11 Checking the temperature sensor and overheating
shutdown function
The machine should shut down if the airend discharge temperature (ADT) reaches a maximum of
230 °F.
SIGMA CONTROL 2 will simulate a higher temperature for checking this function.
For this purpose, SIGMA CONTROL 2 automatically determines an offset value to be displayed.
During the test mode, this Offset is added to the actual airend discharge temperature to cause the
machine to shut down prematurely.
In standard operation, SIGMA CONTROL 2 generates the "overtemperature" fault message when
the maximum airend discharge temperature is reached. Since the modified test temperature is 4 °F
below the fault message switching point for overtemperature, the system will not generate a fault
message in test mode.

Description
The main menu is the top menu level. You open the individual submenus in the main menu.
A scrollbar appears at the right side of the display if you open a menu with more than 6 lines. It
represents the currently visible portion of the menu. A short scrollbar thus indicates that the opened
menu is very long as only a small portion can be displayed.
The image above provides an example for the appearance of the main menu (without scrollbar).
Numbering
Each menu is numbered.
Because the access to certain menus is restricted to specific access rights, not all menus may be
shown.
For example, you can recognize subordinate menus in the menu structure by the number preced‐
ing their designation. The menu structure is explained in chapter 4.5.2.

setting mode.
You move to setting mode by:
pressing «Enter». The value of the parameter will flash indicating that it can be changed.
Changing parameters
Press «Enter». The value of the parameter will flash indicating that it can be changed.
The «Enter» key affects only the active line.
In some lines, you can change more than a single parameter.
In this case, you must first select the specific parameter with the «Left» or «Right» keys.
Resetting current parameters
In order to reset current parameters to Zero, activate the check box for Reset in the active line of
the display.
First, press «Enter» to switch into setting mode. The check box for Reset will flash.

4.4 Access rights
Access to the controller is governed by the user name combined with a password.
Users log on using an RFID Equipment Card by default. Alternatively, you can manually enter the
user name and the password.
Throughout this operating manual, the RFID Equipment Card will be simply called the "Equip‐
ment Card".
When the controller is switched on, the lowest level of access (level 0) is activated.
You have access to a further level: Level 2.
In level 2, you can display and specify further parameters and, for instance, reset the system pres‐
sure or the maintenance counters.
The access level will automatically return to level 0 after 10 minutes without any key being pressed.
4.4.1 Secure storage of the RFID Equipment Cards
You will receive 2 RFID Equipment Cards with each machine.
If both Equipment Cards are misplaced, you can register a new Equipment Card only after entering
the user name and the password. A new Equipment Card may registered by an authorized
KAESER service representative, subject to a fee, if the user name and the password are lost.

4.6 Operating modes and control modes
4.6.1 Operating modes
The machine operates in the following modes:
■ LOAD:
The inlet valve is open. The airend delivers compressed air to the distribution network.
The drive motor runs under full load.
■ IDLE:
The inlet valve is closed. The minimum pressure/check valve shuts off the oil separator from
the distribution network. The venting valve is open.
A small volume of air circulates through the bleed hole in the inlet valve, through the airend
and back to the inlet valve via the venting valve.
The drive motor runs without load and draws little current.
■ STANDSTILL:
The inlet valve is closed. The minimum pressure/check valve shuts off the oil separator from
the distribution network. The venting valve is open.
The drive motor is stopped.
■ MODULATING CONTROL:
With the help of a control valve (the proportional controller) the degree of opening of the inlet
valve is steplessly varied in response to the air demand. The airend delivers compressed air to
the distribution network.
The load and power consumption of the drive motor rises and falls with the air demand.
The regulating valve is factory set. The setting should not be changed without consultation with
an authorized KAESER service representative.

