4.1 Overview
4 Design and Function
4.1 Overview
The SAM 2 is used for the control, regulation and monitoring of stations comprising multiple com‐
pressors, blowers or vacuum machines in a commercial environment. SAM 2 reacts flexibly to fluc‐
tuating compressed air demand and thus reduces energy consumption. The system takes into ac‐
count machine run times and deployment priorities. Important parameters are clearly represented
as coloured graphic elements. The high-resolution touch screen enables user-friendly settings.
SAM 2 is offered as:
■ SAM 2-4
■ SAM 2-8
■ SAM 2-16
They differ in the number of controllable machines (see chapter 2 "Design variants and options").
Using the SBU , you can flexibly expand the number of interfaces.
SAM 2 comprises the following components:
■ The central pressure transducer measures the pressure in the air network and passes the val‐
ue to SAM 2 .
■ The processing unit of the SAM 2 decides according to default parameters, which machines
are switched to load to keep the pressure in the air main constant. All data are clearly graphi‐
cally represented. You can analyse and archive the data provided.
■ The display and control panel of the touch screen provides information on current pressure and
other parameter values and offers various possibilities for individual settings.
Compressors with SIGMA CONTROL and SIGMA CONTROL 2 as well as those with conventional
controllers can be linked to SAM 2 .

4.6 Operation and function
SAM 2 has been developed for a multitude of possible applications. Generally, most of the default
settings can be kept or have to be changed only slightly.
4.6.1 Adaptive 3D control
The adaptive 3D control minimises the energy requirements of the compressed air station by auto‐
matically adapting to the operating conditions.
It automatically adapts the selection of the machines to be activated and deactivated as well as the
cut-out and cut-in pressures for the selected machines to the current operating conditions of the
compressed air station.
■ Chapter 7.10 "Peripherals"
4.6.2 Base load sequencing
The controller will equally use machine of the same size. The standard for comparison is the num‐
ber of operating hours. The machine with the least number of operating hours is used the most.
4.6.3 Time control
The compressed air system can be operated via an integrated timer. There are 32 switching points
per week available.
4.6.4 Power limiting
If the power limiting function is activated, the system will add machines only to the point where the
overall load capacity of the running machines exceeds the specified power limit. The nominal pres‐
sure and the maximum speed are used for calculating the overall load capacity.
4.6.5 Air main charging
After the activation of the compressed air station, the air network is charged at the specified net‐
work charging speed.
4.6.6 EMERGENCY operation
A compressed air station can run in EMERGENCY operation if each machine has its own system
pressure switch or presser control system. This is always the case with KAESER rotary screw
compressors. Compressed air systems with rotary blowers or reciprocating compressors may or
may not have machines provided with their own system pressure switches. Stations with machines
without system pressure switches cannot operate in EMERGENCY mode. These compressed air
systems cannot deliver compressed air without SAM 2 .

4 Design and Function
4.6 Operation and function
Compressor stations with EMERGENCY mode (manual mode)
EMERGENCY mode can cause large pressure swings in the air main.
The connected machines are automatically switched to EMERGENCY mode:
■ When the voltage supply of SAM 2 fails in activated state
■ When the connection to the pressure transducer is interrupted
■ When SAM 2 itself fails
The machines then run under their internal pressure regulation, independent of SAM 2 . The ma‐
chines can be manually switched to EMERGENCY operation (manual mode) for test purposes.
Compressor stations without EMERGENCY mode (manual mode)
No compressed air is delivered without SAM 2 .
The output relays switch off:
■ When the voltage supply of SAM 2 fails
■ When the connection to the pressure transducer is interrupted
■ When SAM 2 itself fails
This causes the connected machines to switch to idle or off. The compressed air system no longer
delivers compressed air.
4.6.7 Visualisation at external devices
The user interface of SAM 2 can be represented at an external computer (PC, laptop, tablet). For
this purpose, SAM 2 must be connected to the external computer via the Gigabit Ethernet connec‐
tion X7, directly via a network cable or indirectly (network). A web browser is used for the visualisa‐
tion.

