3.8.1 Aligning the housing

The housing can be rotated 270° to align the cable entry.
For an even better way of preventing moisture penetration, we recommend you route the
connecting cable downwards before the cable gland and secure it with a cable tie. This is
particularly recommended when mounting outdoors.
Housing (type F16, F15, F17, F13, T13)

• Unscrew cover
• Loosen Phillips screw at bottom of housing by turning the screw 3 to 4 times
• Turn the housing to the desired position (max. 270°, from one stop to the next)
• Tighten Phillips screw at bottom of housing.

2. Align the housing.
3. Tighten clamping screw (< 1 Nm) until the housing can no longer be rotated.
4. Additional protection against moisture penetration for electronics compartment.
3.8.2 Sealing the probe housing

No water should enter the device when performing installation, connection and
configuration tasks. Always seal the housing cover and cable entries securely.
The O-ring seal on the housing cover is shipped with a coat of special lubricant applied. In
this way, the cover can be sealed tight and the aluminum thread does not bite when screwing
down.
Never use mineral oil-based grease as this destroys the O-ring.
3.9 Post-installation check

After installing the measuring device, carry out the following checks:
• Is the device damaged (visual inspection)?
• Does the device meet the specifications at the measuring point with regard to process
temperature/pressure, ambient temperature, measuring range etc.?
• Has the process connection been tightened with the appropriate tightening torque?
• Are the measuring point number and labeling correct (visual inspection)?
• Is the device adequately protected against precipitation and direct sunshine?
3.9.1 Measuring range with FEI50H (HART)

• Measuring frequency: 500 kHz
• Span: C = 25 to 4000 pF recommended (2 to 4000 pF possible)
• Final capacitance: CE = max. 4000 pF

" Caution!
Before connecting the supply voltage, note the following:
• The supply voltage must match the data specified on the nameplate (1).
• Switch off the supply voltage before connecting the device.
• Connect the potential equalization to the ground terminal on the sensor.
! Note!
• When using the probe in hazardous areas, the relevant national standards and the
information in the safety instructions (XA) must be observed.
• Use the specified cable gland only.
4.1 Recommendations for connection
4.1.1 Potential equalization
" Caution!
In Ex-applications, the screen may only be grounded on the sensor side.
Connect the potential equalization to the outer ground terminal of the housing (T13, F13,
F16, F17, F27). In the case of the stainless steel housing F15, the ground terminal
(depending on the version) can also be located in the housing.
For further safety instructions, please refer to the separate documentation for applications
in hazardous areas.
4.1.2 Electromagnetic compatibility (EMC)

Interference emission to EN 61326, Electrical Equipment Class B. Interference immunity to
EN 61326, Annex A (Industrial) and NAMUR Recommendation NE 21 (EMC).
4.1.3 Cable specification

The electronic inserts can be connected using commercially available instrument cables.
When using shielded instrument cables, it is recommended to connect the shielding on both
sides to optimize the shielding effect (if potential equalization is present).

! Note!
The device is operated via the electronic insert, the display or with FieldCare. If a display is
attached to the electronic insert, the function keys (- key/ + key) and the Mode switch at the
electronic insert are deactivated. All other settings can be made using the function keys on
the display or with FieldCare.
6.1 Installation and function check

Make sure that the post-installation check and final check have been completed before you
start your measuring point:
• See "Post-installation check" checklist  ä 21
• See "Post-connection check" checklist  ä 26
6.2 Basic setup without the display/operating module

This section describes how to commission the device with the function switch and the
operating keys (–/+) on the FEI50H electronic insert.
! Note!
• On leaving the factory, Liquicap M devices are calibrated for media with a conductivity of
 100 μS/cm (e.g. for all water-based liquids, acids, alkalis ...). A recalibration is only
necessary if the 0 %-value or the 100 %-value should be adjusted to suit customer-specific
requirements, the distance to the tank wall is < 250 mm or if the liquid is not conductive.
• Only the "Wet" type of calibration can be carried out without the display and operating
module.
During wet calibration ("Wet" operating mode), the 0 %-value and/or the 100 %-value is
adjusted to customer-specific requirements. This calibration can be carried out if the tank is
empty, full or partially full. During full calibration, the probe must be covered by liquid in the
installed state.
An empty and full calibration must be performed.

