INTRODUCTION

INTRODUCTION

This manual sets out to help you understand and deal with the alarms that appear on the Console
when the loom diagnostics detects a problem or certain events that automatically generate messages
on the Console.
This manual has been written specifically for the Alpha loom with conventional brake/
clutch transmission and the 2004 system using RTC 8010.xxx firmware. However, where at
all possible, we have also added troubleshooting details for the Alpha loom with the 2003
system.
To discover whether your loom is fitted with the 2003 or 2004 system, check the let-off box (at the
rear of the loom, on the right): if it has lots of connections, the loom is fitted with the 2003 system; if
the let-off box has just one connector and two large black or grey tubes, the loom is fitted with the
2004 system.

Intervention and use of this manual

Certain rules must be followed when troubleshooting to ensure that you adopt a logical and systematic
process.
always make a note of the loom serial number
note the date and time the alarm was given
check the alarm code and follow the instructions in this manual
make a note of the loom’s behaviour and any further alarms.

As a result, if you need to contact our customer service helpline, these data will help our operator to
get a proper idea of the problem and gradually understand the operations required. In other words,
you’ll get a faster and more precise service.

NB: while you may have been trying to solve a (complex) problem for several hours, the
person on the other end of the line has no idea what you’ve done and what happened as
a result, and doesn’t have the loom in front of him/her.

Next to the board and component codes in this manual you’ll find a table reference, as follows:
(table C-2)
indicating that the component in question can be found in Table C, position number 2. The tables are
enclosed at the end of this manual in A3 format. In the example above: the ISC board.

N.B.: if the loom is fitted with the 2003 system, the table references are approximate, as the
tables shown here refer to looms fitted with the 2004 system.

This manual often tells you to replace a board or component. The Annex section at the end of the
manual explains how to replace the various elements and indicates the procedures required if a
memory board, plus the hardware settings required before inserting a new board. If not specified, it
means that the component can be simply replaced by reconnecting it in the same way as the
previous one.

The various boards on the loom have leds that warn when a device is enabled/disabled or that a given
circuit is OK, and also help us when diagnosing a problem.
Fuses are always fitted on each board to protect specific circuits.
The warnings provided by the led diodes on the boards and the Console diagnostics menu leds
(virtual) are explained at the start of this manual.

 ALARM AND TROUBLESHOOTING MANUAL
INTRODUCTION

How to read and interpret the alarms

Every alarm that appears on the Console has an identifying code and a brief description, in the
following format:

error number

error name device responsible for

generating the alarm

alarm level
key to press to quit
the alarm page

number of active alarms

All you need do is to find the same identifying code in this manual, read the explanation and then
carry out the immediate steps suggested as the remedy.
Example:

3 Memory Card not inserted

Meaning:
You’ve pressed the Memory Card menu access key without actually inserting the MC in its slot
on the Console.

Remedies:
Insert the Memory Card correctly.

In the red alarm window, the alarm level indicates the critical importance of the alarm.
The level logic is shown below. NB: the lower the level, the more critical the alarm.
For example:
Level 0 high priority
Level 1 medium / high priority
Level 2 medium / low priority
Level 3 low priority.
If there are several alarms at the same time, but with different levels of priority, the one with the
highest priority is shown first.
The table below defines the alarm groups for each device and their relative levels.

5 01 - 06 - 2005
 ALARM AND TROUBLESHOOTING MANUAL
LED AND FUSE TABLES

If there’s a fault, “E” appears on the display, alternating with a number.

E0 NO ERROR

E1 CHANNEL A ZERO CALIBRATION ERROR

Meaning: On start-up, the drive has been unable to calibrate the current sensor automatically.
The result falls outside the accepted range.
Remedies: Replace the drive.

E2 CHANNEL B ZERO CALIBRATION ERROR

Meaning: On start-up, the drive has been unable to calibrate the current sensor automatically.
The result falls outside the accepted range.
Remedies: Replace the drive.

E3 HIGH TEMPERATURE ERROR

Meaning: The dissipator temperature is higher than 65 °C (approx.). The automatic protection
has tripped.
Remedies: Check the correct drive dissipation.

E4 HIGH BUS VOLTAGE ERROR

Meaning: The internal direct voltage (motor supply rate) is over the accepted max limit of
360 V on switching-on or above 470 V when the motor is running.
Remedies: Check the drive power supply rate.
Replace the drive.

E5 LOW BUS VOLTAGE ERROR

Meaning: The internal direct voltage (drive motor rating) is below the accepted max limit of
265 V on switching-on or below 250 V when the motor is running.
Remedies: Check the drive power supply rate.
Replace the drive.

E6 HALL DETECTORS COMBINATION ERROR (INTERRUPT)

Meaning: The combination read by the 3 Hall detectors has provided an incorrect reading.
The valid combinations are 001, 010, 100, 011, 110 and 101. Incorrect combinations
are 111 and 000.
Remedies: Check the cable and connector connections.

