1.1 Application
The Silometer FMX 570 is designed for level measurement with a capacitance or hydrostatic pressure probe in safe or explosion hazardous areas. It possesses an intrinsically-safe sensor circuit conforming to EEx ia IIC and IIB. A list of certificated combinations is to be found in »Notes on Safety« preceding this chapter. A working system for level measurement comprises:
Silometer FMX 570 transmitter,
Capacitance, Multicap or Deltapilot S probe
Electronic insert
Silometer function The capacitance or pressure measured by the sensor is converted into a frequency
signal by the electronic insert located in its head. The Silometer FMX 570 supplies the power and receives a level-proportional frequency signal over a two-core cable. The signal is then processed to provide a level or volume measurement.
Fail-safe operation If a fault condition is detected, e.g. a break in sensor - transmitter cable, the analogue
signal switches to -10 % or +110 % level or holds the last measured value. In addition, the alarm relay de-energises.

1.2 Measuring principle
The Silometer FMX 570 measures level on the basis of the capacitance and hydrostatic measurement principles. In both cases the measured value is processed by the electronic insert and passed on as a frequency signal.
The probe and vessel form the two plates of a capacitor, the total capacitance of which can then be calculated from the formula:
C
tot
=C
1
+ 2πε
r
x L pF (1)
--------------------------------
ln (D/d)
whereby C
tot

C
1
= capacitance or feed through
ε
0
= dielectric constant of air
ε
r
= rel. dielectric constant of product D= diameter of vessel d= diameter of probe L= length of probe immersed in
product in meters
If the product conducts, the capacitance is determined by the thickness and properties of the insulating material surrounding the probe. Equation (1) applies, whereby the variable D is now the diameter of the probe with insulation. In this case the capacitance varies by approx. 300 pF/m.
Measurement is independent of dielectric constant and not affected by changes in this variable.
In an open vessel, the level is derived from the hydrostatic pressure exerted by a column of liquid on a probe placed at its foot. The pressure exerted is:
p
1
= ρ x g x h (2)
whereby p
1
= hydrostatic pressure
ρ = density of the liquid
g = acceleration due to gravity h = height of the liquid column.
Assuming a constant density, the level of the liquid can be calculated from the pressure measured by the Deltapilot.

Technical data.
Warning!
The Silometer FMX 570 transmitter must be installed outside explosion hazardous
areas.
2.1 Probes and sensors
Table 2.1 lists the probes most frequently used with the Silometer FMX 570 transmitter. In addition to those listed, all probes which can be used with an EC 37 Z or EC 47 Z electronic insert can be connected to the transmitter. Installation hints can be taken from the appropriate Technical Information Sheet.
Sensor constants Deltapilot S sensors and EC 37 Z/47 Z inserts for capacitance probes are supplied with
the sensor constants zero frequency »fo« and sensitivity »f« or »S«. For Deltapilot S sensors the constants are printed on a label stuck inside the sensor head, for inserts they are printed on the name plate, see Fig. 7.1, Section 7.3.
Note these constants and enter them into fields V3H5 and V3H6 during commissioning, Section 4.1. This dispenses with the need for a recalibration of the transmitter on replacement of the sensor or insert.

2.4 Sensor connection
The Silometer FMX 570 can be operated with a variety of sensor types, each requiring a different electronic insert, e.g.:
EC 37 Z or EC 47 Z for capacitance and Multicap probes
EB 17 Z or EB 27 Z for Deltapilots
Sensor cableUse commercial 2-core installation cable, max. line resistance 25 /core, for the sensor/
transmitter cable. If electromagnetic interference is to be expected, we recommend
that the PFM negative line be grounded at the sensor (check Ex-regulations)
in case of heavy interference, that shielded cable be used, grounded at both
ends.
EC 37 Z and EC 47 ZThe electronic inserts EC 37 Z and EC 47 Z have two measuring ranges which can be
selected by inserting a bridge between terminals 4 and 5 of the insert, see Fig 2.6. Full instructions on the selection of the insert are to be found in Publication E 07.80.06/1c.

This chapter is concerned with the basic settings of the Silometer FMX 570 which allow it to operate for continuous level measurement. The principle sections describe:
Commissioning
Calibration for level measurement
Calibration for linear volume or weight measurement
Dry calibration for Deltapilot probes
Level offset
Display of measured values
Locking the parameter matrix.
The linearization for volume or weight measurements is described in Chapter 5, the setting of the analogue outputs in Chapter 6 and the controls in Chapter 3.
Note your settings!When configuring, note your parameters in the Table in the rear cover.
If the transmitter is ever replaced, these parameters can be entered at the
front panel. The transmitter will then measure correctly without the need for another calibration.
4.1 Commissioning
If programming the module for the first time, reset the module to the factory based
parameters, see Table in back cover. Then enter the probe constants fo and S (f). This
ensures that the EC 37 Z/EC 47 Z electronic insert or Deltapilot can be replaced without the need for recalibration, see Section 7.3.

