Instruction

4.0 Installation of temperature sensors

Handle the temperature sensors carefully!
The sensor cables are fitted with coloured type labels:
Red (TH): sensor in hot line,
Blue (TC): sensor in cold line
Make sure the sensors are mounted symmetrically (both directly
immersed, or both installed in a pocket). The maximum cable length
is 10 m. The connecting cables must not be shortened or extended.
The free temperature sensor can be installed in a ball valve /adapter
or in a conformity tested pocket for this type of sensor. Ensure that the
temperature sensors are permanently connected during operation.
For installation in a ball valve (same for adapter), a 4-piece coupling
set is enclosed in a separate bag. See procedure under item 1...5
on the right. Insert an O-ring in the sensor hole using the mounting
pin supplied.
If the sensor is installed in a pocket, it must be inserted as far as the
bottom of the pocket and then secured. The pockets are best installed
in T-pieces with a 45° or 90° angle. The tip of the pocket must point in
the opposite direction to the direction of flow and must be located
in the middle of the pipe.
The temperature sensors must be sealed after installation in the
pockets.
The operation of any violation of this guidance will result in
immediate invalidation of the factory warranty and verification.
Connect the sensor cables to terminals as shown below.
- For 2-wire connection to terminal 5-6 and 7-8
- For 4-wire connection to terminal 1/5 - 6/2 and 3/7 - 8/4
