Terminal strip
The power-on command is initiated by connecting a positive voltage at
input X11.2.
Static operation:
+24 V
= power-on
0 V = power-off
Edge-controlled operation:
Edge 0 to +24V = power-on
0 V = power-off
Serial interface
The power-on command is initiated by setting the ON bit in the interface
control word (refer to the USS protocol instructions).
Edge-controlled operation:
Edge 0 to 1
= power-on
0 = power-off
The interface is only activated for an edge control. The terminal strip
signals still keep their function. The command source is not changed-over
If the system is only to be powered-up and powered-down via the
interface, then input X11.2 “On” must be connected to terminal X11.1
“P24V” before the line supply voltage is connected, and the “Edge-
controlled operation” function must be selected. After the line supply
voltage is connected, an edge is not recognized at the terminal strip, and
the system can be powered-up via the interface.
The system can always be powered-down via the terminal strip.
The “ON” control bit is not taken into account if the interface is not
activated.
