SERIES SC250
1 INTRODUCTION
The series SC250 are flowmeters for liquids, gases and steam.
They are very robust instruments prepared to work in extreme conditions.
They have local flow rate indication by means of magnetic coupling, with scales calibrated in
l/h, m
3
/h, kg/h, t/h, %, etc.
They can incorporate switches and/or electronic transmitters that allow to detect a specific
flow rate and provide a flow rate signal to a remote device.
2 WORKING PRINCIPLE
Based on variable area principle.
The flowmeter consists of a measuring tube and a float inside it. The flow pushes the float to
an equilibrium point. The area obtained between the float and the tube is proportional to the
flow rate.
The point of equilibrium depends on:
E = Force of the fluid flow
Pf = Weight of the float
Al = Free area of flow
where:
(Al = Ao, calibrated orifice area, - Af, float area)
Page 7
7
For flowmeters SC250H and SC250V, the force of the fluid moves the float and compresses
a spring. This allows that the float can return to its initial position regardless of its position
inside the tube when there is no flow.
These flowmeters can be installed in a horizontal pipe with flow from left to right or vice versa
or vertical pipe with upwards or downwards flow.
The SC250 model always works always in a vertical position with the flow direction from
bottom to top.
The equilibrium point is determined by considering the fluid force and the float weight.
Page 8

3 RECEPTION
The series SC250 flowmeters are supplied conveniently packaged for their protection during
transportation and storage, together with their instructions manual for installation and
operation.
The instruments are supplied tested in our calibration rigs, ready for installation and service.
Before installing the flowmeter, remove all the blocking elements.
With the instrument in its working position, move the float and check that the indicating
needle moves all over the scale and returns to zero.
4 INSTALLATION
Flowmeters models SC250 and SM250 must be installed in a completely vertical position
and with the flow direction upwards.
The flowmeter SC250V must be installed vertically (flow direction upwards or downwards).
The flowmeter SC250H must be installed in horizontal position (flow direction from left to
right or from right to left).
The instrument must be installed so that the flow direction indicated on the dataplate of the
instrument matches the flow direction of the fluid.
The “0” of the scale indicates flowmeter inlet, and the full scale indicates the flowmeter
outlet.
The model SM250 is a version of the flowmeter SC250 designed for liquids with high
viscosity, whose flows can not be measured with the standard SC250. This is achieved
thanks to its internal design and the use of special floats.
Page 9
9
It is important that the position is completely horizontal or vertical (depending on the model
of the instrument), given that deviations of about 5º can produce errors of about 8-10% of
the readings.
4.1 Valves
If the fluid to be measured is a liquid, it is recommended to install a regulating valve before
the flowmeter (see point 5.3).
In gas flow measurement, the valve position will depend on the calibrating pressure (see
point 5.1).
Valves should always be opened slowly to avoid water hammers.
4.2 Filters
The installation of a filter before the instrument is important, this will avoid possible
obstructions and breakdowns in the measuring system.
The mesh of the filter should be maximum 2 mm.
In case of having abundant magnetic particles in suspension, it is necessary to mount a
magnetic filter on the inlet of the instrument to avoid the accumulation of particles around the
float, which would make it to jam.
4.3 Straight pipe sections
In order to have stable readings, it is essential to avoid turbulences. To do this, it is
necessary to install the instrument in a straight pipe section. This section should have the
same inner diameter as the flowmeter. The required minimum distances upstream and
downstream of the sensor are the following:
Upstream 5 DN
Downstream 3 DN
These distances must be free of elements that can disturb the flow profile, such as elbows,
diameter changes, valves, etc.
Page 10
10
5 OPERATION
Once the meter is installed, the regulating valve should be opened slowly. The fluid flow will
move the float which, by means of magnetic coupling, moves the indicating needle.
Any variations of working conditions with respect to those when calibrated can induce
reading errors. The calibration working conditions are indicated on the instrument’s
dataplate.
5.1 Gas flow measurement
The working pressure and temperature are of maximum importance for correct gas
measurement as they directly affect the scale readings.
For example, if a meter is calibrated at 2 bar gauge and the working pressure is 1 bar gauge
there will be an error of about 22%.
In the same way, if working temperature does not match calibrating temperature, errors will
be induced in the flow rate readings.
In applications of gas flow measurement where the calibrating pressure of the instrument
corresponds to the inlet pressure, being higher than the atmospheric pressure, the
regulating valve must be installed downstream of the flowmeter. Thus, it is ensured that the
instrument works at calibrating pressure and a back pressure that keeps the float in
equilibrium is obtained.
NOTE: Scheme valid for gas flow
measurement applications with a pressure
higher than atmospheric. For gases at
atmospheric pressure, turn valves upside
down.
REGULATING VALVE
SHUT OFF VALVE
The flow should be adjusted by means of the regulating valve, while keeping the shut off
valve fully open.
Page 11
11
If the regulation is done using the shut off valve, in open circuits or at low gas flow in the
meter, the gas will expand which will sharply diminish its density, providing very serious
reading errors.
If the flow is regulated by the shut off valve, the float usually experiences an oscillating
movement which produces a shut off action until sufficient pressure is gained to overcome its
weight. The sudden fall of pressure, when the gas escapes, will make it fall. This cycle is
repeated generating an oscillating measurement (resonance).
In applications where the gas outlet is at atmospheric pressure, install the regulating valve
upstream of the flowmeter if the flowmeter was calibrated at atmospheric pressure. The shut
off valve is then installed downstream of the flowmeter and it should be fully open.
The valve opening procedure should be as following:
- With the regulating valve closed, fully open the shut off valve.
- Gradually open the regulating valve until the desired flow rate.
And for closing:
- Close the regulating valve gradually until zero flow rate.
- Fully close the shut off valve to isolate the flowmeter.
Operating in a different way may involve water hammers that can damage the meter reading
or generate instabilities.

