Safety instructions LUC-M**
1 Safety instructions
1.1 Designated use
The LUC-M** is a compact measuring device for continuous, non-contact level
measurement. Depending on the sensor, the measuring range is up to 15 m in
fluids and up to 7 m in bulk solids. By using the linearisation function, the LUC-M**
can also be used for flow measurements in open channels and measuring weirs.
1.2 Installation, commissioning, operation
The LUC-M** is fail-safe and is constructed to the state-of-the-art. It meets the
appropriate standards and EC directives. However, if you use it improperly or other
than for its designated use, it may pose application-specific hazards, e. g. product
overflow due to incorrect installation or configuration. Installation, electrical
connection, start-up, operation and maintenance of the measuring device must
therefore be carried out exclusively by trained specialists authorised by the system
operator. Technical personnel must have read and understood these operating
instructions and must adhere to them. You may only undertake modifications or
repair work to the device when it is expressly permitted by the operating
instructions.
1.3 Hazardous area
Measuring systems for use in hazardous environments are accompanied by
separate "Ex documentation", which is an integral part of this Operating Manual.
Strict compliance with the installation instructions and ratings as stated in this
supplementary documentation is mandatory.
• Ensure that all personnel are suitably qualified.
• Observe the specifications in the certificate as well as national and local
regulations.

3.3 Installation conditions
3.3.1 Installation conditions for level measurements
• Do not install the sensor in the middle of the tank (3). We recommend leaving a
distance between the sensor and the tank wall (1) measuring 1/6 of the tank
diameter.
• Use a protective cover, in order to protect the device from direct sun or rain (2).
• Avoid measurements through the filling curtain (4).
• Make sure that equipment (5) such as limit switches, temperature sensors, etc.
arenotlocatedwithintheemittingangleα.Inparticular,symmetricalequipment
(6) such as heating coils, baffles etc. can influence measurement.
• Align the sensor so that it is vertical to the product surface (7).
• Never install two ultrasonic measuring devices in a tank, as the two signals may
affect each other.
• To estimate the transmitted echo beam and its detection range, use the 3 dB
emitting angle α:

3.3.2 Installation in narrow shafts
3.3.3 Installation conditions for flow measurements
• Install the LUC-M** at the inflow side, as close above the maximum water level
Hmax as possible, plus the blocking distance BD.
• Position the LUC-M** in the middle of the channel or weir.
• Align the sensor membrane parallel to the water surface.
• Keep to the installation distance of the channel or weir.
• You can enter the "flow to level" linearisation curve ("Q/h curve") using via the
on-site display.
Example: Khafagi-Venturi flume
In narrow shafts with strong interference
echoes, we recommend using an
ultrasound guide pipe (e. g. PE or PVC
wastewater pipe) with a minimum
diameter of 100 mm.
Make sure that the pipe is not soiled by
accumulated dirt. If necessary, clean the
pipe at regular intervals.

3.4 Measuring range
3.4.1 Blocking distance, nozzle mounting
Install the LUC-M** at a height so that the blocking distance BD is not undershot,
even at maximum fill level. Use a pipe nozzle if you cannot maintain the blocking
distance in any other way. The interior of the nozzle must be smooth and may not
contain any edges or welded joints. In particular, there should be no burr on the
inside of the tank side nozzle end. Note the specified limits for nozzle diameter and
length. To minimise disturbing factors, we recommend an angled socket edge
(ideally 45°).
BD: blocking distance; SD: safety distance; E: empty calibration; F: full calibration
(span); D: nozzle diameter; L: nozzle length
"Caution!
If the blocking distance is undershot, it may cause device malfunction.
!Note!
In order to prevent the level from entering the blocking distance, you can specify a
safety distance (SD). If the level is within this safety distance, the LUC-M** outputs
a warning or alarm message.

Installation LUC-M**
3.4.2 Safety distance
If the level rises to the safety distance SD, the device switches to warning or alarm
status.
The size of SD can be set freely in the "Safety distance" (015) function. The
"in safety distance" (016) function defines how the device reacts if the level enters
the safety distance.
There are three options:
•Warning: The device outputs an error message but continues measurement.
•Alarm: The device outputs an error message. The output signal assumes the
valuedefinedinthe"Outputon alarm" (011)function(MAX,MIN,user-specific
value or holds the last value). As soon as the level drops below the safety
distance, the device recommences measurement.
•Self holding: The device reacts in the same way as foran alarm. However, the
alarm condition continues after the level drops below the safety distance. The
device only recommences measurement when you cancel the alarm using the
"Ackn. alarm" (017) function.
3.4.3 Range
The sensor range is dependent on the measuring conditions. Refer to Technical
Information TI 365O/98/en for an estimation. The maximum range is shown in the
above diagram (valid for good conditions).
