1. DESCRIPTION
DA
Rod-shaped sensor E650C-R for combined measurement of temperature
FI
and moisture in gutters and adjacent areas, such as flat roofs and
downpipes to be used with Elexant 650c-Modbus. Robust sensor made
NO
of brass, fully encapsulated. Extremely compact design with axial
cable outlet and threaded bolt for fixing in position. Mounting bracket
SV
for sensor E650C-R can be used with sensor height adjustment above
the mounting surface. The mounting bracket can be matched to the
CZ
mounting location by bending and then attached by gluing or soldering.
Two material versions of the bracket are available for compatible
LT
material combinations in gutter and flat roof applications.

regulations. The device must be installed in non-hazardous areas only.
ZH
Electrical connections are to be made by qualified electricians.
Attention: mistakes made when connecting the sensors Chemelex is
HU
not liable for any damage caused by faulty connection and/or incorrect
handling.
• The device may only be connected and serviced by authorised,
trained personnel.
• The device is designed to be connected to fixed cables only.
• When installing the device, make sure that high-voltage cables, such
as power supply cables, heating cables and cold leads do not come
into contact with low-voltage cables such as sensor cables.
• Local standards for electrical installation must be observed.
2.1 Sensor installation
Roof and gutter de-icing sensor E650C-R
Installation on the mounting bracket - fig. D1
A mounting bracket made of zinc is included in the package of the
E650C-R sensor. It is also available as a spare part accessory to be ordered
separately. There is also a separate variant of the bracket made of copper
available as a spare part accessory (to be ordered separately, not included
in the package of the E650C-R sensor). The mounting bracket enables better
fixing and positioning of the sensor.
Note for material compatibility: If the mounting bracket is to be used in a
copper gutter, the variant E650C-R-BRACKET-CU made of copper is available
for this case. Only with gutters made of plastic there are no material
compatibility restrictions and E650C-R-BRACKET-ZN can be used.
When installing the sensor in the bracket, first bend the rear part of the
bracket to fit the rear part of the sensor onto it, then unscrew the plastic
screw and remove one of the plastic washers and bend the front part
of the bracket, then insert the thread into the hole created by bending
the bracket, put the plastic washer back on and screw in the screw. In
this way, the front of the bent bracket should be between the two plastic
washers. The plastic washers, screw and sensor support rings are
included in the kit and can be found already mounted on the sensor (they
are all UV resistant). Next, attach the mounting bracket to a gutter or flat
roof. The mounting bracket can be attached to gutters or flat roofs using