2. Float
3. Piston
4. Piston locking circlip
5. Guide cylinder
6. Circlips for locking upper float stop & guide cylinder
Page 12
12
When measuring low pressure gas flow with AISI 316L floats, oscillation of the float often
occurs, which makes it very difficult to read the flow rates. In these cases it is recommended
to install a damper in the instrument.
The damper consists of a piston mounted inside a cylinder, closed at its lower end. The
compression forces of the gas absorb the floats oscillations, maintaining it stable in the
reading point.
Close the valves during work stops at the end of the working day in order to avoid sudden
surges when started up. If the float hits the stops sharply this could cause damage to the
meter.
5.3 Liquid flow measurement
When measuring liquids the regulating valve should be installed as shown in the following
figure.
Being the shut off valve partially open, open the regulating valve slowly until the needle of the
indicator housing shows a low flow rate. Then also open the shut off valve slowly in order to
get rid of the air and then progressively fully opened.
The required flow rate is then regulated by using the regulating valve.
Close the valves during work stops at the end of the working day in order to avoid sudden
surges when started up. If the float hits the stops sharply this could cause damage to the
meter.

LIMIT SWITCH AMD
6 INTRODUCTION
The AMD limit switch can be used to generate an alarm or an operation when the flow rate
that the instrument is measuring reaches a preset value on the scale plate.
The AMD limit switch consists of a NAMUR slot type inductive sensor, that is actuated by a
vane. Given that there is no physical contact in the operation, the limit switch has no influence
on the indicator needle movement.
An instrument can be equipped with one or two sensors, depending on the number of points
to be detected. A NAMUR amplifier with a relay output can be supplied as an option.
7 OPERATION
The indicator needle moves together with the vane mounted on its shaft. When the vane
enters into the slot of the sensor, the limit switch changes its state.
The sensor is mounted on a support which includes a switching point indicator that indicates
the switching position. The indicator, that is below the scale plate, can be seen through the
scale slot.

