Fault and Alarm Status
The ACS 160 provides fault and alarm status words for the external control
system. These data words are accessible only through the serial
communication link but not from the control panel.
Fault and alarm status words are located in parameter group 3. The group also
contains copies of the Control Word and Status Word. Group 3 parameters are
of read-only type; however, both alarm words can be reset by writing a zero to
them.
