Attention: Important for RS compressors
Risk of electric shock from charged capacitors!
Always disconnect the system from the power supply
and then wait a further 10 minutes before touching
electrical components. The power capacitors take this
time to discharge.
Check the DC bus voltage at the system terminal strip
of the inverter by measuring between the +DC and -DC
terminals and the chassis. The exact position can be
found in the operating manual of the inverter, the
voltage must read zero for all three measurements.

1.3 Displaying / changing values
1.3.1 Selecting values
You can display values, e.g. total hours, and set the control
system, e.g.cut-in and cut-out times, in the sub-menu.
To reach the main menu, you must press the + keys
at the same time.
Use the or keys to switch between the following sub-
menus:
[MAINTENANCE SCHED.]
[CONTROL MENU]
[FAULT MEMORY]
[TIMER CONTROL]
[LIMIT VALUES]
[OPTIONAL IN-/OUTPUTS]
Enter a sub-menu by pressing the
key
.
Use the or keys to go to a menu item.
To exit the sub-menu, you must press the + keys at
the same time.
To exit the main menu, you must press the + keys at
the same time again.
1.3.2 Changing values
Enter the sub-menu and then the menu item containing the
value you wish to change.
Press the key, the value flashes. Press the or

1.5 Setting pressure
Compressor control/speed is achieved using a pressure
transducer signal to the controller and/or inverter PID to
match output to system demand.
In the [CONTROL MENU] menu you have to set the
maximum pressure CUT-OUT POINT and the minimum
pressure CUT-IN POINT or TARGET PRESSURE.
In the range between the CUT-IN POINT or TARGET
PRESSURE and CUT-OUT POINT the output or speed of
the compressor is controlled or regulated to match the
compressed air requirement.
Example:
CUT-OUT POINT 8.5 bar (123 psi)
CUT-IN POINT (SS) 7.5 bar (109 psi)
TARGET PRESSURE (RS) 8.0 bar (116 psi)

1.0 Operator Controls
CC1092267A 7
The output of the compressor is controlled between
these points or speed is regulated so that the set
pressure of 8.0 bar (116 psi) is maintained.
When pressure reaches the CUT-OUT POINT of 8.5
bar (123 psi), the compressor switches to off-load.
If pressure falls to the CUT-IN POINT of 7.5 bar (109
psi), the compressor is switched back into on-load.
Maximum pressure is set in the [CONTROL MENU]-
sub-menu. The + keys have to be pressed at the
same time. You are then taken to the main menu. Use
the key to switch to the [CONTROL MENU] sub-
menu, then press the key.
The CUT-OUT POINT menu item now appears on the
display. Pressing the key causes the value to flash.
Increase or decrease this value using the or
keys, confirm the value set by pressing the key.
Note
The controller checks that the value set can be used.
The maximum pressure CUT-OUT POINT must be at
least 0.2 bar more than the CUT-IN POINT or TARGET
PRESSURE.
You may therefore have to set the minimum pressure
first. To keep the number of stop/starts to a minimum,
the difference between the CUT-OUT POINT and CUT-
IN POINT or TARGET PRESSURE should not be too
small.
Minimum pressure is set in the [CONTROL MENU]
sub-menu press the key to go to the CUT-IN POINT
or TARGET PRESSURE menu item.
Pressing the key causes the value to flash.
You can increase or decrease this value using the
or key, confirm the value set by pressing the key.