To move the limit switch needle, the circular fixing nuts have to be slightly loosen by turning
them to the left, without removing the scale plate (see the figure on the next page). After
that, place the switching point indicator in the required scale value, and fix it again with the
screw.
As standard, when the instrument has one AMD, it comes configured as a minimum limit
switch.
8.5 Electrical connection
Do it according to section 9.
8.6 Mounting
Slide the scale plate into the slot until it stops as shown in the figure. Mount the cover with
the four screws "Allen" M5 and the plastic washers.
9 ELECTRICAL CONNECTION
To gain access to the electrical terminal block, the scale plate must be removed. To do this,
slide it to the left by the guide and free it.
In order to make the electrical connection of the instrument, the limit switch has a screw
terminal strip.
For the electrical installation it is recommended to use multiple conductor cables with
individual cable sections in the order of 0.25 to 0.5 mm
2
in order to make it easier to
connect.
Before starting the installation, check that the cable glands are the right size for the cables to
be used, this will guarantee the instrument will stay watertight. The supplied M16 cable
glands are for cables with outside diameters between 6 mm and 10 mm.
Peel the outside insulation to free the inner cables. It is recommended to tin the ends of the
wires to avoid loose ends. Next, feed the cables through the cable glands, and connect to
the corresponding screw terminals. Last, tighten up the cable glands so that they maintain
their ingress protection.

LIMIT SWITCH AMM
10 INTRODUCTION
The AMM limit switch can be used to generate an alarm or an operation when the flow rate or
the instrument is measuring reaches a preset value on the scale plate.
It consists of a micro-switch driven by a cam mounted on the indicating needle.
An instrument can be equipped with one or two micro-switches, depending on the number of
points to be detected.
11 MOUNTING THE LIMIT SWITCH IN AN EXISTING EQUIPMENT
In order to add an AMM limit switch to an existing device, follow the steps shown below.

11.5 Electrical connection
Do it according to section 12.
11.4 Switching point adjustment
To adjust the switching point, loosen slightly the cam’s grub screw (C) and turn the cam on
the shaft until the required switching point is achieved.
To turn the cam on the shaft, do not hold the shaft by the indicating needle, as this may
move the needle on the shaft. The shaft should be held directly.
For the models SC250, SC250V/BD, SC250H/DES and SM250, if the cam is turned in the
“A” direction, the acting point will move away from the zero point of the scale. If the cam is
turned in the “B” direction, the acting point will move towards the zero point of the scale.
For the models SC250V/DAB, SC250H/ED, if the cam is turned in the “A” direction, the
acting point will move towards to the zero point of the scale. If the cam is turned in the “B”
direction, the acting point will move away from the zero point of the scale.
Once the cam is in its position, making sure that it rests on the follower of the micro-switch
lever, and the grub screw (C) has been tightened, the correct working of the limit switch
should be verified by turning the indicating needle shaft and checking the switching at the
required point.

12 ELECTRICAL CONNECTION
In order to make the electrical connection of the instrument, the limit switch has a screw
terminal strip.
For the electrical installation it is recommended to use multiple conductor cables with
individual cable sections in the order of 0.25 to 0.5 mm
2
in order to make it easier to
connect. Loose cables should not be used given that they can affect the seal of the cable
glands. It is better to maintain the mains cables separated from the cables with low level
signals.
Before starting the installation, check that the cable glands are the right size for the cables
to be used, this will guarantee the instrument will stay watertight. The M16 cable glands
used are for cables with outside diameters between 6 mm and 10 mm.
Peel the outside insulation to free the inner cables. It is recommended to tin the ends of the
wires to avoid loose ends. Next, feed the cables through the cable glands, and connect to
the corresponding screw terminals. Last, tighten up the cable glands so that they maintain