6.2.1 Function switch - position 1

Operation
In normal operation, the function switch must be set to position 1.

Measuring modes
! Note!
Before carrying out empty and full calibration, the medium properties must be configured. If
the medium is conductive and tends to form buildup, the "Buildup" operating mode must be
selected.
In this operating mode, the buildup on the probe rod is compensated.
The "No buildup" operating mode is set at the factory.
"Medium property" subfunction

The "No buildup" operating mode should be set for media that do not tend to form buildup
on the probe rod (e.g. water, beverages etc.). As of a conductivity of 100 μS/cm (i.e. all
water-based liquids, acids, alkalis ...), the measured value is independent of the conductivity
of the liquid (independent of concentration fluctuations).
In the "Buildup" operating mode, the buildup compensation function integrated in the
software is activated. In this operating mode, the measured value is independent of the
conductivity of the liquid as of a conductivity of 1000 μS/cm (independent of concentration
fluctuations).
This compensates measuring errors caused by conductive media sticking to the probe rod
(e.g. yoghurt). This corresponds to buildup compensation.
Proceed as follows to chose between media forming buildup (e.g. yoghurt) and media not
forming buildup (e.g. water):
• Turn the function switch to position 4
• "Buildup" operating mode
=> Press the + key for media that tend to form buildup.
=> The green LED confirms your entry by flashing three times.
• "No buildup" operating mode
=> Press the – key for media that do not form buildup.

Carry out empty calibration (for empty tanks)
If the tank is empty (0 %), the empty calibration sets the signal current to the lower value of
4 mA. When empty calibration is completed, the current value of 4 mA is displayed at the
ammeter.
Proceed as follows to perform empty calibration:

• Press the – and + keys together for approx. 2 s until the green LED flashes*
=> Release the two keys again.
=> The flashing stops after approx. 5 s.
=> Empty calibration is saved.
* SW version 1.00.00 flashes red.

Carry out empty calibration (for almost empty tanks)
If possible, the exact level of the tank should be known and should not be too large (< 30 %).
44 Endress+Hauser
Too high a level reduces the accuracy of the zero point (corresponds to the empty tank). An
ammeter must be connected to the current pick-off at the electronic insert.
Let us presume that the level was determined for 15 %. Now the current value that
corresponds to the level of 15 % must be determined. The lower current value can be
adjusted with the +/– keys. The + key increases the value, the – key reduces the value. The
following must also be considered:
1. The lower current value (= empty tank, 0 %) is 4 mA.
2. The upper current value (= full tank, 100 %) is 20 mA.
3. This results in a measuring range of 16 mA for a change from 0 % to 100 %,
i.e. 0.16 mA increase in the current for every 1 % increase in the level.
4. For a 15 % level, this is 15 % x 0.16 mA/% which equals 2.4 mA. This must be added to
the 4 mA to obtain the current value to be set: 2.4 mA + 4 mA = 6.4 mA.
Proceed as follows to perform empty calibration on a partially filled tank:

• The current value can be adjusted with the +/– keys. For this purpose, press the + or – key
for at least 2 seconds. You can set the desired current value (> 4 mA) using the mulitmeter
connected.
• The empty calibration is saved when you release the key.

Carry out full calibration (for full tanks)
If the tank is full (100 %), the full calibration sets the signal current to the upper value of 20
mA. When empty calibration is completed, the current value of 20 mA is displayed at the
ammeter.
Proceed as follows to perform full calibration:

• Press the – and + keys together for approx. 2 s until the green LED flashes*
=> Release the two keys again.
=> The flashing stops after approx. 10 s.
=> Full calibration is saved.
* SW version 1.00.00 flashes red.

