1.1 About this manual
This manual contains information relating to both Fixed
Speed and Regulated Speed models. Throughout this
manual, where a section relates exclusively to one or
the other model, the symbol (Fixed Speed) and
(Regulated Speed) are used respectively to indicate
their relevance.
Any values shown in screen shots are for illustrative
purposes only. They are not specific values for your
particular model of compressor.
At various stages throughout this manual, references
will be made to finding individual menu items. These
references are shown in the following format: Display
screen tab > Next menu level > [next menu
level ...etc.] > menu item.
The information given in this manual was correct at the
time of printing. However, based on Gardner Denver’s
policy of continuous product improvement, we reserve
the right to make modifications or changes without
notice.
This manual is valid from software version
DXL-DH(RS)-1.xx.
1.2 Selection and Qualification Of
Personnel; Basic Responsibilities
Work on/with the machine must be carried out by
reliable personnel only. Statutory minimum age limits
must be observed.
Employ only trained or instructed personnel. Clearly set
out the individual responsibilities of the personnel for
operation, set-up, maintenance and repair.
Ensure that only authorized personnel work on or with
the machine.
Define the machine operator's responsibilities, giving
the operator the authority to refuse instructions by third
persons that are contrary to safety regulations.
Do not allow persons to be trained or instructed or
persons taking part in a general training course to work
on or with the machine/unit without being permanently
supervised by an experienced person.
Work on the electrical equipment of the machine/unit
must be carried out only by a skilled electrician in

2 Safety
2.1 Electrical Warning
Danger
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 require this time to discharge.
Check the DC bus voltage at the system terminal
strip of the frequency converter by measuring this
between
1) the +DC and -DC terminals (the exact position
can be found in the operating manual supplied
for the frequency converter),
2) between the +DC terminal and the chassis, as
well as
3) between the -DC terminal and the chassis.
The voltage must read zero in all three
measurements.
2.2 Safety Guidelines
This operating manual exclusively describes the control
unit. It contains important references and warnings, and
therefore should be read by the relevant operator as
well as by the installer before installing and operating
the unit.
Note
Not only should the general safety references
mentioned in this “Safety guidelines” chapter be
observed, but also any special safety references
referred to in the other sections of the manual.
2.3 Safety Instructions
Gardner Denver is not liable for any damage or injury
resulting from the non-observance of these safety
instructions or negligence of the usual care and
attention required during handling, operation,
maintenance or repair, even if this is not explicitly
mentioned in these operating instructions. This applies
even where these operating instructions do not provide
specific indications in this regard.
If any of the regulations contained in these instructions
– especially with regard to safety – does not correspond
to the local legal provisions, the stricter of the two shall
prevail.
These safety regulations are general and valid for
various types of machines and equipment. It is
therefore possible that some references do not apply to
the unit(s) described in these instructions.

6 Setting the pressure bands
Danger
When the system is in stand-by mode, i.e. the green
LED is flashing, the compressor can start
automatically at any time.
6.1 About pressure bands
The range between the upper and lower pressure
settings is referred to as the pressure band.
Two pressure bands are available. These are called p1
and p2.
p1 is the normal (default) pressure band and is
used whenever p2 is not active.
p2 is an alternative pressure band that can be
activated if a different line pressure is required.
6.2 Regulated Speed Models
On VS models, software in the GD Pilot TS controller
varies the motor speed to exactly match the demand for
compressed air.
Due to the nature of the rotational speed control
software, there are two pressure settings:
the upper setting (p1 Cut-Out Point/p2 Cut-Out
Point) and
the lower setting (p1 Target Pressure/p2 Target
Pressure).
The lower pressure setting indicates the pressure which
should be kept constant in the distribution system.
The upper pressure setting is the figure at which the
compressor will have stopped delivering air and will go
off-load.
For example:
p1 Cut-Out Point: 10.0 bar
p1 Target Pressure: 9.5 bar
The rotational speed of the machine will vary between
minimum and maximum to maintain the p1 Target
Pressure of 9.5 bar.
If the line pressure reaches the upper pressure of
10.0 bar due to no or low air demand, the compressor
will go off-load and the run-on timer is activated.
6.3 Fixed Speed Models
On fixed rotational speed models, there are also two
pressure settings:
the upper setting (p1 Cut-Out Point/p2 Cut-Out
Point) and
the lower setting (p1 Cut-In Point/p2 Cut-In Point)
The lower pressure setting is the pressure at which the
compressor will go on-load.
The upper pressure setting is the figure at which the
compressor will go off-load.
For example:
p1 Cut-Out Point: 10.0 bar
p1 Cut-In Point: 9.5 bar
At the upper setting, the intake regulator valve within
the machine will close and the compressor will go off-
load, delivering no more air. The run-on timer will also
be started.
At the lower setting, the intake regulator valve will open
and the compressor will go back on-load, delivering full
output again.
6.4 Setting the p1 Pressure Band
Pressure is set in the Settings > Control menu.
1) Touch p1 Target Pressure or p1 Cut-In
Point .
2) Use the keypad which will appear to enter your
desired setting (the permissible pressure limits are
displayed on the keypad screen).
3) Confirm the entry by pressing OK.
The display will revert to the previous screen.
4) Touch p1-Cut-Out Point.
Note
The upper pressure setting must be at least 0.3 bar
higher than the lower pressure setting.
The controller checks whether the value set can be
used. To prevent excessive wear of your compressor,
the difference should preferably be no less than 0.5 bar.
5) Enter your required setting using the keypad.
6) Confirm the entry by pressing OK.