2.1 Starting the unit
Caution
If the unit is ready, i.e. the green LED is flashing, the
compressor may automatically start at any time.
Use the isolator to switch the unit on.
If warning or fault messages appear in the third row of the
display, these first have to be rectified and confirmed
using the key.
Then start the unit by pressing the key on the
HYDROVANE Pro.
2.2 Emergency stop button
The EMERGENCY stop button is located below the
HYDROVANE Pro. Only use the emergency stop button
to shut down the unit in real emergencies. When shutting
down normally, always use the key.
2.3 Switching off the unit
The unit is switched off by pressing the key on the
HYDROVANE Pro. However the unit will only stop after a
2-second soft-stop.
The soft-stop is preset to protect the compressor.
2.4 On-load/off-load
Descriptions of the CONTINUOUS OPERATION and
AUTOMATIC OPERATION modes can be found in
section 3.1.1.
OFF-LOAD:
If there is no pressure requirement from the system with
the unit in CONTINUOUS OPERATION, it switches to
OFF-LOAD. This means that the motor and compressor
run but no air is delivered into the system.
The unit behaves differently in AUTOMATIC OPERATION
mode. If there is no pressure requirement, the compressor
switches to OFF-LOAD. The unit is switched off after a run-
on time that is shown on the display. If there is another
pressure requirement during the run-on time, the unit is
automatically switched on.
ON-LOAD:
If the unit is in ON-LOAD, air is delivered into the system.
2.5 Warning/fault messages
Warning and fault messages are shown in the third row of
the display. The red light signal flashes at the same time.
A table containing messages and suggestions for how to
remedy them is in Section 4.5.
2.5.1 Warning messages
If there are warnings, the red light signal flashes slowly.
The unit does not automatically shut down when there
are warnings. However ignored warnings may cause
faults.
Rectify what is causing the warning and press the key
to cancel the warning.
2.5.2 Fault messages
Fault messages result in the unit automatically shutting
down or do not permit the unit to be started.
Once you have rectified the problem, you must confirm
by pressing the key.

2.0 Operating & Maintenance
10 CC1092267A
2.6 Maintenance
Maintenance intervals are preset when the compressor is
supplied, more information is available in the unit's user
handbook.
It may be necessary to adjust maintenance intervals to
suit ambient conditions. For example, the air filter‘s level
of contamination depends on the compressor's intake
conditions.
The HYDROVANE Pro allows the operator to program
various maintenance intervals (see section 2.7).
If there is a maintenance interval at +200h (hours), the
compressor is not automatically shut down. The
MAINTENANCE DUE message appears on the display.
If you want the compressor to automatically shut down
when a maintenance interval is due, you have to set this
function.
Go to the [MAINTENANCE SCHED.] sub-menu. Go to
the last SHUTDOWN OFF menu item, press the key.
The OFF value starts to flash. By pressing the key you
can change the value to ON, confirm by pressing the
key.
The compressor now automatically shuts down when the
-100h maintenance interval is displayed.
Once maintenance is complete the interval should be
reprogrammed back to 2000h. Confirm the maintenance
message using the key.
2.7 Programming maintenance intervals
To program a maintenance interval, go to the
[MAINTENANCE SCHED.] sub-menu. Here you can
program the maintenance intervals for:
AIR FILTER IN 2000h
OIL FILTER IN 2000h
SEPARATOR IN 4000h
OIL CHANGE IN 4000h
Go to the menu item required and press the key, the
value then starts to flash. Use the or key to set the
value to an interval of 0….9999, confirm your entry with
the key.
If you do not want the maintenance intervals to be
monitored, program the intervals to more than 9999
hours in the various menu items. ---- appears on the
display. The maintenance interval is then blocked.
Note
Values shown are examples only, those used in your unit
may be different.
2.8 Total/load hours counter
Press the + keys at the same time to reach the
main menu. Press the key, you are now in the
[MAINTENANCE SCHED.] sub-menu. Use the or
keys to go to the various menu items.
The total hours counter states the time for which your unit
has been in on-load and off-load.
The load hours counter states the time for which your unit
has been in on-load.
Note
The total and load hours are lost if the HYDROVANE Pro
is replaced.

