2-20 Installation and use
2.9 Switch the
AMS-8061 on
27) Switch the unit on using the level switch of the AMS-8061 Area Monitor
System.
2.10 Check the LEDs
status
28) Once switched the unit on, check the Led ON, Led ETHERNET, Led
MICRO SD Card and Led MODEM status as follows:
Led ON status
When the monitoring station is switched on, the Led ON is first lit with a
steady light for about 5 seconds, then starts to blink at the rate of one blink
per second, indicating that the monitoring station is active in normal Stand-
By conditions and
not in the low consumption mode.
The condition in which the LED blinks at a rate of one (brief) flash per
second indicating that the monitoring station is in Stand-By mode and not in
low consumption mode, are the following:
•
All the time the Modem is on Stand-By
Even if the user will disable most of the modem functions
through the software, the minimum periods at which the
internal modem would be ON (first hour after switch ON
without Low Battery alarm and from 11:00 to 11:45 when the
“Schedule for modem” and “Schedule for SMS” are set to
zero) the LED will be blinking every second
•
The time between acknowledgment of a command (via RS232,
USB, Ethernet) to about 60 seconds from the last command
received.
•
All the time between the attempts by the monitoring station to
establish a communication with the antenna to about 60 seconds
after correct acknowledgement of the connection.
After exiting this mode, the LED changes the manner of blinking to a (brief)
flash every three seconds, thus indicating the low consumption status. The
monitoring station remains in this status until an event rouses it and causes
the return to Stand-by status again.
Possible events are:
•
Modem switched on in Programmed or Spontaneous mode
•
Sending of a programmed or spontaneous SMS
•
Activity on the RS232, USB, Ethernet.
As indicated above, about 60 seconds after the termination of the event,
the LED resumes blinking at the frequency of 0,3 Hz.
The LED also has five additional statuses:
•
It blinks at a higher frequency than once per second during a
communication (from the beginning to the end) to indicate the
modem is in use.
•
It remains on with fixed light during data downloads.
•
It blinks red when the modem is on
•
It blinks green when the modem is off
•
It blinks orange when the Ethernet is connected