5 V3H6 e.g. 0.652 Enter sensitivity, S or ∆f, of electronic insert or sensor 6 - »E« Register change
Operating modeThe operating mode is set at V8H0. Since the default value corresponds to level
measurement, this step can be omitted if the transmitter has been reset.
For a recalibration without reset check that mode 1, is on display:
1 = continuous level measurement, Sections 4.2, 4.3, 4.4.

4.2 Calibration for level measurement
This calibration requires the determination of two parameters,
an »empty« level at V0H1,
a »full« level at V0H2.
After calibration If the level is entered in %, after the calibration:
% level is displayed at V0H0
the 0/4…20 mA signal range corresponds to 0…100% level
the parameters »offset« and »sensitivity« are calculated and stored at
V3H1/V3H2.
If the level is entered in m, ft. etc. the analogue outputs must be set in the same units, see Chapter 6.

Note!
The calibration can be performed in reverse order
For bulk solids, the probe measures the depth of emersion in the product only.
Account for any filling mound or outflow depression by the entered levels.
For the Deltapilot S (liquids only), a »dry calibration« can be made see Section 4.4.
If appropriate, a linearization can now be carried out, see Chapter 5.

4.3 Calibration for linear volume or weight measurement
The Silometer FMX 570 can also be calibrated in volume or weight units, e.g. in litres, hectolitres, gallons, %vol, tonnes or kg. After calibration volume (or weight) is displayed at V0H0. The analogue output must be set in the same units, as described in Chapter 6.
If the level/volume relationship is not linear, i.e. the tank is a horizontal cylinder or has a conical outlet, the volume calibration is performed as part of the linearization procedure. In this case, before proceding further, turn to Chapter 5, Section 5.1 or 5.2 to determine the correct order of parameter entry.

4.4 »Dry calibration« for open vessels (Deltapilot)
It may not always be possible to fill and empty the vessel for the calibrations as described in Sections 4.2 and 4.3. To cover this eventuality the Silometer FMX 570 can be calibrated »dry« by using the sensor constants. For this alternative calibration you need:
the »zero frequency« and »sensitivity« of the sensors,
the »empty« level or offset at which the measurement should start
the maximum height of the liquid column and
the density of the liquid.
Caution!
Check the calibration during the first filling of the tank! If your calculations are
incorrect the levels measured will be incorrect also!

The sensor constants »f

« and »f«, see Section 2.1, are to be found in Table 2.2 on
page 9. For the theoretical calibration, however, it is recommended that the zero frequency of the installed Deltapilot S at atmospheric pressure is read from V0H8.

Note!
The zero frequency of the sensor is in fact dependent upon the sensor orientation,
so that there may be a slight difference between the value read from Table 2.2 and that of the factory calibration which is printed in the sensor housing. This effect is compensated during the standard calibration, where the factory values are used.

Offset and sensitivity of the display, V3H1/V3H2
The entry of values in V3H5/V3H6 adapts the Silometer to the application. It now knows which pressure is associated with a particular frequency. The next step is to adapt the display, i.e. the measuring range is fixed. This requires the entry of:
the offset in
mbar
in V3H1 The offset is the pressure in mbar which acts on the sensor when the display reads »0«, i.e.
V3H1 = p
zero
the sensitivity in
mbar/digit
in V3H2
The sensitivity determines the change
in the measured value h in V0H0 per
mbar change at the sensor, i.e.
V3H2 = p/h = (p

Sensitivity = p/h
= (980.7 - 44.13)/(100 - 0) = 936.6/100 = 9.366 mbar/%
Offset, V3H1 = 44.13 mbar
Sensitivity, V3H2 = 9.366 mbar/%

4.5 Level offset value
The calibration determines the level displayed at V0H0 for a particular head of liquid. By entering a level offset at V3H4 the displayed value can be corrected by the value entered.
The offset is
subtracted
from the true measured value
It must be entered in the units you have used for calibration
The analog output settings must be changed to follow the corrected
measurement.
For example, the Silometer FMX has been calibrated to display 0.0 at the level shown in Fig. 4.5. Sometime later it is decided that the true volume measured from the bottom of the tank is to be measured, i.e. when the liquid reaches the calibrated zero level, the display must indicate say 250 m

. The value -250 is entered:

the units used for calibration
2 - »E« Register entry

The corrected value is displayed (+250 instead of 0 at 0)
Note!
The offset can also be used if a linearization has been performed. In this case, the
offset is first subtracted from the »level« displayed at V0H9 and the result converted to the volume to be displayed at V0H0.