3.1 [CONTROL MENU] sub-menu
The most important parameters of the [CONTROL
MENU] menu have already been explained in Section
1.5 Operator Controls. This section simply contains an
overview and explanation of additional functions.
3.1.1 Operating modes
Go to the [CONTROL MENU] sub-menu, use the key
to go to the AUTOMATIC OPERATION menu item.
Press the key, AUTOMATIC OPERATION starts to
flash. Use the key to switch to CONTINUOUS
OPERATION, confirm selection by pressing the key.
You can choose from two operating modes:
AUTOMATIC OPERATION is the most economical of
your compressor's operating modes. If there is no
system demand, the compressor is shut down after the
RUN-ON TIME. The control system automatically
recognises when compressed air is needed again. The
unit then starts up straight away.
CONTINUOUS OPERATION is only needed for some
special applications. When in this operating mode, the
motor is not shut down if there is no system demand.
The compressor runs continually in off-load mode when
there is no pressure requirement.
3.1.2 Second pressure range (p
2
)
The difference between the maximum and minimum
pressure is called the pressure range. The second
pressure range function allows you to use another
pressure range in addition to the pressure range
already set (see Section 1.5). This could be used for
example to implement night-time running at lower
pressures.
The settings for the second pressure range function are
in the [CONTROL MENU] sub-menu. Menu items are:
p

may be different.
3.1.5 Automatic re-start
Caution
In this operating mode, the compressor may start
automatically at any time and after an unlimited length
of power loss.
Always fit the compressor with warning signs, lock the
room containing the compressor and instruct your
staff.
Fit the isolator specified by EN60204 and fit the
appropriate warning signs on it.
After a power loss that has not exceeded the preset time,
the unit can re-start automatically.
The settings needed must be undertaken in the [CONTROL
MENU] sub-menu. Menu items are:
AUTO RESTART OFF
POWER LOSS TIME Xs
START-UP DELAY Xs
Use the AUTO RESTART ON menu item to activate the
automatic re-start.
You can state the time for which a power loss may last and
after which the compressor is to automatically re-start in
the POWER LOSS TIME menu item. The time can be set
within a period of 2 - 999 seconds. If the power loss lasts
longer than the time you have set, the unit does not
automatically re-start. The POWER LOSS. fault message
then appears on the display

3.0 Additional Functions
12 CC1092267A
You can also program a start-up delay of 1 – 60 seconds.
This is set in the START-UP DELAY menu item and
ensures a staggered start-up if the installation features
several compressors. This ensures that the power supply
is not loaded unnecessarily.
3.1.6 Unlimited autom. re-start after
power loss
The control system can perform an automatic re-start
after any power loss period.
You must read and apply the following safety notices
before setting unlimited automatic re-start.
Caution
In this operating mode, the compressor may start
automatically at any time and after an unlimited
length of power loss.
Check the safety notices (e.g. EN1012-1, EN60204)
that apply in your country to find out whether you
can run an unlimited autom. re-start and what
safety precautions must be taken.
Always fit the compressor with warning signs, lock
the room containing the compressor and instruct
your staff.
Fit the isolator specified by EN60204 and fit the
appropriate warning signs on it.
To set unlimited automatic restart, proceed as follows:
1. Press the key for 5 seconds.
2. Use the or keys to enter code 8888.
3. Press the key to transfer the set code
The menu item for the max. power loss time can also
be programmed to [POWER LOSS TIME –s]. This is
the setting for an unlimited automatic re-start.
If you re-enter the code, you cancel the function.
Note
Details for locking sub menus by code can be found in
Section 3.6
3.2 [FAULT MEMORY]sub-menu
Warning messages and faults are stored in the fault
memory. The last warning message or fault recorded is
always at the top. In order to distinguish between faults
and warning messages, faults are marked with an
exclamation mark !.
Use the or key to switch between the individual
memory areas in the fault memory.
The faults are displayed as follows:
03! EM-STOP 000100h
a) b) c) d)
a) The same fault has occurred three times.
b) This relates to a fault.
c) Fault has occurred due to the emergency stop button
being pressed.
d) Fault occurred at 100 running hours.
03 HIGH TEMP 000100h
a) b) c)
a) The same warning has occurred three times.
b) Warning resulting from compressor temperature being
too high
c) Warning occurred at 100 running hours.
The last eight warning messages or faults recorded are
displayed in the fault memory. All messages and faults
occurring before that are retained in the long-term memory.
The frequency with which a warning or fault occurs is
therefore always recorded.
You can access more detailed information on warning
messages and faults that have been recorded in the fault
memory. The following are saved for every warning
message/fault recorded:
- time and date
- compressor status (e.g. on-load)
- speed (RS)
- compressor temperature and pressure
When accessed, these values flash to clearly show that
they are not the current display values.
Use the or
key to go to the warning or fault message
of interest. Press the key, day of the week, date and
accurate time are now displayed (flashing) in the first row.
Press the key again, the status of the warning/fault of
the compressor is displayed (flashing) in the first row. If the
key is pressed again, the compressor temperature and
pressure are displayed (flashing) in the first display row.

