Note
The extra opening in the bottle adapter is used for ventilating the con-
tainer. This opening may not be sealed. The pressure equilibrium in the
container must always be ensured.
A 6.1619.000 adsorber tube can be attached with the bottle adapter
for the 6.1113.100 and 6.1113.110 sensors. This adsorber tube (with M6
thread) can be filled with a suitable material which protects the contents
of the container, e.g. against CO
2
or humidity.
Overflow monitoring
In the case of overflow monitoring, connect the black plug of the sensor
cable to the connector F (Level Full). The Full level connector must be
linked with a short sensor rod (activation upon contact).
Empty level monitoring
In the case of empty level monitoring, connect the black plug of the sen-
sor cable to the connector E (Level Empty). The Empty level connector
must be linked with a long sensor rod (activation when contact is lost).
A second sensor cable will be required in the event that Level full and
Level empty monitoring are to be performed simultaneously. It is sufficient
to plug the black plug of the second cable into the corresponding connec-
tor E or F. No second reference connection is required.