6.9 Planning the wiring
➤ Note the following when connecting the pressure transducer:
■ Connect the pressure transducer either to the side or the top of the air receiver so that no
condensate can settle.
■ If the pressure transducer is connected to the main collector pipe, fit a small, additional air
receiver (item 8 order separately, see chapter 13.6 for the material number).
■ Fit the pressure transducer downstream of the air treatment components because pres‐
sure losses caused by air treatment components or pipework can occur between the ma‐
chine and the point of measurement.
■ The airflow at the point of measurement must not pulsate.
■ Note the installation depth of the pressure transducer.
■ Install a shut-off valve between the air receiver and the pressure transducer. This allows
replacement of the pressure transducer without having to vent the air receiver. Ensure that
the shut-off valve cannot be closed during operation.
■ A kit of parts for the air connection is available separately (see chapter 13.6 for the materi‐
al number).
6.8.2 Electrical connection
Avoid signal distortion by uusingg suitable wiring and screening.
1.
Use two conductor screened cable with minimum section 0.75 mm2.
2. The pressure transducer must be earthed.
■ Earth by metallic contact with the air receiver or
■
Use a separate equipotential bonding conductor with a minimum cross-section 1 x 10 mm
(with, for example, an earth clamp (G 3/4) on the transducer housing).
3. Connect SAM 2 and the pressure transducer at the same equipotential bonding conductor. The
potential difference between both earthing points must be zero.
4. Connect the conductor screen at the pressure transducer to earth.

Rotary screw compressors always have an EMERGENCY mode. Piston compressors and
blowers may or may not have this facility.
6.12.3.1 Stations with EMERGENCY mode facility
■ In automatic mode, SAM 2 assumes the LOAD / IDLE regulation.
■ In manual mode, the machines run under the control of their own internal pressure regulation.
Machine with "External load control" input
When the machine is linked, the machine pressure regulation (mains pressure switch (-B1) or elec‐
tronic pressure control) remains in operation. The system automatically runs in emergency mode
via these pressure switches if power to the SAM 2 fails or the SAM 2 itself malfunctions, ensuring a
further supply of compressed air.

the SAM 2 load output" (-B1) is fitted in the machines to prevent one of the following:
■ The machine is overloaded
■ The pressure relief valve responds due to:
- switching points set too high
- defective master controller
- excessive pressure loss between the machine and the pressure transducer of SAM 2 .

7.12.1 Setting the Parameter
The fundamental pressure values of the station must be set in the Parameter menu.
7.12.1.1 Pressure range upper limit [pR]
You define the pressure margin by setting a pressure value above the required pressure.
For example, if you want a required pressure of 7.0 bar and a pressure margin of 0.5 bar,you must
specify 7.5 bar as value for the upper pressure margin.
7.12.1.2 Pressure range
The pressure margin is the difference resulting from the upper margin limit and the required pres‐
sure.
For energetic reasons, select the largest possible pressure margin. Practical values are 0.8–1.2
bar, for example. Lower values for the pressure margin result in more frequent machine motor
starts.
7.12.1.3 Required pressure [pREQ]
The required pressure is the pressure required by the consumers in the compressed air network
(measured with the "pressure transducer").
SAM 2 usually maintains the required pressure with a maximum deviation of 0.1 bar. For energetic
reasons, the operating pressure is to be set as low as possible, i.e., not higher as required for the
consumers within the compressed air network. A pressure of 1 bar higher than required causes ap‐
proximately 6 % more energy consumption.
7.12.1.4 Maximum pressure
Pressure high [ph] is a monitoring function. If the monitoring function is activated, the system is‐
sues a warning message as soon as the mains pressure exceeds the set threshold value for the
set time.
7.12.1.5 Minimum pressure
Pressure low [pt] is a monitoring function. If the monitoring function is activated, the system issues
a warning message as soon as the mains pressure falls below the set threshold value for the set
time.
No.: 901735 00 E
The monitoring function is provided in two variants:
■ Δpt: This monitoring function uses a pressure limit relative to the set required pressure.
■ pt: This monitoring function uses a pressure limit which is independent of the required pres‐
sure.
You cannot use both variants at the same time.

7.12.2.2 Required pressure minimum
The minimum working pressure represents the lower pressure limit which still ensures safe opera‐
tion for the consumers within the air network.