E7 IMAX PROTECTION ERROR (HARDWARE)

Meaning: The short-circuit protection device on the motor piloting has tripped. There’s a
short-circuit in the power cable leading to the motor or the piloting has failed
inside the drive.
Remedies: Switch the drive off and back on again; replace the drive if the error persists.

6 01 - 06 - 2005
 ALARM AND TROUBLESHOOTING MANUAL
LED AND FUSE TABLES

E8 INCORRECT END CONVERSION ERROR

Meaning: Problem within the drive firmware.
Remedies: Replace the drive.

E9 BLOCK I2T ERROR

Meaning: The motor thermal protection has tripped (calculated by the drive). The motor is
being used above the max limit. The drive is efficient.
Remedies: Check the motor absorption rate, check that the motor shaft turns freely. Replace
the motor if necessary.

E 10 MOTOR THERMOSTAT ERROR

Meaning: The thermal protection (thermal sensor) inside the motor has tripped.
Remedies: Check the motor absorption rate, check that the motor shaft turns freely. Replace
the motor if necessary.

E 12 NO SLAVE REFERENCE ERROR

Meaning: The drive is working in slave mode. It has not received the space reference from
the Master via CAN-BUS for more than 100 ms. Standard updating: every 1 ms.
Remedies: Check the connections.

E 13 CAN-BUS OFF ERROR

Meaning: Too many errors on the CAN-BUS. The drive cannot work.
Remedies: Check the CAN-BUS connections.

E 14 NO MOTOR ENCODER ERROR

Meaning: The motor encoder is not working. This test is carried out by comparing the
rotation with the Hall detectors.
Remedies: Replace the motor.

E 15 OVER MAX SPACE ERROR

Meaning: The motor is working with space tracking with the loom encoder multiplied for an
electronically calculated transmission rate. If the error in the space between the
loom encoder and the motor encoder is higher than the max calculated value,
the drive will stop and generate this error.
Remedies: Make sure the motor turns freely. Check the max accepted loads.

>I MAX:
Normally off, this comes on to warn that the module current overload has tripped, i.e. too much
current is being supplied to the motor. If this trips, switch the loom off and back on again to reset.

BRAKE:
This indicates the status of fuse F1 and is normally on. The light tends to dim for short moments
during the braking of the motor only, indicating that the module section regarding the braking of the
motor is OK.

F1: protects the motor braking resistance circuit in the module (see green “BRAKE” led above)

F2: protects the internal microprocessor service circuits: if the fuse blows, the display goes blank.

2 INPUT & OUTPUT TABLES

The INPUTs and OUTPUTs are the inputs and outputs on the boards, i.e. the data that are sent to a
board (INPUT) or the commands sent by a board (OUTPUT).
If you control the signals entering and leaving a board, at the various points, you can establish
whether the problem lies with the board or the loom.
The inputs/outputs are shown as follows:

lamp on status: active

lamp off status: not active

symbol input signals arriving at the board (input)

symbol output signals leaving the board (output)

For example, if you press the slow motion button and nothing happens, you can try checking that the
button signal actually reaches the IOS board; if not, the problem lies with the buttons. If, on the other
hand, the signal does reach the board, the problem is definitely not caused by the buttons.
The inputs and outputs can be displayed on the Console by inserting a level 3 Memory Card and then
following these steps:

press - - (in order) from the main menu;

the following menu appears:

1: CAN-BUS status: green indicates that the CAN-BUS is OK; red, there’s a problem
2: incorrect CAN-BUS input data
3: incorrect CAN-BUS output data
4: the data/second rate managed by the CAN-BUS
5 - 6: press key the Host Computer / Jacquard communication test is carried out
green: communication OK
red: problems

 ALARM AND TROUBLESHOOTING MANUAL
LIST OF ALARMS

1048 No pick-finding as loom in movement

Meaning:
Before pick-finding, the RTC board checks that the loom isn’t already in movement; if it is, it
generates this warning.

Remedies:
Check that the loom is at a standstill before carrying out any movements; if not, find the
cause for its movement.
Mechanical problems on the loom brake, check the state of the brake coil and the electrical
connections
Replace the BCS board (table C-6) that feeds the brake.
Check that there’s 160 V DC between point 10 on connection J01 on the BCS board (table
C-6) and the earth. If this isn’t so, check for 160 V DC between point 3 on connection M9 of
the VX032 board (table D-6) and the earth, and if there still isn’t 160 V DC, replace the
VX032 board (table D-6).
Check connections J03 - J01 - J02 on the JDB board (table D-11).
Replace the encoder if the problem persists.
Replace the RTC board (table B-3).

1049 No pick-finding as in zone prohibited by encoder

Meaning:
After pressing one of the pick-finding buttons the loom hasn’t moved because it’s in a position
where this type of movement isn’t allowed.
The rapiers could be inside the shed.
The system checks the encoder degrees before carrying out the movement; it has prevented
pick-finding to avoid the risk of broken warp threads.

