Statox 502 in Common Alarm Module Operation
The ex-works setting of the Statox 502 is Control Module mode. See chapter 8.3 for changing to Common
Alarm mode.
After being connected to power, the Statox 502 performs a self-test. Then the display shows the actual
firmware code. As far as there is no alarm signal on the bus, the display shows „COMMON OK“.
Figure 17: Start procedure in Common Alarm mode
When operating in common alarm mode, the module monitors the status of up to 25 control modules
connected to the bus. As soon as one control module generates an alarm, the common alarm modules LEDs,
relays, LCD and analog output go into the alarm status.