Carry out full calibration (for almost full tanks)
If possible, the exact level of the tank should be known and should be as large as possible (>
70 %).
Too low a level reduces the accuracy of the upper point (corresponds to the full tank). An
ammeter must be connected to the current pick-off at the electronic insert.
Let us presume that the level was determined for 90 %. Now the current value that
corresponds to the level of 90 % must be determined. The upper current value can be
adjusted with the +/– keys. The + key increases the value, the – key reduces the value.
The following must also be considered:

1. The lower current value (= empty tank, 0 %) is 4 mA.
2. The upper current value (= full tank, 100 %) is 20 mA.
3. This results in a measuring range of 16 mA for a change from 0 % to 100 %,
i.e. 0.16 mA increase in the current for every 1 % increase in the level.
Endress+Hauser 45
4. For a 90 % level, this is 90 % x 0.16 mA/% which equals 14.4 mA. This must be added
to the
4 mA to obtain the current value to be set: 14.4 mA + 4 mA = 18.4 mA. (You can also
take
the upper current value and then subtract 10 % x 0.16 mA/% = 1.6 mA from 20 mA.)
Proceed as follows to perform full calibration on a partially filled tank:

• The current value can be adjusted with the +/– keys. For this purpose, press the + or – key
for at least 2 seconds. You can set the desired current value (< 20 mA) using the
mulitmeter connected.
• The full calibration is saved when you release the key.

Measuring range
At the factory, the measuring range is always calibrated to the probe length ordered. If the
electronic insert is used in another probe, the measuring range must be configured in
accordance with the probe length.
Proceed as follows to configure the measuring range 2000 pF (probe length < 6 m) or 4000
pF (probe length > 6 m):
• Press the – key to set 2000 pF
• Press the + key to set 4000 pF

Proof test (self-test)
! Note!
• From version FW: V 01.03.00
• Before and after the automatic proof test, it is essential to check whether the level value
displayed corresponds to the actual level value.
When the self-test is activated, the current output is set to 4 mA and follows a ramp function
up to 22 mA. This test is completed after approx. 40 s.
Proceed as follows to activate the device self-test:

• Press the – and + keys together to start the function test
=> The green LED flashes quickly until the error current is reached. The red LED flashes
until the test is completed.
! Note!
After the self-test, the device automatically returns to the operating mode.

Reset - restore factory settings
" Caution!
The reset can affect the measurement as the current values are overwritten by those of the
factory calibration (0 % (4 mA) and 100 % (20 mA)).
Proceed as follows to restore the factory settings:
• Disconnect the electronic insert from the power supply
46 Endress+Hauser
• Press and hold the – and + keys together while the device is being reconnected to the
power supply
=> red LED flashes slowly and then starts to flash quickly
• The device reset is complete when the red LED goes out
• Release the – and + keys again

Download/Upload sensor DAT (EEPROM)
Calibration values can be transmitted with this function. A distinction is made between two
types:
• The sensor has been replaced and the electronic insert should continue to be used.
• The electronic insert has been replaced but the sensor should continue to be used.
For instances of this nature, the calibration values already set can be transferred from the
sensor to the electronic insert or from the electronic insert to the sensor.
Proceed as follows to transfer the calibration values from the electronic insert to the sensor:
Download
• Press the – key to start downloading from the electronic insert to the sensor
=> The green LED flashes for approx. 2 s, thereby confirming your entry.

necessary if the 0 %-value or the 100 %-value should be adjusted to suit customer-specific
requirements, the distance to the tank wall is < 250 mm or if the liquid is not conductive.
• A distinction is generally made between two types of calibration:
Wet calibration:
During wet calibration ("Wet" operating mode), the probe must be covered by liquid in the
installed state. This calibration can be carried out if the tank is empty, full or partially full.
Empty and full calibration must be performed.
• Dry calibration
During dry calibration, empty and full calibration can be carried out without the probe
being in contact with the liquid. The calibration values can be entered directly in units of
length (e.g. m, mm, ...) for example.

The "No buildup" operating mode should be set for media that do not tend to form buildup
on the probe rod (e.g. water, beverages etc.). As of a conductivity of 100 μS/cm (i.e. all
water-based liquids, acids, alkalis ...), the measured value is independent of the conductivity
of the liquid (independent of concentration fluctuations).
In the "Buildup" operating mode, the buildup compensation function integrated in the
software is activated. In this operating mode, the measured value is independent of the
conductivity of the liquid as of a conductivity of 1000 μS/cm (independent of concentration
fluctuations).
This compensates measuring errors caused by conductive media sticking to the probe rod
(e.g. yoghurt). This corresponds to buildup compensation.
"Cal. type" subfunction

In the "Dry" "Cal. type" empty and full calibration can be carried out without the probe being
in contact with the liquid. The calibration values can be entered directly in units of length
(e.g. m, mm, ...) for example.
In the "Wet" "Cal. Type", the probe must be covered by liquid in the installed state for full
calibration. This calibration can also be carried out if the tank is partially full. Both the empty
calibration and full calibration must be performed.