Remedies:
Carry out a slow motion cycle and take the rapiers out of the shed, then repeat the pick-
finding.
If the problem persists, check that the encoder degree count on the Console is compatible
with the mechanical position of the loom. If this isn’t so, check that the cross-over of the
warp takes place in the correct position when you move the loom manually. If this happens
it means that the loom is mechanically synchronised with the shedding machine and therefore
the problem is of an electrical nature.
Check connections X825 and X811 on the SDI board (table D-12).
Check connections J1 and J2 on the CSC board (table C-3).
Check connections J1 and J2 on the ISC board (table C-2).
Check connections J16, J40 and J12 on the JDB board (table D-11).
Check connections J10 on the RTC board (table B-3).
Replace the main encoder.
Replace the RTC board (table B-3).
Replace the SDI board (table D-12).

1050 No pick-finding by Jacquard

Meaning:
When you press a pick-finding button, the machine doesn’t move because the Jacquard
blocks this movement.

41 01 - 06 - 2005
 ALARM AND TROUBLESHOOTING MANUAL
LIST OF ALARMS

One of the pick-finding buttons with an “X” will appear on the Jacquard controller (STÄUBLI)
display.

Remedies:
Press “X” on the Jacquard controller and the alarm normally disappears and you can then
carry out the pick-finding.
Contact the Jacquard manufacturer.

1051 Pick-finding stopped as motor blocked

Meaning:
This indicates that, despite the fact that the system has detected that the slow motion motor
control remote switches have tripped, the system hasn’t received any signal from the main
encoder.
Therefore the loom hasn’t finished the pick-finding because the slow motion motor is blocked,
or the system hasn’t received the degrees from the encoder during slow motion or pick
finding.

Remedies:
ALPHA 2004
Check that the encoder is connected to connector XLS14 on the LH side of the loom.
Check the pins inside the connector.
Check that the contacts on the slow motion remote switches KM03, KM04, KM08, KM09
(table C-34-35-37-38) aren’t damaged.

Replace the VX032 board (table D-6).
ALPHA 2003
Check that the encoder is connected to connector X423 on the LH side of the loom.
Check the pins inside the connector.
Check that the contacts on the slow motion remote switches K3 (SM motor forwards), K4
(SM motor in reverse), K8 (SM motor low speed), K9 (SM motor low speed) aren’t damaged.
If a 2003 system, you need to check other points, as the diagnostics is less precise.
Check whether the remote switches become excited when you press the pick-finding button.
Check that when the coils are excited, 24 V AC reaches the remote switches at pins K3, K4,
K8, K9 A1-A2.
If there’s 24 V AC and the remote switch doesn’t close, replace it because faulty.
If there’s no 24 V AC, check pins 5-6-8-9 (power supply remote switch coils) on connector
X160 on the VX035 board and the earth.
Replace the VX035 board.

Replace the VX032 board (table D-6).

1052 Pick-finding not done because in zone prohibited by dial

sensors

Meaning:
After pressing one of the pick-finding buttons the loom hasn’t moved because it’s in a position
where this type of movement isn’t allowed.
The rapiers could be inside the shed.
The system has checked the dial sensors before carrying out the movement and has blocked
the pick-finding.

Remedies:
Carry out a slow motion cycle and take the rapiers out of the shed, then repeat the pick-
finding.
Take the loom (again manually) to zero degrees, in this position all the sensors on the dial
(nonius) should be on, if this isn’t so check:
the connection J08A on the IOS board (table E-1 / table F-1): there should be 24 V DC
between points 1 and 3; if not check connection J10 on the IOS board.
Check each movable connection near the proximities.
Check the air gap between the proximities and the metal section in the nonius (0.5 mm).
Check that the nonius turns on its own axis and isn’t off-centre, thus altering the air gap to
suit the position.
Replace the faulty proximity.
Replace the IOS board (table E-1 / table F-1).

1053 No encoder zero

Meaning:
With each turn of the loom, the main encoder sends a pulse called the “zero pulse” that
should coincide with the mechanical zero of the loom. This is needed to start the loom
position count again and to synchronise the count for all the boards that need to know the
position of the loom.
This alarm is generated when the loom hasn’t received the zero signal during slow motion.

Remedies:
Check the cabling of the encoder, especially the zero signal at pin 2 on connector J10 on
the RTC board.

43 01 - 06 - 2005
 ALARM AND TROUBLESHOOTING MANUAL

1054 No loom degrees

Meaning:
If there are zero loom degrees, check whether the encoder is out of its tolerance by +/- 2
degrees (accepted field: 358 and 2).
When you press the start-up buttons, the machine doesn’t detect the loom degrees.

Remedies:
Check the cabling of the encoder, especially the zero signal at pin 2 on connector J10 on
the RTC board.
Check the encoder drive belt.
Check the main motor drive belt.

See also alarm 1056.

1056 CAN-BUS error

Meaning:
This means that there are communication problems on the CAN-BUS line.

