Read these Safety Instructions before using the switch for the first time and follow the Operating instructions.
Safety instructions
1. The installation, initial operation and maintenance should only be carried out by a qualified expert with electrical know-how.
2. Comply with the local and statutory rules and/or the VDE0100.
3. Before electrical connection, check the specifications on the data plate and the technical data of this manual.
4. A fuse must be connected in series to the supply voltage, according to the Standard and Normative documents.
5. Protect the signal contacts of the limit switch against voltage peaks when inductive or capacitive loads are connected.
6. The device may be put into operation only if the electrical connection is correct. To secure the type of protection, the sealing cap and the gasket
must be placed correctly.
7. The earth connection of the device has to be installed in such a way that mechanical damage will be excluded.
8. For a proper function, the paddle must not touch the pipe
9. For a proper function, the device must be installed in straigh pipes with a mininum length at least of five times the diameter and far from valves or
filters to avoid turbulence.
10. Switch off the power supply, before disconnecting the device.

2. Installation
-
-
The switch has to be insterted between a pipe welding the device
or using proccess accesories depending on the model.
The models LIT-2 and LIT-VT can be side or vertically mounted due
to a return spring meanwhile the others has to be inserted vertically.
The indication arrow in the body has to be faced to the flow.
- Fasten the DIN connector after making the electrical connection.
- Fix and fasten the screw of the DIN connector to ensure the
water-tightness.
2.1 Preparing for use
For a proper function, the device must be installed in straigh pipes
with a mininum length at least of five times the diameter and far
from valves or filters to avoid turbulence.
Read the Safety Instructions and the Operation Instructions before
using the controller.

Sensitivity adjustment
- The flow switches LIT-VL/VP/VT switch with a fix flow of 1 l/min.
- The flow switche LIT-VTM switchs with a fix flow of 0.5 l/min.
- The flow switch LIT-2 has a regulation system that allows the
adjustment of the sensitivity. Open the cap in the back of the
device body and turn the screw to reduce the sensitivity and
increase the strain of the flow to activate the microswitch.
Unterclockwise insensitive. The device is adjusted at the
maximum sensitivity.
- The range of flow can be consulted in the following table
(LIT2LITV-008)
* Tolerance ± 15% scale range.
Minimum hysteresy 0.7 l/min.
