The side openings for the air to be measured are closed off on the VISIC50SF version
with fog dissipation.
If the cover is not placed on the measuring unit, error message F004 (heating) is active
because the power supply to the heating is interrupted.
Modbus-RTU is not available when a control unit is used.

2.3.1 Analog interfaces characteristics
The interfaces of the VISIC50SF provide 4 ... 20 mA signals. If an error exists on the
VISIC50SF, the relevant analog output changes to 1 mA.
The following formulas show the relation between the output current and the respective
measured variable:
Visibility:
Temperature:
2.3.2 Digital interfaces properties
If a device error is detected, 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
More information in Section Commissioning, see “Modbus-RTU (integrated in the
VISIC50SF standard version)”, page 40.
The switch to 1 mA only affects the analog output with a device error. The other analog
output continues to output a measured value between 4 ... 20 mA.
The analog interface can deliver a load of up to 500 Ohm.
The refresh rate is ≤1.6 seconds.

3.1 Safety information
NOTICE: Preventive measures for operating safety
The VISIC50SF is normally used together with control technology.
▸Should a malfunction occur on the VISIC50SF, ensure this cannot lead to conditions
dangerous for traffic or can hinder traffic.
NOTICE: The system operator is responsible for the operating safety of the
device when integrated in a system
▸Observe the connection values in Section, see “Technical data”, page 106, 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).
NOTICE: Mounting of the VISIC50SF may be carried out by competent 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.
NOTICE: SICK original mounting material is recommended for safe mounting of
the VISIC50SF.
CAUTION: The connection unit and the control unit do not have independent
main power switches.
▸In accordance with EN 61010, the following must be ensured before installation:
●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.