Remedies:
Follow the CAN-BUS cabling control procedure described in table “I”.
Go to the two CAN-H and CAN-L terminals on any board (table “I”) with the control box
switched off and you should find a resistance of 60 ohm.
There are 2 end resistances on the CAN line and these should have a resistance of 120
ohm:
on the IOS board (always) (table E-1 / table F-1)
on the dobby board (if a dobby loom)
on the VX032 board (table D-6) at connector M10 (if Jacquard shedding machine loom with
a 2003 system)
on the JDB board (table D-11) at connector J39 (if Jacquard shedding machine loom with a
2004 system).
Given that the 2 resistances are in parallel, you should have a resistance of 60 ohm when
all the circuit branches are connected.

84 01 - 06 - 2005
 ALARM AND TROUBLESHOOTING MANUAL
LIST OF ALARMS

ignored. This means that if you set a weft density of less than 0.1 wefts/cm, there will be no
warnings and the drive will automatically adopt 1.0 wefts/cm.
The Console limits, however, are different: min 0.1 wefts/cm and therefore, when you go
below this limit, there will be a warning: “Value out of range 0.1 - 200”.
This alarm should, therefore, never appear, as the Console limits intervene first.

2064 Set density too high

Meaning:
This alarm isn’t used as the drive hasn’t got a max wefts/cm limit.
The max limit is set in the Console: max 200 wefts/cm.

WEFT COLOUR SELECTOR alarms

6144 Generic weft selector ERROR level 0

Meaning:
There’s been a level 0 internal error on the CSC board.

Remedies:
Replace the CSC board (table C-3). Once replaced, remember to carry out the self-learning
procedure (see Console manual).
Contact PROMATECH Customer Service.

6145 Pattern error

Meaning:
The system has detected that there are more than three colours at the same time in the
pattern.

Remedies:
Check the current pattern, especially if the colour management is incorporated in the Jacquard
pattern.

6146 Position error

Meaning:
The weft selector fingers move to suit the position of the loom. This alarm warns that the
Hall detectors on the weft colour selector have detected that the position of a finger isn’t
correct for the loom position.

Remedies:
Follow the remedy procedure described for alarm 6147.

6147 Overtemperature

Meaning:
The temperature of a weft colour selector coil is higher than 50°C. This generally happens
when too much current is used to move the finger.

Remedies:
Carry out the self-learning procedure (see Console manual).
Switch the loom off and check that when you move the fingers by hand, they move without
using excessive force, otherwise it means that there is a mechanical obstruction and so you
need to open the weft colour selector to find what’s impeding the movement of the finger.
Check the efficiency of the Hall detectors as follows:
switch the loom off, disconnect connector CT42 on the weft colour selector, remove the top
cover on the weft colour selector and switch the loom on again.
Enter in the weft colour selector technical parameters menu and enable the “sensor reading”
function. Again in the weft colour selector technical parameters menu, make a note of the
values of the finger position (mV) read on the Console (accepted range: 230 m V DC - 1200

Manually lower the fingers and then, with the fingers lowered, enable the “sensor reading”
function on the Console. Again in the weft colour selector technical parameters menu, make
a note of the values of the finger position (mV) read on the Console. Check that the values
of this second reading (fingers lowered) differ from those for the first reading (fingers raised)
by at least 3200 mV. If not, you’ll need to adjust the Hall detectors on the front of the weft
colour selector, or replace them.
Replace the CSC board (table C-3).
Check connection CT44 (also internally, if possible).
Check connections J03 and J04 on the CSC board.

6148 Internal alarm

Meaning:
This warns you that the CSC board has detected internal problems on the board thanks to
its internal diagnostics system.
Remedies:
Replace the CSC board (table C-3).

6149 Self-learning alarm

Meaning:
This tells you that no fingers have been detected during the self-learning procedure and
that therefore there are no fingers available for weaving.
Remedies:
Replace the CSC board (table C-3).
Check that the fingers move manually and freely when the loom is switched off.
Check connections CT42, CT43 and CT44 on the weft colour selector and connections
J03, J04, J05 and J06 on the CSC board (table C-3).
Disconnect connection CT44 and, with the loom on, check that 5 V DC between pins J and
K (from the side).
Carry out the Hall detectors efficiency test by following the procedure described for alarm
6147.

6150 Unacceptable colour selection

Not used.

6151 Colour not received

Meaning:
From 0° - 100°, the CSC board should receive the data for the finger to be moved at about
300°. This alarm warns that no data have been received.
Remedies:
Check the CAN-BUS connections on the CSC board (table C-3).
Replace the CSC board.
Replace the RTC board (table B-3). NB: Before replacing the board, you should save the
style data and shifts on the Memory Card or make a note of these, as all the data will be lost.

SHEDDING MACHINE alarms

8192 Generic shedding machine ERROR level 0

Meaning:
There’s been a level 0 internal error on the dobby board.

Remedies:
Replace the dobby board.
Contact PROMATECH Customer Service.

