The product family of Liquiphant M FTL5x

The Liquiphant M is a level limit switch for applications in all kind of liquids. Small process connections and dimensions allow an

operation in pipes with diameters as small as DN50.

Liquiphant M is also available in compact housing design. This version can not be repaired because it is filled with Silgel and welded.

It is not specified in this Service Manual.

Operation principle of the Liquiphant M/S

The sensor, shaped like a tuning fork, is excited in its resonance frequency (oscillation circuitry) by means of a piezo driver. An

immersion into a liquid medium causes the resonance frequency to decrease. This frequency change is evaluated in the CPU and

transmitted to the output stage as a binary signal via an opto-coupler (galvanical separation). An external load like a relay, PLC or

separate switching device can then generate a safety reaction.

The limit switch can be set to either minimum or maximum failsafe mode, depending on the application. In case of a power fail, the

electronic switch will be "open" or a relay will be de-energized.

The electronics of Liquiphant M/S

Nine electronics are available for Liquiphant M and Liquiphant S. They are used depending on the application and safety requirements

(certificates).

• FEL51: 2-wire AC connection 19...253 V AC

• FEL52: 3-wire DC connection 10...55 V DC

• FEL54: Universal current connection 19...253 V AC or 19...55 V DC with relay output

• FEL55: 2-wire connection for separate switching unit e.g. PLC

• FEL56: 2-wire connection for separate switch amplifier according to NAMUR (L-H edge)

• FEL58: 2-wire connection for separate switch amplifier according to NAMUR (H-L edge)

• FEL57: 2-wire connection, PFM signal for separate switching unit Nivotester

• FEL50A: 2-wire connection for power supply and data transfer, connection to PROFIBUS PA

• FEL50D: 2-wire connection for connecting to the density and concentration computer FML621.

ATTENTION: This electronic insert cannot be installed in devices that were originally used as a limit switch.

Electronic inserts FEL5x, connection data

The illustrations show the functional wiring in an installation. Hints regarding the applicable national or international installation

guidelines for explosion hazardous areas must be observed. It is mandatory to take into account the grounding concept used by the

customer.

Connection data (load) FEL51

• Relays with a minimum holding power/rated power >2.5 VA at

253 V AC (10 mA) or >0.5 VA at 24 V AC (20 mA)

• Relays with a lower holding power/rated power can be operated by

means of an RC module connected inparallel.

For example: Fischer & Tausche Type 9725 A, 0.5 μm 220 Ω, 250 V~,

HPF565 P1

• Relays with a maximum holding power/rated power <89 VA at

253 V AC or <8.4 VA at 24 V AC

• Voltage drop across FEL51 max. 12 V

• Residual current with blocked thyristor max. 3,8 mA

• Max. load current 375 VA at 253 V or max. 36 VA at 24 V (not short-circuit proof)

The external load must not be to small. Due to the residual current (max.

3.8 mA) required for the operation of the electronics, a relay with a low

energizing current would be correctly energized but not properly return to

the non-energized failsafe position. In such cases, an additional shunt

resistor can be used to reduce the relay current.

Example: A shunt resistor of 39 k Ω / 2W is recommended for an OMRON

relay type MY4/220V.

Test circuit dor PFM devices

ATTENTION: This measurement may not be performed in an Ex area!

The test circuit only applies to Liquiphant M with electronic insert FEL57.

This electronic insert converts the signal from the tuning fork into a pulse frequency modulation (PFM). The output signal jumps from

a high to a low PFM frequency when the sensor is covered. The PFM signal can only be processed by the listed E+H Nivotesters.

• current pulses of approximately 11 mA are superimposed to the supply current, as shown on the oscillogram

• in order to measure the signal current, a test resistor of approximately 10 Ohms must be inserted into the negative line between

the FEL57 and the Nivotester FTL...

• an oscilloscope must be connected parallel to the resistor

• for the test, the fork oscillates freely or is manually dampened

• the Nivotester FTL325P/375P must then change it switching status

The PFM signals must then appear as shown, adjustments cannot be made.

Disassembly of Liquiphant M/S

The Liquiphant M family consists of 5 different instrument types: FTL50/51, FTL51C and FTL50H/51H. The family contains a

compact design (FTL50), a version with extension pipe (FTL51), a coated sensor (FTL51C) as well as a polished fork for the use in

hygienic applications (FTL50H/51H).

The Liquiphant S family covers two different instrument types - the compact design of FTL70 and the version with extension pipe

FTL71.

Each instrument type of Liquiphant M and Liquiphant S can be combined with various housings, electronics and process connections.

The mounting of the electronic insert and the sensor is identical for all instruments. For instruments with housing T13/F13, the

sensor and the housing are screwed together.

The electronic exchange at Liquiphant M with housing T13 (EEx de) is described separately.

Disassembly

1 Unscrew lid. If available, loosen cover lock.

2 Disconnect cables.

3 Loosen two mounting screws and pull out electronic insert.

4 Loosen screw from mounting adapter (for stainless steel housing

F15 only).

5 Loosen external circlip from sensor head using circlip pliers.

Then remove mounting parts.

6 Disconnect ground cable from external circlip.

7 Separate sensor from housing (also at extended version)

• for devices with housing F15/16/17, the sensor must be

pulled down out of the housing.

• for devices with housing F13, the sensor must be screwed out of the housing (12 turns).

Diagnostics at Liquiphant M/S

Each electronics features "diagnostics outputs" providing measuring signals for control purpose. These include the sensor oscillation

signal, the switching signal and the identifier of the electronics version. Using small probes (i. e. wire < 1 mm Ø), the signal frequency

and amplitude can be monitores on an oscilloscope.

Identification resistor

FEL51 = 1k000

FEL52 = 1k540

FEL54 = 2k260

FEL55 = 3k320

FEL56 = 4k870

FEL57 = 6k810

FEL58 = 8k210

FEL50A = 10k000

Switching signal without delay

Opposed to the switching output at the terminal block,

which is always delayed by 0.5 seconds, this signal istaken directly from the processor.

Advantage: eventual erroneous switching caused by

external vibration can be detected with an oscilloscope.

fork free = 0 V

fork covered = approx. 4.8 V

Sensor signal

• The sensor signal has an offset of approx. 4 V DC.

• The amplitude is approx. 2 Vss. The signal is in

saturation, therefore not a sine wave.

• The frequency of the fork is:

- not covered / in air approx. 900...1200 Hz- covered to switch point approx. 850 Hz

(10...15% below resonance frequency)

• The frequency depends on the insertion depth, the

amplitude on the viscosity.

ATTENTION!

With the sensor removed from the instrument, the"Signal In" and "Signal Out" can be checkedagainst ground with an oscilloscope connected tothe socket.

The sensor is momentarily excited by carefully tapping the fork. If the piezo and the connecting flexible conductor strip are in order, a dampenedsine wave can be measured at the respective test points.

This test is only a function test, it does not allow astatement about the quality of the sensor. A check of the data stored in the EEPROM or an exchangeof the EEPROM is not possible.