TH7 TRANSMITTERS
13 INTRODUCTION
TH7 transmitters are microprocessed electronic position transducers. The instrument uses
the Hall effect to capture the field of a magnet. The resulting signal, after the micro-controller
processing, is converted into a current signal of 4-20 mA in a 2-wire loop. This signal is
proportional to the flow rate.
14 MODELS
14.1 TH7
It is a 4 to 20 mA transmitter proportional to flow rate that incorporates a digital output
configurable as synchronized pulse output or alarm output. 4 mA corresponds to beginning
of the scale. 20 mA corresponds to full scale.
The cut off value can be programmed (see section 20.3 in page 32). By default, the cut off
corresponds to the first point on the scale after the zero point.
14.2 TH7H
It is a TH7 transmitter that incorporates HART protocol compatibility. With this protocol the
user can change the measuring range of the 4-20 mA loop, and data like flow rate and
accumulated volume.
14.3 TH7T and TH7TH
They are the equivalent models to those of the sections 14.1 and 14.2, but in addition they
include a 8-digit totalizer (7 entire numbers and 1 decimal).

16 ELECTRICAL CONNECTION
For the electrical connection, the transmitter has a screw terminal strip.
For the electrical installation it is recommended to use multiple conductor cables with
individual cable sections in the order of 0.25 to 0.5 mm
2
in order to make it easier to
connect.
A twisted pair wiring should be used to avoid electrical interferences in the 4-20 mA loop. In
some instances, shielded cable may be necessary.
Before starting the installation, check that the cable glands are the right size for the cables to
be used, this will guarantee the instrument will stay watertight. The M16 cable glands used
are for cables with outside diameters between 6 mm and 10 mm.
Peel the outside insulation to free the inner cables. It is recommended to tin the ends of the
wires to avoid loose ends. Pass the cables through the cable glands and screw down in the
corresponding positions of the terminal strip. Once the wiring is finished make sure that the
cables are well gripped by the cable glands to maintain the ingress protection.
The cable glands must be always closed. Entry of dust or some types of vapours can
damage the internal system of bearings and therefore the equipment.
To help in the wiring of the equipment, the description of the terminals is marked on the
printed circuit next to the terminal strip.
15.6 Mounting
Slide the scale plate into the slot until it stops as shown in the figure. Mount the cover with
the four screws "Allen" M5 and the plastic washers.
Page 25
25
The connection is made in the terminal block. The positive terminal of the power supply is
connected to the position + and the positive terminal of the load in the position -. The
negative terminals of the power supply and the load are connected together. The instrument
works in a 2-wire system, that is, the supply and signal line is the same. It is recommended
to use a twisted pair wiring or shielded cable to avoid interferences in the current loop.
16.2 Digital output
The digital output is connected in the positions D and S of the terminal block. The output is
an N channel MOSFET transistor isolated from the rest of the circuit and potential free. The
S terminal is the source and the D terminal is the drain.
By means of the Winsmeter TH7 software, the digital output can be programmed as pulse
output or alarm output (see section 20.3 in page 31).
Before connecting the power supply, you must be sure that the supply voltage is the correct
one for the installation. The power supply voltage is indicated on the label of the transmitter.

Example of the connection of the pulse output to a PLC
16.3 Reset input
The terminals marked as RESET are a reset input for the totalizer. It can be connected to a
normally open potential free contact. It is important that the contact works well with low level
voltages, to avoid noise effects.
Note: The reset terminals are not isolated from the rest of the circuit. They must not be
connected to other equipment.

18 HART TRANSMITTERS
The TH7H and TH7TH transmitters have a modem for HART communication.
TH7H transmitters are fully compatible with the HART Server software from HART
Communication Foundation.
Tecfluid S.A. do not guarantee that the TH7H transmitter is compatible with the different
servers on the market.
When connecting the transmitter, an external resistor (R ext.) should be included. Its
minimum value needs to be 200 Ω, and the maximum value depends on the power supply
as follows:
In this case the power supply voltage needs to be 18 VDC minimum.
In order to establish HART communication, it is necessary to connect a terminal or PC with a
HART modem, in one of the points indicated in the following figure.