8193 Fatal error

Meaning:
The electronic dobby board hasn’t completed its initialising procedure that’s always done
when the control box is switched on.
This error may be due to a fault in the microprocessor or any of the electronic components
welded directly on the electronic board; in either case, the alarm will persist and cannot be
reset in any way.
This error may also be caused by an interruption in the program used for the initialising
procedure, in which case the error may disappear or only appear occasionally.

Remedies:
Switch the loom off, wait at least five seconds and then switch it back on again, thus giving
the loom and the dobby time to shut down completely and delete all anomalies. Then move
the loom and check whether the problem reappears.
Replace the electronic dobby board.

8194 Initialising

Meaning:
As for error 8193.

8195 Serious CAN error

Meaning:
This message warns of serious problems with the CAN-BUS line.

Remedies:
Switch the loom off, wait at least five seconds and then switch it back on again, thus giving
the loom and the dobby time to shut down completely and delete all electronic anomalies.
Then move the loom and check whether the problem reappears.
If the problem immediately reappears, replace the electronic dobby board.
Carry out the CAN-BUS cabling control procedure described in table “I”.
If a FIMTEXTILE dobby (with EUTRON dobby board only), check that there’s jumper JP1. If
it is, try extracting it and then returning it a few times to clean the contact and check that it
only enters after applying a little force (if this isn’t so, try tightening the slides with a pair of
pliers).

121 01 - 06 - 2005
 ALARM AND TROUBLESHOOTING MANUAL
LIST OF ALARMS

8196 Electromagnets error

Meaning:
This error, when active, includes three different diagnostics board outputs:
electromagnet overcurrent
electromagnet short-circuit or short-circuit towards earth
faulty or short-circuited onboard dobby board piloting mosfet.

Remedies:
Check that there are no signs of scratching on the insulation of each dobby connector at the
edges (e.g. the areas of possible mechanical rubbing or between two adjacent conductors
if stripped or interrupted); check the general cabling.
Check that the electromagnet isn’t short-circuited (totally or partially) and replace it, if
necessary.
Check on the dobby board that none of the piloting mosfets are short-circuited, thus tripping
this warning. This error will persist and cannot be reset in any way unless you replace the
electronic dobby board.
Given its type, the error should disappear completely after replacing the electronic board.

8197 No electromagnet power supply

Meaning:
The rating electronics on the dobby board hasn’t received the right voltage for correct piloting
of the electromagnets.

Remedies:
Check the power supply rating for the dobby board: this should be between +40 V DC and
+75 V DC (in the case of a FIMTEXTILE dobby) and 24 V DC (in the case of STÄUBLI). If
unsuitable, there could be an absorption problem.
If so, switch the loom off immediately, disconnect the power supply wires from the dobby
board and check the voltage coming from the loom without the dobby board connected and
especially at pin 1 (50 V DC) and pin 3 (0 V DC) on M8 on the VX032 board (table D-6).
If the rating is still out of range, it’s probably a problem coming from the loom; if the rating
returns within the accepted range, it’s probably a problem with the electronic board.
Check the status of the two fuses on the electromagnets power supply line (on the lower
electronic board); if open, replace with other identical fuses (F4A 250 V AC).
If OK, make sure that the fuse holders secure the fuses properly, especially on older boards.
Check the status of the two electromagnets power supply relays on the lower electronic
board): during NORMAL functioning the relays should be excited and the contacts should
be closed (+50 V DC should reach the piloting mosfet); if faulty replace the electronic dobby
board.

8198 No BRD power supply

Meaning:
There’s been a drop in the power supply fed to the dobby and coming from the loom (less
than the min 35 V DC).

Remedies:
Switch the loom off, wait at least five seconds and then switch it back on again, thus giving

122 01 - 06 - 2005
 ALARM AND TROUBLESHOOTING MANUAL
LIST OF ALARMS

the loom and the dobby time to shut down completely and delete all anomalies.
If the problem persists, measure the power supply with the loom at a standstill: it should be
about 50 V DC (usually 48 - 55 V DC). Make sure that the consumption level increases and
the voltage drops during electromagnet piloting (easily checked during pick-finding). Here
too, the level should not drop below the minimum.
If there are power supply rating problems, try replacing the electronic dobby board to check
for possible abnormal consumption downstream.
If the problem persists, contact the loom supplier. In fact, it may be that there isn’t enough
energy upstream at pin 1(50 V DC) and pin 3 (0 V DC) on M8 on the VX032 board (table D-
6).
This might happen after a fault in the 50 V DC power supply: upon receiving the rating
request from the dobby, the voltage “slumps” (drops).

8199 Emergency

If a FIMTEXTILE dobby

Meaning:
One or more magnets are partially short-circuited.

Remedies:
Check that the space around the electromagnet pack and between the various
electromagnets is free; eliminate any ferrous deposits or dirt using a cloth. Use compressed
air to clean the spaces between the electromagnets.
Check that the plastic cover on the electromagnet coil is not perforated or dented (outwards);
if in doubt, replace the electromagnet.
Check that there are no signs of scratching on the insulation of each connector at the edges
(e.g. the areas of possible mechanical rubbing or between two adjacent conductors if stripped
or interrupted).
Check the general cabling.

