Microsonic pms-15/CI/A1 Operating Instructions

Product Description
The pms sensor has a stainless steel
housing and is designed for applica-
tions with hygienic requirements.
The ultrasonic transducer surface of
the pms sensors is laminated with a
PTFE film (Teflon film). The transdu-
cer itself is sealed against the hous-
ing by a joint ring.
The pms sensor with a D12 adapter
shaft can be fitted in a mounting clip
which meets hygiene standards like the

The special housing design ensures
Ultrasonic sensor with one that any cleaning fluids are able to
analogue output run off completely, regardless of the
intstallation situation.

For sensor setting, the accessory
LinkControl adapter LCA-2 is recom-
mended in combination with Link-
Control software for Windows©. Al-
ternatively, the sensor can also be set
by Teach-in via pin 2.

Proper use
pms ultrasonic sensors are used for
non-contact detection of objects.
The sensor must be mounted in an
EHEDG-approved mounting
such as the sensor screw connection
BF-pms/A1 for a EHEDG-complaint
use.
Installation
Assemble the sensor and its hygie-
nic D12 sensor screw connection
BF-pms/A1 or an equivalent sensor
mounting clip at the installation

Pull sensor cable through the sen-
sor gland, connect it to the M8
component in sensor plug.
Push the sensor with its shaft into
the sensor screw connection BF-
pms/A1 and adjust (see figure 3-

Maintenance
microsonic sensors are maintenance-
free. For cleaning in areas with hygi-
enic requirements, access to the sen-
sor must be guaranteed from all
sides. Cleaning is permitted up to a
cleaning temperature of 85°C. Do
not use a high-pressure cleaner to
clean the sensor.

Notes
The sensors of the pms family
have a blind zone. Within this
zone a distance measurement is
not possible.
If several pms sensors are operated
in a small space, the minimum
mounting for parallel or opposite
arrangement of the sensors shown
in figure 2 must be maintained.
The pms sensors are equipped
with an internal temperature com-
pensation. Due to the sensors self
heating, the temperature compen-
sation reaches its optimum
working-point after approx. 45
seconds of operation.
The sensor can be reset to its fac-
tory setting (see »Further set-
tings«).
For Teach-in procedure when us-
ing the LinkControl adapter (op-
tional accessory) the additional
adapter 5G/M12-4G/M12/M8 is
needed.
If the sensor is cleaned wet during
operation, all surfaces must be in-
clined at least 3° from the hori-
zontal alignment so that the clea-
ning agents can run off completely
(see figure 3).

sensor screw connection BF-pms/A1,
all surfaces must be inclined at
least 3°.
■ The D12 adapter shaft of the pms
sensor has to stick out at least
6 mm from the screw connection
(see figure 5).
The sealing ring has to fill space
between D12 sensor shaft and cap
nut. Sealing ring should not to be
pressed out excessively from the
shaft gland.
