                OPERATING MODE

                (*) We offer all devices who have a CONTACT

                 CAPACITY of min. 100 mA at 24 V DC with

                 hard gold-plated contacts. In this way the

                 CONTACT CAPACITY of min. 100 mA is only 4 mA.

                CONNECTION DIAGRAM

A supply voltage must be applied to terminals A1 and A2. Power LED illuminates and 24V DC is available at terminal S11. Terminals S12 and S22 must be connected according to the application example selected to meet the application requirements. To start the unit terminals S33 and S34 must be bridged with a normally open contact. The unit works if you close this contact. At this time the contacts 13-14 and 23-24 are closed. The LEDs channel 1 and channel 2 illuminate. In series to this start button an external contactor can be controlled. SAFE 2.2 can be used as control relay for safety mats and safety contact edges. These mats and edges must work like a normally opened contact. If someone steps on the mats or presses the contact edges the normally opened contact closes and SAFE 2.2 detects this.