If a STÄUBLI dobby
Meaning:
The diagnostics in the dobby board has detected a fault on the board.

Remedies:
Replace the dobby board.

8200 FLA/FLB error

If a FIMTEXTILE dobby
Meaning:
The two proximity sensor signals are inverted when they reach the dobby board.
One or both of the proximity sensors are not sending the signal to the electronic board at
the right time.

Remedies:
In the first case, check that the proximity sensors are connected correctly; sensor FLA (i.e.
the first that meets the flag during its rotation in the correct direction) is always the one

123 01 - 06 - 2005
 ALARM AND TROUBLESHOOTING MANUAL
LIST OF ALARMS

nearest to the sabre levers and therefore the loom (looking at the dobby from side opposite
the loom).
If incorrect, invert the male/female connectors inside the dobby.
Or, directly on the terminal board of the electronic board, invert the outputs (the two black
wires) for the two cables 3X0.35 to which the sensors are connected (only during start-up).
If not, check that the power supply rating towards the proximity sensors (the two brown
wires) is +15 V DC.
Check that the yellow dobby leds on the sensor come on with the flag, as this means that
the sensor is correctly fed and that the distance (between 0 and 1.5 mm) is correct.
Check also that the output of the sensors (the two black wires) returns to the electronic
board and that the wires aren’t interrupted. If in doubt, replace both the proximity sensors.
If the problem immediately reappears, replace the electronic dobby board.

If a STÄUBLI dobby
Meaning:
The two proximity sensor signals are inverted when they reach the dobby board.
One or both of the proximity sensors are not sending the signal to the JDB electronic board
at the right time.

Remedies:
Check the cabling of the dobby proximities.
Check that the dobby proximities are properly.
Replace the dobby proximities.
Replace the dobby board.

8201 Pattern error

Meaning:
The dobby board hasn’t received the raised heald data from the loom when expected.
This alarm is generated when the loom fails to send the required data for the selection of
the next raising at the encoder 0° or if this data is not received by the dobby at 157° (input
sensor FLB).
The loom is stopped in both cases.
The alarm may also be generated when the CAN-BUS line doesn’t receive the pick signal.

Remedies if a FIMTEXTILE dobby:

Check the efficiency of proximity sensor FLB; if in doubt, replace the sensor.
Check the cabling of proximity sensor FLB from the electronic dobby board (internal/external)
up to the sensor. Carry out the full test sequence as for error 8200.
Check (with the loom moving) that proximity sensor FLB is excited at 157° dobby.
Check the cabling of the CAN-BUS connections on the onboard dobby board connector. It
may be that one or both of the CAN-BUS wires are disconnected or open (in this case other
warnings might appear with this alarm); if in doubt, redo the cabling.
Replace the electronic dobby board.
If the problem persists, replace the entire power supply + CAN-BUS cable between the
loom and the FIM dobby (normally supplied by others).
Carry out the CAN-BUS cabling control procedure described in table “I”.

Remedies if a Stäubli dobby:

Carry out the full test sequence as for error 8200.
Check the cabling of the CAN-BUS connections on the onboard dobby board connector. It

124 01 - 06 - 2005
 ALARM AND TROUBLESHOOTING MANUAL
LIST OF ALARMS

may be that one or both of the CAN-BUS wires are disconnected or open (in this case other
warnings might appear with this alarm); if in doubt, redo the cabling.
Replace the electronic dobby board.
Carry out the CAN-BUS cabling control procedure described in table “I”.

8202 Electromagnets error

If a FIMTEXTILE dobby
Meaning:
This warns you that one or more electromagnet connections are open or not perfectly in
contact.

Remedies:
Check the resistance of the electromagnets: this should be between 71 and 72.5 ohm
immediately after starting the dobby and 72.5 and 80.2 ohm when the dobby is hot (i.e. after
about 5-6 hours of uninterrupted working); if in doubt about the value of the resistance,
replace the electromagnet.
Check the status of the connections on the electromagnet connector on the dobby board.
NB: the electromagnet resistance control only happens when you switch the loom on and
not during NORMAL functioning; in which case, any anomalies due to an interruption or
false contact will only be detected at the next loom start-up.
If the problem immediately reappears, replace the electronic dobby board.

If a STÄUBLI dobby
Meaning:
This warns you that one or more electromagnets are open or short-circuited.

Remedies:
Check the resistance of the electromagnets: this should be between 200 ohm immediately
after starting the dobby and 300 ohm when the dobby is hot (i.e. after about 5-6 hours of
uninterrupted working); if in doubt about the value of the resistance, replace the
electromagnet.
Check the status of the connections on the electromagnet connector on the dobby board.
If the problem persists, replace the electronic dobby board.

8203 No oil/Level switch faulty

If a FIMTEXTILE dobby
Meaning:
This error is inactive during the first three minutes of using the dobby; when active, it groups
two different diagnostics board outputs:
case 1 - No oil circuit pressure
case 2 - Oil level sensor faulty.

