Quick user guide Controller SIGMA CONTROL 2 SCREW FLUID 1.0.x.x 9_9450 00 USE 11 Checking the temperature sensor and overheating shutdown function 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.

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.

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. Service Manual Controller SIGMA CONTROL 2 SCREW FLUID 1.0.x.x No.: 9_9450 00 USE 4.6.2 Design and Function 4.6 Operating modes and control modes 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: Tab. 36 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 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. No.: 9_9450 00 USE Service Manual Controller SIGMA CONTROL 2 SCREW FLUID 1.0.x.x 25 4 Design and Function 4.6 Operating modes and control modes 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. 26 Service Manual Controller SIGMA CONTROL 2 SCREW FLUID 1.0.x.x No.: 9_9450 00 USE 4 Design and Function 4.7 MODULATING control 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.

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.
