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).
Language Active line Submenu Submenu Submenu Submenu
Numbering
Each menu is numbered. Not all menus may be displayed because the access to certain menus is restricted by the access
level, and some menus are displayed or hidden due to specific settings or options. 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 5.6.2.
Active line
The active line is always shown as white text on a dark background. Do not confuse this with the header which is also shown with white lettering on a black background.
Press «Enter» to open a menu in the active line. This opens the selected menu. Here, you can change parameters.

5.3.3 Setting parameters

In order to set a parameter in the active line of the selected menu, you must always switch to setting mode.
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.

5.4 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. When the controller is switched on, the lowest level of access (level 0) is activated. You have access to a further level: Access level 2
Access level 2 allows you to display and adjust further parameters. The access level will automatically return to level 0 after 10 minutes without any key being pressed.
Secure storage of the RFID Equipment Cards
You will receive 2 RFID Equipment Cards with each machine. They are stored in a plastic sleeve. This plastic sleeve is attached at the rear of the controller in the control cabinet. If you lose both RFID Equipment Cards, you can register a new RFID Equipment Card only after having entered the user name and the password. A new RFID Equipment Card may be registered by KAESER service subject to a fee, if the user name and the password are lost.

5.7 Operating modes and control modes

5.7.2 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 off by consumers, and to maintain the sys‐ tem pressure between the set minimum and maximum values. The control mode also rules the de‐ gree of energy efficiency of the machine.
The machine-dependant venting phase between the LOAD and READY operating modes ensures load changes at minimum material stresses.
The controller SIGMA CONTROL 2 can operate in the following modes:
■ DUAL
■ QUADRO
■ VARIO
■ CONTINUOUS
■ DYNAMIC
Option C1
■ MODULATING control
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 elapsed, the machine switches to READY.

QUADRO
Unlike the DUAL regulating mode, the machine will switch from LOAD to READY 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 READY after passing through IDLE.
In this control mode, the controller requires two specified times: The

5.7 Operating modes and control modes
DYNAMIC
Unlike the DUAL regulating mode, the machine will switch from LOAD to READY in DYNAMIC mode at low drive motor temperature.
And from LOAD via IDLE to READY at a high drive motor temperature. The lower the drive motor temperature, the sooner (and, therefore, more often and longer) it is
stopped.
Option C1
MODULATING control
The MODULATING control is an additional mechanical regulation. It continuously changes the de‐ livery volume within the machine's control range.
A control valve, the proportional controller, changes the degree of opening of the inlet valve when the machine transports compressed air into the air network (LOAD).
The load and power consumption of the drive motor rises and falls with the air demand.

5.7.3 Frequency-controlled drive (SFC)

If the machine runs in LOAD , the frequency converter compares the ACTUAL value with the TAR‐ GET value of the system pressure and regulates, depending on the difference, the speed of the compressor motor and the airend. 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 the 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 preset idling time has elapsed, the machine switches to READY.
VARIO/QUADRO/CONTINUOUS: The minimum controllable speed is reached and, depending on the air demand at the time, the ma‐
chine switches either to READY or to IDLE. The machine remains in IDLE at least for the duration of the
venting time
DYNAMIC: The minimum controllable speed is reached and, depending on the air temperature of the drive mo‐
tor the machine switches either to READY or to IDLE. The machine remains in IDLE at least for the duration of the

5.7 Operating modes and control modes
The inlet valve opens and the machine delivers compressed air. The frequency converter varies the speed of the drive motor according to the air demand. The
power consumption of the drive motor rises and falls according to air demand.

5.7.4 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.

8.4 Adjusting the pressure parameters of the machine
This section contains instructions for how to display and adjust the pressure parameters of the ma‐ chine.
The section is divided into the following sections:
■ 8.4.1: Displaying pressure parameters
■ 8.4.2: Configuring the pressure parameters
"Display" means that the parameter will only be shown. "Setting" means that the parameter can also be changed.
Parameters Explanation pRV Display:
Activating pressure of the safety relief valve on the oil separator tank.
pE Pressure increase.
Setting:
■ pE SP: Switching point for pressure increase; upper safety limit for machine maximum pressure; in an external LOAD control, this value is used to switch the machine from LOAD to IDLE in the event of a fault.
■ pE SD: Switching differential of pressure increase.
ΔpFC Limiting value for machines with frequency-controlled drive (SFC).
Setting:
■ dp FC: Limit of the lowest delivery quantity. When the value [switching point system setpoint pressure +dp FC] is exceeded, the compressor switches from LOAD to IDLE.
Nominal pressure
Setpoint pressure
System pressure low
Display: The compressor is designed for this pressure (maximum system pressure set‐
point). Setpoint pressure can be regulated to two values: pA and pB.
Setting:
■ Switching point pA or control pressure pA in machines with frequency convert‐ er (SFC).
■ Switching point pB or control pressure pB in machines with frequency convert‐ er (SFC).
A warning message is displayed when the limit value for the system pressure is reached.
78
Setting:
■ SD: Switching differential for system pressure low. ↓: Switching point for system pressure low.
■ Option: Configure the output signal. Warning message displayed or an additional output signal is sent, e.g., to a control center.