4.6 Measured value display
During normal operation the measured value can be read at V0H0 In addition to this, several other fields contain system information which might be needed, e.g., for trouble-shooting. Table 4.1 summarizes the measured value displays.
4.7 Locking the parameter matrix
When all parameter entries have been made (see also Chapters 56) the matrix can be
locked by entering a code number.

In this mode, all entries can be displayed but not changed.
The lock is released when a number between 670 and 679, e.g. 672, is
entered into the matrix at the same position.

5 Linearization
For tanks in which volume is not directly proportional to level, e.g. for horizontal cylinders or tanks with conical outlets, the linearization converts the level measurement into a measurement of capacity.
Parameters for linearization are selected and entered at fields V2H0V2H8. In addition,
the field V3H0 determines whether the associated calibration is to be performed in level
or volume units (0 = level default, 1 = volume). The following linearization modes can
be entered at V2H0:
0 = linear, default value 1 = horizontal cylinder 3 = manual entry 4 = cancel current setting
The modes horizontal cylinder and manual entry for conical outlets are described in Sections 5.1 and 5.2, all others in Section 5.3.
Two important rules must be observed when performing a linearization:
All level (or volume) entries must be made in the units you have chosen for
calibration at V0H1 and V0H2.
The levels for linearization and calibration must be referenced to the same
datum point.
After linearization After linearization:
The volume of liquid currently in the tank can be read from V0H0.
The level before linearization can be read from V0H9.
The 0/420 mA signal range must be set in the volume units entered,
see Chapter 6.

Note!
For capacitance or Multicap probes a ground tube is necessary or the liquid must
be conducting.
If a level calibration is made, V3H0 = 0, the calibration can preceed the linearization.
If the calibration is to be in
volume units
(V3H0 = 1),
the sequence of steps must be
exactly as shown above.
When V3H0 = 1, the entry at V2H7 fixes the end value for the level display at V0H9.

5.2 Linearization for a tank with conical outlet
Manual entry V2H0 = 3
This option allows you to enter your own characteristic, whereby two possibilities exist for entering the level values:
By hand: in this case both level and volume/weight parameters should be
calculated and entered in a table prior to configuration. A level calibration can always be performed.
Automatically: the tank is filled or emptied in known volume increments and
the measured level is written into V2H4 by the system. This method can be used when the level/volume relationship is not known.
The automatic mode can also be used if you can calibrate in volume units only: perform the volume calibration first, e.g. when filling the tank, followed by the linearization with »level registration« e.g. when emptying the tank. In this case, however, the »level« values displayed at V0H9 have no significance. The entry mode is selected at V2H1:
0 = manual,
1 = automatic.
At the end of the linearization the system measures in the volume/weight units selected, e.g. m
3
, ft3, t, %. Use the Table overleaf to enter your values.
Note!
You must enter at least two points:
- The first level point should be below or at the level of the sensor. If it is not and the level drops below the first point, the linearization will extrapolate back!
- The last level point should be greater than or equal to the maximum level to be measured.
- The maximum value is 9998; 9999 cancels the entry.
The maximum number of points is 30
When all points have been entered and the linearization is activated, the points are
sorted in rising volume and subjected to a plausibility check!

6 Analogue Outputs
This Chapter deals with the analogue output settings. The FMX 570 transmitter is designed for continuous measurement with control of:
one voltage output 0/2 ... 10 V
one current output 0/4 ... 20 mA
by the level or volume indication at V0H0. Table 6.1 and Fig. 6.1 summarize the parameters which control the analogue outputs and 10-step LCD display.
Units When defining the analogue range at V0H5/V0H6, the entries must be made in the units
used for calibration or if performed, linearization.

Output at fault The current and voltage outputs can be set to take on distinctive values if the self-
monitoring circuit of the Silometer FMX 570 transmitter triggers on finding a fault. The choice is made at V0H7, whereby:
0 = -10% of full scale ≤ -2 mA, -1V (default value)
1 = +110% of full scale +22 mA, +11V
2 = hold = value at fault held
Proceed as follows:

Caution!
Selecting option 2 effectively disables any fault recognition safeguards on the
analogue lines. Although the self-checking system functions, the alarm relay trips and the red alarm LED lights on the transmitter, all analogue devices connected to the Silometer appear to indicate correct measurements.

