ARS31(Pro)-UMB Operating Manual V9/03.2017 3 Differences between ARS31Pro-UMB/ARS31-UMB ARS31Pro-UMB compared with ARS31-UMB possesses the following features: Measurement of threat of icing by means of a direct measurement or freezing temperature. Exact measurement of road surface temperature with an external temperature sensor.
Inverse-polarity protection 4.1 Method of operation ARS31Pro-UMB/ARS31-UMB ARS31Pro-UMB/ARS31-UMB determines the freezing temperature of a liquid on the road surface by means of active cooling and heating. The Sensor allows precise determination of the freezing temperature in the absence of accurate knowledge of the type or mixture of salt.
4.2 Additional features of ARS31Pro-UMB In addition, ARS31Pro-UMB determines the threat of icing as follows: for a dry road – by cooling to an adjustable temperature value (∆ T1); for a wet road - by comparing the measured freezing temperature with the road surface temperature while taking account of the set temperature value (∆...
Dp = 6 cm. A slit of width W = 2 cm and depth Dp = 5 cm is cut into the road for the cable. For ARS31Pro-UMB the external sensor requires an additional hole of diameter Dm > 9 cm and depth Dp = 5 cm.

Per core 100 m cable results in a loop resistance of 7.3 Ω. By parallel connection of 4 cores results in a loop resistance of 7.3 Ω / 4 = 1.83 Ω Figure 4: Example of an Extension Box G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany...

Operating Manual V9/03.2017 5.4 Commissioning and testing After the device has been installed and connected correctly, the ARS31Pro-UMB/ARS31- UMB is initialized and measurement begins. The first measurements are available after approximately 1 minute; after approximately 20 minutes, the measurements for freezing temperature and saline concentration / threat of icing are available (provided that the ambient conditions allow such measurements).
The threads of the fixing screws must be greased. First the screws are attached loosely and then tightened cross-wise (torque 2 Nm). G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany...
See Section 3.3 Installation – Connecting the cable 6.2.1.1 Power supply The ARS31Pro-UMB/ARS31-UMB power supply is 24 VDC ± 10% (for a cable length up to 15 meters). For cable lengths over 15 meters see table below. The supply voltage must not exceed the value of 28 VDC.
Page 21
The data and power supply cables are connected via a 4-pole terminal block. Cable type LI-2YCYv2X2X0.5 is used. Cable labeling on the pins is based on DIN 47100. The screened cable must be laid to the ground circuit connector in the control panel. G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany...
After loading an ARS31PRO-UMB configuration, all relevant settings and values can be adjusted. If several ARS31PRO-UMB devices are operated on a UMB network, the ID must be changed before connection to the network, as each device requires a unique ID. IDs are allocated in ascending order, beginning with number one.

If this function is disabled, the dry threshold as set using the UMB-Config Tool applies. If this value is too high, the ARS31Pro-UMB measures during dry conditions, which may lead to incorrect measurements caused by condensation on the sensor element.

After the activation of the freezing temperature limit, the smoothed freezing temperature can be transitional-wise under the temperature limit (if the freezing temperature directly before the change was under the opposed limit). G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany...

You can activate the measurement polling channels for the UMB-Config-Tool by clicking on the respective channel. This setup has no influence on the channels which can be queried by the user software.

RS485 interface with the aid of the ISOCON-UMB. The bus is not terminated with a resistor due to dissipation in the sensor. The use of PC software from Lufft for purposes of maintenance and diagnosis makes an RS485-RS232 or RS485-USB converter superfluous.

However, this only makes sense if there is only one device of this class on the bus. 8.1.3 Examples for creating addresses If, for example, an ARS31PRO-UMB/ARS31-UMB is to be given device address ID 0001, this is done as follows: Class ID for ARS is 4d = 4h Device ID is e.g.
+ 1 (LSB first mode) Start value: FFFFh (Attention: Contrary to earlier Lufft protocols, the start value for CRC calculations is not 0h but rather FFFFh in accordance with CCITT) Further information is available in the description of a CRC calculation in UMB Protocol.
