SIGMA CONTROL BASIC program module
KAESER KOMPRESSOREN GmbH 03.06.2003 www.kaeser.com
Make connections as follows
1.) Connections should only be made by a qualified electrician, following local
regulations. KAESER accepts no liability for damage caused by the retrofit.
2.) Holes must be drilled through the canopy near the power supply lines to provide entry
for the cables. The cable entry must be equipped with appropriate cable fittings or
grommets to exclude moisture and foreign bodies.
3.) The cable must be laid in such a way that no compressive or tensional stress is
imposed on it when the switch cabinet door is opened.
4.) A screwdriver DIN5264 A 0.4 x 2.5 should be used to open the spring-loaded
terminals. The screwdriver is inserted in the rectangular opening above the
corresponding terminal. Strip 8 mm of insulation from the end of the conductor for
insertion in the terminal.
5.) Make connection to pin 7 (input 14) and pin 9 (24V DC power supply) by means of X2
plug.
6.) Secure the cable so there is no tension on the X2 plug.
4. Removing the program module
1. The program module may not be removed from the controller.
2. Without the module there is no program in the controller.
The compressor will not run and the controller displays the error message "SYSTEM
ERROR, call service". When the module is inserted again the machine can operate.
