The side openings for the air to be measured are closed off on the VISIC100SF version
with fog dissipation.
If the cover is not placed on the measuring unit, error message F004 (heating) is active
because the voltage supply to the heating is interrupted.
Modbus®RTU is not available when a TAD control unit is used.

PRODUCT DESCRIPTION
2.3 Interfaces
●Standard:
– 3 analog interfaces for measured value output
– 2 digital interfaces for maintenance requests or malfunction messages
– RS-485: Either Modbus®RTU or SICK bus to the TAD control unit
●Optional:
– PROFIBUS DP-V0
2.3.1 Analog interfaces characteristics
The interfaces of the VISIC100SF provide 4 ... 20 mA signals. If an error exists on the
VISIC100SF or when the measured value underflows the lower measuring range limit, the
relevant analog output switches to 1 mA. If the upper measuring range limit is exceeded,
the relevant analog output switches to 23 mA.
The following formula shows the relation between the output current and the respective
measured variable:
2.3.2 Digital interfaces properties
If a device error is detected or a measured value is outside the measuring range, an error is
signaled via the malfunction relay. If no device error exists, the malfunction relay is in a
closed state. The relay opens when an error occurs.
2.3.3 Modbus®-RTU interface characteristics
see “Modbus® RTU (integrated in the VISIC100SF standard version)”, page 39.
The switch to 1 mA only affects the analog output with a device error. All other analog
outputs continue to output a measured value between 4 ... 20 mA.
The analog interface can drive a load resistance of up to 500 Ohm.
The refresh rate is ≤1.6 seconds.

3.1 Safety notes
3.2 Material required
Table 1: Mounting material
Table 2: Installation material
NOTE: Preventive measures for operating safety
The VISIC100SF is normally used together with control technology.
▸Should a malfunction occur on the VISIC100SF, ensure this cannot lead to
conditions dangerous for traffic or can hinder traffic.
NOTE: The system operator is responsible for the operating safety of the
device when integrated in a system
▸Observe the connection values from Section, see “Technical Data”, page 103, when
integrating the device in a system.
WARNING: Preventive measures during mounting and installation
▸Observe the generally applicable regulations for protective clothes in tunnels.
▸Observe the regulations for personal safety (e.g., lane closure, warning devices).
NOTE:
Mounting of the VISIC100SF may be carried out by qualified persons only who, based
on their device-specific training and knowledge of the device as well as knowledge of the
relevant regulations, can assess the tasks given and recognize the hazards involved.
NOTE:
Original SICK mounting material is recommended for safe mounting of the VISIC100SF.
CAUTION: The connection unit and the TAD control unit do not have
independent main power switches.
▸Ensure the following before installation in accordance with EN 61010:
●A main power switch is available in the tunnel.
●Service personnel can easily access the main power switch.
●The main power switch is marked as disconnecting device.
