                CONNECTION DIAGRAM

A supply voltage must be applied to terminals A1 and A2. The "Power" and "restart interlock" LEDīs illuminate. If this is done, a voltage of 24 V DC is be available on the terminal S11. Terminals S12 and S22 must be wired as shown in the application examples. To start the module, the terminals Y1 and Y2 must be bridged over normally open contact. In the following the contacts 13-14, 23-24 and 33-34  are closed.

The LEDīs of channel 1, channel 2 are illuminate and "restart interlock" must be switched off. In series to the start-button, wired on terminals Y1 and Y2, an external contactor can be controlled. Monitoring of the reset circuit can be configured by external bridge between terminals BR1 an BR2.
