Autoink User Guide
The Autoink system is a modern replacement for the Hydrair system to
automatically monitor and fill the ink ducts across the press.
The new design uses the existing Hydrair bars whilst replacing the control system
and solenoids. A Siemens PLC controls the system and a unit mounted HMI is
utilised to monitor duct levels and alarm messages to allow for more accurate and
quicker fault finding.
A warning sounder mounted in the quiet room alerts press crew to potential
problems.
Control Box
□ Each duct is locally fitted with a control box with one on/off switch per
duct.
Ultrasonic sensor:
□ Only one sensor is fitted to each duct. The sensor however is a more
accurate ultrasonic version which can control much lower duct levels
compared to the existing capacitive type sensor.
□ If duct levels are in a healthy state
pressing the green start button will
put the duct in auto mode.
□ A white indication LED is fitted into
the integrated Start/Stop button
□ When the duct is in auto mode the
LED is illuminated
□ When the duct is filling the LED
flashes.

□ To allow the system to operate with only one sensor the Autoink system is
connected to the press control system. As the system knows what
imposition is selected it will select Op, Drive or both valves accordingly.
□ For example if the unit is running a half web to the drive side, only the
drive side valve will operate. Indication of selected valves is provided on
the Pre-set screen on the HMI.
HMI (Human machine interface)
□ An HMI is fitted to the Operator side panel to allow viewing of duct levels,
fault messages as well as selection of manual fill mode and the resetting of
the alarm sounder.
□ One sensor is mounted in the
centre of each bar.
□ It is mounted flush with the bottom
of the bar to reduce possible
contamination.
□ If the sensor gets dirty the duct
will not go into auto mode and will
sound an alarm in the quiet room.
A message will also appear on the
HMI
□ Duct levels are pre-set and can not
be changed by operators.
□ Optimum duct level setting is (50%)
as shown on left.
□ This is to reduce waste and possible
contamination to the ink in the
duct.

Home page.
Main Page
□ The cylinders on A10 are red to
denote that the duct is not in
auto mode.
□ The box on the RHS of the
screen shows current alarms i.e.
A 10 duct not in auto mode
□ Pressing the o for each colour
take you to the duct level
screen.
Click the “continue” to home
page button to move to main
information screen.
□ The main information screen
shows a mimic of the unit. The
cylinders change colour to
identify if they are in automatic
mode
□ If the cylinder on the mimic are
green the duct in question is
healthy and in auto mode.

Duct Level Screen
□ Each level/colour on the tower has a duct level screen which provides a
graphical representation of current duct levels.
□ Links to other key screens are also provided as well as information on if the
duct is in auto mode.
Manual Override
□ As an overflow precaution the solenoid valves that fill the ducts only
operate when they receive a signal from the press to say that it is running.
□ To allow ducts to be filled manually, for example after duct cleaning a
manual override facility has been incorporated into the design.
□ As well as feedback on duct
levels indication is also provided
to show if the solenoids are
currently operating.
□ On the manual override screen
press the override button.
□ This will allow the ducts to be
filled manually via the green
start button on the junction
boxes.
□ Once the ducts reach a level of
20% they will automatically drop
into auto mode.
□ The override function times out
after 5 minutes.

Alarm Logs
□ To assist in fault finding a log of faults is recorded
Fault messages
□ If a duct is in fault mode the current alarm box and alarm log will provide a
list of faults.
Examples of faults include:
Duct level too low
Duct level too high
No feedback from Sensor
Duct not in Auto
Duct in manual fill mode
Press running and no attempt to fill duct
Too many requests to fill duct
Each message will display the duct in question and the faults, i.e.:
A10 Duct not in automatic
A10 duct – No feedback from sensor.
In the alarm log the date/time will also be recorded.
Warning Sounder
□ To warn press operators of any faults during the run, a sounder has been
fitted in the quiet room. This will sound if any duct drops out of auto
mode. The sounder can be silenced by pressing the “reset alarms” button
on the main page. At this point the duct then needs checking and putting
back into auto or the sounder will go off again after 5 minutes.
□ The alarm log records when and
what caused a fault for historical
fault finding purposes.

Spreader bar Taps
The taps on the spreader bar are set to optimum positions during commissioning.
They should not be altered. By opening up all valves to maximum it could result
in parts of the duct overflowing.