3.8.3 On-load/off-load remote control
The HYDROVANE Pro control system allows the
operator to switch the compressor into on-load or off-
load from a remote point through the connection of two
potential-free contacts. This function is needed when
using an external control for example.
Go to the [OPTIONAL IN-/OUTPUTS] menu where you
must program one input with the ENAB.REM.LOAD
function and another with the REMOTE LOAD function.
The unit can now be switched to on-load or off-load
using these two inputs.
In the circuit diagram (Fig. 5) we have assigned inputs
as follows:
INPUT 1:ENAB.REM.LOAD
INPUT 2:REMOTE LOAD
You can of course program the inputs any way you
choose.
If input 1 is activated, the unit can only be switched into on-
load or off-load by remote control. Both pressure ranges
and time control mode are interrupted (decoupled). If input
2 is now activated, the compressor is in on-load. If input 2
is not activated, the compressor is in off-load.
If the supply pressure exceeds the preset operating
pressure of 0.5 bar (7 psi), the WARNING LINE PRESS
indication appears on the display. Remote control is
deactivated at the same time. The unit now runs again
using one of the preset pressure ranges until the
WARNING LINE PRESS is acknowledged.

3.8.5 Remote start / stop
This function allows the operator to externally switch the
compressor on and off. You have two ways of
implementing this function. The remote start / stop
function is permanently programmed, this relates to
terminals X10 and X12 (see circuit diagrams).
The unit continues to run while the potential-free contact
is closed. If the contact is opened, the soft-stop is
undertaken and the unit stops.
Note
The unit is controlled using the remote start / stop
function. If the unit is shut down during operations, e.g.
due to power loss, it does not automatically start up when
the power is restored. The potential-free contact must
first be re-opened and then closed to restart the unit.
1st option
The compressor is to be activated using a potential-free
contact.
Activate this function in the [CONTROL MENU] sub-
menu. Go to the ENABLE REMOTE-START menu item.
Once you have pressed the key, the OFF value starts
to flash. You can now use the key to change the value
to ON. The symbol appears in the first display row.
Connect the potential-free contact that you need for the
remote start / stop function to the X10 and X12 terminals
(see circuit diagram). This input is permanently
programmed for the remote start / stop function.
If the remote start / stop function is activated, you can no
longer control the compressor using the and keys.
Only the emergency stop button remains activated. The
compressor can now only be switched on and off using
the potential-free contact.
2nd option
A control room is to decide whether the enable for the
remote start / stop function is issued. The function for the
enable is implemented using a digital input. If the enable
is issued, the compressor can only be switched on and
off using the external potential-free contacts (X10 and
X12). If the enable is not issued, the compressor can only
be switched on and off on the HYDROVANE Pro.
Connect the potential-free contact for the remote start /
stop function to the permanently programmed X10 and
X12 terminals.
In the [OPTIONAL IN-/OUTPUTS] menu you now have to
program one input with the ENAB.REM-START function
(see Section 3.5.1).
The symbol appears in the first display row. In the
[CONTROL MENU] sub-menu behind the ENABLE
REMOTE-START menu item, EXT. appears.
If the input is closed, the unit can only be switched on
and off using the potential-free contact.
If the input is opened, the unit can only be switched on
and off using the HYDROVANE Pro.