1.) e.g. water (the medium must be conductive  100 S/cm)

2.) emulsion
3.) e.g. oil ( nonconductive medium < 1 S/cm and DC < 5)
The program calculates the calibration values on the basis of the data entered (e.g. probe
length, probe type, medium properties etc.). The secure functioning of interface
measurement can already be determined at this time.
The calculated calibration values can be transmitted to the FEI50H electronic insert via the
display or Fieldcare.

"Empty calibration"
1. Fill the container with the top medium and perform "Empty calibration" 0 % (see basic
setup  ä 48)
If it is not possible to fill with medium, "Empty calibration" can also be performed with
the probe exposed (in the air). A calibration inaccuracy of approx. 2.5 % per meter
should be expected here (oil and water are the reference media).
"Full calibration"
2. Fill the container with the bottom medium and perform "Full calibration" 100 % (see
basic setup  ä 48)
You have now performed basic setup.

Maintenance Liquicap M FMI51, FMI52
7 Maintenance
No special maintenance work is required for the Liquicap M level transmitter.
External cleaning
When externally cleaning Liquicap M, make sure that the cleaning agent used does not
attack or corrode the housing surface or seals.
Cleaning the probe

Depending on the application, buildup (contamination and soiling) can form on the probe
rod. A high degree of material buildup can affect the measurement result. If the medium
tends to create a high degree of buildup, regular cleaning is recommended. When hosing
down or during mechanical cleaning, it is important to make sure that the insulation of the
probe rod is not damaged. If cleaning agents are used make sure the material is resistant to
them!
Seals
The process seals of the sensor should be replaced periodically, especially when using
molded seals (aseptic version)! The intervals between seal replacement depend on the
frequency of the cleaning cycles and on the fluid and cleaning temperature.
Repair
The Endress+Hauser repair concept is devised in such a way that the devices have a modular
design and repairs can be carried out by the customers.
Spare parts are grouped into handy kits with related replacement instructions. The "Spare
parts" section lists all the spare part kits, including the order numbers, which you can order
from Endress+Hauser for repairing Liquicap M. For further information on service and spare
parts, please contact Endress+Hauser Service.
Repairing Ex-certified devices

The following information also has to be taken into account when repairing Ex-certified
devices:
• Ex-certified devices may only be repaired by experienced, skilled staff or by
Endress+Hauser Service.
• Applicable standards, national Ex-area regulations as well as the Safety Instructions (XA)
and certificates must be observed.
• Only genuine spare parts from Endress+Hauser may be used.
• When ordering spare parts, please note the device designation on the nameplate. Parts
can only be replaced by the same parts.
• Repairs must be carried out in accordance with the instructions. Following a repair, the
individual testing specified for the device must be carried out.
• Certified devices can only be converted to other certified device versions by
Endress+Hauser Service.
• Every repair and conversion made to the device must be documented.
Replacement
After replacing a Liquicap M or the electronic insert, the calibration values must be
transferred to the replacement device.
• When the probe is replaced, the calibration values in the electronic insert can be
transferred to the sensor DAT (EEPROM) module via a manual download.
• When the electronic insert is replaced, the calibration values of the sensor DAT (EEPROM)
module can be transferred to the electronics via a manual upload.
This means that you can restart the device without having to carry out a new calibration.

When cleaning, make sure that the cleaning agent used does not attack or corrode the
housing surface or seals.
Probe:
Depending on the application, buildup (contamination and soiling) can form on the probe
rod. A high degree of material buildup can affect the measurement result. If the medium
tends to create a high degree of buildup, regular cleaning is recommended. When hosing
down or during mechanical cleaning, it is important to make sure that the insulation of the
probe rod is not damaged.