19 “WRITE PROTECT”
The instrument has a jumper that can be used to avoid changes in the configuration. When
the jumper is connected the instrument can be configured via HART. When the jumper is
removed, “Write Protect” is activated for HART, thus avoiding any changes in the
configuration.
20 ASSOCIATED SOFTWARE WINSMETER TH7
By means of this associated software the transmitter can perform the following functions,
working in a comfortable and intuitive way.
Complete re-calibration of the transmitter according to the scale of the instrument.
Programming of 4 and 20 mA values
Filter and cut off programming
Totalizer reset or adjustment of a desired value
Configuration of the digital output as pulse output or alarm
Such software can be downloaded from section “Downloads” of the Tecfluid S.A. website.
NOTE: Programming via USB can only be done in non-classified area.
20.1 USB cable connection and drivers installation
Extract the files from the winsmeterTH7.zip to a new system folder.
Execute the Setup.exe file and follow the steps for the installation.
In order to connect the converter to a computer an USB cable is required. This cable is type A
at one end and mini USB type B at the other (cable not supplied).
The ends of the cables can be seen in the picture.
The first step to make the connection is to open the cover of the indicator housing by removing
the four screws "Allen" M5 and plastic washers on the back of the housing.
After removing the graduated scale plate sliding it through the slots, the USB connector is
visible at the bottom of the housing.
Page 30
30
Connect the USB cable at one end to the transmitter and at the other to the computer where
the software is installed.
Power on the electronic converter.
Execute the program WinsmeterTH7 following the sequence Start – Programs – Tecfluid S.A. WinsmeterTH7.
20.2 Port connection
In the "Port" section, choose the appropriate port for the converter. This will appear with the
name of the port followed by TH7 and its serial number. Then click "Open".
Page 31
31
Once the port is open, the button "Open" in the "Calibration" and “Programming” sections
activates.
20.3 Access to Calibration and Programming
In order to change data in the tab "Calibration", you must enter a password.
The default password is calib, and it can be changed using the boxes on the right of the
"Calibration" section.
Likewise, to change data in the tab "Programming" it is necessary to enter the password which
by default is program. This can be changed using the boxes on the right of the "Programming"
section.
Page 32
32
Once the password is written, press "Enter" or "Open", and the Calibration or Programming tab
will open. At the bottom of each section the text "Calibration tab open" or "Programming tab
open" will be displayed
To enter the Installation window, just click the corresponding tab.
In the calibration window a complete re-calibration of the transmitter according to the scale
plate can be done.
The first step is to choose the scale units, then the specific units.
In the combo N. points the number of points with which the calibration will be performed is
selected. The minimum is 10 and the maximum 16.
With these data, the boxes P0 ... P10 to P16 are filled with the values of the scale in which the
adjustment will be made.
To perform the calibration, the instrument must be in its operating position.
Depending on the instrument in question, move the float or the disc until the needle points
each calibration point, and press the "Calibrate" button of the corresponding point.
Once calibrated every point, to send all the data to the transmitter TH7, click the "Send" button.
The data is then stored in the transmitter memory.
Page 33
33
Changing the parameters of this screen, (see previous page) you can program the different
functions of the equipment.
In the box Totalizer units power can be selected. The power allows to multiply or divide by a
factor multiple of 10 the totalizer speed as well as the pulse output.
By default, with the power = 0, the totalizer and the pulse output indicate the scale units, ie, if
the scale of the instrument is in litres / hour, the totalizer indicates liters and the digital output
gives one pulse for each litre.
If, for example, the power is programmed to 1, the totalizer and pulse output will run 10 times
faster. If a power = -2 is programmed, they will run 100 times slower.
In the box Digital output this output can be configured as pulse output or as alarm. In the latter
case, the activation and deactivation values for the alarm can be programmed.
In the box Current loop the values of flow rate equivalent to 4 and 20 mA can be programmed.
These values do not have to be the beginning of scale and end of scale values.
In the box Flow rate the values of cut off and filter can be changed.
The cut off is the value below which the TH7 transmitter will consider zero flow rate, and
therefore the analog output will give 4 mA and the digital output will be deactivated if it is
programmed in pulse mode.
The filter offers stable current loop readings despite fluctuations in the flow reading. It is
programmed in seconds, between 1 and 8.
Likewise, to enter into the programming window, just click the corresponding tab.
Page 34
34
To program this data to the transmitter, press the “Send” button. The programming data will be
stored in the memory of the transmitter.
Regardless of the programming process, in the box Totalizer value the value of the totalizer can
be changed.
20.4 Visualization
When the communication with the computer port is established (see section 20.2), the tab
"Visualization" opens. This tab lets you view real-time flow rate, totalizer and velocity values, as
well as the current value of the analog output and the status of the digital output if configured
as alarm.
It is an intuitive tool to verify that the instrument has been installed and programmed correctly.
20.5 Firmware updates
New firmware updates can be published in the website. These updates contain improvements
or bug fixes that make the equipment operates at best conditions.
The updates can be downloaded from the section “Downloads” of Tecfluid S.A. website.
Page 35
35
To update the equipment, go to menu “Firmware” - “Update”, and a screen with the button
“File” will appear. Pressing this button system can be accessed. The downloaded file has to be
searched there.
Once the file is selected, press the “Program” button. A message “Programming device” will
appear.
The process takes about 90 seconds, after which the message “Device programmed” will
appear.
From this moment, the transmitter already has the new version of Firmware.

