Temperature sensors
Note: The temperature sensor type PT 100 / 500 must correspond
to the information on the dial plate.
Note: If detachable temperature sensors are used they must have
their own calibration or certification of conformity!
Note: The maximum cable length of the temperature sensors is
10 m. Extension is not permitted.

Connect the cores in line with the inscription printed on the meter.
The 2-wire connection occurs on terminal 5/6 and 7/8.
This also applies to a connection of 2-wire temperature sensors on a 4-wire
connection terminal.
Note: Do not connect the shielding braid on the calculator side.
•
Insert the temperature sensors into the pockets, ball-valves or T-pieces.
The end of the temperature sensors must reach at least to the centre of the
pipe cross-section.
•
Seal the temperature sensors to protect against manipulation.
•
Put the housing cover in position and press it gently until all the lugs click
into place audibly.