24 Service Manual Controller
SIGMA CONTROL 2 SCREW FLUID 1.0.x.x No.: 9_9450 00 USE
Option C1
4.6.2 Control modes
Using the selected control mode, the controller switches the machine between its various opera‐
tional states in order to compensate for air being drawn of by consumers and maintain system
pressure between the set minimum and maximum values. The control mode also rules the degree
of energy efficiency of the machine.
The machine-dependant venting phase between the LOAD and STANDSTILL operating modes en‐
sures load changes at minimum material stresses.
The controller SIGMA CONTROL 2 can operate in the following modes:
■ DUAL
■ QUADRO
■ VARIO
■ CONTINUOUS
■ DYNAMIC
Energy-efficient control modes for various applications:
Application Recommended
control mode
Compressed air station with one machine or several machines with com‐
parable delivery
VARIO
Machine for peak load in a compressed air station DUAL
Machine for intermediate load in a compressed air station VARIO
Machine for basic load in a compressed air station QUADRO
Tab. 36 Energy-efficient control modes
The SIGMA CONTROL 2 is factory set to DUAL control mode unless specifically ordered other‐
wise.
DUAL
In the DUAL control mode, the machine is switched back and forth between LOAD and IDLE to
maintain the machine working pressure between the preset minimum and maximum values. When
maximum pressure is reached, the machine switches to IDLE. When the preset
idling time
has
elapsed the machine switches to STANDSTILL.
The
idling time
is factory preset according to the maximum starting frequency of the drive motor.
The shorter the
idling time
setting, the sooner (and more frequently) the drive motor is stopped.
QUADRO
In contrast to the DUAL regulating mode, the machine will switch from LOAD to STANDSTILL in
QUADRO mode after periods with low compressed air consumption.
After periods with a high compressed air consumption, the machine will switch from LOAD to
STANDSTILL after passing through IDLE.
In this control mode, the controller requires two specified times: The
running time
and the
idle/
standstill time
.
The shorter these times are set, the sooner (and more frequently) the drive motor is stopped.

4.6 Operating modes and control modes
No.: 9_9450 00 USE
Service Manual Controller
SIGMA CONTROL 2 SCREW FLUID 1.0.x.x 25
VARIO
The VARIO mode is based on the DUAL control mode. The difference to DUAL is that the
idling
time
is automatically lengthened or shortened to compensate for higher or lower machine starting
frequencies.
CONTINUOUS
In the DUAL control mode, the machine is switched back and forth between LOAD and IDLE to
maintain the machine working pressure between the preset minimum and maximum values. When
maximum pressure is reached, the machine switches to IDLE. The motor is not stopped, i.e. the
machine does not switch to STANDSTILL.
DYNAMIC
In contrast to the DUAL regulating mode, the machine will switch from LOAD to STANDSTILL in
DYNAMIC mode at low drive motor temperature.
And from LOAD via IDLE to STANDSTILL at a high drive motor temperature.
The lower the drive motor temperature, the sooner (and, therefore, more often and longer) it is
stopped.
4.6.3 Frequency-controlled drive (SFC)
The frequency converter compares the actual network pressure with a target value and adjusts the
speed of the drive motor, and thereby the delivery of the compressor, accordingly.
The speed of the airend determines the rate of compressed air delivery and the working pressure.
If air consumption rises, the frequency converter increases motor speed and therefore increases
the volume of air delivered.
If air consumption drops, the converter reduces motor speed and therefore reduces the volume of
air delivered.
The network pressure remains constant – within the control range of the converter - regardless of
fluctuating air demand.
If network pressure exceeds the target value:
Outside the frequency converter's range of control the machine reverts to the selected control
mode.
DUAL:
The minimum controllable speed is reached and the machine switches to IDLE. The drive motor
runs unloaded with low power consumption.
When the idle period has elapsed, the machine switches to STANDSTILL.
VARIO/QUADRO/CONTINUOUS:
The minimum controllable speed is reached and, depending on the air demand at the time, the ma‐
chine switches either to IDLE or to STANDSTILL.
DYNAMIC:
The minimum controllable speed is reached and, depending on the air temperature of the drive mo‐
tor, the machine switches either to STANDSTILL or to IDLE.

4.6 Operating modes and control modes
26 Service Manual Controller
SIGMA CONTROL 2 SCREW FLUID 1.0.x.x No.: 9_9450 00 USE
If network pressure falls below the set-point:
The frequency converter runs the motor up to a speed at which air delivery matches the air de‐
mand.
The inlet valve opens and the machine delivers compressed air.
The converter varies the speed of the drive motor according to the air demand. The power con‐
sumption of the drive motor rises and falls according to air demand.
4.7 MODULATING control
With the help of a mechanical control valve (the proportional controller), the opening and closing of
the inlet valve is continuously varied in relation to the actual air demand. The airend delivers com‐
pressed air to the distribution network.
The load and power consumption of the drive motor rises and falls with the air demand.
To ensure optimal control on large compressors, the control air for the proportional controller is tak‐
en from an external air receiver.

8.6 Checking the temperature sensor and overheating shutdown func‐
tion
The machine should shut down if the airend discharge temperature (ADT) reaches a maximum of
230 °F.
SIGMA CONTROL 2 will simulate a higher temperature for checking this function.
For this purpose, SIGMA CONTROL 2 automatically determines an offset value to be displayed.
During the test mode, this Offset is added to the actual airend discharge temperature to cause the
machine to shut down prematurely.
In standard operation, SIGMA CONTROL 2 generates the "overtemperature" fault message when
the maximum airend discharge temperature is reached. Since the modified test temperature is 4 F
below the fault message switching point for overtemperature, the system will not generate a fault
message in test mode.
