TR-2100 User Manual
On Line
At turn on, this green LED will remain off until the TR-2100 has completed its internal self-
tests. If everything is satisfactory, the light will turn on and will stay on as long as the TR-
2100 is acquiring data. To put the system off line, see 'Disarm Triggering' below.
Data Available
This amber LED shows that the TR-2100 has triggered and that a data record is available for
downloading. After the directory with the new record is read by Display Station, the LED
will be switched off.
The TR-2100 is fitted with a hard drive and this LED will flicker as data is being written to
the drive.
Communications
During either local or remote communications, this amber LED is lit. This may be used by a
local operator to indicate that a remote connection is active. Only one communications
channel to Display Station can be active at any one time.
Attention
If the TR-2100 detects a problem during any of its regular internal self-tests, it will
illuminate this red LED. If this is seen, Display Station must be connected to read the TR-
2100's event log and find the source of the problem. There are four other LEDs that may be
illuminated for specific faults. These are described below.
GPS Fault
The TR-2100 uses a GPS receiver as an accurate source of timekeeping. If the system
detects a loss of satellites for more than 5 minutes, it will illuminate this LED. The TR-2100
will still operate normally on its internal oscillator, but the time reference may not be as
accurate.
Disk Fault
The TR-2100 uses a 3½" IDE disk drive to store all of its data. The system RAM is used as
a buffer area for fault data. When a record is complete, the data is transferred to the disk.
The disturbance logger and standard logger data are saved directly to the hard disk. If the
TR-2100 detects a problem with the hard disk, it will illuminate this LED.
Communications Fault
This LED is used to indicate that there is a problem with the remote communications
channel. This is either a dial-up modem or a network connection. If a modem is supplied, it
is checked regularly to ensure that it can communicate with the TR-2100.
Temperature Fault
The TR-2100 has a temperature sensor on each input board so that the system can
automatically correct offset and gain errors due to temperature variation. There are three
conditions where this LED is illuminated:
• The internal temperature has risen above 60°C