7 Trouble-Shooting
When the instructions in the manual have been followed correctly, the system must now function. Should this not be the case, the Silometer FMX 570 transmitter provides a number of aids for setting up and operating the module correctly. This Chapter contains the following:
Trouble-shooting tables, with error messages, meaning and response
Description of simulation operating mode for service and commissioning
purposes
Instructions for commissioning replacement electronic inserts, probes and
transmitters.
Repairs
7.1 Trouble-shooting tables
Fault conditionWhen the FMX 570 transmitter recognizes a fault condition:
the red fault LED lights and the alarm relay trips.
the output current (with the exception of operating mode 2) reverts to the
status selected in field V0H7, i.e. to -10%, +110% of the selected measuring range or last measured value (hold) - see Chapter 6.
A diagnostic message is given in Field V9H0:
If the cause of the fault has been rectified, the last diagnostic message is
retained in V9H1.
This message can be cleared by pressing the »E« key.
If the power fails, all relays de-energise.
WarningsWhen the FMX 570 transmitter has detected a warning:
the red fault LED flashes but the Silometer continues to measure
the alarm relay remains energised
the appropriate message is to be found in V9H0.
The error messages are listed in Table 7.1 in the order of their priority. If one fault is on display and a fault of higher priority occurs, the latter will appear at V9H0. The preceding message can be called by pressing the "plus" key.
Table 7.2, trouble-shooting, indicates possible configuration errors for the Silometer FMX 570.

This function is intended primarily for checking the correct function of the system and is selected and terminated at V8H0:
Enter 6 to simulate frequency, level, volume or current
Enter an operating mode to terminate simulation and resume normal
measurements.
Start and stop simulation

Four modes are possible:
Simulation of frequency, V9H6
Simulation of level, V9H7
Simulation of volume, V9H8
Simulation of current, V9H9.
When a value is entered at the appropriate matrix, the analog outputs are fed with the appropriate current and voltage and the other 3 simulation values are recalculated. Throughout the simulation the red alarm LED flashes to indicate that the instrument is no longer measuring, the alarm relay does not, however, trip.

7.3 Exchanging transmitters, probes and electronic inserts
Transmitter If the Silometer has to be exchanged, the replacement need not be recalibrated. Instead
it is usually sufficient to enter all the matrix values from the old into the new transmitter. The replacement will then measure correctly.
Where a special order has to be maintained, e.g. activation of linearization
after entry of parameters, this should be accounted for during re-entry or the steps must be performed separately.
For probes and electronic inserts, the procedure to be followed depends upon the type used.
Capacitance probes with EC 37 Z/EC 47 Z
For level measurement, provided the sensor constants were entered before calibration, it is not necessary to recalibrate the instrument when the electronic insert is replaced by one of the same type. On replacement:
the zero frequency (or offset) f
o
and
sensitivity S
for the range selected (default Range II) must be entered at V3H5 and V3H6 respectively. Fig. 7.1 shows where the information is to be found on the EC 37 Z and EC 47 Z inserts.
If a different range is selected, the transmitter must be recalibrated.
If the constants were not entered a recalibration is necessary.

DeltapilotProvided a »dry« calibration was made or the sensor constants were entered before
calibration, it is not necessary to recalibrate the instrument when the electronic insert is replaced. The measurement can be taken up again as soon as the new constants have been entered in the matrix.
If the old sensor constants were not entered, the system must be recalibrated.
For new sensor constants see table 2.2.
f
o
is the zero frequency (or offset)
•∆f is the sensitivity
For the Deltapilot, the zero frequency may also be read from V0H8 when the probe is unpressurized. This value gives slightly better accuracy, since it accounts for the orientation of the probe.

7.4 Repairs
Check the condition of the probes during regular maintenance inspections. If necessary, free them of build-up. Remember that all probes are sensitive instruments and must be treated accordingly.
Should the Silometer FMX 570 transmitter or its probes need to be repaired by Endress+Hauser, please send it to your nearest Service Centre with a note containing the following information:
An exact description of the application for which it was used.
The physical and chemical properties of the product measured.
A short description of the fault.
Caution!
Special precautions must be observed when sending probes for repair:
Remove all visible traces of product from the probe.
If the product can impair health, i.e. is corrosive, poisonous, carcinogenic,
radioactive etc., please check that the probe is thoroughly decontaminated.
If the last traces of dangerous products cannot be removed, e.g. product has
penetrated into fissures or diffused into plastic parts, we kindly ask you not to send the probe for repair.
