LM3 Installation, Operation Manual
Assembly
-
Check the o-rings (5, 6) and exchange damaged o-rings if necessary.
-
Lubricate the radial o-rings (5) with Vaseline or o-ring grease.
-
Remove any grease residue from the axial-o-ring (6).
-
Plug the cable section (3) straight into the plug of the sensor section (2).
-
Hold the probe onto the sensor section (2) with one hand. Screw on and tighten the
nut (4) carefully with the other hand. Prevent torsion of the cable section (3) against the
housing!
Accuracy 0.1% FSO
Devices with an accuracy of 0.1 % FSO have micro-controlled electronics for processing and improving the signal.
As a matter of principle, the processing takes more time than for analogue sensors, which have only an amplifier.
Due to this longer response time, the output signal follows the measured value discontinuously. For relatively stable
measuring values, this characteristic is secondary. Please compare the specification for the response time in the
data sheet.
Initial start-up
Y
WARNING!
Before start-up, the user has to check for proper installation and for any visible defects.
Y
WARNING!
The device can be started and operated by authorized personnel only, who have read and
understood the operating manual!
Y
WARNING!
The device has to be used within the technical specifications, only (compare the data in the data
sheet)!
Placing out of service
Y
WARNING!
When dismantling the device, it must always be done in the depressurized and currentless
condition! Check also if the medium has to be drained off before dismantling!
Y
WARNING!
Depending on the medium, it may cause danger for the user. Comply therefore with adequate
precautions for purification.
Maintenance
In principle, this device is maintenance-free. If desired, the housing of the device can be cleaned when switched off
using a damp cloth and non-aggressive cleaning solutions.
Depending on the measuring medium, however, the diaphragm may be polluted or coated with deposit. If the
medium is known for such tendencies, the user has to set appropriate cleaning intervals. After placing the device
out of service correctly, the diaphragm can usually be cleaned carefully with a non-aggressive cleaning solution and
a soft brush or sponge. If the diaphragm is calcified, it is recommended to send the device to Winters Instruments
for decalcification. Please read therefore the chapter “Service / Repair” below.
!
An incorrect cleaning can cause irreparable damages on the diaphragm. Never use spiky objects or pressured
air for cleaning the diaphragm.