Remedies:
Case 1
If this warning happens when the machine has been running for at least three minutes, it
means that there isn’t enough oil: the oil level sensor contact does not stay closed, but

125 01 - 06 - 2005
 ALARM AND TROUBLESHOOTING MANUAL
LIST OF ALARMS

opens for more than a minute at a time.

In this case, check that the warning isn’t due to a lack of oil in the tank or a blocked oil filter
or pipes.
If there’s oil in the tank, check that it flows correctly from the pipe overflow.
Use a tester to check the efficiency of the oil level sensor; if in doubt, replace the oil level
sensor (the contact closes when the oil level rises).
Case 2
If this warning happens when the machine has been stopped for at least three minutes, it
means that the oil level sensor is faulty: the oil level sensor contact stays closed even when
the machine is stopped.
Check that the oil flows from the overflow hole in the oil tank (continual dribble).
Use a tester to find the faulty internal contact and then replace the oil level sensor with a
new one.
It may happen that if the temperature is extremely cold, the oil (being very thick) finds it
difficult to flow through the hole in the tank: you need to widen the hole slightly to avoid this
problem.

If a STÄUBLI dobby
Meaning:
This error is inactive during the first two minutes of using the dobby; when active, it indicates
the opening of the oil level switch and therefore that there isn’t enough oil for correct
lubrication.

Remedies:
In this case, check that the warning isn’t due to a lack of oil in the tank or a blocked oil filter
or pipes.
Use a tester to check the efficiency of the oil level sensor; if in doubt, replace the oil level
sensor (the contact closes when the oil level rises).

8204 CAN-BUS error

Meaning:
This warns of an error on the CAN-BUS transmission line.

Remedies:
Switch the loom off, wait at least five seconds and then switch it back on again, thus giving
the loom and the dobby time to shut down completely and delete all anomalies. Then move
the loom.
Check the connection of the CAN-BUS cable on the electronic dobby board; if in doubt,
redo the connection cabling.
Check the state of the CAN-BUS cable between the loom and dobby board using a tester
and check that there’s +2.5 V DC on the CAN_H and CAN_L lines.
You can check this when the machine is stopped or running.
Always check for 60 ohm between CAN_H and CAN_L; if you find a different value (120
ohm) carry out the CAN-BUS cabling control procedure described in table “I”.
Replace the dobby board.

8205 Unauthorised movement

Meaning:
The dobby has detected abnormal movement of the loom or any movement not in line with
the dobby data.

126 01 - 06 - 2005
 ALARM AND TROUBLESHOOTING MANUAL
LIST OF ALARMS

Remedies:
Switch the loom off, wait at least five seconds and then switch it back on again, thus giving
the loom and the dobby time to shut down completely and delete all anomalies. Then move
the loom.
Check that the position in degrees of the loom matches movement when this occurs.

8206 Pick counter datum not received

Meaning:
The dobby hasn’t received the progressive pick number (Pick Counter) sent by the loom at
each turn (at each passing of the encoder 0°).

Remedies:
Switch the loom off, wait at least five seconds and then switch it back on again, thus giving
the loom and the dobby time to shut down completely and delete all anomalies. Then move
the loom.
Replace the dobby board.
Replace the RTC board (table B-3).
Replace the dobby board.

8207 Wrong pick counter sequence

Meaning:
The dobby finds a problem with the progressive pick number (Pick Counter) sent by the
loom after each turn.
The progressive number of the pattern sequence is also sent by the loom after each turn.

Remedies:
Switch the loom off, wait at least five seconds and then switch it back on again, thus giving
the loom and the dobby time to shut down completely and delete all anomalies. Then move
the loom.
Replace the RTC board (table B-3).
Replace the dobby board.

8208 Oil lubrication error

Only if a Stäubli dobby

Meaning:
This indicates that the contact in the oil level switch on the dobby is still closed despite the
fact that the loom has been at a standstill for more than a minute: it assumes, therefore, that
the level switch is faulty (permanently closed).

Remedies:
Check that there aren’t any deposits of oil around the level switch.
Check the dobby level switch and replace if necessary.
Replace the dobby board.

8209 Heald configuration error

Only if a Stäubli dobby

Meaning:
Inside the dobby board there’s a circuit that checks that the number of the magnets fitted is
compatible with the configuration on the dobby board. This alarm warns you that the fitted
dobby board isn’t configured for the number of the magnets actually fitted on the dobby.
This alarm will occur when you replace the dobby board if you fit one with the wrong
configuration.

Remedies:
Replace the dobby board.
Contact the dobby manufacturer to get the board set up correctly.

8448 Generic shedding machine ERROR level 1

Meaning:
There’s been a level 1 internal error on the dobby board.

Remedies:
Replace the dobby board.
Contact PROMATECH Customer Service.

8449 Loom/Jacquard out of synch

Meaning:
The RTC receives the pick number at each pick from the Jacquard; a coherence check
takes place within the RTC. In other words, the system checks that the Jacquard has sent
the picks in the right order and without skipping any.

