connector into the sensor’s
three notches (crimps) and
press them together.
■
Use the mounting aid as position-
ing aid.
■
Mounting with brass adaptor:
– Slide brass screwing with
loosely mounted groove pin
onto temperature sensor in right
position
– Slide temperature sensor into
mounting aid until mechanical
stop (28 mm)
– Check again, if brass screwing is
in right position (the groove pin
must be pressed in the upper
groove which is in the closest
position to the temperature
sensor cable)
– Press in groove pin ush
– Remove mounting aid
■
Insert the temperature sensor
into the installation point and
screw it in tightly until the dead
stop of the seal on the 12-point is
reached (mounting torque
3-5 Nm).
■
The temperature sensor instal-
lation point which is optionally
integrated in the ow sensor must
be secured.
■
Secure the sensor aer instal-
lation against unauthorised
removal with appropriate sealing
(included in accessories kit)!
■
At the versions with temperature
sensor type TS-45-5 (see type
plate at the sensor cable) both
sensors must be always immersed
directly in contact with the heat
conducting uid. The installation
in sensor pockets is not allowed.
Installation with existing immersion
sleeves
In Germany the C5 can be put into
use in connection with existing im-
mersion sleeves in accordance with
the article “Putting into use of MID
homologated temperature sensors”
released in the PTB notications 119
(2009), Edition 4. Based on current
information, the regulation has a pe-
riod of validity until 30.10.2026. For
the identication and marking of the
usable existing immersion sleeves
in connection with the C5 meter, an
identication and marking set can be
delivered from our company (order
number 137382).
Commissioning

■
If the sleep mode of the counter is
enabled (Display: SLEEP 1), then
it must be deactivated by longer
pressing the button (>5s).
■
While the system is operating,
check whether the volume display
advances and the temperatures
displayed correspond with the ac-
tual temperatures (see the display
overview).
■
Wait for the temperature display
to be updated.
■
Secure meter with the enclosed
sealing material against unau-
thorised removal.
