grounded in accordance with regulations in order to protect personnel
against electric shocks.

4 ELECTRICAL CONNECTIONS
100…230 VAC
• Connect the protective ground conductor PE of the mains power supply to the separate
terminal in the terminal compartment of the signal converter.
• Connect the live conductor to the L terminal and the neutral conductor to the N terminal.
24 VAC/DC
• Connect a functional ground FE to the separate U-clamp terminal in the terminal
compartment of the signal converter.
• When connecting to functional extra-low voltages, provide a facility for protective separation
(PELV) (VDE 0100 / VDE 0106 and/or IEC 364 / IEC 536 or relevant national regulations).