Remedies:
This alarm may occur when you load a pattern while the rapiers are still in the shed; in this
case, you should take the loom to about 340 degrees and then reassign the pattern.
Replace the IJD board (table C-4).
If the alarm persists, replace the RTC board (table B-3).
Contact the Jacquard machine manufacturer.

11269 Motor 1 temperature alarm

Meaning:
The temperature of the coils in the tuck-in device 1 (RH) is higher than 55°C: this generally
happens when too much current is used to move the device.

Remedies:
Carry out the levelling calibration operation for distance A and B of the device (see Console
manual).
Switch the loom off and check that when you move it by hand, the tuck-in device moves
without using excessive force, otherwise it means that there is a mechanical obstruction
and so you need to open the device to find out what’s obstructing the movement.
Check the efficiency of the Hall detector as follows:
Switch the loom off, disconnect connector J05 on the tuck-in device and switch the loom on
again.
Manually move the device and check (in the tuck-in device menu) that the value of the Hall
detector when the device fully left is about 0.7 V DC, while when fully right it’s about 4.7 V
DC. If this isn’t so, replace the tuck-in device or replace the ISC board (table C-2).

Remedies:
This isn’t an alarm, but only a warning.
To reset, switch the pre-feeder in alarm mode off and then back on again.
NB: after doing this, you need to reset the movement mechanically for the pre-feeder spare
spool.

15362 No end at entrance to weft feeder

Meaning - LGL pre-feeder:

The pre-feeder hasn’t been able to wind the spare coil of weft within the max time (15
seconds).

Remedies - LGL pre-feeder:

Try to load the spare weft again, holding the thread near the winding spool to make it easier.
Check for any problems with the fuses in the power supply box.
Manually turn the flywheel to check that the motor shaft turns freely.
Check the settings in the STRAP table and in the Finger number/Pre-feeder number
association table.

 ALARM AND TROUBLESHOOTING MANUAL
LIST OF ALARMS

16395 I2t at motor

Meaning:
The thermal protection calculated by the cutter motor drive has tripped. The motor is being
used above the max limit. The drive is efficient.

Remedies:
Check that the motor shaft turns freely: bear in mind that there’s a brake in the motor that
tends to brake the motor when the loom is switched off and so should never be completely
free nor completely blocked.
Check that the blades aren’t caught or that there’s anything preventing the free rotation of
the cams.
Check that there’s 24 V DC at terminals 1 and 5 on terminal board XA03 in the main control
box when the loom is moving; otherwise replace the HCBS board (table C-12).

 ALARM AND TROUBLESHOOTING MANUAL
LIST OF ALARMS

16399 Max exceeded space error

Meaning:
The cutter motor works with space tracking of the loom encoder. If the space error between
the loom encoder and the motor encoder is higher than the max calculated value (15°
loom), the drive stops and generates this error. In other words, the cutter motor isn’t in time
with the loom movement and therefore has accumulated a delay of 15°.

Remedies:
Check that the motor shaft turns freely: bear in mind that there’s a brake in the motor that
tends to brake the motor when the loom is switched off and so it should never be completely
free nor completely blocked.
Check that there are no problems with the mechanical parts (toothed wheels, arms,
blades,.....).
Check that there’s 24 V DC at terminals 1 and 5 on terminal board XA03 in the main control
box when the loom is moving; otherwise replace the HCBS board (table C-12).

The RTC is the main loom board that controls and manages all the signals coming from the
machine.

Replacing instructions:
Check that the loom is switched off.
Before doing anything else, you need to save all the loom data on a Memory Card or make a note
of them so that you can enter them again after replacing the board.
After replacing the board you can then load all the style data.
See the Console user manual (“Memory Card” section) for details.

The RTC board is at the top of the control box, so the first thing to do is to open the top door.
The RTC board has various slots with other boards fitted in these vertically.
Remove the two support columns for the vertical boards.
Remove the support and extract all the boards (VX044, VX035, FFM and blower for the 2003
system; IJD, CWS, BCS for the 2004 system).
Slide out the connectors by the board, at the rear of the RTC (X169, X170, X173, X172).

CAN-BUS cabling control procedure

Switch the loom off.
Disconnect cable WCS18/1 on connection X826 on the SDI board and insert the multimeter pins
(in ohm mode) at pins 3 and 4 (white and brown wire). The value of resistance should be 120 ohm
+-10%, meaning that the CAN-BUS circuit in the RH side of the loom is correctly connected.
If this isn’t so, check all the connections indicated on the RH side of the loom (on the CDB board,
on the drives, etc.).
Disconnect cable WCS22/2 on connection X811 on the SDI board and insert the multimeter pins
(in ohm mode) at pins 3 and 4 (white and brown wire). The value of resistance should be 120 ohm
+-10%, meaning that the CAN-BUS circuit in the LH side of the loom is correctly connected.
If this isn’t so, check all the connections indicated on the LH side of the loom (on the JDB board, on
the ISC board, on the CSC board, etc.).
