CONNECTION DIAGRAM
A supply voltage must be applied at terminals A1 and A2 in order to operate
the device. If this is done there is a voltage of 24V DC at terminals T11, T12
and T22 must be wired as shown in the application examples. To start the
unit terminal T11 must be bridged with terminal T34 by means of a closing
contact or terminal T34 must receive a 24V DC impulse (short time bridging
of the connection terminals T11-T34). If this is done contacts 13-14, 23-24,
33-34, 43-44, 53-54 and 63-64 close and 71-72, 81-82, 91-92 and 101-102
open. The LEDs channel 1 and channel 2 illuminate. Through terminal X1
and X2 the function of an external contactor can be monitored. Terminals
X1 and X2 must be bridged in order to operate the device.
