y Ready for Use
The external Ready for use closes signal contact X99AB:1,2 when the power unit Ready for use is
pending and no monitoring has tripped. At the same time, the system generates internal Ready for
use. This signal is evaluated by the devices connected to X99A/X99B. Ready for use isindicated by
the green LED "BB int". The Feed/Feed-Back unit is ready for use if none of the before named mes
-
sages queues.
y Reset
Activating the reset input (apply +24 V to X99AB/5 and M24V to X99AB/6, optocoupler input) clears
the memory of the feed unit messages without the +24-V auxiliary voltage supply needing to be
switched off. For the duration of the reset, the system deactivates the internal and external Ready
for use. The reset signal must be pending for at least 50 ms.
y Feed Monitoring
Monitoring of the Feed Unit does not have direct influence on the power unit.
The Ready for use message to the feed unit, terminal strip X99A and X99B terminal 5 and the "Re-
served" terminal 6 are fed as an isolated signal to the controller and processed in the controller (see
manual of the controller).
NOTE
A missing Ready for use can result in a saved message with the connected devices. You must
clear the message by resetting at each of the devices individually.