21 MAINTENANCE
21.1 Series SC250
To perform the maintenance of the meter, it is necessary to remove some parts of the
flowmeter. Check below drawings for reference.
In flowmeters up to DN80 remove the circlip (6) which locks the top float stop (7). Then
remove the float stop (7). The float (2) can now be extracted. Check it is in perfect condition.
For flowmeters DN100 or larger sizes, remove the screw (9) which holds the float end (8).
Then remove the float end (8). The float (2) can be extracted from the top of the flowmeter.
Clean the magnetic cylinder (10).
In both cases also check the status of the calibrated orifice (3).
They should have no impact or scratches. Also check that there has been no chemical
attack.
If the float (2) is in poor condition it must be replaced. If the calibrated orifice (3) is also in
poor condition, the meter body (5) and float (2) should be replaced. In both cases we
recommend to re-calibrate the instrument in Tecfluid S.A. facilities.
To remove adhered chemical dirt to the float (2), metering tube (5) or calibrated orifice (3),
clean the parts with suitable products or solvents and soft brushes, never use metallic tools.
Follow the above steps in reverse to reassemble the equipment.
Page 37
37
21.2 Float for SC250 with hygienic design
Two special tools are necessary to disassemble the float (2) from the flowmeter. They can be
supplied on demand by Tecfluid S.A.
These tools fit into the side guides of the float (2) and of the float end (8).
Once the tools have been fitted into their respective guides, turn the float end (8) as if it was
a nut. That way the float (2) will be separated from the float end (8), and the float can be
taken out from the top of the meter and the float end from the bottom.
Clean the inside of the metering tube and the float (2).
To remove adhered chemical dirt, clean the parts with suitable products or solvents and soft
brushes, never use metallic tools.
Follow the above steps in reverse to reassemble the equipment, making sure that the O-ring
(10) is correctly placed between the float (2) and the float end (8). Tighten the float end (8)
moderately onto the float (2).
If you are interested in acquiring the special tools in Tecfluid S.A., please indicate for which
nominal diameter they are required.
Page 38
38
21.3 Potential problems with the metering tube
21.3.1 Jammed float
In flowmeters up to DN80 a possible cause is that the float upper guide (4) or the lower one
(1) are bent due to a water hammer. To solve this, remove the circlip (6) which locks the top
float stop (7). Then remove the float stop (7). The float (2) can now be extracted. Align the
guide rods and manually check that the movement is good without rubbing.
For flowmeters DN100 or larger, the cause can be that the magnetic cylinder (10) is bent or
dirty. To solve this, extract the float (2) from the flowmeter by removing the screw (9) which
holds the float end (7). Then remove the float end. Extract the float (2) from the top of the
flowmeter and straighten or clean the magnetic cylinder (10).
Follow the above steps in reverse to reassemble the equipment.
The float may also become clogged by accumulation of metallic particles around it due to
the float magnetic field. In this case disassemble the float (2) following the above
instructions, clean it, and install a magnetic filter on the inlet of the meter, or just a normal
filter depending on the size and nature of the particles.
21.3.2 Bent top float stop
If the top float stop (7) is bent due to a water hammer, disassemble it following the
instructions of the section 21.1. If it is possible, straighten it and check its alignment.
Otherwise change it for a new one.
21.3.3 Lack of magnetic field
Disassemble the float (2) as indicated in section point 21.1. Check if the float has suffered
chemical aggression and if so the permanent magnet has been affected. If this is the case,
the float must be replaced and the flowmeter will have to be re-calibrated in Tecfluid S.A.
facilities.
21.3.4 Damaged calibrated orifice and / or float
Check that they do not show any impacts or scratches. Also check for any chemical attack.
If the float (2) is in bad condition it must be replaced. If the calibrated orifice (3) is damaged,
the metering tube and the float must be replaced. In both cases the flowmeter has to be recalibrated in Tecfluid S.A. facilities.
Page 39

