Tecma.
Tecma sensors can be of two types:
- Pressure switch
- Field-effect (Mirus cel)
For the installation guide see Appendix A3
Pressure switch
The pressure switch sensors can run with any panel. They are connected to the control unit
with the grey/black wire (two-level version: red / black and white / green). In the presence of
several control units on board, you must wire all the control units together before connecting
the sensor. See fig. as example.
Field-Effect
These sensors can run with any panel. They can be attached outside of the blackwater tanks
(max thickness of 10 mm).

Full Tank Sensor
•
Mid Tank Sensor
–
Optional
Use isopropyl alcohol (not included) to clean the side of the tank at the top - approximately
on the left-right centreline where the sensor will be mounted. When thoroughly clean and
dry, firmly press the sensor into place.
(Note: Wires can face any direction. The direction of the sensors does not affect its
operation).
If available,
follow the same procedure for the Mid-Tank sensor. However, keep in mind that
it should be assembled on the left-right centreline, approximately half way up the side of the
tank.
The Full Tank Sensor
has to attached at the highest point on the tank for the tank’s capacity,
or where the installer wants the Tank Full level to be.
The sensor has a removable cover over the pressure-sensitive adhesive pad.
