In separators with an automatic closure device, the SEPARIX-C L Plus must
be installed at a height above the closure device appropriate to the dimen-
sions and operating conditions of the separator so that the system operator
still has enough time to take the necessary measures in the event of an
alarm.
The interface sensor is equipped with a non-detachable blue cable (7) (3 x 0.5 mm²)
(SEPARIX-C L Plus: 5 m long). This cable can be shortened or extended up to 250 m with the
use of a junction box (1) suitable for the environmental conditions concerned and an exten-
sion cable (2).
If used in a potentially explosive atmosphere, the extension cable must not
exceed the maximum permissible capacitance and inductance of the meas-
uring transducer (see section 4.5). To avoid disturbances or damage to the
sensor or measuring transducer, the selected junction box must offer suffi-
cient protection against the ingress of moisture or fluid in the environmental
and operating conditions in which it is used.
For connecting the sensor to the measuring transducer, please observe the
installation instructions for SEPARIX-Control CT in this or another user guide
for compatible FAFNIR measuring transducers.
The correct operation of the sensors is guaranteed only in conjunction
with a compatible and approved measuring transducer.