21.4 Potential problems with the indicator housing
21.4.1 The indicator pointer rubs on the reading scale
To remove the cover, remove the four screws "Allen" M5 and plastic washers, in the back
side of the indicator housing, using a 4 mm Allen key.
Rubbing normally happens if the meter has been hit or dropped. Simply straighten the
pointer (2) by bending it slightly until it is separated between 2-3 mm from the reading scale
surface (1)
21.4.2 Deviation of the zero on the scale
When the indicator pointer (2) does not point zero in its rest position, place the flowmeter in
its real working position on top of a non-magnetic table. If when the float is moved the
pointer moves but does not return to 0, check that the pointer hub (3) is firmly attached to
the pointer shaft (7). If it isn’t, secure the pointer hub (3) onto the conical tip (7) of the shaft
by tapping it lightly and carefully.
If the pointer hub is fixed, make the indicator pointer coincide with the 0 on the scale using
the frontal adjusting screw (4) on the indicator pointer. Make sure that the shaft (7) is held
fast so as not to be bent or damaged
Check that there is no rubbing between the pointer movement system and the cables
connected to a limit switch or transmitter.

21.5 AMD limit switch maintenance
21.5.1 Electrical verification
Check that the voltage at the terminals + and - is over 7.5 V when the vane is in the slot.
Connect a multimeter with the scale in DC mA, in series with the terminal +.
Verify that the current is less than 1 mA when the vane is in the slot, and more than 3 mA
when the vane is out of the slot.
If you do not have the NAMUR amplifier, the current can be checked using the following
circuit diagram:
If you do not have the AMD sensor, the operation of the amplifier can be checked using the
following circuit diagram:
With the potentiometer the current of the NAMUR amplifier can be modified. The switching
point must be between 1.2 mA and 2.1 mA. That is, with the current below 1,2 mA the
output relay must have a state and above 2,1 mA the output relay must have the other state.
21.6 AMM limit switch maintenance
No special maintenance is required.
21.7 TH7 transmitter maintenance
No special maintenance is required.
