Microsonic hps+25/DD/TC/E/G1 Instruction Manual

Product description
The hps+ sensor measures the level in a
vessel in up to 6 bar overpressure contact-
less. The G1 and G2 threaded pipe end
permits the mounting and sealing of the
sensor in a flange of the vessel. The pnp
switched outputs are set according to the
adjusted detect distances.
The surfaces of the ultrasonic tranducers
of the hps+ sensors are protected by a
PTFE film (Teflon film) and sealed with a
FFKM O-ring against the sensor housing.
Therefore the surface of the ultrasonic
transducer can be cleaned from cakings
or spots.
Instruction manual
All settings are done with two push-but-
hps+ Ultrasonic Sensors for appli-
tons and a three-digit LED- display
(TouchControl).

Important instructions for assembly and ap-
plication
All employee and plant safety-relevant
measures must be taken prior to assembly,
start-up or maintenance work (see operation
manual for the entire plant and the operator
instruction of the plant).
The sensors are not considered as safety
equipment and may not be used to ensure
human or machine safety!
The hps+ sensors indicate a blind zone, in
which the distance cannot be measured. The
operating range indicates the distance of the
sensor that can be applied in normal atmos-
pheric preassure with sufficient function re-
serve.

Assembly instructions
► Assemble the sensor at the installation lo-
cation.
► If necessary seal the sensor with the en-
closed Viton O-ring (34 x 2,5 mm or 60 x 4
mm) against the flange.
► Plug in the connector cable to the M 12
connector.

Operation
hps+ sensors work maintenance free. Small
amounts of dirt on the surface do not influ-
ence function. Thick layers of dirt and caked-
on dirt affect the sensor function and there-
fore must be removed.

Note
In operation in overpreassure it is reco-
mended to adjust the sensitivity of the
hps+ sensor: choose the parameter A14 in
the Add-on menu and set it to sensitivity
E2 for atmospheric preassure from 1 to 3
bar or to sensitivity E3 for atmospheric
preassure > 3 bar.
hps+ sensors have internal temperature
compensation. Because the sensors heat
up on their own, the temperature com-
pensation reaches its optimum working
point after approx. 30 minutes of opera-
tion.
During normal mode operation, a yellow
LED signals that the corresponding
switched output has connected.
During normal mode operation, the mea-
sured distance value is displayed on the
LED-indicator in mm (up to 999 mm) or
cm (from 100 cm). Scale switches auto-
matically and is indicated by a point on
top of the digits.
During Teach-in mode, the hysteresis
loops are set back to factory settings.
If no objects are placed within the detec-
tion zone the LED-indicator shows »- - -«.
If no push-buttons are pressed for 20 se-
conds during parameter setting mode the
made changes are stored and the sensor
returns to normal mode operation.
Show parameters
Tapping push-button T1 shortly during nor-
mal mode operation shows »PAr« on the
LED-display. Each time you tap push-button
T1 the actual settings of the analogue output
and the switched output are shown.
