Siemens Frost detector‘ A6V10432022_en--_e
Smart Infrastructure 2021-04-20
On the hot side of the air heating coil.
Direct mounting
Fit the housing (by using the 2 fixing holes) to the wall of the air heating coil. Intro-
duce the capillary tube in the air duct and protect it by using the rubber grommet
supplied with the unit (refer to "Accessories").
When fitting the frost detector inside the air duct: secure the housing to the inner
wall of the air heating coil and lead the capillary tube through one of the lateral
grooves.
Direct mounting, with test loop for functional test
Fit the housing (by using the 2 fixing holes) to the wall of the air heating coil and
lead the capillary tube through one of the lateral grooves.
Bend the capillary tube to form a test loop, introduce it to the air duct and protect it
by using the enclosed rubber grommet (refer to "Accessories").
This mounting method is not recommended when the ambient temperature at the
external test loop may fall below the temperature at the measuring location in the
air duct (the measuring signal of the sensing element always represents the lowest
temperature, no matter where it occurs along the capillary tube!).
With mounting flange (refer to "Accessories")
This mounting method is suited for air ducts having an insulation of up to 70 mm.
Fit the mounting flange to the wall of the air heating coil and introduce the capillary
tube through the flange in the air duct.
Coil the capillary tube evenly across the entire cross-sectional area of the air heat-
ing coil and attach it to the coil with the help of the clamps, maintaining a spacing
of 40 mm (refer to "Accessories").
The capillary tube must not be sharply bent. The bending radius should be as great
as possible.
The low voltage terminals are protected against wiring errors with own voltages up
to AC 24 V.
The terminals are not protected against wiring errors with AC 230 V mains voltage.
The frost detector must be commissioned and set as specified in the instructions
supplied with it. No settings are required on it (factory setting = 5 K).
A test loop allows the function of the frost detector to be checked with the help of a
mixture of ice and water or ice spray. This way, frost can be simulated, also
allowing the plant to be checked under frost conditions (switch-off functions).
The menu includes a "Frost test" function, meaning that frost can be simulated,
also allowing the plant to be checked under frost conditions (switch-off functions).
The device is considered an electronic device for disposal in accordance with the
European Guidelines and may not be disposed of as domestic garbage.
 Dispose of the device through channels provided for this purpose.
 Comply with all local and currently applicable laws and regulations.
